Patent No. 513694A: Apparatus For Drying Barley, Malt, Etc.

patent-logo
Today in 1894, US Patent 513694 A was issued, an invention of James White, for his “Apparatus For Drying Barley, Malt, Etc.” There’s no Abstract, although in the description it includes this summary:

My invention has reference to apparatus for drying barley, malt, oats, wheat or other substances of a granular or pulverulent nature.

The invention mainly consists in the construction within a kiln or drying house of an inclined or vertical channel formed with foraminous sides and divided transversely at suitable intervals into chambers the bottoms of which contain cross passages, which passages When the barley or other material which is supplied to the upper end of said channel is allowed to run or flow from one chamber to that next below, transfer the material that was at and near the respective sides of the upper of the two chambers to the opposite sides of the lower chamber, whereby the material gets well mixed and turned over and is consequently more uniformly dried than if it were merely allowed to slide bodily from chamber to chamber.

The invention further consists in the combination with the said cross passages at bottom of each compartment of a central tongue or board projecting up from between said cross passages, and of a central tongue or board projecting down from between said cross passages, the said tongues serving as guides or dividers for the material as it respectively enters and leaves said passages. The lowest chamber does not require cross passages at bottom but has a slide or shutter at top and another slide or shutter at bottom.- When the apparatus is inoperative the bottom slide is normally kept closed and the upper one open, and the two slides are worked at intervals to allow the material in the several chambers to move down one stage, that is to say to the extent of one chamber. To effect this the upper slide is first closed and the bottom slide is then opened to allow the lowest chamber to empty itself into a chute or receptacle. The bottom slide is then closed and the top slide opened, when every chamber (except the lowest) will empty itself through the cross passages into the chamber next below and become filled from the chamber next above, the top chamber receiving its supply from a hopper or otherwise.

Today in 1999, US Patent 2295931 A1 was issued, an invention of Makoto Kihara, Takafumi Kaneko, Kensuke Fukuda, and Kazutoshi Ito, assigned to Sapporo Breweries Ltd., for their “A Method For Identifying a Barley Variety and a Barley Having a Brewing Property.” Here’s the Abstract:

A method for identifying barley with good brewing properties using the thermostability of the barley .beta.-amylase as an indicator. The thermostability of the barley .beta.-amylase significantly affects the degree of the apparent attenuation limit. A method for determining the enzyme activity of an extract solution from one barley seed, an indirect method by an isoelectric point, and an indirect identifying method by DNA polymorphisms of the region containing the .beta.-amylase structural gene have been developed as a method for determining the type of thermostability for a barley .beta.-amylase. The selection method is not affected by environmental or climatic conditions.

Patent No. 3840435A: Malting Apparatus

patent-logo
Today in 1974, US Patent 3840435 A was issued, an invention of Rees Damon, assigned to Rahr Malting Co., for his “Malting Apparatus.” There’s no Abstract, although in the description it includes this summary:

Apparatus for malting barley including an elongated germination compartment and a plurality of vertically extending, transversely spaced augers moveable longitudinally within the compartment for intermittently mixing the barley during the germination period. To remove the malted barley from the germination compartment, the compartment floor includes a centrally positioned, longitudinally extending opening. A plurality of longitudinally spaced pairs of gates are pivotably mounted within the floor opening; the gates comprising each pair are pivotally attached to opposite edges of the opening for pivotal movement between a generally horizontal floor-forming position closing the opening and a downwardly inclined position allowing the malt within the compartment to pass through the opening to suitable means (e.-g. a conveyor) for transporting the malt to a drying kiln. A transversely extending auger is removeably mounted immediately behind the vertically extending augers and adjacent the compartment floor for moving the barley transversely within the germination compartment toward the centrally positioned floor opening during the compartment unloading operation. Pneumatic switches are positioned along the side of the germination compartment to automatically and independently pivot (i.e., open) the floor gates at successive predetermined positions of the transversely extending auger.

Patent No. 2998351A: Process For The Continuous Malting Of Grain

patent-logo
Today in 1961, US Patent 2998351 A was issued, an invention of Noel Keir, Frederick Richard Graesser, Wilbert E. Stoddart and Douglas L. Thompson, assigned to Dominion Malting Ontario Ltd., for their “Process for the Continuous Malting of Grain.” There’s no Abstract, although in the description it includes this summary:

The present invention avoids most of the disadvantages of the prior art and provides for simple continuous processing through which not only complication is avoided but the processing may be reduced to a period of three days or less in comparison with approximately ten days or more, and is subject to minute control which has been difficult in prior batch processes. In fact the present continuous process provides for continuous processing through stages or zones maintaining constant conditions, varied as to one another, according to requirements necessary in regard to the character of the grain, and through which the grain continuously passes in effect to provide the continuous yield of a substantially uniform malt. Moreover, other attendant advantages result as labour required per unit of production will be reduced, resulting in greater economy, the weight and strength of complete equipment will be reduced and initial costs of buildings thus lessened; whereas the process provides for an extremely wide range of control as to time and processing, moisture content and temperature gradient, so that the conditions of manufacture may be adapted to the quality and type of grain being processed as to provide for the production of malt of superior quality and of generally uniform character in which all factors of production have been closely controlled throughout.

The invention generally embodies the steps of continuously forming and moving a bed of grain in a predetermined path, subjecting said moving grain bed to intermittent periods of water spray and periods of rest and periods of humid aeration at temperatures between 50 and 100 F., and finally moving said bed through a drying zone at elevated temperatures. Preferably the processing includes in said steps a period of drenching the bed followed by dry aeration. The grain may be introduced to the processing steps in any suitable manner, such as by pumping it together with water to the point of preliminary processing, which may start with the dispersing of the grain in water, and allowing the sound grain to settle, while the lighter grain and low gravity extraneous material may be continuously removed from the surface of the water body in which it is dispersed and delivered to a suitable recovery unit.

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

patent-logo
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.
