在制剂生产过程中，特别是冲剂生产，有一道不可缺少的工序——筛分工序。该工序传统的操作方式一般为升式操作．这种操作方式是在与空气接触的暴露环境中，靠人工一次一次将物料填人振动筛内燃后从振动筛出口流入容器内。这种操作方法劳动强度大，粉尘飞扬．现对筛分工序的设? In the production process of the formulation, especially the production of granules, there is an indispensable process - the screening process. The traditional operation of this process is generally a lift operation. This operation method is that in an exposed environment in contact with air, the material is filled into the vibrating screen once by hand and then discharged from the vibrating screen outlet into the container. This method of operation is labor-intensive and dust is flying. What is the current screening process?
