Step 4. Drying Cashew Nuts

Once the cashew nuts have been shelled, they must be dried before they can be roasted and consumed. There are two main methods of drying cashew nuts; sun drying and machine drying.

Sun Drying the Nuts

Sun drying involves laying the cashew nuts out on a flat surface in direct sunlight for several hours. This will help to remove any moisture from the nuts and make them ready for roasting. It is important to ensure that the nuts are not exposed to too much heat, as this can cause them to burn.

The nuts are placed in the machine and then heated with hot air until all the moisture has been removed. This method is often preferred by cashew nut processors, as it is less time-consuming and more efficient than sun drying.
