Screw Oil expeller (oil press machine) make use of screw driving force to squeeze oil from plant seeds.This machine can be used to press all kinds of oil seeds for the edible oil such as peanut ,rape,beans,sesame,sunflower,cotton seeds,coconuts,cocoa and grass seeds.,etc. The press methods include hot press and cold press .The machine also have single screw oil press machine and combined oil press machine. The single machine need use other machine such as filter machine and roll frying pan etc. The combined oil press machine have include the heater and oil filters. When oil press is operating prepared material enters the 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 moying forwards but turns them outwards as well. Meanwhile, particles adjacent the screw will rotate along with screw's rotating, causing every particle inside the chamber to possess different speed . Therefore, relative movement among particles 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.please visit www.oilmillcn.com to learm more detailed information.
1.1 Preparation before operating
1.1.1 12 kg of lubricant needs to be filled into the gearbox.
1.1.2 After installing the machine, check whether lubricant has been filled in, bolts have been tightened, and handles are operable.
1.1.3 Check large pulley whether it is loose or blocked, repair it if necessary.
1.1.4 Adjust the tightness of the brlt. Switch on the motor and check its rotation direction.
1.1.5 Loosen the lock nut and tighten the screw to its end, then loosen it for 3-4 circles and then tighten it again for half circle to assure the gap of the residue cake outlet.

2.2.2 In the case no cake is extruded outward, return back the screw for 1-2 circles. If there is still no cake is observed, machine needs to be shut down and checked. However in any case, operating the machine backwards is absolutely prohidited. Normally, cake looks like tile but not sticky; thickness is 1-2 mm, inner side is smooth, outer side creases and no oil the surface is allowed.
Cake thickness adjustment: Rotating the adjusting handle clockwise will make the cake thicker, otherwise will make it thinner. Each circle of adjustment (by adjustment bolt left hand T 165×6）will change the thickness 0.4-0.5 mm.
2.2.3 When machine is operating, oil extruding and residue outlet need to be checked frequently. Normally, most of oil will flow outwards 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 powder-like slag low water content. Loose round plates will cause too much slag flowing outwards. However, adequate water content will not cause slag flowing outwards from square rods, yet, little slag from round plates is allowed. In a ward, water content affects oil output rate, it needs adjusting properly.
