Automatic Milk Measurement and Sampling System

The milk from the milk producers’ societies at the bulk milk cooling center is collected by the milk union through road milk tankers. Often, disputes arise between the milk producers’ society and the milk processing union regarding the quantity of milk and the fat and SNF content, as the quantity measurement is typically done using a dip stick in the bulk milk cooler.

To eliminate these disputes, IDMC has developed an automatic milk measurement and sampling system, which is mounted behind the road milk tanker. This fully automatic unit is available with either 6 or 14 sampling bottles, allowing collection from 6 or 14 milk producers’ societies.

Key Features:

• The milk transferred from the bulk milk cooler is measured through an automatic milk flow meter, with quantity recorded via PLC.
• A peristaltic pump draws a proportionate inline sample while transferring milk into the tanker.
• Samples are collected randomly in bottles equipped with RFID tags, ensuring secure and tamper-proof tracking.
• A composite sample is drawn into one bottle to represent all 6 or 14 societies.
• A cooling pad is integrated to maintain low sample temperatures and prevent spoilage.

When the tanker arrives at the dairy plant, PLC data is transferred to the server. The QC in charge at the milk processing union collects the sample bottles and decodes them using an RFID card reader. The recorded milk quantity is retrieved from the PLC, and the fat and SNF content is analyzed from the collected sample.
