The method for filtering beer, comprises subjecting the beer to be produced to a shaking process in a container by producing mechanical waves through three or four vibration elements, and then guiding into a filter as unfiltrate. The vibration frequency of the vibration element is modulated in sinus form into frequency range between lower frequency of 90 Hz and upper frequency of 120 Hz or modulated with a phase duration of 3 minutes. The frequency range lies within a total frequency range of 30 to 220 Hz. The difference between the upper and lower frequency is 10-50 Hz.

The vibration frequency of the vibration element is modulated in sinus form into frequency range between lower frequency of 90 Hz and upper frequency of 120 Hz or modulated with a phase duration of 3 minutes. The frequency range lies within a total frequency range of 30 to 220 Hz. The difference between the upper and lower frequency is 10-50 Hz. The unfiltrate is filtered by a candle filter (1) or a membrane filter. The beer as unfiltrate is filtered after the fermentation process for beer clarification. The unfiltered beer is exposed to shaking process during the brewery process, before the fermentation process or after the brewery process. |
