Available oil crops
The techmology of my company for pretreatment and pre-pressing which mainly include the cleaning , decrustation extrusion,flaking,cooking and pre-pressing and so on .Considering the different characteristic of oil seeds and the customer requirements,we can provide you the special design,in order to adjust the oilseed to the optimun state ,which will improve the oil yield and the cake quality.
Pretreatment process feature:
1) Different combinations of process can process various oil plants in one workshop.
2) Use special intensified pretreatment technology for aroma peanut oil to make it more aroma.
3) Adopt advanced and reliable shelling technology to meet higher requirements for protein content in meal.
4) Extrusion treatment is used for raw materials with hard extraction, large-sized powder, and large capacity, which can reduce residual oil and solvent consumption, and increase the capacity by 50-80%.
5) The new technology of shelling and low-temperature treatment can ensure high protein and least denaturation.

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.
Desolventizer(DTDC)
Solvent condensation & recovery
Main Parameters
Residual oil in meal |
≤1% (Peanut) |
Solvent consumption |
≤3Kg/T(6#solvent oil) |
Crude oil moisture and volatile matter |

The advantage of DTDC desolventizer
1, Passivate and destruct the anti-nutrition in the meal, such as the urease and the trypsin,improve the use value of the meal.
2, Control the protein denaturation degree of the meal, effectively improve the meal’s NSI index
3, To adjust the color, flavor and granularity of the meal.
4, To reduce the residual solvent in the meal, adjust the moisture of the meal, to ensure the lowest solvent consumption and safe use of meal in production.

1.Deacidification
Sodium hydroxide antagonize free fatty acids,and subside phospholipids,to remove the insoluble impurities,then after the separation of soapstock, neutral oil was washed in soft water,last drying in vacuum.
2.Decoloration
Used to remove off pigments, bleaching oils and grease dehydrate
3.Deodorization
Using high temperature and high vacuum steam stripping method deodorization temperature commonly 180, vacuum degree 9.3 104 Pa can achieve ideal results
4.Dewaxing
Dewaxing can ensure the colour of the oil to be clear bright at room temperature and frozen temperature. to reduce the oil in the wax content to 10 parts per million to get crystal clear oil.
