Solvent extraction plant is used for
extracting oil from seed or cake. For soya bean seed it is widely use in all
over the world, for that seed preparation and seed cleaning system is
requires.
- Oil cakes consists about 6 to 8% of oil that is received from oil
Mill and seeds are contains from 18% to 28% of the oil in the seeds
- For seeds cleaning and flaking is requires and cake is in big pieces
fo it requires to make in small pieces through cracker and barker as a
form of pieces in the sizes of 3mm to 5mm
- If there is seeds it passes through conditioning and flaking, for
cake feed it in pieces
- The prepared material then fed into Solvent Extraction Plant through
conveyor
Solvent Extraction has following stages :
- Rotary Valve and feeding chain
- Extraction of oil from seeds/cake in extractor
- Distillation/Evaporation of Hexane to recover Oil from miscella
- De solvent of Extracted Meal
- Condensation of Hexane and prepare for recycling
- Solvent absorption system
The solvent oil is not for human consumption so it will send to
refinery for refining of oil and removing of all impurities. The cake is
called de oiled cake then passes through cooling system and sends for
packaging
Features of Solvent Extraction plants :
- Because of Solvent requires fire hydrant and safety system
- Low flow resistance
- Very durable
- Cost effective
- require low maintenance but requires continue watch
