Embodiment 2

[0051] For the dry granulator of this embodiment, on the basis of the first embodiment, the feeding mechanism described in the embodiment is further limited. Such as Figure 5 , Image 6 with Figure 7 As shown, the feeding mechanism also includes a housing structure 12. The housing structure 12 includes a flat material part and a mounting part. A feeding channel is formed between the flat material part and the material receiving part 2. A storage bin for storing materials. Preferably, the edge line of the flat material part is parallel to the material receiving plate 14, so that the material passing through the feeding channel is evenly laid on the material receiving part 2. It should be noted that the structure of the flat material part can be set according to actual needs.

[0052] Specifically, the accommodating structure 12 in this embodiment is a U-shaped structure in a top view, and the feeding structure 13 is connected to the accommodating structure 12 to block the ...

Abstract

The invention relates to the technical field of particle preparation, in particular to a dry type granulator which comprises a rolling mechanism, a granulating mechanism and a box body. The rolling mechanism comprises a first driving part and a rolling assembly connected with the first driving piece, and the first driving piece is suitable for driving the rolling assembly to act. The granulating mechanism comprises a second driving piece and a granulating assembly connected with the second driving piece, and the second driving piece is suitable for driving the granulating assembly to act. The rolling assembly and the granulating assembly are arranged in the box body, and the first driving piece and the second driving piece are arranged outside the box body. The dry type granulator further comprises a feeding mechanism which is arranged on one side of the box body and comprises a material bearing piece and a feeding structure, the material bearing piece is used for bearing materials, and a feeding channel is formed between the feeding structure and the material bearing piece. The dry type granulator is compact in structure and small in occupied space, two working procedures of rolling and granulating can be completed on one device during operation, the operation is convenient, and the granulating efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of particle preparation, in particular to a dry granulator. Background technique [0002] In the pharmaceutical industry, it is widely involved in the processing of various active pharmaceutical raw materials and one or more excipients. Most of these raw materials are fine powders with different particle sizes, uneven density, poor fluidity, and easy layering. These raw materials must be processed through a granulation process. The existing dry granulation system mainly includes a rolling device and a granulation device, wherein the material is pressed into a sheet or strip by the rolling device, and then the sheet or strip is cut into granules by the granulation mechanism shape. Contents of the invention [0003] Therefore, the present invention provides a dry granulator. [0004] Technical scheme of the present invention is: [0005] A dry granulator, including a rolling mechanism, a granulation mec...
