Double Chamber Oil Expeller with Long Steam Kettle

An oil expeller machine is a mechanical device that is used to extract oil from seeds and nuts. It presses the seeds or Nuts to squeeze out the oil, separating it from the solid residue. This process is called oil Pressing or oil extraction, Here's how an oil expeller machine generally works:

Feeding: Seeds or nuts are fed into the expeller's hopper.

Pressing: Inside the machine, there is a horizontal shaft with pressing worms or screws. These screws apply pressure to the seeds, causing oil to be squeezed out. The design of the pressing chamber varies based on the type of oilseed being processed.

Oil and Residue Separation: The expelled oil is then collected through small openings on the barrel of the expeller, while the solid residue (also known as cake or meal) is ejected from the other end.

Filtration: The extracted oil often contains impurities and needs to be filtered to make it pure and ready for consumption or further processing.

Oil expeller machines are commonly used in small and medium-scale oil production plants. They are widely used for extracting oil from various oilseeds such as sunflower seeds, soybeans, peanuts, cottonseeds, palm kernels, and sesame seeds, among others.

Different types of oil expeller machines are available, Fanging from manual to automatic models, Catering to various production capacities. The choice of an oil expeller machine depends on the scale of production, the type of oilseed, and the desired output.
