The multifunctional fluidized bed granulation and coating machine is an improved drying device in the pharmaceutical industry. The fluidized bed includes various types such as reflux flow, piston flow, vibration, contact type, multi-layer fluidized bed, etc; The main devices of fluidized bed are separate opening and closed circulation. The fluidized bed uses an atomization operating system and coating method to complete the granulation, pellet making, coating, and drying processes in one go, reducing energy consumption.
Installation and usage skills of multifunctional fluidized bed granulation and coating machine:
1. When installing, choose a flat and vibration free ground to ensure stable operation of the equipment.
2. Check whether the connecting pipelines and transmission components are installed correctly, and connect the electrical wiring according to the drawing requirements.
3.Prepare coating solutions with different viscosities to accommodate particles of varying sizes and properties.
4. Adjust the inlet air damper to maintain the inlet pressure drop at 1500-2000Pa, ensuring sufficient fluidization effect.
5. Adjust the ratio of upper and lower airflow to 1:1-3. Control the evaporation rate well.
6.Adopting scientific process parameters to ensure coating quality and verifying that product indicators meet requirements.
7. During the coating process, the product temperature should be controlled to prevent overheating or low humidity.
8.Before debugging, the interior of the system should be cleaned to ensure that there are no impurities. Test run to verify that the transmission is normal.
9.The coating solution should be sterile and the system should be regularly cleaned and disinfected during operation.
10.Adjust the nozzle form, spray amount and nozzle height to obtain uniform coating effect.
