Product description
Refrigeration principle of liquid nitrogen quick freezer
The principle of quick freezing of liquid nitrogen food: quick freezing of food generally refers to the use of modern freezing technology, using liquid nitrogen as the refrigerant to reduce the temperature of the food to the expected low temperature below its freezing point. All or most of the moisture contained in the food will form reasonable tiny ice crystals along with the heat dissipation inside the food. At the same time, the liquid nitrogen quick-freezer freezes part of the free water of the cells and reduces the water activity without the help of any preservatives and additives. At the same time, the food nutrition is preserved to the greatest extent. It has the advantages of delicious, convenient, healthy, hygienic, nutritious and affordable original food.
The advantages of liquid nitrogen quick freezer frozen food
1. Liquid nitrogen is non-toxic and inert to food ingredients. Moreover, because it replaces the air coming out of the food, it can reduce the oxidation changes to the minimum during freezing and cold storage with packaging.
2. Liquid nitrogen can be in close contact with all parts of food with irregular shapes, which reduces the thermal resistance to the smallest limit.
3. The frozen food is of high quality. Since liquid nitrogen is in direct contact with food, the heat exchange is carried out with a temperature difference of more than 200K, so the freezing speed is extremely fast, and the temperature can be reduced by 7-15K per minute. The ice crystals in the food are small and uniform, and the quality of the food after thawing is high.

FAQ:
1. 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.
2. How long can the liquid nitrogen freezer be used?
DJL reply: 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.
3. 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.
