The beer we drunk is clear, but before that, it is not. So it must be filtered after saccharifying and fermentation. The filter press is the necessary filtering equipment, especially gasketed filter press.
For the wort filtering, generally, it adopts the general filter press to remove the spent grains. But for the beer after fermentation, it contains the yeast and the germ etc, so it must be filtered by the fine filter press to ensure it has high best clearness and taste. Generally, it adopts diatomite filtering method and the paperboard filtering method.
