YZ390 screw-type press

13406292820/13863706639 This year the company closed the sale of second-hand press, used chemical equipment, used pharmaceutical equipment. When the press operation, the treated good extra virgin oil from the hopper into the chamber. By the pressing screw turn make the material to keep the embryos in advance, be pressed. Since the parison in the press of virgin bore is in the state of motion, pressing bore under high pressure conditions, resulting in a great deal of friction between the material and the pressing screw embryos, embryos and virgin material breech, so make friction, resulting in relative movement between the micro parison material. Zhengzhou penguin 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 parison that is able to move forward, but also outward and upward while pressing close screw threaded surface of the material layer also with the pressing axis. Such virgin bore in each parison particle velocity is not the same direction, but there are also between the particles relative motion. Heat generated by the friction but also to meet the oil extraction process operation necessary heat to help promote parison thermal denaturation of proteins, destroys the colloid, increased plasticity, but also reduces the viscosity of the oil is likely to precipitate an oil come, thus improve the oil yield press, so that the oil in the oil squeezed out, and discharge gap and flows out from the circle shall discharge slit.
