BLAST CHILLER INTRODUCTION
THE BLAST CHILLER is the easiest and simplest way to chill foods safely without additional labor. All food
service operators prepare foods in advance or chill foods at the end of a workday. More often than not the foods
are chilled in standard refrigeration, often creating an unsafe time and temperature environment. In using a
BLAST CHILLER food products are produced in the same manner and with the same equipment which is
used for conventional food preparation and chilled in a BLAST CHILLER. The BLAST CHILLER
resembles a reach in refrigerator. The BLAST CHILLER is a unit that moves cool air at a high circulation
over the top and bottom of each pan thus ensuring a rapid even chilling time. Almost all foods are chilled
within 2 hours out of the danger zone 140°F to 41°F. The time necessary to bring the internal food temperature
to 41°F. (5°C) is affected by the food density, moisture content and the food’s ability to retain heat. Blast
chilled food has a shelf life of five days, including day of production and service. Blast chilling works well
with a wide range of menu items. Nearly any food product that can be portioned into a standard 2-1/2” hotel
pan can be successfully blast chilled. These systems are used for services from 50 to 10,000 meals per day.
STEPS IN THE BLAST CHILL PROCESS
1. Prepare all food products to the point of consumption. Within 30 minutes, portion into 2-1/2 inch deep
half-full pan or sheet pan at a depth of no more than 2 inches and weight of no more than 8 lbs.
2. Place pans of cooked product in the BLAST CHILLER and strategically place probe in the center of
the pan where the internal temperature is brought down to approximately 41°F (5°C) within 90 minutes.
3. At the completion of the “chill cycle” the pans of food product are removed and covered with either a
film wrap or stainless steel lid and labeled.
4. The product is stored in a refrigerator and maintained at a temperature between 33°F (1°C) and 38°F
(3°C).
5. The food product is rethermed just prior to the required meal service in bulk or individual portion.

UNPACKING INSTRUCTIONS
IMPORTANT:
It is highly recommended that your refrigerator or freezer be installed by an authorized
CresCor Service Agency (List enclosed)
A. Receiving Shipment
Upon arrival, examine the exterior of the shipment packaging for any signs of rough
handling.
If the cabinet is damaged, it should be noted on the delivery slip or bill of lading and signed
to that effect. A claim must be filed immediately against the carrier indicating the extent
and estimated cost of damage incurred.
All units are performance tested and thoroughly inspected prior to shipment. Upon leaving the
factory all units are in perfect condition and the carrier signs to this effect.
B. Uncrating Procedure
WARNING:
DO NOT, Under any Circumstances, Lay Your New Equipment Down on Either The Back,
Front, or Sides!!!
1. Check for any instructions printed on shipping carton.
2. Remove protective cardboard corners, sides and top.
3. Next remove the shipping skid.
4. If any concealed damage is discovered at this time, notify the carrier
retain all carton and packing materials until an inspection has been made or waived
by the carrier. Taking a photo of the damage is recommended.
CAUTION:
Exercise extreme caution when removing the wooden skid.
5. Please Note the Model and Serial Number located on the inside right hand wall of the unit.
Please take the time to write these numbers down and keep in a safe place. A space has been
supplied for this purpose on the last page of this manual. This will assure you quality service

in writing, and
[ Section 2-Installation ] [ Page 11 ]
C. Removing Plastic Film
Stainless steel surfaces are protected with plastic film when shipped. The film is easily removed
by grasping an edge corner of the film and pulling it off.
D. Locating Your new Blast Chill Unit
The cabinet should not be placed in the immediate vicinity of ranges, ovens and other heat
radiating equipment. This will help to increase efficiency as well as lower operating costs. Selfcontained refrigeration is standard on reach-in chillers. Adequate air ventilation is mandatory
for the condensing unit in order to operate efficiently and to prevent excessive and damaging
operating temperatures. The Blast Chiller should be in an ambient room temperature of 85° or
less.
E. Leveling
The cabinet must be standing level on all four casters for the self-closing doors to operate
properly and for proper drainage of condensation from the evaporator. Casters are nonadjustable, therefore the floor must be level.
