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.

Patent No. 2121458A: Apparatus And Process For Aerating Wort In Yeast Production

patent-logo
Today in 1933, US Patent 2121458 A was issued, an invention of Wilhelm Vogelbuseh, for his “Apparatus And Process for Aerating Wort in Yeast Production.” There’s no Abstract, although in the description it includes this summary:

In the production of yeast, air is supplied to the wort during the fermentation in order to meet the oxygen requirements of the multiplying cells and also to render harmless the interchange products which are produced. Hitherto, compressed air from an air pump has usually been introduced into the wort through a rigidly mounted tube system which is placed horizontally at the bottom of the fermenting vat and the separate tubes of which are provided with holes. The attempts in recent years to reduce the size of the air bubbles have led to the diameter of the air outlet holes being reduced down to 0.3 mm. On account of the danger of stoppage and the difficulty of keep through such holes. Distributing devices provided with tubes or boxes of burnt clay, stoneware, sintered glass, etc. to act as air outlet surfaces have been used. The saving in power, however, does not correspond to the reduction of the amount of air as these materials, on account of their smaller permeability, require a higher operating pressure. keep such a body perfectly clean as is required for avoiding contamination.

The object of the invention is to avoid these disadvantages, and the invention consists in that a hollow body of suitable shape serving for delivery large openings and which, in the direction of movement, offers as little resistance as possible and allows the air to escape preferably in a direction different from the direction of movement and preferably at right angles or approximately at right angles thereto is moved through could hitherto only be obtained in the yeast industry by using the above-mentioned ceramic materials for the air supply member. In addition, it is difficult to ring the air into the liquid through comparative count of the above-mentioned disadvantages, have not become widely used.
