In the process of feed production, when the finished material falls into the finished product warehouse, due to the different particle size and specific gravity of the feed, the finished feed is classified under the action of gravity and vacuum, and the packaged finished product is different, which affects the quality of the finished product. In order to solve the problem of feed grading caused by the feed production process. After repeated experiments, the company has designed and developed "feed product warehouse with anti-grading buffer structure" and related patented technologies to achieve high-quality large-scale production. The application of this technology can achieve ideal uniformity, and the variation coefficient of the finished material entering the finished product warehouse from the mixer is not higher than 3%, reducing the waste of raw materials, energy and manpower.
Develop a finished feed silo with an anti-grading buffer structure. There is a vertical guide pipe in the silo, a fixed bracket is arranged between the guide pipe and the silo wall, and at least one layer of buffer wings is arranged on the wall of the guide pipe every meter. The number of each layer of buffer wings is at least three, the guide pipe is provided with overflow ports corresponding to each buffer wing, and the side wall of the bin and each layer of buffer wings are provided with return air pipes. It effectively solves the problem of grading of finished feed products due to the effect of self-flow and vacuum phenomenon due to the different crushing particle size and specific gravity of the feed when it enters the finished product warehouse after being processed and mixed, and achieves the ideal uniformity. The posterior coefficient of variation was not higher than 3%.
