Patent No. 1800632A: Method Of Preparing Hop Extract And Products Containing Hop Extract

patent-logo
Today in 1931, US Patent 1800632 A was issued, an invention of Emil C. Horst, for his “Method Of Preparing Hop Extract And Products Containing Hop Extract.” There’s no Abstract, but the description says simply it’s an “invention [that] relates to a method of preparing hop extract and the product obtained, the object being to obtain a hop extract containing all the desired constituents of hops of value for the manufacture of non-prohibited cereal beverages and other non-prohibited products.” And here’s how he summarizes it:

The method briefly stated consists first in extracting the volatile matter or oil from the fresh or dried hops. Secondly to extract the bitter constituents consisting of soft resins, the tannins, the coloring matter and the foam producing constituents, and third to combine the volatile oil of the hops and the extract to obtain a product containing all the constituents of hops required for the brewing of cereal beverages.

Patent No. 1489442A: Process Of Making Duplicate Packages Of Hops

patent-logo
Today in 1924, US Patent 1489442 A was issued, an invention of John W. Kauffmann, for his “Process of Making Duplicate Packages of Hops.” There’s no Abstract, but in the description it’s stated that he’s “invented new and useful Improvements in Processes of Making Duplicate Packages of Hops, which has for its object to render the process, more expeditions and considerably cheaper than has heretofore been done.” More specifically:

In making a large number of hop packages of equal weight, it is; necessary to open’ a bale of pressed hops, to take a given quantity, by weight, therefrom, to subject said quantity to pressure, and then to separate the unit obtained thereby into a plurality. of units, each of which is placed into a container, and this has hitherto been effected by subjecting the hops after the removal thereof from the bale to a considerably greater pressure than tliez same are subjected In the process which I employ and seek to secure by these Letters Patent I do not have to subject the hops to any greater pressure than the same are subjected to in baling them, and I can make a large number of hop packages of equal weight and size a single operation of the process. In carrying out this process I make a machine which is sufficiently illustrated in the drawing accompanying and forming a part hereof to enable a description of the process which is herein set forth to be understood by one skilled in the art.

Patent No. 1092538A: Beer And Hops Separator

patent-logo
Today in 1914, US Patent 1092538 A was issued, an invention of George F. Rauch, for his “Beer and Hops Separator.” There’s no Abstract, but here’s how it’s described. “This invention relates to the art of brewing, and particularly to a new and useful separator, for separating the beer and hops.” Apparently it has several features:

One of the features of the invention is the provision of a receptacle in which a revoluble pear-shaped screen is, mounted, having a distributor or splasher for swirling or splashing the fluid or combination of beer and hops against the inner circumference of the pear-shaped screen.

Another feature of the invention is the provision of a plurality of agitator wings carried by the distributer or splasher, which wings owing to the centrifugal force swing outwardly, so as to splash the fluid or combination of hops and beer against the inner circumference of the pear shaped revoluble screen, the beer passing through the perforations of the screen, while the hops pass centrally down through the screen.

Another feature of the invention is the provision of a stationaryv supported rake pear-shaped or conical screen, to prevent the hops from adhering or clinging to the inner circumference of the pear-shaped screen. In other words. the hops that may hang to the inner surface of the creen are raked or combed ofi as the screen revolves.

The beer that percolates through the perforations of the pear-shaped screen deposits and is carried oil by a spout. The hops pass centrally down through the screen.

Another feature of the invention is the provision of a conveyor disposed beneath the outlet of the screen to receive the hops, which are conveyed to and under a yieldably mounted pressure roller, so as to squeeze any further beer that may remain with the hops as they leave the screen.

