Vibration during mashing improves brewing process

Shaken, not stirred: in order to achieve better extract yields in conjunction with shorter mashing times, Krones has adopted an entirely fresh approach for its Shakesbeer mashing system. Shakesbeer has proven its worth during numerous applications. A mashing time of less than two hours, uniformly heated mash and considerably reduced energy consumption are the most important features.
Vibration units integrated in the mash tun are a further improvement with a positive effect on the brewing process. The vibration units are installed in the mash tun, and function as a kind of agitator bottle. They are driven by an electric unbalance motor, surrounded by a metal cylinder. The motor is linked up with a programmable logic control system and is automatically switched on and off in the respective phases of the mashing process. Different frequencies can be generated as well.
Following more than a year of field experience with the vibration units, the following results have been verified:

• Increased yield 
• Improved lauterability of the wort 
• Improved filtering characteristics of the beers 
• Reduced oxygen loading in the mash

The vibration units can be fitted to every tun after appropriate technical clarification.
