Structure design and performance test of the 5PZX-600 hops separating machine

The 5PZX-600 hops separating machine as a new prototype machine that has higher separating effectiveness, lower impurity ratio,and wider adaptability to separating of the whole hop cultivars including the' Qingdao Macroflora' was developed. The structure design plan, working principle,main parameters and the test results of its prototype machine were introduced in this paper. Through kinematic property analysis of hop leaves, the conditions for separating flowers from leaves were sought out. According to the test results and regression analysis,the mathematical model on every property indexes of the machine was established,and thereby the optimum parameter combination was acquired as follows:feeding quantity was 150. 8 kg,rotational speed was 288 r/min,and the natural fragmentation ratio was 1. 9 %,the cleanliness ratio was 99. 1 %, the ratio of carrying secretly loss was 3. 18 %, and the ratio of splash loss was 0.32 %.
