Storage methods of Corn

The key to safe storage of corn is to improve storage quality and reduce grain moisture. As there are great differences in air temperature and humidity in different places, corresponding storage measures should be adopted according to the specific local conditions.

? Grading: enter the warehouse according to different moisture content. Corn should be stored separately according to different water content and different grades when entering the warehouse. Lay a preliminary foundation for safe storage. Corn with high moisture content should be dried before storage.

? Low temperature sealing: according to the storage characteristics of corn, it is suitable for low temperature and dry storage. There are two methods, one is dry sealing, the other is cryogenic freezing sealing. The corn harvested in the southern region can be fully dried and sifted into closed storage after it is reduced to a safe moisture content. Corn in northern China is limited by air temperature after harvest, so it is very difficult for high moisture corn to fall to safe moisture. In addition to drying and precipitation, low temperature freezing can be used for airtight storage. The method is to make use of the cold and dry weather in winter to cool down, and the grain temperature can drop below-10 ℃, then sift through the frost and clear the miscellaneous, and store it in a closed warehouse on a low temperature and sunny day. But this is only temporary and the corn must be dried or dried before it warms up or rains in the spring.

Corn ear storage: corn does not thresh, ear storage is a relatively mature experience, which has long been widely used by farmers in our country. Due to the large porosity in the ear pile (up to 51.7%), good ventilation conditions, and the low temperature season, although the ear respiration intensity of high moisture corn is still very high, it can also maintain the balance of thermal energy metabolism, and the change of pile temperature is small. Under the condition of long-term ventilation in winter and spring, the corn can be dried gradually. When the moisture content drops to 14.5%-15%, it can be threshed and transferred to grain storage.
