International technology group Andritz is presenting its unrivalled range of separation and filtration technologies for the beer industry at BrauBeviale in Nuremberg, Germany, from November 12 to 14, 2019, hall 7, booth 7-421. Experts from Andritz will be on hand to provide specialist support for a wide range of brewing processes from mash filtration to yeast beer recovery and beer filtration.

The solutions cover a wide range of separation and filtration processes and equipment needed for beer production – from filter presses and dynamic crossflow filters to decanters and separators.

One special product designed exclusively for the brewing industry is the Art Brew beer clarifier, the latest version of which will be showcased at BrauBeviale. Combining efficiency and ease of maintenance, Art Brew is a high-quality and simple-to-operate beer clarification solution, which comes as a plug-and-play unit for the craft beer industry but also in large sizes for industrial beer production.It comprises a unique inert-gas sealing system known as KO2 (knock-out oxygen) that prevents unacceptable levels of oxygen pick-up between the clarifier inlet and outlet connections. Thanks to its small dimensions and custom configuration, the Art Brew is not only highly efficient, but also a very compact solution that is quick to install. The Art Brew range caters to brewers of any size, with a beer clarification capacity ranging from 50 to 700 hectoliters per hour. Visitors will be able to explore the Art Brew’s control options and see the process clearly from close quarters.

Another separation technology that has proven its worth for producers of a wide range of beverages is the Andritz Dynamic Crossflow Filter (DCF). Its rotating membranes allow users to separate highly viscous sludges like surplus yeast up to yeast concentrations containing more than 25% by weight, thereby ensuring optimum yeast beer recovery with the highest filtration quality. Because breweries no longer have to dilute the yeast with water in order to process it, the filtered beer can be blended with the main stream without any impact on the quality or alcohol content. As a result, this method becomes an interesting alternative to traditional concentration technologies.

The membrane filter presses ensure that the effective filtration of mash is kept at a constant, high quality level. As filter press filtration is a sealed process, the risk of oxidation is kept to a minimum. Additional peace of mind comes from the fact that Andritz filter presses are not only easy to clean and come with the option of cleaning-in-place solutions, but the components also conform to FDA standards. In addition, brewery customers in particular benefit from the fact that Andritz filter presses can be adjusted to a variety of processes and recipes.

IIoT Technologies

With the development of Metris addIQ control systems, the company has taken the lead in IIoT (Industrial Internet of Things) solutions for solid/liquid separation processes and offers a wide range of innovative products and services under the Metris technology brand. These technologies allow the evolution of separation processes towards fully automatic operations. In addition to user-free operation, the biggest advantages lie in the fields of predictive maintenance and risk mitigation. The innovative automation solutions add a new dimension to the performance of production facilities by minimizing downtime and maximizing product yield, quality, and consistency – even for operations that are already up and running. Furthermore, they are completely scalable and backed by a specialist network of global automation experts.

One specific smart product that appeals to brewers is the intelligent filter press. Equipped with a Metris addIQ control system, the intelligent filter plate within the filter press is able to measure the residual moisture content in the spent grains while simultaneously monitoring this factor online. This means that the filtration process is always stopped at the ideal moment – gaining valuable filtration time and therefore a higher filtration capacity.

And the expertise doesn’t end with technology – whether customers need spare parts, rentals, local service, repairs, upgrades, or modernization of equipment, Andritz is a full-service provider. From initial consulting through to service agreements, process optimization, and training programs, Andritz specialists are always looking for ways to minimize downtime and increase predictability in operations while raising overall production efficiency. The network of 550 service specialists and global service centers ensures that the firm will always be there to support its customers for many lifecycles to come.

New high-performance vacuum pumps
Roots pumps series set new standards

Published

on

Pfeiffer Vacuum, provider of vacuum technology, is presenting the new and innovative Roots pumps of the Hi Lobe series which can be used for numerous industrial vacuum applications such as electron beam welding, vacuum furnaces or freeze drying. The pumps of the Hi Lobe series are of particular interest for fast evacuations (load-lock chambers or leak detection systems). Furthermore, they are suitable for use in coating applications.

Compact and powerful Roots pumps

The compact Roots pumps offer a wide nominal pumping speed range of 520 – 2.100 m³/h. This is made possible through the new drive concept in conjunction with frequency converters. Thanks to their individual speed control, the pumps can be precisely tailored to customer-specific requirements. Thanks to this powerful drive concept, the Hi Lobe achieves approximately 20 percent shorter pump-down times than conventional Roots pumps. Rapid evacuation reduces costs and increases the efficiency of the production system.

Process-reliable and cost-efficient vacuum

The maintenance and energy costs of the Hi Lobe are >50 percent lower compared to conventional Roots pumps. The reason for this is a drive with energy efficiency class IE4 and the special rotor geometries of the pumps. The sealing concept also contributes to this. The pumps are hermetically sealed to the atmosphere and have a maximum integral leakage rate of 1 · 10-6 Pa m³/s. Dynamic seals are eliminated and, as a result, maintenance is only required every four years. Due to the innovative sealing concept in the suction chamber, the use of sealing gas is superfluous in most applications, which also has a positive effect on the operating costs. Since the operation of the Hi Lobe Roots pumps is possible even at ambient temperatures of up to +40°C with flexible air cooling, cost-intensive water cooling is unnecessary.

