Description:

Liquid nitrogen quick freezer

1. Composition of equipment:
The main body of U equipment, including box body, door and insulation layer, is made of AISI 304 stainless steel.

U Inner Surface Roughness - Wire Drawing Treatment;

U insulation material-insulation layer is a multi-layer composite structure of ultra-low temperature insulation material in Basf, Germany; double-sided stainless steel polyurethane foams under high pressure, with good thermal insulation performance and easy cleaning
To ensure food hygiene and safety, and to avoid excessive reproduction and breeding of microorganisms.

U door body seal - double seals, special low temperature resistant silicone rubber imported from France, door seals are equipped with anti-freeze heating system to ensure that the door opens freely.

The reinforced U box can reliably bear the weight of the workpiece. The special design can make the wind direction and air flow in the box unobstructed to ensure that the temperature in the box is consistent.

U Introduced HACCP concept of health and safety, all stainless steel internal structure and enclosure structure fully considered for easy cleaning, maintenance, management, easy to operate, fully satisfiedHygienic and safety requirements of food for equipment.

U Reasonable overhaul door and overhaul passage for easy overhaul and internal cleaning

U uses hydration frost to ensure the cleanliness and hygiene of liquid nitrogen atomization system and avoid bacterial reproduction.

U tray-type pull-and-place mode makes it easier to enter and exit materials.

U food grade stainless steel cabinet body is suitable for processing of various articles.

The bottom of U is inclined at a certain angle, and the height can be adjusted. An open and closed drainage device is installed to facilitate the drainage of the system and ensure the sanitation and cleanliness of the equipment.

Efficient cleaning device, hygienic and safe. The internal structure of easy cleaning and the necessary check-in door are designed to ensure the internal cleaning and food hygiene safety and prevent pollution.

U adopts fully enclosed structure, with wind field pressure balancing device at the inlet and outlet ends to prevent the leakage of cold air, and the energy saving effect is obvious.


2.Technical parameters:

U Quick-freezing amount - 100Kg-1000Kg/1h;

U pallet size - see below parameters

The working temperature of U - room temperature to - 190 can be set at will.

The lowest temperature in the U box is (- 190 C);

Precision of U temperature control - heating, cooling, constant temperature (+3 C);

Uniformity of U temperature field -+3 C;

U insulation layer thickness - 120 mm, to ensure that the equipment at high and low temperatures outside the surface temperature is normal temperature;

U liquid nitrogen system, including adiabatic pipe, control valve, nozzle and distributor, uses multi-point injection of liquid nitrogen to ensure the uniformity of well temperature.

The air circulation system in U box includes motor, fan and air distribution device.

U micro-pressure relief valve - when the chamber pressure is micro-positive, the valve will automatically discharge;

U electrical control system - variable program controller, touch screen, PLC, alarm instrument AC contactor, intermediate relay, knob switch, etc.


3. Installation parameters:

U power - 380V, 50Hz, 0.55kw;

U Equipment Outward Size - See the following parameters

IV. Composition of liquid nitrogen system:

U liquid nitrogen system - adiabatic pipe, control valve, nozzle, distributor, liquid nitrogen is injected by multi-point injection to ensure the uniformity of well temperature;

U liquid nitrogen solenoid valve - imported from Germany) ultra-low temperature solenoid valve can ensure normal opening at - 196 C.

U liquid nitrogen nozzles - liquid nitrogen nozzles consisting of hundreds of micropores, which fully gasify liquid nitrogen. The gasified nitrogen sprays out from the nozzles and does not directly spray to frozen articles.And circulate in the box, so that the atmosphere in the box is uniform.

The special high efficiency and low noise axial flow fan for U quick freezing has the advantages of short return air distance, fast freezing speed and 85% higher efficiency than the ordinary freezing method.

Unique wind field design makes the wind speed and temperature in the quick-frozen zone more uniform and stable, reduces the resistance loss of the duct to the air flow, reduces the power of the fan and reduces the cooling capacity.
