21. Transmission system adopts double pitch chain transmission device, with a famous reducer, frequency converter to ensure transmission system is stable and reliable, and prevent the mesh belt deviation and skip chain special design

21. Food grade stainless steel mesh belt, chain drive mechanism, high strength chain, sprocket, not easy to wear, long life, good elasticity, strength. Imported frequency conversion speed regulation, quick freezing time can be adjusted according to different items, to adapt to the processing of a variety of items
21. Mesh belt mechanism with locking structure adjustment, automatic repair device, prevent the mesh belt deviation and relaxation, improve the network with a smooth running of, prolong the service life
21. Bottom tilt angle, adjustable height, set up with open and close drainage device, easy to system drainage and sanitation
21. High efficiency cleaning device, health and safety. The design of the internal structure of easy cleaning and inspection doors must be, to ensure the internal cleaning and food hygiene and safety, pollution prevention

21. With fully enclosed structure, Inlet and outlet end is set with the wind field pressure balancing device, which is used to prevent the air leakage, and the energy saving effect is obvious.

21. Frozen capacity——2000Kg/1h
21. Working  temperature——+121℃～-150℃（can be set arbitrarily）
21. Lowest temperature in the box――≤-150℃
21. Maximum cooling rate—— ≥ 20℃/min；

21. Maximum heating rate—— ≥ 8℃/min(the use of Defrosting or High temperature sterilization)
21. Accuracy of temperature control——±3℃
21. Temperature uniformity——±3℃
21. Insulation layer thickness —— 150mm, to ensure that the surface temperature is normal whether the equipment is in high or low temperature
21. The liquid nitrogen system——including the heat insulating tube, the control valve, the nozzle, the distributor. And the liquid nitrogen is injected by multi point injection, ensure the uniformity of the temperature of the well.

21. The inside air circulation system —— including motor, fan, air distribution device
21. Micro pressure valve —— When the pressure of the cavity reaches the micro positive pressure, the valve will automatically discharge

21. Electrical control system —— the variable process controller, touch screen, PLC, alarm instrument AC contactor, intermediate relay, knob switch, etc.;

21. Power -- 380V or 220V, 50Hz, 8.92kw
21. Dimensions -- 15000mm * 2000mm * 1800mm;
21. The effective size ( conveyor belt dimensions ) -- 15000mm * 1500mm

21. Liquid nitrogen system —— including the liquid nitrogen tank (customer or optional), booster system, heat insulation pipe, control valve, nozzle, distributor, liquid nitrogen injection to ensure the uniformity of the well body temperature;
21. The liquid nitrogen solenoid valve (ASCO USA electromagnetic valve -- imported) cryogenic solenoid valve to ensure the normal opening in -196 ℃;
21. liquid nitrogen nozzle —— used by hundreds of microporous consisting of liquid nitrogen spray nozzle, liquid nitrogen sufficient gasification, gasification of nitrogen ejected from the nozzle, do not spray directly to  frozen goods, but cycle in the box, to make the atmosphere in the chamber even;
21. frozen dedicated and efficient low noise axial flow fan, return short distance, quick freezing speed, efficiency than ordinary freezing improve 40%-65%,

21. There is a unique wind farm design to make sure the wind speed and temperature of the frozen region more uniform and stable, reduce air duct on the flow resistance loss, reducing the power of the fan, reduces the consumption of cooling capacity.

21. This system uses the touch screen+PLC                                                                  control mode, the touch screen or computer as the upper computer, PLC as the lower machine, make the operation and quick freezing process more convenient, and can real-time monitor the temperature change in the frozen box, and can observe the process operation, set the curve and running curve to compare.
21. The alarm device is set, we will be alarmed when the door is not closed.
21. The system has the function of manual and automatic two sets, the touch screen can be reflected, simple operation, high reliability. The high and low temperature control of the two system are adopted PID regulation, so that the accuracy of the equipment meet the requirements of the tender.
21. Operating system -- the whole English operating system; the pre freezing process, no operation after the start, the system will automatically be carried out in accordance with the process of cooling, heat preservation, getting out of the box and other actions;
