In this work we studied the solar hybrid drying of sliced potatoes by forced convection in indirect solar dryer
using extra energy via a heater by joule effect generated by photovoltaic modules connected in parallel. The main
results show that:
With the use of one solar panel to reach the final water content of the potato ( xf= 0.13kg w /kg d m) the drying
time obtained was 3H. In case of two panels this time was found 2H45mn
The operating condition ensuring a better result was found as mentioned bellow:
by hybrid (solar, photovoltaic ) with an optimization of the number of connected solar panels /drying
duration /quality at a maximal circulating drying air speed of 0.51m /s 2h45mn
by Hybrid drying (conventional electric power) using a maximum speed, performed at: 0.5 m/s in duration of 1 h
15min through the period between Mai 13th, 2012 to Mai 18th, 2012
