Install a Soybean Solvent Extraction Plant if you want to start a business of producing soybean oil solvent. The soybean seed are pretreated and then mixed with solvent in the solvent extraction process. Solvent liquid transfer is the process by which soybean oil is extracted. This automatic plant can be installed in an existing unit. Once commenced, it can be used for batch or continuous soybean oil extraction process. Clean, undamaged soybean seeds that have right moisture must be fed into the plant. The quality of oil extracted from the soybeans can be measured by the colour and free fatty acids. This process of soybean oil extraction using a soybean solvent extraction plant generates soybean meal as a by-product which can be used for cattle feeding.
