Small Scale Soybean Oil Refinery Machine in Nigeria

To get a small-scale soybean oil refinery in Nigeria, you can buy equipment from specialized manufacturers QIE Machinery, who offer customizable batch or semi-continuous refining units with capacities from 1 to 20 tons per day. The cost will vary significantly based on the specific machinery, its capacity, and whether it includes preprocessing, pressing, and a refining line. A small oil processing line typically involves cleaning, flaking, cooking, pressing, and filtering, with the refining steps including degumming, deacidification, decolorization, and deodorization.

You can choose suitable soybean oil refining equipment according to your processing capacity.

Batch type soybean oil refining plant:This process is to refine the crude oil batch by batch, it is more suitable for small capacity like 1-2-3-5-10TPD.

Refine Crude Oil:

palm oil, cottonseed oil, corn germ oil, peanut oil, soybean oil, sunflower seed oil, rapeseed oil, rice bran oil, coconut oil,animal fats and oil etc.

Soybean Oil Refinery Plant Process (1~20TPD )

Crude Soybean Oil – Degumming – Deacidification – Decolorizating – Deodorizating – Soybean Oil

Crude soybean oil can be obtained from soybean extraction plant or soybean oil pressing plant. However, crude soybean oil still have some impurities that is insoluble or soluble. For cooking, these impurities must be removed from the crude soybean oil.

Degumming is to remove impurities, like phospholipid, gum, and protein, and other, by adding hot water or dilute acid, alkali, salt and other electrolyte solution into the crude soybean oil. As a result, the colloidal impurities absorb water, expand and coagulates, finally are separated from soybean oil.

Deacidification is to add alkali to neutralize the free fatty acids (FFAs) and lead to the formation of fatty acid salt (soap) and water. Then, some impurities are absorbed in soap and all sank and separated from the soybean oil.

Decolorizating is to adsorb the pigment and other impurities in crude soybean oil by adsorbents and remove the adsorbents and impurities through filtration to achieve the purpose of decolorization and purification.

Deodorizating is to remove the smelly substance from soybean oil. The most wide used method of deodorization for soybean oil refinery plant is vacuum deodorizating.

Parameters of crude soybean oil refinery machine

Soybean is one of the annual plants of leguminosae, and it produces about 50% of the world’s oil. The oil contend of soybean is about 18%. Soybean oil is one of the most commonly used cooking oils in the world. It is an important source of unsaturated fatty acids for human body, which can lower cholesterol, and also has an auxiliary therapeutic effect on hypertension and cardiovascular diseases. Through refining, soybean oil is mainly used for cooking. But, how the soybean oil is refined?

How the soybean oil is refined?

1.Pour the filtered oil into the first mixing tank(Note: the height of oil must over the heating tube)

2.Turn on the mixing switch ,the rotate speed at 45-55 RPM(revolution per minute ) (note: there is a nob on the side of the electricity box to adjust the rotating speed).

3.Turn on the heating switch,set the temperature of temperature-controlled meter to 62 degrees.

4.Pour the prepared citric acid solution into the stirring tank slowly when the temperature reaches 62 degrees (the ratio of citric acid to water is 50kg water to 2.5kg citric acid, and the ratio of oil to citric acid solution is 50kg oil and 0.5-1.5kg citric acid solution, the temperature of water must be between 80 -100 degrees)

5. Turn off the heating and stirring switches after 30 minutes . After 30-60 minutes of natural precipitation, remove impurities from the rubber outlet until clean oil is discharged from the rubber outlet, then close the rubber outlet.

6.Turn on the stirring and heating switches , set the temperature to 110 degrees. Wait 30-60 minutes after the temperature reaches 110 degrees,take a small sample to test in the pot,confirm if there is any water in the oil. (Note: the method of testing water content:pour the refined oil to pot ,then heat the pot. If there is no water in the oil, you cannot hear the noise of water.) If still have water, continue to heat until the sample have no water. Then turn off stirring and heating switches.

7.When the oil temperature naturally drops to about 80 degrees, set the oil pump switch and filter the oil into the filter tank. (Note: At the beginning of the filtration, a part of mixed oil will come out. Note that there is a three-way valve under the box. When make the wrench and the pipe form an angle of ninty degree,he oil will return to the first stirring tank.Until the mixed oil is clear,make the wrench and the pipe in a straight line,the oil will enter the finished product tank).

Soybean oil is one of the most widely consumed edible oils in Nigeria. Meanwhile, the soybean oil industry offers lucrative opportunities for Nigerian entrepreneurs.In recent years, Nigeria has attracted a growing number of investors interested in its edible oil processing sector, particularly soybean oil. However, turning an investment intention into a fully operational soybean oil production plant is far more complex than expected.
