A method for pasteurizing a continuous product chain in a device having an inlet, heat-up, pasteurization, and cooling regions all divided into treatment zones, and a transporter for passing products through these regions includes heating up, pasteurizing, and cooling by heat transfer between the products and a spray medium with which the products are sprayed, for each of the treatment zones, adapting a temperature of the spray medium to cause a desired consequence to heat transfer in the treatment zone, and varying a pasteurization process by changing a volumetric flow rate of the spray medium in at least one treatment zone between a maximum value and a minimum value. |

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. |
