  • Treatment apparatus and method for preserving pumpable food products in a pulsed electric field
    Publication number: 20020170439
    Abstract: An apparatus for preserving food products in a pulsed electric field comprises a treatment chamber having an inlet for food products to be treated and an outlet fortreated food products and has an effective area of flow having rounded corners. The treatment chamber further comprises at least one first electrode and at least one second electrode which are disposed in such a way that the field lines of the electric field run parallel to one another, as well as an energy source and a potential controller to control the potential on at least one first electrode and on at least one second electrode in order to generate a pulsed electric field, of such design that the electric field in the effective area of flow is constant. In a method for preserving food products in a pulsed electric field, the direction of said pulsed electric field in successive pulses is rotated through 90°.
