4.0 Process Description of Soybean Oil Pressing Workshop
4.1 Soybean Oil Pressing Process Diagram                                                   
Soybean → cleaning,stones removal → crushing → softening→ flaking→ cooking→ oil pressing→ 
crude soybean oil → filtration                 
4.2 Process Description (Pictures only for reference,goods in kind prevail)   
4.2.1 Cleaning and stones removal
Utilize different particle size,adopt high efficiency vibration cleaning sieve to remove big and small impurities from soybean, then utilize the different suspension velocity between stones and soybeans and use specific gravity stoner to separate heavy stones from soybeans, with good cleaning and selection effect.Adopt magnetic selector to separate magnetic metal impurities from soybeans.


Crushing machine
Tooth roller crushing machine is comprised of one pair of husking roller with tooth socket, when materials enter the space between tooth and roller through feeding roller, due to the combined action of velocity difference and constant pressure on two rollers, make soybeans suffer shear and extrusion, and divided into 6-8 pieces, this machine adopts high strength alloy steel roller, with features of long working life, good wear-proof effect, convenient maintenance, cheap accessories.


 Cooking
Adopt layer steam cooker,the maximum distance between stirring wings on each layer and the bottom of steam cooker is 5mm,avoid stirring unequally,complete steam cooker is sealed, to keep the space upper flakes have maximum moisture,make flakes be steamed and uniform.  

Oil Pressing
Adopt matured special soybean oil pressing machine, residual oil in pressing cake is low, the most important feature is once pressing,the quality of pressing cake is good, low energy consumption, small covering area.

 Filtration
Adopt oil clarification tank with function of automatic discharging oil residue,avoid manual cleaning screen clothes, working efficiency is high, filtered oil residue goes back for pressing automatically,this section also configurates clarification slag salvaging machine, make sure the least oil residue in crude oil,and ensure later degumming section effect.

 Conveying equipment
We configurate conveying equipment with advantages of stable operation and good sealing effect,  adopt famous brand motors and reducers.

2.3 Water consumption:     ≤ 0.2t/t (soybean oil) 
3.0 Soybean Oil Refining Process Description
3.1 Oil Refining Process Diagram
                  phosphoric acid  hot water                           bleaching clay
                            ↓      ↓                                      ↓ 
Crude soybean oil → fitration → degumming → deacidification  → vacuum drying → bleaching → deodorization → refined soybean oil.
4.0 Process Description
4.1 Degumming,alkali refining and water washing section
Adopt batch type refining technology, add phosphoric acid to make nonhydratable phospholipids transform into hydratable phospholipids, at the same time, complex plenty of iron ions dissolving in oil in the high FFA production process,add caustic soda lye to make it neutralize free fatty acid to generate soap-stock and absorb impurities in oil,add hot water for water washing,discharge and recycle soap-stock,then temporarily store soap-stock in soap-stock tank.
Vacuum dehydration and adsorption bleaching section
Combine vacuum dehydration and adsorption bleaching into one decolorization tank, heating medium is steam or heat conduction oil,under vacuum condition, finish dehydration and bleaching, decrease the temperature, and pump it into vibration filter to separate waste bleaching clay from clear oil.
4.3 Vacuum deodorization section
Adopt stainless steel equipment, use heat conduction oil as heating medium, increase the  temperature to 240-260C so that under required high temperature and vacuum condition, remove free fatty acid and off-flavor.
