Rapeseed is a major bulk oil resource in China. To improve the storage of rapeseed can reduce waste and improve efficiency. According to the experience accumulated in actual storage in various places, the newly harvested rapeseed should be stored in stages. The specific methods are as follows: The rapeseed with water content below 9% and impurity content no more than 3% is suitable for longer-term storage. Therefore, in the case of storage, the stack height should be 1.8-2.3 meters; when packing and storage, stacking should be 12 packages high. For rapeseed with moisture content of 10% to 12%, only short-term storage. Rapeseed with a moisture content of more than 12% must be stored in the sun before storage. It is worth noting that: when rapeseeds are suntanned, they must master the method, that is, they must be allowed to dry in the drying area before drying in the shop. Otherwise, the rapeseed is easily degenerated, the oil is crushed, and the dark green kernels are degenerated. Specific performance; After drying the rapeseed, it must also be allowed to spread its heat and cool after storage, otherwise it will form a "dry burn", seriously affecting the oilseed rapeseed oil and oil quality. Another storage method of rapeseed is ventilation cooling storage method. The essential method of this method is to reduce the storage temperature and storage moisture of rapeseed by ventilation. However, ventilation must be performed in conjunction with the temperature and humidity conditions. Do not operate blindly. It has been determined that rapeseed is stored in an environment with a relative humidity of 80%, and the increase in the moisture content of rapeseed itself is generally around 10%. Therefore, the greater the relative humidity in the storage environment, the more likely rapeseeds are damaged. Rapeseed should not only pay attention to ventilation during the storage process, but also can not ignore the environment's closed moisture-proof to keep dry and low temperature.
