ICMIEE-PI-160363 Design and Construction of Oil Expeller
From the achieved stress analysis it can be concluded that the screw used in this project is within safety limit of stress. The expeller has an efficiency & capacity ranging between 68.2% and 85
Here, the oil expeller is powered by human powered flywheel. II. POWER REQUIREMENT OF MACHINE The total power requirement of the machine is the sum of the power to drive the process unit ( PD) and power to extract the oil ( PE) , so = + Where, ( PD) = TD×ωD But, TD= WD×RD Where,WD = Weight of the pressing Screw=2.12×9.81=20.7972N;RD
Design and Development of an Efficient Screw Press
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
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

“DESIGN AND DEVELOPMENT OF A TWIN SCREW OIL
fabricated for a single screw oil expeller. The twin screw oil expeller was designed in detail using CATIA V5 and analyzed using ANSYS 14.5. Objectives: 1. To study the theory behind oil expelling process and analyze the practical problems associated with existing oil expeller. 2. To develop a concept design that can extract oil: i.
