Liquid nitrogen quick freezer
                                                                Liquid nitrogen quick freezer
a、 Main technical indicators of liquid nitrogen quick freezer (double door):
1. Refrigerant: liquid nitrogen;
2. Working temperature range: room temperature -190 ℃;
3. Spray cooling method: multi-point atomization spray;
4. Cooling rate: ≤ 30 ℃/min (empty box operation);
5. Temperature control method: intelligent control;
6. Power distribution specifications: AC380V/50Hz (220V can also be selected);
7. Power consumption of the whole machine: ≤ 1.5KW;
b、 Function and characteristics of liquid nitrogen quick freezer:
1. Material support: Mobile adjustable 304 stainless steel material support;
2. Refrigeration system: Liquid nitrogen vaporization evaporation refrigeration system, pneumatic solenoid valve temperature drop, frequency conversion speed regulation dual fan cycle refrigeration;
3. Equipment insulation: the insulation layer is polyurethane foam insulation, with a thickness of 150 mm, good insulation performance and safety;
4. Equipment system: a liquid nitrogen circulation atomization spray system using German imported technology;
5. Air cooling cycle: high-power fan equipped with reinforced axial flow fan, adjustable wind speed, fast and uniform cooling speed;
6. Equipment control: touch screen+PLC automatic program control system, simple and easy to learn input, intuitive and reliable control, with temperature monitoring and alarm functions, ensuring the safe operation of equipment and processes;
7. Equipment maintenance: easy to clean, easy to maintain, designed with long service life and low consumables;
8. Due to the fast freezing process, food that has been frozen by this machine can maintain its color, aroma, taste, and nutritional value to a large extent before processing. Reduce moisture loss, low loss, without reducing weight. The time for the formation of ice crystals is about 3-9 minutes, while regular freezing takes about 90 minutes or more. Due to the ability of rapid freezing to freeze the colloidal bound water, free water, and free water in the intercellular space into countless fine and uniform ice crystals, the cell tissue is not damaged. Therefore, after thawing, the food can be restored to its original fresh state and nutritional content to a greater extent.
The dry consumption of frozen food is low. Food frozen with conventional freezing devices has a dry consumption rate of about 3% to 6%, while frozen with liquid nitrogen freezing devices can reduce it to about 0.25~0.5%, which is particularly important for higher priced foods.