F. Cleaning (refer to section 4)
G. Electrical Supply
All models (except the CCBC12-UA-100) are furnished with an electrical power cord & NEMA
plug, merely requiring that the appropriate NEMA receptacle is available at the installation
location. Model CCBC12-UA-100 requires a qualified electrician to furnish and install wiring
for the power supply. This must be connected to the identified terminals provided inside the
control panel. Refer to the appropriate wiring diagram furnished with the cabinet for guidance.
Electrical power of the current voltage, phase and ampacity must be supplied to the Blast Chiller.
The Chiller must have its own separate electrical circuit breaker with no other equipment or
appliance connected to that breaker. (Dedicated Circuit) See the cabinet data plate located on the
interior wall for the electrical requirements.
CHECK LIST (WITH POWER TURNED OFF)
***** EXAMINE THE FOLLOWING BEFORE START-UP! *****
CAUTION:
these checks to avoid the possibility of unexpected injury !!!
1. Check that above installation recommendations have been adhered to. Pay particular
attention to installation location for any potential excessive heat sources (oven, range,
etc.) or inadequate air ventilation conditions which can cause compressor overheating
problems and/or failure. If any such condition exists notify the owner to have the installer
correct before continuing.
2. Check refrigeration tubing for damage and that they are not touching or rubbing against
anything.
(continued)
Make sure the power to chiller is turned off prior to making
[ Section 2-Installation ] [ Page 12 ]
3. Make sure cabinet is sitting level with all four (4) casters (or legs) in contact with the
floor.
4. Also make sure the door stays open when opened past 90 degrees.
5. Inspect magnetic door gasket to be sure it is making contact on all four (4) sides. Also
make sure it is not cut, torn, twisted or otherwise deformed.
6. Check installation of shelves or pan slides .
7. Check electrical power source for correct voltage, phase and ampacity. Refer to cabinet
data plate for requirements.
8. Remove electrical control box cover and check all wiring connections for a secure hold.
On rare occasions, rough shipping and handling conditions can result in loosening of
connections resulting in electrical problems.
9. Make sure all miniature circuit breakers are turned on.
10. Check all fan blades. They should turn freely without touching anything as they spin.
11. Check electrical power supply cord and plug for any damage and be sure it is not routed
in a way that would permit anyone to trip over it.
[ Section 3-Operation ] [ Page 13]
GENERAL OPERATION OF BLAST CHILLER
All CRESCOR BLAST CHILLERS have 3 basic modes:
1. Normal refrigeration storage 1°C/34°F to 3°C/38°F
2. Blast chill hard –10°C/14°F
3. Blast chill soft 1°C/34°
Normal Cycle 1°/34°F to 3°C/38°F
This is the storage temperature at which the food can be held.
Blast Chill Cycle (hard or soft)
During the blast chill hard cycle the air temperature inside the cabinet should go down to
approximately -10°C/14°F. This is for the timed or probe chilling cycle. Most applications will
use the hard cycle mode. During soft chill the air temperature stays above 0°C/32°F.
START UP INFORMATION
After you have completed all eleven (11) steps of the checklist, you are now ready to perform the
following steps:
1. Sanitize the inside of the cabinet and probes.
2. Turn on BLAST CHILLER left standby button-Display panel will indicate cabinet
temperature.
3. There may be an indicator “A7”. This indicates that there has been a power failure.
4. Press the red “x” cancel button to cancel alarm.
5. Allow the cabinet to chill in standard refrigerator mode for at least 30 minutes.
6. Run BLAST CHILLER (See HOW TO OPERATE below) without food product to
ensure all equipment is performing correctly. Use warm pans of water and place
probe tips in water to make sure the system is operating.
Do not submerge probes!
HOW TO OPERATE
The following instructions apply to all modes of CRESCOR BLAST CHILLERS
1. Turn on the chiller at least one half hour before use.
2. Check that the chiller is operating at storage temperature. Cabinet temp should be
40°F or lower.
3. Load the products to be chilled (see Loading Section page 4)
4. By pressing button ‘1’, select the ‘Chill’ mode
By pressing button ‘2’, select the desired blast function: "Hard Blast" or "Soft Blast".
