Abstract

Objectives: The Objectives of present research work is to investigate the effect of the mechanisms involved in the rice milling process. So that what is the technological improvement can be made. Methods/Statistical Analysis: To identify the rise in temperature and wear patterns present on major machine components of rice polishers. Use of rice milling mechanisms to analyses: temperature, wear, and mechanisms. The testing to identify, the behaviour of the current milling machine materials and their wear resistance in order to set a benchmark from which to measure alternative materials. Findings: Using the understanding of the Rice milling processes to determine what improvements can be made to machine design to reduce the rice in temperature percentage of the wear components. Application/Improvements: It is known that changes in temperature beyond 500C cause change in material properties increasing in the susceptibility of rice grains to cracking and fissuring. Hence in our design of the polishing system, the rise of grain temperature is kept below 200 C to ensure good polishing performance.
