Threshing consists of separating the beans from the portion of the plant that holds them. Nowadays, most of the soybeans are harvested and threshed simultaneously by using modern combines. Threshing can also be done by hand, with simple tools, with the help of vehicles, or with simple handy machines or motor operated, Figure 11. Whatever the system used, it is very important that threshing be done with care. Otherwise, this operation can cause breakage of the beans or protective hulls thus reducing the product’s quality and fostering subsequent losses from the action of insects and moulds.
