The advantages of fluidized bed drying can be summarised
as follows: (i) high heat and mass transfer rates, because of good
contact between the particles and the drying gas, (ii) uniform temperature
and bulk moisture content of particles, because of intensive
particle mixing in the bed, (iii) high drying capacity due to
high ratio of mass of air to mass of product [17]. The better heat
and mass transfer greatly reduce drying time without considerably
damaging heat-sensitive materials [18]. Uniform drying results in
bed product quality. Carrots dried by fluidized bed drying showed
better colour, rehydration properties, greater b-carotene retention
