WHAT ARE THE SOLVENT EXTRACTION MACHINES LIKE?
ABOUT QI'E SOLVENT EXTRACTION SYSTEM:
Rotocel extractor:
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.
Evaporation process:
Advantage of Negative pressure evaporation
1. Chinese manufacturer for extraction solvents plant evaporation features high efficiency, thorough de-solvation and low solvent consumption in crude oil.
2. Due to the low temperature of the steam, the crude oil features light color, good quality and low residual solvent.
3. Use the second steam of desolventizer toaster and remaining steam from steam jet pump as the heat source of the first steam, which can save energy, reduce the condenser configuration area and save investment.
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.
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.
