(businesspress24) - Block House Fleischerei GmbH has made increasing energy efficiency and reducing greenhouse gas emissions its declared objective. The producer of portioned fresh meat products and burgers has achieved considerable energy savings and reduced CO2 emissions by 36.1 tonnes per year by reorganizing the vacuum supply for five vacuum lines. The core component of the new vacuum supply is a centralized vacuum system from the company Dr.-Ing. K. Busch GmbH. Thanks to its design and intelligent control system, it consumes significantly less energy than the vacuum pumps previously installed directly in the packaging machines.

Block House Fleischerei GmbH is a Block Foods AG company. At the modern meat processing plant in Hamburg, Germany, steaks are sliced into portions, cattle is dissected, and burgers and carpaccio are produced. Nearly 100 employees work in the one-shift operation, although burger production is done in two shifts. Some of the products go to the companyllion guests are served in these restaurants each year. The majority of the products are delivered to wholesalers, retailers or the gastronomy industry. Customers are mainly in Germany and neighbouring countries.

In 1973, the Block House butchery was founded by Eugen Block and the quality standards Block set back then still apply today; the IFS certification confirms the high quality of the fresh meat and burger products. The prime beef quality seal additionally guarantees that the meat used only comes from cows that were raised in a way that is appropriate to the species. The meat for the steaks mainly comes from Angus and Hereford cattle.
The Block House butchery feels the same responsibility for the environment and sustainability as it does for maintaining strict quality standards. The energy management system is certified according to ISO 50001 and is part of the

As early as 2013, the vacuum supply of the packaging machines was analyzed with regard to energy and it was determined that there should be savings potential here. At that time five packaging lines, each with one thermoforming machine, were each equipped with a rotary vane vacuum pump as a backing pump and an additional vacuum booster. These vacuum pumps were installed close to the packaging machines and thus in close proximity to the workplaces. The result was that the vacuum pumps emitted their waste heat directly into the production areas. It was only possible to maintain the low room temperature required for hygienic reasons by increasing the output of the air conditioning system. The noise pollution in the workplace was a further disadvantage.

In addition to saving energy and reducing CO2 emissions, the Block House butchery had an additional goal for the replacement of the vacuum supply: they also wanted to guarantee high availability of the vacuum supply and remove the vacuum pumps from the production areas to avoid waste heat and noise pollution in the workplace. Furthermore, maintenance personnel should not enter these areas if possible.

Together with the vacuum specialists from Busch, a concept was developed to find an energy-efficient solution that would also ideally eliminate all the other previous disadvantages. The team quickly agreed that central vacuum supply of the packaging machines would be the ideal solution. The basis for designing the centralized vacuum system was the five existing thermoforming packaging machines, which only require vacuum for the actual packaging process because the base foils are not sucked into the forms with a vacuum, but are rather blown into the forms with compressed air.

The new centralized vacuum system has been in operation since September 2015. Its main components are four R 5 rotary vane vacuum pumps with four Panda vacuum boosters.
One vacuum module consisting of one rotary vane vacuum pump and one vacuum booster has a purely stand-by function and is only used if maintenance must be performed during operation. The centralized vacuum system is one floor down, located underneath the production areas in a separate room and is thus completely separated from production.

The packaging chamber is evacuated in two steps with two vacuum supply lines. There is a constant so-called rough vacuum of 30 millibars in the one line. This enables fast evacuation to this that the required vacuum level is constantly available in the lines.
The system is operated according to demand. The individual vacuum modules are switched on or off depending on the pressure using pressure transmitters. Thanks to this control and 9.9 kilowatts less energy consumption than the previous decentralized supply, the Block House butchery has 4,356 euros in energy cost savings each year. The energy saved is equivalent to 22.8 tonnes of CO2 emissions.

Frank Damast, technical director at Block House butchery, is convinced that he installed the most advanced vacuum technology with the new centralized vacuum system from Busch and that this is also far superior to the previous vacuum supply when it comes to the level of maintenance and susceptibility to failures. The modular design makes it virtually impossible for the vacuum supply to fail. The stand-by vacuum module also offers an additional element of security.

The installation of the vacuum system in a separate room on a lower level enables savings of 23.1 kilowatts of cooling output for the cooling unit in the production areas. This corresponds to annual cost savings of 2,541 euros or reduces the CO2 emissions by 13.3 tonnes. If the energy cost savings of the centralized vacuum supply and the cooling output are added together, it comes to annual total savings of 6,897 euros. The total reduction of CO2 emissions comes to 36.1 tonnes. The centralized vacuum system currently supplies five packaging machines but is designed in such a way that two further packaging machines can be connected. In addition, this has enabled shorter cycle times.

The use of an innovative and energy-efficient vacuum supply was subsidized by the city of Hamburg through the

Maintenance of the centralized vacuum system is performed once a year by a Busch service technician who coordinates his visit beforehand with production engineering. By linking the centralized vacuum system to the operational process control system, it can be constantly monitored and possible irregularities can be immediately recognized. The power consumption is also automatically displayed and documented as a result.

Company information / Profile:

Busch Vacuum Pumps and Systems is one of the world’s largest producers of vacuum pumps, vacuum systems, blowers and compressors.
Its extensive product portfolio comprises solutions for vacuum and overpressure applications in all industries, including the chemical, semiconductor, medical technology, plastics, and food sectors. It also covers the design and construction of customized vacuum systems, as well as a global service network.
The Busch group is a family-owned company and is still managed by the Busch family. Busch Vacuum Pumps and Systems has 3,000 employees in more than 60 companies in over 40 countries worldwide. Busch is headquartered in Maulburg, in southwest Germany. This is the location of Busch SE headquarters, as well as the German production facility and German sales company. In addition to Maulburg, Busch also has its own production plants in Switzerland, the UK, Czech Republic, Korea and the USA.

Busch Vacuum Pumps and Systems was founded by Dr.-Ing. Karl Busch and his wife Ayhan Busch in 1963. Dr.-Ing. Karl Busch developed the “Huckepack”, which was the first vacuum pump that could be used for vacuum packaging of foodstuffs. The follow-up product, the compact “R 5” rotary vane vacuum pump, revolutionized food packaging. A further milestone represented the development of the “COBRA” screw vacuum pump. In 1971 the international expansion of the Busch group started with the founding of a sales company in the UK. The first production plant outside Germany was established in the USA in 1979.
