Ultrasonic milk analyser
4. CLEANING THE ANALYZER
This procedure prevents gathering milk fat residues and milk stone on the
sensor. The milk stone consists of milk solids, calcium, iron, sulphates,
magnesium, etc. All these substances form layer on the pipe and sensor’s
walls, which leads to deviations in the measurement results and blocking up
the piping.
The company-producer recommends usage of the chemicals, supplied with
the analyser – alkaline and acidic (Lactodaily and Lactoweekly). You may
order them separately or together with the analyser. Try to use only these
chemicals for cleaning the analyser.
4.1. Automatic cleaning the analyzer
Analyzer's contamination as a result of the irregular cleaning is the basic
reason for inexactness during measurement. In order to be avoid this, in the
milk analyzers with peristaltic pump is embedded automatic cleaning. For this
purpose the analyzer has to be prepared on the following way:

Please, pay attention to the additional pipe, connected towards the input pipe.
It has to be long enough to suck all the content in the glass, but to be bent in
order not to impede the pump function.
