Detail Information

                    Liquid Nitrogen iqf freezer machine 300kg/h 

Liquid nitrogen temperatures can reach minus -190 ℃ 

When it is in contact with food,Gasification will be able to take heat away more quickly.

The ultra-low temperature and high heat exchange rate achieve a really quick frozen.
Such rapid freezing,generating the smallest ice crystals, and helps maintain food texture.This also prevents water loss, and almost no loss:to maintain the original color,flavor and original quality of the food.
These vaporized refrigerant nitrogen is directed to the front end of the refrigerating machine uniformly,complete the exchange of hot inverse,thereby improving the utilization of the nitrogen.
Liquid nitrogen quick freezing machine is suitable for food with high value, such as cooked wheaten food fish,shrimp, roe, abalone and so on.
  1. Maximum speed of decreasing temperature ―― ≥ 50 ℃ /min;
  2. Maximum speed of increasing temperature ―― ≥ 8 ℃ /min (used for defrost or sterilization at high temperature);
  3. Accuracy of temperature control ―― ±3 ℃;
  4. Uniformity of temperature ―― ±1 ℃;
  5. Advantage:
1.  No damage of cell structure, no dehydration and dry loss,no moisture loss.
2.  Improve productivity, improve texture, color, flavor of frozen product.
3. The nitrogen freezer is Environmental, no pollution, no noise.
4. Easy to operate and easy to repair, don't need special technician.
5. All stainless steel SUS304 structure parts
6. Higher quality of the frozen product compared with slower methods

2. Main structure and configuration

The equipment is a continuous production lineSafe and durableEasy operation. Quick freezing machine mainly by the body, insulation system, transmission system, refrigeration system, control system 

Body and thermal insulation system

Body design:The thickness of the inner cavity and the outer cavity is 2MM sus304 food grade stainless steel plate shearing and bending.The position of the force with the reinforcement and reinforcement of TeflonTo ensure long-term bearing does not deformMake the craft beautiful.   

Integrated electric cabinetSave space.

Thermal insulation layerGermany imported BASF polyester raw materials.Multi layer thermal insulation foam insulation layer, insulation layer thickness: 150mm

Equipment maintenanceAdopt integral lifting systemEasy to clean and maintain the conveyor beltThe bottom of the body with drain outIn order to discharge equipment to clean waste residue and waterDesign of equipment with long life and low consumptionSimple and rapid replacement of vulnerable partsExcellent maintainability.Lifting screw material is SUS304.

Transfer system

Food transportationSUS304 food special conveyor beltWith variable frequency adjustable speed motorConveying speed can be adjusted according to different productsThe device is also provided with a mesh belt tightness adjusting deviceTo ensure the stable and long life of the food conveyor belt

Variable frequency motor and speed reducerAdjustable speed

Conveyor belt is stainless steel 304 chain plate mesh beltCorrosion resistance and low temperature resistanceCan be used for a long time.

Refrigeration system

Liquid nitrogen flow control solenoid valve KEIHIN solenoid valve with manual liquid nitrogen stop valve joint control, equipped with redundant systems, in which a group of faults, but also normal production, to ensure adequate safety

 

A series of stainless steel nozzles formed in liquid nitrogen quick freezing zone formed a uniform and stable liquid nitrogen cold flow, and the nozzle has a long life without damage.The conveyor belt is equipped with a spray deviceAutomatic manual operationCan open all the work can also open the work independently.The upper and lower spray angle can be adjusted, so that the speed of product production more uniform effect

Low temperature long axis motor and aluminum alloy axial fanIn the air cooling mode, it can guarantee the fast convection cooling, at the same time, it can ensure the uniform temperature field and the fan speed can be adjusted.Fan blade angle can be adjusted manually according to different products

Liquid nitrogen transfer tubeLow temperature high pressure liquid nitrogen conveying pipeThe outer layer is treated by heat preservationNot easily damagedCan effectively reduce the loss of liquid nitrogen

The feed end and the discharge end are provided with a tail gas outlet, which is connected with a large flow frequency conversion fan, and the tail gas of the quick freezing line can be drawn out to the designated position for discharging or pre cooling material

Control system

The control system has two kinds of automatic and manual refrigeration mode, the user can choose according to the different production needs

With the running speed of the network, the fan speed can be adjusted by frequency conversion, matching the different temperature to adapt to different frozen categories

The use of man-machine interface (touch screen) input, PLC intelligent control, with PID automatic adjustment function, can be divided into ten steps to cool and heat preservation, automatic alarm after the end of all procedures

PT100 platinum resistance temperature measurementMeasuring range200℃-200℃

SIEMENS 10 inch color screenManual and automatic operationInput is intuitive and simple.Can store a variety of refrigeration technology, one button operation.

Contactor, button: all imported Schneider components, reliable and durable

Belt drive system is equipped with independent frequency conversion motor

At the discharge end of the equipment, the receiving end of the electric cabinet is equipped with emergency stop safety switch to ensure the safety of different stations at any time
