Pretreatment of cottonseed before pre-pressing and extraction can make cottonseed have better oil production and reach a better state, to speeding up the oil yield of cottonseed and meeting the requirements of cottonseed oil production processes. The cottonseed oil pretreatment machine process mainly includes cleaning, shelling, kernel shell separation, flaking, cooking, etc. The equipment used mainly includes air separator, shelling machine, kernel shell separation screen, flaker, and cooking pot. The following is the purpose of cottonseed oil pretreatment and cottonseed oil pretreatment process.

 

The main purposes of cottonseed oil pretreatment machine are:

 

1. Reduce oil loss and speed up oil production rate.

 

2. Speed up the purity and quality of by-products of oil cake and meal machine.

 

3. Reduce wear and tear on cottonseed oil machine and extend service life.

 

4. Avoid production accidents and speed up the reasonable processing capacity of cottonseed oil machine; reduce dust and improve the workshop environment to ensure stable production.

 

1. Firstly need to use an air separator to remove light impurities, heavy impurities and stone impurities in the cotton seeds.

 

2. Then use a shelling machine to remove the cottonseed shell, and use a kernel shell separation screen to separate the kernel shells to obtain cottonseed kernels.

 

3. Afterwards, flaker is used to press the cottonseed kernels into thin slices to increase the surface area of the oilseed, destroy the cell structure of the cottonseed, shorten the oil path, and speed up the oil yield.

 

4. Finally, the thin slices are cooked to adjust the temperature and moisture to reach the appropriate temperature and moisture before pressing.

 

The above is the pretreatment process of cottonseed. GREAT provides complete sets of cooking oil production line machinery, and can customize machine according to customer needs.
