%X The present work deals with the study of the thermal performances of a
convective dryer for fruits and vegetables. This dryer, operating with energy
gen<span>erated from the combustion of biomass in a
boiler connected to a water/air heat exchanger could be a solution to the
problematic of energy related to</span> <span>drying.
An experimental and theoretical study is carried out on the</span> temperature
profile inside the dryer. For this purpose, 10.3 kg of tomato</span><span style=\"font-family:&quot;\">es</span><span style=\"font-family:&quot;\"> were
dried on the experimental setup. The operation lasted about 16 hours and
reduced <span>the moisture content from 93.8% to
12% in wet basis. The overall thermal efficiency of the convective dryer during
the trial is 10.76%. For the</span> theoretical <span>study, the dryer components (boiler, water/air exchanger and drying</span> chamber) are first modeled individually; the different sub-programs are then
coupled to form the convective dryer program. The method of global heat
balances combined with the one called </span><span style=\"font-family:&quot;\">¡°</span><i><span style=\"font-family:&quot;\">¦Å</span></i><span style=\"font-family:&quot;\">-<i>NUT</i></span><span style=\"font-family:&quot;\">¡±</span><span style=\"font-family:&quot;\"> is
used. The set of equations is discretized <span>using
the implicit method of finite differences, then solved with the Gauss algorithm
in Fortran 90. The theoretical results obtained are in good agree</span>ment
with those measured.
