STEAM NIASHING APPARATUS FOR BREWERY PURPOSES.
SPECIFICATION forming part of Letters Patent No. 649,216, dated May 8, 1900'.
l Application filed .l'nly 12, 1899. Serial No. 723.551. (No model.)
To @ZZ whom t may concern:
Be it known that I, FRANZ SOHAEFER, engineer, a subject of the Emperor of Germany, residing at 104 Westwall, Orefeld, in the Kingdom of Prussia andgEmpire of Germany, have invented certain new and useful Improvements in Steam MashingApparatus for Brewery Purposes, of which the following is a full, clear, and exact description.
In practice special steam apparatus is used for steam mashing for brewery purposes, which as a rule consists of a system of tubes through which the steam is conducted, and in more modern plants these tubes are continuously rotated in the mash-tun.
2o movement of the mash in itself and relatively to the heating-surface. As a rule it is impracticable to employ Scrapers rotating in contact with the walls of the mash-tun, for the reason that they impede the rotation of the z5 steam-pipe system. The pipes must be arranged in some such manner as that shown in the German Patent No. 35,237, where they consist of bent U-shaped pieces which are fastened at intervals to hollow collars on a 3o solid axle passing centrally through the apparatus, which collars also serve to conduct the steam. This contrivance, however, has the disadvantage that the steam cannot pass unimpeded through the whole pipe syst-em,
3 5 but must at intervals return to the collars on the axle, which to some extent constitute the steamchest. The natural consequence of this is that the temperature is not the same in the last pipe as in the first, owing to the 4o repeated interruptions to the passage of the steam. A uniform working of the mash is therefore impossible. A further and greater disadvantage is that in steaming the mash in such an apparatus it frequently lies unstirred against the smooth wall of the rotating steamchest in consequence of the slight amount of friction, whereby the possibility occurs of the mash easily burning, owing to the heat generated in this place, and a uniform mashing 5o cannot take place, because there is much greater generation of heat in this place than at the periphery.
The object of the present invention is to obviatethese two great disadvantages as much as possible and is attained by passing the steam through a steam chest with double walls, forming chambers adapted to be illed with non-conducting material and asimilarly-constructed steam-pipe into the rotating pipes, which are arranged in such a serpentine manner as to form separate parallel planes.l At the same time an unbroken circulation of the steam through all the convolutions of the pipe system from top to bottom is insured. In an apparatus thus constructed the steam-pipe system can be made to rotate conveniently between the several Scrapers.
The improvement is illustrated in 'the accompanying drawings.
Figure 1 is a sectional elevation of a steam mashing apparatus embodying this improvement. Fig. 2 is a plan of the same, partly in horizontal section. Fig. 3 is a detail perspective v iew of one of the steam-coils hereinafter described.
Steam is supplied through a pipe a, connecting with an interior pipe a, forming part of the rotary apparatus and turning in a suitable stung-box s. The interior pipe a is surrounded by a second pipe b, which expands below into a dome-shaped covering for the steam-chest Z7'. The latter is also provided with a double wall b2, so that between this and the inner wall b3 an insulating-space f results. This insulating-space, as also that around the steam-pipe c', is in practice filled with some material calculated to impede heat radiation in order that theheat may be diminished on the outer surface of the rotary steamchest. Bythis means, the mash, which, as was pointed out in the introduction, receives little or no stirring movement in this place, is prevented from burning and uniform mashing is insured. The steam-chest is constructed with a top chamber bx, separated from the main body by a partition p. The steam-pipe a delivers into this top chamber 19X, and with it the first section c of the steam-coil c connects. The circulating steam passes out from the top chamber bX of the steam-chest into the rotating coil, which is arranged in a serpentine manner, so that the first coil-sections c', here shown four in number, extend radially outward, each connecting bya bend IOO with the second section c2, which extends in ward nearly to the center, where it is bent, and extends outward again in the second plane as the third pipe-section c3. In the same horizontal plane it turns inward again, is again led downward, and again outward as the coilsection c4, and backward as the last coil-section c5, which is connected with the steamchest b near its lower end. The inward and outward circulation pipe sections thus lie above each other. In this way the pipe-planes when rotated move between the ixed Scrapers g, prevent burning, and produce an intimate mixing, thus insuring a uniform mashing.
The whole apparatus, consisting of the steam-chest and pipe system, is set in motion by the band-pulley h, the shaft of which connects by bevelapinions 2 with the vertical axle m of the rotaryr steam-chest b. The lower journal end of the axle mis also made hollow, so that the steam may pass off through it and the pipe n.
The following is what I claim and desire to secure by Letters Patent:
l'. The steam mashing apparatus for brewing, constructed as herein described with a rotary steam-chest b surrounded by an outer wall b2 inclosing a chamber f to reduce conduction of heat and a steam-coil o connected with said steam-chest and formed of convolutions arranged radially in a number of parallel planes, in combination with fixed Scrapers g between which the radial arms of the steamcoil revolve, as explained.
2. The combination of the induction steampipe ct rotary steam-chest b inclosing walls b and b2 steam-coil c, consisting of a number of convolutions c c2 c3 c4 radially arranged in. parallel planes and communicating with the rotary steam-chest, hollow shaft m exit-pipe n and suitable Scrapers g between which the arms of the steam-coil revolve substantially as described.
In witness whereof I subscribe my signa LUDWIG SCHMELZ, E. WEICH.
