Atlas Copco central vacuum stations supply packaging strains at Tönnies BeefVacuum expertise helps beef keep recent for longer

The Tönnies Group has built its bovine animal competence middle in Badbergen, Lower Saxony. The cuts of beef are vacuum-packed in thermoforming and shrink-wrap machines, a course of that has become extra environment friendly than ever following renovations at the web site: Now, energy-saving Atlas Copco variable-speed vacuum pumps are used to create vacuum circumstances at two central stations.What was a blended slaughterhouse has turn into a “bovine animal competence center”: For many years, cattle and pigs have been slaughtered and butchered at the similar time in Badbergen on behalf of other corporations. In 2017, the Tönnies Group took over the positioning and decided to base its entire slaughtering operation in Badbergen – up until that point, this had taken place at the company’s main web site in Rheda-Wiedenbrück. In 2020, Tönnies Beef reopened the site after in depth conversion and renovation. The Group invested around eighty five million euro in the building and state-of-the-art expertise at this site in a small town in northern Lower Saxony, between Oldenburg and Osnabrück. The slaughtering, butchering and ending processes are based mostly on the newest cooling expertise, machine-based butchering and highly automated picking and shipping traces.
Several hundred tons of meat depart the site every day and 95% of the animal – practically everything – is utilized. This allows Tönnies to satisfy different consuming habits around the world: While German customers prefer lean beef, meat with a thick layer of fats is well-liked in Scandinavia and other European nations, based on the manufacturer’s web site.
Efficient screw vacuum pumps present forming, low and fantastic vacuums
“The cuts weigh between 1.5 and 9 kilograms after butchering,” explains Waldemar Metzger, Technical Manager of Tönnies Beef GmbH & Co. KG in Badbergen. The cuts are vacuum-packed for various main customers. For this function, Tönnies has put in a quantity of packaging strains within the halls: Seven thermoforming curler machines and two robot-operated shrink-wrap packaging machines. Efficient Atlas Copco vacuum pumps are used within the methods to hoover pack the tubular/shrink baggage and thermoformed plastic trays, and to maintain the meat actually contemporary. They work in two stations and provide forming, low and nice vacuums.
The thermoforming machines equipped by vacuum station 1. There are 4 Atlas Copco GHS 585 VSD+ variable-speed, oil-injected screw vacuum pumps that evacuate the air up to 40 mbar (absolute), as nicely as four small boosters that decrease the pressure even additional to three mbar. One of the screw pumps provides the forming vacuum for the thermoforming roller machines, which only require around a hundred to one hundred fifty mbar for the forming course of. The other vacuum pumps on this station are connected to the boosters. One of the pumps is redundant at any given time: This can additionally be the case within the second vacuum station, which includes 5 GHS 730 VSD+ pumps that take away the air from the shrink bags on the Cryovac strains. “The measurement of the cuts of meat is mechanically detected by our techniques,” explains Waldemar Metzger. “The packaging machines then automatically insert the cuts of meat into the tubular bags, which are cut to the right size underneath a vacuum bell.” Under the hood, all ambient air is then evacuated in two levels till the pressure is round three mbar (fine vacuum).
“With the forming vacuum – or thermoforming vacuum, as it’s also known as – the plastic tray is shaped by slicing the foil roll,” says the Technical Manager. After filling the shell with smaller items of meat, the shell is “wed” to the cover movie: The tool closes and seals the packaging hermetic at 3 to 5 mbar utilizing the nice vacuum. Sorting machines assign the individual trays and tubular luggage to bigger packing containers, which are then used to select customized boxes for buyer orders.
Efficient pace regulation reduces power necessities by a 3rd or more
Waldemar Metzger has been working in Badbergen for 20 years and has been part of the planning and execution levels of changing the combined slaughterhouse to a purely beef operation from the very beginning. This included the choice to purchase Atlas Copco variable-speed vacuum pumps. “As far as technology is concerned, with the ability to range the speed of the GHS vacuum pumps is crucial to us and saves energy,” stresses the Tönnies worker. “Compared to fixed-speed machines, you possibly can reliably reduce down vitality necessities by round a 3rd – even perhaps by half, depending on the range issue.”
The controls on the vacuum pumps have a user-friendly plain textual content display, which also indicates the working hours and maintenance intervals. Since Bonus could be connected on to an exhaust system, it was attainable to use air-cooled pumps. According to the manufacturer, this improves the local weather of the room; it is now not necessary to have the extra room cooling typically required when using central vacuum systems.
The challenge was carried out on website by and with Oliver Hornberg, Managing Director of Eugen Theis Vakuumtechnik in Werther. He delivered the pumps to Tönnies Beef, prepared to make use of – including a four hundred m pipeline within the converted slaughterhouse, measuring in locations to a diameter of DN 300. His firm, Eugen Theis GmbH, was founded in 1984 and focuses on vacuum technology. In 1999, Hornberg took over the enterprise from its founder, Eugen Theis, and 20 years later, in late 2021, bought it to Atlas Copco after he could not find a successor. “Our two kids are pursuing different career paths,” he says. Hornberg himself remains Managing Director even after the company was offered to Atlas Copco and is looking forward to important growth under the umbrella of one of many world’s largest suppliers of vacuum pumps. The firm already operates all through Germany: “From Flensburg in the north to Regensburg in the south and Halle (Saale) within the east,” he says, outlining the reach of his firm: This also includes Badbergen within the (north)west, as he generally stops by at Tönnies Beef to maintain the machines.
