At present, there are more than 200 manufacturers of wet mixing granulators in China, three or five people, and ten individuals are a factory, and regardless of technical strength, they are also put into production, and after-sales and after-sales supply and after-sales supply exist. There are great hidden dangers, and there are also pharmaceutical companies suffering. Some comments on the purchase of wet mixing granulators are for your reference only.
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. Our products are designed as sandwich pots. The design period is 10 years without deformation.
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 for traditional Chinese medicine extract and high-viscosity Chinese medicine extract, the gap of 2mm is easy to produce the bottom. It is very difficult to remove after the bottom, so that the pot cannot be repaired after deformation. Germany “Grata†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. The design parameters are not deformed for 10 years.
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. Our company's equipment uses foreign imported or domestic high-quality synchronous belt synchronous wheel (models such as parts list) transmission, can provide full power, design parameters for 8 years without replacement.
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. Our company's mixing paddles are controlled by French Schneider's frequency converter, which can guarantee the production of different kinds of Chinese medicine and western medicine. Design capacity is not replaced for 8 years.
5, sealing, cleaning system, such as black spots, spots in the granulation process, the whole pot material should be scrapped. The mixing paddle shaft of our company's equipment is sealed with air and water. 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. Please review the experts to pay attention to this. Our company's design capacity is not replaced for 8 years.
6. The “R†corner detail of the bottom of the pot body is also very important to match the R angle inside the bottom of the pot body. 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 bottom R angle of our company is made by the stretching process. It is different from the welding process of other manufacturers. The R angle joint of welding is 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. Please review the experts!
7. Human-machine interface, PLC system Our company adopts German Siemens PLC system and touch screen adopts Taiwan brand products. The main components are Chint and Delixi products. Good electrical components ensure a good operating system with powerful memory, editing and storage of pharmaceutical process menu functions. Easy to debug equipment and change varieties. The design and coordination ability of the operating parameters is not bad for 8 years.
