Wine Clarification with Turbidity Measurement
15 Sep 2020
For the wine consumer, the first quality characteristic, even before the smell and taste, is the visual experience. In addition to color, the clarity of the wine is particularly important. To achieve this quality, a California-based winery installed Anderson-Negele’s ITM-4 to monitor turbidity in their clarification process before bottling.
Anderson-Negele helped the customer improve its processes in both applications, increase production yields, and consistently monitor product quality specifications.
Centrifuge Drum Purge control: In the centrifuge application, when the drum bowl begins to reach the fill level, wine turbidity at the discharge of the centrifuge will start to rise. The ITM-4 easily detects this increase in turbidity. With a range of 0 to 5000 NTU, the ITM-4 4–20 mA signal can be scaled to accurately measure product turbidity and signal the PLC when process turbidity setpoints are reached.

Cross-Flow Filtration Monitoring: The ITM-4 turbidity meter continuously monitors wine filter retentate before the packaging stage. With range settings from 0 to 5000 NTU, the ITM-4 is ideal for low turbidity measurement.
The ITM-4, with its process automation, could eliminate the traditional method of periodically checking the filters, which was very time-consuming.
