Drying characteristics of paddy (long grain variety
PR-118 procured from PAU, Ludhiana) in an integrated
dryer using single as well as combined heating
source was studied at different air temperatures. The
integrated dryer comprises three different air heating
sources such as solar, biomass and electrical. Drying of
paddy occurred in falling rate period. It was observed
that duration of drying of paddy from 22 to 13 % moisture
content (w.b.) was 5–9 h depending upon the source
of energy used. In order to select a suitable drying curve,
six thin layer-drying models (Newton, Page, Modified
Page, Henderson and Pabis, Logarithmic and Wang and
Singh) were fitted to the experimental moisture ratio
data. Among the mathematical models investigated,
Wang and Singh model best described the drying behaviour
of paddy using solar, biomass and combined heating
sources with highest coefficient of determination (r2)
values and least chi-square, χ2, mean bias error (MBE)
and root mean square error (RMSE) values. However,
Page model adequately described the drying behavior of
paddy using electrical heating source.
