Product Description
The working principle of the Fluid Bed Dryer Granulator is based on fluidisation technology. Inside the equipment, the material particles are placed on a porous distribution plate, and through the airflow blown in from the bottom, the material particles are in suspension, forming a fluidised bed similar to liquid boiling. During the fluidisation process, the binder is sprayed into the bed in the form of atomisation, which fully contacts and bonds with the material particles and gradually aggregates them into granules. At the same time, the hot air passes through the material layer, exchanges heat with the material, takes away the moisture and realises drying.
Equipment structure
The fluid bed dryer granulator is typically composed of the following components:
1. Hopper and charging system: employed for the storage and quantitative addition of materials.
2. Fluidised bed main body: comprising porous distribution plate, fluidisation chamber, drying chamber, etc. This is the primary location for material fluidisation, bonding and drying.
3. binder supply system: spraying the binder into the fluid bed in the form of atomisation.
4. Hot air supply system: the provision of hot air required for the drying process.
5. Dust removal system: collects dust produced in the drying process to prevent environmental pollution.
6.Finally, the control system is tasked with monitoring and regulating the operational parameters of the equipment, thereby ensuring the stability of the production process and the quality of the product.
advantages
-Multi-functionality: By integrating the functions of mixing, granulating, drying and coating, it can complete several process operations in one step.
- High efficiency: the hot air is in direct contact with the material, the heat and mass transfer rate is fast, and the drying and granulation efficiency is high.
- High product quality: the resulting particles are uniform, dense, good sphericity, good dispersion, suitable for a variety of application scenarios.
- Wide applicability: it can handle a variety of material forms such as solution, suspension and liquid paste.
- Good environmental performance: the system is completely closed, micro negative pressure operation, no dust flying, good operating environment.
- High degree of automation: equipped with PLC or DCS control system, easy to operate, remote monitoring and automated production.
application
Pharmaceutical industry: It is used for granulation and coating of medicines, such as granules for compressed tablets, granules for punches, granules for capsules and so on.
Food industry: It can be used for granulation of food such as sugar, coffee and cocoa powder.
Chemical industry: it can be used for granulation of pigment, dye, pesticide and other materials.
Other fields: It can also be used in bioengineering, electronic materials and other industries to dry and granulate various powdery and granular materials.
With its advantages of high efficiency, multi-functionality and environmental protection, the Fluid Bed Dryer Granulator has become an indispensable piece of equipment in modern industrial production, providing efficient granule processing solutions for various industries.
