Description

Technical Field

[0001] The invention relates to the technical field of pet food processing, in particular to a feed mixing device for producing pet food. Background Art

[0002] Pet food processing needs to go through a series of processes to produce food suitable for pets. Different pets have different requirements for nutrients, and the formula needs to consider the proportions of ingredients such as protein, fat, vitamins and minerals. Common raw materials include meat, grains, vegetables and additives. Pet food usually contains two or more feeds, and it is usually necessary to mix multiple feeds during processing to ensure that pets have a more balanced nutrition when using it.

[0003] Some existing pet food processing mixing devices, when actually used, usually pour the required feed into the mixing device according to the proportion, and then mix and stir the feed. However, since a large amount of feed is easily piled up together, the mixing is not uniform during stirring, resulting in low mixing efficiency, which will reduce the use effect of the mixing device. In addition, when a large amount of pet feed is stirred at the same time, it is easy to cause more debris to be generated in the originally granular feed, thereby reducing the quality of the feed and thus reducing the use effect of the mixing device. Therefore, the above problems need to be solved. Summary of the invention
