ABSTRACT:
Methods and apparatus for electroheating an electrically conducting flowable material are provided. In a preferred embodiment, flowable material is conveyed from an entrance passageway to first and second electrode assemblies. The flowable material is then conveyed from the first and second electrode assemblies to an exit passageway. Voltages of opposite polarity are respectively applied to the first and second electrode assemblies so that a first electric current passes through the flowable material as it is conveyed from the entrance passageway to the first and second electrode assemblies, and a second electric current passes through the flowable material as it is conveyed from the first and second electrode assemblies to the exit passageway, in order to electroheat the flowable material. The flowable material preferably is rapidly cooled after being electroheated. The present invention may, for example, advantageously be used to electroheat biological proteinaceous matter, such as liquid egg or milk.
