Our processes

It takes a long way to get the cashew into your hand

It takes a long way to get the cashew into your hand. The journey from the farm in Tanzania to the shelf of a shop takes a long time and involves several processing steps.

Harvesting & Sun Drying

Farm level


Cashew apples are usually collected after they have ripened and fallen from the tree. After that they are dried in the sunlight for several days so that they can be stored for processing.

Sizing and Steam cooking

Sizing & Steaming

The first step in processing is sizing the raw cashew kernels into different sizes. Then they are treated with hot steam for 20 minutes in order to prepare them for shelling.


Processing Factory


Now it comes to the very complex process of shelling. At BIOTAN we have automatic machines for this step but also we do manual shelling for the very big kernels and very small kernels which come out unshelled from the machines.

Drying & Peeling

Drying & Peeling

Now the kernels have to be dried so that the testa, a thin skin as we know it from peanuts, can be easily rubbed off in the next step by a machine.

Sorting & Grading

Sorting & Grading

Now the kernels are sorted into different sizes and colors and separated from brokens. Rests of testa are removed and made ready for packaging.

Vacuum Packaging & Shipping
