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.
DJL liquid nitrogen cabinet iqf freezer for foods is a high-efficiency freezing method using indirect injection for rapid freezing. The cold steam is recirculated through a recirculation fan. DJL liquid nitrogen cabinet iqf freezer for foods is also commonly referred to as batch freezer or laboratory freezer or blast freezer. Usually, a cart with several trays of product be put into the freezer and placed in it for a period of time. Since this is a batch process, it is ideal for applications that do not require linear or continuous processing along the development line. This may include smaller companies or product lines, test applications, and even schools and other buildings with canteens. It is applicable to freeze the fresh product, seafood, fish and shrimp, meat and poultry, out-of-season fruits, medicinal materials and other high value-added food etc.
The style change of DJL liquid nitrogen cabinet iqf freezer for 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. How fast is DJL liquid nitrogen freezing technology?
DJL Reply: There will be differences according to the different thickness and the packaging and different freezing temperature of product, when extreme temperature is used, DJL liquid nitrogen fast freezing speed can freeze naked frozen food with a thickness of 5CM in 3 minutes at the fastest., However, it is more common to freeze naked-food which up to 10CM thick within 10-30 minutes, usually used temperature between -80℃ to -120℃, extreme use of liquid nitrogen immersion, the temperature can reach -196℃.
2. 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.
3. What are the advantages of liquid nitrogen quick freezing compared with the traditional freezers and iqf freezer?
DJL Reply: Before answering this question, it is necessary for us to clarify the standard definition of quick freezing: quick freezing of food is to place the pre-processed food into a low-temperature device, pass through the largest ice crystal formation zone within 30 minutes, and the central temperature drops from 0℃ to Below -5℃, the diameter of the ice crystals formed is less than 100μm, and the center temperature of the food after quick freezing must reach the food freezing technology below -18℃. Due to its fast speed, the cell integrity of liquid nitrogen quick-frozen food was much higher than that of traditional freezing method, and the cell damage rate was nearly 80% less than that of slow-freezing food, so its taste, nutrition and color are much better than slow freezing food, In terms of seafood, DJL liquid nitrogen quick-freezing technology can be comparable to seafood in fresh state after freezing and thawing. Therefore, liquid nitrogen quick-freezing technology can better maintain the color, aroma, flavor and taste of food, and its sales value will also be greatly improved.
4. 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.
5. 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.
6. How much is the refrigeration consumption cost of liquid nitrogen freezer?
DJL Reply: The consumption cost of liquid nitrogen freezer is mainly divided into two parts, one is the electric charge, the other is the consumption of liquid nitrogen.The electricity cost is negligible compared with the traditional iqf freezer.
The consumption cost of liquid nitrogen quick freezing is liquid nitrogen. The liquid nitrogen consumption of quick-frozen food is mainly related to several factors such as water content, effective thickness, initial temperature, whether with packaging, and cooling method;. According to theoretical calculation and many years of experience at home and abroad, the consumption of liquid nitrogen for 1 ton of quick-frozen products is generally between 0.5~2 tons, and the consumption of liquid nitrogen for most naked frozen products is about 1.5 tons per ton. Some companies will deliberately say low consumption in order to get customers to buy equipment, but what we want is for customers to have real information to make rational decisions, rather than to be misled into a wrong cost model. We believe that the key for customers to choose liquid nitrogen quick-freezing technology is to greatly improve the quality of customers' products and bring premium and competitiveness, and the small increase in customer costs can be absorbed by the previous two items.
The price of liquid nitrogen will vary due to consumption and region, but if the quantity is large, the average price per ton will be RMB600-800 per ton, and the price will be lower in a few regions. DJL company can help customers find the lowest price of liquid nitrogen suppliers.
