Cashews, also known as Anacardium occidentale, are one of the most popular nuts in the world. They are native to Brazil but are now grown in many tropical regions. Cashew nuts are used in various dishes and sweets, and they are also eaten as a snack. However, before cashews are consumed, they need to be shelled. There are two primary methods of shelling cashews: by hand and by machine. In this article, we will explore the process of cashew shelling by hand.
The Process of Cashew Shelling
Cashew shelling by hand is a labor-intensive process that involves several steps. The first step is to harvest the cashew apples from the tree. The apple contains the cashew nut, which is protected by a hard outer shell. The shell is surrounded by a caustic oil that can cause skin irritation and burns, so it is essential to handle the cashew apple with care.
After harvesting, the apples are left to ripen for a few days. Then, the outer shell is removed by hand, revealing the cashew nut. The nuts are then washed and left to dry in the sun for a few days. Once the nuts are dry, they are ready for shelling.
The Tools Used for Cashew Shelling
Several tools are used for cashew shelling by hand. The primary tool is a sharp knife that is used to cut the outer shell of the cashew nut. The knife is held in one hand, and the nut is held in the other hand. The shell is carefully cut, and the nut is removed.
Another tool used for cashew shelling is a pair of pliers. The pliers are used to hold the cashew nut while it is being cut. This helps to prevent the nut from slipping and causing injury to the sheller's hand.
The Benefits of Cashew Shelling by Hand
Cashew shelling by hand has several benefits. First, it is a sustainable method of shelling cashews. Unlike machine shelling, which requires electricity or fossil fuels, hand shelling is powered by human energy. This makes it an eco-friendly option.
Second, hand shelling allows for greater quality control. Each nut is inspected and shelled individually, ensuring that only the highest quality nuts are used. This can result in a better-tasting final product.
The Challenges of Cashew Shelling by Hand
Cashew shelling by hand also has its challenges. The process is time-consuming and labor-intensive, requiring a significant amount of manual labor. This can be challenging for farmers and workers who are looking to increase their productivity and income.
In addition, hand shelling can be dangerous. The sharp knife used to cut the outer shell of the cashew nut can cause injury to the sheller's hand if not handled properly. The caustic oil surrounding the shell can also cause skin irritation and burns if not handled with care.
Conclusion
Cashew shelling by hand is a traditional method of shelling cashews that has been used for centuries. While it is a labor-intensive process that requires a significant amount of manual labor, it also has several benefits. Hand shelling is a sustainable and eco-friendly option that allows for greater quality control. However, it also has its challenges, including the time-consuming and dangerous nature of the process. Overall, cashew shelling by hand is a vital part of the cashew industry and is an essential skill for farmers and workers in cashew-producing regions.
