The surface of the three-dimensional mixer should be clean, smooth and free of dead spots, easy to clean or sterilize, and must not be scratched, hammered, or uneven. The mixing drum should be easy to clean. After the final cleaning, the inner wall of the mixing drum must not have any visible mark residue. The cleanliness of the mixing drum should be no more than ug/g. The three-dimensional mixer barrel must not be subject to powder leakage during operation. The material in contact with the drug in the three-dimensional mixer shall be resistant to corrosion and chemical changes or adsorption of drugs with the drug. The maximum allowable surface roughness of the three-dimensional mixer mixing drum and the drug contact surface is 0.4 μm, and the upper limit of the external surface roughness Ra is 0.8 μm. The mixing cylinder of the three-dimensional mixer has a unique design. The inner wall of the three-dimensional mixer is precisely polished, with no dead corners and no contaminated material. The material is discharged smoothly under the action of its own weight without any remaining material, and it has no pollution, is easy to discharge, and does not accumulate material. Ease of cleaning and other advantages; due to the multi-directional movement of the mixing cartridge, so that the material within the barrel mixing point, mixing effect is significant, the mixing uniformity is higher than the average uniformity of the mixer, the uniformity of the drug content error is lower than General mixer, while the maximum volume of the three-dimensional mixer is 40% higher than the maximum volume of the general mixer is 40% of the full volume of the cartridge body, up to 85%; the material is mixed in a closed state, does not produce work environment Pollution; 5, low height, small swing space, construction (technical mezzanine) generally do not need to stay odor million years, penalty area is small. The three-dimensional mixer has low vibration, low noise, freely adjustable work stations, convenient installation and maintenance, and long service life;
The rules that must be observed when installing 3D mixers:
When loading and unloading, the electric power of the three-dimensional mixer must be shut down to prevent the malfunction of the electric appliance and cause unnecessary accidents; before starting the machine, avoid standing in front of the cylinder to avoid accidents. The mixing of the three-dimensional mixing machine is a three-dimensional space mixing, and a security fence is added within the valid range of the barrel to avoid a life safety accident.
The three-dimensional mixer is not only suitable for mixing common materials in various industries, but also suitable for mixing oily, sugary, high viscosity, flammable, explosive, warming up, heating and softening materials. Such as drugs, powder coatings (premixed and finished product mix), leveling agents, food additives, etc., and can be used with the production line. Mixing methods are many: the general mixer has only one kind of power mechanism, only one or two kinds of mixing methods, three-dimensional mixer uses three sets of power mechanism, there are radial overturn, axial reverse, axial mixing, lateral stirring, etc. The characteristics of simultaneous mixing methods. Can add inverter, speed motor. Reasonable structure, inflatable seal drive shaft, can be switched to water when cleaning. Fluidized granulation, granulation approximate ball line, good fluidity. Reduces 25% of the adhesive compared to traditional processes and shortens drying time. Each dry mixing for 2 minutes, granulation 1-4 minutes, the effectiveness of 4-5 times higher than the traditional process.
A three-dimensional mixer can mix a variety of materials into a uniform mixture, such as mixing cement, sand, gravel, and water into a concrete wet material; it can also increase the surface area of ​​the material to contact to promote chemical reactions; it can also accelerate physical changes, such as Granular solutes are added to the solvent, which accelerates dissolution and mixing by the action of the mixing machine. The three-dimensional mixer is a novel material mixer widely used in pharmaceutical, chemical, food, light industry and scientific research institutions. The machine can mix flow properties very uniformly. Good powdered or granular material, so that the mixed material achieves the best results.
