This mode will steam a full or partial load of a single product, or multiple products

without transfer of flavors. When steaming multiple products, however, individual

roduct cooking times must be taken into consideration. The non-pressurized

atmosphere of the Combitherm also provides the ability to open the door during the

steam mode in order to monitor products more closely throughout the steaming process.

STEAM

Per forated, 2-1/2" deep pans (65mm) are particularly suitable for use in this program mode. These pans will provide a shorter cooking time and will prevent product over-cooking at the bottom of the pan.

Separate ice-encased vegetables before steaming to assure more even cooking.

A variety of products can be steamed at the same time but attention must be paid to the different cooking times required for each food product.

Butter and season vegetables after steaming.

QUICK STEAMING

Quick steaming is suitable for hearty, root-type vegetables such as potatoes, legumes, and cabbage.

Quick steaming provides a cooking time which is approximately 10-percent shorter than the regular steam mode temperature of 212°F (100°C).

Set the steam cooking temperature between 221°F (105°C) and 230°F (110°C) for small loads and between 230°F (110°C) and 248°F (120°C) for full loads.

LOW TEMP STEAM

The low temperature steam mode will function whenever the oven compartment temperature is below 212°F (100°C).

Proof yeast dough at a temperature setting of 90°F to 110°F (32°C to 43°C).

It will take longer to steam products using the low temperature steam mode.

Steaming sausages in low temperature steam prevents cracked or peeling skins.

Use low temperature steam for delicate foods such as shrimp, fish, seafood, and crème caramel.

Steam long-grain rice using approximately 1-part rice to approximately 1-1/2-parts water or seasoned liquid.

Steam durum wheat noodles in unperforated pans using 1-part noodles to 5-parts cold water.

For best results, low temperature steam all delicate food items at a temperature of 210°F (99°C) or below.

The Combination mode will prove to be the most versatile and widely used mode the Combitherm oven has to offer. It will produce the best possible results on the widest variety of products — all within the shortest period of time. The unique control function of this mode enables the operator to roast or bake with a combination of

team and convection heat. In addition to shorter cooking times, this combination of

s steam and heat offers less product shrinkage and more moisture retention than obtained in a standard convection oven.

Due to the automatic steam adjustment, the door can be opened at any time during a cooking operation. Be certain to observe the safety war ning when opening the oven door.

The Combination mode is particularly efficient when used for baking, broiling, grilling, stewing, braising, and roasting.

When using the Combination mode, cooking temperatures can be reduced 10- to 20-percent below the temperatures used for conventional cooking methods.

Cooking time will be reduced approximately 40-percent when cooking at the same temperature used for convection oven cooking and up to 50- to 60-percent less time when cooking at the same temperature used for a conventional oven.

Food browning in the Combitherm begins at a cooking temperature of approximately 248°F (120°C).

A higher cooking temperature results in heavier browning but also results in greater product weight loss. To achieve additional browning use the Moisture Vent Key or set Gold-n-Brown into the product procedure. Gold-n-Brown is particularly useful for adding color to high moisture products such as chicken and other poultry items or for additional browning of full loads and other moist products.

The Combination mode provides even browning without the necessity to turn the pans.

For more even cooking, do not cook in pans deeper than 4-inches (100mm).

he Convection mode operates with hot circulated air within a temperature range

The Convection mode works best with foods containing little moisture or for very moist food which require a dryer finished product.

For baking, preheat the Combitherm at a temperature of 36°F to 54°F (20°C to 30°C) above the baking temperature required. Once preheated, reset the temperature as required.

A higher cooking temperature results in heavier browning but also results in greater product weight loss. To achieve additional browning use the Moisture Vent Key or set the Browning Feature into the product procedure.

To prevent the surface of food from excessive drying, the fan will not engage if the inter nal oven temperature is above 212°F (100°C) and the set oven temperature is below 212°F (100°C).

