Investigation of Force Required to Crack Melon Seed Shell by Static Loading


Article Preview

The force required to shell melon seed by static loading techniques was investigated with an experimental rig machine. Melon seeds were categorized based on their moisture content into 4 sub-samples by soaking. Ten seeds from each sample were randomly selected and loaded in three different loading orientations x, y and z. The mean force required to crack the seeds was determined. Results showed variations in force, while analysis of variance showed significant difference in the loading orientation and no significant difference in the interaction of moisture content, at 95% level of confidence.
