Stripping Process for Removing Grains; History and Consequence

The process of stripping for removing rice grain was attained before the modern era in Japan and led to the development of the head-feeding type thresher. The head-feeding type thresher incorporates 'the potential of the stripping principle' - high performance of removing rice grain with low requirement of energy. On the other hand, the stripping action has been generally recognised as the reaping of standing crops. This paper reviews the history of the action and process of stripping with a view of defining the fundamental consequences for further development of existing discussions on removing grains.
