Vegetable cake solvent extraction

Vegetable cake solvent extraction

Solvent Extraction Process .

After dryging process , we get rice bran with 7 to8 % moisture , then we send the rice bran to solvent extraction process

And Firstly , we need to by the scraper convenyor ,send the rice bran to the solvent extractor , then leach them about 90-120 minutes , keep the temperature is 70to 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 meal ,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 condenser , we recycle use the solvent . It can save our cost .

The detailed process of solvent 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, 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.