Patent No. 4913680A: Low-Trellis Mobile Hop Picker

patent-logo
Today in 1990, US Patent 4913680 A was issued, an invention of Donald A. Desmarais, for his “Low-Trellis Mobile Hop Picker.” Here’s the Abstract:

A mobile hop picking machine is provided with independently elevatable wheels. The picker straddles a trellis to position opposing picking cats on either side of the vines. Front and rear banks of picking hooks move upwardly to pick the hops. A bank of resilient raking tines comb the vines upwardly between the picking banks. The picking cats are pivoted about their front edges and are supported for transverse movement on their rear edges. Cylinders urge the rear of the cats toward the vines. A contact member connected to the cat moves the cat transversely, to avoid cat contact with poles, against a biased mounting provided for the hydraulic cylinder. Longitudinal conveyors transport the hops rearwardly and upwardly. A squeeze conveyor floats on a top support over the elevating end of the longitudinal conveyors. An alternate arrangement intersperses the raking tines and picking hooks.

Crosby Hop Farms

crosby-hops
With the Craft Brewers Conference in Portland just a couple of weeks away, I’ve been receiving numerous e-mails from vendors who will be at the trade show. It happens every year. Some are of no interest whatsoever, while others are fun to see. For example, this morning one came in from Crosby Hop Farms, an Oregon hop grower. They’re doing an open house Wednesday night at the farm, which could be fun. But the e-mail included a link to a video they created about their company. No matter how many times I visit a hop farm, it’s always a spectacular sight.

This is the next best thing to being there. I think I may have to go to this one. You can also see more about the farm at Craft Brewing Business with these two stories: Hip hops: Craft beer’s impact on a growing industry and A Hop Farmer’s Diary: 30 days in the life of Oregon’s Crosby Hop Farm.

Patent No. 3436319A: Thin Layer Steam Distillation Of Hop Oil Extract

patent-logo
Today in 1969, US Patent 3436319 A was issued, an invention of Louis Anton Freiherr Von Horst and Maximilian Kellner, for their “Thin Layer Steam Distillation of Hop Oil Extract.” There’s no Abstract, but it’s described as relating “to a process of producing essential oil of hop preparations, and more particularly to a continuous process of producing such oil of hop, and to products obtained thereby,” with something approximating an abstract:

Improved process of recovering oil of hop from a solvent extract of hops by steam distillation in a novel manner, namely by passing the hop extract downwardly in a thin layer along an externally heated surface counter currently to the upwardly flowing steam in an oxygen-free atmosphere. This process has the advantage of completely recovering the oil of hop from the steam distillate and simultaneously producing a residual hop extract containing other components of said extract in substantially unaltered form. If the temperature of the starting solvent extract of hops is between about 80 C. and about 135 C., partial isomerization of the humulones to the isohumulones which are important brewing additives, takes place.

Save The Bees, Save The Beer

bee
Beer, of course, is an agricultural product, two of its main ingredients are very dependent on a good harvest. Both hops and barley (and other grains such as wheat and rye) grow best when they’re planted in the right place and the conditions are present to encourage their best selves. I received an e-mail a few days ago with the intriguing message. “Bees pollinate 1/3 of our food, including the hops used to make beer. Save the bees, save the beer.”

beer-and-bees

The e-mail was about an Indiegogo campaign to create a “community open to anyone who cares about bees, the environment and food,” called BeeWithMe, which will consist of “a dynamic new website that teaches people how easy and fun it is to raise a diverse range of gentle bees.” Unless you’ve been cryogenically frozen recently, you no doubt have heard that bees are disappearing from our environment, which could have devastating consequences for our food supply and our life cycle more generally. Find out how to participate at You Can Help Save the Bees, which begins:

Imagine a world without bees. There would be no blueberries, no cherries, no pumpkins – not even beer.

Here’s the problem: Most farmers depend on a single type of bee to pollinate our food and that bee, the honey bee, has been struggling.

You can be part of the solution and protect our food supply by raising gentle, native bees in your backyard or supporting someone else who does.

Keep your favorite foods on the table by contributing today and joining the BeeWithMe network that will collaborate to raise more native bees and grow more food.

Most of the pledge levels involve getting your own bees, some to simply release in your back yard, up to everything you need to raise your own bees. There are also teacher’s packages for classrooms and levels for entire garden clubs and communities. Please bee generous. And remember, save the bees, save the beer.
