Description

Technical Field

[0001] The utility model relates to the technical field of freeze-dried fruit processing, and more particularly to a device for mixing and crushing multiple freeze-dried fruits. Background Art

[0002] Freeze-dried fruit is a dried fruit product made by freezing fresh fruit and then removing its moisture under vacuum conditions. This process, called freeze drying, preserves the fruit's original color, shape, and nutritional content while removing most of the moisture, making it difficult for microorganisms to survive and extending its shelf life. This process is used in the production and processing of Ningling pears, apples, bananas, and other fruits.

[0003] Existing freeze-dried fruits will be crushed and mixed to make powder for use in water, etc.

[0004] The existing mixed pulverizing device for multiple freeze-dried fruits mainly pulverizes the frozen-dried fruits such as Ningling pears, apples, and bananas once through the pulverizing roller, which has a poor pulverizing effect, resulting in the frozen-dried fruits such as Ningling pears, apples, and bananas having a heavy grainy feel after pulverization.

[0005] Moreover, when mixing after crushing, mixing is mostly carried out through a stirring structure. During the mixing process, the crushed freeze-dried fruit powders such as Ningling pears, apples, and bananas need to be accumulated in a mixing box and then discharged after being fully mixed. In addition, the feeding needs to be stopped during the mixing process, and a streamlined operation cannot be achieved, which affects the processing efficiency. Utility Model Content
