Atlas Copco central vacuum stations provide packaging lines at Tönnies BeefVacuum know-how helps beef keep fresh for longer

The Tönnies Group has built its bovine animal competence center 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 on the web site: Now, energy-saving Atlas Copco variable-speed vacuum pumps are used to create vacuum situations at two central stations.What was once a blended slaughterhouse has turn out to be a “bovine animal competence center”: For many years, cattle and pigs had been slaughtered and butchered at the identical time in Badbergen on behalf of other corporations. In เกจวัดแรงดันอากาศ , the Tönnies Group took over the positioning and determined to base its complete slaughtering operation in Badbergen – up till that time, this had taken place on the company’s main website in Rheda-Wiedenbrück. In 2020, Tönnies Beef reopened the positioning after intensive conversion and renovation. The Group invested around eighty five million euro within the building and state-of-the-art expertise at this web site in a small city in northern Lower Saxony, between Oldenburg and Osnabrück. The slaughtering, butchering and finishing processes are based mostly on the latest cooling know-how, machine-based butchering and extremely automated choosing and delivery traces.
Several hundred tons of meat depart the location every day and 95% of the animal – virtually everything – is utilized. This permits Tönnies to satisfy completely different consuming habits around the globe: While German consumers prefer lean beef, meat with a thick layer of fat is well-liked in Scandinavia and different European international locations, based on the manufacturer’s website.
Efficient screw vacuum pumps provide forming, low and fine 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 varied main customers. For this objective, Tönnies has installed several packaging traces in 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 vacuum pack the tubular/shrink baggage and thermoformed plastic trays, and to maintain the meat actually recent. They work in two stations and supply forming, low and nice vacuums.
The thermoforming machines supplied by vacuum station 1. There are four Atlas Copco GHS 585 VSD+ variable-speed, oil-injected screw vacuum pumps that evacuate the air as a lot as 40 mbar (absolute), in addition to 4 small boosters that lower the strain even additional to three mbar. One of the screw pumps provides the forming vacuum for the thermoforming curler machines, which solely require round a hundred to one hundred fifty mbar for the forming course of. The different vacuum pumps on this station are connected to the boosters. One of the pumps is redundant at any given time: This is also 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 lines. “The measurement of the cuts of meat is automatically detected by our systems,” explains Waldemar Metzger. “The packaging machines then automatically insert the cuts of meat into the tubular baggage, which are reduce to the correct measurement under a vacuum bell.” Under the hood, all ambient air is then evacuated in two stages until the stress is around 3 mbar (fine vacuum).
“With the forming vacuum – or thermoforming vacuum, as it’s additionally referred to as – the plastic tray is fashioned 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 fantastic vacuum. Sorting machines assign the individual trays and tubular luggage to larger boxes, that are then used to select custom packing containers for customer orders.
Efficient velocity regulation reduces power requirements by a third or more
Waldemar Metzger has been working in Badbergen for 20 years and has been a part of the planning and execution phases of converting the blended slaughterhouse to a purely beef operation from the very starting. This included the choice to purchase Atlas Copco variable-speed vacuum pumps. “As far as know-how is worried, being in a position to vary the velocity of the GHS vacuum pumps is essential to us and saves vitality,” stresses the Tönnies employee. “Compared to fixed-speed machines, you possibly can reliably reduce down energy requirements by round a third – maybe even by half, depending on the variety factor.”
The controls on the vacuum pumps have a user-friendly plain text show, which also signifies the working hours and upkeep intervals. Since the Atlas Copco pumps may be related directly to an exhaust system, it was potential to use air-cooled pumps. According to the producer, this improves the climate of the room; it’s now not essential to have the extra room cooling usually required when utilizing central vacuum systems.
The venture was implemented on website by and with Oliver Hornberg, Managing Director of Eugen Theis Vakuumtechnik in Werther. He delivered the pumps to Tönnies Beef, ready to use – including a four hundred m pipeline in the transformed slaughterhouse, measuring in locations to a diameter of DN 300. His company, Eugen Theis GmbH, was based in 1984 and specializes in vacuum expertise. 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 couldn’t find a successor. “Our two youngsters 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 vital development underneath 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) in the east,” he says, outlining the attain of his company: This additionally contains Badbergen in the (north)west, as he generally stops by at Tönnies Beef to take care of the machines.
