Abstract
The effects of different drying condition and loading orientation on the compressive failure of cashew nuts (Anacardium occidentale L.) shell were investigated. Cashew nuts of mongrel (mixed varieties) were conditioned at sun drying for 2 days after harvest (2dah), 3 days after harvest (3dah), and 4 days after harvest (4dah) and were compressed in longitudinal, concave up and concave down orientations until rupture using a universal testing machine. Results showed that the longitudinal orientation at 2dah, 3dah, and 4dah required force to rupture the nut but also compressed and damaged the kernels. The drying conditions of 2dah, and 3dah showed that lesser force to rupture the nut is required but it also compressed the damaged the kernels. Visual inspection revealed that cashew nuts that are sun-dried for 4dah subjected to concave up or concave down orientation showed that the that the that the most acceptable method of compression to attain whole cashew kernel. Moreover, the compression of the nut should be within the range of 1.4m to 2.8mm deformation with an applied maximum load of 0.3 kN for concave up or concave down orientation. This is to assure for a whole nut kernel recovery.
