LD advanced cotton seed oil extraction plant, solvent extraction production line
Brief process of complete oil production line:
Main Equipment: Rotary multi cell extractor with stainless steel gate or drag chain extractor, D.T.D.C desolventizer-toaster, negative pressure evaporator, paraffin recovery equipment, etc.
Details: The oil seed extraction production line designed by LD uses advanced process design, with easy installation of equipment, safe characteristic and automation, small energy consumption, good effect of extraction, low residual oil in meal, and good quality of meal and oil.
About solvent extraction:
Solvent Extraction is a method to process materials using a kind of solvent to separate some components from the raw material. It refers to the process of extracting oil from oil bearing materials by means of solvent, a chemical way to extract oil. The cake from oil press section could also be used as raw material for solvent extraction plant.
Solvent Extraction, as the name suggests, is a process to extract the oil from oil bearing materials by means of solvent, and the normal solvent is Hexane-a kind of prtroleum by-product. The design of LDâÃÂÃÂe machines is simple, multifunctional and easy to operate. And the LDâÃÂÃÂe Edible Oil Solvent Extraction plants have been operating for more than three decades.
The plant is designed to extract oil directly from oil seed whose oil containing rate is less than 20% oil like soya bean after flaking or it extracts oils from pre-pressed or fully pressed cake of seeds with oil containing rate of more than 20% such as sunflower, peanuts, cotton seed, palm kernel, canola, copra, castor and various other materials.
Features of solvent extraction system:
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.

Oil refining means separating impurity from oil based on the different characteristics of oil and impurity, in order to enhance the stability and security of oil. Oil refining including two technologies, physical refining and chemical refining.echnological process details of LD advanced cotton seed oil extraction plant, solvent extraction production line:
AAA1
1. Acid reaction process
Oil temperature can be adjusted by screw plate heat exchanger. When the temperature is heated to about 80℃, mixing about 85% food grade phosphoric acid into acid reaction tank for reacting. In the tank, most non-hydrated phospholipid transfer into hydrated phospholipid.
AAA1
2. Neutralization process
In the neutral section, degummed oil with appropriate temperature and the appropriate concentration of alkali liquor, into the neutralization centrifugal mixer mixing, in order to achieve the effect of mixed, the mixture is then sent to neutralization tank for enough time, in this process, excessive alkali neutralization of free fatty acids and some phosphate form soapstock , after pumping oil soap mixture into heater oil heating to 85 ~ 90 ℃ in centrifuge separation oil - soap (or oil - glue). Oil soapstock of the separated (or foot) feet into the oil tank, and then to the salting out with soap pump tank isolated part of the oil.
AAA2
3. Washing process
Neutral oil from separator, still contains about 500 ppm soap, in order to reduce the residual content of soap, oil is joined by about 10% of hot water, washed in the washing mixer, hot water will absorb oil soap and other impurities, then in the water separator are separated.
