one、 Characteristics of tunnel type liquid nitrogen quick freezing machine:
1. Fast freezing speed: Compared with traditional air forced circulation freezing devices, the heat transfer intensity has increased by about 30-40 times. This is because the thermal resistance during freezing decreases by about 15-18 times, the heat release coefficient between the product surface and cold air increases by about 4-6 times, and the effective heat transfer area increases by about 3.5-10 times. So the freezing speed is dozens of times higher than that of ordinary freezing equipment. Due to the fast freezing speed, it can greatly maintain the original nutritional composition and freshness of the food.
2. Realize rapid freezing of individual units: Food will not stick together after freezing, achieving IQF freezing, which not only has good quality but also is convenient for packaging and consumer consumption.
3. Low dry consumption of food: Each frozen food has a thin ice film on its surface, which not only helps to maintain food freshness and prevent oxidation, but also reduces dry consumption. The comparative experiments conducted by Swedish scholars on mushrooms, strawberries, etc. show that the dry consumption of liquid nitrogen freezing is almost half of that of forced ventilation tunnel freezing. This is particularly important for higher priced foods.
4. Easy to achieve mechanized and automated continuous production, high production efficiency: workers operate at room temperature, improving labor conditions.
two、 Introduction to Tunnel Type Liquid Nitrogen Quick Freezer Technology
1. The box is made of food grade 304 stainless steel material, which has undergone precision CNC processing and can be made into various lengths and specifications to meet the different requirements of the majority of users. The equipment thermal insulation features: good thermal insulation performance, light weight, high strength, corrosion resistance, aging resistance, and beautiful appearance.
2. Adopting liquid nitrogen refrigeration method, introducing German fast freezing technology, combined with numerous domestic aquatic product research, equipped with German imported fast freezing technology, and controlled by imported PLC and touch screen. The equipment operates stably, is efficient, energy-saving, and environmentally friendly. Capable of meeting 24-hour continuous production needs.