5.
( Use Hard Blast unless otherwise advised.)
(continued)
[ Section 3-Operation ] [ Page 14 ]
6) By pressing button ‘3’, select the Timer for the desired duration or probed blast. Default to
probe blast unless it is known how long a product will chill.
7) If a variety of products are used make sure one probe is strategically placed near the top
shelf, 1 in the center and 1 at a lower shelf. If a variety of products are used make sure one
probe is in the largest item to be chilled. Place the CCBC-4-35 probe in the most difficult
to chill item located on shelf 2 or 3.
8) When you are happy with your selected program press the "D" to start the blast cycle.
9) If you are not happy with your selection press the "x" button to cancel your 1/2/3. If
cancelled repeat the above steps.
10) The blast chilling will begin.
TIP: You may open the door during blast chilling. This will not interrupt the cycle. If you add
additional food product make sure to use an Unused Clean probe in the product.
On completion of the blast chill cycle, when the product has reached 37°F, a buzzer will sound,
and “DEF” will be displayed in the “CABINET TEMP” window of the control panel. “DEF”
indicates the unit is defrosting. The blast chiller converts to a standard refrigerator.
During the defrost operation the temperature in the chiller will not exceed +3°C/38°F and it is
therefore safe to leave products in the chiller during the defrost cycle.
NOTE: Product can be set for blast chilling at the end of the labor shift. The products will store
safely in refrigeration hold mode until the next shift up to 24 hours.
BLAST CHILL CYCLE/MODES
All BLAST CHILLERS allow the operator to use any of the 4 pre-programmed timed cycle and
a probe control blast chilling cycle with the option of soft or hard blast.
PROBE CONTROLLED
The probe blast chill cycle functions with the internal probe(s) supplied. The probe monitors the
core temperature of the food and will not permit the blast cycle to stop until the default
temperature of 3°C/38°F is reached. The last product to reach 3°C 38°F will discontinue the
blast chill cycle.
When controlling the cycle with the food probe, make certain that the probe or probes are located
in the center of the product before the blast cycle is started. On BLAST CHILLERS equipped
with three food probes the cycle will not finish until all three probes have reached the correct
temperature.
CAUTION:
Easier to chill items may actually freeze prior to the end of the blast chill cycle of the harder to
chill item.
[ Section 3-Operation ] [ Page 15]
To activate a blast chill cycle you must:
1. Choose the required store mode with button 1
2. Choose the require blast type with button 2
(select hard blast unless all items chilling are delicate)
3. Choose the blast duration or probe with button 3
(select probe unless you know how long it takes the product to chill)
As each selection is made the indicator LED will illuminate to show what is chosen.
Press the “D”to accept, or “x” to cancel.
At the end of the blast chill cycle there will be an audible alarm, which will cancel automatically
after 15 minutes. (It may also be cancelled with the “x” button.)
After the blast chill cycle the cabinet will revert to a standard refrigeration mode appropriate to
store the foods until ready to use or transfer.
LOADING OF PRODUCT
1. All food products should be placed in either a 2-1/2” hotel pan or a sheet pan.
2. With the exception of roasted meats, all products should not be more than 2” in depth.
1-1/2” is recommended for very dense items such a lasagna and beef stew.
3. There should not be more than 7 lbs. of product per shelf.
4. Roast meats should be cut in ½ or 1/3 to allow for more effective chilling.
5. All Products should be blast chilled uncovered unless a “skin” may be formed (in
cream soups and sauces).*
6. Creamed soups and sauces should be covered with plastic wrap. The plastic wrap
should be touching the product to allow quick chilling. *
7. Probe(s) should be placed in the center of the pan or roast meat.
DEFAULT MODE
To save time for repeated identical blast operations, the blast selections are remembered, so
when 1-2-3 are pressed again, the selections automatically adopt the previous settings on the first
push. So to repeat a blast chill mode, just push 1 2 3 “D”.
DEFROST
At the end of each cycle, the defrost cycle will automatically clear any ice from the evaporator.
During operation in storage mode a defrost will be performed automatically at the factory pre-set
interval of 6 hours.
*see general rules of thumb pg. 30 for more information.
