The soybean oil will be in extraction process after oil crushing

What equipment is required for extracting soybean oil? What are the specific extraction steps?

The extraction process of soybean oil is similar to other oilseeds. By using advanced production line equipment and following operating procedures such as cleaning, crushing, softening, embryo pressing, and finally pressing, soybean oil can be easily extracted. So, what equipment will be used for the extraction process of soybean oil? What are the specific production steps? Let's take a look together.

Firstly, after receiving the oil raw materials, we need to clean the oil. The equipment used in the cleaning process mainly includes vibrating screens, magnetic separators, and stone removal machines. This is the most fundamental step in the refining process, removing impurities from the oil and ensuring the quality of the oil.

Then, a crusher is needed to reduce the particle size of the raw material, which is beneficial for subsequent rolling. Moreover, the particle size of the raw material decreases, increasing the contact surface area of the oil, making it easy to adjust temperature and moisture.

Soybeans have an oil content of 16% -24%, making them a low oil content crop with low water content. Therefore, softening must be carried out during the pre-treatment process. The equipment used in this step is a softening pot, which is used to increase the moisture content of the oil raw material, improve plasticity, and facilitate the later rolling of the embryo.

After softening, it is necessary to use a rolling machine to roll the oil, which mainly changes the raw material from granular to thin flakes, damages the structure, shortens the oil circuit, and improves the oil production efficiency.

Steam frying is a very important step in the extraction process of soybean oil. By steaming and frying, the temperature and moisture of the oil can be adjusted to the optimal state, making it suitable for high temperature and low moisture extraction. The equipment used for steaming and frying is mainly a steaming and frying pan, which transforms raw embryos into mature embryos.

After the above steps, the oil has been adjusted to its optimal state and can be squeezed. After pressing the oil, we can obtain soybean crude oil, and if there is a high requirement for oil quality, we can continue to refine it.
