Edible oil production line and soybean oil solvent extraction

Edible oil production line and soybean oil solvent extraction

Soybean oil solvent extraction Description
It is a modern and one of the most advanced oil extraction equipment that fixed grid of stainless steel plate extractor. Retained its low power consumption, reliable operation of equipment , long life ,easy maintenance, good benefits leaching effect compared with traditional false bottom and extractor. 

Daily treatment :  30T, 50T, 80T,100T,150T, 200T, 300T, 450T, 600T, 800T.  As your requirement

Soybean oil solvent extraction Production Process
(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 sent 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.

Soybean oil solvent extraction Main parts
(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 (mixed 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). Miscella 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.

Soybean oil solvent extraction Advantage
(1) Energy & labor saving; high oil yield rate ;
(2) 1.5% low residual oil rate of meal ; good quality meal
(3) Low solvent consumption, high solvent recovery
(4) Low processing cost , high labor productivity.
