切割式油茶果脱蒲机设计与试验

为提高油茶果机械化脱蒲效果和便于进行茶籽与茶蒲分离,在油茶果物料特性研究的基础上,设计了一种由切割结构、脱蒲结构等组成的切割式油茶果脱蒲机.选取辊筒转速、橡胶板转速及切割深度3个关键因素,以油茶果脱蒲率、有效得率和分离率为指标进行试验研究.结果表明:随着辊筒转速的增加,脱蒲率先增加后降低,最高为87％;分离率的变化较小...

Design and Experiment of Cutting Type Camellia oleifera Fruit Shelling Machine

In order to improve mechanical dehulling effect of Camellia oleifera fruit and facilitate separation of tea seeds and tea husks，a cutting type Camellia oleifera fruit peeling machine，which was composed of a cutting structure and a dehulling structure，was designed based on characteristics study of Camellia oleifera fruit material.Three key factors of roller speed，rubber plate speed and cutting depth were selected，and index of shelling rate，effective yield and separation rate of Camellia oleifera fruit was used for experimental research.Results showed that with increase of roller speed，shelling rate firstly increased and then decreased，the highest was 87%; separation rate changed little; effective yield firstly decreased and then changed within a certain range，the effective yield was the lowest at 98.8%.Speed of rubber sheet had the most obvious effect on effective yield，and effective yield gradually decreased with the increase of speed of rubber sheet，reaching a minimum of 94.2%;speed of rubber sheet had little effect on peeling rate and separation rate.As cutting depth increased，shelling rate and effective yield had increased significantly，with the highest shelling rate being 97% and the lowest effective yield being 95.2%;overall separation rate had not changed much.
