After 40 years and 25 million hectoliters of beer, European brewer Forst decided that it was time to modernise its energy usage and meet its carbon emission responsibilities.
By designing a new brewery from scratch, the company not only achieved these aims but also managed to cut costs in the process.
Forst enlisted the services of NORD Drivesystems to power the new brewery. The aim was to reduce energy consumption by 30 per cent.
In just 16 months, five large vats, a newly designed water supply, and a malting plant with twelve silos (and three separate storage vats) had to be built at the 154-year-old Italian brewery.
NORD assembled the geared motors for all the vessels according to the specific requirements of the various applications.
The grinding mill gently grinds the malt at the start of the brewing process, while the screw conveyor removes the spent grain.
Then the liquid is pumped into the lauter tun. Here the liquid and solid parts are separated in a process that is fully automated.
Pressure sensors at the bottom of the vessel are used to detect the consistency of the spent grain which settles on the floor of the vat. Then the drive adjusts the machine’s speed accordingly. It can deliver flow rates of between nine and fourteen litres / minute.
There is also a custom-tailored NORD drive unit, a combination of a motor, industrial gear unit, and a helical bevel gear unit, with a maximum torque of 96,000 Nm. Its function is to make sure that the system runs smoothly. It continuously monitors speeds, current consumption, and motor temperature
Later stages are handled by various NORD drive motors and drives.
