As a key component of feed, livestock and poultry functional premixes can provide comprehensive and balanced nutrition for livestock and poultry, and have specific functions, such as promoting growth, enhancing immunity, and improving meat quality. Therefore, the efficient and accurate preparation of livestock and poultry functional premixes has become an urgent need for the development of the industry.
[0003] There are many defects in the traditional equipment and methods for preparing functional premixes for livestock and poultry. It is difficult to achieve precise feeding control with traditional equipment. Continuous and uninterrupted feeding easily causes raw materials to pile up in the mixing barrel and uneven mixing. The lack of regular feeding speed will also affect the production rhythm and reduce production efficiency. In terms of collection, the collection box lacks effective material dispersion measures. The materials are often concentrated in the middle of the box, which not only reduces the space utilization of the box, but also causes excessive local pressure and shortens the service life of the box. In addition, the concentrated distribution of materials is not conducive to subsequent transportation and use, increasing production costs and operating difficulties.
