Quick Freezing Machine Tunnel Blast Freezer for Fruits Cherry Chicke Vegetables Seafood Shrimp Fish
Freezing is an essential aspect of food preservation that helps prolong the life of perishables. The conventional freezing methods were quite slow and inefficient, but with the advent of technology, better freezing techniques have been developed. Among the new technologies is the tunnel freezer, which is a fast and efficient method of freezing food products. Tunnel freezer has revolutionized the food industry as it allows food manufacturers to process large amounts of food products efficiently.
Mesh Belt Tunnel Freezer
The mesh belt tunnel freezer has a conveyor belt that moves products through the freezing chamber. It is suitable for food items that are small and can pass through the mesh belt. The belt is usually made of stainless steel wires mesh that is tightly woven to prevent the product from falling off during the freezing process.
The mesh belt tunnel freezer uses a cryogenic gas, such as nitrogen, to freeze the food products. Liquid nitrogen is sprayed into the freezer chamber, which lowers the temperature to the required level. The cryogenic gas is a fast and efficient method of cooling as it has a lower temperature than other refrigerants, and it also has a high heat transfer coefficient. The gas can easily penetrate the food items, making it possible to freeze even the most delicate food products.
The mesh belt tunnel freezer is the preferred choice for freezing small food products like vegetables, fruits, and seafood. The freezer energy consumption is low, and the freezer is easy to clean, making it the ideal choice for food manufacturers.
Plate-Belt Tunnel Freezer
The plate-belt tunnel freezer is a more advanced version of the mesh belt tunnel freezer. Unlike the mesh belt tunnel freezer, the plate-belt tunnel freezer uses plates instead of a mesh belt to convey the food products through the freezer chamber. The plates are made from a food-grade aluminum alloy that offers excellent thermal conductivity.
The plates chill the food products by contacting it directly, ensuring uniformity in temperature and quality. The plates' design is unique, with each plate having a thickness of 40mm to add to the freezer's insulation efficiency. The plates act as both the conveyor and the heat exchanger that removes the heat from the product, making it possible to freeze even the most delicate foods.
The plate-belt tunnel freezer is suitable for a wide range of food products, including meat, poultry, bread, and dough. It is popular due to its high output, energy efficiency, and superior quality of the frozen products.
In conclusion, the tunnel freezer has revolutionized the food industry by offering a fast and efficient method of freezing food products. The two types of tunnel freezers, namely the mesh belt tunnel freezer and the plate-belt tunnel freezer, offer distinct advantages to food manufacturers. The mesh belt tunnel freezer is suitable for small food products, such as fruits and vegetables, while the plate-belt tunnel freezer is ideal for a wide range of food products, including meat, poultry, bread, and dough. As technology continues to evolve, better freezing methods will continue to emerge, providing food manufacturers with more options to improve their products' quality and shelf life.