[ Section 3-Operation ] [ Page 16]
If a blast cycle is cancelled and the defrost thermostat is measuring 1°C/32°F or less, the BLAST
CHILLER automatically goes into a defrost cycle.
When the BLAST CHILLER is in the defrost mode the “Cabinet Temp” window of the control
panel will display “DEF” During the defrost cycle some fans will stop running. This is normal.
When the defrost cycle is finished the compressor will run for approximately 90 seconds before
the fans operate.
Following every defrost period there is a 3 minute period during which a blast cycle cannot be
selected. This short interval is to allow for the water created by the defrost mode to dissipate.
The cabinet is now ready to start another blast cycle if desired.
During the defrost operation it is safe to leave products inside the blast chiller.
[ Section 3-Operation ] [ Page 17]
PRINTER
If equipped, the printer is activated after each blast cycle. The printer provides hard copy
historical data of cabinet performance or warning tickets to archive or act upon.
The following formats are available:
Midnight Ticket
At midnight, a ticket is automatically printed for archiving in the morning. The midnight ticket
provides the following information:
- Time and date of printout and cabinet number
- Cabinet temperature at time of printout
- A graph of cabinet temperature over the preceding 24 hours
Demand Ticket
A ticket may be requested from the control panel by holding the printer 'On/Off' button for five
(5) seconds. This ticket provides the same information as the midnight ticket except that up to
seven (7) days of historical data are printed.
Alarm or Warning Ticket
A ticket is automatically printed if any condition is detected by the microcontroller, which may
need attention. The print function may be terminated by pressing the printer 'On/Off' button.
Main Power Failure Ticket
If the main power fails for more than five (5) seconds a ticket is automatically printed which
gives the time of power failure and the time at which power is stored.
Sensor Failure Ticket
If the controller detects that one of its sensors has failed, then a warning ticket will be printed.
Power Failure
A power cut does not cause the loss of any accumulated historical data and no re-programming is
necessary. The controller's battery is continually charged and provides emergency back up under
normal power failure conditions.

1. Compressor not running:
(a) Manually close compressor contactor (if utilized) temporarily to see if
compressor runs.
(b) If compressor runs, check compressor control circuit for problem.
(1) Is the Dual Pressure Control open?
- Check for correct settings
- Low or no refrigerant charge
- Liquid Line Solenoid Valve (if used) not opening?
(c) If the compressor doesn't run, check if you have power to compressor
terminals.
(1) If no power to terminals, trace back until power is found. Correct
problem.
- If single phase, check start relay and capacitor(s).
(2) If power is present at compressor terminals, check for stripped
compressor overload and/or "open" or grounded compressor-motor
windings.
2. Compressor does run:
(a) Compressor short cycles.
(1) Check DPC settings. Cut-in and/or differential may need to be
adjusted.
(2) Check refrigerant charge may be low.
- If low, or no charge, check for leaks, repair and recharge as
necessary.
(3) Check if thermostatic expansion valve is feeding properly.
(4) Check Chiller Store Thermostat ("St 1") and Differential ("Dt 1")
settings.
(5) Check the "fin" and "air on" thermocouples at main PCB to make sure
they are not interchanged.
(continued)
[ Section 5- Troubleshooting ] [ Page 21 ]
3. Compressor runs continuously.
(1) Check compressor for "pumping" efficiency.
(2) Door not closed tight or gasket leaking.
(3) If no DPC, or if DPC set too low to open, check refrigerant charge
and/or thermostatic expansion valve for adequate feeding.
Cabinet has power, display shows "Sto", but load of hot food takes extremely long to chill:
1. "Sto" is the storage mode and cannot chill food properly. You must first choose a
"PROGRAM" and then press "BLAST" in order to make the machine do a blast chill
cycle to quickly chill hot food.
In "BLAST" mode, unit runs, but doesn't chill the food fast enough.
1. Food too "thick" - limit 2 inches maximum for optimum performance.
2. Food too hot when placed inside - temperatures above 160°F increase pull-down time
proportionally.
3. Too much food - exceeding rated pounds of capacity increases pull-down time
proportionally.
