First, the history of cashew nut shelling
The origin of cashew nuts can be traced back to Africa, and the earliest cashew nuts grew wild in Africa. Later, cashew nuts were introduced to India and Brazil and became important local agricultural products. However, at that time, cashews were sold in shells and consumers needed to shell them themselves. This situation continued until the beginning of the 20th century.
At the beginning of the 20th century, with the development of mechanized production, cashew nut sheller came into being. This machine can remove the shell of cashew nuts and then separate them, thus making it convenient for consumers to eat. The appearance of this machine greatly promoted the production and sales of cashew nuts, and also laid the foundation for the international trade of cashew nuts.
Second, the status quo of cashew nut hulling
Nowadays, shelling cashew nuts has become a common production method, and almost all cashews are shelled. The advantage of this method is that it can greatly improve the production efficiency and reduce the production cost, and it is also convenient for consumers to buy and eat.
The specific cashew nut shelling steps are as follows:
1. Put the cashews into the sheller, and the machine will automatically remove the shells of cashews.
2. Cashew cashews will be separated, and then cashews of different sizes will be separated by vibration screening.
3. Finally, the separated cashews are cleaned, dried and packaged for sale.
It is worth noting that although cashew nut hulling can improve production efficiency, there are also some problems. For example, the shelling machine may damage the nutritional components of cashews, thus affecting the taste and nutritional value of cashews. In addition, the shelling machine may also produce some noise and pollution, which will have a certain impact on the environment.
