(1) Function: Leaching system is an oil extraction through soaking or spraying pre-pressed cake by a certain organic solvent. The principle of this part is the different solubility of solvent.

(2) Use range: Solvent extraction fits for pre-press extraction of high-oil-content materials and direct once time extraction of low-oil-content materials.

2. 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 solve(form miscella). After processing, you can get wet meal and micella (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 water, 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.

Rotocel extractor:

1.Specially suitable for the extraction of various pre-pressed meals.

2.Adopt stainless steel fixed grid plate and increase the horizontal grid plates, which can prevent the strong miscella from flowing back to the blanking case, so as to ensure good extraction effect.

3.The feeding system can adjust the rotating speed of airlock and main engine according to the feeding quantity and maintain a certain material level, which is beneficial to the micro negative pressure inside the extractor and reduce the solvent leakage.

4.The rotocel extractor is driven by rack, with unique rotor of balanced design, low rotating speed,low power, smooth operation, no noise and quite low maintenance cost;

5.The advanced miscella circulation process is designed to reduce the fresh solvent inputs,reduce the residual oil in meal, improve the miscella concentration and save energy by reducing evaporation capacity.

6.The high material layer of the extractor helps to form immersion extraction, reduce the meal quality in miscella, improve the quality of crude oil and reduce the evaporation system scaling.
