Substantiation of the Design and Layout Scheme for the Gravity-Pneumatic Soybean Seed Cleaner

It is shown that scientifi c research into the intensifi cation of soybean seed separation processes necessary for developing new type purifi technologies eliminate shortcomings traditional machines, as well achieving more favorable technical and economic indicators grain cleaning equipment. ( Research purpose ) To substantiate design parameters a sorting plant highly efficient seeds. Materials methods We used developed prototype model seeds, consisting gravity column pneumatic channel. The number combs in gap between comb bars were substantiated. Subject to different supply material, completeness separating large impurity was determined column, light – first section channel, halves second small puny seeds third one. Results discussion optimal set 10 pieces with millimeters, thus providing effi ciency 99.3 percent. obtained ratio width narrowing partition 50-millimeters depth channel equals 0.37. partitions calculated be 55.5 millimeters; soybeans 2.5 tons per hour, no less than 95 percent, 98 Conclusions process possible by combined use device, which can increase productivity 20 percent or more.
