Patent No. 4277505A: Process For The Malting Of Grain

Today in 1981, US Patent 4277505 A was issued, an invention of Simon B. Simpson, for his “Process for the Malting of Grain.” Here’s the Abstract:

Germination of cereal grain in malting is carried out by passing steeped grain to and through a series of six closed spaced discrete vessels in succession. The grain is maintained in each vessel for about a day and in each vessel is subjected to an upward flow of humidified at temperated air. The grain is turned either in a vessel or through transference to the next vessel. Transference from one vessel to the other is carried out by discharging the grain from each vessel along a lower conveyor to an elevator which raises the grain to an upper conveyor that discharges the grain down into the next vessel. Grain leaves the last vessel of the series as green malt and then passes to a malt kiln where it is dried to a desired moisture level.


Patent No. 3589270A: Device For Preparing Brewing Malt

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. 606586A: Malt Stirrer

Today in 1898, US Patent 606586 A was issued, an invention of Jules Alphonse Saladin, for his “Malt Stirrer.” There’s no Abstract, although in the description it includes this summary:

It is my purpose to provide improved mechanism for propelling the turning-over carriage in both directions, for raising and lowering the spiral shovels at the end of each movement of the carriage and before beginning the next movement, and for initiating and terminating those operations of the mechanism which are automatic.

It is my purpose also to improve the construction, arrangement, and operation of the gearing and of those parts which mesh and unmesh the same at different points in the operation of the turning-over mechanism.

Patent No. 2245650A: Grain Separating Machine

Today in 1941, US Patent 2245650 A was issued, an invention of Ovie N. Christopherson, for his “Grain Separating Machine.” There’s no Abstract, but it’s described generally as and “invention provid[ing] an improved highly efficient machine for the separation of various grains or seeds according to their thickness or transverse diameter,” making two claims:

1. In a separating machine, a separating screen, means for simultaneously imparting to said screen endwise reciprocating and transverse movements, said screen having elongated slots extended in the direction of its longitudinal reciprocating movement, the transverse movement thereof :being crosswise of the direction of said slots.

2. The structure defined in claim 1 in which said screen is in the form of a rotary drum and the transverse movement thereof being in a constant direction.


Patent No. 3450600A: Malting Apparatus In Series

Today in 1969, US Patent 3450600 A was issued, an invention of James Richard Allan Pollack, Alan Aldred Pool, and Graham John Ellis, assigned to Arthur Guinness Sons & Co. Dublin, The Irish Mallsters Association, and Rimer Mfg. Co. Ltd., for their “Malting Apparatus In Series.” There’s no Abstract, although in the description it includes this summary:

[This invention is an] Apparatus for malting steeped cereal grain comprising two vessels one of which is a malting vessel and the other a storage vessel. The internal surface of the malting vessel converges downwardly toward the outlet. Sweeper means within the malting vessel is gyrationally mounted adjacent the outlet, grain engaging means provided on the sweeper, and the sweeper is adapted to sweep over substantially the whole area of the convergent surface for loosening the grain to be discharged. Means associated with the malting vessel for adjusting temperature, humidity, and rate of air flow therein to condition the cereal grain. First transfer means for conveying grain discharged from the malting vessel to the storage vessel. Second transfer means associated with the storage vessel for returning to the inlet means of the malting vessel grain discharged from the storage vessel.

Patent No. 650377A: Malting-Drum

Today in 1900, US Patent 650377 A was issued, an invention of John F. Dornfeld, for his “Malting-Drum.” There’s no Abstract, though it’s described this way in the application:

The primary object of the invention is to provide, in a malting-drum, an improved construction for positively stirring the steeped barley contained in the drum, whereby the contents of the drum are properly stirred and mixed at all times.

A further object is to provide an improved means for introducing water into the malt whenever necessary in an even and regular quantity and in such manner that the water is thoroughly mixed with the malt.


Beer Birthday: Sabine Weyermann

Today is the 57th birthday of Sabine Weyermann, co-owner of Weyermann Malting in Bamberg, Germany. If you’ve visited any of the Craft Brewers Conferences, you’ve no doubt seen the bright yellow and red of the specialty malting company, which is sold in the U.S. by the Brewers Supply Group. Sabine’s family began the Weyermann Malt company in 1879, although she can trace her family back at least as far as 1510. She’s an amazing person, and her malt has helped fuel many a small and large brewery. Join me in wishing Sabine a very happy birthday.

Patent No. 3796143A: Device For The Germination And Drying Of Malt

Today in 1974, US Patent 3796143 A was issued, an invention of Gisbert Schlimme and Manfred Tschirner, for his “Device for the Germination and Drying of Malt.” Here’s the Abstract:

A device for the germination and drying of malt charged onto the radially outer portion of an annular rotating rack and gradually shifted radially inwardly by means of rotary worm means extending radially across said annular rack and being suspended by threaded spindles for movement downwardly and upwardly between charge and discharge openings in an outer wall surrounding said annular rack.


Patent No. 3647473A: Malting Grain

Today in 1972, US Patent 3647473 A was issued, an invention of Peter Michael Howlett, and Keith Christopher Stowell, for their “Malting Grain.” Here’s the Abstract:

A process and apparatus for dehusking cereal grain by a dry mechanical method at a temperature not above about 105 DEG F., and wherein the moisture content of the grain is above about 8 percent by weight in order to damage the grain so that substantial rootlet growth is prevented without substantially damaging the aleurone layer. The dehusked grain is subsequently malted and there are advantages compared with conventional malting of husked grain.


Patent No. 6100447A: Method Of Barley Transformation

Today in 2000, US Patent 6100447 A was issued, an invention of Liying Wu and Raymond L. Rodriguez, for their “Method of Barley Transformation.” Here’s the Abstract:

A method for stably transforming barley from mature barley seeds as starting material is disclosed. The method involves germinating mature barley seeds until early shoot development occurs, exposing scutellar or embryo tissue cells on the embryo side of germinated seeds, and introducing foreign DNA into the cells. The cells are initially grown under conditions that allow expression of a selectable marker introduced with the foreign DNA, then on a callus-growth medium effective to suppress callus formation in the absence of the selectable marker. Successfully transformed calli can be cultured in suspension to obtain a desired foreign protein, or regenerated into plants, to obtain the foreign protein from the transformed plants, e.g., germinated seeds.
