Development of a Full-View-Type Grading Cup for Automated Sweet Cherry Sorters

In order to improve the adaptability of sweet cherry sorters cherries, a full-view-type grading cup for automated was developed based on physical characteristics three species cherries: Tieton, Huang Mi, and Lapins. The structure working principle are described in this paper. main factors affecting operating stability were identified study by analyzing mechanical properties cherries during conveying rotating process. According Box-Behnken test design method, we took speed, Young’s modulus, friction coefficient double-roller supporter as success rate index. parameters tested studied, regression model between index established. influence law each factor analyzed, comprehensively optimized according model. results showed that when speed 48 cherries/min; butadiene rubber (BR) 9000, with modulus 0.012 GPa selected material making double-support rollers; designed be 15, 86.0%. research have provided theoretical basis optimization cups sorters.
