SECTION 2GENERAL DESCRIPTION AND

SPECIFICATIONS

1. GENERAL DESCRIPTIONThe Model 3072C Hot Water Shrink Tunnel is designed and manufactured by CRYOVAC spe-cifically to be used with CRYOVAC Stretch/Shrink Film to shrink overwrapped film on trayedmeat products, such as poultry and pork. The machine is one part of a total automatic systemused for leakproofing trayed meat products. The 3072C is precision-built of stainless steel andis designed to facilitate cleaning and provide many years of trouble-free operation.

Product enters the machine, via conveyor, as a sealed package. Hot water is pumped from asump to a bottom spray and top weir, where a uniform waterfall (curtain) is created. The pack-age is surrounded with hot water, which causes the film to shrink and tighten to the product.

Water in the machine is heated in the sump by a temperature-controlled steam coil. Steamflow into the sump coil is controlled by a Chromalox temperature controller, which opens andcloses an electric solenoid valve in the steam line. The temperature is adjusted using the diallocated in the temperature control box.

Water is circulated through the system by a motor-driven pump located underneath the ma-chine. The pump operates continuously when the pump switch is in the ON position.

The Model 3072C control box is equipped with three manual ON/OFF switches, allowing the op-erator to control the following machine functions:

• Conveyor (Drive)

• Pump

• Steam

The Model 3072C shrink tunnel has the following basic specifications:

• Conveyor speed: 60 feet per minute (fpm)

• Water temperature range: 170°F to 202°F

• Sump water capacity: 5 1/2 gallons (not including piping and weir box)

CAUTIONOPERATION OF THIS EQUIPMENT OUTSIDE THELIMITS OF THE SPECIFICATIONS SET FORTH IN

THIS MANUAL IS NOT RECOMMENDED.OPERATION OF THIS EQUIPMENT OUTSIDE THE

SPECIFIED LIMITS SHALL BE THE SOLERESPONSIBILITY OF THE USER.


2-1

1.1. Optional Blow-Off DeviceWhen the 3072C is equipped with the optional blow-off device, the 100 series designation isadded to the model number (3072C-100).

The blow-off device is a pneumatic component attached to the exit end of the unit. It uses con-trolled, compressed air blown across and around the packages exiting the tunnel to remove ex-cess water from the film.

The conveyor in the blow-off device is driven by the same motor that drives the shrink tunnelconveyor. As a package enters the blow-off device, it trips a pneumatic limit switch, which inturn activates a pneumatic valve that opens to allow compressed air through the piping systemand air nozzles.

The nozzles are aligned to ensure maximum air distribution around the package. The air con-tinues to blow the package dry as long as the limit switch is tripped. When the limit switch is re-leased flow through the valve ceases.

1. TEMPERATURE CONTROL ADJUSTMENTSRecommended operating temperature range is between 170°F and 202°F, as indicated on thetemperature gauge. Temperature settings are based on product size and the type of film beingused.

Note: Wait for the temperature to stabilize before making adjustments.

Rotating the temperature adjustment dial (located in the temperature control box) clockwise in-creases the operating temperature. Rotating the dial counterclockwise decreases the operat-ing temperature.

2. FLOAT VALVE SETTINGThis setting is fixed and is not adjustable. Water level in the sump is set at the factory to bemaintained 1/2 inch below the top of the overflow pipe.

3. STEAM PRESSURE SETTINGSThe tunnel is designed to operate at steam pressures between 8 and 15 psig. Pressures thatare too high or too low will directly affect the operating temperatures, which will in turn affectthe film-shrinking effectiveness of the machine.

Steam pressure (20 psig, maximum) is to be supplied by the customer. This pressure is thenreduced, via a pressure regulator, to between 8 and 15 psig for normal operation. Steam pres-sure is adjusted manually at the pressure regulator in the following manner:

Note: Do not make final adjustment to the steam system until the machine hasbeen in operation at least thirty (30) minutes.

1. Set the steam/water switch to the OFF position.

2. Open the customer-furnished steam supply valve and observe the pressure readingon the gauge.

Note: The pressure regulator is adjusted by loosening the locking jam nutlocated on top of the regulator, and rotating the hex-head screw clockwise ( toincrease pressure) or counterclockwise (to decrease pressure).

INDICATE THAT LIVE STEAM IS ESCAPING INTOTHE WATER. THIS MEANS THAT THE STEAM

PRESSURE IS TOO HIGH AND MUST BEREDUCED AT THE PRESSURE REGULATING

VALVE IMMEDIATELY.