RETHERM MODE CHEF OPERATING TIPS

Since plated meals consist of dissimilar products, there are several important factors

to consider in order to produce the finest results. Product density (compactness),

hickness, quantity of product on each plate, and quantity of plates all relate to the

length of time necessary to reheat. Again, experience is the best method to

determine reheating time. Once the time has been deter mined and recorded for a

specific meal, the results will be consistent for future reheating times.

HEL P F U L HINTS FOR REHEATING ON TH E PLATE

•

ALL FOOD COMPONENTS ON THE PLATE SHOULD BE OF SIMILAR DENSITIES.

•

ALL FOOD COMPONENTS ON THE PLATE SHOULD BE SIMILAR IN THICKNESS.

•

ARRANGE ALL FOOD COMPONENTS EVENLY ON THE PLATE.

•

AVOID EXCESSIVE OVERLAPPING OF PRODUCT.

•

SAUCES MUST BE HEATED AND ADDED TO PRODUCT AFTER REHEATING.

•

A MIXED VARIETY OF MEALS CAN BE REHEATED AT THE SAME TIME.

• À LA CARTE R ETHERMALIZATION

À la carte rethermalization is designed to take a single plate from a refrigerated temperature to serving temperature for immediate service. Plates are prepared in advance, covered, and refrigerated. Preheat the Combither m oven. Remove plate from refrigeration and place in the oven at 275°F (135°C) for an uncovered plate or 300°F (150°C) for a covered plate. Plates with meat components will take more time than plates containing all vegetable components. Follow internal temperature requirements for reheating and allow for override time. After reheating, remove the plate from the oven, add any sauces, garnish, and serve. This process can be repeated as required.

For the most efficient continuous service, it is suggested that the Combitherm oven be dedicated to the rethermalization process during serving hours.

• B A N QUET RE THERMALIZATION

Banquet rethermalization is designed for high volume, full or partial load (multiple plate) reheating. For maximum efficiency, it is essential that volume rethermalization be used in conjunction with the utilization of holding cabinets to keep rether malized food at proper temperatures.

Plates are assembled in advance, covered, and refrigerated or loaded on the roll-in cart and refrigerated. Preheat the Combitherm oven at 275°F (135°C) for uncovered plates or 300°F (150°C) for covered plates. Remove plates or the roll-in cart from refrigeration, load in the oven and set timer as

required. Follow inter nal temperature requirements for reheating and allow for override time. Remove the plates or roll-in cart from the Combitherm and roll into the companion holding cabinet. Relocate the holding cabinet to the banquet service area.

• R E T HERMALIZING PREFABRICATED AND

VACUUM- PACKED FROZEN FOODS

For bulk product rethermalization, completely defrost product bags in walk-in cooler. DO NOT REMOVE PRODUCT FROM THE BAG. Load thawed bags in preheated oven and rethermalize in the Low Temperature Steam mode until the required internal temperature is reached. Place rethermalized bags in a preheated holding cabinet set at 140° to 165°F (60° to 74°C) until ready for service.

For large volume on-the-plate regeneration, defrost bags in walk-in cooler. Open bags and plate per menu requirements in a ( refrigerated room. Cover plates, place on Alto-Shaam roll-in cart (trolley), and roll into Combitherm oven preheated at 275°F (135°C).

Regenerate in the Convection mode for 3 to 5 minutes. Switch to the Retherm mode for an additional 3 minutes or more if required. Transfer full trolley to a preheated holding cabinet set at 160°F (71°C) until ready for service. In the case of meat cooked to rare, set the cabinet at 140°F (60°C).

MA X IMUM) 55°F (13°C)

PLATE COVERS MUST BE USED FOR ON-THE-PLATE REGENERATION.

There are several auxiliary functions available through the use of the Chef Function Key.

With the exception of the ability to add additional moisture to the oven compartment, that

an only be used during the convection mode, all additional functions can be engaged at any time during any

At the end of a cooking mode or program, the oven automatically disengages all operator-set chef functions. These functions, however, do remain programmed and will reengage the next time the programmed procedure is used.
