Ehd-Enhanced Drying With Wire Electrode

Effect of electrohydrodynamic (EHD) technique on drying process and appearance of okara cake

“…The results reported by Li, Li, and Tatsumi (2000) showed that the drying process of the okara cake exposed to the HEF system directly entered falling rate drying periods and the rate of the EHD drying at the initial drying period was about 2 times higher than that of the control. Lai and Lai (2002) reported that the EHD drying without cross-flow increased the drying rate linearly with applied voltage, but the enhancement in the drying rate was nearly independent of the applied voltage with a cross-flow. In addition to the point-to-plate HEF system used to promote drying rate, Carlon and Latham (1992) performed an experiment with an even electric field, which consisted of two smoothed circler copper electrodes, under the different electric field intensities.…”

Electrohydrodynamic drying of apple slices: Energy and quality aspects

“…Since hot air drying is the only option commercially available, industry expressed interest in the development of efficient non-thermal technology. One of the potential candidates is electrohydrodynamic (EHD) technology, which applies high voltage to enhance single-phase convective heat and mass transfer (Lai and Lai, 2002). Previous research showed advantages of EHD technology for drying of biological materials, such as potato, apple, tomato, mushroom slices, spinach, rapeseed, wheat, okara cake (Singh et al, 2012).…”

The Onset of Darcy–Brinkman Electroconvection in a Dielectric Fluid Saturated Porous Layer

“…Therefore, new techniques are being used to make the drying processes more efficient and one of the effective ways to improve the overall drying kinetics is to apply an electric field (Yabe et al 1996;Lai and Lai 2002). It is thus imperative to study the onset of ETC in a layer of porous medium.…”
