Abstract

The present invention discloses a research bench for particle flow falling characteristics in a finite space. The research bench comprises a hollow and vertically placed particle falling container (6); the top of the particle falling container (6) is communicated with a funnel (9); the upper part of the particle falling container (6) is further provided with a material conveying device, and the material conveying device is configured to convey the externally injected particles to the funnel (9); the material conveying device has a material outlet (10) arranged at the inner upper portion of thefunnel (9); and the bottom of the particle falling container (6) is in communication with a hollow material collector (7) with an opening on the top. According to the research bench for particle flowfalling characteristics in the finite space provided by the present invention, the particle flow falling process in the tank as a finite space can be visually observed, and the influence of differentphysical parameters of the particle flow on the particle falling motion characteristics (such as whether the particles are falling in groups) in the falling process can be observed.

Description

technical field [0001] The invention relates to the field of experiment technology, in particular to an experimental platform for researching the falling characteristics of particle flow in a limited space. Background technique [0002] At present, in the pharmaceutical field, solid preparations account for about 70% of pharmaceutical preparations, and commonly used solid preparations include powders, granules, and films. In the preparation process of solid preparations, the drug particles need to be pulverized and sieved first, and then sterilized before being processed into corresponding preparations. Therefore, the processing of preparations is inseparable from the coupling of drug powder particles and air. [0003] Today’s pharmaceutical companies generally use high-temperature and high-pressure steam sterilization to process the powder in the process of processing the powder (for example, the pressure is 103.4kPa, the steam temperature is 121.3°C, and the maintenance ti...
