Mechanism and Experimental Research on Hops Separation With Vibrating Screen

Separating hops with vibrating screen can greatly downsize the separation part of hops picking machine and reduce the manufacturing cost of the hops picking machine. The basic principles of hops separation with vibrating screen was discussed and the kinematical property of material on the screen was analyzed in this paper. Experiments showed that the separation quality was mainly influenced by the angle of vibrating direction, the angle of inclination of the vibrating screen and the revolution speed of the crank. Based on the experiments a mathematical model was established. It can be used to simulate the separation quality and optimize the parameters to improve separation process.
