CASHEW NUT PROCESSING

malaysia

Immediately after harvest, raw cashews nuts are processed, which is fundamental to maintain their quality and properties. Farmers separate the drupe from the cashew apple to put them into sun-drying. These raw products are traded and then processed to obtain the cashew nut kernel.

Processing Cashew Fruit (Drupes) into Kernels Generally the processing of raw cashew nuts into edible cashew kernel takes the following steps traditional method: roasting, shelling drying, peeling, grading, quality controls, fumigation and packaging. All these steps have to be conducted with care to obtain good quality and good grade kernels. In order to ensure the quality requirements an avoid contamination of the cashew nuts, preparation takes place under clean, hygienic, and ideal conditions. The following aspects are cleaned regularly: equipment (tubes, knives, etc.), working and drying surfaces (racks, mats, etc.), personnel clothes, and preparing storage rooms.

The conversion of Rawseeds to cashew Kernels is quite complex and involves a seven day in-process from conditioning of nuts using steam cooking process,de-shelling by automated machine,drying the kernels in steam tray driers,humidifying and conditioning of kernels for peeling of Testa,air peeling using automated peeling machine ,grading cashews to different size by nano sorter and finally hand picked and finished to obtain top line quality.

Steaming: The in-shell cashews are steamed under pressure to soften the shell. This causes the cashews inside to become loose and easier to remove in time.

Shelling: Each cashew shell is split open longitudinally and the cashew inside is immediately taken out by hand.

Drying:The skin on cashews is dried in an owen at low heat for a few hours to loosen the skin.

Peeling: The skin of each cashew is peeled by machines and the cashew is simultaneously visually graded according to quality.

Grading:The whole cashew kernels are individually graded by hand according to count per pound.

Quality Inspection : The cashews of each grade are inspected according to the present quality standards for that grade.
