Haomai automatic pineapple freezing machine lychee quick-freezing equipment fruit lock quick-freezing equipment Q02 liquid nitrogen quick-freezing machine working principle and advantages The working principle of liquid nitrogen quick-freezing machine is — “non-direct contact freezing of frozen items with low-temperature liquid (liquid nitrogen)”; put packaged fresh food (fish, meat, etc.) into the freezer, and quickly reduce the temperature in the liquid nitrogen quick-freezing machine to below -120℃ (The temperature can vary depending on the food Set), and then freeze it within 2 to 15 minutes to avoid the ice crystal formation period inside the food, keep it intact, and do not lose nutrients after thawing, and maintain the original flavor, taste, and nutritional value of the food, which is even better than fresh food in terms of taste. Liquid nitrogen quick-freezing machine has the following advantages: 1, quick freezing time, large output per unit time, high efficiency, suitable for continuous food processing, 2, long fresh-keeping time, good food quality, less dry consumption, and can keep the freshness of food well; 3, the same output is low energy consumption, small cooling loss, low operating cost; 4, less investment, saving more than 30% compared to traditional cold storage quick-freezing; 5, at the temperature Frozen, bacteria are generally covered Kill or stop breeding Suitable for: 1. Seafood: raw/cooked/shelled /shelled shrimp products, soft seafood, oyster products, scallop products, all kinds of fish fillets, sushi products; 2. Poultry and livestock: raw or cooked diced, flake or strip products; 3. Fruits: strawberry, pineapple, papaya, mango, longan, lychee - diced, diced or diced Whole fruits 4. Vegetables: diced or sliced mushrooms, sweet Corn kernels, fresh beans, pods, herbs (such as frozen celery); 5. Dairy/noodles: pastries, individually packaged pasta, tofu cubes. Efficiently and economically freeze products placed inside quick-freezers. The original nutritional value and color and aroma of food are maintained to the greatest extent possible.
