SSo Vietnamese farmers waiting for the fruits to fall into groups and then collect them. While waiting, they keep the area below the cashew trees well raked and clear of weeds. Daily collection of cashew nuts together with cashew fruits from the ground.

Step 2: Separating The Cashew Nuts

Then the farmer used the knife to properly separate the cashew nuts from the apple. While separating cashew nut from the cashew apple, shouldn’t leave any part of apple on the cashew nut head. The quality of the nut is affected when the apple is not neatly detached from the nut.

Step 3: Sun-Dry Raw Cashew Nuts

The farmer must dry collected raw cashew nuts in sunlight for a minimum of 2 days. Sun-dry collected nuts on concrete floors, drying mats, or tarpaulins for 2 to 4 days. Turn nuts frequently during the drying period to ensure uniform drying. Sun drying is a traditional drying method for reducing the moisture content of RCN by spreading the RCN under the sun.

Step 4: Storage of Raw Cashew Nuts

Freshly harvested cashew nuts will be dried. Then, screened and sorted according to size. This screening will be useful for cutting and removing impurities such as soil, rock, trash … mixed in cashew. Once sorted, the cashew will be stored in bags and stored in batches. Dried cashew nut must be store in jute bags where its get more air ventilation. The farmers never store cashew nuts in plastic bags because its affects negatively the cashew quality. Cashew nut bags must be store in organized piles on top of the wooden pallets, keeping distance to the warehouse walls. Store well-dried nuts in jute sacks (no plastic or fertilizer sacks containers like boxes, buckets…).

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 in the removal of 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 a period of around 12 hours to let them cool down and help in the removal of 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.

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 kernel is removed from the oven. The 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.

We use cleaning and disinfection cashew nuts machines for reducing or eliminating pathogens, bacteria, and other sources of disease.
