Modeling of carrot thin layer convective drying process

The effects of different dehydration temperature (35, 50 and 70 °C) and carrot slice thickness (3, 6, and 9 mm), at the constant (hot) air speed and mass load, on moisture ratio (MR) and drying ratio (DR) in thin layer convective drying process were investigated. The mathematical models Modified Pag...

Description
Summary:The effects of different dehydration temperature (35, 50 and 70 °C) and carrot slice thickness (3, 6, and 9 mm), at the constant (hot) air speed and mass load, on moisture ratio (MR) and drying ratio (DR) in thin layer convective drying process were investigated. The mathematical models Modified Page, Logarithmic, and Two-term models (for MR), and Gauss Modified model (for DR) were the most appropriate. Based on the obtained results for the R2 and RSME, the optimal parameters for thin layer drying carrot slices in laboratory dehydrator are dehydration temperature 70 °C, and carrot slice thickness of 3 mm, with the shortest dehydration time of 4.5 hours and the maximum DR of 106.7 g/h.
