patent-logo
Today in 1969, US Patent 3453114 A was issued, an invention of Peter D. Bayne and John L. Pahlow, assigned to Schlitz Brewing Co., for their “Process of Brewing.” There’s no Abstract, although in the description it includes this summary:

This invention relates to a process of brewing and more particularly to a process and apparatus for reconstituting concentrated brewers wort.

The present invention is directed to a continuous, high capacity process for reconstituting concentrated wort. The wort is reconstituted without color gain, loss of hop bitter or alternation of flavor. According to the invention, concentrated wort at a temperature of from 60 to 120 F., but preferably under and having a solids content of 80% is continuously pumped from a storage tank and/ or shipping containers and passed 4into a mixing system. Deionized water, -or filtered mains water, depending upon the purity of the water, is introduced into a mixer at a constant flow rate and is mixed with the stream of concentrated wort to partially reconstitute or dilute the wort. In some cases, particularly in high capacity installations, a second mixer in series may be employed and -a second stream of either deionized water or filtered mains water is introduced into the second mixer down stream from the first mixer. This second or breakdown stream of water is continuously introduced at a variable flow rate and mixed with the partially reconstituted wort to complete the reconstitution to the fermentation gravity.

Patent No. 732350A: Brew-House-Apparatus Equipment

patent-logo
Today in 1903, US Patent 732350 A was issued, an invention of Max Henius, for his “Brew-House-Apparatus Equipment.” There’s no Abstract, although in the description it includes this summary:

My invention relates to an improvement in the equipment of apparatus employed in the department of a brewery known as the brewhouse, which is devoted to the operation of producing the wort by practicing the several generally-stated steps of making the mash, drawing off and hopping and boiling the resultant wort, separating the hopped wort from the hops, and finally cooling the hopped wort preparatory to pumping it into the fermentation-vat.

Hitherto the equipment employed in the manufacture of the wort in the brew-house has involved a multiplicity of apparatus, which has rendered not only the installation of the plant in the matter of building and apparatus but also the maintenance and operation very expensive.

The object of my improvement is to simplify the apparatus equipment for a brewhouse by reducing to the minimum the number of apparatuses for practicing the several necessary steps in wort manufacture by adapting a number of the comparatively few apparatuses provided to perform each several of the steps of the process Where hitherto a separate apparatus was in most or at least some instances required for the practice of each separate step.

Patent No. 3589270A: Device For Preparing Brewing Malt

patent-logo
Today in 1971, US Patent 3589270 A was issued, an invention of Gisbert Schlimme and Manfred Tschirner, for their “Device For Preparing Brewing Malt.” There’s no Abstract, although in the description it includes this summary:

A single apparatus for preparing brewing malt in three steps, namely steeping, germinating and drying. A horizontal rotary annular perforated rack arranged in a cylindrical trough is charged with the material to be treated and while placed on the rotating rack is firstly steeped in water introduced into the trough below the rack. After the water has been discharged, the germinating step is performed by introducing air conveyed by a fan into the space between the rack and the bottom of the trough and upwardly through the material, which latter is turned by a horizontal series of vertically arranged turning worms which as a unit may be horizontally moved into the material on the rotating rack, the’ unit of worms being vertically movable into the layer of material and again outwardly therefrom.

During the final drying step, the same fan is used to circulate heated air through the material on the rotating rack, and the dried material then discharged from the rack by a conveyor which may be lowered into the material on the rack. The material is then discharged into a worm conveyor leading to a discharge pipe. As conveyor may serve an endless conveyor with buckets which scoop the material from the rack.

Patent No. 229374A: Apparatus for Purifying Air

patent-logo
Today in 1880, US Patent 229374 A was issued, an invention of Friedrich A. Bruns, for his “Apparatus for Purifying Air.” There’s no Abstract, although in the description it includes this summary:

The object of this invention is to furnish means for cooling and purifying the atmospheric air which is required for handling beer, ale, wine, and other fermented liquors during fermentation. These liquids are at present transferred by means of air compressing pumps from one cask to another, the air employed for forcing the liquids carrying microscopic organisms and inorganic impurities which impregnate the beer or other liquid and exert an injurious influence thereon. To prevent these organisms from entering the liquids I employ a cooling and purifying apparatus, through which the air is drawn by the air-pump, so that all inorganic and organic impurities are retained and destroyed, and thereby a perfectly pure air supplied for handling the liquids. Fermented liquors treated with air purified in such a manner keep better, become perfectly clear, and are not liable to deterioration.

My invention consists more especially of a cooling-chamber filled with ice and provided with a top screen covered with a layer of cotton or similar material, and of an acid-chamber, into which the air is drawn from the cooling chamber and minutely divided therein by a perforated distributer and screen, to be then conducted off for use. Referring to the drawings, A represents a cooling-chamber, which is filled with ice and provided at the bottom with a discharge pipe for the ice water and with a suitable water-seal.
