What is the operating principle of the double spiral quick freezer

First, the freezing plate containing frozen food is placed on the horizontal conveyor chain of the double spiral quick-freezer, the freezing plate the conveyor chain enter the lifting track of the freezer compartment together perform a step lifting movement. When the freezing plate rises to the position of the bridge frame, the push plate pushes the freezing plate to the lifting track on the lifting track, then the freezing plate the descending track run to the horizontal conveyor chain, the conveyor chain sends the freezing plate out of the refrigerator.

When the frozen product board is used in the quick-freezer to achieve the above process, the strong cold air generated by the refrigeration system forms a stable horizontal annular low-temperature air flow under the action of the fan the deflector, exchanges heat with the frozen food that moves vertically to realize the frozen food The rapid cooling freezing completes the freezing process.

All these processes are completed under the instructions of the "brain" of the refrigerator, the programmable controller (PLC) realizes human-computer interaction through the LCD touch screen. The main interface of the touch screen of the double spiral quick freezing machine is equipped with "automatic", "quick freezing time adjustment", "manual", "alarm", "status", "frosting", etc. The system starts enters the automatic operation state interface, the work instructions are issued by the "Start" "Stop" buttons on the touch screen.

The double-screw quick-freezer uses a spiral method to convey products, has a small area large freezing capacity, so this mechanism can produce a large number of quick-freezing equipment, it is currently used in many applications, mainly in the freezing industry of the food industry.

Operating Procedures of Double Spiral Quick Freezer:

1. Open the chain observe its operation. The speed slowly rises zero to zero, when it stops, the speed slowly returns high speed to zero.

2. Check the operation of each fan blade.

3. Turn on the fan observe the voltage.

4. Observe whether the frosting of the evaporator the number of ammeters are within the specified number.

5. Close the rear door, turn on the fan before cooling, open the chain, vibrate pulse, tell the ammonia compressor to start cooling.

6. When the temperature drops to the specified temperature, adjust the chain transfer to start work.

7. Observe the temperature product while working, adjust the chain speed at any time.

8. After the work is over, inform the ammonia compressor to stop cooling, turn off the fan vibration, open the front door the rear door close the chain.
