Description
Summary:The extraction of oil from oilseed material by mechanical pressing is carried out in special machines called mechanical presses. The press's primary component sections are the transmission, press bearings, feed area, press chamber, screw, and barrel output. The screw plays a crucial role in a press's operation. A rotating helical body (screw) inside a cylinder-shaped enclosed space produces the pressing force (pressing chamber) in mechanical presses. In this article, we have designed the screw of an oil press to obtain oil from grape seeds. To make the 3D model, we used SolidWorks software, after which we also simulated the model under stress conditions. In the first phase, the behavior of the 3D model will be simulated for the screw with which a small press is equipped, a model most often used in farms for obtaining oil. Later we also simulated a screw model with a larger pitch to observe the differences in behavior between them. In this paper, we show whether the different pitch of the screw press models influences their degree of erosion and fatigue.
