Abstract

The invention relates to the technical field of freeze-dried powder production, in particular to a material mixing device used before freeze-dried powder preparation. The material mixing device comprises a preparation kettle, a material mixing cavity is arranged at the top of the preparation kettle, a material blending main frame is arranged at the top of the material mixing cavity, a plurality ofmaterial blending brackets are arranged on the material blending main frame, and transmission frames are arranged at the tops of the material blending brackets. A power input shaft and a preparationpower shaft are respectively arranged on the transmission frame, a driving disc and a driven disc are respectively arranged on the power input shaft and the preparation power shaft, an outer edge block piece is arranged on the edge of the disc surface of the driven disc, a plurality of outer support bulges are arranged on the outer edge block piece at equal angles, and the number of the outer support bulges is related to the proportioning amount. A feeding shaft is also arranged in the inner cavity of the material blending bracket. The outer supporting protrusions are designed to be arranged at equal angles, the number of the outer supporting protrusions is related to the matching amount, and continuous production of raw materials is guaranteed; and a numerical control weighing mode is notneeded, so that the overall feeding operation effect is greatly optimized.

Description

technical field [0001] The invention relates to the technical field of freeze-dried powder production, in particular to a material mixing device before preparation of freeze-dried powder. Background technique [0002] Freeze-dried powder is a sterile powder injection made by freezing the medicinal liquid into a solid state in a sterile environment and sublimating and drying the water in a vacuum. The freeze-drying method is an effective preservation method for drying heat-sensitive products and substances that need to maintain biological activity. method. When formulating the freeze-dried powder, it is necessary to melt the different components in the liquid medicine into one body, so that the quality of the powder will be uniform in the subsequent freezing and sublimation, but the existing mixing and stirring is not sufficient, and the full mixing effect cannot be guaranteed. [0003] The Chinese patent (authorized announcement number: CN211586297U) discloses a freeze-drie...
