Press; it is designed to produce oil and cake, by extracting oil by pressing oil seeds in the worms of the press after they are conditioned at cooker. According to the entry conditions of the next extraction unit, required amount of oil is left in cake. The construction of the press has a very important role in ensuring accuracy of the oil amount to remain in cake and the capacity. Design, material and life time of the cage bars, scraper bars and worms is very critical. Also, the motor, belt-drum, reducer, press main shaft, bearings and the body, where the pressing power is transmitted, have been developed to meet the demand in the best manner using the most advanced technology and engineering. The importance of research-development is ever increasing in today’s economy, where competition at the highest level is being experienced. Firms are could only survive by attaining and using the technological developments in the shortest time.
