1.8t全自动油茶青果脱壳机设计与试验

Aiming at the problems of low processing capacity,low de-purification rate and high breakage rate in the in the process of shelling fruits of Camellia oleifera,a four-channel Camellia oleifera fruit shelling machine was designed.The camellia oleifera fruit within the size range enters the corresponding shelling drum,and the Camellia oleifera fruit is shelled by colliding with the shelling sleeve and drum wall,the shelling of Camellia oleifera fruit is realized by collision,extrusion and rubbing.In order to verify whether themachine achieves the expected shelling effect,taking the shelling rate of Camellia oleifera fruit and the breakage rate of Camellia oleifera fruit as the evaluation indicators,and taking the torsion angle of the shelling disc,the feeding amount,and the diameter of the shelling rod as experimental factors,the orthogonal rotation combination was carried out.The test results show that when the torsion angle of the shelling disc is 24.84°,the feed rate is 1845.47kg/h,and the diameter of the shelling rod is 25.02mm,the shelling effect is the best.Three parameter combination tests were carried out on the torsion angle of the shelling disc is 25°,the feed rate is 1845kg/h and the diameter of the shelling rod is 25mm.The test results were taken as the average values of the three tests.After calculation,the net removal rate was 98.32%and the damage rate of tea seeds was 2.33%.
