THE MECHANICAL STRUCTURE DESIGN OF THE VICIA PEA SHELLER
摘要
蚕豆富含丰富的蛋白质和淀粉以及多种微量元素，可以为人体提供大量能量和营养，是重要的食品经济农作物。蚕豆在我国有悠久的种植历史，具有抗旱，高产，适应力强等特点。在中国的传统美食里蚕豆因其独特的风味、口感和加工方法，被用来制作发酵的酱菜；膨化类的香酥蚕豆；凉粉、罐头、芽豆等。
蚕豆的出口贸易需要对蚕豆进行深加工，如蛋白粉淀粉的制取，蚕豆膨化食品的加工，豆瓣酱的制作等可以大大提高蚕豆的经济价值。在提取蛋白、制作蚕豆淀粉和生产蚕豆的深加工产品时需要对蚕豆进行初步的加工。蚕豆的初加工包括蚕豆的脱壳、筛选、分级、轧碎和蒸炒等。因蚕豆的自身特点，对蚕豆的脱壳作为蚕豆初加工最难也是重要步骤之一，显得尤为重要。
脱壳后的蚕豆更容易加工，方便蛋白的提取，提高了淀粉的质量和饼粕的质量，同时使蚕豆食品更加美观。最早的蚕豆脱壳只有手工剥壳，手工剥壳效率低，对手指伤害大，不利于蚕豆的筛选品质不一。蚕豆的机械脱壳效率高，减轻了农民的工作量也提高了农民的收入，因此蚕豆脱壳机的研发迫在眉睫。
好的脱壳机不仅要证加工效率，良好的机器运转，蚕豆的脱壳率完整度还需要考虑脱壳机的成本。因此脱壳机的设计就尤为重要，有合理的设计才能生产出高质量的
受欢迎的机器。

Abstract
Faba bean is rich in protein and starch, and a variety of trace elements. It can provide a lot of energy and nutrition for the human body. It is an important food economic crop. Faba bean has a long history of planting in China. It has the characteristics of drought resistance, high yield and strong adaptability. In China's traditional food, broad beans are used to make fermented pickles for their unique flavour, taste and processing methods; the puffed crisp broad beans; the cold powder, the canned bean, and the bean sprouts.
The export trade of broad bean needs deep processing of the broad bean, such as the preparation of protein starch, the processing of the expanded food of the broad bean, the production of the bean paste and so on, which can greatly improve the economic value of the broad bean. In the process of extracting protein, making broad bean starch and producing deep processed products of faba bean, we need to make preliminary processing of faba bean. The initial processing of faba bean includes bean hull shelling, screening, grading, crushing and steaming. Because of the characteristics of faba bean, the shelling of faba bean is one of the most difficult and important steps in the initial processing of faba bean, which is particularly important.
The bean after shelling is easier to process, facilitate the extraction of protein, improve the quality of starch and the quality of cake, and make the faba bean food more beautiful. The husk of the first faba bean can only be shelled by hand, the efficiency of manual shelling is low, and the damage to fingers is large, which is not conducive to the different quality of Vicia faba. Faba bean has high efficiency of mechanical shelling, reduces the workload of farmers and raises the income of farmers. Therefore, the research and development of faba bean sheller is imminent.
A good sheller not only requires processing efficiency, good machine operation, but also needs to consider the cost of shelling machine. Therefore, the design of sheller is particularly important, and reasonable design can produce high quality.
A popular machine.
