Problems solved by technology

[0004] The existing soybean storage method is mainly to dry soybeans and store them in the warehouse, but this method not only has high labor costs, but also has low soybean drying efficiency, and the temperature and humidity of the warehouse where soybeans are stored are not easy to control, which easily leads to moisture, mildew and deterioration of soybeans

Embodiment 1

[0020] After the soybeans are harvested in the place of production, the soybean plants with pods are planted upside down and dried in the field for 2 to 3 days to facilitate post-ripening and air-drying. Then the fruits are picked and spread out to dry the fruits. The moisture content measured by the rapid moisture meter reaches 30%; Before entering the warehouse, the soybeans are initially cleared, hot-air dried, and tempered to complete the initial treatment; then, the soybeans after the initial treatment are dried by radio frequency and microwave, and then slowed or blast-dried to reduce the moisture content. to 11%; the output power of the radio frequency equipment is 5kW, and the frequency is 13.56MHz; the output power of the microwave equipment is 10kW, and the frequency is 915MHz. The temperature is less than 35°C, and the ratio of drying time to slowing time is 1:6; finally, the processed soybeans are sent to a cold air store with a moisture exhaust fan for storage, and...

Abstract

The invention provides a soybean storage method which comprises the following steps: S1, preliminarily cleaning soybeans before warehousing, performing hot air drying, tempering, and thus finishing initial treatment; S2, performing radio frequency and microwave drying treatment on the soybeans subjected to initial treatment, and performing tempering or forced air drying, so that the moisture content is reduced to be 11-13 percent; and S3, feeding the treated soybeans into a refrigerated depot section with a moisture removal fan for storing, controlling the temperature of the refrigerated depot section to be 8-15 DEG C, and controlling the relative humidity to be 70 percent or below. According to the soybean storage method disclosed by the invention, the labor intensity of drying the soybeans is reduced, the soybean drying efficiency is improved, the temperature and humidity control precision during soybean storage is improved, and the condition that the soybeans are affected with damp to get mildew and go bad is avoided.

Description

technical field [0001] The invention relates to the technical field of miscellaneous grain storage, in particular to a soybean storage method. Background technique [0002] Soybeans (generally including yellow soybeans and black soybeans) have round grains, smooth seed coats, hard grains, and strong resistance to insects and mildew, but damaged soybeans are easy to deteriorate. Soybean grains are rich in protein and fat, and are easy to absorb moisture when the air humidity is high. After being affected by high temperature in summer, they are easy to change color and taste, and serious oil immersion occurs. At the same time, high temperature and high humidity can easily reduce the germination rate of soybeans. [0003] When the moisture content of soybeans is more than 13%, as the temperature rises, the bean grains will first become soft, and then the color of the two cotyledons near the embryo will turn red, commonly known as "red eye". , when severe, the cotyledons are w...
