Ultrasonic milkanalyser
Operation manual 04.11.09 20/107
There are two ways of cleaning the analyser embedded in it – current and
end (final) cleaning.
4.1.1. Current cleaning.
4.1.1.1. Automatic start
The current cleaning is made with alkaline solution (for working solution
preparation see 4.2.1.), with which the reservoir for the cleaning solution is
filled in.
It is automatically started, without operator's interference after the set time
intevals elapse
1. 55 min. after switching on the power supply of the analyser,
but idle work;
2. 15 min. after the last measurement of real milk sample.
After cleaning a new measurement is started in the above described
intervals.
The display shows the following message and a sound signal is emitted:
Auto clean
started!
Put empty glass
After this the cleaning is started. The display shows:
Cleaning
Please wait
If there is a glass with sample it is completely emptied and then the analyser
automatically fulfills procedure for sucking the cleaning solution and c rinsing
the analyser's inner system. In order the input metal pipe to be cleaned out
for a short time a cleaning solution is pumped out for a short time in the
already empty glass or in case there is no empty glass there – in the funnel
for the waste liquids. It is filled to the middle and then is sucked back and
poured in the reservoir with the used liquids. In case that you are sure that
you’ll not use the analyser for a longer period, but it will be connected to the
power supply and switched on, which means that the process of automatic
clean will be active, do not leave sample holder in the recess of the analyser,
in order not to be overfilled during cleaning from the output pipe. Then the
cleaning solution will be directly poured in the funnel for waste liquids.
