When using a drum powdering machine to powder raw meat, when the raw meat is relatively wet, the raw meat and the powder are mixed in the drum, and the powder after being mixed by the drum is easy to agglomerate. Once the wet powder agglomerates are formed, more and more agglomerates will be formed during the powder circulation process. If such powder is recycled, it will cause the machine to be blocked and operate smoothly, and it is necessary to stop the machine for treatment, which affects the work efficiency and the coating effect, resulting in poor powdering effect of the raw meat, unqualified final product quality, high defective rate, and entering the subsequent process flow, manual screening is required, which not only increases the labor cost but also reduces the production capacity. Therefore, the agglomerates generated during the production process by the conventional powdering machine will finally be all discarded, which causes waste of powder and increases the production cost.
