The challenge: Intelligent solutions for the

food & beverage industry.

To perform well, you have to be constantly improving. This is particularly true for com-panies in the food industry, and for their suppliers. This sector, more than virtually any other, requires ongoing change, sometimes with extremely short product life cycles. In the consumer market in Germany, for example, 600 new items and product variants are brought out every week, according to the GfK Group. For each product, strict hygiene regulations and legal requirements must be observed.

KROHNE meets these challenges, and provides its customers in this highly competi-tive market with well thought out, „state of the art“ solutions covering all areas of measuring technology.

This exceptionally wide range includes measuring devices for the fields of storage and intermediate storage, dosing and the mixing of conductive and non-conductive products, bottling and dosing, and products for the area of CIP cleaning.

Practical areas of application are found in all stages of food manufacturing, processing and refinement. These applications range from measuring the tank level of soft drinks using radar to batch filling PET bottles with fruit juice down to the precise dosing of liquid hops extract in a large brewery.

We even have the right technology for difficult applications such as processing honey and chocolate or measuring the flow of low-conductivity water in mixing stations for soft drinks. Wherever KROHNE measuring devices are used, they get the job done precisely, reliably and economically – you can count on it.

The König-Brewery, Duisburg and KROHNE:

Premium technology for a premium product.

The König-Brewery in Duisburg can look back on nearly 150 years of history. It was founded by Theodor König in 1858 in the small country town of Beeck near Duisburg. At a time when simple, top-fermented beers were the order of the day, König went against the general trend and decided to use the more elaborate Pilsener brewing process.

The strategy worked. By 1900 the brewery was supplying a whole range of locations around Beeck and Duisburg, with an output of almost 50.000 Hectoliters.

Today, their output is around 1.4 million hectolitres. Along-side the established brands König Pilsener and König Pilsener Alcohol-free, the beer-based mixed drink König Pilsener Lemon has been produced and bottled in Duisburg since March 2006.

340 highly qualified staff work day after day to ensure the success of the König Pilsener brand. König Pilsener.

The König-Brewery stores its hops and malt supplies in 23 square cement silos, each meas-uring 22 metres in height and with a capacity of 100 tonnes per silo. For years, the brewery has relied on KROHNE measuring devices based on guided microwaves to constantly monitor the silo levels. The advantages? The storage volume is used to optimal capacity, there are no more planning uncertainties or partial fillings and the company can order in advance, thus cutting costs.

The newly developed OPTIWAVE 6300 offers an even more advanced concept when it comes to measuring the level of solids in high tanks. The radar-based device features a drop antenna and was specifically designed to measure powders and solids in extremely dusty environments. The elliptical shape of the antenna prevents build-up and generates a small beam angle to accurately measure the silo contents. The high signal dynamic also ensures that measurement is precise, even with moving surfaces.

The task is challenging. You have to ensure that the ratio of malt and mashing water is correct. The OPTIFLUX 6300 must also carry out exact dosing of sparging water later in the brewing process, for optimum leaching of the residue in the lautering kettle.

The OPTIFLUX 6300 electromagnetic flowmeter performed well in both positions. On hand, the device features an outstanding new seal concept. The molded gasket has the largest sealing force at the front towards the process pipe. This reduces the danger of the seal being pushed out of place to an absolute minimum. As a result, when the seal expands during the cleaning process, it only extends backwards into the expansion chamber. This guarantees a hygienic seal and also increases its working life.

On the other hand, the device is already fitted with the innovative IFC 300 signal converter. This converter offers application and device diagnostics as standard, making installation and operation particularly simple and user-friendly. Even the high ambient temperatures in the brewing house are no problem for the IFC 300.

If you don‘t have the right temperature, you can‘t get anywhere with the mashing and boil-ing processes in the brewing house. That‘s why the TTP 200 temperature sensor from KROHNE measures and checks both processes in both the mashing kettle and the lautering kettle.

In the sensor casing of the TTP 200 there is a Class A PT 100 chip as standard (2, 3 or 4-wire), which complies with EN 60751. This guarantees very fast response times, even with very short installation lengths with reduced measuring tip. These compact thermometers are available with a broad range of standard signals, depend-ing on the head-mounted transmitter selected.

To achieve optimum conditions during the heating process in the brewing house, the exact quantity of heating steam must be measured. Important data about the consumption of heating steam can be gathered by taking the measurement.

The OPTISWIRL 4070 vortex flowmeter from KROHNE performs impressively. It can meas-ure steam usage to within 1% of the measured value. The high measuring dynamic of the OPTISWIRL 4070 measures the smallest flow quantities just as precisely as the larger ones.

On top of that, the OPTISWIRL is the firstvortex flowmeter with integrated pressure and temperature compensation. Additional sen-sors are no longer required. Not only does this reduce installation and wiring costs but it also results in maximum accuracy.

