Squeezed soybean oil is one of the common soybean oils, and is welcomed by consumers because of its pure fragrance and rich nutritional value. The raw material for the production of pressed soybean oil is soybeans, which are oil plants with low oil content, with an oil content of 16-24%. So how to produce pressed soybean oil from soybeans? What is the processing process of soybean oil pressing? Next,
1. Clean up
Soybeans used for soybean oil crushing production will contain some impurities, such as dust, sand, small stones, metal impurities, husks, bad grains, etc. These impurities will not only affect the soybean oil squeezing process, but also wear the soybean oil squeezing equipment and reduce its service life. So it is necessary to use cleaning equipment to remove these impurities.
2. Broken
Soybean grains are larger, which will affect the rolling and pressing of soybeans, so the soybeans must be processed into pieces with a crusher, which increases the surface area of the soybeans, and the temperature and moisture of the soybeans are more evenly transferred when the soybeans are softened, and the softening effect is obtained. promote.
3. Steam and stir fry
Steaming and frying is an important process in soybean oil squeezing and processing. It mainly changes the internal structure and state of soybeans through the effects of temperature and moisture, so as to accumulate oil and increase the rate of squeezed oil. At the same time, steaming and frying can also adjust the elasticity and plasticity of soybean cakes and change the quality of soybean cakes.
4. Squeeze
Squeezing is the process of extracting soybean oil from soybeans through mechanical extrusion of an oil press. Because of the previous series of pretreatment processes, the temperature, moisture, and structure of soybeans have reached a good state suitable for pressing, so the pressing process is smoother and the pressing efficiency is also improved. The equipment used in the pressing is an oil press. Benteng machinery equipment can be equipped with one or several oil presses according to customer needs and soybean processing capacity.
5. Filter
Commonly used machines for filtering are plate and frame oil filter, vacuum oil filter and air pressure oil filter. The plate and frame oil filter is often recommended, which is cheap, easy to use, and clean.
Simple process: drum roaster-oil press-plate and frame oil filter
Complex complete process: vibrating screen-conveyor-crusher-drum wok-conveyor-oil press-plate and frame oil filter
Soybean meal: The value of soybean meal is very high. Generally, we can use soybean meal as animal feed, and secondly, we can eat it as soybean hull.
The above is the detailed production process of soybean oil pressing. The engineers of Benteng Machinery will customize the soybean oil squeezing production plan according to the specific situation of each customer, and equip the corresponding soybean oil processing equipment, so that the customer’s investment budget can be reasonably used. If you are preparing a soybean oil crushing production project and are looking for a soybean oil processing equipment manufacturer, then you can contact us, and the Benteng Machinery team will serve you wholeheartedly.
