Cost-Effective Liquid Nitrogen Quick-Freezing Machine For Fish/Shrimp/Fruit/Vegetables/Foods
Product description
DJL liquid nitrogen cabinet iqf freezer for foods has a fast freezing speed (passes the largest ice crystal growth zone within 30 minutes, the center temperature drops below -5℃, and the diameter of the ice crystals formed is less than 100um) , great freezing effect ( No damage to the cell wall, without losing tissue fluid, maintaining the original color, flavor and quality of food), it is suitable for small and medium batch production, widely used in factories, hospitals, schools and other catering places. Small footprint.
The style change of Cost-Effective Liquid Nitrogen Quick-Freezing Machine For Fish/Shrimp/Fruit/Vegetables/Foods
-Single-door cabinet freezer: Applicable to individual quick-freezing (IQF) and tray freezing. It is suitable for internal testing,developing and small-lot production. Small land occupation and low energy consumption.
-Double-door cabinet freezer: It is composed of two boxes, each box can be controlled separately, work alone, convenient for the situation that the quick-frozen food quantity is not full, only need to start one box to work, save the cost of liquid nitrogen. If two boxes are used at the same time, the exhaust gas can be used to precool each other.
-Multi-door cabinet freezer: It is composed of multiple boxes, each box can be controlled separately, work alone, If multiple boxes are used at the same time, the exhaust gas can be used to precool each other.
-Laboratory cabinet freezer: Commonly used in scientific research sites of schools and companies.

FAQ:
1, What is the refrigerant of DJL liquid nitrogen freezer? Is it safe? Do I need to go through any special procedures?
DJL Reply: The refrigerant used in the DJL liquid nitrogen freezer is liquid nitrogen. Liquid nitrogen is separated from the air by cryogenic air separation technology. It is neutral and non-combustible and non-explosive. However, high concentration of nitrogen should be prevented from causing oxygen deprivation in confined Spaces; In addition, the limbs should not be placed in low temperature for a long time, nor can the limbs be immersed in liquid nitrogen, which will cause frostbite. Relative to others, liquid nitrogen is a relatively safe refrigerant.
It should be noted that when liquid nitrogen storage tank is used, it shall be submitted for approval for filing, which can be generally handled by the liquid nitrogen supplier.
2, What is the dry consumption of liquid nitrogen quick freezing?
DJL Reply: For seafood naked freezing with high water content, after froze by DJL liquid nitrogen freezing technology, its dry consumption is about 1‰ to 5‰, while the traditional freezing method is generally within 3~5% . If the product with a relatively high unit price, alarge part of the loss of economic value can be avoided by dry consumption weight.
3, Is the purchase cost of liquid nitrogen freezer high? How long can it be used? What are the special requirements for supporting resources?
DJL Reply: Under the same output, the purchase cost of DJL liquid nitrogen freezer is about one-half of that of the compressor iqf freezer. Due to different refrigeration methods and structural design, its service life can be up to 20 years, about twice as long as the traditional equipment. Liquid nitrogen quick freezer mainly depends on liquid nitrogen refrigeration, the need for electricity is relatively low, power distribution mainly is for the convection fan and transmission system, generally, it is one-tenth of the compressor quick-freezing equipment with the same capacity.
