Energy Aspects in Electrohydrodynamic Drying

Abstract

Acknowledging favorable quality of products obtained through electrohydrodynamic (EHD) drying, there is a lack of knowledge about energy aspects of this promising, yet not commercialized, technology. This article is a critical review of EHD research, which may be crucial for future studies and industrial applications. In particular, effects of electrodes configuration and operating parameters on drying kinetics, energy consumption, and energy efficiency of EHD as compared to conventional drying are examined. Some engineering considerations for using EHD in industrial dryers are also discussed.
