Analyzer provides in-line concentration measurement for food and beverage production
Mike EdwardsProducts Endress+Hauser food and beverage
The Endress+Hauser in-line Teqwave H analyzer is said to enable users to reliably monitor fluids in the food and beverage industry. A range of applications are possible, such as monitoring sugar content in fruit juices and distilled beverages or the concentration of cleaning agents.
The hygienic design of the analyzer is also said to fulfill the highest quality standards with state-of-the-art algorithms and a flexible application concept guarantee optimal process control even when changing batches.
In soft drink and fruit juice production, the measuring device assures product quality through its reliable determination of sugar content and invert sugar content. For production of distilled beverages, it ensures that the alcohol content remains consistent. In addition, it simultaneously measures the sugar content.
When cleaning plants, bottles and kegs, the Teqwave H analyzer also monitors different concentrations and it supports precise dosing of cleaning agents. If the cleaning agent needs to be changed, this can be done easily without recalibration.
The analyzer has been developed for such hygienic applications. A particularly noteworthy feature, in addition to the stainless-steel measuring tube, is its full-bore design. With no protruding parts, there are no places inside the measuring tube where material can accumulate. Another benefit is that there is no pressure loss, making it possible to save on energy costs.
The unit can measure different concentrations at the same time using only one sensor, another potential cost saver for operators. Concentration datasets are preinstalled for the most common beverages and cleaning agents, making it possible to use the same sensor with no reprogramming and without any problems, even for batch changes. It’s possible to read in additional parameters, such as acid content. Teqwave H uses these to calculate the concentration with even greater accuracy thanks to its state-of-the-art algorithms. Continuous in-line measurement also means no sampling is required.
Dispersion measurement is another product advantage. The common appearance of disturbance variables such as particles and gas bubbles is no longer a problem, since the unit measures, displays and compensates for these disturbances and their severity directly. The analyzer enables users to detect such disturbance variables, evaluate their severity and compensate for them to achieve continuous accurate measurement. The device warns the user when the disturbance variables affect measuring accuracy. This guarantees maximum reliability and provides users with even greater transparency in their processes.
The analyzer simultaneously records multiple measured values that are essential for process control, such as concentrations, speed of sound, acoustic density, and temperature in many different fluids, and then forwards them to the process control systems. Access to measurement data is possible at any time — by using conventional 4 to 20 mA or with digital data transmission via Modbus TCP.
The Teqwave H offers a wide variety of preinstalled, product-specific data sets for concentration measurement, which allow the user to omit the usual calibration after batch change. The users can adapt these data sets to their product as needed to further increase the accuracy of concentration measurements. Users with a wide product range need just one measuring device for a broad range of applications. This is particularly helpful when one production line is being used to manufacture the entire product range in various batches.
