Table 2 The mass transfer enhancement factor and current versus voltage for the EHD drying system at 28 kV of the two types of voltages
From: Electrohydrodynamic (EHD) drying of the Chinese wolfberry fruits
Type of voltage | 28 kV (needles-to-plate DC) | 28 kV (needles-to-plate AC) |
|---|---|---|
Current (μA) | 10 | 369 |
The mass transfer enhancement factor | 1.16033 | 1.96314 |
