Claim Text:
1. A method for pasteurizing a continuous product chain in a device comprising an inlet, a heat-up region divided into treatment zones, a pasteurization region divided into treatment zones, a cooling region divided into treatment zones, an outlet, and transport means for passing products through said heat-up region, then through said pasteurization region, and then through said cooling region from said inlet to said outlet of said device, said method comprising heating up, pasteurizing, and cooling by heat transfer between said products and a spray medium with which said products are sprayed, wherein heating up, pasteurizing, and cooling comprises, for each of said treatment zones, adapting a temperature of said spray medium at said treatment zone to cause a desired consequence to heat transfer in said treatment zone, and varying a pasteurization process by changing a volumetric flow rate of said spray medium in said treatment zone between a maximum value and a minimum value, whereby each treatment zone has a volumetric flow rate that is able to be varied in time independently of volumetric flow rates in other treatment zones.
