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.
What is a complete soybean oil mill plant?
Complete soybean oil mill plant is usually designed with seeds pretreatment section, oil processing section, oil refining section and oil filling section. According to oil extraction methods, soybean oil production can be divided into mechanical oil pressing and solvent oil extraction.
How much does a soybean oil processing plant 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. Soybean Oil Processing Flow Chart
What is solvent extraction process in soybean oil extraction?
The solvent extraction process is a common method used for soybean oil extraction. The aim is to use a solvent for dissolving a target solute, and wash it out of the solid plant component. The processes involved at this stage are provided below. Soybeans are first cleaned and cracked.
