11.7/8 Inch Cage Bar Oil Expeller

A cage bar oil expeller, also known as a screw press or oil press, is a mechanical device used to extract oil from various oil-bearing seeds or nuts such as soybeans, peanuts, sunflower seeds, rapeseeds, and more. It operates on the principle of mechanical pressure applied to the seeds or nuts to extract the oil.

Here is a basic description of the parts and functions of a cage bar oil expeller:

1. Cage or Barrel: The main component of the oil expeller is a cylindrical cage or barrel where the seeds or nuts are fed into.
2. Screw Press Mechanism: Inside the cage, there is a screw or worm shaft that rotates and exerts pressure on the seeds/nuts. The rotation of the screw crushes the seeds/nuts and forces the oil out through the openings or small gaps in the cage.
3. Cage Bars: The cage is lined with cage bars or bars with small gaps between them. These bars allow the expelled oil to flow out while retaining the solids or pressed cake inside.
4. Pressure Adjustment: The pressure applied by the screw can often be adjusted to suit different types of seeds or nuts and achieve optimal oil extraction.
5. Feeding Mechanism: Seeds or nuts are fed into the expeller through a hopper or feeding mechanism, which is usually located at the top of the machine.
6. Oil and Cake Separation: As the oil is pressed out, it flows through the gaps in the cage bars and is collected, while the remaining solid material, known as the pressed cake, is expelled from the other end.
7. Oil Collection: Extracted oil is collected in a container or through a channel designed for oil collection.
8. Motor or Power Source: Oil expellers are powered by electric motors, diesel engines, or other sources of mechanical power to drive the screw mechanism.

Cage bar oil expellers vary in size and capacity, from small-scale manually operated machines to large industrial-scale units capable of processing significant quantities of seeds or nuts to extract oil.

These machines are widely used in the agricultural and food processing industries for producing edible oils, as well as in other industries for extracting oils used in cosmetics, pharmaceuticals, and various industrial applications.
