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

Top secret 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 process that has become extra 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 a blended slaughterhouse has become a “bovine animal competence center”: For many years, cattle and pigs have been slaughtered and butchered at the identical time in Badbergen on behalf of other firms. In 2017, 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 at the company’s main website in Rheda-Wiedenbrück. In 2020, Tönnies Beef reopened the positioning after extensive 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 finishing processes are primarily based on the latest cooling know-how, machine-based butchering and highly automated picking and shipping traces.
Several hundred tons of meat go away the positioning every single day and 95% of the animal – virtually every little thing – is utilized. This permits Tönnies to fulfill different eating habits around the world: While German consumers choose lean beef, meat with a thick layer of fats is in style in Scandinavia and other European nations, in accordance with the manufacturer’s web site.
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 numerous main prospects. For this purpose, Tönnies has installed a number of packaging lines 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 keep the meat actually fresh. 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 a lot as forty mbar (absolute), as well as four small boosters that decrease the stress even additional to 3 mbar. One of the screw pumps provides the forming vacuum for the thermoforming curler machines, which only require round one hundred to a hundred and fifty mbar for the forming process. The different vacuum pumps on this station are linked to the boosters. One of the pumps is redundant at any given time: This can be the case within the second vacuum station, which contains 5 GHS 730 VSD+ pumps that take away the air from the shrink baggage on the Cryovac traces. “The size of the cuts of meat is automatically detected by our methods,” explains Waldemar Metzger. “ Top secret packaging machines then routinely insert the cuts of meat into the tubular bags, which are cut to the right measurement beneath a vacuum bell.” Under the hood, all ambient air is then evacuated in two stages until the pressure is round 3 mbar (fine vacuum).
“With the forming vacuum – or thermoforming vacuum, as it’s also known as – the plastic tray is formed by chopping the foil roll,” says the Technical Manager. After filling the shell with smaller pieces of meat, the shell is “wed” to the quilt movie: The tool closes and seals the packaging airtight at three to 5 mbar using the fantastic vacuum. Sorting machines assign the individual trays and tubular luggage to bigger bins, that are then used to choose custom packing containers for customer orders.
Efficient pace regulation reduces energy requirements by a 3rd or extra
Waldemar Metzger has been working in Badbergen for 20 years and has been a part of the planning and execution stages of changing the mixed 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, having the flexibility to range the pace of the GHS vacuum pumps is important to us and saves power,” stresses the Tönnies employee. “Compared to fixed-speed machines, you probably can reliably cut down energy necessities by around a 3rd – even perhaps by half, relying on the variety 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 the Atlas Copco pumps could be linked directly to an exhaust system, it was attainable to use air-cooled pumps. According to the producer, this improves the climate of the room; it’s no longer essential to have the additional room cooling usually required when utilizing central vacuum methods.
The venture was applied on site 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 – together with a 400 m pipeline in the converted slaughterhouse, measuring in locations to a diameter of DN 300. His firm, Eugen Theis GmbH, was based in 1984 and specializes in vacuum expertise. In 1999, Hornberg took over the business from its founder, Eugen Theis, and 20 years later, in late 2021, bought it to Atlas Copco after he could not discover a successor. “Our two children are pursuing other career paths,” he says. Hornberg himself remains Managing Director even after the corporate was bought to Atlas Copco and is trying forward to vital progress under the umbrella of one of many world’s largest suppliers of vacuum pumps. The company already operates throughout Germany: “From Flensburg in the north to Regensburg within 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 typically stops by at Tönnies Beef to maintain up the machines.
