What’s Solvent Extraction?

Solvent Extraction, as the title suggests is a course of to extract oil from oil bearing materials via a solvent. Generally, Hexane (a petroleum by-product) is used because the solvent.

What are Solvent Extraction Plants?

Solvent Extraction Plants are used to extract oil by using chemicals. These plants use cake as the uncooked materials, which is obtained from the oil press part. An organic solvent is used to dissolve the cakes or seeds oil content material after the process of dipping or spraying, which ensures that the oil content material is in shut contact with the feeding materials. After this, the solvent is vaporized out and the oil is collected. In these plants, the vaporized solvent is recycled.


There are numerous Solvent Extraction Plants manufacturers, who use the quality assured materials and newest expertise within the fabrication process. Typically, these plants are designed especially for extracting oil directly from oilseeds that comprise less than 20% oil resembling Soybean after the process of flaking. Pre-pressed or totally pressed seed cake that comprise over 20% oil equivalent to cotton seed, palm kernel, sunflower, copra, Castor, peanuts, and others.

A lot of the edible oil manufacturers now-a-days use the horizontal extractors that operate on the principle of counter present, transferring mattress. It has varying top of bed and various speed mechanism that allows absolute extraction by good penetration & percolation of the solvent.

Procedures followed in the solvent extraction process:

Dip oil-wealthy flake or pre-pressed cake into solvent
Dissolve vegetable oil into chemical solvent
Filter stable material
Evaporate oil mixed solvent to separate oil and solvent
Cool and recycle solvent
Further process oil and cake.

One of the best attribute of the solvent extraction plant is that it provides easy change-over of the process materials. These plants also find utilization in the extraction of assorted useful solvents in assorted industries.

Salient options of the standard solvent extraction plants:

Obtainable in solid 聳 liquid and liquid 聳 liquid extraction techniques
Uses various solvents polar or non polar or a mixture of both
Versatility to process all kinds of seeds, bran or oil cakes
