Product description
Cotton Seed Oil Pressing/ Processing line Machine
The whole cotton seed oil making machine contains three workshops: cotton seed pretreatment and prepressing workshop, cotton seed oil extraction workshop and cotton seed oil refining workshop.
1. Cotton seed oil pretreatment and prepressing workshop
cotton seed- magnetic box -cleaning-crusher-flaking roll-cooker-oil prepressing - to extraction workshop
Main Equipments:
1. cotton seed : It's a kind of main oil seeds. It's used to make cotton seed oil around the world.
The oil content in peanut seed is about 48-55%.
2. Magnetic box: Clearing the iron impurity which might be in the cotton seed. Since in the process of puffing, the iron impurity will be harmful to the screw of extrusion machine, affect the puffing effect.
3. Cleaning: This parts have different size cleaning sieves to clean the different impurities. After going through this part, most of the impurities are moved from cotton seed.
4. Crusher: Because of the big size of cotton seed, it need to be crushed to small pieces. The crusher will help to get more cotton seed oil from the seeds.
5. Cooker: This machine can adjust the water content of the cotton seed. It's also good for the prepressing and oil extraction section.
6. Prepressing: This machine is used to take parts of the oil in the cotton seed first, because the high oil content. Then the crude oil will sent to oil refinery workshop, and the cake will sent to oil extraction workshop.

Main Equipments:
1. Solvent pumps: continuously spray solvent to the rotary-typr extractor.
2. Roary extractor: spray and soak the pre-pressed cake with solvent so that oil fats can be dissolved in solvent (form miscella). After processing, you can get wet meal and miscella (mixed oil).
3. DTDC: used to separate the solvent from the wet meal.
4. Miscella tank 1st: pump the miscella ( oil with solvent) into the miscella 1st, then add 10% saline water to it. The phospholipid and impurities in the miscella will react with the saline water, at last the reactant precipitate, reaching the goal of purifying.
5. Miscella tank 2nd: the purified miscella will be pumped into it.
6. Miscella stripping: it will remove the remaining solvent in miscella. And the solvent will be discharged to condenser for recycling.
7. Condensers: used to cooling the solvent gas separated from the wet meal and miscella for recycling.
Crude cotton seed oil -degumming and deacidification-decolorization-deodorization - refined cotton seed oil.
Main Process:
1. Degumming and deacidification: The gumming is moved by phosphoric acid and hot water. There are two ways to move the acid in theoil. One is chemical way, the other one is physical way. The chemical way is using NaOH to react with acid. This way is suitable for the capacity of 5-30T per day. The physical way is using steam and centrifugal to move the acid. This way is used for capacity from 30-2000T per day.
2. Decolorization: This step is used to adjust the color of the oil. You can control the color of the oil according to the requirement of your market.
3. Deodorization: The function of this step is to move the special smell in the oil. This is an important standard for refined oil. Because of the good smell of oil, you can choose this step according to your market.
