Substantiation of rational parameters of the root crops separator with a rotating inner separation surface
The aim of the paper is to justify the design and rational parameters of the secondary post-treatment separator of potato heap in the form of a truncated cone with a rotating internal separating surface which ensures the separation of potato tubers from soil lumps commensurate with them. Based on the analysis of works devoted to the process of potato heap separation, including on inclined surfaces, as well as the analytical calculations, it was concluded that it is possible to create a device for separating potato tubers from soil lumps in the form of a rotating truncated cone with an internal separating surface. As a result of the research, the design of the secondary post-treatment separator of potato heap in the form of a rotating drum in the form of a truncated cone with a separating roller. Laboratory and field tests have shown that with appropriate adjustments, separation of up to 80% of soil impurities commensurate in size with potato tubers is provided.
