1.1 Inline measurement of protein, fat and lactose in milk products

The innovative OPTIQUAD-M 4050 WOPTIQUAD-M 4050 WOPTIQUAD-M 4050 WOPTIQUAD-M 4050 W is used to measure the protein, fat and lactose in milk products and opens up new possibilities in process optimization.

Unlike conventional bypass devices, measurement takes place directly in the pipeline - without coming into contact with the medium. Analysis is done through an optical window in a standard VARINLINE® measuring section. This enables the OPTIQUAD to provide extremely precise readings every second, enabling much quicker intervention into production.

The advantages are obvious: Measurement is hygienic and there is no need for sampling or sample transport and its associated sources of error. High long-term stability and no need for consumables mean a significant reduction in operating and maintenance costs. Best of all, the OPTIQUAD outshines typical bypass devices with its outstanding price/performance ratio.

Highlights• Inline measurement of protein, fat and lactose in milk products• Non-contact analysis• High precision and long-term stability• For use in dynamic control loops• Eliminates the need for sampling, sample transport and preparation• Eliminates the need for daily cleaning• No costs for chemicals, reagents and cleaning agents• Impressive price/performance ratio

Industries• Dairies• Cheese dairies

Applications• Strategic increase in the protein content of cheese-making milk by adding protein

concentrate as retentate from a UF plant.• Standardization of the fat content in drinking milk production.• Setting a constant ratio of fat to protein. This results in a constant quantity of cheese per

cheese producer, and the avoidance of empty forms in the press system. The increase in the protein content from 0.1% to 0.3%, depending on the type of cheese, results in an increase in yield of 2% to 5%!

• Increased concentration of whey or skim milk to produce protein concentrate.• Production of protein concentrate through evaporation and spray drying.• Measurement and setting of the fat and protein content in the production of UHT milk and

evaporated milk.

1.2 Options and variants

Compact and flexible Operating Unit

Hygienic process connection and easy cleaning

Water cooling and air flushing

The compact Operating Unit is extremely flexible and can be installed anywhere thanks to a serial interface - either in its own stainless steel housing or into a control cabinet on site. The measured values and status information can be read off this unit and output to the automation system. This unit is also used to input laboratory values for recalibration.

The Analyzer Unit is connected to the process without any contact via an optical window in the VARINLINE® measuring section.

The measuring section housing conforms to the FDA. In addition, cleaning is easy using the SIP/CIP method.

The use of water as a coolant is necessary at higher ambient temperatures and when measuring hot media. The OPTIQUAD Analyzer Unit can be optimally cooled that way.

Air can be flushed in to prevent condensation on the optical window.

OPTIQUAD-M 4050 W


Optimised sampling and easy recalibration

Less maintenance, more stability

Taking samples and analysing them in the laboratory is typically how the OPTIQUAD is verified.

Thanks to the integrated sampling valve with operating key, sampling campaigns are simple.

The reference values determined in the laboratory are then input into the Operating Unit and recalibration is performed at the touch of a button.

Compared to typical laboratory and bypass devices, no daily recalibrations are necessary when operating the OPTIQUAD. As there are no moving parts, high long-term stability and thus minimal maintenance is achieved. In addition, the optical window remains "automatically" free of any coatings thanks to the cleaning cycles performed by the dairy.

1.4 Measuring principle

The OPTIQUAD uses several light sources to measure the substances. Depending on the measuring task, up to 4 optical processes and 12 wavelengths are used. They are coupled into the medium via the optical window and measured with appropriate sensor elements, depending on the analytical process. The multitude of raw measured values is fed into a mathematical model which determines the protein and fat content.

Advantages of the measuring principle:• Unique combination of 4 optical measuring processes in one Analyzer Unit• Synchronous measurement of transmission, scattering, fluorescence and refraction• 12 different wavelengths of UV/VIS/NIR/IR, 200 to 4000 nm

OPTIQUAD-M 4050 W


3.1 Intended use

OPTIQUAD is a spectroscopic analysis system that uses up to 4 optical processes (transmission, scattering, fluorescence and refraction) and up to 12 wavelengths.

