Soybean oil extraction is one time oil extraction, that is, soybean seeds goes directly to oil extraction after soybean pretreatment without pressing, because soybean oil contain is low. 

♦Material for soybean oil extraction :  flaked soybean , thickness about 0.3mm
♦Chemical used for soybean oil extraction:  Solvent N-hexane
♦Soybean oil extraction types:  batch soybean oil extraction(using extraction tanks for small capacity) or continuous soybean oil extraction(Rotocel oil extractor, looptype oil extractor or towline oil extractor etc)

1. Soybean oil extraction process

After pretreatment, flaked soybean will go to oil extractor to extract oil with solvent N-hexane . After oil extractor, we will get mixed oil and wet meal. Solvent will be evaporated from mixed oil through evaporators and cooled down inside condensers. And wet meal will be dried inside desolventizer and solvent is transforming into gas and evaporated. 

2.Energy consumption in soybean oil extraction plant (per ton of flaked soybean)

Electricity consumption:                               < 1.5kg/T
Solvent consumption:                                   < 1.5kg/T
Water consumption:                                      < 20kg/T (recycling)
Water contain in soybean meal:                      10.5~13% (adjustable)
Oil contain in soybean meal:                           < 0.8%
Solvent in soybean meal:                                <500PPM
Solvent in crude oil:                                       <200PPM
