Solvent recovery
Solvent Extraction Process
After pressed or pre-pressed , we get the cake , the cake has about 7% or 12-13% oil residual . In order to make the oil in the cake is less than 1% , we need to solvent extraction .
And Firstly , we need to by the scraper convenyor ,send the cake to the solvent extractor , then leach them about 90-120 minutes , keep the temperature is 70-80 degree . Then we can get the two parts by this process .
1. One is wet meal . The meal has the moisture and solvent . Then we need to Desolventizing this . Keep the solvent at 500ppm
in the cake ,and moisture is 12.8-13.2 % .
2. Another is Miscella . Then the miscella has much solvent and impurities . We also need to wipe off the solvent and impurities.
Then we can get the second grade oil .
3. Third part is solvent recycle . After we make the solvent change vapor , Then by the condensor , we recycle use the solvent
oil .
It can save our cost .
4. Paraffin oil recovery process .
The detailed process of solvent extraction
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.
Part of Desolventizer
Desolventizer toaster advantages:
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.
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. Its rotocel extractor is driven by rack, with unique rotor of balanced design, low rotating speed, low power, s
mooth 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.
Negative Pressure Evaporation Advantage:
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.
