Abstract
An electroheating apparatus to continuously treating pumpable food is made up of a number of connected electroheating cells. In one embodiment, all of the cells include a pair of concentric electrodes between which the food is pumped. The electrodes are connected to a high frequency energy source which passes current through the food to heat them based upon their own resistivity and the electrode gap. In another embodiment, two different functioning electrodes are used, connected in series, so as to provide long run times and high process temperatures.
Claims35
An apparatus for electroheating food comprising:
- at least one first electroheating cell having a first pair of electrodes separated by a first gap through which food can flow;
- at least one second electroheating cell having a second pair of electrodes separated by a second gap through which food can flow and in fluid communication with said first gap;
- and a source of AC electric current having a frequency which is effective to electroheat said food without electrolysis operably linked to said at least one first and said at least one second electroheating cells, said source of AC electric current applying a relatively high voltage, relatively low current, high frequency AC electric current across said first pair of electrodes, and said source of AC electric current applying a relatively low voltage, relatively high current, high frequency AC electric current across said second pair of electrodes.
