Solvent extraction is a process to extract the oil from oil bearing materials by means of a solvent. A typical solvent used is hexane, a by-product of petroleum. The solvent extraction plant machinery is designed to extract oil directly from oil seeds containing less than 20% oil, like soybeans, after flaking. Or it extracts oils from pre-pressed or fully pressed cake of seeds containing more than 20% oil like sunflowers, peanuts, cotton seed, palm kernels, canola, copra, castor and a variety of other materials. The purpose of solvent plant extraction machinery is to remove most of the oil contained in the seed. Extraction is conducted on prepared seeds or, as generally occurs in the case of high oil content seeds, the cake obtained from pre-pressing.
Cooking oil solvent extraction plant machinery
Cooking oil solvent extraction machinery steps:
1.Oil extraction
Main equipments in this station is oil extractor, there are many different types; oil extraction tanks, rotocel oil extractor ,loop type oil extractor, towline oil extractor etc.
2. Wet meal desolventizing and drying
After oil extractor, wet meal contains about 25-35% solvent. In order to recover this solvent and get high quality meal , using high temperature steam to evaporate solvent .
3. Mixed oil evaporation and stripping
After oil extractor, mixed oil contains solvent , which need evaporate . Evapotation is using different boiling point between oil and solvent to make solvent transform into gas evaporated.
4. Solvent condensing and cooling
Use condenser to make the cake cool and recovery solvent.

Edible oil solvent extraction process is a complex process. To design a reasonable technological process, we also consider the following factors:
Offer customized edible oil solvent extraction process solution according to different oil varieties (soybean, peanut, cottonseed, rapeseed, vegetable seeds…).
Ensure the edible oil solvent extraction process is adapted to the production capacity of your enterprise. Continuous edible oil solvent extraction process is suggested for production of large capacity, while batch type is more suitable for medium and small edible oil solvent extraction process .
Others, such as the reliability of the equipment and technology,labor productivity, theconsumptionrate of auxiliary materials, steam, water and electricity.
