(1)Pump crude oil into refining tank and heat with conduction oil, and the temperature will reach about 70°C-80°C after one hour. Add acid or alkali to separate according to the acid value. After one hour's processing and 4-6 hours deposit, then convey soap stock to storage tank.
(2) Pump refined oil into decoloring tank. When it is up to 90-110 °c after one hour's heating, add clay into tank for 20 mins' processing.Then clay and oil are separate by filter.
(3)Put discolored oil into deodorization tank with vacuum pump. Heat and process with steam for odor removal. After filtering, you will get final oil product. Technical Description: Oil solvent extraction plant 1.The complete extraction equipment is applicable to extract oil from the adopt expanding and extracting technical.
2.Pre-dealing expanding technical break the oil cell structure, passivate the enzyme in the oil-cake/flake. Squeezing and expanding to the mould make the contacted area bigger with solvent, so as to make for extraction from expanding materials (cake, embryo).
3.The extraction technical generally extract oil from cake and embryo by pre- extraction or direct extraction.
4.The whole equipment is composed of solvent extracting, wet meal roast & desolventing machine, long pipe evaporator, discal stripper, condenser and other equipment, and it’s matched with explosion proof motor, various kinds of connected pipes in plant, as well as the required accessories of instrument, apparatus, valve and so on.
