Description

TECHNICAL FIELD

[0002] In a modern feed production process, the use of additives has become one of the key technologies for improving feed quality, enhancing animal health and promoting production efficiency. Feed additives usually include vitamins, minerals, amino acids, enzyme preparations and various nutritional ingredients. These additives need to be uniformly mixed into the feed base to ensure that each particle can be fully supplied with nutrients.

[0003] The existing mixing device generally adopts a design with only one stirring shaft. Although this structure can complete the basic stirring task to a certain extent, due to the single stirring operation and limited mixing area, the mixing of the additives and the feed base in the stirring process often cannot achieve uniform results. Especially in the case of fine or highly viscous additives, the traditional single-shaft stirring device is difficult to fully disperse and uniformly distribute the additives, resulting in higher additive concentration in some areas and insufficient additives in other areas. This not only affects the nutritional balance of the feed, but also may affect the health and growth of animals.

[0004] Therefore, the application provides a feed additive proportioning and mixing device to solve the above problems. CONTENT OF THE UTILITY MODEL