As the OPTISWIRL 4070 is not sensitive to ex-ternal vibrations, it can be easily mounted near a mash pump without disturbing or interrupting the measuring process.

Correctly and precisely dosing the hops is without a doubt one of the key steps for measuring systems when converting hops into a fin-ished beer. It is one of the most im-portant factors responsible for the taste and quality of the beer. The hops are put into the wort copper during the brewing process. The wort is heated as hops are added and the extract value is set according to the degree of steam-ing. Precisely dosing the hops optimises the cooking process and minimises the amount of hops ex-tract required. As the hop extract is not conductive and is very viscous, it is kept in a pourable state in a heating cabinet. This is a worth-while preparation because the OPTIMASS 7300 can then dose the flowing hops extract into the wort copper with a measuring accuracy of 0.1 %. This high measuring pre-cision is good for both the flavour and the brewery balance sheet.

The capabilities of the OPTIFLUX 6300 can also be used for measuring the flow of wort from the mashing kettle to the mash filter.

It is extremely important to meas-ure the wort quantity before it reaches the mash filter. After all, the operation of the mash filters is determined based on this value. This measurement also provides valuable information about how full the filters are and their remaining lifespan.

using the OPTIFLUX 6300.

The OPTIFLUX 6300 meets these challenges admirably. With an operating pressure of up to 6 bar and a measuring range of up to 2.820 hl/h, the electromagnetic flowmeter measures wort quanti-ties with great accuracy, regard-less of whether the compact or stand-alone version is used.

As the OPTIFLUX leaves the factory with a vacuum-proof liner, it can also be easily used in areas where high temperatures and vacuums are common.

To ensure fast and consistent brewing of the beer wort in the cylindrical-conical brewing tank, sterile air must be distrib-uted consistently into the wort using a system of nozzles. The quantity of sterile air depends on the flow volume to the brewing tank, and also on the number and state of the dosed yeast cells.

The H250 variable area flowmeter from KROHNE does a first class job. The only all-metal variable area flowmeter certified by the EHEDG continuously measures the air from the wort pipe to the brewing tank at an operating pressure of up to 6 bar. Adding yeast and air, the brewing phase can now begin in the cylindrical-conical tank. The extract in the wort is then converted into CO2 and alcohol. For bottom-fermented beers such as pils, this process takes around 5-8 days.

Fruit juice

18

Traditionally, Germany has the world‘s highest per capita con-sumption of fruit juice. The last 60 years have seen an increase from 1.9 to 41 litres. The fruit juice industry in Germany comprises some 450 fruit juice producers with approx. 7.500 employees, result-ing in a total turnover of 3.5 billion Euros. To produce 4.3 billion litres of fruit juice, fruit nectar and fruit juice drinks, more than 800.000 tonnes of fruit are processed.

Eckes-Granini and KROHNE: Superior measuring accuracy for

popular classic brands.

All over the world, leading fruit juice producers and plant engi-neers use state-of-the-art flow, level, temperature and pressure measuring equipment from KROHNE for a variety of processes. Famous examples include the KHS production plant and the fruit juice producer Eckes-Granini Deutsch-land GmbH. The latter started Germany‘s most modern PET juice bottling plant in 2006 and another was added in 2008.

When producing fruit juice, a large portion of the juice is made from concentrate. The concen-trate, which is delivered by vari-ous suppliers, is highly viscous at temperatures of around 4 °C. It is transferred from the concentrate containers such as tankers or vats into the concentrate storage tanks using Coriolis mass flow measure-ment.

The OPTIMASS 7300 is the first choice for measurements in the storage tanks and for mixing. This high-end device from the OPTIMASS mass flowmeter range features a revolutionary straight design with just one pipe, making it eminently suitable for measur-ing the highly viscous concentrate. The single pipe design also makes emptying and cleaning the device simple and straightforward.

Working at an operating pressure of up to 10 bar, the OPTIMASS does not just give reliable flow measure-ments. It also continuously calcu-lates the Brix value by measuring the density which directly corre-lates to the BRIX value of the fruit juice concentrate.

The correct ratio of concentrated fruit juice, water, sugar and additives largely determines the flavour, the look and the quality of a fruit juice.

This is not the only reason why it is very impor-tant to dose the correct quantity of water to the collection tank at the sugar dissolving station. The exact ratio of the water feed to the quan-tity of sugar also determines the subsequent BRIX value of the finished sugar syrup, which is required to produce fruit juice and soft drinks.

The OPTIFLUX 6300 electromagnetic flow-meter from KROHNE is ideal for this task. It does more than just reliably measure the flow of process water into the collection tank. The excellent measuring performance of the flow-meter guarantees exact dosing of the correct quantity of water.

