When operating the oil press machine, after a good deal of oil squeezed from the hopper into the breech. By pressing the spiral turn make the material to keep the embryos in advance, be pressed. Because of the embryo in the press material breech is squeezed state in the campaign, in virgin bore pressure conditions, resulting in a lot of friction between the material and the pressing screw embryo, embryo and virgin material breech, so make the friction, causing relative movement between the parison micro material. On the other hand, due to the pressing screw root diameter is gradually thickening Park pitch is gradually reduced, so that when pressing screw rotates, the thread hard material that is able to move forward embryo, but also outward and upward while pressing close to screw thread material layer surface with the pressing axis also rotates. Thus within each parison pressing bore particle velocity is not the same direction of movement, but also exist between the particles relative motion. The heat generated by friction and the oil extraction machine process operation satisfies the necessary heat, help to promote parison thermal denaturation of proteins, destruction of the colloid, an increase of the plastic, but also reduces some of the viscous oil to easily precipitate, thus improved oil yield press, so there is feed oil squeezed out, and row out of the gap and the gap from the garden bar row.oil press machine refers to the press by the action of mechanical force, by raising the temperature, activate the oil molecules will squeeze oil from the oil crops in the oil expeller machine.small scale oil extraction machine materials, oil-bearing crops is divided plant and animal raw materials, oil expeller machine production process, in general, mainly plant-based raw materials.oil press machine divided into screw expeller machine and hydraulic press machine,now introduces screw press.
Features of oil press machine
1. The automatic screw oil press is composed of vacuum filtration system, automatic heating device and controlling system.
2. Some parts of the oil press will be pre-heated before pressing, such as the press chamber, press screw and press ring.
3. During pressing, the press will filter the oil in due time.
4. This machine is matched with one controlling cabinet box to control all working process of the machines.
