Cottonseed hulls are usually divided into three types: large, medium and small, or according to the amount of cotton wool, they are divided into large, medium, small and thin, and even called "iron shells". The amount of cashmere depends on the time when the raw cotton seeds are short. If the market price of cotton short staple is high and sells well, the manufacturer will cut off as much short staple as possible.

In the cultivation of edible fungi, there is little difference in the size of cottonseed shells in terms of yield. Because many oil plants will produce big shells and crush them into small shells to meet the cultivation requirements. Mainly reflected in the technical requirements of bagging density in the process of edible fungi cultivation: the bagging density of small shells is too high, which will lead to poor ventilation; And the cultivation bag is easy to be damaged when the big shell is bagged.

Extended data:

Cottonseed hulls are agricultural and sideline products obtained after cottonseed hulling, and they are a kind of high-quality forage. Cottonseed hull is rich in cottonseed kernel, which has good palatability and is eaten by sheep. Long-term human feeding is easy to cause poisoning and even death, mainly animal poisoning caused by VA calcium deficiency.

Cottonseed hull is the shell left after cottonseed is separated by sheller. Because of its high cellulose content, it is widely used in livestock feed processing and breeding edible and medicinal bacteria. In Xinjiang, cottonseed hull resources are extensive and rich.

Cotton seed hulls can be carbonized directly, and the process is simple and safe, and various forms of nitrogen-doped porous carbon materials can be prepared without adding templates for post-treatment and other steps. Compared with the traditional preparation method of carbon materials, this method has the advantages of low cost, stable and uniform raw material components and no need for complex component separation.

The electrode material prepared from the nitrogen-doped porous carbon material shows excellent performance in supercapacitors. In addition, the nitrogen-doped porous carbon material has excellent dye adsorption performance and can be used as a new functional material for adsorption and separation.
