The drying industry has been growing considerably due to the great demand to have non-perishable food. Convective drying is one of the most popular equipment on drying industry (food, chemical, pharmaceutical, etc.). One of the drawbacks of this equipment when it is used for convective drying, is the non-uniformity in the final product quality. This study presents the development of a mathematical model trough Computational Fluids Dynamics (CFD). The drying chamber of a heat pump dryer is assessed from a drying air velocity and temperature profiles perspective. The model was developed solving different transport phenomena related equations. The established procedure was set up with the aim of evaluating the distribution of drying air velocity and temperature on the drying chamber to define the need of redesigning it. The profile results of the air velocity and the temperature show that, in fact there is a need to redesign the chamber. Only trays 2, 3, and 4 are the ones that could achieve the drying of the products. The proposed solution is to implement air distributors or to modify the tray positioning to make the distribution of the drying air and temperature homegeneous.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
