Healthy Edible Oil Pretreatment Plant of Doing Group

Vegetable oil press production line includes two parts, one is pretreatmen

t line, and the other is oil seed press machine.Pretreatment part is used for cleaning and adjusting texture of the materi

als, it can improve oil yield rate, reducing breakdown of the machines. Genera

l speaking, the pretreatment machines include Magnetic drum, Cleaning sieve

s, Sheller, Crusher, Flaking roll, Cooker, Softening pot , Puffing machine and

so on. After pretreatment, the materials will be sent to oil expeller, then the cru

de oil got. Different materials have different pre-press methods. We usually co

llocate proper press line according to the customers' materials.Pretreatment production line is for cleaning and adjusting texture of the m

A. Magnetic drumA.Magnetic drum: It is making using of the magnetic power to remove the m

etal impurities, such as the iron nail and small steel, it can avoid these impuriti

es to destroy the machines in follow steps.

B. Cleaning sievesB.Cleaning sieves:

There is some mud, leaves and other pellets in oil seed; we need to use the cl

eaning sieve to remove them. The frequency movement can improve the effici

ency of cleaning, the light dust is removed by the suction system.Its processin

g capacity is large; it is usually adopted by the middle and large scale oil facto

ry.

s very little oil content in the shells, if we don't remove it, it will absorb away th

e oil from the kernel. It is usually used for processing peanut, sunflower seeds

, etc.

D. CrusherD.Crusher: It is used for crush the big size kernel to several pieces by extern

al power. About the soybean, peanut kernel, before prepressing, the crushing

E. Flaking rollE.Flaking roll:It is the process of making use of the mechanical action to flak

e the kernel into flakiness. After flaking, the materials is becoming thiner thank

before, it is good for absorb moisture and heat in cooking process , and it is

much easier for getting oil in the oil press process.

F. CookerF.Cooker: The main function of this part is wetting, heating, cooking and dryin

g the the flakiness, the effectiveness of the cooking will affect on the oil out rat

e and the quality of the meal.

G. Softening potG.Softening pot:It is usually used for processing the soybean. Its main functi

on is conditioning the moisture and temperature of materials, increasing its pla

sticity .This process also can be effectively preventing powder overmuch and r

oll banding in follow processes.

H. Bulking machineH. Bulking machine: It is usually used for processing rice bran in oil field. Th

e high temperature and pressure to make the materials into graininess. Duringthis process, the materials are puffing sharply, the internal moisture was evap

orated quickly and formed into loose structure, and

it is good for solvent extracting oil out.

I. Plate type dryerI. Plate type dryer: It is used for drying the moisture in the materials. After puf

fing, the moisture content is about 11%-13%, it is too high, and

it is not suitable for solvent extracting, so we need to dry moisture to 7%-9%.- See more at:
