Features of 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.
Wet Meal Desolventizing Process:
1.Passivate and damage the anti-nutritional components such as the urea enzyme and trypsin in the meal, and
improve 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.
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.
1.Vacuum evaporation features high efficiency, thorough de-solvation and low solvent consumption in crude oil.
2.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.
3.Due to the low temperature of the steam, the crude oil features light color, good quality and low residual solvent.
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. Noncondensable 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-temperatured cold
water to recycle most of solvent gas.The tail gas with little solvent goes to paraffin recovery process.
