1. Extraction machine introduction:
(1) Function: Extraction 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.
(3) Main parts: The extraction machine series includes rotary extractor, toaster, 1st evaporator, 2nd evaporator, stripping tower, condenser, etc.
2. Extraction machine main parts:
(1) Solvent pumps: continuously spray solvent to the rotary-type extractor
(2).Rotary 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 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.
3. Extraction machine main process:
(1) The material (for pretreatment) is sent to rotary extraction by the scraper conveyor. The material will extracted by the solvent or mi oil. After this step, we will get meal and mi 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 mi oil from the rotary extraction enters into 1st evaporator and 2nd evaporator, most of the solvent in the mi oil is separated.
(4) The mi 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.
4. Extraction machine advantages:
(1) Adopt stainless steel filed 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;
(2) 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;
(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 advanced miscella circulation process is designed to reduce the fresh solvent inputs, reduce the residual oil in meal, improve the miscella concentration and save enerLD by reducing the evaporation capacity.
(5) 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.
(6) Specially suitable for the extraction of various pre-pressed meals.
