Abstract

An expelling machine for extracting oil from wheat germ was designed and fabricated to be suitable for young investors. The procedures include the design stages, construction and testing. The main machine components are: Hopper (feeding inlet); expellant unit and an electric motor. The power is transmitted by means of a set of pulleys; sprockets; V-belt; chain and speed reducer (gear box). The expelling unit consists of two screw expellant shafts with two expellant barrels. The expeller evaluated at five screw speeds (25, 35, 45, 55, and 65 rpm) and four levels of press head clearance (0.5, 1, 1.5, and 2 mm) to determine the best Machine capacity (kgh-1); Specific energy consumption (kWhkg-1feed); Oil recovery (%); and Oil residual (%) in wheat germ cake. The results showed that, the maximum barrel temperature was 65.5°C which assured production of good quality wheat germ oil, deoiled cake. The better oil extraction efficiency was at the speed of 25 rpm, when press head clearance was 0.5 mm. The specific energy requirement was 0.042 kWhkg-1feed for the optimized pressing conditions.
