Problems solved by technology

If the operation of such a granulator were to be switched to operating new molten material, this would result in an undesired, relatively large amount of waste that would not enter the production process; this drives up costs, especially in the case of relatively expensive molten materials such as pharmaceuticals active ingredient case

Embodiment Construction

[0035] refer to Figures 1 to 3 , the nozzle plate 10 according to the first embodiment of the present invention will be described first.

[0036] Such as Figures 1 to 3 As shown in , eight nozzles 20 are formed in the nozzle plate 10 . This number is not limiting and any other desired number of nozzles 20 may be provided. Each nozzle 20 has a nozzle channel 21 and a nozzle hole 22 through which molten material can be expelled at the side of the nozzle plate 10 (this is called the front side 12) to be cut off by the blades of the cutter head.

[0037] The nozzles 20 are arranged in the nozzle plate 10 such that the nozzles lie on a circle around the central axis M so that all nozzles 20 are at the same distance from the central axis M. The nozzles 20 may be distributed unevenly on the circle. Preferably, however, the nozzles 20 are evenly distributed on the circle such that any two adjacent nozzles 20 are equidistant. The nozzles 20 may also be located on a plurality of ...

Abstract

A nozzle plate for a granulating device. The nozzle plate has a plurality of nozzles for the passage of melt, wherein the nozzles are arranged such that they lie on a circle about a center axis. Each nozzle has a nozzle channel and at least one nozzle opening. A recess for receiving a melt flow is formed on the surface of the nozzle plate opposite the surface comprising the nozzle opening. The recess can also be centered on the center axis. A plurality of flow channels in fluid communication with the recess and at least one flow channel are formed in the nozzle plate extending radially away from the center. A granulating device having such a nozzle plate.

Description

technical field [0001] The present invention relates to the field of granulation of molten materials consisting of active pharmaceutical ingredients or combinations of active pharmaceutical ingredients or thermoplastic materials, in particular nozzle plates which can be used for this purpose. Background technique [0002] In general, granulation plants with extruders or melt pumps are often used to granulate molten materials, for example consisting of active pharmaceutical ingredients or combinations of active pharmaceutical ingredients or of thermoplastic materials such as polyethylene or polypropylene , wherein the molten material is forced through the die plate into a cooling liquid (eg water) and there cut by a cutting device with at least one blade passing over the hole of the die plate to produce pellets. [0003] In prior art granulation plants a nozzle plate is usually used for this purpose, having a plurality of nozzles arranged in a circular shape designed to pass ...
