项目摘要

THE TRIAL FOR APPLYING THE IMPELLER TYPE HUSKER TO THE DIRECT HUSKING OF THE HIGH MOISTURE CONTENT OF RICE STANDING IN THE PADDY FIELD WAS ATTEMPTED. IT WAS FOUND THE IMPELLER TYPE HUSKER COULD BE SUCCESSFULLY MOUNTED AND APPLIED FOR ACTUAL HUSKING OPERATION ESPECIALLY FOR HIGH MOISTURE CONTENT OF RICE. THIS FUNCTION HAS THE HIGH POSSIBILITY AND POTENTIALITY IN SHORTENING THE HARVESTING AND PROCESSING OPERATION IN POST-HARVESTING STAGE. FOR SATISFACTORY HUSKING, THE QUALITY OF BROWN RICE MUST BE CONSIDERED SERIOUSLY, HOWEVER SOME OF THEM CAN BE USED FOR FEEDING TO ANIMALS. THEREFORE, THE RICE TO BE USED FOR ANIMAL FOOD OR PROCEED PRODUCTS, THIS HUSKING SYSTEM CAN BE IMMEDIATELY APPLIED, BECAUSE THE QUALITY IS NOT CONSIDERED SO CAREFULLY. FOR THE RICE AS THE MAIN FOOD FOR HUMAN BEING, THE HIGH QUALITY IS REQUESTED IN ADDITION TO THE PRICE. IN HUSKING OF THE HIGH MOISTURE CONTENT OF RICE, THE PERIPHERAL SPEED OF THE IMPELLER SHOULD BE NECESSARILY INCREASED FOR BETTER HUSKING MAINTAINING … More THE HIGH PERCENTAGE OF HUSKING, HOWEVER NATURALLY THE INJURY AND DAMAGE ONTO THE GRAIN(BROWN RICE) IS INCREASED BECAUSE OF THE INCREASE OF IMPACT FORCE ACTING ON THE GRAIN IN THE PROCESS OF HUSKING.IN THIS RESEARCH PROJECT TWO TYPES OF HUSKING METHOD WERE COMPARED AND THE CHARACTERISTICS OF THE DAMAGE ONTO THE GRAIN WAS OBSERVED USING THE IMAGE PROCESSING TECHNIQUE. AS THE RESULT OF THAT, FOR IMPELLER TYPE HUSKER THE TOTAL NUMBER OF THE GRAIN DAMAGED WAS MORE THAN THE ONE HUSKED BY THE CONVENTIONAL RUBBER ROLL TYPE HUSKER, HOWEVER THE DAMAGED AREA PER ONE DAMAGE WAS MORE LESS THAN THE LATTER ONE. THE DAMAGED AREA PER ONE DAMAGE WAS ALMOST EQUAL TO ONE THIRD TO ONE FOURTH COMPARED WITH RUBBER ROLL TYPE HUSKER. THE DAMAGED AREA FOR BOTH IMPELLER TYPE AND RUBBER ROLL TYPE ONE WERE ALMOST 10 % AND 40 % RESPECTIVELY OF THE TWO DIMENSIONALLY PROJECTED AREA OF ONE GRAIN.THE EFFECT OF HUSKING AND THE DAMAGE ON THE STORAGE WERE INVESTIGATED FOR TWO TYPES OF HUSKING METHODS, NO SIGNIFICANT DIFFERENCE WAS FOUND BETWEEN THEM.

进行了将叶轮式脱壳机应用于高含水率水稻的直接脱壳试验。结果表明，叶轮式脱壳机可成功安装并应用于实际脱壳作业，尤其适用于高含水率的大米。该功能在缩短采收和采收后加工工序方面具有很大的可能性和潜力。为了使糙米脱壳满意，必须认真考虑糙米的质量，但其中一些糙米可以用于饲养动物。因此，大米要用于动物性食品或加工产品时，这种脱壳系统可以立即应用，因为质量考虑不那么仔细。大米作为人类的主要食物，除了价格高外，对质量也有很高的要求。在高含水率大米的脱壳过程中，为了更好地保持稻壳，必须提高叶轮的外围转速，但脱壳率越高，稻谷（糙米）在脱壳过程中受到的冲击力越大，对稻谷（糙米）的伤害和破坏自然也就越大。本课题对两种脱壳方法进行了比较，并利用图像处理技术观察了脱壳对籽粒的损伤特征。结果表明，叶轮式脱壳机的籽粒破损总数大于常规胶辊式脱壳机，但每次破损面积小于常规胶辊式脱壳机。与橡胶辊式脱壳机相比，每损坏一次的损坏面积几乎是其三分之一到四分之一。叶轮型和胶辊型的破损面积分别约为一粒颗粒二维投影面积的10%和40%。研究了两种脱壳方法对贮藏效果的影响，结果表明，两种脱壳方法对贮藏效果的影响无显著性差异。少
