  • Process for the secondary purification and stabilization of liquids containing polyphenols and/or proteins, particularly beverages and more especially beer
    Patent number: 4910182
    Abstract: The present invention concerns a process for secondary purification and stabilization of liquids containing polyphenols and/or proteins. The liquid to be treated is first subjected to a centrifuge, or similar apparatus, which performs the primary purification of the liquid. The treated liquid is then mixed with stabilizing means that adsorb the polyphenols and proteins and filter means that retain the fine turbidities contained within the liquid. The liquid mixture is then transferred to an alluvial filter apparatus in laminar flow wherein the filter means and stabilization means along with the adsorbed polyphenols and proteins form a filter cake. The purified liquid is then transported to subsequent treatment while the filter cake is subsequently treated with a solution which dissolves the polyphenols and protein thereby regenerating the stabilization means and the filter means.
    Type: Grant

  • Method and apparatus for stabilizing wine or other beverages
    Patent number: 4322446
    Abstract: A method for stabilizing of wine or other tartaric acid containing beverages. Separation of dissolved wine lees (tartar and/or calcium tartrate) from the beverage is effected by passing the beverage through a deposit or settling layer containing tartar crystals and/or calcium crystals. The disclosure for carrying out the method includes a heat exchanger, a cooler, a dosing container, a stabilizing unit, and a sheet filter. The stabilizing unit has several filter elements arranged one above the other and spaced with respect to each other.
