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. 2. The method of claim 1, wherein adapting a temperature of said spray medium comprises changing said temperature of said spray medium. 3. The method of claim 1, further comprising changing a rate at which said transport means passes said products. 4. The method of claim 2, wherein varying said pasteurization process further comprises changing a rate at which said transport means passes said products. 5. The method of claim 1, further comprising selecting one or more volumetric flow rates of said spray medium based at least in part on a type of container whose contents are to be pasteurized. 6. The method of claim 1, further comprising, based at least in part on a determination that, in at least one treatment zone, a volumetric flow rate of said spray medium is at or above a predetermined volumetric flow rate, reducing, in said at least one treatment zone, a volumetric flow rate of said spray medium to be below said predetermined volumetric flow rate of said spray medium at said at least one treatment zone. 7. The method of claim 1, further comprising, based at least in part on a determination that, in at least one treatment zone, a volumetric flow rate of said spray medium is at or below a set volumetric flow rate, increasing, in said at least one treatment zone, a volumetric flow rate of said spray medium to be above a set volumetric flow rate of said spray medium at said at least one treatment zone. 8. The method of claim 1, further comprising reducing a volumetric flow rate of said spray medium and increasing a time span during which said container to be pasteurized is exposed to said spray medium thereby achieving a selected temperature change of said container. 9. The method of claim 1, further comprising increasing a volumetric flow rate of said spray medium and reducing a time span during which said container to be pasteurized is exposed to said spray medium thereby achieving a selected temperature change of said container. 10. The method of claim 1, further comprising, based at least in part on an operating condition of said device, reducing, in at least one treatment zone, a volumetric flow rate of said spray medium. 11. The method of claim 1, further comprising, based at least in part on an operating condition of said device, increasing, in at least one treatment zone, a volumetric flow rate of said spray medium. 12. The method of claim 1, further comprising, within a first treatment zone, changing a volumetric flow rate of said spray medium such that, at a first time, said volumetric flow rate of said spray medium within said first treatment zone has a first value, and at a second time that is different from said first time, said volumetric flow rate of said spray medium within said first treatment zone has a second value, wherein said second value is different from said first value, wherein volumetric flow rate within said treatment zone is time-varying, and wherein said first value and said second value are within a closed interval bounded by a maximum value for said first treatment zone and a minimum value for said first treatment zone, said method further comprising, within a second treatment zone, changing a volumetric flow rate of said spray medium such that, at a third time, said volumetric flow rate of said spray medium within said second treatment zone has a third value, and at a fourth time that is different from said third time, said volumetric flow rate of said spray medium within said second treatment zone has a fourth value, wherein said fourth value is different from said third value, wherein volumetric flow rate within said treatment zone is a function of time, wherein said third value and said fourth value are within a closed interval bounded by a maximum value for said second treatment zone and a minimum value for said second treatment zone, wherein changing volumetric flow rate in said first treatment zone is carried out independently of changing volumetric flow rate in said second treatment zone, and wherein said first treatment zone and said second treatment zone are different treatment zones. 13. The method of claim 1, further comprising determining a heat transfer rate between said spray medium and a container containing a product in response to a change in temperature of said spray medium. 14. The method of claim 1, further comprising determining a heat transfer rate between said spray medium and a container containing a product in response to a change in volumetric flow rate of said spray medium from a first non-zero value to a second non-zero value. 15. The method of claim 1, further comprising controlling heat transfer between a container that contains a product and an environment surrounding said container. 16. The method of claim 1, further comprising detecting a break in production, and, in response to detecting said break in production, reducing a volumetric flow rate in at least one treatment zone from a first non-zero value to a second non-zero value. 17. The method of claim 1, further comprising detecting a reduction in container supply rate and, in response, changing a volumetric flow rate in at least one treatment zone from a first non-zero value to a second non-zero value. 18. The method of claim 1, further comprising detecting a resumption following a break in production, and increasing volumetric flow rate in at least one treatment zone from a first non-zero value to a second non-zero value in response to said detection.
