Hygienic sensors for milk and dairy processing

The critical control point for successful pasteurization control is temperature. Accuracy and response time ensure that no energy is wasted and the product is not exposed to more thermal stress than necessary.

Endress+Hauser has invented the fastest temperature sensor for hygienic processes. This innovative technology helps you to improve quality and reduce cost. Furthermore, the combination of precise, fast and stable temperature measurement delivers the highest degree of process quality and reliable product quality.

• Improve your temperature monitoring in UHT processing with temperature sensor iTHERM ModuLine TM411.
• Benefit from the shortest response times (t90 = 0.75 s) in the market thanks to the optional available technology iTHERM QuickSens.
• Take advantage from significant time savings during recalibration (up to 20 minutes per measuring point) with iTHERM QuickNeck.
• Reduce risk and improve process safety in critical applications with the self-calibrating compact thermometer iTHERM TrustSens TM371, featuring two fixed calibration points (118°C and 39°C).
• Enable fast, standardized skid integration using compact thermometer iTHERM CompactLine TM311 with IO-Link.

Accurate flowmeters ensure the right amount of heat is applied to achieve safe results.

Electromagnetic flowmeters carry the main burden of flow measurement in dairy operations and play a critical role in milk heating.

• Benefit from integrated temperature and conductivity measurement of Proline Promag H 100.
• Easy integration into your plant infrastructure with IO-link using Proline Promag H 10.
• Benefit from 0 x DN inlet run with constant accuracy independent of flow profile - offered for our electromagnetic flowmeters.
• Heartbeat Technology combines diagnostic, verification and monitoring functions for process optimizations.

One of the more challenging applications in thermal processing systems is the level control of the balance tank. The small tank sees rapid level and temperature changes.

Hydrostatic level sensors are ideal for this application. Temperature compensated and with ranges down to 100mm H₂O, they set the standard for reliability.

• Use Deltapilot FMB50 which also help you to reduce risk in the often harsh environment and cleaning cycles.
• Alternatively, the hygienic compact radar sensor Micropilot FMR43, point level switch Liquiphant FTL43 or pressure sensor Cerabar PMP43 can be used for level monitoring.

To ensure food safety, the differential pressure across the regeneration stage must be maintained. Stability and trust in measurement is key.

For this critical application, a differential pressure measurement is recommended. Optimize your measurement using two compact pressure transmitter Cerabar PMP43.

The microbiological stability of dairy products is crucial for their shelf life and quality, which is often regulated by law. However, heating milk can also lead to buildup on the inner walls. This buildup affects the efficiency of the heating cycle and is a potential cause of product contamination. Therefore, controlling the fouling behavior throughout the heating process and the presence of product in the holding tube is key to process control and optimization of product quality.

Our compact point level devices Liquiphant FTL43 and Liquipoint FTW33 can detect process anomalies such as fouling or buildup. Installed in the holding tube of the pasteurization process, it can continuously monitor the formation and degree of buildup. This helps to decide if a cleaning process is necessary or if the production time can still be extended without affecting the product quality.

All critical process parameters in milk heating must be continuously recorded and maintained. Incomplete, unsecured or inconsistent recordings lead to an increase in non-conformities during audits, a higher workload when addressing deviations, and an increased regulatory risk.

Optimize your management with our data manager Memograph RSG45, which clearly visualize and securely store the recorded process value while ensuring FDA 21 CFR part 11-compliant access control.

Regular maintenance and calibration ensures that the measuring instruments controlling critical processes remain in spec, which is essential to safeguard food safety and quality.
