Design and development of the oil expeller

The need for new designs of oil expeller is base on the cost and efficiency of the machine especially for the usage in small and medium size industries. It has to be cost effective and light weight to accommodate such demands. The existing oil expellers in the market are too big and too expensive for these small medium size businesses to invest on. Other limitations are its maintenances aspect as well as its operations. Therefore series of survey and interviews will be done to identify the needs and base on that the Final Design Specifications can be synthesize. The Oil Expeller functions like a screw type machine, which presses oil seeds through a barrel-like cavity. Raw materials enter one side of the press and waste products exit the other side. The machine uses friction and continuous pressure from the screw drives to move and compress the seed material. The oil seeps through small openings that do not allow seed fibre solids to pass through. Afterward, the pressed seeds are formed into a hardened cake, which is removed from the machine. This machine will satisfy the demand for the small and medium size industries because of its design, functionality and price. The measurements of the performance also being analyze by calculating the design efficiency. The resulting generalized model is validated through computer simulations and experimental ANNOVA.
