Title: REGENERATION PROCESSES FOR MEDIA USED IN THE TREATMENT OF FERMENTED LIQUIDS
Abstract:
This disclosure includes regenerated inorganic fermented beverage stabilization and/or clarification media and a process for such regeneration. Inorganic stabilization and clarification media (for processing beer or the like) may include expanded perlite or other expanded natural glasses, diatomaceous earth, silica gel or other precipitated silicas or compositions that incorporate these materials. Such media may be regenerated individually, together in a mixture or together as pan of a composite product. The regenerated media meet the requirements for physical and chemical properties for re-use and replacement of the majority of particulate inorganic filtration media and inorganic stabilization media consumed in stabilization and clarification processes, and the related regeneration process provides for substantial benefits to brewers through a reduction of costs to purchase and transport stabilization and clarification media, to dispose of spent cake and/or membrane retentate, while providing for substantial reductions in the introduction of soluble impurities into the fermented beverage.
