Energy-efficient and safe packaging thanks to centralized vacuum supply
A total of 200 tons of fresh meat products and 95 tons of meat and cold meat products are supplied daily by the production plants of Südbayerische Fleischwaren GmbH to EDEKA stores and other EDEKA Südbayern businesses.
(firmenpresse) - The vacuum required for packaging the goods in the production plants is generated by vacuum pumps from Busch Vacuum Solutions. As a result of the positive experiences at the production plant and the cutting plant of Bayernfleisch GmbH, a 50 percent subsidiary of S
S
The Obertraubling meat products plant mainly produces raw and cooked sausages in shift operation. Between 22 and 24 tons of raw and cooked sausage products leave the factory on a daily basis. Products are packaged on four packaging lines with thermoforming machines. Originally, a vacuum booster and a rotary vane vacuum pump were each installed in these machines to supply the packaging machines with vacuum for thermoforming the bottom film and for evacuating the vacuum chamber.
Due to the very good experience with central vacuum systems in the production plant in Traunstein, plant manager Walter Stemplinger also considered the option of centralization. The main thing that triggered this was the shutdown of a packaging line during the annual maintenance work on the vacuum pumps. He also wanted to eliminate the radiated heat from the vacuum pumps from the cooled packaging room and reduce noise emissions. He contacted the vacuum experts from Busch, who had already designed and built the systems for Bayernfleisch and the meat plant in Traunstein.
The space conditions in the production and packaging areas posed a challenge. To be able to satisfy the increasing demand, the meat plant in Obertraubling has undergone a series of expansions in recent years. Nevertheless, there was no room for the installation of a central vacuum system in the packaging area, which was last expanded in 2015. The vacuum experts from Busch then designed a vacuum system that fitted into a 20-foot container. Busch supplied this vacuum system, essentially consisting of four PANDA vacuum boosters, four R5 rotary vane vacuum pumps as backing pumps and a control cabinet completely mounted in the container. The buffer tanks were mounted on top of the container and all four packaging lines were connected to them.
The packaging chambers are evacuated in two steps with two vacuum supply lines. In the first line, there is a constant so-called rough vacuum of 30 millibars. This enables fast evacuation to the rough vacuum level. Once this has been achieved, the system switches to the second line with a vacuum level of 4 millibars. This two-stage pressure equalization method facilitates short cycle times. The buffer tanks on the container and the volume of the 18 to 25 meter long suction lines ensure that the necessary vacuum levels are permanently present in the lines. For the thermoforming of the bottom film, the rough vacuum level is completely sufficient, so that the forming tools are only exposed to this vacuum. The system is operated according to demand. Depending on the pressure, the individual vacuum pumps are switched on or off using pressure transmitters. This means that, in contrast to the previous decentralized vacuum supply, not all vacuum pumps are in operation at all times.
The vacuum supply is now fully redundant. This means that for the maintenance of individual vacuum pumps, these can simply be uncoupled via valves without this affecting active operations. The service technician no longer has to enter the hygienically sensitive packaging area. Thus, the annual service of the Busch vacuum supply is carried out during ongoing operation. After the plant was started up in 2018, the production plant manager in Obertraubling can today confirm: "If service work is being performed on the vacuum supply, nobody notices this at packaging lines."
It was possible to significantly reduce noise emissions by removing the individual vacuum pumps from the packaging room. The cooling of the packaging room could now also be reduced because the heat emitted by the vacuum pumps is no longer emitted into the ambient air. This and the demand-driven control of the vacuum supply contribute to a reduced energy consumption. Due to the energy savings and the easy service during operation, S can be sure that the vacuum supply is always fully functional.