4. Food covered (air trapped between food and cover is and insulator).
5. Container too large (distance from outside of container to center of food within is too
great, shouldn’t exceed 2 inches for optimum performance).
6. Container material is plastic (an insulator) instead of metal (a conductor).
7. If cabinet was off did not pre-chill before loading with hot food.
8. If using timed program, incorrect amount of time being selected.
9. Mechanical problem:
(a) Inadequate refrigerant charge.
(b) Thermostatic Expansion Valve defective.
(c) Evaporator fan(s) not working.
(d) Evaporator coil iced (see below for possible causes).
(e) Inadequate refrigeration (BTUH) capacity:
- Condensing unit ambient, or too high
- Condenser fan not working (if air cooled)
- Condenser dirty
- Compressor inefficient (or defective)
- Refrigerant line restriction
Evaporator coil iced:
1. Check how cabinet is being operated:
(a) Placing load of hot food inside and merely closing door is improper use.
Doing this keeps unit in the storage ("Sto") mode resulting in extremely long
pull-down times and does not initiate an automatic defrost. As a result the
evaporator coil becomes heavily iced.
(b) Must run a "BLAST" cycle for automatic defrosting to occur.
(continued)
[Section 5-Troubleshooting ] [ Page 22 ]
2. Door not shut tight
3. Gaskets leaking
4. Check defrost heater operator (if used):
(a) Defective heater
(b) Blown fuse (if used)
(c) Defective "klixon" if used
5. Check defrost settings:
(a) Check defrost thermostat ("St 5") setting
(b) Check defrost differential ("dt 5") setting
(c) Check Defrost Period Switch on main PCB inside control box
(d) Check Defrost Length Switch on main PCB control box.
6. Check that ambient temperature has not exceeded 100°F or 100% humidity.
Display reads - 58° F
1. Thermocouple is "open" :
(a) If food probe, check the make sure it's plugged into probe receptacle properly
(b) Check for loosened thermocouple wire connection at all connections
(c) Check for broken or cut thermocouple wire
(d) Temperature display not believable - responds in reverse:
- Polarity of thermocouple wire is reversed
Evaporator won't run:
1. Breaker not on (if equipped)
2. Motor overload tripped (if equipped)
3. In post-defrost "Drip" period
4. "Fan door" switch is open (if equipped)
5. Blown fuse (if used)
6. Defective contactor (if equipped)
7. Motor defective
Printer problems (if equipped) :
1. Printer doesn't run:
(a) "Link" (jumper) on main PCB not installed
(b) Damaged communications "ribbon" cable
(c) Defective printer
(d) Defective PCB
2. Printer "runs", but no paper comes out:
(a) Check if paper roll is loaded
(b) Check for jammed paper tape -
- Before loading a new roll, make sure free end of tape is pulled
completely away from the roll. Remove any paper residue. (The
residue will undoubtedly result in a paper jam).
- Carefully remove any paper residue from printer platen, otherwise
another jam could occur.
(c) Check for proper tape feed
3. Printer runs, but paper comes out with no printing:
(a) Check if printer has ribbon cartridge installed
(b) Check ribbon - condition may be out of ink, dried out, or torn
[ Section 5-Troubleshooting ] [ Page 23 ]
(c) Check make sure ribbon cartridge is properly installed - both sides snapped in
place
4. Printer is printing backwards and all characters reversed
(a) Paper tape is feeding incorrectly over top of printer ribbon. This can readily
occur when inserting a ribbon cartridge with paper tape still protruding from
the printer. The ribbon must be on top of the paper in order to print
correctly.
5. Paper rolls and ribbon cartridges are available from CresCor Authorized Parts
Distributors.
Odors inside cabinet:
1. Spilled food inside - clean as required
2. If not being used for a long period of time, turn off, clean interior and keep door open
to ventilate. Alternatively after cleaning, place and odor absorbent such as baking
soda inside with the door kept closed. Remove before restarting.
