Experimental Study of Papaya Drying in an Indirect Solar Dryer in Natural Convection
Current Journal of Applied Science and Technology,
Papaya is a fruit that is prized for its flavor and also for its different appearances. It is seasonal and easily perishable in our climatic conditions. This work is devoted to the improvement of conservation techniques such as drying. We conducted our experimental work in an indirect solar dryer in natural convection under real (random) climatic conditions and the curves are plotted and adapted using the MATLAB calculation software.
The results obtained show that for slices of papaya 1 cm thick dry less quickly than that of 0.5 cm thickness.
The Gaussian is the model that best adapts to drying curves. The effective diffusion coefficient for 1cm thickness is Deff = 6.80.10-10m/s2.
