Soybean oil is a very import edible oil for human beings. In extraction plant/mill, crude soybean oil can be extracted out after effect of pre-treatment. Please feel free to contact us for more information.Extraction plant is refer to get the crude oil from flake produced by the pretreatment & prepress plant with normal hexane extraction process. Production processes include Oil Extraction.Wet Meal Desolventization,Mixed oil Evaporation and Stripping, Vent Gas Recovery

1. Oil Extraction

The method of extracting oil is a kind of oil extraction method, based on the principle of extraction, which can make the solvent contact with the pretreated oil， then dissolve the oil and grease of the solvent. 

v The Advantages of Extraction Technology are as follows:

1. The oil production efficiency is high; the residue oil rate in meal is less than 1%, and the high quality of meal is conducive to the comprehensive utilization of meal.

2. Easy to achieve mass production and production automation.

3. The whole production line takes closed processing with low operating temperature,and good production environment.

4. Suitable for all kinds of oil plants extraction.

2.Wet Meal Desolventization

The discharged meal contains 25% to 35% solvent , in order to recover the solvent and obtain better quality meal, the meal can be heated to evaporate the solvent .

Unique design of steam-permeability tray ensures thorough contact between wet meal and steam, which can help to reduce direct steam consumption and achieve good desolventizing effect. Outlet temperature of secondary steam is low.

3. Mixed oil Evaporation and Stripping

Mixed oil evaporation and steaming (Mixed oil filtration, mixed oil tank, the first evaporator, the second evaporator , stripper and extracted crude oil)

4. Vent Gas Recovery

The air contains a lot of solvent vapor . Before discharging, the solvent is required to be recovered.

Part of solvent of condensate can be recovered, but there is still some immature gas, containing a small amount of solvent, which should be recycled before discharging the waste gas.

Advanced designing, modern technology, high quality equipment, excellent installing and commissioning, round after-sales and long time service.

As a national famous company in this field, we are ready to help you in edible soybean oil engineering projects from the very beginning to the last point.