Control and communication are the essential factors for increasing system availability. The intelligent interface technology of the Hi Lobe allows very good adaptation and monitoring of the processes. This facilitates anticipatory and efficient work. By integrating such condition monitoring, information about the condition of the vacuum system is always available. In addition, condition monitoring increases system availability allowing users to plan maintenance and repair measures in a useful and anticipatory way and prevent cost-intensive production downtimes. These advantages lead to a long service life and maximum operational safety. Depending on their suitability for the existing system, the Hi Lobe vacuum pumps can either be aligned vertically or horizontally. This allows maximum pumping speed and a more customized and efficient use of space at the customer’s production site.

Vacuum technology in research
Standstill for progress

Molecules are to be cooled down at the University of Stuttgart in order to exhibit their quantum properties. The researchers participating in the project hope that this will lead to insights for basic research. Pfeiffer Vacuum’s technology will be used to effectively isolate the extremely cold molecules from the much hotter environment. The company not only supports industry, but also customers from research and development with technology and advice.

Energy management, transportation, semiconductor electronics – many industries dream of superconductors at room temperature. Materials without electrical resistance have the potential to completely revolutionize numerous applications. However, superconductivity has so far only been seen at very low temperatures of around -180 degrees Celsius. In many cases, applications only become economically viable when this extreme cooling is no longer necessary.

As yet, however, it is as difficult to understand why some materials achieve superconductivity at comparably high temperatures as the question of whether this could even be possible at room temperature. What is certain is that there is a macroscopic quantum effect.

Ironically, researchers are seeking to understand these effects by using systems that generate even lower temperatures. At the University of Stuttgart, for example, experiments are being carried out to investigate the quantum effects of molecules that are cooled by special lasers to such an extent that their temperatures are only a few billionths of a degree above the absolute zero point of -273.15 degrees Celsius.

In contrast to previous experiments, molecules are to be cooled using lasers instead of atoms. The Stuttgart researchers are using an upstream helium cooling system due to the more complex molecular structure.

This is where Pfeiffer Vacuum’s technology comes in. “Alongside its excellent pre-vacuum compatibility, the Hipace 300 H is optimized for light gases such as hydrogen and helium,” explains Fabian Frey, Market Manager of Research and Development Customer Support. While his colleagues mostly deal with practical applications on a large industrial scale – semiconductor industry, coating, and automotive engineering – Fabian Frey finds the vacuum solutions for research institutions.

Frey is particularly enthusiastic about the pump’s handling of helium. “Along with hydrogen, this is one of the most demanding gases that can be pumped. The back diffusion in the pump system is particularly high and the efficiency correspondingly poorer. This is where the Hipace is the top performer in the market,” says Frey.

The experiments carried out by the Stuttgart researchers are mainly directed at developing new so-called quantum simulators. Quantum effects are sometimes so complex to calculate that they cannot be simulated even with the high computing power of contemporary supercomputers. Quantum simulators are used to investigate simplified models in experimental investigations. In the process, the cold molecules promise to provide exciting new insights. The findings could eventually lead to new technical applications such as quantum sensors or quantum computers, says Frey.

Significant advances could also be made in the understanding of quantum effects in superconductors and other materials. The system in which the molecules are observed is not large – it only occupies about three cubic meters. In order to reach and maintain the required low temperatures following precooling with helium, the molecules being investigated must be captured and cooled by lasers and magnetic fields in an ultra-high vacuum generated by the Pfeiffer Vacuum turbopump. This is because even the slightest contact with the outside world would immediately reheat the molecules. Due to the great challenges of the initiative, the current project has no specific duration; the research group will devote several years to basic research and during this time Fabian will support the customer with their vacuum needs. “This is an ongoing process, we go in and out of the customer’s facilities and usually visit them when vacuum technology advice is required,” he says. As a result, he is constantly up to date on the status of projects.

His company is well known in the research and development market, “because that is where our roots lie,” says Frey – after all, Pfeiffer Vacuum is the inventor of the turbomolecular pump. In addition to turbopumps, the broad product portfolio also includes backing pumps, measuring instruments, coating systems, leak detectors and mass spectrometers. The University of Stuttgart uses several Pfeiffer Vacuum products including vacuum pumps, mass spectrometers, pressure gauges, pumping stations and systems. Pfeiffer Vacuum’s technology is also used in the multinational ITER project, CERN and the Heidelberg Ion Beam Therapy Center.

Sectors such as the process industry, semiconductor production and analytics naturally contribute more to the mechanical engineering group’s sales than customers from research and development; however, R&D customers are working on future projects. “We’re proud to be part of it,” Frey says. He sees supporting the segment also as an investment in the future of his own company – after all, there are potential applications for other market segments. The process industry could one day also benefit from the fact that molecules in Stuttgart are brought very close to zero using Pfeiffer Vacuum technology.
