The expanding process involves heating the cleaned soybeans to facilitate soybean oil extraction. This can be achieved through mechanical pressing or by using solvents like hexane. Mechanical pressing involves physically pressing the soybeans to release the oil, while solvent extraction is a more efficient method for large-scale production.
Which solvent is used in soybean oil production?
Solvent extraction and expelling are the main processes used in soybean oil production. Hexane is currently the leading solvent in extraction , . This solvent has a high solubility for oil extraction, availability, low price, low boiling point, and heat of vaporization .
What process is used in soybean oil production?
During this step, some unsaturated fatty acids are converted into monounsaturated and saturated fatty acids to make them more stable to oxidation. Deodorization removes free fatty acids and volatile compounds from the feedstock . Solvent extraction and expelling are the main processes used in soybean oil production.
How much does soybean oil production cost?
Soybean oil production business can be started from mini or small-scale oil mill plant since it requires lesss investment cost. The small soybean oil processing plant designed by ABC 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.
