Device for treatment by pulsed electrical field of a product

The invention relates to a processing device (1) by pulsed electrical field of a product intended to flow through this device, comprising a first and a second electrodes (4, 6) forming parallel plates between which is defined a treatment zone (2), and further comprising a pulse generator (22) electrically connected to said first electrode (4) so ​​as to apply a pulsed electric field in the treatment zone (2), the device also comprising a conduit (26 ) for feeding the product into the treatment zone as well as a conduit (30) discharge. According to the invention, the first electrode (4) is electrically connected to the pulse generator (22) via one of the two conduits (26, 30) arranged in contact with said first electrode.
