Data loggers record essential environmental information to help identify potential problems in the dryer, to ensure quality levels are maintained.
Wienerberger is the world's largest manufacturer of bricks,
operating a total of 214 plants in 30 countries. Wienerberger is
the second largest brick manufacturer in the UK with a number of
At the company's Denton factory near Manchester, Tinytag temperature and
relative humidity loggers are being used to measure any
potential anomalies in each of the tracks within the brick dryer,
in relation to balance of temperature compared with humidity
levels. This is very important as 'dryer dripping' can occur during
the process, causing water droplets to make impressions on the
bricks, which affects the overall quality of the yield.
If dryer dripping occurs, the loggers are placed on a dryer car
and sent through the tracks in question. The data helps identify at
what point the humidity is high (which usually shows a drop in
temperature), pinpointing at what stage this occurs in the dryer.
Investigations can then be made to see if there is a problem with a
certain fan down the track: if a fan is found to be faulty, the
relevant repairs or adjustments can be made to rectify the
Production and Maintenance Controller Michael Stewart is
responsible for purchasing all critical and consumable spares along
with producing performance data analysis systems. Michael comments,
"The Tinytags were sourced by our Deputy Works Manager who also
manages the Kiln, which directly relates to the dryers as the
residual hot air is taken over to them from the Kiln."
The image shows the dryer entrance: the gaps that are visible in
between the cars are closed off by the first rotational fan and
every fan after that down the tracks. Michael adds, "We are very
satisfied with the Tinytags as we were able to work out exactly
where we were experiencing issues within the dryer. These areas are
inaccessible when all the tracks are laden with bricks so it helped
us out a great deal."
