Design, construction and performance evaluation of a new laboratory convective dryer

Aiming to overcome the lack of experimental data in the open literature and the necessity to validate numerical models which are an essential tool for optimization and increase the efficiency of the drying process, a laboratory convective (LC) dryer has been designed, constructed and equipped with a...
