为了保证长期安全储存,大豆的含水率通常要降到13%。才能入库储藏。用塔式干燥机干燥时,豆粒的受热温度不超过30~35℃,干燥介质温度为60~80℃,处理时间为40~45 min;采用双级干燥时,第一级干燥介质温度为90℃,豆温为25℃,第二级的干燥介质为80℃,豆温35℃。大豆一次干燥降水不低于3%~6%,降水速率约为3%/h。(1)干燥贮藏法:一是用日光暴晒;二是用设备烘干。(2)通风贮藏:大豆在贮藏过程中,要保持良好的通风条件,使干燥的低温空气不断地穿过大豆籽粒间,可以降低温度,减
In order to ensure long-term safe storage, the moisture content of soybean is usually reduced to 13%. To storage storage. Drying with a tower dryer, the beans heated temperature does not exceed 30 ~ 35 ℃, the drying medium temperature is 60 ~ 80 ℃, the processing time is 40 ~ 45 min; the use of two-stage drying, the first drying medium temperature of 90 ℃, the temperature of beans is 25 ℃, the drying medium of the second level is 80 ℃ and the temperature of beans is 35 ℃. Soybean a dry precipitation of not less than 3% to 6%, the precipitation rate of about 3% / h. (1) dry storage method: First, exposure to sunlight; the second is to use equipment drying. (2) ventilation and storage: Soybean in the storage process, to maintain good ventilation conditions, so that the dry, low-temperature air through the soybean seeds, can reduce the temperature, reduced
