Liquid nitrogen quick-freezing machine has a wide range of applications in food processing, mainly reflected in the following aspects:
1. Seafood and aquatic products
Application: Liquid nitrogen quick-freezing machine is widely used in the freezing of fish, shrimp, shellfish and other seafood.
Advantages:
Quick freezing: Liquid nitrogen quick freezing can reduce the temperature of seafood to below -50 in a few minutes, effectively protect the cellular structure, reduce water loss, and maintain the freshness and taste of seafood.
High efficiency: the liquid nitrogen quick-freezing machine can work continuously without defrosting and improve production efficiency.
Reduce dry consumption: Compared with traditional freezing methods, the dry consumption rate of liquid nitrogen freezing machine is lower, usually only 0.25-0.5%.
2. Meat and poultry
Application: Liquid nitrogen freezing machine is suitable for freezing all kinds of meat (such as beef, pork, lamb) and poultry (such as chicken, duck).
Advantages:
Maintain meat quality: Rapid freezing to form tiny ice crystals, reduce damage to muscle cells, maintain meat taste and nutrients.
Extend the shelf life: liquid nitrogen quick freezing can effectively inhibit the growth of microorganisms and extend the shelf life of meat.
Improve safety: Rapid freezing can kill some bacteria and improve food safety.
3. Fruits and vegetables
Application: Liquid nitrogen freezers are used for freezing various fruits (such as strawberries, blueberries, mangoes) and vegetables (such as broccoli, carrots, spinach).
Advantages:
Preserve color and taste: Quick freezing can effectively retain the color, taste and nutrients of fruits and vegetables.
Reduce water loss: Liquid nitrogen quick freezing can reduce water evaporation and maintain the integrity of the product.
Extend shelf life: Liquid nitrogen quick freezing can effectively extend the shelf life of fruits and vegetables and reduce loss.
4. Pasta and baked goods
Application: Liquid nitrogen freezing machine is used for the freezing of bread, steamed bread, dumplings, steamed buns and other pasta and baked goods.
Advantages:
Maintain shape: Rapid freezing can maintain the shape and structure of the pasta to avoid deformation.
Reduce water migration: Liquid nitrogen quick freezing can reduce the migration of water in pasta and maintain the taste and texture of the product.
Improve production efficiency: liquid nitrogen quick-freezing machine can work continuously to improve production efficiency.
