    Design, Fabrication and Testing of a Fragmentation Unit to Enhance Palm Kernel Separation

    Paul Okoko; Anietie Akanga; Kingsley Umani
    This study was conducted to enhance kernel separation by dry method using a designed fragmentation unit that would fragment shells with little damage on the kernel wholeness. This would facilitate easy separation of cracked of cracked nut mixture to obtained high percentage of purity kernels when suitable sieves are used. Samples of cracked palm nut mixtures having a moisture content of 3.8% were obtained from a mill and were subjected to repeated impact in a designed fragmentation unit. Sieve aperture sizes of 12 mm, 8 mm, 6 mm, and 4 mm were incorporated in the designed machine to test the shell fragmentation efficiency. Data were obtained and were used to analyze for kernel purity, kernel recovery and percentage of split kernels and shell fragmentation efficiency. Result showed that the machine efficiency in terms of kernel purity was 97.9%, shell purity 95.9%, kernel recovery 98.2%, wholeness of kernel retention 96.5%, split kernel 5.4% and shell recovery 98.6% and the separation efficiency of 96.9%
