Embodiment Construction

[0038] exist figure 1 A nozzle 1 known from the prior art is shown in . The nozzle 1 comprises a nozzle body 4 with an inner tube 2 and an outer tube 3 . In this case, the inner tube 2 and the outer tube 3 are arranged coaxially to the axis X-X.

[0039] The inner tube 2 has a fluid channel 5 which is designed to supply the substance to be sprayed, preferably a liquid, very particularly preferably a dispersion, a suspension or an emulsion. This fluid channel opens into an escape opening 7 of the inner tube 2 in the region of the nozzle opening 6 . In a region facing away from the escape opening 7 of the inner tube 2 , the inner tube 2 has an attachment point 10 for a supply line (not shown) for the substance to be sprayed.

[0040] The outer tube 3 is arranged at a distance from the inner tube 2 , thereby creating an annular gap 8 for supplying gas, in particular atomizing air. The annular gap 8 opens into an escape opening 9 of the outer tube 3 in the region of the nozzle...

Abstract

The invention relates to a nozzle (101, 201, 301, 401, 501, 601, 701, 801, 901, 1001) for spraying materials, in particular, dispersions, emulsions or suspensions.

Description

technical field [0001] The invention relates to a nozzle for spraying substances, especially dispersions, emulsions or suspensions, said nozzle comprising a nozzle body with a nozzle opening, wherein the nozzle body has an inner tube and an outer tube, said An inner tube is connected to a supply for the substance to be sprayed, the inner tube has an inner wall and an escape opening, an outer tube is spaced apart from the inner tube and is connected to a supply for gas, the outer tube has an escape The outlet opening, and the outlet opening of the inner tube and the outlet opening of the outer tube are arranged in the region of the nozzle opening. Background technique [0002] Nozzles or spray nozzles are very frequently used in industrial processes, for example in granulation, in the coating of tablets and granules and in the direct production of granules. In this case, a coating and / or film is applied to the particles. Typically a liquid is sprayed, in which liquid the so...
