碾压式油茶籽脱壳装置设计及仿真分析
|
摘要
参考已有物料脱壳方法,结合油茶籽生物学特性,设计出一套轻巧型碾压式油茶籽脱壳装置,并构建了基于ADAMS的油茶籽脱壳装置仿真模型。结果表明:螺旋板具有很好疏导油茶籽的作用,能够使油茶籽在轴向均匀分布,防止拥堵;油茶籽在辊轴压筋的驱动下,随辊轴在筛网内转动,破壳后从出料口下落;油茶籽破壳力约为88.1 N。样机试验表明:脱壳装置设计方案可行,运行稳定,油茶籽脱壳率高达95.62%,碎仁率降低为1.35%。
Based on the existing method of shelling,and combining with the physical characteristics of camellia seed,a rolling type camellia seed sheller with simple construction and small size was designed in this paper. And then the simulation model of sheller was set up by ADAMS software. Simulation results show that the spiral lamina has a very good effect on dispersing camellia seeds,which can make camellia seeds uniformly distributing along the roll shaft,so as to put an end to feed-throat clogging. Camellia seeds firstly move with roll shaft in the screen mesh,then drop from outlet after the seed shell have been broken. The shelled force of camellia seed is about 88.1 N. The prototype test shows that the design is feasible and valid,and the hulling rate can reach to 95.62%,the kernel-unbroken rate decrease to 1.35%.
