Henan Doing soybean oil mill plant adopts the most scientific oil extracting method to extract crude soybean oil from soybean seeds. The advanced designed production of soybean oil mill plant technology provides the high capacity soybean edible oil extraction with low investment.The whole set of soybean oil mill plant includes soybean oil pretreatment machine,soybean oil extraction machine and soybean oil refinery plant.
Next we will introduce the whole process of extracting soybean oil from soybean seeds:

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 pretreatment and solvent extraction way to process soybean and get soybean oil. Compared with pressing way, pretreatment and solvent extraction way can reduce residue oil rate and increase oil productivity.
Soybean oil is a vegetable oil extracted from the seeds of the soybean (Glycine max). It is one of the most widely consumed cooking oils. As a drying oil, processed soybean oil is also used as a base for printing inks (soy ink) and oil paints.

Soybean oil mill process:
About soybean oil mill plant, the process from soybean to first-grade soybean oil has three workshops, they are pretreatment worshop, solvent extraction workshop and refinery workshop.
 
Soybean oil pretreatment process of soybean oil mill plant:
Soybean---cleaning---stones removal---magnetic selection---crushing---softening---flaking---drying---to solvent extraction

Soybean pretreatment workshop 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 process in solvent extracton workshop. After pretreatment, we can get soybean cake. Soybean cake can go to the following solvent extraction workshop. Soybean  cake also can be used for extracting protein.

They are solvent system, desolventizing system, condensing system and recycling system. We can get soybean wet meal and crude soybean oil.
Soybean wet meal can be as animal feed, crude soybean oil contains solid impurity, chemical impurity and smelly odour etc. So crude soybean oil can go to next refinery workshop.

Quality indicators of crude soybean oil
 

Smell and flavour Smell and flavor , typical of soybean oil , without foreign smell
Colour Natural, brown with green tinge
Transparency slightly turbid, might have a small sediment
Mass fraction of fatless substances,%, not more than 0,20
Mass fraction of humidity, % 0,36
Acid value, mg КОN/g 4,00
Peroxide number,  ½ mol/kg, not more than 5,00
Mass fraction of substances which contain phosphates, %, not more than: 
in calculation to stearooleolecitine
4,00
Color quantity ( iodine value), not more than 100

Soybean oil refinery process of soybean oil mill plant:
Crude soybean oil-degumming--deacidifaction--decolorization--deodorization--refined soybean oil.
After refining, we can get refined,bleached,deodorized oil. That is, first-grade soybean oil.

There are different capacities available for the Soyabean Oil Mill Plant. We can provide and supply small scale as well as large scale soyabean oil plants. The common capacity is of 3TPD, 6TPD, 10TPD, 15TPD, 20TPD, 30TPD,50TPD,60TPD and so on.

The entire soyabean oil mill plant is designed, manufactured, supplied and started by us. The production and test run of the oil mill plant is also undertaken by our team of engineers and technicians. The client has to provide the space and building where the plant is to be installed. The whole Soyabean Oil Mill Plant will be based on turnkey project basis from start to end.