3. With the machine in operation, set the steam/water switch to the ON position and ob-serve for bubbling in the sump water. Ideally, there would be no steam coming fromthe steam coil, because all of the steam should condense in the coil, thus releasingonly condensate.

4. Monitor the steam solenoid valve for ON/OFF cycles. If the valve cycles ON (opens)more than 50% of the operating time, increase the steam pressure by 2 psi at the pres-sure regulator. If the solenoid cycles OFF (closes) more than 50% of the operating, re-duce the pressure at the pressure regulator by 2 psi. Continue this procedure untiloptimum operation is achieved.

5. When pressure has to be decreased, first make the adjustment, then set thesteam/water switch to the ON position for twenty (20) seconds.

6. Set the steam/water switch to the OFF position to allow the pressure to stabilize.

7. Continuously monitor pressure leaving the pressure regulator.

Note: At times it may be necessary to momentarily open and close the ballvalve in order to allow trapped steam to escape. Repeat this action each timean adjustment is made to the valve until desired pressure is established.

8. Open and close the ball valve each time an adjustment is made to the pressure regula-tor. This releases trapped steam.

4. TOP WATERFALL ADJUSTMENTSThe top waterfall should be adjusted to flow uniformly and unbroken to ensure complete cover-age of the package.

Note: The bottom spray valve must be closed before performing the next step.

1. Partially open (1/2 to 3/4 open) the water control valve for the top weir box.

2. Loosen the appropriate screws and/or bolts on each side of the weir box to allow forproper adjustment.

3. Adjust the top weir box until the waterfall is uniform and unbroken.

4. Tighten all adjustment screws and/or bolts.

5. BOTTOM WATER SPRAY ADJUSTMENTSThe bottom water spray is factory-adjusted to flow slightly above the conveyor belt. To adjustthe bottom water spray:

1. Open the bottom spray water valve (1/2 to 3/4 open) and check that both the top wa-terfall and the bottom water spray provide proper coverage of the product.

2. Adjust the top waterfall and the bottom spray (starting with the waterfall) as necessaryto ensure adequate coverage of the product.

6. CONVEYOR TENSION ADJUSTMENTSUnder normal usage, the Flex-Grid conveyor belt will stretch slightly. Conveyor tension is ad-justed using the adjusting arm provided with the conveyor drive assembly. Always tighten thejam nuts after conveyor tension is correct.


5-2

CAUTIONDO NOT OVERTENSION THE CONVEYOR BELT.

THIS STRETCHES THE BELT EVEN FURTHER ANDCAUSES EXCESSIVE WEAR OF SPROCKETS AND

BEARINGS.

7. DAMPER DRAFT ADJUSTMENTSAdjust the damper to reduce the amount of vapor-laden air escaping into the processing area.Use the knurled screw at the vent stack to adjust the damper. Start with the damper closedand open it slowly until steam no longer escapes from the entrance and exit curtains. Alwaystighten the screw after proper draft is obtained.

Note: Opening the damper too much results in unnecessary heat loss andreduced operating efficiency.

8. BLOW-OFF NOZZLE ADJUSTMENTSTo adjust the direction of the air nozzles:

1. Loosen the swivel joint nut.

2. Align the nozzle by hand in the proper direction.

3. Tighten the swivel joint nut.

SECTION 6OPERATION

1. START-UPWhen the utility connections are complete and all valves are open, the following sequence ofsteps will put the machine into operation.

1. Close the sump drain valve.

2. Close the manual steam ball valve.

3. Open the manual water valve.

4. Set the steam/water switch to the ON position and allow the sump water to reach thepreset level (about 1/2 inch below overflow pipe).

5. Set the pump switch to the ON position.

6. Check the water flow from the top weir to ensure that the waterfall is uniform and un-broken.

7. Verify that the water is flowing correctly from the top weir, then open the steam valveto allow the steam to begin heating the water.

Note: Steam pressure must be set to operate at 8 to 15 psig.

8. Adjust the steam pressure regulator to 8 to 15 psig, depending on operating condi-tions.

Note: Temperature is regulated by adjusting the temperature control dial,located in the temperature control box. A clockwise adjustment increasestemperature, while a counterclockwise adjustment decreases temperature.

9. Adjust the temperature controller for the desired operating temperature (170°F to202°F) and allow ample time for the water temperature to stabilize.

10. Allow machine temperature to increase for about fifteen (15) minutes, and check thethermostat for accuracy.
