Resumen
he high indices of pollution reached by the energy use fossils are sufficiently preoccupying in the present.
Actually, the development of new technologies that can use renewable energy sources is quite important. Solar drying of cashew pulp is a viable alternative to take care of to the producers that with the use of this technology will be able to add value for theirs products and to minimize its losses postharvest. In this direction this work had as objective the study of the solar drying of cashew pulp using solar dryer of indirect radiation. Experiments in a unit had been carried through pilot of solar dryer under forced convection, using slices of the cashew pulp with thicknesses of 1cm. Later, a fenomenológico mathematical model was developed to simulate the solar dryer and to analyze the behavior of this front to the pertinent variable of the process. The final model is represented by a system of partial distinguishing equations the two phases (first solid and phase gás) and integrated numerically for the method of the lines. The results gotten with the simulation had been validated with the experiments and, the same ones had revealed condizentes with the data solar drying of cashew pulp
