Description

The invention relates to a device according to the preamble of the patent claim.

In the device according to the main patent, the water is in the form of one or more contiguous Water films introduced into the mash in a very even, fine distribution, with only one minimal mixing of air into the water takes place.

In the embodiments described in the main patent, the water is preferably in the form of water films running parallel to the nip rollers, in particular when using the parallel to The side walls of the housing running along the squeeze rollers as guide surfaces are introduced into the machine.

The invention is now based on the object of further developing the device according to the main patent in such a way that that material accumulations and caking on the housing walls above the mash level be avoided.

According to the invention, this object is achieved by the characterizing features of the patent claim solved.

Accumulations of material that form in the area of the end walls are caused by the in the area of these Front walls created water film dissolved immediately and entered into the mash. This is how im A film of water is generated on all four sides of the housing chamber, so not only does the water get in very fine distribution and without significant mixing of air into the mash, but rather there will be at the same time any material accumulations and caking on the housing walls above the mash level avoided.

The device according to the invention is thus characterized by the high quality of the mash produced and a particularly reliable, trouble-free operation.

An embodiment of the invention is illustrated in the drawing. It shows

F i g. 1 shows a schematic section through a

device according to the invention for the production of mash;

F i g. 2 is a schematic plan view of the funnel designed bottom of the housing chamber;

F i g. 3 shows a partial section through the water supply device in the area of an end face.

The device shown for the production of Mash contains a soft container 1, one provided with a gate valve 2 and a rotary valve 3 Inlet connection 4, two squeeze rollers 5 and 6 and one for homogenizing water and squeezed Chamber 7 serving malt with an agitator 8. The mash is drawn off by a pump 9.

In the housing 10 receiving the nip rollers 5, 6 and the chamber 7 are in the region of the two side walls 10a, 106 running parallel to the axes 5a, 6a of the squeeze rollers 5, 6, two water pockets 11, 12 are provided, which extend over the entire axial length of the housing 10 and a water film Let 16 or 17 emerge downwards. These two water films 16, 17 are used as Side walls 10a, 106 of the housing acting on guide surfaces are introduced into the mash (surface 18).

Furthermore, water supply devices (e.g.

40 cf.F r g. 1) provided. They generate in the area these two end walls 10c, 10c / each have a water film

41 or 42 (cf. the schematic representation in FIG. 2), by means of which any material accumulations that may arise in the area of these end walls 10c, XOd are dissolved or washed into the mash bath.

As in particular F i g. 1 shows the water supply devices provided in the area of the two end walls (z. B. 40) arranged approximately in the middle below the nip of the nip rollers 5 and 6; the water supply devices (e.g. 40) thus extend to both of them from a vertical plane running through the nip Pages. This covers the water supply devices generated by these water supply devices in the area of both end walls Water film especially the zones where, in the absence of these water supply devices, with a disturbing Material approach would have to be calculated.

F i g. 2 shows that of four inclined surfaces 43a, 436, 43c, 43 bottom of chamber 7, which is delimited in the shape of a funnel. The water films 16, 17, 41, 42 generated by the various water supply devices thus all four sides of the chamber 7 containing the mash evenly and finely distributed Water supplied or flushed.

F i g. 3 shows an exemplary embodiment for the structural design of the water supply device 40. An the outside of the end wall 10c has a water chamber 45 provided with a water inlet 44, which is in communication with the interior of the housing via a slot-shaped opening 46. That through this opening 46 supplied water is directed downward by a diaphragm 47 and then meets the w inclined surface 43c of the funnel-shaped chamber bottom. Along this as a guide surface acting inclined surface 43c, the water film is introduced into the machine (surface 18), with any Accumulations of material, in particular on the inclined surface 43c above the mash level, rinsed off and be entered into the mash bath.
