what is the oil extraction machine

     



Oil extraction machines come in various types and designs depending on the specific application and scale of production. Here are some commonly used oil extraction machines:

  1. Screw Press or hot press Oil Expeller: This is one of the most common types of oil extraction machines. It uses a screw-shaped device to compress and extract oil from seeds or nuts. The seeds are fed into a cylindrical hot chamber where they are crushed and pressed, causing the oil to be released. Normally this method is used for bulk oil production by using steam to create a hot temperature inside the chamber.


  3. Solvent Extraction Machine: This method is typically used for extracting oil from oilseeds with low oil content, such as soybeans or rapeseeds. The seeds are first ground and then treated with a solvent, such as hexane, to dissolve the oil. The solvent-oil mixture is then separated, and the solvent is evaporated to obtain the oil.


  5. Hydraulic Press: Hydraulic presses use hydraulic pressure to extract oil from seeds or nuts. The seeds are placed in a press and subjected to high-pressure conditions, which squeeze out the oil. Hydraulic presses can be manual or powered by electricity or hydraulics. nowadays, this method is very rarely in use.


  7. Cold Press, marachekku, chekku machine or Rotary Press: This method is familiar in Ancient India, Rotating the crushing chamber slowly to crush and press the oil seeds, but it operates at very lower temperatures to retain the natural qualities of the oil. Cold pressing avoids the use of heat or chemicals during extraction and is often preferred for producing high-quality oils.


  9. Centrifugal Oil Extractor: This type of machine utilizes centrifugal force to separate oil from the solid particles in the seed or nut. The crushed material is fed into a rapidly spinning centrifuge, where the oil is separated and collected.


  11. Supercritical CO2 Extraction: This advanced method uses carbon dioxide in a supercritical state to extract oil from various plant materials, including seeds. Supercritical CO2 acts as a solvent, dissolving the oil components, and then the CO2 is separated, leaving behind the oil.

These are the oil extraction machines commonly used. The choice of machine depends on factors such as the type of oilseed, desired oil quality, production scale, available resources, and budget. It's important to research and consult with manufacturers or industry experts in

Wood Press Oil Machine

Image
  Wood Press Oil Machine      A wood press oil machine or ghani oil extraction machine, also known as a traditional oil mill or kolhu, is a type of oil extraction equipment that has been used for centuries in India and other regions. It is commonly used to extract oil from seeds, such as sesame, mustard, groundnut (peanut), and coconut.      The Ghani machine consists of a large mortar made of stone or wood, known as a "kohlu" or "Ghani." The mortar means the base part of the crushing chamber is fixed in an upright position, and a heavy cylindrical pestle is attached to a central wood. The beam is connected to an animal-driven or manually operated system that provides the rotational force for crushing the seeds.      The oil extraction process involves placing the seeds in the mortar and continuously rotating the pestle to crush and grind the seeds. As the seeds are crushed, the oil is released, and it seeps out through small openings i...
