ENSURE YOUR WASH SYSTEM DOESN’T LEAVE YOU IN THE COLD
By Rick Bosma
A
clean milk pipeline is important for
delivering high-quality milk to processors. However, you may not always have time to grab a thermometer and
stopwatch each time you do a pipe wash
to ensure the water is warm enough and it
stays that way long enough.
While you may see steam rising off the
sink filling with washwater on a cold winter
day, you can’t assume it will stay that way as
it makes its way around the barn. It is also
a good idea to check your bulk tank’s temperature during a wash. These tank washes
can take more than an hour. Fortunately,
you have a Time Temperature Recorder
(TTR) to check these temperatures at every
wash, every day, all year long.
While useful, there may be times when
your TTR sounds an alarm and all you
want to do is get on with your day and not
be interrupted by the shrill howl of that
box on the wall to remind you something
has gone wrong. It’s easy enough to punch
the button to silence the alarm and keep
moving. However, it is likely trying to tell
you what went wrong.
TTRs in Ontario are generally setup to
generate an alarm if a pipe wash does not
reach at least 40C. Some of you are aware
of the 40C requirement and may have been
wondering why this number was chosen.
When TTRs were introduced, many of
the soaps or detergents recommended the
water used for the wash be above that temperature. This was to ensure a clean pipeline after the wash. Most detergents recom-

mend this temperature be maintained for
a certain amount of time so the chemicals
have enough time to do their job. This
is the reason the TTR will tell you even
though the temperature went over 40C, it
did not see the temperature stay over that
level long enough. By default, most systems
