According to oil extraction methods, soybean oil production can be divided into mechanical oil pressing and solvent oil extraction. And crude soybean oil extracted from both mechanical or solvent has impurities and should be refined through a series of oil refining process to get edible refined soybean oil.
How much does a soybean oil processing plant cost?
The small soybean oil processing plant designed by Hongde Machinery, with capacity 5~20 tons per day may need at least $7,500. But the final exact cost should be confirmed with your sales or engineers. Soybean Oil Processing Flow Chart Above listed the most efficient soybean oil processing flow chart.
What solvent is used in soybean extraction?
In solvent extraction, flaked soybeans are washed with hot solvent, typically hexane, to separate the solids from the fats. Multiple washes dissolve the oil and carry it away. This oil solvent combination is also known as the miscella. The remaining material is the wet meal and solvent, also known as the marc.
Why is soybean extruding important?
The most important function of soybean extruding is to destroy cell structure for easy oil extraction, blunt all kinds of enzymes, improve the oil yield, increase oil output and reduce solvent loss.
