Main equipment of peanut cake solvent extraction machine:

(1) Solvent pumps: continuously spray solvent to the rotary-type extractor;

(2)Rotocel 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: used 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.

Working principle of peanut cake solvent extraction machine:

a. The peanut cake (for pretreatment) is sent to rotary extraction by the scraper conveyor. The crude oil will extracted by the solvent or mix oil. After this step, we will get meal and mix oil

b. Meal is send to toaster. Through the toaster, the solvent in the meal will seperate from the meal. The solvent goes to condenser and is recycled to rotary extraction.

c. After the mix crude oil from the rotary extraction enters into 1st evaporator and 2nd evaporator, most of the solvent in the crude oil is separated.

d.The mix crude 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.
