Soybean oil mill plant
Henan Doing soybean oil mill plant adopts the most scientific cooking oil extracting method to extract crude soybean oil from soybean seeds. Usually, the whole set of soybean oil mill plant includes soybean oil pretreatment machine, soybean oil solvent extraction machine and soybean oil refinery plant.
Next we will introduce the whole process of extracting soybean oil from soybean seeds:
Complete set of soybean oil processing machine
Soybean oil introduction:
Soybean is one of the most important oilseeds all over the world. Soybean is distributed mainly over America(32%), Brazil(28%), Argentina(21%), China(7%),India(4%), Paraguay (3%), Canada(1%) and other countries.
Approximately 85% of the world's soybean crop is processed into soybean meal and soybean oil, the remainder processed in other ways or eaten whole. The soybean oil content is about 18%. Soybean is a kind of low oil content oilseed compared with other oilseeds as, peanut, sesame, canoal,etc. So usually we adopts soybean oil pretreatment and solvent extraction way to process soybean to get soybean oil. Compared with pressing way, pretreatment and solvent extraction way can reduce residue oil rate and increase oil productivity.
Soybean oil processing machine can help us get crude soybean oil and refined soybean oil from soybean seeds
Soybean oil mill process introduction:
About soybean oil mill plant, the process from soybean to first-grade soybean oil has three workshops, they are pretreatment workshop, solvent extraction workshop and refinery workshop.
Soybean oil pretreatment process of soybean oil mill plant:
Soybean→cleaning→remove stones→magnetic selection→crushing→softening→flaking→drying→to solvent extraction workshop
Soybean oil pretreatment and pre-pressing machine is one of the major equipment in soybean oil mill plant
Soybean oil pretreatment process is the basic process of soybean oil mill plant, is mainly to remove impurities in soybean, regulate moisture and temperature of soybean, and break soybean into small particles to change soybean molecular structure, etc, which is good for the following soybean oil production process.

After soybean oil pretreatment and pre-pressing process, we can get crude soybean oil and pressed soybean cake. Soybean cake willl be sent to the solvent extraction workshop to extract soybean oil or be used for extracting protein.
Soybean oil solvent extraction process flowchart:
Soybean cake→Solvent exraction system→D.T.D.C system→Condenser system → Recovery sysytem→Crude soybean oil
Soybean oil solvent extraction plant mainly used to extract soybean oil out from pressed soybean oil cake
The soybean oil solvent extraction plant is one of the most important equipment in the soybean oil mill plant. Soybean oil solvent extraction plant adopts the most scientific oil extracting method to extract crude soybean oil from soybean cake. With the help of solvent system, desolventizing system, condensing system and recycling system. We can get soybean crude soybean oil and soybean meal.(You may interested in: soybean oil solvent extraction plant)
Due to the crude soybean oil contains solid impurity, chemical impurity and smelly odour etc. So crude soybean oil need to be sent to the soybean oil refinery plant for further processing. Meanwhile, the soybean meal can be used as animal feed.
Quality indicators of crude soybean oil

Soybean oil refinery process flowchart:
Crude soybean oil-degumming--deacidifaction--decolorization--deodorization--refined soybean oil.
Soybean oil refining machine can be divided into three types, they are: batch type, semi-continuous and fully continuous
No matter after pressing or solvent extraction, the soybean oil you get is crude soybean oil. Only after refining can it be edible oil. Henan Doing Company's soybean oil refinery plant has three types according to different capacities and clients' requirements for final product oil.
After refining, we can get refined,bleached,deodorized oil. That is first-grade soybean oil. (You may interested in: soybean oil refinery plant)
