How is soybean oil extracted?

Soybean oil processing machine is necessary to obtain soybean oil from soybean. Some processes in soybean oil mill include: Soybean pre-treatment and pre-pressing, solvent extraction plant and soybean oil refinery plant:

In the first phase, soybean is being cleaned, hulling, crushing, softening, flaking, cooking, pressing and filtering. Different types of pressing machines are used for this process, according to the amount of output and according to the type of seeds you are using to obtain the fixed oil. As a rule the soybean pre-treatment and pre-pressing workshop includes a cleaning machine, screw elevator, a cooker, a crusher, a filter press. It all depends on a model and design, which various companies can offer you. All the oil seeds are going into a cleaning area and following the steps for each step to be ready for the next step.

The second phase consists of extracting, removal of solvent nature, evaporation, stripping and solvent recycling. The extraction process is the process, which means separation of oil from seed. Pre-processed seeds are treated with solvent in a multistage counter current process. The oil and solvent are then separated by distillation. The solvent extraction is going into the recycle process and the crude oil is ready for the next step. This process will maintain production safety and provide a good quality.

The final stage of the vegetable oil refinery line provides degumming & deacidification, decolorization, deodorization etc. At the stage of degumming the oil separated from the sand, it is then freed from free-fatty acids and dyes. The odor and odor are then removed from the oil, as many seeds have a special smell and odor, which many people do not like. So, it will allow to achieve high quality production of oil.

The small scale soybean oil production line is very comfortable for small family business. Only 2-3 persons are required for that line. The line also requires a small amount of space for machines, which are of different design from different producers such as cookers, soybean oil press machines, oil filter machines and so on, but make all three processes, as the big plants are doing, and give it a wonderful production.


Small-scale soybean oil production line is a great opportunity for workers to obtain high-quality vegetable oil inside a small family factory, without using so much space, time and sources.
