Solvent pumps: Continuously spray solvent to the rotary-typr extractor.

Roary extractor: Spray and soak the soybean cake with solvent so that oil fats can be dissolved in solvent(from miscella). After processing, you can get wet meal and miscella(mixed oil).

DTDC: Used to separate the solvent from the wet meal.

Miscella tank 1st: Pump the miscella(oil with solvent) into the miscella 1st, then add 10% saline water to it. The phospholipid and impurities in the miscella.

Miscella tank 2nd: The purified miscella will be pumped into it.

Miscella stripping: It will remove the remaining solvent in miscella. And the solvent will be discharged to condenser for recycling.

Condensers: Used to cooling the solvent gas separated from the wet meal and miscella for recycling.

3. Main Process Introduction about Professional Palmkernel oil solvent extraction workshop machine,processing equipment,solvent extraction produciton line machine

a. Qi'E Rotocel Extraction:

1). 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;

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.

b. Wet Meal Desolventizing Process:

1). Passivate and damage the anti-nutritional components such as the urea enzyme and trypsin in the meal, andimprove meal value in use.

2). Control the protein denaturation degree in the meal , and improve the NSI index effectively.

3). It can better regulate the color, flavor and taste of the meal.

4). It can better reduce residual solvent in the meal and regulate the meal moisture, so as to guarantee the minimum solvent consumption and safe use of the meal.

c. Negative pressure evaporation process:

The liquid from the extractor is the miscella containing grease and oil, which can be separated out according their different vaporization temperatures. Our company mainly uses vacuum evaporation technology, and it can reduce solvent leakage and consumption. The separated solvent vapour is cooled and recycled back to the extractor for reuse, which can improve the solvent efficiency.

d. Solvent condensation & recovery process:

Solvent condensation system combines with evaporation system closely, and evaporative condenser and steam stripping condenser all work under negative pressure. Non-condensable gas enters the energy saver from the shell of the first evaporator. In energy saver, non-condensable gas exchanges heat with condensate from the evaporative condenser. Finally, the condensate temperature discharged from energy saver is increased, and the solvent separated from water goes to solvent holding tank. The high temperature makes it unnecessary to be reheated for the recycling, so as to save energy.

Non-condensable gas from energy saver enters desolventizing condenser, in which a great deal of gas is condensed, and the tail gas is discharged into the final condenser. The solvent gas from the extractor enters extraction condenser, and the non-condensable tail gas enters the final condenser. For the free gas in final condenser, diversion box, holding tank, underground solvent library and miscella tank, cool them with low-temperature cold water to recycle most of solvent gas. The tail gas with little solvent goes to paraffin recovery process.

e. Paraffin oil recovery process:

Tail gas first enters paraffin absorption tower, and then comes the counter-current absorption of paraffin and tail gas, which can reach the ideal state when the stainless steel packing has large surface area. The solvent content in discharged liquid paraffin (called rich oil) is not more than 5%, so as to ensure the maximum absorption rate.

The paraffin rich oil is pumped into the heat exchanger to exchange heat with paraffin lean oil, and then goes to paraffin heater, and finally enters paraffin analysis tower. In the analysis tower, the steam-liquid heat exchange is conducted on the surface of stainless steel packing surface with direct steam and rich-oil paraffin, which can remove the solvent in the paraffin. This kind of paraffin, also called lean oil, exchanges heat with rich oil, and then is cooled to the ideal absorption temperature through the cooler. Next, it enters absorption tower for recycling. The gas mixture from the analysis tower enters energy saver, and the tail gas from the absorption tower is discharged from workshop with the fan.

In solvent recovery system, the solvent enters the holding tank through water tank, and the condensed waste water is discharged from water tank. If the tail gas contains certain solvent, cook it with the cooker to make it meet the emission requirement.
