Background technique

Soybean is a crop whose seeds are rich in plant protein. The moisture content of soybean seeds harvested by a combine harvester is generally about 18% to 20%, and it needs to be dried. Usually, the drying process is divided into natural drying and artificial drying. Spread the threshed soybeans on the pre-prepared drying field for drying. The thickness of the seeds is generally about 10 cm. When the water content of the seeds is high, it can be appropriately thinner. On the contrary, when the water content of the seeds is not very high, it should be thicker. When drying, it should be turned frequently to make the seeds dry evenly. After about 4 to 5 days, when the seeds can be broken by biting with teeth, the water content will drop to the storage standard (about 12% to 13% water content).
