Application filed February 20, 1899. Serial No. 706,111. (No model.)
To @ZZ whom t may concern:
Be it known that I, OTTO SELG, a citizen of the United States, and a resident of New York, (Brooklym) State of NewYork, haveinvented certain new and useful Improvements in M ashing Apparatus, of which the following is a specification.
This invention relates to a mashing apparatus used in brewing beer and similar beverages, which is so constructed that the entire contents ofthe tub are thoroughly actedupon by the liquids, steam, and compressed air introduced, and that more particularly the formationof a dead layer upon the bottom of the tub is avoided.
In the accompanying drawings, Figure 1 is a vertical longitudinal section of my improved mashing apparatus and Fig. 2 is ahoriZont-al section on line 2 2, Fig. l. n
The letter A represents the mash-tub, provided with a concave bottom a and a corresponding perforated false bottom a', adapted to concentrate the grain into a closely-packed body. The steam, thin mash, air, and water are adapted to be fed into the tub by two different pipes or pipe systems, the one entering through the bottom a and the other arranged within the body of the tub directly above the false bottom ct'. Thus in the drawings the main conduit-pipe b connects at the top with thesteam-pipe c, thin mash-pipe d, water-pipe e, and compressed-air pipe f, while at the bottom it divides into two branches g and h.
The branch g, controlled by cock g', is a circular pipe placed against the inner Wall of `tub A directly above the false bottom a. It
has a number of downwardly-opening perforations g2, through which the contents of the pipe are blown from above into the lower stratum of the mash supported upon the false bottom, so as to thoroughly penetrate the same.
enters the central opening c2 of the bottom a above the discharge-gate a3 and blows the contents of the pipe into the mash from be-v low. Thus by means of the combined action of the branches g h the malt is thoroughly The branch h, controlled by cock h acted upon by the steam, compressed air, and liquids introduced, and the settlement upon the false bottom of a body of malt which is not thoroughly worked up and saturated is avoided. l
` The stirrer is composed of a number of obliquely-set blades 'i i', secured to opposite ends of a series of arms 2, mounted upon the power-shaft 713. The blades connect adjoining pairs of arms 'i2 at one end, while the blades i' connect the intermediate pair at the opposite end, so that in this way an opening is formed at the ends of the arms between each adjoining set of blades. This peculiar construction of the stirrer enables it to freely enter the mash and agitate the same in a very perfect manner.
The arms i2 increase in length from the periphery toward the center of the tub A, and the blades t' t" are curved-to conform to the curvature of the falsebottom a', so that they may sweep freely over such bottom.
As the tube g is located above the false bottom,it is clear that the malt supported upon the latter is thoroughly agitated and washed out, so that all the extract is effectively withdrawn. Moreover, by admitting steam,hot water, or air to the tub simultaneously from its inner and its outer side the mash becomes thoroughly and uniformly impregnated throughout its body, so that a superior wort is obtained.
In a mashing apparatus, the combination of a mash-tub having a curved bottom and a perforated curved false bottom, Witha circular inner vperforated tube above the false bottom, an outer tube opening into the tubbottom, and means for feeding liquids, steam or compressed air into said tubes, substantially as speciied.
Signed by me, at New York city,New York, this 18th day of February, 1899.