But that is not all. Using its diagnostic func-tions, the unit controls the sensors and the electronics cyclically. The built-in application diagnostic also recognises situations such as partial filling, low conductivity or damage of the liner.

As already mentioned in the section on flow measurement and dosing of process water in the sugar dissolving station, the exact ratio of water feed to the quantity of sugar determines the later BRIX value of the finished sugar syrup.

For this reason it is vital to continuously meas-ure the density and BRIX value of the highly viscous sugar syrup in the sugar dissolving station, to avoid variation in quality. The OPTIMASS 7300 is ideally equipped for this task.

As well as directly measuring the density and mass, the device can also measure the volume and temperature of the product.

To increase the shelf-life of the fruit juice, it is heated briefly to temperatures from 70 to 85 °C. The exact temperature depends on the type of fruit juice. It must be kept at the temperature for about 15 to 30 seconds to ensure safe pas-teurisation and to make the juice last.

Monitoring the flow volume in the flash pasteuriser is ex-tremely important as the flow speed determines how long the juice spends in the pasteurisation unit, which in turn determines whether the pasteurisation is effective.

The OPTIFLUX 6300 flowmeter easily accomplishes this task. The device‘s high measuring accuracy makes it possible to keep the flow speed of the juice in the pasteurisation unit constant.

The shape of the PFA liner is maintained by a stainless steel mesh behind it, ensuring precise and reproducible results even at high operating temperatures.

To optimise the production phases in fruit juice manufacturing while minimising waste, it is vital to continuously measure the flow of juice in the pipes to the storage tanks.

This is a typical task for the hygienic magnetic flowmeter from KROHNE. Excellent measuring performance is not the only outstanding feature of the compact OPTIFLUX 6300 electromagnetic flowmeter. It also offers the user a broad meas-uring range of up to 300 m3/h. The hygienic adaptation is guaranteed by a variety of hygienic process connections.

specifically developed for the pre-cise filling and dosing of drinks of any kind. Thanks to its high meas-uring accuracy and repro ducibility, the BATCHFLUX has already proven its effectiveness in many rotary fillers for filling thin-walled PET bottles of various sizes.

The extremely high reproducibility is largely thanks to the ceramic lining, which retains its shape and is vacuum-proof at temperatures of over 130 °C despite frequent internal cleaning.

The new generation BATCHFLUX 5500 also handles difficult applications, including those with fibre content or hot filling, precisely and with good reproducibility.

When cold filling following pasteurisation with KHS-ACF-(Aseptic-Cold-Filling) technology, KHS uses electromagnetic flow-meters by KROHNE.

ACF filling combines several bene-fits in a single process: Firstly, it is a filling method that is particularly gentle on the product, which is in turn reflected in the flavour of the juice. In addition, unlike with hot filling, the use of preservatives can be avoided. Cold-filling also has particularly high hygiene standards for the devices used in the filling system.

After the milk has passed through the air separator, it is cooled to around 3 °C and then pumped into the milk storage tanks.

The level is normally measured by hydrostatic pressure transmitters, which are mounted in the base of the tank using hygienic process con-nectors.

Because of the condensation that accumulates on the outside of the tank and runs down the walls, the pressure sensor must be well pro-tected to prevent moisture from entering.

When determining the fat content of drinking milk as required by law, a separator is used to divide the pre-warmed raw milk into cream and skim milk. The milk is heated up to about 55 °C to reach a better degree of separation.

The skim milk leaves the separa-tor with a constant fat content of about 0.05 percent. The cream, which has a fat content of between 30 and 35 percent, is then partially pasteurised.

To smoothly separate the skim milk from the cream, the separat-ing processes in the inflow of the separator must be kept constant. Otherwise, new stationary con-ditions would constantly appear in the barrel. In this case, the OPTIFLUX 6300 provides accurate measuring results.

In order to eventually produce standardised milk with a specific minimum fat content (1.0, 1.5 or 3.5 percent), in addition to deter-mining the volume flow of the skim milk, the fat content of the cream must also be accurately measured.

At the core of this is an OPTIMASS 7300 Coriolis mass flowmeter. Thanks to its extremely good density measurement, it is possible to accurately determine the fat content of the creamThe device continually detects changes in the fat content, mean-ing that interventions can be made to correct any fluctuations.

The OPTIMASS 7300 boasts a spe-cial design with a single straight measuring tube. The sensor is ideal for shear sensitive products as there is no flow splitter or reduction in the diameter, thus keeping the flow velocity constant.

In addition, the sensor causes al-most no pressure loss in the device and is self draining. This is particu-larly advantageous when dealing with extremely sensitive products such as cream or butter.

