Soybean oil extraction machine

Energy consumption in process of 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

Loop type oil extraction

Soybean oil extraction process:
Flaked Material→Extraction → Wet meal →Desolventizer→Cooling →Dry meal packing
Mixed oil→Filter→Evaporation→Crude soybean oil
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.
