| Acoustic impulse responses of young coconut fruits were analyzed using Fourier analysis and the correlation of signal characteristics with the mucous-like stage, cooked rice-like stage and leather-like stage maturity levels was determined. Analyses of sound signals of unshaved and shaved fruit samples were performed to determine if the difference in acoustic response could help enhance the differentiation of the fruits at different maturity levels. Results of statistical analysis showed that the frequency of the impulse response of the unshaved fruits increases with maturity levels and are significantly different from each other, while those of the shaved fruits are not. Also, results of regression analysis showed that as the fruits mature and the meat or... |

| A mechanical pili nut cracker that used gradual compression for cracking was proposed and developed. This was a deviation from the traditional practice of applying impact for cracking pili nuts. The cracking unit of the machine accomplishes gradual compression by a rotating assembly of discs and compression bars travelling along an arrangement of cam rails. The cracker’s performance was established using pili nuts at different moisture levels. The tests followed a single-factor three-level experiment where the response variables included cracking capacity, cracking efficiency, cracking recovery, whole kernel recovery, kernel damage, kernel losses and purity of output. The machine performed satisfactorily using nuts dried for three days after... |
