Abstract

The main aims of this paper design and stress analysis of screw press oil expeller. There are several processes to extract oil from these e.g. chemical, centrifuge and mechanical. A mechanical oil expeller press was designed and analyzed with simulation software (ANSYS) in this paper. This expeller can be used in small scale oil extraction. ASME shaft design code was used in designing the screw shaft of the press. Locally available material (mild steel) was used in manufacturing of the expeller. A 20 hp, 3-phase electric motor was used for running the machine and the rpm of the screw was maintained 140 rpm. A screw rotates inside the barrel of the press which creates pressure for the extraction of oil. Raw material is feeded through hopper and compressed inside the barrel for oil extraction and the cake is discharged through a choke mechanism outside. The pressure on screw was determined and applied in the created meshed design with ANSYS software. From the achieved stress analysis it can be concluded that the screw used in this project is within safety limit of stress.
