Dry method pelletizing machine

Abstract

The invention discloses a dry method pelletizing machine. The dry method pelletizing machine is characterized by comprising a loading mechanism, a vertical feeding mechanism, an inclined feeding mechanism, a tabletting mechanism, a granulating mechanism, a straightening mechanism and a screening mechanism, wherein the loading mechanism comprises a charging basket which is communicated with a vacuum system, the vertical feeding mechanism comprises a vertical feeding motor and a vertical feeding screw rod, the inclined feeding mechanism comprises a feeding cylinder, a feeding screw rod and a feeding motor, the tabletting mechanism comprises an upper pinch roller and a lower pinch roller which rotate reversely, the granulating mechanism comprises a granulating wheel, the straightening mechanism comprises a straightening wheel, a straightening device and a screen straightening device, the screening mechanism comprises a screening barrel, a sieve tray and a powder receiving tray, and a feeding hole, a fine powder discharging hole and a finished product discharging hole are formed in the wall of the screening barrel. The dry method pelletizing machine is compact in structure, reliable in sealing and high in working efficiency, high quality finished product particles can be produced, fine powder ratio of finished product is controlled to be less than 4%, the dry method pelletizing machine can be applicable to various powders with different flowabilities, and automatic production can be completely realized.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical machinery, in particular to an improvement of a dry granulator. Background technique [0002] The dry granulator is used in the production of granule products, and its purpose is to compress various powders with different fluidities into qualified granule products with specified sizes. The dry granulation machine mainly includes a feeding mechanism, a feeding mechanism, a tableting mechanism, a granulation mechanism, a granulation mechanism and a sieving mechanism. The dry granulation machine has existed for many years, but due to various reasons including technical However, the dry granulation machines in the prior art generally have uncompact structure, unreliable sealing, and low work efficiency, and the quality of finished product granules (including technical parameters such as tablet weight difference, hardness, and disintegration degree) is relatively low. Poor, the fine powder cont...
