20-350 Tpd Continuous Edible Soybean Oil Extraction Machine And Refining Plant With 6 Step Method

20-350 Tpd Continuous Edible Soybean Oil Extraction Machine And Refining Plant With 6 Step Method is a general term for the removal of solid impurities, free fatty acids, phospholipid, colloid, wax, pigment and odors in vegetable oils. The presence of impurities contained in crude oils not only affects the use value, the safety storage of crude oil, but also cause difficulties for the deep processing crude oils. Edible oil refining is not only removes all the impurities out from the crude oils, but also refines harmful impurities, such as, gossypol, protein, lecithin, mucus, water and more. In this way, the edible oils can have better storage, industrial applications and cooking purpose. However, some beneficial substances, such as tocopherol, sterol and more, will be maintained.

Pretreatment of soybean

Soybean—cleaning—stones removal—magnetic selection—crushing—softening—flaking—drying—to extraction workshop.

1.Use cleaning screen, stoner and magnetic selector to remove kinds of impurities.

2.Use crusher to crush soybeans into small pieces.

3.Use softening pot to soften soybeans to increase their plasticity.

4.Use flaking roll to roll soybeans into thin flakes to incrase the surface area,convenient for extraction.

5.Use plate dryer to adjust the temperature and moisture of soybean flakes suitable for extraction.

Oil Extraction Process

1. Use rotocel extractor or loop extractor to extract oil with solvent to get miscella of solvent and oil.

2. Through twice evaporation and steam-stripping to separate solvent from oil and then get crude soybean oil according to their different boiling and volatility with evaporator and steam-stripping tower.

3. After extraction, wet meal with solvent will be desolventized to separate solvent,then dry meal can be used for feed.

4. Solvent from evaporation,steam-stripping and desolventizing can be recycled through condensation.

5.Exhaust gas can be recycled.

Soybean Oil Refining

Crude soybean oil—degumming,water washing,drying—decolorization—deacidification—deodorization—finished soybean oil.
