DRYING OF ASPARAGUS ROOTS IN SOLAR AND FLUIDISED BED DRYER
Journal Title: International Journal of Agriculture Sciences - Year 2017, Vol 9, Issue 13
Abstract
This study presents the drying kinetics of asparagus using solar dryer and fluidized bed dryer at four temperature levels of 40, 50, 60 and 700C. The drying rate was always higher in case of fluidized bed dryer as compare to solar dryer and it was increased with increase in temperature. The maximum drying rate 5.953% d.b./min was observed in fluidized bed dryer at 70oC in the first 60 min. Three thin layer drying models were fitted to the experimental data of asparagus. The best model to predict the moisture content of asparagus in thin layer was found to be Page equation. Color of asparagus was slightly changed after drying. The power consumption was found lower for fluidized bed dryer as as compare to solar dryer. The rehydration ratio was maximum of 5.745 for fluidized bed dryer at 600C and dehydration ratio was maximum 7.092 for solar dryer at 700C.
