Description of the Prior Art In dry heat sterilization of containers such as glass bottles and ampoules for drugs outside the intestinal tract, it is most important that all containers in the sterilizer are heated to a prescribed target temperature. is there. To monitor the sterilization temperature,
In the sterilizer known from EP-A-3122022, the temperature of the container is measured in the sterilization zone by means of a radiation pyrometer, after which the transport of the container through the furnace is controlled. In order to protect the pyrometer from large heating effects and to ensure unobstructed view of a relatively large area, the pyrometer is mounted in the side wall of the furnace and therefore the vessel in the examination area is It is detected from above at a relatively flat angle perpendicular to the transport direction of the container. Since the vessels through the furnace are generally guided alongside one another in abutting relation, only the respective upper areas of the vessels are accessible to the temperature inspection section. As a result, in such inspections, the upper range of the container within the detection area will in total present a representative measurement. Moreover, the known device also does not guarantee that the container body and the container bottom reach the minimum temperature required for sterilization.

とができる。A thermal radiation measuring device 25 is arranged above the through hole 18 in the front wall 13 to check whether the container 1 conveyed through the furnace 10 is heated to the required sterilization temperature. The thermal radiation measuring device is directed through the opening 26 in the front wall 13 into the upper chamber part of the furnace 10 parallel to the transport area of the transport belt 17. In the “line-of-sight” direction of the thermal radiation measuring instrument 25, the upper part I of the upper part of the chamber of the furnace 10
Arranged above the plane of the R-radiator 21 are a plurality of flat strip-shaped mirrors 30 suitable for said IR-radiator. The mirror surface of the plane mirror 30 is inclined towards the thermal radiation measuring device 25 and towards the transport area of the transport belt 17, so that the thermal radiation emitted upwards from the container 1 standing on the transport belt 17 is: It is deflected by approximately 90 ° with respect to the receiving member of the thermal radiation measuring instrument 25. In order to capture all areas in the furnace 10, the individual mirrors 30 are arranged offset in the transport direction and the height direction of the transport belt 17, so that the mirrors are
It overlaps with the intermediate space between the upper IR-emitters 21 and forms a closed projection plane in the height direction. By defining and arranging a plurality of mirrors in the furnace, it is possible to detect the temperature distribution of the container 1 in the entire furnace by only one thermal radiation measuring device. However, it is fundamentally sufficient to arrange individual mirrors in the end region of the furnace in which the vessel 1 reaches a predetermined maximum temperature, by observing a narrow area which extends over the entire width of the conveying device. You can

A D-diverting unit or a 2D-diverting unit can be provided. An IR-camera is very well suited, by means of which the temperature can be defined on the basis of the known emissivity of glass. The IR-camera is able to detect the IR-radiation reflected by the mirror from the defined detection surface line by line and one by one, so that by means of a suitable calculation or image processing program the detected temperature signal is prepared. Moreover, it has the advantage that a plurality of measuring points can be arranged between the containers 1, such as the rim of the container 1, the shoulder or bottom and the surface of the conveyor belt 17.

In particular, the lowest measured temperature is used for power control regardless of where the temperature was measured. This eliminates the need to search for a suitable reflection measuring point, that is to say that the reflection measuring point can be adjusted at different locations in the furnace in vessels of different sizes and thus in different convection conditions. It is also possible for the mirror, which is fixedly placed in the furnace, to be varied so that it can be swiveled around the longitudinal axis of the mirror or can be moved together with the container 1 over a defined section. Thus, by traveling synchronously with the containers, monitoring of these containers is possible for a defined time.
