Modelling by finite element method of the twin-screw of a press for obtaining grape seed oil

Abstract

This paper is about getting grape seed oil using a twin-screw press. Grape seed oil is a by-product of the wine industry due to the need to reduce the amount of waste, but at the same time it has been found that this oil is an excellent ingredient that can be used in many industries. It is assumed that the use of twin-screw is more efficient than single-screw extraction due to the larger pressures that are created inside the press chamber. This study focuses on the finite element method analysis of how the press process is carried out. Using the finite element method, we can get an overview of how the pressure acts on the sides of the twin-screw, how it influences the temperature but also other process factors. When we have all these, we can begin optimizing the twin-screw press process.
