By

patent-logo
Today in 1950, US Patent 2529882 A was issued, an invention of Carl F. Mittman, for his “Hop Strainer.” There’s no Abstract, although in the description it includes this summary:

This invention relates to strainers, clarifiers and. filters, and more particularly to a combined hop strainer and trub clarifier or separator for use in the brewing industry.

An object of this invention is to provide an improved strainer, clarifier and separator with which the cooked hops and wort may be separated continuously, completely and rapidly; with which a major amount of the trub, that is, the fine solids of the cooked hops and wort mixture, will be effectively separated from the wort; with which no sugar coating on the separating surface can take place; with which the separating surfaces will be automatically cleaned; with which all parts of the apparatus Will be easily accessible for cleaning and collection of stale wort is prevented; which will have maximum capacity with minimum overall dimensions and low cost of operation; and which will be relatively simple, compact, efficient, practical and inexpensive.

Another object of the invention is to provide an improved simple, inexpensive and continuous method of separating cooked hops and wort; with which maximum recovery of the wort is .possible; and which will require only relatively simple apparatus.

Another object is to provide an improved method and apparatus for continuously separating cooked hops from wort; with which the separation Will occur upon a clean and sterile screen; with which the screen will be conditioned continuously and automatically during use.

Patent No. 2181931A: Process For Extracting The Essential Principles Of Hops

By

Today in 1939, US Patent 2181931 A was issued, an invention of Lyndon D. Wood, assigned to National Hops Lab, Inc., for his “Process for Extracting the Essential Principles of Hops.” There’s no Abstract, although in the description it includes this summary:

My process is essentially as follows:

My first procedure is to suitably prepare the hops by pulverizing them to’ a degree of fineness sufficient to crush all of the seeds which they contain and finely enough so that they will pass a 20 mesh screen or sieve. This may be done in any one of several types of mills which can be adapted for the work such as a ball mill, plate mill, roller mill, or a cutting mill, or a combination of cutting and hammer mill. The mill should be enclosed so that no air current are present in which the aroma of the hops can be dispersed. From the mill the prepared or pulverized hops should be conveyed to a closed tank or receptacle where the solvent is applied.

When old hops are used in which the lupulin has hardened and particularly those in which a rancid odor has occurred from the oxidation of hop oil, I employ activated carbon, which may be made from the vegetable, fibrous material of the hops residue after extraction has been made.

This activated carbon may be used in two ways. (a) By mixing it in finely powdered form with the pulverized hops while they are in a dry state.

When this method is employed ounce of activated carbon will be used to each pound of pulverized hops. The prepared hops should be stirred and shaken until the activated carbon has been thoroughly mixed with them, then be permitted to stand in a closed container for a period of time not less than two hours. The activated carbon experiments have shown restores the odor of fresh hops.

Beer In Ads #1749: Putting A Schooner In A Bottle Is Skilled Work

By


Friday’s ad is for Oland’s Schooner Lager Beer, from 1967. The Oland Brewery is from Nova Scotia, Canada, though today it’s owned by Labatt Brewing, and ultimately ABI. The tagline, “putting a Schooner in a bottle is skilled work,” plays nicely on the beer’s name and follows through with the punchline at the bottom, “taking it out is pure pleasure.”

Patent No. 3776260A: Beer Kegs And Like Containers

By

patent-logo
Today in 1973, US Patent 3776260 A was issued, an invention of Maurice Ruddick, for his “Beer Kegs and Like Containers.” Here’s the Abstract:

A spear and closure assembly which is arranged to be fitted as a single unit in the neck of a beer keg or like container comprises a tubular housing having one end open and the spear fixed to the housing and projecting from its other end, and a valve seat which is fixed to the housing so that it is located adjacent the open end of the housing and projects radially inwards with respect to the open end. The housing, the spear, and the valve seat are connected to form a unitary structure, such as by welding or by a combination of welding and being formed integrally. A spring located within the housing acts on a disc like closure member so that a resilient valve ring is pressed by the closure member against the valve seat, hence closing the opening bounded by the valve seat. Assembly of the spring, the closure member, and the valve ring within the structure is made easy by arranging that the size and shape of the spring and closure member allow these to be passed through the opening bounded by the valve seat, and by providing the valve ring with sufficient resilience to allow it to be deformed and squeezed through this opening. In use, application of a filling or dispensing fitting moves the valve ring and the closure member axially inwards against the action of the spring, the valve ring being displaced axially relative to the closure member and forming a seal against a second valve seat formed on the housing so that two separate passages are formed through the fitting and into the container, one through the housing and the spear and the other outside the housing via an aperture between the two valve seats.

Today in 2001, US Patent 6326185 B1 was issued, an invention of Michael C. Barney, Kathleen M. Carrick, Alfonso Navarro, and David S. Ryder, assigned to Miller Brewing Company, for their “Method For Decontaminating Yeast.” Here’s the Abstract:

An improved method for reducing colony forming units bacteria in yeast is disclosed. The method involves contacting the yeast with a hop acid in an amount sufficient to give a final concentration of the hop acid of at least about 40 ppm.

Patent No. 2772975A: Injecting Of Hops In The Brewing Of Beer

By

patent-logo
Today in 1956, US Patent 2772975 A was issued, an invention of Frank Otto Rickers, assigned to the Geo Wiedemann Brewing Co. Inc., for his “Injecting Of Hops In The Brewing Of Beer.” There’s no Abstract, although in the description it includes this summary:

It is an object of the present invention to provide for the addition of the hops to a brew kettle in a manner such that the hops will be uniformly distributed through the brew and for greatly increased control over this step of the brewing so any deteriorating effect is prevented by storing in cold temperature so that the loss of hops up the flue will be minimized. Thus, it is an object of the present invention to provide process to the end that each successive brew will have undergone the same length of time in the cooking of the same amount of hops.

Briefly, in the practice of my invention I provide means for insuring that the hops, as they are added to the kettle, are wetted down and caused to enter below the surface of the brew in a rather closely confined area and I provide for a localized ebullition and circulation of the brew such that the lumps or fragments of hops are carried by this localized ebullition and circulation down into the bottom of the kettle whence they are uniformly distributed by the general circulation in the kettle.
