What Is The Steps To Make Soybean Oil?

Soybean oil is a healthy, cholesterol-free edible vegetable oil with a light and clean flavorthat is commonly used for cooking. The oil is 60% polyunsaturated fat and 24% monounsaturated fat, according to the National Soybean Research Laboratory, making it a heart healthy oil. Today, making your own soybean oil is very easy, it only need several steps so you can start an oil business in your farm or your village, etc.

The complete soybean oil making process is :
Soybean seeds→Cleaning →Crushing→Softening→Flaking→Oil Pressing

Step 1  Cleaning Soybeans

Before you start making soybean oil by automatic soybean oil press, soybean seeds should be cleaned, remove any foreign matter, including leaves, twigs or small stones from beans by certain cleaning equipment, such as destoner and TQLZ high-frequency vibration cleaning sieve, etc., finally make its impurity content less than 0.1%.

Step 2 Crushing Soybeans

After cleaning, soybean seeds should be crushed by crushing machine,It is used for crushing soybean into small pieces (The degree of breaking up to 2 - 4 is the best), which can help to extract more oil from the seeds.

Step 3 Softening Soybeans

Soybean seeds should be softened by softening machine, this is a special step for soybean oil making. The water content of soybean was controlled at about 15% and the softening time was 40-50 minutes..This step improves the ductility of soybean. Then the flakes will be thin and not fragmentary. It can reduce the fines content effectively. 

Step 4 Flaking Soybeans

Soybean seeds also should be flaked by flaking machine,this machine can be made the
soybean to 3mm-5mm flakes. The benefits of soybean flaking: one is to destroy the cell tissue to make the oil flow easily from the cell, the other is that the granular oil seed is rolled into thin slice, the surface area is increased, and the oil area is increased, then the distance from the oil to the embryo is greatly shortened.

Step 5 Frying Soybeans

After flaking, put the soybean seeds into the roaster for frying, when the soybean moisture in the range of 1.5-2.8%, the temperature between 100 to 110 degrees, then it can begin to press the soybean oil, the cake thick control in the 1-1.5 mm or so.

Step 6 Pressing Soybeans

Soybean Pressing more use of screw soybean oil press. In the squeezing process, you should pay attention to control the temperature of the press chamber to prevent the temperature is too high or too low, then affect the oil yield.
