Feed Material: The raw material (like crushed seeds or nuts) is fed into the press. This material usually contains a mixture of oil and solid particles.
Pressing: The feed material is subjected to high pressure within the press. This pressure forces the oil out of the material and into a separate chamber, while the solid particles are retained.
Filtration: The oil that emerges from the pressing stage is often still mixed with some small solid particles. The filter press includes a series of filters or filter plates that help to further separate these particles from the oil.
Collection: The filtered oil is collected in a container for further processing or storage. The solid residues, also known as oil cakes or press cakes, are typically removed from the press and can be used for animal feed, fertilizers, or other purposes.
Oil filter presses are used in various applications, including:
