Rotary granulator is an important equipment widely used in industries such as pharmaceuticals, food, and chemicals, mainly used to convert powder materials into granular products through wet granulation.The control and recording of parameters such as turntable speed, spray rate, and inlet air temperature have a significant impact on the quality and performance of the granules during the granulation process. This article will explore the precise controllability of these parameters and their recording methods.
1. Controllability of turntable speed
The rotational speed of the turntable in a rotary granulator is one of the key factors affecting particle formation. The change in rotational speed directly affects the particle size, morphology, and density of the particles. Modern granulators are usually equipped with advanced variable frequency drive systems that can accurately adjust the speed. By configuring a digital control system and feedback mechanism, operators can monitor the speed of the turntable in real time and make necessary adjustments. In addition, digital recorders can record speed data in real-time for subsequent quality analysis and process optimization.
2. Controllability of spray rate
Spray rate is another key variable that affects particle humidity and adhesion. The spray system generally includes a high-pressure pump and a nozzle. By adjusting the flow rate of the pump and the opening size of the nozzle, precise control of the spray rate can be achieved. Modern spray systems often combine flow meters and automatic control technology to achieve real-time monitoring and recording of spray rate. This intelligent control method effectively improves the stability of the spraying process and ensures the consistency of particles.
3. Controllability of inlet air temperature
During the granulation process, the inlet air temperature is crucial for the drying and shaping of the particles. Temperature control systems typically use hot air circulation technology to precisely control the inlet air temperature by adjusting the operating status of the heater and fan. The temperature sensor can monitor the wind temperature in real time and transmit the data to the control system for adjustment. In terms of archiving, data loggers can record temperature changes, providing a basis for subsequent process improvements.
4. Technical means of parameter recording
Accurate recording of various parameters is crucial to ensure the traceability and compliance of the granulation process. Many modern rotary granulators are equipped with automated data acquisition systems that can record key information such as speed, spray rate, and inlet air temperature in real-time during the production process. These data can not only be used for process control, but also serve as a basis for quality assurance, facilitating future audits and inspections.
5. Conclusion
Through advanced control and monitoring technology, key parameters such as turntable speed, spray rate, and inlet air temperature of the rotary granulator can be accurately controlled and recorded. This not only improves the stability and consistency of the granulation process, but also provides strong support for subsequent process optimization and quality assurance.
