Building a new brewery
Though the old brewery in Tromsö grew over the decades, space gradually became too limited, and the logistics increasingly expensive. Which meant that a few years ago Mack was confronting a key question: cease operations or build a complete new facility? The decision was swiftly taken: to invest in the brewery and upsize its capacities. So in 2012 Mack relocated its main production operations to an entirely new brewery in Nordkjosbotn, about 70 kilometres to the south of Tromsö.
Mack re-used some of the equipment from the old brewery, such as the fermentation and storage tanks, and parts of the filling kit. But the family firm also wanted to install new kit, such as the entire brewhouse. They opted for a CombiCube B rated at 100 hectolitres per brew, “the biggest CombiCube that Krones offers,” as Brewmaster Rune Lennart Andreassen proudly explains. In three-shift operation, ten brews a day can now be produced there from Monday to Friday.
We have to be able to rely on our partners.
The brewhouse also incorporates a Variomill wet mill, linked to a Botec F1 process control system. “Although the quality of the raw materials is subject to natural fluctuations, this means we can achieve very good stability within a recipe,” is Rune Lennart Andreassen’s verdict. “The CombiCube could be installed for a modest outlay, is easy to operate, and has proved its worth in actual operation. The 24-hour remote service by telephone, moreover, provides excellent assistance at need.” Harald Bredrup adds: “The CombiCube can be used flexibly for both small and large brews, and we can nevertheless brew continuously. Another plus is that the system works energy-efficiently at comparatively favourable capital investment costs.” Krones also installed the system for yeast propagation and recovery, and further additions are already being planned: “The next project with Krones will be a new CIP system,” says a forward-looking Rune Lennart Andreassen.
