Please kindly inform us your required daily capacity, treated quantity, raw material, covering space and related data,so that we can make flow chart cottonseed oil production line for you as your requirement. we will stand at your point to suggest low cost and suitable production line for you. Sincerely want to cooperate with you.
Cotton seeds account for around 65% of the weight of the cotton seeds. When de-linting cotton seeds, you should try to increase the lint yield and reduce the crushing rate. In order to ensure the quality of the short lint, the lint yield of the first lint is controlled at 2-2.5%, and that of the 2nd and 3rd lint at 3-3.5%.
Technological process introduction:
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.
Cleaning: (wind sorting, magnetic separation) Purpose: to improve oil yield, oil cake and by-product quality; to increase oil yield and reduce losses; to increase equipment handling capacity; to reduce wear and tear on equipment; to ensure safe workshop production
Shelling: Different methods of shelling are used according to the different characteristics of the oil hulls, their shape and size, and the attachment of the hulls to the kernel.
1. By means of surface rough rubbing effect, make oilseed shells broken, such as disc type shelling machine, peanut shells, rapeseed shells
2. Crushing by impact with the wall. Such as centrifugal shelling to break sunflower seed shells, oil palm fruit shells
3. Crushing of oil materials by means of extrusion and shearing of the tooth rollers. Such as tooth roller shelling of cotton seeds, castor seeds, sunflower seeds, soybeans, etc.
Separation of shells and kernels: After shelling, cotton seeds are a mixture and these mixtures must be separated. The kernel goes into softening or germ rolling.
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:
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.
