Guangdong Science and Technology Exchange Center, Guangdong Guangzhou, 171 Lianxin Rd. 510033, China acjwuyi@126.com, bruanjl@126.com, cwuweiweistec@126.com Keywords: rubber roll husker; working parameters; husker capacity; optimization Abstract: In rice processing courses, the working parameters of rubber roll husker, including contact pressure between rolls, inlet flow, fast roll linear speed and linear speed difference, will affect the husker capacity.
Therefore, under the premise of keeping high steady husking rate and decreasing raw broken rate, it is important to investigate the working parameters’ influences on the husker capacity in order to rise the production rate per machine, lower the processing cost, and ensure qualified technological performance. 1 Material and Method 1.1 Experimental Material and Equipment The raw material was mid-class early long-grain non-glutinous rice with 13% moisture rate.

It will consequentially result in more cutting heat, diminish the yield strength of the material, and eventually bring in larger plasticity distortion.

In 2002, Lorant et al developed the Smile-Agent system, described the overall model of workshop layout by three levels of the production, inventory and material handling[7].
In the workshop layout, there are different layout models and methods due to different target, the most common target is to minimize the logistics cost (material flow cost) of the whole workshop.
