Oil extraction machine
    Oil extraction machine is the production line of oil extraction equipment.
    Oil extraction is also called "extraction", which is a process of extracting oil and fat from oil with organic solvents. The leaching of oil can be regarded as solid-liquid extraction. It is a process in which the relevant components of solid materials are separated by the use of solvents with different solubility properties for different substances.
    During leaching, the oil is treated with a solvent, and easily soluble components (mainly oils and fats) are dissolved in the solvent. When oil leaching is performed under static conditions, the oil is transferred in the form of molecules, which is "molecular diffusion". However, the leaching process is mostly performed under the condition of relative motion between the solvent and the pellets.
    Therefore, in addition to molecular diffusion, it also has a "convection diffusion" process that depends on the flow of the solvent.
