Effective moisture diffusivity of onion slices undergoing infrared convective drying
PB Pathare, GP Sharma - Biosystems Engineering, 2006 - Elsevier
Drying experiments of onion slices (6mm thickness) were carried out by using infrared
convective drying. Infrared convective drying of onion slices was observed to be a falling
rate process. The average effective moisture diffusivity of onion slices ranged between 0·
2514× 10− 10 and 0· 3233× 10− 10m2s− 1. The values of average effective moisture
diffusivity increased for the same values of drying air temperature and air velocity as applied
radiation intensity was increased. Average effective moisture diffusivity decreased at all air …
