Atlas Copco central vacuum stations supply packaging strains at Tönnies BeefVacuum expertise helps beef stay fresh 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 turn out to be more environment friendly than ever following renovations at the website: Now, energy-saving Atlas Copco variable-speed vacuum pumps are used to create vacuum situations at two central stations.What was once a combined slaughterhouse has turn into a “bovine animal competence center”: For many years, cattle and pigs were slaughtered and butchered at the similar time in Badbergen on behalf of different firms. In 2017, the Tönnies Group took over the site and determined to base its entire slaughtering operation in Badbergen – up till that point, this had taken place at the company’s main site in Rheda-Wiedenbrück. In 2020, Tönnies Beef reopened the positioning after intensive conversion and renovation. The Group invested round 85 million euro in the constructing 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 ending processes are based mostly on the most recent cooling expertise, machine-based butchering and extremely automated choosing and shipping lines.
Several hundred tons of meat leave the site daily and 95% of the animal – virtually everything – is utilized. This allows Tönnies to fulfill different consuming habits around the globe: While German customers choose lean beef, meat with a thick layer of fats is popular in Scandinavia and different European nations, based on the manufacturer’s website.
Efficient screw vacuum pumps provide forming, low and nice vacuums
“The cuts weigh between 1.5 and 9 kilograms after butchering,” explains Waldemar Metzger, Technical Manager of Tönnies Beef GmbH & Co. KG in xp2i . The cuts are vacuum-packed for numerous main customers. For this function, Tönnies has installed 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 in the systems to vacuum pack the tubular/shrink luggage and thermoformed plastic trays, and to maintain the meat actually recent. They work in two stations and provide forming, low and fine vacuums.
The thermoforming machines provided by vacuum station 1. There are four Atlas Copco GHS 585 VSD+ variable-speed, oil-injected screw vacuum pumps that evacuate the air as much as 40 mbar (absolute), in addition to four small boosters that lower the strain even additional to 3 mbar. One of the screw pumps supplies the forming vacuum for the thermoforming curler machines, which only require around one hundred to a hundred and fifty mbar for the forming process. The different vacuum pumps in this station are linked to the boosters. One of the pumps is redundant at any given time: This is also the case within the second vacuum station, which comprises five GHS 730 VSD+ pumps that take away the air from the shrink baggage on the Cryovac strains. “The measurement of the cuts of meat is automatically detected by our methods,” explains Waldemar Metzger. “The packaging machines then mechanically insert the cuts of meat into the tubular baggage, that are minimize to the proper dimension underneath a vacuum bell.” Under the hood, all ambient air is then evacuated in two levels until the strain is around 3 mbar (fine vacuum).
“With the forming vacuum – or thermoforming vacuum, as it’s additionally known as – the plastic tray is formed by cutting 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 device closes and seals the packaging hermetic at three to five mbar using the fine vacuum. Sorting machines assign the person trays and tubular bags to bigger packing containers, that are then used to choose customized boxes for customer orders.
Efficient velocity regulation reduces energy requirements by a third or more
Waldemar Metzger has been working in Badbergen for 20 years and has been part of the planning and execution levels of converting the combined slaughterhouse to a purely beef operation from the very starting. This included the decision to purchase Atlas Copco variable-speed vacuum pumps. “As far as expertise is worried, having the flexibility to range the velocity of the GHS vacuum pumps is essential to us and saves energy,” stresses the Tönnies worker. “Compared to fixed-speed machines, you can reliably cut down energy necessities by around a third – even perhaps by half, depending on the variety factor.”
The controls on the vacuum pumps have a user-friendly plain textual content display, which also indicates the working hours and upkeep intervals. Since the Atlas Copco pumps can be related on to an exhaust system, it was possible to make use of air-cooled pumps. According to the manufacturer, this improves the climate of the room; it’s now not necessary to have the additional room cooling usually required when using central vacuum methods.
The challenge was applied on website by and with Oliver Hornberg, Managing Director of Eugen Theis Vakuumtechnik in Werther. He delivered the pumps to Tönnies Beef, ready to make use of – including a four hundred m pipeline within the converted slaughterhouse, measuring in places to a diameter of DN 300. His firm, Eugen Theis GmbH, was based in 1984 and specializes in vacuum technology. In 1999, Hornberg took over the business from its founder, Eugen Theis, and 20 years later, in late 2021, sold it to Atlas Copco after he could not discover a successor. “Our two children are pursuing different career paths,” he says. Hornberg himself stays Managing Director even after the company was offered to Atlas Copco and is wanting ahead to vital growth beneath the umbrella of one of many world’s largest suppliers of vacuum pumps. The firm already operates all through Germany: “From Flensburg within the north to Regensburg within the south and Halle (Saale) within the east,” he says, outlining the reach of his firm: This also consists of Badbergen in the (north)west, as he generally stops by at Tönnies Beef to take care of the machines.
