Today in 1947, US Patent 2414669 A was issued, an invention of Gustave T. Reich, for his “Art of Brewing.” There’s no Abstract, but the description explains that the “invention relates to a continuous process of brewing beer from malt and cereal. Among its objectives are the securing of the maximum diastatic action in the minimum time thus permitting advantageous continuous saccharincation, the preventing of the destruction of the diastase and peptase by heat prior to the sacchariflcation of the mash so that the full effect of all the diastase is released in the sacoharifying step, the effecting of the maximum digestion of the malt by the peptase largely prior to the saccharibody of the hulls is not fication, the avoiding of dissolving objectionable soluble materials found in the malt hulls by digesting the malt while the hulls are largely intact.”
