[0039] Preferably, the adjusting slider 400 of the bracket unit 100 can be installed on the side plates 510 of the airing equipment located on both sides of the airing chain plate 500. In other words, the bracket unit 100 can include two adjusting sliders 400. Preferably, the adjusting slider 400 can be welded to the side plates 510 of the airing equipment.

[0040] Preferably, the support body 110 of the support unit 100 can pass through the channel in the corresponding adjustment slider 400 through the support rod 120, so that the adjustment slider 400 can limit the moving direction of the support body 110. Preferably, the adjustment slider 400 can be equipped with a limiter 410, wherein when the limiter 410 moves out of the channel in the adjustment slider 400, the support rod 120 can move freely in the channel of the adjustment slider 400 along the opening direction of the channel; when the limiter 410 enters the channel in the adjustment slider 400 and abuts against the support rod 120, the movement of the support rod 120 is limited. Optionally, the limiter 410 can be selected as a screw, a bolt or the like. Such a setting allows the cross-height of the support body 110 relative to the airing chain plate 500 to be flexibly adjusted, thereby meeting the requirements of different types of mash for airing thickness.

[0041] Preferably, the base member configured for the bracket body 110 may include a first base member 111 connected to the support rod 120, and a second base member 112 and a third base member 113 respectively disposed on both sides of the first base member 111.

Further, the scraper adjustment member 220 may be fixedly installed on the second base member 112, or may be movable on the second base member 112 to adjust the setting position of the scraper unit 200.

[0045] Such an arrangement can realize the temperature measurement of the bottom mash at different plane positions on the airing chain plate 500 or the temperature measurement of the bottom mash at multiple plane positions on the airing chain plate 500 at the same time. And because the scraper plate 210 can adjust the probing depth through the scraper adjusting member 220, when completing the above temperature measurement operation, the scraper plate 210 can be adjusted to a suitable position according to the actual temperature measurement needs, so as to expose the bottom mash at different depths.
