Description

Technical Field

[0001] The invention relates to the technical field of food quick-freezing machines, in particular to a mobile food quick-freezing machine and a quick-freezing process thereof. Background Art

[0002] A food quick freezer is a highly efficient freezing device that can freeze a large number of products in a short period of time. Its main purpose is to reduce the center temperature of the quick-frozen items to -18 degrees Celsius in a short period of time to reduce the loss of nutrients and maintain the original flavor of the food. There are many types of quick freezers, including push-type quick freezers, reciprocating quick freezers, flat quick freezers, fluidized state quick freezers, tunnel quick freezers, spiral quick freezers, lifting quick freezers, etc. They are commonly used equipment in the food production and processing process. Food production and processing uses high-pressure liquid nitrogen bottles to pressurize the liquid nitrogen tank so that the liquid nitrogen is sprayed onto the material on the conveyor belt through valves and nozzles. In this process, the low temperature of the liquid nitrogen quickly reduces the temperature of the food, thereby achieving the effect of quick freezing of food.

[0003] In the current prior art, food is quickly frozen using a food quick freezer, and the food to be quick-frozen is transported to the food quick freezer via a conveyor belt for rapid cooling and quick freezing. However, the low temperature environment of quick freezing will cause the conveyor belt to be in a low temperature state for a long time, and then the vibration in the mechanical transmission will cause the wear of the conveyor belt to increase, resulting in a shorter service life of the conveyor belt. In addition, food quick freezers are generally not convenient to move, which makes it inconvenient to transfer different production lines. Therefore, a mobile food quick freezer and a quick freezing process thereof are proposed to solve the above problems. Summary of the invention
