Modeling of Some Related Parameters for Cracking Palm Nut in a Centrifugal Cracker

Abstract:

In this study, the principles underlying the energy involved during cracking in a vertical centrifugal nut cracker was analyzed. This will help to elucidate the relationship between various parameters that are relevant to the design and operation of the centrifugal nut cracker for the Tenera and Dura varieties. Experimental analysis was then carried out for each of the two varieties. Each variety was classified into size ranges based on their geometric mean diameter (GMD). Technical analysis revealed that the revolution per minute required by the rotor disc of a centrifugal nut for effective nut cracking is influenced by rotor disc radius (r) and nut dimensions (d₁, d₂, d₃).The modeled equation developed could be used for predicting nut translational kinetic energy required to crack dried nut of the Dura and Tenera varieties to release high percentage of whole kernel.
