Abstract
System for treating pumpable products by electrical pulses comprising at least one treatment chamber formed by at least two modules and comprising a flow channel through which product can be pumped, an end electrode at the one end of the treatment chamber to which a low voltage has to be applied, another end electrode at the other end of the chamber to which a high voltage has to be applied, a generator circuit for generating voltage pulses to be applied to said electrodes. The treatment chamber is provided with at least one intermediate electrode which is located in between the end electrodes and to which a voltage in between the voltages of the two end electrodes has to be applied.
Claims3
Apparatus for treating pumpable products by electrical pulses, comprising:
- at least one treatment chamber formed by at least two modules, and having a first end and an opposite second end, and a flow channel extending between said ends for pumping a product therethrough;
- a first end electrode at said first end, and means for applying a first voltage to said first end electrode;
- a second end electrode at said second end, and means for applying a second voltage to said second end electrode, said first voltage being lower than said second voltage;
- a generator circuit for generating voltage pulses to be applied to said electrode;
- and
- at least one intermediate electrode positioned between said end electrodes, and means for applying a third voltage to said intermediate electrode, said third voltage having a level between said first voltage and said second voltage.