The OPTIMASS 7300 is more and more becom-ing the standard flowmeter used in the produc-tion of cream cheese. One well-known producer of cream cheese and spreads from the Allgäu region in Germany uses it for virtually all flow measurements and dosing.

With spreads, one of the keys is to maintain the right ratio of base product and vegetable mix. After all, the end product should maintain constant for the consumer and taste the same from year to year. Due to the high viscosity, low conductivity and high fat content of the prod-uct, this is no easy task and one at which other measuring instruments fail. But not the OPTIMASS 7300. It provides the exact desired results with its outstanding reproducibility.

„The right ice cream, whatever your taste“ has been the motto of Nestlé Schöller since 1937. Employees produce several hun-dred different ice cream products, including milk-based ice cream in family packs and ice cream cones as well as 360 popsicles a minute. The company thus enjoys an outstanding position in the highly competitive ice cream market.

Using KROHNE measuring devices is one way for Nestlé Schöller to ensure its competitive edge. In the interests of cost efficiency, it is increasingly important to measure the throughput of individual filling and packaging machines. Take freezers for example. They cool the ice cream mix after pasteurisation

Here, Nestlé Schöller relies on the OPTIMASS 7300. The high-end device from the Coriolis mass flowmeter OPTIMASS family pre-cisely measures the dosing of the liquid mix before it goes into each single freezer. Thanks to its revolu-tionary single tube design, not only does it ensure excellent measur-ing performance, not disturbed by inhomogeneous mixtures or air pockets, but it also ensures meas-urements with minimal pressure loss. The device is also easy to empty and clean.

Hygiene is the highest priority in food production. CIP – Cleaning In Place – is an economical and time-saving process for cleaning proc-ess systems quickly and reliably. All parts of the system in contact with the product such as pipes, containers and heat exchangers are flushed with different clean-ing agents – usually water, acid and bases. To clean as effectively as possible, the concentration, temperature and flow speed of the cleaning agents are constantly monitored and maintained at a previously defined optimum value.

Complete separation of the water, the acid and the base is important for re-use of the cleaning agents in the CIP system. The faster the change between the different stor-age tanks is carried out, the more frequently the cleaning agents can be used.

38 KROHNE Communication

Industrial automation in the proc-ess industry has been undergoing rapid change for the past twenty years. This is also reflected in the processes of the food and bever-age industry. Where it was once centralized and largely self-con-tained structures that dominated, today the pace is set by intelligent, decentralized architectures.

Thus, system concepts in which the products of a variety of manu-facturers work harmoniously together are becoming a reality via open, standard interfaces such as HART, PROFIBUS and FOUNDA-TION FIELDBUS.

KROHNE has been actively follow-ing this development for years. Whether it is batch dosing and mixing, radar level measurement or CIP cleaning: KROHNE field de-vices are open for the future. They communicate reliably with control-lers, control systems and PCs and can also be used for a wide variety of control and regulating tasks.

PACTware and all KROHNE DTMs are available free of charge and fully functional without a license. They are included on a CD with each delivery of the device and are available in the KROHNE download centre.

Communication at KROHNE: Open for the future.

But KROHNE field devices can do much more. They meet all of the conditions for integration into plant asset management systems. And they make the use of innovative integration technologies such as FDT/DTM possible.

What‘s so special about FDT/DTM? For the first time, bus-independent integration of field technology into the plant asset management system is possible – this is without a doubt a milestone for industrial communication, something in which KROHNE, as a long-standing member of PACTware and the FDT group, has a considerable share.

Thus, since the beginning of 2003, we have been providing DTMs in the FDT 1.2 versions for a variety of field devices with HART and/or PROFIBUS interface.

Calibration at KROHNE: Safety you can count on.

39Calibration KROHNE

The true quality of a flowmeter only really shows through under adverse conditions: for example, when pressures and vacuums are fluctuating heavily or when measuring inhomogeneous products or media with high solid content.

That is why, starting with the calibration, we at KROHNE do everything to ensure that our flowmeters perform impressively, with maximum accu-racy, reliability and reproducibility, even under such conditions.

And that is why, for example, every KROHNE flowmeter is wet-calibrated in a direct comparison of volumes, which is the most accurate calibration method by far. Calibration takes place for both electromagnetic and ultra-sonic flowmeters using the world‘s largest calibration station at KROHNE Altometer in Dordrecht, in the Netherlands.

The accuracy of the KROHNE calibration stations is generally 5 times better than that of the flowmeters to be tested. For our customers, this not only means a maximum degree of certainty, but also guarantees the accuracy data of all flowmeters under reference conditions.

An added bonus for our customers: KROHNE supplies the largest NKO-certified flowmeters worldwide. This guarantees the highest degree of measuring accuracy – even under difficult operating conditions.
