多収品種「あきだわら」を飼料用米として利用した際の籾米水分および脱芒処理がインペラ式籾摺り機における生籾米の脱ぷ性能に及ぼす影響

In this study, the applicable range of fresh paddy water content suitable for feed rice in a brown rice drying system, factors that lower the efficiency of husking, and the effects of water content reduction and the awning process on husking were examined. The results indicated that the fresh paddy water content range of 16.8-30.8%, loss of total digestible nutrients due to differences in husking ratio and embryo deficiency rate was small. Furthermore, a significant decrease in yielding percentage with increasing broken kernel rate was not observed. Therefore, direct husking of fresh paddy with an impeller type husker was possible. The relationship between the angle of repose and husking performance suggested that the main factor reducing husking performance was the decrease of flowability in fresh paddy. Reduction of water content and the awning process effectively improved husking performance because they improved flowability in fresh paddy.