Alarm conditions:
1. Cabinet wall temperature above 38°F more than 60 minutes
2. Defrost termination on time instead of temperature
3. Compressor overheating (if temperature is greater than 217°F for 1 minute)
4. Compressor run (if the compressor runs continuously for more than 6 hours in either
blast mode or storage mode)
5. Faulty sensor (including food probe)
6. Loss of power for 5 seconds or more
7. Dead battery
Food dried out
1. Uncovered containers
2. Left in storage too long
Food frozen
1. Too long blast cycle
(a) Choose a shorter timed program
(b) Use the probe program
2. Uneven food portions-thinner foods can freeze by the time thicker portions reach
temperature
3. Monitor temperatures more frequently if uneven food loads and remove those when
reaching end temperature
4. Food probe defective
5. Stat 1 set too warm
Food not cold enough
1. Timed cycle too short
2. Stat 1 set too warm
3. Food probe tip not in center of food
4. Defective probe

General Rules of Thumb [ Page 31 ]
Pre-Chill the cabinet for thirty (30) minutes before you do first load.
(to remove interior residual heat)
Doubling the food thickness triples the pull-down time.
Don't stack food or containers on top of or alongside of each other.
(this increases the "thickness)
Covering the food increases pull-down time by 10%-30%.
Pull-down rate initially is about 2°F per minute and approaching final temperature is about 2
minutes per degree F.
"A watched pot never boils"
Factors affecting blast chill pull-down times:
(A) Initial food temperatures
(The hotter the initial food temp., the longer the pull-down time)
(B) Final food temp. (the colder the final temp., the longer the pull-down time)
(C) Food "thickness"(the greater the distance from geometric "core" center of food to its
surface, the longer the pull-down time)
(D) Food density (the greater the density, the longer the pull-down time)
(E) Container surface area(the smaller the surface area, the longer the pull-down time)
(F) Container material (metals are conductors which will shorten the length of pull-down
time, while plastics are insulators which will increase pull-down time)
(G) Covering material (metal preferred, same reasons as above)
(H) Covering method (Covering which is in direct contact with the food will pull-down
quicker than covering that is stretched tight leaving a "dead air" space between cover
and food. Air acts as an insulator and will increase the pull-down time)
(I) Amount (weight) of food put in as compared to rated capacity (exceeding rated
capacity will lengthen the time of pull-down)

MEATS
Roasted Meats
Roasted meats should be prepared according to the recipe using roast guidelines for each
product.
Cook according to recipe. If sauce or gravy is required, it should be prepared and chilled
separately from the portioned meat.
Turkey/Chicken
Cook turkey or chicken whole or breasts according to directions to 170° F. (76° C.).
Blast chill immediately. Slice product to a 1/4" thickness, single layered. Pre-cooked
turkey products do not require roasting.
*
Roast Beef (top round)
- Follow recipe and roast guidelines. Recommended
doneness for rethermalization is about 140° F. (60° C.). Top round should be
quartered and placed in the blast chiller. If roast beef is used for cold sandwiches,
the end cooking temperature may be higher. If medium doneness is desired, roast
to 150° F. (65° C.). Do not overcook.
Pork Roast
- Follow recipe and roast guidelines. Recommended doneness for
rethermalization is 165° to 170° F. (74° to 76° C.). Do not overcook or product
will be dry.
Lamb Roast
- Follow recipe and roast guidelines. Recommended doneness for
rethermalization is 155° F. (68° C.). Do not overcook.
Proportioned Meats (hamburger patty, pork chop, Salisbury steak, etc.)
Steak (filet, strip, ribeye)
- Broil steak to medium rare or preferred stage of
doneness. Blast chill immediately.
Salisbury Steak
- Bake to 165° F. (74° C.) Drain well, remove all grease. Blast
chill. Add gravy after steak is chilled.
Pork Chops/Cutlets
- Breaded, baked, or broiled chop is heated only to 165° F.
(74° C.) and blast chilled immediately. Add sauce or gravy after chilling.
[Page 35]
Seafood
- Prepare all fish fillets according to recipe for breaded, baked, broiled,
Fish
steamed, etc. Be careful not to overcook. Blast chill immediately.
Shrimp/Scallops/Shellfish
immediately. Be careful not to overcook. If prepared with a sauce (creole, etc.),
cook the sauce separate and mix together prior to retherm.
