[0002] As one of the sources of daily food for pets, pet food is mainly divided into puffed food and baked food. Baked food can be further divided into puffed type and freeze-dried type. Freeze-dried pet food is widely promoted and used due to its portability and dryness. In the freeze-drying process of pet food, the pet food to be processed is usually placed in a freeze dryer. The internal refrigeration system, vacuum system, thermal oil heating system and other components are used to freeze the pet food, and the water contained in some molecules is discharged to the surface of the material to freeze, meeting the freezing requirements. Then the heating system heats and dries the material, and takes out the water contained in the pet food, meeting the freeze-drying requirements of the material.

[0003] However, in the existing freeze-drying process of pet food, since freezing and heating are performed in the same device, the energy loss is large during the cold and heat exchange process, the freeze-drying cost is high, and each time the pet food is freeze-dried, the device needs to be opened to take out the pet food, and then the device needs to be restarted before the next group of freeze-drying can be performed, which further increases the loss of capacity. To this end, those skilled in the art provide a freeze-drying device for pet food processing to solve the problems raised in the above background technology. Utility Model Content
