Step 5: Steaming Raw Cashew Nuts

The steaming of raw cashew nuts prior to shelling is adopted widely in medium-scale cashew nut processing mills with the help of a boiler. The steaming of raw cashew seeds is carried out by the indirect or direct method of boiling. The indirect method includes the steaming of cashew seeds in a separate cooker, while the direct method includes the placing of cashew seeds at the same place at which water is boiling. The process of steam roasting helps remove this hardshell with minimal effort. These cashew nuts are left in the drum for 20 minutes for proper roasting. The roasted cashew nuts are then taken out of the drum and placed in the open air for around 12 hours to let them cool down and help remove the cashew shells. The boilers used for the generation of steam are of various capacities depending upon the need of any processing unit, which consumes electricity and biomass as a fuel.

Step 6: Hard Shell Cutting

The raw cashew nuts are delivered to the factory to prepare them for cutting shells (hardshell outside – cashew shell) and peeling husk skin. Firstly, after steaming to de-acidify the cashew shell. This process helps to soften the hardshell of cashew nuts. After Steam Roasting is complete, the cashew nuts are cut off by specialized knives to remove the outer shell to get the inner kernel. This is a very difficult stage, requiring skilled workers to separate the shell without breaking the inner core of the cashew nuts (cashew kernel). Usually, the cashew shells will be thrown away like waste, but now they are used to make many useful products. Today, in large factories, people cut cashews by machine.

Step 7: Drying Cashew Nut Kernels

In order to keep the cashew nut long time, we can make dried under the sun or use the drying machines. The moisture is 3-5% suitable with export standards and keeps it longer. Besides It also removes the testa of cashew nuts easier.

Step 8: Peeling The Testa

The inner shell of the kernels has to be removed to produce the white nuts. The peeling process is designed to remove this inner softshell after the cashew kernel is removed from the oven. The cashew kernel is used for peeling after it is left in the open for a period of 12 hours. This cooling helps in the peeling process. Each nut is individually peeled to get white nuts. These white nuts are then sent to the grading department.

Step 9: Color Sorting Cashew Nut Kernels & Quality Control Cashew Nut

The process of grading is designed to sort the white cashew kernel into different grades. The white kernel is divided into two main types wholes and pieces. The process of sorting wholes and the pieces are based on the size, color, and texture of the nuts. The sorting is done based on the set international sizes (AFI Standard For Cashew).

In weather (rain, snow…), the cargo must be protected from moisture, since it may lead to mold, spoilage, and self-heating as a result of increased respiratory activity. Hooks shouldn’t be used with bagged cargo, so as to prevent damage to the bags and loss of volume.
