Analysis of solar drying unit with phase change material storage systems

Abstract

In present study, a solar dryer integrated with PCM storage has been modelled for analysing the drying process to describe the characteristics of the product being dried. An equipment model describing the effect of heat and mass transfer in the material on the drying medium has also been developed. The mathematical model has been solved using MATLAB. It has been inferred that this model provides a good prediction of temperature and moisture distribution of material, and temperature and moisture distribution of the drying air along the dryer as well as with time. Also the PCM storage system integrated with solar dryer for drying of fruits and vegetable and other food products is found to be promising low cost option for preservations.
