Inline quality control in your food production

Inline quality control in your food production

Ensure product quality, avoid product loss and increase plant availability

Pressure on sales, margins and product quality, combined with a shortage of skilled labor, drive food processors to look at more efficient ways to increase productivity uptime and reduce product losses. By supplementing or replacing laboratory measurement with inline measurement instrumentation, production check steps can be greatly improved, thus increasing throughput and reducing hold times as well as the risk of off-spec product.

  • < 1%

    waste

    This is what all food manufacturers worldwide are aiming for. But it is often far higher, 5% and more are not uncommon. Waste occurs in food manufacturing for a variety of reasons: Production changeovers, recipe errors, or production delays that lead to raw material degradation and variability.
    The introduction of inline quality measurements helps to improve or even eliminate some of these circumstances, ensuring quality and further reducing waste.

Our Offering

Inline quality measurement enables processes to run with a higher level of control. Changes in the process, caused by raw materials, energy supply or operational influences, can be detected immediately. Inline quality control tracks the process every second to complement lab testing, completing the picture and facilitating continuous quality improvements. Endress+Hauser offers a wide portfolio of technologies and process instrumentation that help you:

  • Ensure product quality and protect your brand

  • Avoid product losses

  • Increase plant availability

  • Reduce raw material

Applications

pH measurement

More than 30% of all quality-relevant process measurements are related to pH. While this parameter is often used to monitor taste and consistency, the primary application is to ensure the correct pH levels in acidified foods for safety purposes.

Inline ph measurement
Our expertise in the field

Other examples include: monitoring the fermentation rate or determining when fermentation is complete, detecting trace CIP fluid contamination before packaging or bottling, monitoring the pH value to ensure the shelf life of the end product. Endress+Hauser offers a wide range of pH sensors, from glass electrodes and enamel sensor up to non-glass ISFET sensors.

  • Rely on glass sensors like the Memosens CPS61E for precise measurements and rapidly changing pH values.

  • For very sticky or viscous media such as mayonnaise, the Ceramax CPS341D enamel sensor meets the highest demands for measurement accuracy while providing optimal long-term stability and the lowest maintenance requirements.

  • The Memosens CPS77E non-glass ISFET sensor can be used with peace of mind for final pH checks or in production.

Density and concentration measurement

To monitor and control the consistent quality of a product, density must be measured accurately. To determine the concentration, the density values are converted to different units such as Brix, Baume, API, Plato or alcohol.

Monitor and control medium condition inline
Our expertise in the field

The medium density can be continually (inline) monitored and controlled in a wide range of applications, drastically reducing the effort involved in regular sampling and lab analyses. Endress+Hauser offers different physical measuring principles.

  • Measure density/concentration with superior accuracy using the Proline Promass Q 300. This flowmeter is optimized for liquid applications where entrained gas is known to be present.

  • Vibronic technology offers accurate density measurement in tanks. Hygienic design and cost-effective installation with up to 5 measuring points managed by a single FML621 density computer.

Color and turbidity measurement

Color and turbidity measurement are essential for quality and taste in edible oil, beverages, beer, wine and molasses. They are use in a wide variety of applications such as effluent monitoring, removing turbid substances in raw oil, product loss detection in dairies or simple phase separation.

Food production needs close monitoring of color and turbidity
Our expertise in the field

Ensuring each of these applications and processes requires permanent monitoring of the critical parameters color and turbidity. Endress+Hauser offers a wide range of optical sensors dedicated to the specific application need.

  • Precise inline color measurement in liquids in the visible region of the electromagnetic spectrum using our OUSAF22 color sensor, which measures the slightest color changes to ensure superior end product quality.

  • The OUSTF10 inline turbidity sensor is used for measuring suspended solids, emulsions and immiscible fluids in process liquids.

  • The OUSAF11 hygienic absorption sensor is used for phase separation or for ensuring that the right grade of milk is present. Also suitable for the immediate detection of product in CIP solutions and effluent or media leaking into chiller water lines.

Conductivity measurement

Conductivity measurement can provide early detection of contamination from improperly flushed lines or leaking valves. This facilitates early identification of the source of the issue and prevents contaminated products.

Installed sensor for inline quality measurement
Our expertise in the field

Endress+Hauser provides reliable and accurate instruments for all measurement ranges and conditions, such as CIP cycles or hygienic processes. Benefit from a wide range of sensors and transmitters.

  • Where speed of response or highest accuracy is needed, the Indumax CLS54D digital conductivity sensor is unmatched in the market.

  • Choose the compact conductivity device Smartec CLD18 for applications where the toroidal measurement is needed and an embedded transmitter is of advantage.

  • Use the Memosens CLS82E digital 4-electrode conductivity sensor for hygienic applications that need to cover a broad measuring range such as phase separation or fermentation.

Chemical composition measurement: Raman spectroscopy

Inline Raman spectroscopy measurements provide in-depth chemical composition knowledge about your process without the need to collect a sample for laboratory analysis. Raman spectroscopy can monitor multiple aspects of product quality with a single probe, around the clock, thus enabling in-process corrections and faster product release.

Measure chemical composition with Raman spectroscopy
Our expertise in the field

Incorporation of Process Analytical Technology (PAT) tools, such as Raman spectroscopy, into the process during early stages of process development helps deliver consistent product and process quality. With our proven reliability, repeatability, and compliance support, we have over 30 years of customer success in process improvements after implementing Kaiser Raman technology.
