Patent No. 2138529A: Hop Separator

By

patent-logo
Today in 1938, US Patent 2138529 A was issued, an invention of Edouard Thys, for his “Hop Separator.” There’s no Abstract, although in the description it includes this summary:

This invention relates to separators and especially to a machine for separating leaves and like foreign material from hops, the present application being a continuation in part of my co-pending application entitled Hop picking machine, filed November 13, 1935, Serial Number 49,531.

The picking of hops by means of machinery is now a comparatively old art as machine picking has been in continuous use on a comparatively a large scale in California and other States at least since 1910. The type of machine generally employed consists of a series of revolving drums from the surface of which project V-shaped flexible wire fingers. The vines to be picked are l passed over and under the drums by a conveyor and as the vines pass over and under the drums they are combed by the V-shaped fingers and the hops are removed during the combing operation. A great many leaves and stems are also m removed and some of the hops are broken, thereby forming petals, hence after the picking operation has been completed it becomes necessary’ to separate the hops from the leaves, petals and stems as the cleaner the hops the higher the market value of the same.

The present invention relates. to a machine for separating the hops from the leaves, petals, stems, etc., the object being to improve and simplify the separation of hops of this character; to provide a pervious inclined belt upon which the hops, leaves, etc., are delivered; to provide means in the form of fans, or the like, placed under the belt so as to maintain a sufficient suction to cause the. lighter material, such as leaves, petals, etc., to adhere to the surface of the belt while the inclination of the belt will permit the hops to roll down and off the belt; to arrange the belt in such a manner that the air blast produced by the discharge side of the fans may be utilized to release the leaves, petals, etc., from the belt; and, further, to provide means for adjusting the inclination of the belt to insure rolling and gravity separation of the hops from the leaves and other organic matter.

Patent No. 2530594A: Separating Solid Matter From Hot Wort

By

patent-logo
Today in 1950, US Patent 2530594 A was issued, an invention of Fremont W. Benedict, for his “Separating Solid Matter From Hot Wort.” There’s no Abstract, although in the description it includes this summary:

The present, invention aims to effect air separation from the hot wort of most of the nitrogenous substances, and hop resins prior to the delivery of the wort to the coolers and starters. The method of the invention involves introducing the hot wortl into a charging zone where the wort is under some turbulence and from whence it flows into an adjacent and substantially larger quiescent zone. The communication between the two zones is well below the liquid level; and substantially clear wort is withdrawn from the quiescent zone near the liquid level and at a point as remote as practical from the charging zone. The apparatus of the invention comprises a tank of any desired configuration having a partition dividing the tank into a charging or feeding compartment and a’ settling compartment of considerably larger volume than the charging compartment. The lower end of the partition is spaced a short distance above the bottom of the tank, and the space between the partition and the tank bottom provides the communication between the two compartments. The hot wort is preferably delivered in a stream above the. liquid level, so that it splashes into the wort in the charging compartment and keeps the wort there in agitation. A float-controlled discharge is provided for withdrawing substantially clear wort from near the liquid level “of the-settling compartment at a point remote from the partition.

Patent No. 4483881A: Process For Discontinuous Wort Boiling During Beer Manufacture

By

patent-logo
Today in 1984, US Patent 4483881 A was issued, an invention of Bernhard Lenz, for his “Process For Discontinuous Wort Boiling During Beer Manufacture.” Here’s the Abstract:

In discontinuous wort boiling for the manufacture of beer, the energy of the vapor arising from the boiling is used in a heat exchanger for the production of hot water. The heated brewing water is reheated in a second heat exchange process by the energy from the vapor arising from the boiling and, with this reheated brewing water, the refined wort is heated again in another heat exchange process before the boiling, whereby the brewing water which is cooled in this heat exchange process is reheated by the energy from the vapor arising from the boiling. Thus, the energy from the vapor produced during the wort boiling is fed directly back into the wort boiling process.
