去除杂质:玉米收获时含有较多的未熟粒、破碎粒、糠屑等杂质,这些杂质吸湿性强、呼吸量大、带菌量多、孔隙变小,容易积聚湿热导致发热生霉和虫害,所以玉米收获后必须过筛除去杂质再入库贮藏,以确保安全贮藏粮食。干燥降温:安全贮藏玉米必须有适宜的水分和温度条件,玉米含水率12.5%,温度35℃左右,一般能安全贮藏。玉米收获后应充分暴晒或烘干处理,使其达到安全水分标准,贮藏中应注意通风散湿,新收获的玉米更应保持干燥和低湿条件,才 Removal of impurities: Maize harvested when more unripe grain, broken grain, chaff and other impurities, these impurities hygroscopicity, respiration, with more bacteria, smaller pores, easy to accumulate hot and humid lead to mold and pest infestation, so Maize must be screened to remove impurities after storage and storage, in order to ensure the safe storage of food. Drying and cooling: Safe storage of corn must have appropriate moisture and temperature conditions, corn moisture content of 12.5%, temperature 35 ℃, generally safe storage. Corn harvest should be fully exposure or drying treatment, so that it reaches the standard of safe water, storage should pay attention to ventilation and wetting, freshly harvested corn should be kept dry and low humidity conditions before
