Benefits of technology
[0006]By introducing the additives in the active area of the pressurized jet between nozzle and impact area these additives are entrained by the pressurized jet and are admixed at high energy into the dry materials without risking the disadvantages to be expected in connection with such materials with regard to soiling and plugging of the nozzle or nozzles. It has been surprisingly found that high speed liquid jets remain effective in regard to mixing even when they impact on supplied additives before they reach the impact area.
[0009]Such an embodiment can be used successfully not only in connection with producing doughs for baking that, because of processing of flour, water and special additives, are subject to especially critical processing conditions and must fulfill particularly high demands with regard to the work product. It has been found in this connection, that this admixture leads to high-yield dough and excellent quality.
Problems solved by technology
Also, the material flow of the materials after liquid and dry material have been combined is often prone to disturbances.
In particular, there are liquid or paste-like additives that can neither be added via nozzles nor by a supply device designed for dry material.

Embodiment Construction
[0011]The device referenced in the drawing with reference numeral 1 for admixing a liquid into flowable dry materials, in particular for the purpose of producing dough for baking, has a substantially cylindrical housing 2 with a vertical center axis 3; the lower section of the housing surrounds a mixing chamber 4. At the top, a filling chamber 5 for dry materials is provided (in this embodiment, flour for the preparation of dough for baking) and is open in the upward direction and also in the downward direction toward an exit opening 6 for enabling free flow of the dry materials. A lateral socket-shaped supply 7 is provided for feeding in dry material.
[0012]Compressed air inlets 8 can be provided as needed for loosening and making fluid the dry materials when there is the risk that the dry material clumps together or compacts easily. In the downward direction, the dry materials flow within the housing past a central distribution body 9 and then follow closely the housing contour in ...

A device for admixing a liquid into flowable dry materials has a housing with a mixing chamber having an inner wall with an impact area and an exit opening at a bottom end of the mixing chamber. Dry material is supplied from above into the mixing chamber and falls downwardly toward the impact area in front of the inner wall of the mixing chamber and exits through the exit opening. A nozzle generates a pressurized high-speed jet of a liquid impacting on the inner wall of the mixing chamber in the impact area and wetting the dry material with the liquid as the jet passes through the dry material and impacts against the inner wall. An opening inside the housing is provided for supplying liquid and pasty additives, wherein the opening is directed toward an area of the mixing chamber between the nozzle and the impact area.
Description
BACKGROUND OF THE INVENTION[0001]The invention relates to a device and a method for admixing liquids into flowable dry bulk material, in particular, flour for producing dough for baking, wherein in a mixing chamber that is positioned slantedly, in particular vertically, dry materials supplied from above and failing downwardly toward an impact area in front of an inner wall of the mixing chamber are wetted by a liquid in the form of a pressurized high-speed jet from at least one nozzle with impact against the inner wall and fall to an exit opening positioned below.[0002]New developments in particular in the area of preparing dough for baking have shown that the admixture of liquid into dry materials, for example, the admixture of water into flour when preparing dough for baking, can be accelerated, shortened and also reduced machine-technologically in that the individual components are no longer mixed with mechanical mixing tools and homogenized as a dough but that mixing, blending, ...