Casseroles and Stews
Stew and casseroles are very successful in cook/chill and rethermalization. Most recipes
should require little change for cook/chill. Products should be moist but hold form when
plated. Prepare and blast chill in 2-1/2" full pans.
Lasagna
Prepared from scratch, follow the recipe; do not overcook. Blast chill.
Beef Stew/Stroganoff, etc.
recipe. Blast chill.
Chicken/Turkey/Beef Pot Pie
sauce separately from the crust, pastry, or biscuit. Top product after chilling or at
point of rethermalization.
Stir Frys
Pasta Casserole (Mac & Cheese, Turkey Tetrazzini)
from pasta. Blast chill. Mix product together chilled and rethermed.
Sauces and Gravies
For conventionally prepared gravies and sauces, substitute a portion of the flour or
cornstarch with a modified starch. A substitute of 30 to 50% by weight is recommended.
In preparing these sauces and gravies with the modified starch, the product must reach
170° F. (76° C.) and be held at the temperature for a minimum of 5 minutes. If this is not
done, the gravy or sauce will thicken during the chilled storage. To reduce the risk of
rancidity during refrigerated storage, use broth bases rather than meat or poultry
drippings. Commercial gravy or sauce bases contain modified starches and can be
substituted for conventionally prepared products.
Sandwiches/Specialty Items
See CresCor Retherm Oven Time and Temperature chart on Page 60 in CresCor
cookbook.
- Brown off convenience lasagna to remove extra moisture and blast chill.
– Sauté / steam until meat is done and vegetables are crisp.
- Prepare according to recipe and blast chill
- Cook/steam meat until tender. Prepare as stated in
- Prepare the chicken/turkey/beef and vegetable
- Prepare sauce separately
[Page 36]
SOUPS
Conventional Soup
Prepare conventionally. For creamed soups, substitute a modified starch for a portion of
the thickening agent by 30 to 50%.
Canned Soup
No cooking is necessary for broth based soups. Cream soups should be diluted with milk
or water, mixed completely, and blast chilled.
Frozen Soup
Follow instructions on the soup container for preparing soup, blend thoroughly, and blast
chill.
VEGETABLES
Add seasonings to vegetables prior to panning. If margarine is added, a more even
distribution will occur with liquid margarine.
Frozen Vegetables
Frozen vegetables do not require cooking before rethermalization.
For bulk rethermalization, vegetables do not need to be cooked or blast chilled before
service and should be prepared as in conventional production.
Canned Vegetables
Canned vegetables do not require any cooking. All canned vegetables can easily be bulk
rethermed with little liquid remaining.
Fresh Vegetables
Many fresh vegetables can be used in cook/chill. The desired texture of the product will
determine the preparation procedure.
Zucchini/Yellow Squash
Steam or stir fry to desired consistency then blast chill.
Broiled Tomato
and blast chill immediately. Tomato will continue baking during rethermalization.
Slice in half and sprinkle on topping. Broil to brown topping
[Page 37]
Broccoli/Cauliflower/Green Beans/Carrots
bite size and broccoli and cauliflower in flowerets. Steam to desired doneness,
then blast chill.
Stuffed Vegetables (eggplant, zucchini)
shell and blast chill or place in ice bath. Stuff vegetable shell and blast chill to
bring temperature down from time of assembly.
Grilled Vegetables
Grill according to recipe. Place in 2-1/2" pan and blast chill.
POTATOES
Occasionally, "graying" or slight darkening of the cut surfaces of some cooked potatoes
will occur during chilling. This is an oxidation reaction and varies with the variety of
potato, soil, and weather conditions. Varieties that most often exhibit darkening are:
Irish, Ontario, Norland, and Red Pontiac.
Potatoes are fully cooked before blast chilling. Canned potatoes, well drained, can be
used without further cooking.
Mashed Potato (flakes or powder)
Follow recipe according to the package. Product should be smooth, easy to scoop, and
hold its form loosely at the point of blast chilling. Product should stay at that consistency
after blast chilling. If the product becomes stiff or dry, add water and stir into product.