Measurement is done inline, is non-contact, continuous and precise, using no bypass, sampling or moving mechanical parts. The result is wear-free and extremely low-maintenance inline measurement. Recalibration is only necessary at very large time intervals, depending on the application.

The main area of application is in determining the protein, fat and lactose content in milk products.

It is primarily the optical data of the medium that is recorded and the temperature of the medium is measured. From these parameters, stored mathematical formulas and calibration data specific to the application are used to calculate the protein and fat values.

3.2 General installation conditions

The Operating Unit, an industrial PC with touch screen and built into a stainless steel housing, is installed at the customer's site following delivery or, if ordered as an option, the industrial PC with touch screen is integrated into an existing control cabinet on site and then electrically connected.

As a rule, the Analyzer Unit is completely preinstalled and delivered with the VARINLINE® measuring section that was ordered. This complete measuring system must then be installed in the pipeline at the customer's site. Depending on the conditions on site, the following installation positions are possible:

Horizontal pipelines• Standard: horizontal Analyzer Unit (at 90° to the pipeline)• Alternative: for technical reasons, the temperature sensor and the sampling valve with

operating key are installed on separate VARINLINE® measuring sections.

Vertical pipelines• Standard: Analyzer Unit at 90° angle to pipeline• Alternative: for technical reasons, the temperature sensor and the sampling valve with

operating key are installed on separate VARINLINE® measuring sections.• Flow direction from bottom to top

It is recommended to have an intervisibility between the Operating Unit and the Analyzer Unit. This makes sense predominantly in terms of recalibration and potential system checks.

The pressure-bearing parts have been designed and rated for stationary operation taking into account the maximum pressure and temperature.

3.3 Installation of the Analyzer Unit

3.3.1 Mechanical load relieving

Especially in the case of pipeline vibrations the Analyzer Unit should be relieved from mechanical loads.

If installed horizontally, the intended mounting ring may be used as needed to mechanically support the Analyzer Unit or to hang it on.

The Analyzer Unit should be installed where easily accessible.

3.3.4 Installation position and horizontal or vertical distances

When installing, choose a location in which the Analyzer Unit is easily accessible. The sampling valve and operating key in particular must be easily accessible.

Since the Analyzer Unit must swing down for the system check, there must be enough space below.

When installing the Analyzer Unit, there must be at least 725 mm / 2.4 ft space left underneath, measured from the middle of the Analyzer Unit.

3.3.5 Influence of built-in components

Pipe bends, valves, gate valves, pumps and other built-ins can have an influence on the product and thus on the measurement. For this reason, the results must be checked following any change in the production process and, if necessary, recalibrated.

In the event that the product has not been sufficiently homogeneously mixed, a stationary mixer 4 is recommended.

3.3.6 Water cooling and air flushing

Air can be flushed in to prevent condensation settling on the optical window.

The use of water as a coolant is recommended at high ambient temperatures and when measuring hot media. This allows water to completely flow through the outer jacket of the MFT and the Analyzer Unit to cool it.

Refer to "Technical data" for the exact requirements regarding purge air and cooling water.

Materials and tools required for installation are not included in the scope of delivery and must be provided by the customer.

3.4 Installation of Operating Unit

The Operating Unit is available in the following versions: Industrial PC with touch screen display, parameterization and calibration in a stainless steel housing or installation in a control cabinet on site.

It is recommended to have an intervisibility between the Operating Unit and the Analyzer Unit. This makes sense predominantly in terms of recalibration and potential system checks.

Figure 3-10: Wall mounting of Operating Unit in stainless steel housing

1 Horizontal distance between drill holes: 190 mm / 7.48"2 Vertical distance between drill holes: 210 mm / 8.27"3 Recommended distance to the wall: 5 mm / 0.20"; spacers to be provided by customer4 Assembly bracket (optional)5 When selecting the screws, bear in mind the weight of the Operating Unit!

To guarantee protection category IP65, the Operating Unit may not be installed directly on the wall. We recommend, therefore, the use of spacers 3. They guarantee that the drill holes on the rear wall of the Operating Unit are sealed.
