Efficient Process Control thorugh process analytics: Make your quality measurable with analytical sensors

Many production and CIP processes are based on differentiating media through qualitative characteristics such as turbidity, conductivity, or concentration. Deviations in these criteria are critical for the quality of the product, and for the efficiency of the process. However, these deviations are not easily detectable.

Manual sampling is one method used for control, but this means high personnel costs and uncertainties in the quality between samples.

Time control is another option; however, a safety buffer must be considered. As a result, each phase transition leads to product loss and high costs for wastewater treatment, as many liters of valuable product or cleaning agent end up in the sewer during this buffer time.

They see what you can’t: Making quality visible with analytical sensors

We invite you to “EXPERIENCE THE DIFFERENCE” with Anderson-Negele. Our analytical sensors provide a solution to exactly this issue. As your “eye in the pipe” they continuously measure the media in the running process according to qualitative criteria, thereby making the invisible visible and quality measurable.

Versatile application for improved efficiency and quality

Field cases show that Anderson-Negele analytical sensors often have a payback period of only a few weeks due to the reduction of costs, product losses and wastewater, and thanks to an improved compliance with quality criteria. Here are just a few examples:

• CIP Control: By phase separation with an accuracy to the second in CIP control with the ILM-4 conductivity meter, water consumption can be reduced extremely significantly. In a practical case at a manufacturer of ice cream, the saving was 175,000 liters per year

• UHT Phase Transition: Detecting loss of valuable organic milk in the UHT plant, a dairy installed ITM-51 turbidimeters to replace the previous timer-based control. The result: 118 fewer liters of product are lost with each phase transition (proven by measurement).

• Separator Control: In a brewery, the ITM-51 turbidity sensor continuously monitors the output of the separator. The desired turbidity level was entered by means of an individual learning curve at the installed sensor. When the predefined setpoint values are reached, the yeast harvest is carried out in an automatic, accurate, and reproducible way.

• Filtrate Monitoring: In wine production, the integrity of the filter membrane used to be monitored through a sight glass. This was very time consuming and inaccurate. Thanks to its high measuring accuracy even at the lowest turbidity levels, the ITM-4 turbidity meter is ideal for quality assurance to avoid secondary fermentation and quality degradation due to filter damage.

• Bottling / Filling Control: With a response time of just under one second, the ILM-4 conductivity sensor can detect a phase switch with high accuracy and precisely control the corresponding valve via an active switching output. In a brewery, in filling systems for bottles, cans, and kegs, one conductivity meter each ensures that the beer ends up in the bottle and rinse water in the sewer.
