Optimising cold compressive recovery of oil from the seeds of Sesame (Sesamum indicum L.)

ArticleEffects of the time rate of deformation and aspect ratio on mechanical response and performance in single cycle cold compression scheme were investigated for bulk sesame seeds and response forms fitted using forward stepwise multiple regression technique. The degree of deform ation was dependent on the time rate of its induction and the equipment’s aspect ratio. Energy requirement correlated positively with deformation rate and aspect ratio. Energy expenditure was however more efficient with larger aspect ratios than with small er ones, given the associated volume energy demands. Strain resistance correlated positively with each of the two influence factors. The time rate of deformation was the most important predictor of oil yield and performance. All the fitted forms had highly significant effects in predicting the responses investigated with 76.7 – 99.6% of the behaviours of the system explained. The results are valid within the ranges of the influence parameters investigated

Effects of selected process parameters on the compaction of carob powder

ArticleThe effects of important process parameters on mechanical response during the densification of an industrial food powder were investigated and important phenomena described using the power rule. The factors studied had highly significant effects on mechanical response. The effects of the models in predicting the behaviour of the system were also highly significant. The findings are of relevance to processing and handling of food powders
