Application and purchase of mixed granulation drying equipment and granulator:
At present, there are more than 200 manufacturers of mixed granulators in China, three or five people, and ten individuals are a factory, and regardless of technical strength, they are also put into production. After the conversion or closure, the after-sales and spare parts supply is very There are big hidden dangers, and there are also pharmaceutical companies suffering. Some comments on the selection of granulators for drying equipment:
1. Select the sandwich pot.
Because the single-layer pot is easy to shake and unstable during the production process, the sandwich pot can be cooled by heating for some special materials, which can meet the production requirements, and is not easy to be deformed at the bottom in the long-term pharmaceutical process.
2. Stir the gap between the paddle and the bottom of the pan.
The national standard stipulates that the gap is 2mm. In actual production, especially the Chinese medicine extract and the high-viscosity Chinese medicine extract, the gap of 2mm is easy to produce the bottom, and it is very difficult to remove after the bottom, so that the pot cannot be repaired after deformation. The company will make this gap within 0.5mm, and the equipment clearance of our company can achieve the accuracy within 1mm, which better solves the problem of uneven accumulation and mixing of similar products.
3. Transmission system Many wet granulator power systems use V-belt and pulley drive (low cost), resulting in insufficient agitation power in long-term production process, and easy to slip. The use of timing belt and synchronous belt drive can ensure long-term The manufacturing process is highly dynamic and ensures production requirements.
4. In the process of granulation, the variable frequency control system has different requirements on the rotation speed of the stirring blades in different time periods. Only the two-speed motor can not meet the production requirements. The inverter control can meet the production of various processes and can reach Good granulation effect 5, sealing, cleaning system, such as black spots, spots in the granulation process, the whole pot material should be scrapped. The paddle shaft is airtight and water clean. The cutting flying knife main shaft adopts double sealing of gas seal and metal hard seal (ie mechanical seal) to ensure 100% sealing effect, and the cleaning is cleaned with water. If an ordinary rubber sealing system is used, there will be serious leakage problems sooner or later, resulting in material scrapping, and the sealing and cleaning system is also the key point of this equipment.
6. It is also very important to match the 'R' angle detail of the bottom of the pot with the R angle inside the bottom of the pot. If the R angle is too small, the material cannot be rolled from bottom to top and the appropriate R angle is very important for the uniform mixing of the materials. The R angle is very demanding in the manufacturing process. The company is manufactured by the stretching process. It is different from the welding process of other manufacturers. The R-angle joints welded by the welding are combined with materials, water and other corrosive materials for a long time, which is easy to penetrate and leak. The design parameters are never leaked. Until the equipment is scrapped.