Mashed Potato (fresh)
Follow recipe. Potatoes should be very soft before mashing and adding liquid. Follow
same consistency rule as for flake or powder potatoes. Cover with plastic and blast chill.
Fresh mashed potatoes should not be made more than 48 hours in advance to prevent
discoloration.
Baked Potato
Depending on the size of the potato, cut in half or fourths. Boil, steam, or bake potato to
complete doneness, then chill.
French Fried Potato
For best results, oven bake vs. deep fat frying is recommended. Steak fries are preferred
over a crinkle cut or shoe string potato. Tator tots and potato wedges also rethermalize
well. Bake according to recipe or package and blast chill.

RICE
Prepare according to standardized recipe, then blast chill. If rethermalized product is dry,
liquid may be added.
PASTA AND NOODLES
Cook to al dente, rinse well with cold water, then chill. Chill in 2-1/2" pans with water
with ice added. Drain partially before retherming. The best way to heat pasta is to run it
under hot water or dunk it into boiling water for 30 seconds.
FRIED FOODS
It is difficult to achieve a crispy, chewy fried product with an advanced preparation food
process. For best results, oven frying is recommended. If deep fat frying is still your
choice, use crumb breading instead of batter. Fry in clean, hot oil, and drain well before
chilling. Do not attempt to prepare further than one day ahead to avoid excess moisture.
Use meat items with little or no bone to get a drier product. Fried foods should be
produced conventionally when possible.
CEREALS
Cooked cereals such as oatmeal and grits continue to thicken when chilled and held under
refrigerated storage. To obtain a desirable product, follow the following procedures.
Cream of Wheat / Grits
Prepare recipe according to the directions. At the end of cooking, add 50% more water
and use a wire whip to stir in the water. Blast chill. The product should be the
consistency of pudding. If it is not, add water. Use a wire whip and stir to a pudding
consistency.
Oatmeal
Add 30% more liquid and follow recipe.
EGGS
Poached Egg
If a poached egg must be served, cook to firm stage.
Procedure:
• Spray a 1/2 steam table pan (2" deep) with any type release agent (e.g. Pam™)
• Fill with cold water, add 1/4 cup vinegar.
[Page 39]
• Add a 2" perforated insert to pan.
• Break eggs (25-30) in separate bowl and slip onto the 1/2 pan insert.
• Steam a maximum of 3 minutes (time should be tested at each facility as
equipment performance will vary at each location).
• Lift perforated insert out of pan and plunge into ice water to retard cooking. The
whites will still have a wet, glossy look, but should hold shape.
• Lift eggs out with slotted spoon and drain well before plating on trayline. Chill
and store until trayline.
• Eggs could be left to chill on perforated insert, drain well.
Scrambled Egg
A pasteurized egg product is recommended. Prepare to a soft, loose consistency.
Remove from heat source, cover with plastic wrap, and immediately blast chill.
Omelets
Frozen convenience product must be fully tempered prior to assembly. For omelets
prepared conventionally, follow existing standardized recipe. Omelet should be slightly
undercooked, then blast chilled.
Hard Cooked Egg
Cook in usual manner and chill immediately. Store covered in walk-in cooler.
PANCAKES/FRENCH TOAST/WAFFLES
For pancakes/French toast prepared conventionally, shingle, stack, and blast chill for a
short period of time (approximately 15 minutes). French toast made with Texas toast
blast chills and retherms with the best quality.
BREAKFAST MEAT
Sausage
Sausage patties are preferred over links for best heating. Cook sausage to 165° F.
(74° C.), then drain well. Blast chill.
Bacon
Cook to point of service. Presentation is best if bacon is cooked to the crisp stage,
drained, and patted dry with paper towels to remove excess fat. Blast chill.

BREAKFAST BURRITOS/CREPES
Burrito and crepe filling is prepared conventionally and chilled. When filling is chilled,
then fill crepes and burritos. Blast chill filled products.
BREAKFAST SANDWICHES

for additional 15-20 minutes.
HASH BROWNS/OVEN FRIES
For both convenience and freshness, prepare to the point of complete doneness, then blast
chill. Product should not be too dry.
*Please note: The internal temperatures may continue to increase in the
beginning of the blast chill cycle.
