New Generation for Vacuum Packaging
With the development of the first ever rotary vane vacuum pump for the packaging of food, Busch has set the standards in the vacuum packaging industry. For decades, R 5 rotary vane vacuum pumps have been the leaders in providing vacuum for applications in food production, food process technology, food packaging as well as other vacuum packaging applications. Being optimized for operating around ultimate pressure and due to their high reliability and long service lifetime, they are regarded until today as the "packaging vacuum pumps par excellence". The R 5 RD is the new generation within the proven R 5 product family and the result of this continuous development.

Vacuum Packaging
Vacuum packaging helps to extend shelf life of fresh food considerably and has therefore become indispensable today. In particular, the extraction of oxygen plays a decisive role. This method prevents oxidation processes, preserving not only quality, texture and flavour of the packaged product but also its nutrients, vitamins and taste. Furthermore, aerobic bacteria multiply very slowly or not at all. Dry foods can be protected against moisture by means of vacuum packaging. MAP (modified atmosphere packaging) is mainly used for fresh meat, fish or convenience food. Atmosphere in the packaging is replaced by a gas mixture to maintain optical appearance, freshness and flavour.

Typical uses of R 5 vacuum pumps are in chamber machines, tray sealers and both the sealing and forming stations of thermoformers. They are used in countless food processes, such as meat and sausage production, cheese manufacturing, convenience food preparation and beverage bottling.

Central Vacuum Systems
R 5 rotary vane vacuum pumps are the perfect individual vacuum modules in a centralized vacuum supply for the packaging industry. Providing central vacuum systems is an area in which Busch has gained worldwide experience over many decades. Due to the accumulated know-how from thousands of installations, Busch can always provide the best vacuum solution meeting the specific requirements of each customer.

A centralization of the vacuum supply yields shorter evacuation times and still allows the packaging process to run with fewer vacuum pumps. The demand-driven control ensures that only as many vacuum pumps are in operation as are needed at any specific point in time. Considerable energy savings can be realized in comparison to a decentralized vacuum supply. Moreover, being installed outside of the packaging room, a central vacuum system helps to keep the production free from heat emissions, and maintenance can easily be carried out during operation.
