Cottonseed oil project, the whole cottonseed contains 15% - 25% oil, and its kernel contains 32% - 46% oil and 30% protein, so it is an important source of edible oil and plant protein. Cottonseed oil contains 60% - 90% unsaturated fatty acids (linoleic acid and oleic acid), which can reduce cholesterol and prevent arteriosclerosis. It is also an important edible vegetable oil.

Generally speaking, cottonseed oil processing mainly includes flow production process, which includes seed cleaning, cracking, peeling, cooking, discharging and refining.


Production technology of cotton seed oil project:

Cottonseed → cashing → shelling → peeling → extrusion → extraction → mixed oil → steam (concentration of mixed oil 65-70%), acid reaction → alkali reaction → heating → centrifugal separation → twice steam production → stripping → neutralizing cottonseed oil → decolorization → deodorization → refining cottonseed oil

1.Cleaning: in this section, we use electromagnetic separator, vibrating screen, paraffin remover and degumming agent (cottonseed is used for hammering degumming agent). By removing impurities, the loss of oil can be reduced, and the oil production and the environment of production plants can be improved. The impurity content in the pretreated material is less than or equal to 0.1%.

2.Cracking: using toothed cracking roller to cut Cottonseed Kernel into suitable uniform pieces, which can keep moderate block size, so as to extract oil.

3.peeling: cut the cracked Cottonseed Kernel into even small slices, with thickness ≤ 0.5mm, less powder and no oil leakage. Gently knead it with hands, and the fine powder ratio less than 1mm sieve hole shall be less than 10% - 15%.

4.Cooking: the process involves adding steam to the crushed / flaky seed slices and then drying the seeds to remove more moisture.

5.Expulsion: more oil can be obtained by matching with modern oil drainage press, or solvent can be used to obtain more oil after preloading by oil drainage press. Solvent extraction is a common commercial technology for oil recovery from oilseeds.

6. Refining: crude oil contains residues and solid powder, so we must remove them before packaging or refining.

Advantages of cottonseed oil project:

1. High oil production and obvious economic benefits.

2. The rate of residual oil in dry powder is low.

3. Improve the quality of cooking oil.

4. Low processing cost and high labor productivity.

5. High automation and labor saving.
