Abstract

Hybrid drying technology was developed for improved performance and quality of products. The main parts are: a PV thermal collector (PVAC), a desiccant silica gel bed (DB) and an IR drying chamber. This paper presents the technique and a quality comparative analysis of ginger drying between convection drying alone (HA), convection combined with IR (HA-IR) and Hybrid (HB). Experimentation was compared with and without PVAC and DB. The dryer was used to dry ginger to study the kinetics of drying and the quality of the essential oil in each operation mode. In drying tests used a temperature of 60ฐC and a 0.021 kg/s flow rate. The HB drying mode can reduce the drying time by 50%. It also consumes less energy (56% based on electrical energy compared to a HA operating mode) and also gave better results over HA-IR drying. In quality, under a different drying mode, the results were similar in quality with respect to physical appearance, (color, texture etc) but there is a significant variation in volatile oils. The effective variations of main pungent principles in compounds depend on drying time at a constant drying temperature. Finally, based on the drying rate, specific energy consumption and quality of product of all tested process, the HB drying mode was suggested.
