Many customers who open oil mill plants and do grain and oil processing are most concerned about the production problem of soybeans. According to the actual processing data, 15 to 22 jin of soybean oil can be squeezed out from 100 jin of soybeans.

The oil yield of soybean is not fixed, and it fluctuates widely. The specific oil yield mainly depends on multiple factors such as soybean variety, processing technology and storage conditions.

Variety determines the upper limit of basic oil production.

The oil content of different soybean varieties is obviously different. Ordinary domestic edible soybean has high protein content and low oil content, which is suitable for physical crushing in local oil mills. However, high-oil special soybeans and imported soybeans are full of particles, have higher oil content and produce more oil, which is more suitable for mass production. Dry, immature or mixed varieties will directly reduce the oil output.

Processing technology is the core key.

The same soybean raw materials, different processes have great differences in oil production effect. Traditional small-scale physical pressing produces less oil; However, the leaching process used in large factories can extract the residual oil from soybean meal to the maximum extent, and the maximum oil output can reach 20-22jin.

Storage conditions affect the stability of oil.

Although soybeans are resistant to storage, moisture regain will lead to excessive moisture and poor oil production during pressing; Soybean stored for too long, oxidized or moldy, loses oil and affects the taste of oil products. Only dry, ventilated, low-temperature and moisture-proof standard storage can keep the oily state of soybeans stable.

In short, the variety is based, the technology is limited, and the storage is stable. As long as the oil processing plant optimizes the high-oil soybeans, matches the appropriate technology and standardizes the storage of raw materials, the high-efficiency and stable soybean oil yield can be maintained for a long time.
