Turnkey Projects of Soybean Oil Production - Oil Pressing Section

Data from the US Department of Agriculture states that soybean oil is the most popular and commonly used cooking oils throughout the world. As per a study by University of California – Riverside, this oil accounts for more than 90% of all seed oil produced in America. Reasons behind its increased popularity include its health benefits and price. This oil is rich in Omega-3, Omega-6 and Vitamin E.

Small Scale Soybean Oil Production Plant

Have you ever wondered what's a soybean oil mill is about and how to set up a small scale soybean oil production plant? If so, this article will is for you. In this article, we will discuss the activities in a soybean production. Don’t worry this article will not be too technical, we have made it easy for you to understand without using much of technical jargon.

Soybean Oil Production Process

Production of high soybean oil is the main objective of a soybean oil production plant. Thorough knowledge of the technical system of the plant and disciplined operation are must to produce quality soybean oil.

Storage and Crushing

As with any other seed oil processing plant, storage is a very crucial aspect. Soybeans are received and stored in specially prepared silos in the soybean oil mill plant. Before they are stored, they are thoroughly cleaned and dried. Stray metallic particles are then removed from the beans using "Tramp Iron Removal" where magnets are placed strategically to remove materials such as nails, staples, baling wire, etc. Apart from this, other methods are used to remove the foreign material. Soybeans are then stored under necessary temperature and moisture.

Dehulling

Dehulling the soybeans is the next step and some common types of dehulling methods include:

• Conventional Dehulling - soybean tempering followed by cracking and screening;
• Hot Dehulling - a fluidized bed is used to achieve the desired moisture level before cracking;
• Esher Wyss Dehulling – here soybeans are first cracked into two pieces and then required moisture is attained using a fluidized bed;

The main purpose of cracking is to get the right sized flakes for oil extraction. After dehulling, the hulls are separated from the meats.

Conditioning and Oil Extraction

In order to effectively extract the oil, conditioning is used to soften the meats. The conditioned flakes are fed through a pair of smooth surface rolls, where they get crushed and the crude soybean oil drains out.

The soy meal is collected separately and toasted to deactivate urease and trypsin inhibitor. Subjecting the meat to appropriate temperature gives a good quality soy meal. This meal is stored separately and used for various purposes and most importantly for animal feeding.

Once the crude oil is collected, it is set to cool at 65℃ before exposing it to air as at high temperature, oxidative degradation will occur. Then the oil is sent for refining where this crude oil will be converted to usable cooking oil.

Soybean Oil Refining

The first step of refining is called as Degumming where soybean oil which has high amount of hydratable phosphatides are neutralized. Then caustic refining is done to remove fatty acids, phosphatides and other materials. The next step involves removing oxidation products, triglycerides and reducing color pigments. Finally deodorization is done where volatile components such as pesticides, glycerol and free fatty acids are removed.

We can supply customized business plan for both mini scale, small scale, medium scale and full scale seed oil production. Just contact us and tell us your needs. We are always at your services!

The quality of the oil depends on the quality of the refinery process. Many contaminants may occur and trans fatty formation may occur during the refining process. So to prevent such kind of issues proper maintenance and professionalism is very important at the soybean oil production plant.
