In the pharmaceutical industry production, most powder drugs cannot be separated from mixing equipment. There are many types of mixing equipment used in the pharmaceutical industry in China, mainly including one-dimensional, two-dimensional, three-dimensional motion mixers, as well as V-shaped, double cone, planetary cone and other mixers, each with its own characteristics. However, the mixing equipment used in the pharmaceutical industry has its requirements, which include achieving mixing uniformity, a certain production scale, and corresponding process requirements, as well as effectively controlling dust, cleaning, and disinfection (sterilization). There seem to be some difficulties in meeting these requirements in the numerous mixing equipment mentioned above. The emergence of the hopper mixer will make up for the shortcomings of many mixing equipment. It combines the characteristics of most mixing equipment and is currently being promoted by the mixing process of the pharmaceutical industry at home and abroad. Therefore, based on extensive absorption and in-depth research of various domestic and foreign models, after three years of absorption, digestion, comparison and research, combined with national conditions, the HLD series hopper mixer has been carefully developed.
Hopper mixerHaving many characteristics of a three-dimensional motion mixer, the principle of a hopper mixer is as follows: firstly, like other rotary mixers, it uses the rotation of the hopper to cause the material to flip up and down, enlarge and shrink, and mix left and right to achieve a uniform mixing effect, that is, two mixing movements of convection and diffusion; The second is to use the flipping axis of the hopper (the centerline of the hopper column passing through the midpoint of the opposite side) to form a 30 ° angle with the rotation axis (the left and right arm axes). When rotating, the material can move tangentially along the hopper wall, achieving the effect of shear mixing and producing a stronger mixing effect. The combination of these two aspects creates a complex and diverse motion trajectory for each particle, allowing it to change its position at any time and achieve a high level of mixing effect.
