First, the storage technology of corn 1, the original water is generally larger, uneven maturity: the corn production areas in the harvest season, due to weather and other factors, so that the original corn water differences. The maturity of corn is also very uneven. The top grain of the ear matures slowly, has a large amount of water, and is easily damaged during threshing. 2. The embryo of corn is large and its breathing is vigorous: corn embryo accounts for about one-third of the grain size, accounts for 10%-12% of the grain weight, has loose tissue, contains more protein, soluble sugar and fat, and has a large amount of respiration. The respiratory intensity is about 8-11 times that of wheat, which makes corn easily absorb moisture, mold, acid, and bitter during storage. 3, corn embryos containing more fat, apt to rancidity: corn embryo contains 77% -89% of the fat in the whole grain, the embryo's fatty acid value is always higher than the endosperm, rancidity also starts from the embryo. 4. Maize embryos are susceptible to mildew: As the embryonic parts are rich in nutrients and the amount of microorganisms adheres, the embryo is the site where insects and molds first become harmful. After the embryonic part absorbs moisture, at a suitable temperature, molds multiply and begin to mold. Second, the ear of corn storage method. The ear of corn is generally stored in a specially prepared container. The shape of the container is rectangular and round. Rectangular space is 0.5-1 meters from the floor mat, the length is determined by the topography, and the width is not more than 2 meters. It is made of wood or straw, etc. The round bottom pad is 0.5 meters in diameter and 2-4 meters in diameter. 3-4 meters, surrounded by vitexes or straws. During storage, care should be taken to keep the upper lid well, prevent rain and snow from entering the warehouse, and select the dry and ventilated location of the foundation. Maintain a certain distance between the warehouse and warehouse to facilitate ventilation. When the moisture content of the ear is low, threshing can be promptly avoided, so as to avoid mildew or rancidity due to moisture absorption in the wet season. If the ear moisture is uniform when entering the warehouse, and within the safety standards, generally there will be no heat and mildew. After warehousing, attention should be paid to inspection. Once heat and humidity occur, it is necessary to cool down and cool down in time. Third, the storage of corn kernels. The dried corn kernels can be stored or stored in the warehouse. Stacking height should be 2-3 meters. Generally, the moisture content of corn is below 13%, and the grain temperature does not exceed 30°C. It is safe to pass the summer. If the new corn kernels are stored, they can be ventilated and tipped over about 1 month after the warehousing, or when the autumn and winter seasons are exchanged, in order to distribute the damp heat and prevent sweating. For corn kernels that have been dried and the moisture content is reduced to below 14%, cryogenic freezing can be performed in winter and the gland closure work can be done to facilitate safe summerization.
