Description

Technical Field

[0001] The utility model relates to the technical field of medicine production, in particular to a batching device for medicine production. Background Art

[0002] Chemical drugs are raw materials and their preparations obtained by synthetic or semi-synthetic methods; new effective monomers extracted from natural substances or through fermentation and their preparations; optical isomers of known drugs obtained by splitting or synthesis and their preparations. Some chemical drugs require the use of a batching device to mix two or more materials during production, which is a unit operation to disperse them into a certain uniformity.

[0003] Through searching, it was found that the Chinese patent announcement number CN218047631 U proposed a "chemical drug batching device", which proposed an existing chemical drug batching device for production. Generally, the drug raw materials are directly added into the tank body, and then the drug raw materials are stirred and mixed by the stirring component in the tank body. However, the particle size of the solid particles in the pharmaceutical process will directly affect the quality of the drug, and the solid reactants are unevenly ground, which affects the uniformity of the drug dispensing. This patent sets a moving wheel to facilitate the movement of the main body, and sets a grinding mechanism to facilitate the first motor to drive the grinding disc to rotate and press, so as to grind the solid particles, and sets a stirring box to facilitate the second motor to drive the stirring blade to rotate, so as to stir the drug, and sets an aerator to facilitate aeration of the solid and liquid, and sets a sterilization box to facilitate the sterilization of the stirred drug by the sterilization lamp, thereby solving the above problems.

[0004] However, in actual grinding, the batching device may still mix drugs with larger particle sizes before they are completely ground, resulting in incomplete grinding and reduced drug quality. Utility Model Content
