Shandong Leader Machinery Co.,ltd. the crude oil is output by the oil feed pump from the oil tank, and cottonseed oil manufacturing process next enters the crude oil heat exchanger to recover part of heat cottonseed oil manufacturing process after metering and then is heated to the required temperature by the heater. After that,cottonseed oil manufacturing process is mixed with the metered phosphoric acid or citric acid from phosphate tank in the gas mixture (M401), and Turnkey project Rapeseed oil pressing factory then enters the conditioning tank (R401) to make the non-hydratable phospholipids in oil change into the hydratable phospholipids. Add the alkali for neutralization, and Turnkey project Rapeseed oil pressing factory the alkali quantity and alkali solution concentration depend on the quality of the crude oil. Through the heater, the neutralized oil is heated to the temperature (90°C) suitable for centrifugal separation to remove the phospholipids, FFA and other impurities in the crude oil. Then the oil goes to the washing process. cottonseed oil manufacturing process there is still moisture in the oil from the wash separator, and the moisture will affect the stability of the oil. So the oil at 90°C should be sent to vacuum drier to remove the moisture
Turnkey project Rapeseed oil pressing factory
Our company is a large-sized joint-equity enterprise which specialize in producing edible oil machanical equipment and it is also a group enterprise integrating scientific research,manufacturing ,sales as one.research institute of machine design company and henan,henan university of technology(formerly the Shandong grain college)school-enterprise cooperation in the oil equipment to carry out long-term,protein extraction,phospholipid extraction,etc R&D and application of new technologies.
1. Rapeseed oil pressing factory
Process Features of JINXIN 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.
6. Specially suitable for the extraction of various pre-pressed meals.

3.Wet Meal Desolventizing Process of Rapeseed oil pressing factory
Desolventizer toaster advantages:
a) Passivate and damage the anti-nutritional components such as the urea enzyme and trypsin in the meal, and improve meal value in use.
b) Control the protein denaturation degree in the meal , and improve the NSI index effectively.
c) It can better regulate the color, flavor and taste of the meal.
d) 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.
4.Negative pressure evaporation process of Rapeseed oil pressing factory
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.

Shandong Leader Machinery Co.,ltd. there is still about 500ppm soap in the neutralized oil from the separator. To remove the remaining soap, cottonseed oil manufacturing process add into the oil about 5~8% hot water, with water temperature 3~5 °C higher than the oil generally. Turnkey project Rapeseed oil pressing factory To achieve more stable washing effect, add phosphoric acid or citric acid when washing. The re-mixed oil and water in the mixer is heated to 90-95°C by the heater, and Turnkey project Rapeseed oil pressing factory then enters the wash separator to separate the remaining soap and most water. The water with soap and oil enters into oil separator to separate out oil in the water. Further catch the oil outside, cottonseed oil manufacturing process and the waste water is discharged to the sewage treatment station.and then Shandong Leader Machinery Co.,ltd. the dehydrated oil goes to the decoloring process. Finally, pump out the dry oil by canned pump.
