Optimizing the frequency of oscillating beater in double roller gin

Abstract

Variable speed double roller gin has been used to optimize the frequency of oscillating beater, considering three levels of oscillating frequency, namely 750, 1000 and 1250 cpm and conventional frequency of 1000 cpm. The factors considered for optimum rates include lint turn out, fibre quality and ginning rate. Overall, the fibre quality remains unaffected for all types of cottons, whereas the lint out-turn and ginning rate are found to be highest at 1250cpm frequency for long and extra long staple cottons. The conventional frequency is found to be better for short staple cottons. The short fibre content, seed coat neps and neps in the lint are comparatively less at higher frequency.
