Vacuum drying processes were completed between 3 and 19.17 h. In this study, measured values were compared with predicted values obtained from twenty one thin layer drying theoretical/semi-empirical/empirical equations. Models whose coefficient of correlation (R2 ) values are highest were chosen to be the best models. According to this, the best models of combined 50°C temperature with vacuum levels (0.05, 7 and 13 kPa) was found to be “Modified Henderson & Pabis” Model, combined 75°C temperature with vacuum levels (0.05, 7 and 13 kPa) was found to be “Alibas” Model.eninfo:eu-repo/semantics/openAccessChili pepperVacuum dryingMoisture contentThin-layer drying modelsArticle161170617
