SECTION 1 DESCRIPTION

II. PRINCIPLE OF AIR FLOW

Air is heated and then pulled through the fan which pushes the air into the oven plenum and delivers heated air into the air fingers. The fingers contain an inner plate and outer plate which columnate the air and evenly distribute heated air across the conveyor belt on which the product rides. Air is then pulled back into the blower and the process continues.

A. Heat Transfer and How It Works

1. Heat constantly moves from a warm object to a cold object. Heat moves using three different paths which are conduction, radiation and convection.

Conduction:

tact. The pizza dough in contact with the pan is a good example of conduction.

Radiation:

heat. Dark objects absorb heat whereas light or shiny objects reflect more heat. This is the reason that the

This path utilizes surface to surface con-

This path has to do with objects radiating

inside of the Middleby Series PS200-R68 Oven is light in color to reflect more heat back to the product.

Convection:

of air. It explains why hot air will rise and cooler air replaces hot air. An industrial application of this principle is to incorporate a fan to force the hot air movement which in turn will increase the heat transfer to the product.

The Middleby Series PS200-R68 Oven has a large fan to move the hot air through the air fingers and onto the product so the most efficient bake is achieved.

2. Temperature is the intensity of heat at the point which it is sensed. As discussed above, heat flows by conduction, radiation and convection. The speed at which the heat flows is determined by the temperature difference between the oven and the food product. The larger the difference the faster the heat flows to the item that is being baked.

This path has to do with moving amounts

B. Air Fingers

The Middleby Series PS200-R68 Oven is a conveyorized hot air oven employing vertical air streams (Figure1-3) to give uniform and intensive heating. The columnated vertical streams of hot air provide an exceptional heat transfer rate and generally bake faster and at lower temperatures than convection hot air or infrared heating ovens.

Outer Plate

Manifold

This is accomplished with use of hot air fingers inside the oven. The oven can accommodate up to 4 bottom air fingers and 4 top air fingers. Standard PS200-R68 Series ovens have 4 bottom fingers and 2 top fingers.

III. COMPONENT FUNCTION

A. Conveyor

The conveyor is driven by a variable speed electric motor operating through a gear reducer (See Figure 1-5). The motor speed is controlled by a digital control. The stainless steel wire belt can travel in either direction and at variable speeds from 3 minutes to 23 minutes.

Drive Motor

Fan

Should a flame outage occur the control will close the main gas control valve within 0.8 seconds and attempt to reignite the pilot.

D. Electric Heaters (Electric Oven Only)

There are six heater elements mounted on the inside of the rear panel. Each element is connected to a separate electrical contact which is energized by the temperature controller.

E. Front Window

The front window is used for viewing items being baked and provides access to the oven for items which do not require full bake time, such as sandwiches, cookies, small items or cheese melting processes.

F. Cooling Fan

A cooling fan is located in the back of the oven. This cooling fan blows cool air in through the machinery compartment across the fan motor and conveyor motor and control cabinet. The air is then exhausted through the side of the cabinet and also out the back of the oven compartment. Refer to Figure 1-6.

Main Gas

Control Valve

Figure 1-5. Conveyor Drive Motor

B. Fan

The fan is located at the rear of the oven. This fan forces heated air through the fingers. The fan switch has two positions and must be "on" for oven warm up and bake and for the conveyor to run.

Another cooling fan is located in the bottom of each control box. Air is drawn in through the louvers in the rear of the control box and out through the fan. Refer to Figure 1-4.

C. Gas Burner (Gas Oven Only)

With the heat and blower switches ON the gas burner heats the air as the air enters the main blowers to maintain the set temperature. The burner flame is ignited and monitored by a solid state burner control device.

SECTION 1 DESCRIPTION

G. Air Fingers

The Air Finger Assemblies are made up of three parts as follows (See Figure 1-7):

1. Outer Plate - The Outer Plate is the removable cover with tapered holes, which directs the air stream onto the product to be baked.

2. Inner Plate -The Inner Plate is vital to forming the

manifold with its holes lined up with outer plate holes. The inner plate is also manufactured with no rows of

holes. This type of finger is a non-columnating air finger.

