Soybean oil production line
Soybean is generally cultivated in the tempered region with water availability. Soybean oil can be extracted from soybean by solvent extraction plant, the demand of soybean oil is increasing rapidly, so there is good scope for new entrants.
Soybean oil is high in poly and monounsaturated fats, low in saturated fats and trans fat free.
Even after extraction, soybean oil retains its natural antioxidants, affordable, versatile and mild, soybean oil is used in over 75% of all commercial food production.
Soybean oil production line inlucdes: soybean seeds, cleaning, dehulled, heated, cracked ,flaked, extruded before entering the press
Flow Chart for Soya Oil Production/Making
Soybean Oil Solution: The process of soybean oil making mainly include pretreatment, extraction and refining.
1.Preparation and Dehulling
The first step in processing soybeans is to properly prepare the soybean for dehulling. This step typically involves using magnets to remove metal and screening to remove impurities that can interfere with the dehulling process. Next, hulls are moved to both increase the protein content of the final meal product and also to improve the efficiency of the solvent extraction process. Finally, mechanical rollers are used to make thin flakes and rupture the cells containing the soybean oil.
The extraction process uses hexane or other solvents to wash the soybean oil from the prepared soybean flakes. The design of the equipment varies so that Crown can optimize the amount of solvent and bed depth needed to efficiently wash the flakes, the contact time of the solvent and flakes, and the power and utilities needed to run the equipment. Soybeans are processed with the Three-type Extractors(Retocel,Loop and Chain).
Once the oil has been removed by the solvent, the solvent must be removed from both the flakes and the soybean oil. For the flakes, heat and steam are used to strip and recover the residual solvent. For the soybean oil, a distillation system is used to recover the solvent. The desolventized flakes are now a product and ready for sale as a good source of protein. The soybean oil can be further refined from a crude product to an edible product.
4.Oil Refining and Processing
Extracted and desolventized soy oil must be further processed to make an edible product. Edible oils are refined to improve the flavor, odor, color and stability using processes that degum, neutralize, bleach and deodorize the oil. These refining processes remove contaminants such as phosphatides, free fatty acids and pro-oxidants. Further processing of oils and fats is sometimes desired. Some oils are winterized or dewaxed and some are modified to change melting characteristics. Byproducts may be further processed to create value-added products or reduce costs.
