This study was carried out to develop and investigate integrated mechanization system on polyethylene(P.E.) film mulching culture in sesame. Field trials were carried out to develop optimum mechanics for each step of manual operation in sesame culture and demonstrated those developed mechanics of sesame dibbling vinyl mulcher, sesame binder, sesame thresher and sesame grader at the farmer, s field of Hwasong (Kyunggi-do) in 1994 and 1995. Newly developed sesame dibbling vinyl mulcher brought saving manpower 280 hrs /ha for sowing and P.E. film mulching with it's 98% of labour saving for the harvesting operation of sesame. Sesame Binder showed 93% labour saving for cutting and binding with only 22 hrs /ha compared to 330 hrs /ha that of conventional. Sesame thresher was appeared to have 85% effects of labour saving for threshing with completely dry sesame bundles at one time by 23 hrs /ha compared to 151 hrs /ha that of conventional. Sesame grader was appeared to have 72% effects for sesame grain grading with 12 hrs /ha compared to that of conventional 54 hrs /ha. Grain yield of integrated mechanization culture system showed 6% higher than that of coventional. Integrated mechanization culture system (sesame dibbling vinyl mulcher + sesame binder + sesame thresher + sasame grader) showed 62% of labour saving effects through whole steps of sesame culture by 472 hrs /ha compared to that of conventional 1, 230 hrs /ha.

Separation Characteristic of Shatter Resistant Sesame After Threshing
( Hyun Kwon Noh ) 한국농업기계학회 2014 바이오시스템공학 Vol.39 No.4
Purpose: This study set out to develop a machine for separating shatter-resistant sesame after threshing. Methods: Three grades of sieve and different blower speeds were tested for a separation system that had been designed specifically for shatter-resistant sesame. Performance tests were run to evaluate the sieve and blower systems in terms of the sesame separation and loss ratios. Results: Tests of the first separation stage using the sieve system revealed the optimum sieve perforation size to be 5 mm. Tests of the second separation stage using the blower system identified the optimum blower speed as being 220 rpm. The optimum separation and loss ratios, of 96.5% and 3.5%, respectively, were obtained at a blower speed of 220 rpm. Conclusions: These results will be useful for the design, construction, and operation of threshing harvesters. For shatter-resistant sesame, an optimum blower speed of 220 rpm was identified.

Development of Threshing Machine for Shatter-Resistant Sesame
이규승,노현권 한국농업기계학회 2015 바이오시스템공학 Vol.40 No.2
Purpose: A threshing machine for shatter-resistant sesame was designed and developed in this study. Methods: Two typesof sesame (shatter-resistant and conventional) were tested using the developed sesame threshing system. Three types ofserrated bars were designed and evaluated through performance tests, in terms of the ratio of unthreshed sesame. Results:In the case of conventional sesame, the ratio of unthreshed sesame did not show any difference with bar type or cylinderrotation speed. For shatter-resistant sesame, however, the ratio of unthreshed sesame decreased with increased cylinderrotating speed for all three types of bar. Conclusions: These results are useful for the construction and utilization of anefficient threshing harvester. The type-L bar showed the best result in the energy equation.
