If the virgin material virgin material internal friction and particle-particle friction and squeezed between the outer surface of the shaft between the particles and the friction material than virgin pressed cage between the surface, then the virgin material generated with the shaft rotation. When screw press work, pressing material rotates with the shaft movement is not normally allowed. In pressing cage surface resistance virgin material particles and larger surface pressed cage with the axis of rotation to offset the week to force, but in the middle layer, pressed material particles depends mainly on the role of the internal friction of Henan oil press manufacturers, its resistance small, especially in the feed section, the friction between loose particles virgin material is smaller, then it is easy to produce the phenomenon of virgin material rotating with the shaft. In addition, the friction of virgin and extra virgin material between the shaft surface is also prone to rotating with the shaft. Thus, each radial layer of virgin material with the rotation of the shaft is inconsistent. In order to prevent the phenomenon of virgin material with the shaft in the screw press means pressing a blade bore Henan peanut oil press, press and shaft surface finish, and when pressed to make juice bar cage surface means having " spine sex. " Screw press screw shaft is the most important part. Working screw shaft continuously push forward when the pressing material and its press. Due to strong compression screw shaft friction virgin material, so it is easy to wear. Promising structure type screw shaft integral, shaft-mounted, variable speed screw shaft three. Outfitted with a screw shaft is a whole shaft drive from the system, pressing shaft wear to a certain extent the need to replace the entire shaft, very economical, only for a small press. The vast majority of press using shaft-mounted helical axis, is about a steadily pressing bolts (or pressing bolts and pitch circle) in order to rotate the shaft suit assembled into the screw shaft. Set screw shaft pressing screw according to a continuous spiral or not, is divided into two kinds of intermittent and continuous spiral configuration from the ring. The former is characterized by a short press time, pressing bore pressure, low back material, suitable for cold pressing and squeezing the whole seed. As ZX10-type screw press which uses a continuous suite of the screw shaft. The latter is characterized by the use of distance ring and pressed the blade bore with Henan press equipment, make virgin material were turning in the pressing chamber, avoiding virgin materials with the shaft and blocking passage of negative phenomena, while relatively extended the press time, help to improve the oil effect. Henan peanut oil press, Goodwin machinery (certified), press provided by Nanyang City, Qi Feng Machinery Co., Ltd. Nanyang City, Qi Feng Machinery Co., Ltd.
