1, storage technology of rice 1 storage characteristics Avoid high temperature: rice in the sun under strong sunlight or drying at higher temperatures, can increase the waist rate and discoloration, reduce food value. When paddy is stored at high temperatures, it may also cause moisture stratification and knot formation, resulting in heat and mildew. Easy to germinate: The new harvest rice has strong physiological activity, easy to self-heat after entering the warehouse, so that the grain temperature rises, resulting in moldy upper grain condensation. Temperatures increase in the spring of next year, and the top of the grain piles are prone to condensation and mildew. The site of condensation or leakage of grain piles, due to increased moisture, prone to shoot mold, commonly known as bud rotten. 2 Storage methods: Rice is a kind of grain suitable for long-term storage. The respiration of rice is generally high in the first 1 to 2 years of storage, and then gradually decreases and tends to be stable. Rice is generally stored in warehouses. Water and temperature should be controlled when entering the warehouse, moisture is about 14%, and temperature is below 25°C. 2. Storage technology of rice 1 Storage characteristics: After rice loses the skin protective layer, the nutrients are directly exposed to the outside and sensitive to the effects of external temperature, humidity, and oxygen. The hygroscopicity is strong, the amount of bacteria is high, and pests and molds are easy to direct. Harm, and easily lead to accelerated metabolism of nutrients. The fat contained in lotus root starch is easily oxidized and decomposed to form fatty acids, which increases the acidity of rice. Due to the existence of the above-mentioned unfavorable factors, the aging of rice and the speed of mildew are more prominent. The rice should be stored at low temperature and should not be directly blown or suddenly cooled. It is only possible to slowly cool the temperature and slowly dry and dry in a low-temperature environment. It is not suitable for high-temperature drying or direct sunlight exposure. 2 storage methods: rice is best stored at low temperature. The following points should be noted during storage. Strict control of moisture: Safe moisture stored in rice is less than 13%. The safe moisture can also be adjusted according to the temperature. In summer and autumn, the temperature is below 13% when the temperature does not exceed 35°C. The temperature is below 14% when the temperature in spring does not exceed 20°C, and it can be relaxed to 15%～16 when the temperature in winter is below 10°C. %. Remove smut powder, pest control and mildew: rice should be checked during storage. Found that there is a precursor to heat and mildew, it should be timely airing. When glutinous rice should be removed, the glutinous rice powder should be removed again to increase the storage stability of rice. Natural low-temperature storage: In order to make the rice safer in summer, the natural cold in winter and early spring can be used to cool and dehumidify the rice, and close the warehouse before entering the summer to reduce the impact of high temperature and humidity on the rice.
