The good corn oil extraction process made in China

1. Corn oil extraction process 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. Corn oil extraction process 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. Corn oil extraction process 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. Corn oil extraction process 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 energy 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.

Shandong Leader Machinery Co.,ltd. the crude oil is output by the oil feed pump from the Oil Fractionation Equipment oil tank, and next enters the crude oil heat exchanger to recover part of heat after metering and then is heated to the required temperature by the heater. After that, The good corn oil extraction process made in China the oil is mixed with the metered phosphoric acid or citric acid from phosphate tank in the gas mixture (M401), and The good corn oil extraction process made in China then enters the conditioning tank (R401) to make the non-hydratable phospholipids in oil change into the hydratable phospholipids. Shandong Leader Machinery Co.,ltd. Add the alkali for neutralization, and the alkali quantity and alkali solution concentration depend on the quality of the crude oil. Through the heater, Oil Fractionation Equipment the neutralized oil is heated to the temperature (90°C) suitable for centrifugal separation to remove the phospholipids, FFA and other impurities in the crude oil. Then the Oil Fractionation Equipment oil goes to the washing process.Oil Fractionation Equipment there is still about 500ppm soap in the neutralized oil from the separator. To remove the remaining soap, The good corn oil extraction process made in China add into the oil about 5~8% hot water, with water temperature 3~5 °C higher than the oil generally. To achieve more stable washing effect, add phosphoric acid or citric acid when washing. Shandong Leader Machinery Co.,ltd. The re-mixed oil and water in the mixer is heated to 90-95°C by the heater, and then enters the wash separator to separate the remaining soap and most water. The water with soap and oil enters The good corn oil extraction process made in China into oil separator to separate out oil in the water. Further catch the oil outside, and the waste water Shandong Leader Machinery Co.,ltd. is discharged to the sewage treatment station.
