Detail Information

Liquid nitrogen tunnel freezer Product description
Liquid nitrogen temperatures can reach minus -190ºC. When it is in contact with food,Gas ification will be able to take heat away more quickly.

The ultra-low temperature and high heat exchange rate achieve a really quick frozen.

Such repid 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 ―― ≥ 50ºC/min;

2.Maximum speed of increasing temperature ―― ≥ 8ºC/min (used for defrost or sterilization at high temperature);

3.Accuracy of temperature control ―― ±3ºC;

4.Uniformity of temperature ―― ±1ºC;

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 line，Safe and durable，Easy 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 Teflon，To ensure long-term bearing does not deform，Make the craft beautiful.
Integrated electric cabinet，Save space.
Thermal insulation layer：Germany imported BASF polyester raw materials.Multi layer thermal insulation foam insulation layer, insulation layer thickness: 150mm
Equipment maintenance：Adopt integral lifting system，Easy to clean and maintain the conveyor beltThe bottom of the body with drain out，In order to discharge equipment to clean waste residue and water；Design of equipment with long life and low consumption，Simple and rapid replacement of vulnerable parts，Excellent maintainability.Lifting screw material is SUS304.
Transfer system	Food transportation： SUS304 food special conveyor belt，With variable frequency adjustable speed motor，Conveying speed can be adjusted according to different products；The device is also provided with a mesh belt tightness adjusting device，To ensure the stable and long life of the food conveyor belt
	Variable frequency motor and speed reducer，Adjustable speed。
	Conveyor belt is stainless steel 304 chain plate mesh belt，Corrosion resistance and low temperature resistance，Can 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 device，Automatic manual operation，Can 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 fan，In 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 tube：Low temperature high pressure liquid nitrogen conveying pipe，The outer layer is treated by heat preservation，Not easily damaged，Can 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 measurement，Measuring range：200℃～-200℃。
	SIEMENS 10 inch color screen，Manual and automatic operation，Input is intuitive and simple.Can store a variety of refrigeration technology, one button operation.
