Design, Fabrication and Evaluation of Sesame Continuous Huller

Dehaulling is one of the important stages in sesame grain processing. It includes soaking، dehusking the grain، and separating the husks from kernels. In the present study، a continuous dehuller for an industrial continuous process layout of grain was designed، fabricated and evaluated. The slope and speed of dehuller were the main factors for laboratory experiments. Results depicted both factors have significant effect on dehulling efficiency (p=0. 01). Maximum efficiency was measured about 84 percent at zero slope and minimum speed of dehuller in a single pass trial. A strong linear relationship between dehulling duration time and efficiency with correlation coefficient of 0. 80 was observed. This machine has capability of extra efficiency with increasing in dehulling duration through other adjustments.
