Efficient and Flexible Drive Technology for the Doemens Academy

18 Aug 2022  |

For more than 100 years, the renowned Doemens Academy has been training the next generation in the brewing, beverage and food industries. Much has happened since the early days of the Brewery Academy. The state of the art is demonstrated by the pilot plant, which opened in 2021. In this new training and test brewery, 30 frequency converters and gearmotors from Danfoss each ensure efficient, precise, and safe processes. They are not only used for applications in the actual brewing process. Efficient and flexible drive technology also plays a central role in conveyor technology in the bottle cellar.

This is how things work at the Doemens training and pilot brewery

From the malt house via the brewhouse to the fermentation and storage cellar and then on to the bottle cellar with, among other things, filler, labeler, and packaging via the corresponding conveyor technology: The new technical center of the Doemens Academy reproduces the complete brewing process – driven by numerous geared motors and frequency converters from Danfoss. Where efficient and flexible drive technology is used in the brewery and what role it plays for more energy and cost efficiency is explained by Dr. Gerrit Blümelhuber from the Doemens Academy in the video tour of the new training and pilot brewery (see below).

Keeping things running smoothly: A flexible drive concept for the Doemens bottle cellar

Cans, bottles, kegs, crates: In the bottle cellar of breweries, heavy containers are moved on conveyor belts. At the same time, the containers – especially glass bottles – are particularly sensitive goods to transport. They must be transported efficiently, jerk-free and safely. The particularly high requirements for maximum hygiene standards in the beverage and food industry must also be considered and implemented in the transport technology. In addition, of course, it is always a question of transporting containers in and between the individual units in an energy- and thus cost-efficient manner.

New perspective: the journey through the box washer

How well do you know your bottle cellar? For example, have you ever driven through a box washer? No? Neither do we, but we dared to take the trip through the crate washer at the Doemens Academy’s Teaching and Experimental Brewery with the camera. Now we invite you to see the bottle cellar with different eyes. The ride of empty beer crates is a bit like a roller coaster ride – including acceleration, quick stops and cornering. All under controlled conditions, of course. This is made possible by the Danfoss drive technology used, which flexibly implements the requirements of the Doemens Academy.

In the bottle cellar of the Doemens Technikum, highly efficient frequency converters combined with extremely reliable permanent magnet motors of the ultra-premium IE5 efficiency class ensure efficient and smooth processes. They are part of Danfoss VLT® FlexConcept®, which offers numerous advantages. In this way, the beer crates are conveyed efficiently, precisely and safely through the crate washer. And as the name suggests, this drive concept, which was specially developed for conveyor systems in the food and beverage industry, is characterized by maximum flexibility: Depending on the system design, you can mount the Danfoss VLT® frequency inverters centrally in the control room or decentrally in the system close to the motor. In the new pilot plant of the Doemens Academy, a combination of 30 VLT® OneGearDrive® permanent magnet synchronous motors, 26 decentralized VLT® Decentral Drive FCD 302 frequency inverters, and 4 VLT® AutomationDrive FC 302 centrally installed in control cabinets ensures efficient conveying of the beverage crates through the crate washer and the bottle cellar. Christian Prakesch from Danfoss Drives and Dr. Gerrit Blümelhuber from the Doemens Academy talk about the demands that the transport technology in the new bottle cellar of the Doemens Academy places on the drive technology and how condition-based monitoring keeps an eye on the system:

In the end, it’s the end result that counts: Freshly washed and spruced up, the crates are ready to receive the precious commodity “beer bottle” and set off on their journey to the consumer. More about this case and others: Efficient and flexible drive technology | Danfoss Discover Drives
