IMPERIAL

PATENT OFFICE.

The present invention relates to a novel mash vessel that his Purposes accordingly in the previous form under the name Maischbottich very special is used for brewery and distillery purposes. The usual shape of a mash tun has a bottom opening Emptying the wort on and is also provided with a colander and a stirrer. Although this type of mash tun to a certain extent the use the same as a reversible mash vessel and as a separation device for the wort possible, it has major disadvantages, since the colander is always the bottom part of the vessel forms, and is thus often clogged in many places during the mash operation, whereby the emptying of the wort is impure and time consuming.

The mash tun forming the subject of the present invention enables the arrangement of the colander in such a way that the latter in the upper parts during the mashing operation of the main vessel and turned downwards to empty the wort , whereby the above-mentioned inconveniences are avoided.

An advantageous embodiment of this apparatus is shown in the drawings.

Fig. Ι is a vertical longitudinal section through the apparatus, and

Fig. 2 is a cross section according to Fig. 2-2 of Fig. 1 on an enlarged scale.

A is the main vessel, which advantageously has a cylindrical shape and is provided with an opening a ; the latter is covered by a removable colander B. This vessel A is surrounded by a steam jacket b and this is equipped with inflow and outflow b ^l (FIG. 2) and b ' ² (FIG. 1). C is the stirrer; it consists of a hollow shaft c mounted in opposite ends of the vessel, which, if desired, is formed from parts coupled to one another and provided with stirring blades c ^2. The blades c ^1, to the tubular, advantageously below 120 ⁰ staggered arms c ¹ of the shaft mounted c, and each arm of a group is provided at its end with an at d indicated in the drawing, non-return valve, while the remaining arms are closed. Opposite the opening α of the vessel there is an opening a ^l which passes through the steam jacket b and is closed with a screw ^{plug a 2} α ³ . The agitator shaft c itself is sealed by a stuffing box e and carries a drive disk f at its end; the outer end of this shaft serves to receive a tube g ^{sealed by a stuffing box e 1} for "water supply through a shut-off element h and for the introduction of steam through a branch pipe g ¹ and a shut-off element h ¹ , with a pressure gauge D also being arranged." The vessel itself is rotatably mounted in a bracket E on rollers i , the latter being intended to run on a running ring k.

The ring / carries a ring gear m, which can be rotated from a pinion η seated on a shaft n ^l (FIG. 2).

It is desirable that the colander B be removable for the purpose of filling the vessel. is. For this purpose, this colander is attached to the bottom of a frame 0, which ^{can be lifted by means of handle o 1} after loosening suitable side bolts. The races k and Z are divided at the points crossing the strainer, as can be seen from FIG.

When the mash vessel is in the position shown in FIG. 1, the mash is introduced through the opening α after removing the strainer and the agitator is put into operation. To keep the mash at a suitable temperature. obtained, steam is admitted through the pipe g , which flows into the vessel through the hollow stirrer shaft c and the valves d , while water can flow in through the pipe g after opening the tap h . Of course, it is not necessary for the supply of water and steam to be effected in the manner just described, since the temperature of the mash can also be kept high enough by the steam supplied into the jacket b. However, the present embodiment is particularly advantageous since the hollow design of the shaft and the agitator arms c ^{1 forms} the simplest solution to the problem on which this purpose is based.

After completion of the mashing operation and insertion of the strainer, the agitator is put out of operation and the gear η is put into operation in order to turn the vessel A in such a way that the strainer goes downwards and the opening a ¹ comes upwards. This opening is connected to a pipe F through which compressed air can be driven into the vessel A by means of a pipe provided with a valve ρ . The wort now flows through the colander and is collected in a suitable container for further processing. The compressed air flowing in through the pipe F serves to accelerate the separation of the wort from the mash.

After the wort has been separated, the vessel A is turned back to its normal position and the colander is lifted out, whereupon the vessel is turned again to tilt the rest of the mash and to clean the vessel itself using water introduced to absorb the hopped wort. For this purpose, the colander B is reinserted after turning the vessel back and after turning the colander downwards again, the wort mixed with hops is introduced through the pipe F and hopped.

It is easy to see that by this device of the mash tun according to the present Invention an advantageous operation and unimpeded emptying of the wort is possible, the processing of which with the previously known mashing devices is very cumbersome was.

Claims (2)

Patent Claims: 1. Process for the production and lautering of mash, in particular for brewery and distillery purposes, characterized by the use of a rotatable, with a stirrer and a possibly removable colander provided in such a way that the vessel is rotated so that the colander During mashing, the upper part is above the level of the mash, but during lautering it is at the bottom of the vessel. 2. An apparatus for carrying out the method according to claim 1, characterized by a cylindrical or other rotatable vessel, on the surface of which a sieve surface that can be appropriately lifted out is attached so that the straining surface is on top during mashing and during the separation of the Mash the wort below. 1 sheet of drawings.
