Soybean is an important source of vegetable oil and vegetable protein in the world. It can also be processed into soybean powder, soybean meal and so on. In a year with high precipitation, soybeans have a high moisture content and are prone to mildew and deterioration due to mold erosion and self-heating. Therefore, doing a good job of storing soybeans can avoid unnecessary economic losses. 1. Control the storage temperature. Temperature is an important factor affecting the storage of soybeans. The temperature is lower than 16% and it is not easy for insects. Therefore, the storage temperature of soybeans should be controlled below 16%. 2. Reducing the water content of soybeans. Water content is one of the most important factors affecting soybean storage. For agricultural products, there are mainly two methods to reduce the water content of soybeans. The first is the ventilation and ventilation method: that is, between soybean meal and earthworms. Leave gaps to facilitate air circulation, so that moisture easily lost. Soybean meal should be dumped for a certain period of time should be promptly poured. First pour large amounts of water, high impurities, lower levels of soybeans. When the dumplings, the top of the soybeans fell to the awkward Below, this will make the soybeans evenly distributed. The second is the use of drying precipitation method: suitable for high moisture content of soybeans. Drying drying method to prevent sun exposure, it is best to start in the early spring, and do a thin booth to turn over, reduce the production of explosive grain to ensure that the soybean products value. 3. Control the appropriate storage period. With the extension of the storage period, the fatty acid value in the soybean is increased, the oil is oxidized and rancid, resulting in deterioration of the soybean, resulting in odor, so the shelf life of soybean should be flexibly controlled according to its water content and use Soybeans with a water content of about 16% can be overwintering; water content of about 15% can generally be kept until June; moisture content of about 13% can be kept until July; water content of about 12% can be over Summer, but for germinating soybeans, the moisture should be maintained at about 11.5%.
