Ohmic heating system contains at least two or more electrodes to impart current upon the fluid, electrode especially is a critical factor when designing ohmic heating equipment, there are different designs depends on the electrodes locations and positions, the design can be set up either as static systems in container vessel or with continuous flow through them [19].
Basically, there are two widely design of ohmic heating system, open geometry which makes clearing easier and reduce the effect of fouling and prevents damage to products [22]
