Introduction |
The Blodgett Combi-Oven/Steamer
The Blodgett Combi-Oven/Steamer offers a completely new method of cooking. With the Oven/ Steamer you have the choice of two cooking processes: Steam and Hot Air, either...
D Separately
D Combined, or D In Sequence
And for easy operation you can choose from three modes:
Steam |
Hot Air |
Combi |
Steam &
Hot Air
In the Steam mode you can:
steam |
reheat |
reconstitute |
stew |
thaw |
simmer |
blanch |
preserve |
braise |
poach |
|
|
In the Hot Air mode you can: |
|
|
roast |
bake |
|
grill |
gratinate |
|
broil |
|
|
In the Combination Steam and Hot Air mode you can:
defrost |
roast |
rethermalize |
reheat |
bake |
forced steaming |
You can also use two or three functions in sequence during one cooking process. We call this:
D combi-steaming D combi-roasting D combi-baking
The combination of circulating hot air and steam in the space saving, high performance CombiOven/Steamer leads to improvements in the following areas:
D increased productivity in the kitchen
Da reduction in capital expenditures for multiple equipment replacement
D a wider range of menu choices D a simplified cleaning process
The work process is simplified since products are prepared on or in steam table pans and trays. Food can be cooked, stored, and transported with the same pans. Small amounts of product can be processed efficiently; pre-cooked and convenience foods can be reheated within minutes. Many frozen foods can be processed without prethawing. This flexibility in preparation reduces the need for kettles and steam tables since there is no need for large amounts of food to be kept warm for long periods of time.
Today the improvement of food quality is more important than ever. Vegetables are cooked in the Blodgett Combi-Oven/Steamer without water at the optimal temperature of just under 100_C (212_F), maintaining valuable vitamins, minerals, nutrients and trace elements. Cooking meat in the Combi results in less shrinkage and a firmer, juicier product. The Blodgett Combi-Oven/Steamer is being used more and more for baking. Steam and Hot Air modes make it a general purpose baking appliance.

Introduction
Description of the Combi-Oven/Steamer
ABOUT THE OVEN/STEAMER
Blodgett Combi-Oven/Steamers are quality produced using high-grade stainless steel with first class workmanship.
The two speed fan, which is guarded against accidental finger contact, is driven by a quiet and powerful motor. The condenser draws out excess steam from the appliance. Condensation and waste water, which result during steaming and cleaning, are continuously drained.
The use of high quality insulation impedes excessive heat radiation and saves energy.
The high performance fresh steam generator with its control system makes it possible to enjoy all of the advantages of a high quality steamer at the flick of a switch. Fresh steam enters the oven cavity without pressure and is circulated at high speed. This process enables quick and gentle cooking and ensures high quality food while providing convenient working methods. The steam generator is completely automatic and protected from running dry.
OVEN/STEAMER OPERATION
The practical oven door, with a viewing window, has a wide swing radius and handle which can be operated easily, even with wet or greasy hands.
Ease of operation is guaranteed through the simple arrangement of the controls. Graphic symbols make the appliance easy for even inexperienced kitchen staff to operate. Steam, Hot Air and Combi modes can be selected with one switch. The Steam On Demand feature allows the operator to add steam at any time for up to 8 minutes while operating in either the hot air or Combi modes. This feature is excellent for baking as well as roasting operations. A fourth function on the mode selection switch, the Cool Down mode, allows the oven cavity to cool down rapidly with the door opened.
The steam on demand function allows the operator the ability to introduce steam into the cooking process at any time.
Cleaning is kept to a minimum. The interior is sprayed with a self-acting cleaning solution which interacts with steam to easily remove crusts and stains. The oven is designed for easy care and is welded water tight so that the internal cooking cavity may be rinsed with a hose after the steam cleaning process.

Installation
Gas Connections
GAS PIPING
A properly sized gas supply system is essential for maximum oven performance. Piping should be sized to provide a supply of gas sufficient to meet the maximum demand of all appliances on the line without loss of pressure at the equipment.
Example:
NOTE: BTU values in the following example are for natural gas.
You purchase a BC-20G to add to your existing cook line.
1. Add the BTU rating of your current appliances.
Pitco Fryer |
120,000 |
BTU |
6 Burner Range |
60,000 |
BTU |
Deck Oven |
50,000 |
BTU |
Total |
230,000 |
BTU |
2.Add the BTU rating of the new oven to the total.
Previous Total |
230,000 BTU |
BC-20G (for hot air) |
125,000 BTU |
New Total |
355,000 BTU |
3.Measure the distance from the gas meter to the cook line. This is the pipe length. Let’s say the pipe length is 20’ (6 m) and the pipe size is 1” (2.54 cm).
4.Use the appropriate table to determine the total capacity of your current gas piping.
The total capacity for this example is 465,000 BTU. Since the total required gas pressure, 355,000 BTU is less than 465,000 BTU, the current gas piping will not have to be increased.
NOTE: The BTU capacities given in the tables are for straight pipe lengths only. Any elbows or other fittings will decrease pipe capacities. For example: a schedule 40-1/2” elbow fitting has an equivalent cpapacity of 4.2” (10.2 cm) of straight pipe. Contact your local gas supplier if you have any questions.

PRESSURE REGULATION AND TESTING
The gas pressure to the appliance must be rated for each appliance while the burners are on. A sufficient gas pressure must be present at the inlet to satisfy these conditions. Refer to the table below for correct gas pressure.
Each appliance has been adjusted at the factory to operate with the type of gas specified on the rating plate attached to the right side of the appliance.
Each oven is supplied with a regulator to maintain the proper gas pressure. The regulator is essential to the proper operation of the oven and should not be removed.
DO NOT INSTALL AN ADDITIONAL REGULATOR WHERE THE UNIT CONNECTS TO THE GAS SUPPLY UNLESS THE INLET PRESSURE IS GREATER THAN 14” W.C. (1/2 PSI) (37mbar).
The oven and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.45kPa).
The oven must be isolated from the gas supply piping system by closing its individual manual
shutoff valve during any pressure testing of the gas piping system at test pressures equal or less than 1/2 psig (3.45kPa).
