The oil press expels oil by the application of pressure to seeds inside a cylinder and cage by means of a piston and a system of levers. Under the pressure built in the cage the seeds release oil. To operate the machine a handle is used to press the seeds. One requirement of operation of the oil press is that the oil pressing process should be continuous from the beginning to end. The machine is designed to be portable and to be repaired locally. Specifications: -Mass: ~40 kg -Piston diameter: 30 mm -Handle length: 1 m -Bushing: none -Cage shape: straight
The user needs to lubricate parts like the bolts and nuts weekly. Also, they should be retightened and cleaned twice a week.
Manufacturer Specified Performance Parameters
It is designed to be operated by one man with a stroke rate of 12 to 20 strokes per minute
Vetted Performance Status
The press' extraction efficiency has been vetted by scientists at Kebbi State University of Science & Technology, Nigeria
