Cotton seed oil content is 16%-27%.The shell of cotton is very solid,before making the oil and protein have to remove the shell.The shell of cotton seed can be used to produce furfural and cultured mushrooms.Lower pile is the raw material of textile,paper,synthetic fiber and nitration of the explosive.
I. Technological process introduction:
(1) Pre-treatment flow chart:
Before the oil plant solvent extraction,it need different mechanical pretreatment、hot pretreatment and thermal refining which called pretreatment.
Cotten seed → Metering→Winnowing → Husking→Flaking→cook→Pressing→Cake to solvent extraction workshop and Crude oil to refining workshop.
(2) Main process description:
Cleaning process: Shelling
The equipment is comprised of ftransmission mechanismeeding apparatus、magnetic separation、crushing、Roller spacing adjusting 、engine base.The machine has large capacity 、small floor space、lower power consumption、easy to operate、high shelling efficiency.roller shelling is no less than 95%.
Kernel husk separator
It is mixture after shelling of cotten seed.The mixture includes full oil seed without any crushing,seed shelled and husk,all the mixture must be separated.
Technically,the mixture must be divided into kernal,husk and seed.Kernal will go to the process of softening or flaking section.Hush will go to storeroom or package.the seed will go back to shelling machine.
Flaking: Flaking means a certainty granularity of soy lamella was prepared for flaked of about 0.3 mm, the oil of raw material can be extracted in the shortest time and maximum, and residual oil was less than 1%.
Cooking: This process is heating and cooking for rapeseed which is easy to separate of oil and can provide the oil quantity from prepress machine.It is easy to operate and have long life.
Oil pressing:Our company screw oil press is big scale continuous press equipment, pass ISO9001-2000 quality certification, can produce cotton seed, rapeseed, caster seed, sunflower, peanut and so on. It’s feature is capacity is big, power consumption small, running cost low, low residual oil.
Solvent extraction process:
Features of Qi’E 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.
Continuous Refining Decoloring Process
The main function of decoloring process is to remove oil pigment, residual soap grain and metal ions. Under negative pressure, the mechanical mixing method combined with steam mixing will improve the decoloring effect.
The degummed oil firstly enters into the heater to be heated to the appropriate temperature (110℃), and then goes to the bleaching earth mixing tank. The bleaching earth is delivered from the low bleaching box to the temporary tank by wind. The bleaching earth is added by automatic metering and is interlockingly controlled with the oil.
The oil mixed with the bleaching earth overflows into the continuous decolorizer, which is stirred by non-powered steam. The decolored oil enters into the two alternate leaf filters to be filtered. Then the filtered oil enters the decolored oil storage tank through the security filter. The decolored oil storage tank is designed as the vacuum tank with the nozzle inside, so as to prevent the decolored oil contacting with the air and influencing its peroxide value and color reversion.
Continuous Refining Deodorizing Process
The qualified decolored oil enters into the spiral plate heat exchanger to recover most of the heat, and next goes to high pressure steam heat exchanger to be heated to the process temperature (240-260℃) and then enters the deodorization tower. The upper layer of combined deodorization tower is the packing structure which is mainly used to remove the odor producing components such as free fatty acid (FFA); the bottom layer is the plate tower which is mainly for achieving the hot decoloring effect and reducing the peroxide value of the oil to zero. Oil from the deodorization tower enters into the heat exchanger to recover most of the heat and makes further heat exchange with crude oil, and then is cooled to 80-85℃ through the cooler. Add the required antioxidant and flavor agent, and then cool the oil below 50℃ and store it. Such volatiles as FFA from the deodorizing system are separated by the packing catcher, and the separated liquid is FFA at low temperature (60-75℃). When the liquid level in the temporary tank is too high, the oil will be sent to the FFA storage tank.