3. Manifold - The Manifold is the assembly which slides on tracks into the oven plenum.

4. Blank Plates- The Blank Plates are installed on the plenum where air fingers are not required.

V. VENTILATION GUIDELINES

A mechanically driven ventilation system is required for the PS200-R68 Series Middleby Marshall conveyorized gas ovens. The minimum hood canopy dimensions are outlined below.

Local codes and conditions vary greatly from one area to another and must be complied with. These are the “Authority having jurisdiction” as stated by the National Fire Protection Association, Inc. in NFPA 96-latest edition. Following are the suggested requirements for good ventilation. Please remember these are general recommendations or guidelines, you may have a special condition or problem that will require the services of a ventilation engineer or specialist. Proper ventilation is the oven owner’s responsibility. Improper ventilation can inhibit oven performance. It is recommended that the ventilation and duct work be checked every three months.

Grease filters in the intake of the hood may be required by local codes.

VENTILATION HOOD The rate of air flow exhausted through the ventilation

system is generally between 1400 and 2500 CFM, but may vary depending on the oven configuration and hood design. To avoid a negative pressure condition in the kitchen area, return air must be brought back to replenish the air that was exhausted. A negative pressure in the kitchen can cause heat related problems to the oven components as if there were no ventilation at all. The best method of supplying return air is through the heating, ventilation and air conditioning system (HVAC). Through the HVAC system, the air can be temperature controlled

for summer and winter. Return air can be brought in directly from outside the building, but detrimental affects can result from either extreme seasonal hot and cold temperature from the outdoors.

NOTE: Return air from fan driven system within the hood must not blow at opening of bake chamber or poor oven baking performance will result.

VENTILATION CAPTURE TEST It is recommended that a 30 second smoke candle test be

performed on your ventilation hood system. Follow the steps below to complete the ventilation smoke test.

All tests are to be done on single ovens or lower units of a double oven. We recommend you wear protective gloves when performing this test. At no time should food be present when the smoke test is being conducted. Also check that no fire suppression system will be activated by the smoke.

1. Turn ventilation system on.

2. Turn oven(s) on and allow to heat up to customers normal operating temperature, or a minimum of 480°F (248°C).

3. Turn conveyor off. Place a 30 second smoke candle in a pie or cake pan which is no higher than 3" (76mm).

4. Open the front oven window. Next, light the smoke candle in the pan and then slide the pan into the center of the bake chamber on the conveyor belt and close the window.

5. The ventilation hood should capture 90% to 100% of the smoke produced by the candle.

VI. ELECTRIC SUPPLY FOR GAS HEATED OVENS

Electric supply for all gas heated ovens is 208-240 volts AC single phase. Each oven requires a separate 15 amp service. Connection is made as shown in Figures 2-8 & 2-12. A separate ground wire must also be supplied.

CAUTION: Before connecting incoming power to oven, a voltage reading of each leg to neutral must be made. These readings should not normally exceed 120 volts each.

If one of the incoming legs reads over 130 volts, this indicates the supply voltage has a high leg.

Export ovens are supplied with a stepdown transformer for the 110V control circuit.

Call your local electrician or electrical power supply company and have them remove the high leg from the electrical supply line for the oven.

Connecting a high leg to the black lead of the oven will severely damage many of the electrical components in the oven.

CONNECTING A HIGH LEG TO THE BLACK WIRE VOIDS ALL OVEN WARRANTIES.

Connect one 208-240V supply leg to the black wire and the other 208-240V supply leg to the red wire. The supply neutral should connect to the white oven wire and supply ground should connect to the oven ground screw located in the main junction box.

VII. ELECTRICAL CONNECTION INFORMATION FOR ALL OVENS.

Check the oven data plate before making any electrical connections. Connections must agree with data on oven data plate (Refer below to Figure 2-11).

NOTE: In Canada with C22.1,Part 1 and/or local code.

A fused disconnect switch or circuit breaker (not furnished) MUST be installed in the electrical supply line FOR EACH OVEN. A lockout/tagout electrical shutoff must be installed for each oven, refer to Figure 2-9. The service connection must meet all national and local electrical code requirements. All connections are made at one common connection at the back of each control box.

NOTE:

When the oven is installed it must be electrically

grounded in accordance with local codes, or in the

absence of local codes. ANSI/NFPA - Latest edition.
