It is widely used in the processing of rapeseed, cottonseed, soybean, peanut, sesame, tea seed, sunflower, olive, coconut, palm.

  High Quality Screw Oil Press

Introduction:

When oil presses operating prepared material enters extruding chamber from the hopper and then moves forwards by the rotating pressing screw and is pressed.

Under the high-pressure condition in the chamber, friction between material and screw, between material and chamber will be created, which also creates friction and relative movement among material particles.

On the other hand, root diameter of the pressing screw caries larger from one end to the other, hence. When rotating ,it not only pushes particles moving forwards but turns them outwards as well ,meanwhile ,particles adjacent the screw will rotation along with screw’ rotating ,causing every particle inside the chamber to possess different speed.

Therefore relative movement among particle creates heat which is necessary during manufacturing because of helping protein change property, damage colloid, increase plasticity, decrease oil’s elasticity, resulting in high oil productivity.

Operation:

Feeding must be steady and slow at the beginning to avoid blocking

In the case no cake is extrude outward,return back the screw for 1-2circle. If there is still no cake is observed,machine needs to be shut down and checked. However, in any case, operating the machine backward is absolutely prohibited normally, cake looks like tile but not sticky. Thickness is 1-2mm, inner side is smooth, outside creases and no oil the surface is allowed.

Cake thickness adjustment: Rotating the adjusting handle clockwise make the cake thicker otherwise will make it thinner. Each circle of adjustment (by adjustment bolt left hand T 165x6) will change the thickness 0.4-0.5mm.

When machine is operating, oil extruding and residue outlet need be checked

Normally, most of oil will flow outward from square rods and several front round plates.

 

Broken cake residue indicates the material is too dry steam emerging from the cake residue indicates that it is too wet. In any case, water content in the raw material must be adjusted from time to time.

Slag slice emerging indicates too much water content and power-like slag low water content .Loose round plates will cause too much slag flowing outwards.

However, adequate water content will cause slag flowing outwards from square rods. Little slag from round plates is allowed. In a word, water content affects oil output rate, it needs adjusting properly.
