Brykhovetsky A. Increasing efficiency of technological process of secondary potato separation

The thesis is devoted to the problems of increasing efficiency as to the technological process of potato hear secondary separation. As a result of analysis of the existing methods, de-vices and working parts for secondary potato separation the necessity of an airfriction separa-tion for potato heap. On the basis of the theory of probability of dry substances and using system analysis methods a constructive and technological scheme of an airfriction separator has been devel-oped. A theoretical analysis of potato heap separation process has been carried out. Mathemati-cal models of potato tubers movement along the working surfaces of the separator have been constructed. As a result of this research an airfriction two-stage potato separator has been designed, and by optimization of each stage operation has proved its great capacity for work and effi-ciency. Recommendations on the use of the given technical device have been worked out.
