Brief introduction of solvent extraction plant 

1)The solvent extraction plant is part of vegetable oil processing plant which is designed to extract oil directly from oil seed containing less than 20% oil like soyabean fter flaking or it extracts oils from prepressed or fully pressed cake of seeds containing more than 20% oil like sunflower, peanuts, cotton seed, palm kernel, canola, copra, castor and variety of other materials.

2)This equipment suitable for soybean, cottonseed, rapeseed, corn embryo, rice bran and so on. For the low oil content oil materials, generally adopt extruding-extracting technology, which technology can destroy the oil cell structure, passivating the enzymes and this kind of poisonous element, make the flake extruding, enlarge the contact area with the solvent, favorable for the oil extraction.

3) For the high oil content oil materials, adopt pre-press and extraction technology. It can get some oil from pre-press procedure, then extractiong the oil cake after pressed, to enhance the efficiency of extraction

Method of solvent extraction 

There’re two refining technologies in oil refinery plant, one is batch, the other is continuous. Normally we adopt batch type when the capacity is less than 20MTPD, otherwise, we adopt semi-continuous or continuous technology.

The latest refining equipment consists of many single units and has the heating system itself which save energy without using boiler. This equipment occupies less area and funds, furthermore, it has more functions and can be used to produce Grade 1, Grade 2, Grade 3 & Grade 4 Oil etc..It’s an ideal equipment for clients.

 Flow of solvent extraction 

The material(for pretreatment) is sent to the extractor by the airtight packing auger. The mateiral will be sprayed for extraction by the solvent(Hexance) or mixed oil after they fall into the extractor. The wet dreg(after dripping), falling into the conveyor and be sent to the evapo-separated machine. After steaming, baking and desolventizing, the dreg will be sent to the dreg storehouse. Mixed oil after extraction enters into the first and second long tube evaporator for seperating the steam and solvent, and then flow into the stripping tower for desorption the remaining solvent of crude oil. The extracted oil from the last process will be sent into the crude oil tank for refining plant. The solvent vapors from the extractor, evapo-separated machine, evaporator, stripper tower will be recycled in the cooling system. The solvent after cooling will be collected in the fresh solvent tank for reusing in the process.

Main equipment:

Rotocel extractor(loop type extractor), evapo-separated machine, Long tube evaporator, stripper tower, condenser, absorber, conveyor, sealing auger and so on.
