Wort Separation

Mash Filters

Although lauter tuns are widely employed for wort separation, some large-volume brewers prefer mash filters. Mash filters are very much like plate and frame filters consisting of a series of grid-type plates alternating with hollow frame plates that are suspended on side rails. Each grid plate of the filter is covered on both sides with a monofilament polypropylene cloth. Accordingly, the grist serves no purpose as a filter medium and their particle sizes are of no consequence. Mash filters are more likely to be used in larger breweries where throughput and floor space are priorities.
