Optimization of machine parameters of Parvatiya Sugam motorized thresher using response surface methodology

Abstract

A Parvatiya Sugam Thresher was designed and developed at College of Home Science GBPUA & T, Pantnagar, Uttarakhand, India. It is a low cost motorized machine for threshing paddy crops especially for hill region, it is user friendly and more efficient in its working. The machine performance was evaluated for optimal design parameters viz, height 755 mm, time 5.1 minutes and crop load 1.5 kg. Comparative performance tests between the newly developed (Parvatiya sugam thresher) and existing thresher were conducted to the optimization. Test result indicates that Parvatiya sugam thresher gives better result compared to existing thresher. It was inferred that ½ hp motor was introduced to have optimum drum speed and threshing performance of paddy thresher.

Perspective Analysis of the Physical and Engineering Properties of Coriander Seed at Different Moisture Contents

“…Similar trends were found for coriander seeds by Coskuner and Karababa, [16] and for lentil seed by Bagherpour et al, [20]. Hence, the inclination of seed outlet was kept at 35 0 for better flow [21][22][23][24][25][26].…”

Optimizing operational parameters of finger millet threshing drum using RSM

“…Myers et al (2009) reported that the RSM helps to reduce the number of expensive experimental analysis and involved associated noise in it. Similar technique was used by many researchers viz., Singh et al (2008) for optimizing machine parameters of paddy thresher, Salari et al (2013) for optimization of operational parameters of chickpea thresher, Singh and Deepa (2014) for optimizing machine parameters of parvatiya Sugam motorized thresher, Tewari et al (2013) for performances modeling of ground nut stripper and Pishgar-Komleh et al (2012) for optimizing seed corn harvesting losses. To achieve maximum threshing efficiency, pearling efficiency and minimum grain damage there is need to maintain optimum operating parameters of the threshing drum.…”
