Abstract:
Treatment apparatus for preserving pumpable food products in a pulsed electric field, said apparatus comprising a treatment chamber with an inlet for food products to be treated and an outlet for treated food products, the treatment chamber being provided with a system of electrodes which comprises at least one first electrode and at least one second electrode, as well as an electrical energy source connected to the electrodes 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, wherein the treatment chamber has an effective area of flow having rounded corners and the at least one first electrode and the at least one second electrode of the system of electrodes are disposed in such a way that the field lines of the electric field run parallel to one another and the potential controller is of such design that the electric field in the effective area of flow is uniform.
