22.03.2021 Temperature and vibration management system

Bühler (see above) has introduced TVM, an innovative Temperature and Vibration Management system for milling. The system is connected to the Bühler Insights platform and provides essential information on the grinding process based on the company’s proprietary algorithms. TVM detects critical operational conditions early to allow timely action to be taken. Precise settings reduce energy consumption and product wastage. The launch of TVM represents another significant step towards thefully digitalised andautomated SmartMill.

The new technology monitors temperature and vibrations inside the grinding rolls, the most important part of machinery in the milling process. To maintain quality and consistency it is essential to apply the same pressure along the rolls. Any deviation results in reduced quality and consistency of the flour. Up to now millers relied on trained personnel to manually check the rollers on a frequent basis and time-consuming laboratory analysis to prevent any deviation from acceptable operative parameters.

The system consists of wireless sensors placed inside the rollers that connect to the Bühler IoT sensing device. It acts as the interface to the Bühler Insights gateway, which transfers data to the Insights platformfor analysis. Temperature and vibration are measured at multiple points along the entire length of the rollers showing the temperature distribution and vibration patterns. This provides millers with detailed information on temperature imbalances side to side and middle to side and detects overheating. The process can be monitored remotely via a user-friendly interface on any device.


With TVM in place it is much easier to ensure that all parameters are set correctly; digitalisation and automation of the plant represents a major simplification of processes and reduces maintenance times
