Three-dimensional mixer use precautions

The three-dimensional mixer has a unique design of the mixing barrel, and the inner wall of the barrel is finely polished, has no dead angle, no contaminant material, convenient discharging, easy to clean and easy to operate. Three-dimensional mixer use precautions:

1. The mixing of the three-dimensional mixer is a three-dimensional space mixing, and a safety protection column is added within the effective range of the material cylinder to avoid a life safety accident. Before starting the machine, avoid standing before the cylinder to avoid accidents;

2. When loading and unloading, the electric power of the equipment must be stopped to prevent the electrical appliance from malfunctioning and causing unnecessary accidents;

Technical requirements for 3D mixers

1. The surface of the three-dimensional mixer should be smooth, flat and free of dead angles, easy to clean or disinfect, and must not have scratches, hammer marks and unevenness.

2. The material in contact with the drug in the three-dimensional mixer should be resistant to corrosion, chemical changes or drug adsorption.

3. The maximum allowable value of the surface roughness of the three-dimensional mixer mixing barrel and the drug contact is 0.4 μm, and the upper limit of the outer surface roughness Ra is 0.8 μm. The mixing drum should be easy to clean. After the final cleaning by zui, there should be no visible residue on the inner wall of the mixing barrel. The cleanliness after cleaning is not more than ug/g. When the three-dimensional mixer is running idle, the noise sound pressure level is not more than 75dB (A). The three-dimensional mixer mixing drum must not leak when running.

4. The welding quality of the main force-receiving components (Y-type rocker arm, mixing barrel) of the three-dimensional mixer shall not be lower than the Class II requirements in the regulations. Mixing uniformity M 5. All fasteners of the three-dimensional mixer should be connected reliably and should not be loose. The three-dimensional mixer should be flexible and reliable in operation; any lubrication part is not allowed to pollute the working environment; when it is stopped, the discharge valve should be in the low position of the Zui.

6. The running direction of the 3D mixer drive shaft should be consistent with the running direction mark of the drive shaft. The three-dimensional mixer should be operated smoothly, and there is no creeping phenomenon in the case of the inorganic seat fastening. Under the determined process parameters, after the materials are thoroughly mixed, the mixing uniformity M should reach 99%.
