As a result, the drying rate of
red chilli in the drier was found to be higher than that of
in open sun. The drying rate of improved sun drying sample
was found higher than that of conventional sun drying
sample although they were both dried in the open sun. This
is due to the fact that the sample of improved sun drying
method was blanched and the tissues of this blanched chilli
was cooked partially and the cell wall of chilli pods became
soft, more permeable to moisture diffusion.
