Introduction of oil extraction equipment :
Solvent condensation system combines with evaporation system closely, and evaporative condenser and steam stripping condenser all work under negative pressure.
Non-condensable gas enters the energy saver from the shell of the first evaporator. In energy saver, noncondensable gas exchanges heat with condensate from the evaporative condenser.
Finally, the condensate temperature discharged from energy saver is increased, and the solvent separated water from going to the solvent holding tank.
The high temperature makes it unnecessary to be reheated for the recycling, so as to save energy. Noncondensable gas from energy saver enters desolventizing condenser, in which a great deal of gas is condensed, and the tail gas is discharged into the final condenser.
Flowchart of oil extraction machine:
Oil seeds → cleaning → softening → flaking → extrusion → drying → to extraction workshop →DTDC →first and second evaporation →stripping tower →condenser →solvent recovery

Advantage of oil extraction machine:
1) The material (for pretreatment) is sent to rotary extraction by the scraper conveyor. The material will extracted by the solvent or mix oil. After this step, we will get meal and mix oil.
2) Meal is send to toaster. Through the toaster, the solvent in the meal will separate from the meal. The solvent goes to condenser and is recycled to rotary extraction.
3) After the mix oil from the rotary extraction enters into 1st evaporator and 2nd evaporator, most of the solvent in the mix oil is separated.
4) The mix oil from 2nd evaporator goes to stripping tower and almost all the solvent is separated. From the stripping tower, we can get crude oil and solvent. The solvent is sent to condenser and is recycled to rotary extraction.
Process of pretreatment
Cleaning device:remove the raw material peanut in various impurities, such as: iron, stones, clump, such as the plant leaf, clean up till impurity content does not exceed 0.2%.
Crushing machine: peanut is crushed into 6-8 pieces. In order to meet the requirements of crushing, the peanut is suitable for crushing with the moisture of 7% to 12%.
Softening process:the purpose of softening is to adjust the moisture and temperature of oil, and make it soft.
Flaking process: rolling raw material into flakes, and the purpose is to increae surface area, destroy the peanut cell tissue, shorten the way of oil out from cake.
Extrusion:through high temperature and high pressure, soybean flakes are transfered into expanded pellet, which is easy to extract oil from, and keep high nutritive value.
Process of oil extraction machine:
(1) Solvent pumps: continuously spray solvent to the rotary-type extractor
(2) .Roary extractor: Spray and soak the pre-pressed cake with solvent so that oil fats can be dissolved in solvent(form miscella). After processing, you can get wet meal and miscella (mied oil).
(3) DTDC: usd to separate the solvent from the wet meal.
(4) Miscella tank 1st: pump the miscella (oil with solvent) in to the miscella 1st , and then add 10% saline water to it. The phospholipid and impurities in the miscella will react with the saline wter, at last the reactant precipitate, reaching the goal of purifying.
(5) Miscella tank 2nd: the purified miscella will be pumped into it.
(6) stripping: it will remove the remaining solvent in miscella. And the solvent will be discharged to condenser for recycling.
(7) condensers: used to cooling the solvent gas separated from the wet meal and miscella for recycling.
