What Is Preventing Electrohydrodynamic Drying Technology From Being Applied Industrially, And What Can We Do About It?

Electrohydrodynamic (EHD) drying is basically a highly efficient way to convectively dry materials. Its unique trait is that airflow is produced locally by corona discharge instead of mechanically by a fan. As such, there are no moving parts nor fan blades. In order to achieve this, a high voltage difference – several thousands of Volts –
