[0002] A quick-freezing machine is a high-efficiency freezing device that can rapidly reduce the center temperature of food to-18 DEG C or lower in a very short time. Such a rapid freezing process is crucial for maintaining the nutrition, color, aroma and freshness of food, because it can reduce the size of ice crystals inside the food, thereby reducing cell damage and preventing food spoilage and deterioration. The quick-freezing machine is widely used in the food industry, can extend the shelf life of food, improve its market value, and facilitate transportation and sales.

[0003] The quick-freezing machine generally uses a mesh belt to convey and freeze products. During the conveying process of the products, the tension, speed and position of the mesh belt will all affect the normal operation of the quick-freezing machine. If the tension is too large or too small, it may cause the mesh belt to break or slip, affecting the quick-freezing effect. Uneven speed will cause uneven freezing of food. Position deviation may cause food to fall off, causing production accidents. In addition, the quick-freezing temperature will also directly affect the quick-freezing effect.
