Peanuts Solvent Extraction Plant

Peanut oil (arachis oil) is an organic material oil that derived from peanuts, noted to have the aroma and taste of its parent legume. Peanuts / Groundnut oils can be extracted in various ways. Always  method used depends on the oil.

Peanuts / Groundnut oils are often extracted using a solvent like hexane, while aromatic oils are extracted with various methods including steam distillation and the traditional cold pressing method. In all of these options, the goal of extraction is to produce a pure oil free from contaminants and traces of the original plant material.

Peanuts / Groundnuts Solvent Extraction Plant Process

Solvent Extraction is a process which involves extracting oil from oil-bearing materials by treating it with a low boiler solvent as opposed to extracting the oils by mechanical pressing methods, such as expellers, hydraulic presses, etc. The solvent extraction method recovers almost all the oils and leaves behind only 0.5% to 0.7% residual oil in the raw material, such as peanuts solvent extraction plant or ground nuts solvent extraction plant etc. In the case of mechanical pressing the residual oil left in the oil cake may be anywhere from 6% to 14%.

Peanuts / Groundnuts are first decorticated to remove the husk. The kernels so obtained have an oil content in excess of 48%. The kernels are subjected to mechanical extraction with the help of screw presses. The resultant cake has residual oil content varying from 8 to 12% depending on the extent of pressing. The pre-pressed cake is subjected to solvent extraction process for recovery of the residual oil.
