Kinetic characteristics and energy efficiency analysis of microwave-dried fresh ginger: Impacts of key process parameters

Microwave drying has emerged as an energy-efficient and environmentally benign alternative to conventional methods. Given the considerable nutritional and medicinal value of ginger, this study systematically investigates the effects of key parameters, such as microwave power (600–1800 W), slice thickness (1–7 mm), and loading amount (200–500 g), on drying kinetics and energy consumption of microwave-dried ginger. The mechanisms of key parameters on moisture migration and energy changes are discussed. The results reveal that the Page model best characterizes power-dependent drying, while the Midilli model better fits loading and thickness variations. Increasing microwave power considerably increases moisture…
