Introduction

The Blodgett CombiĆOven/Steamer

For quite some time, commercial cooking equipĆ ment has remained more or less unchanged. There are kettles, deck ovens, the good old range with its legion of pots āand āmany āother āextra āappliances. The result: time expenditure, excesĆ sive manual work, and countless cleaning proĆ cesses. The last āāāfew āāāyears āāhave āāpaved āāthe āāway āāfor āa revolution in the equipment of restaurant and inĆ stitutional kitchens.

The Blodgett CombiĆOven/Steamer offers a comĆ pletely new method of cooking. With the Oven/ Steamer you have the choice of two cooking proĆ cesses: 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

Not āāonly āāthat, āāyou āācan āāuse āātwo āāor āthree functions in sequence during one cooking process. We call this:

D combiĆsteaming D combiĆroasting D combiĆbaking

The combination of circulating hot air and steam in the space saving, high performance CombiĆ Oven/Steamer leads to improvements in the folĆ lowing areas:

D increased productivity in the kitchen D a 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 āpans āand trays. Food can be cooked, stored, and transported with āthe āsame āāpans. āSmall āamounts of product can be processed efficiently; preĆcooked and conveĆ nience foods can be reheated within minutes. āMany frozen foods can be processed without preĆ thawing. 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 imĆ portant than ever. Vegetables are cooked in the Blodgett CombiĆOven/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 CombiĆOven/Steamer is being used more and more for baking. Steam and Hot āAir āmodes āmake āit āa āgeneral āpurpose baking appliance.

The COSĆ20 model includes a built in steam genĆ erator. This unit includes an inlet, funnel assembly and valve lever for decalcification.

Introduction

Description of the CombiĆOven/Steamer

ABOUT THE OVEN/STEAMER

Blodgett CombiĆOven/Steamers are quality proĆ duced using highĆgrade stainless steel with first class workmanship.

The use of high quality insulation impedes excesĆ sive heat radiation and saves energy.

The high performance steam 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 circuĆ lated at high speed. This process enables quick and gentle cooking and ensures high quality product while providing convenient working methods.

A patented quench system keeps the air in the unit clean. Fumes are extracted from the appliance, quenched, and directed out through the condensĆ er drain. The exhaust system is effective in all cooking modes and results in better quality foods and no flavor transfer. The 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. CondensaĆ tion and waste water, which result during steamĆ ing and cleaning, are continuously drained.

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 simĆ ple arrangement of the controls. Graphic symbols make the appliances easy for even inexperienced kitchen staff to operate. All modes can be selected with one switch. This includes the Cool Down mode, which allows the oven cavity to cool down rapidly with the door opened or closed.

Cleaning is kept to a minimum. The interior can be sprayed with a cleaning solution 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 cleaning process.

Location and Ventilation

LOCATION

The well planned and proper placement of your appliance will result in long term operator conveĆ nience and satisfactory performance.

The following clearances must be maintained beĆ tween the unit and any combustible or nonĆcomĆ bustible construction.

COSĆ20E

D Right side of unit - 1" (2.5 cm) D Left side of unit - 4" (10 cm) D Back of unit - 6" (15 cm)

The following clearances are recommended, but not required, for servicing.

D Left side of unit - 12" (30 cm) D Back of unit - 12" (30 cm)

Place the unit in an area which is free of drafts and accessible for proper operation and servicing.

Keep the operating area free and clear of all comĆ bustibles such as paper, cardboard, and flamĆ mable liquids and solvents.

DO NOT place the unit on a curb base or seal to the wall; either condition will prevent proper ventiĆ lation to the blower motors. Slight unevenness can be corrected with the adjustable legs.

Heat sources should not be located near the air vents on the left hand side of the unit. Consult the factory for an optional protective side heat shield kit, P/N R9050, if a warm surface or water source is to the left of the unit.

Tripping the blower motor's thermal overload deĆ vice indicates an excessive ambient temperature on the side of the oven. This must be corrected to prevent permanent damage to the oven. All motor bearings are permanently lubricated by the manĆ ufacturer; there is no need for additional lubricaĆ tion during the operational lifetime of the motors.

VENTILATION

The necessity for a properly designed and inĆ stalled ventilation system cannot be over emphaĆ sized. The ventilation system will allow the unit to function properly while removing unwanted vaĆ pors and products of combustion from the operatĆ ing area.

The appliance must be vented with a properly deĆ signed mechanically driven exhaust hood. The hood should be sized to completely cover the equipment plus an overhang of at least 6" (15 cm) on all sides not adjacent to a wall. The capacity of the hood should be sized appropriately and proviĆ sions made for adequate makeup air.

WARNING!! Failure to properly vent the oven can be

hazardous to the health of the operator; and will result in operational problems, unsatisfactory baking, and possible damĆ age to the equipment. Damage sustained as a direct result of improper ventilation will not be covered by the Manufacturer's warranty.

When installed in the Commonwealth of MassaĆ chusetts, this appliance must be interlocked with the hood exhaust system so that the appliance may be operated only when the hood exhaust sysĆ tem is running.
