Abstract
An electroconductive heater for heating a liquid product such as a liquid whole egg product which has a conductivity which increases with temperature, is disclosed. The electroconductive heater comprises an enclosed chamber defining a liquid product flow space, the enclosed chamber having an upstream end portion, a downstream end portion, and first and second electrically conductive plates positioned opposite one another in spaced relationship with the liquid product flow space therebetween. The first and second electrically conductive plates longitudinally extend from the upstream end portion to the downstream end portion. The chamber has a characteristic resistivity of the electrical pathway between the first electrically conductive plate and the second electrically conductive plate which is greater in the downstream end portion than in the upstream end portion. Apparatus and methods of using such electroconductive heaters are also disclosed.
