Fluidized drying granulator of pharmaceutical sealed linkage unit

Abstract

The invention relates to a fluidized drying granulator of a pharmaceutical sealed linkage unit, which comprises a filtering chamber, arc-shaped blocks are fixedly connected to the inner walls of the two sides of the filtering chamber, and a first filtering plate making contact with the two arc-shaped blocks is rotationally connected into the filtering chamber; the outer wall of the arc-shaped block located on the left side is fixedly connected with an impact block making contact with the lower side wall of the first filter plate, and the upper side wall of the first filter plate is fixedly connected with a fixing rod. The impact block is intermittently beaten by the filter plate I rotating in a reciprocating manner, so that the effect of vibrating the first filter plate is achieved, powder is prevented from blocking the first filter plate, the smoothness of the first filter plate is ensured, the powder filtering efficiency is ensured, and the pharmaceutical efficiency is improved; the hot air flow is driven by a stirring blade to fully impact and contact the rotating powder, and the powder is suspended and circularly flows in a fluidized state, so that uniform mixing is achieved, the granulation efficiency of the fluidized drying granulator is improved, and waste is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a boiling drying granulator of a pharmaceutical sealing linkage unit. Background technique [0002] The drug boiling drying granulator is a kind of production equipment in the pharmaceutical industry. The powdery material is put into the closed container of the hopper. Due to the action of the hot air flow, the powder is suspended in a fluidized state and circulated to achieve uniform mixing. At the same time, it is sprayed into the mist The coating material wets the fluidized substance in the container to make the powder coagulate into loose small particles. At the same time of granulation, due to the efficient drying of the hot air flow, the water evaporates continuously and the powder continues to solidify. The process is repeated to form an ideal , Uniform microporous spherical particles, complete three processes of mixing, granulation and drying in the container at o...

Problems solved by technology

[0003] When the existing drug boiling drying granulator filters the powder, the powder is easy to stick to the filter screen, which will block the mesh of the filter screen and affect the continuity of the powder. For filtration, it is necessary to manually clean the mesh dust of the filter to ensure its smooth filtration, which will cause the inconvenience of its filtration and affect the granulation of the drug
