Design and Development of an Efficient Screw Press Expeller
Experimental validation of the simulation is used to improve oil expeller for Jatropha seed by fabricating the expeller after the analysis of design by ANSYS FLUENT codes. An oil yield in excess of 98%, as compared to a maximum 75% for existing screw expellers, was achieved in practical runs which is very promising.
people living in tropical regions is Jatropha Curcas L; a plant that grows oil yielding seeds that contain 31-38% oil. The seeds need to be processed in order to obtain the useful end product oil. Mechanical screw pressing is the most popular method in the world to separate oil from vegetable oilseeds on small to medium scale.
DESIGN AND DEVELOPMENT OF SMALL SIZE OIL EXTRACTING ..., IJAER
Deli S et al.[4] carried out the research study effects ofphysical parameters in screw press machine. In this study Sativa seeds were studied using a KOMET Screw Oil Expeller. The study is carried out with different sizes of nozzle and at the different speed of shaft, also the different diameter of the shaft
A maximum oil recovery of 73.14% was obtained when Jatropha seeds were conditioned to a dry basis (db) moisture level of 9.69% and cooked at 110 degrees C for 10 min. Screw press oil recovery

D. Wiesenborn Rajeev Doddapaneni K. Tostenson N. Kangas. Agricultural and Food Sciences. 2001. Screw presses offer one means for extracting oil from crambe seed. Crambe seed was steam-cooked at 80 to 112°C for 5 to 20 min, dried to 6% (wet basis), and screw-pressed. Meal residual oil decreased….
The objectives of this CFD study are described as follows: (1) to determine whether the present design is able to develop the required pressure inside the barrel necessary for expelling the oil from Jatropha seeds; (2) to investigate the effect of screw rpm on pressures and yield of screw press expeller; (3) to estimate the frictional forces
Oil expression from Jatropha seeds using a screw press expeller
A maximum oil recovery of 73.14% was obtained when Jatropha seeds were conditioned to a dry basis (db) moisture level of 9.69% and cooked at 110 °C for 10 min. Screw press oil recovery, residual oil, pressing rate, and oil sediment content were measured at different moisture contents for uncooked and cooked seed.
This study focuses on the mechanical extraction of Jatropha curcas L. oil using a screw press type expeller. The extraction process was carried under different operating conditions to assess the impact on oil yield, oil recovery, extraction capacity, energy intensity, and the required properties as drop-in biofuel or as biodiesel feedstock.
Development and Performance Evaluation of an Optimized Screw
Screw oil expeller is a mechanical device which can generate pressure from rotation of feed to expeller screw manually or automatically. Screw press method for oil extraction is a mechanical method for extracting oil from raw materials. Extracted oil from screw pressing are used either as a food product or as an industrial product.
The Jatropha oil expelling machine has been designed to a capacity of 1000 kg/hr and can expel oil at the rate of 2.2 m3/hr. The machine is powered using electric motor of 40kW to be operated for
