Application scenarios of single spiral quick freezing machine
The single spiral quick freezing machine is widely used in various fields of the food processing industry due to its compact structure, small footprint, and strong freezing ability. This device is particularly suitable for the quick freezing needs of meat, processed foods, seafood, dishes, and ice cream. Its design is flexible, and the inlet and outlet can be "low in, high out" or "high in, low out" to adapt to different production layouts. The production range is 500 to 1500 kilograms per hour, which can meet the needs of various scales from small and medium-sized enterprises to large processing plants.
In meat processing, the single spiral quick freezing machine maintains the freshness and tenderness of meat through rapid freezing; For aquatic products, it can effectively lock in the natural flavor of seafood. In addition, on the production line of frozen foods such as dumplings and baked goods, it ensures that the taste and nutritional content of the food are not lost throughout the entire freezing process. Not only that, the catering industry also utilizes this equipment to achieve rapid freezing of food, which is both convenient and ensures consistency in the dining experience.
The importance of quick freezing
With the continuous improvement of consumers' requirements for food safety and quality, efficient and high-quality quick freezing technology has become particularly important. Freezing not only extends the shelf life of food, but also maximizes the preservation of its original texture, color, and nutritional value. For example, when processing products like puff pastry, the use of a spiral freezer significantly improves product quality while reducing energy consumption and labor costs. This is because the small and uniform ice crystals formed during the quick freezing process do not damage the cell structure, allowing the thawed food to still have a good appearance and taste.
Working principle
The single spiral freezer adopts a spiral conveyor system to complete the entire freezing process. The material is placed on the conveyor chain after entering through the feeding port and moves along the spiral path. During this period, powerful cold air flows through the material layer to deeply freeze it. Under normal circumstances, the internal operating temperature of such devices can reach between -35 ℃ and -40 ℃, while the wind speed is maintained at around 4-6 meters per second to ensure that each item can quickly drop to the required core temperature (generally below -18 ℃). In order to further improve efficiency and save energy, some models are also equipped with windshield devices to prevent unnecessary losses caused by direct leakage of cold air.
