Cottonseed oil extraction plant

Why choose us?

1.More than 60 years cooking oil machine manufacturing experience
2.Have factory and professional engineers
3.Can Offer full set oil production line, according to different oilseeds
4.Patents and CE,ISO,SGS

We are one of TOP 10 Cereals & Oil Machinery Brand Manufacturers in China. This Cottonseed oil extraction plant includes seed oil pretreatment and pre-pressing  machine,  oil cake extraction machine and oil refining machine.

1. oil seed pretreatment and prepressing machine:
seeds→Magnitic seperating( Metal impurities)→cleaning →husking→ flaking roll→Cooking →pressing workshop

Main Equipments of oil seed pretreatment and prepressing machine:
1. Raw material : peanut,soybean, rapeseed,sesame seed ,sunflowerseeds, linseed, pumpkinseeds, cottonseed etc.

2. Magnetic box: Clearing the iron impurity which might be in the seed.The iron impurity will be harmfulto the following machines, so we need take the iron impurities out.

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 seed .

4. Husking: this can help improve the oil yield from seed,and reduce wear to the machine .

5. Flaking:  making use of the mechanical action to flake the seed into flakiness.After flaking, the materials is becoming thiner thank,it is good for absorb moisture and heat in cooking process and it is much easier for getting seed oil in machines for fish oil extraction process.

6. Cooker: This machine can adjust the water content of the seed. It’s also good for oil press and fish oil extraction section

Oil cake extraction machine of cottonseed oil extraction plant:
1. Oil extraction:
Oil extraction is to extract oil from oil oil base or pre-pressed cake to oil mixture and meal.
The major equipment of this section is extractor, and extraction pot is always used in batch extraction while continuous extraction uses loop type extractor, rotocel extractor, crawler type extractor, etc.
2. Desolventizer toaster:
Meal from extractor consists of 25-35% solvent. And in order to recycle solvent and get better-quality meal, wet meal drying is necessary.
And high bed desolventizer toaster is always used in pre-pressed leaching meal, while DTDC desolventizer toaster is always used for direct extraction meal.
3. Oil stripping tower/ oil stripper:
Oil mixture consists meal powder, solvent and oil. This step is to seperate these 3 indreginents by filtration, evaporation, and stripping.The major equipments for this section include filter, cyclone hydraulic separators, evaporator, stripping tower, etc.
4. Solvent vapor condensation and recovery:
Mixed vapor from desolventizer toaster, evaporator, and stripping tower should first be condensed to liquid by condensers, and then seperate solvent and water by water separator, and finally get recycled solvent to reuse in extraction.

Oil refining process of cottonseed oil extraction plant:

Crude oil → degumming and deacidification→ decolorization →deodorization → refined  oil.

Main Process of cottonseed oil refining machine:

1. Degumming and deacidification: The gumming is moved by phosphoric acid and hot water.

2. Decolorization: This step is used to adjust the color of the oil.

3. Deodorization: The function of this step is to move the special smell in the oil.
