Structure and Process Principle of Boiling Granulation Drying Machine
Date: 2025-02-11Read: 9
Boiling granulation dryer is a commonly used equipment for manufacturing granular particles. Compared to other equipment, the boiling granulation dryer has the following advantages:
1. Being able to simultaneously complete the granulation and drying processes effectively improves production efficiency;
2. It can handle materials with a wide range of particle sizes, and is more suitable for materials with less strict particle size distribution requirements;
3. The equipment has a simple structure, is easy to maintain and clean, and is more convenient for production workshop operations.
The boiling granulation dryer mainly consists of the following parts:
1. Feeding system: used to transport raw materials to the interior of the equipment. Generally, spiral conveyors or belt conveyors are used for material feeding;
2. Drying room: used for heating and drying materials, common heating methods include electric heating, steam heating, or gas heating;
3. Proportional pump: used to transport liquid excipients into materials for mixing and granulation;
4. Class nozzle: sprays liquid auxiliary materials onto the surface of materials through high-speed airflow, forming particles;
5. Slag discharge system: discharge the granulation particles from the inside of the equipment;
6. Dust removal system: Precision filters or cyclone separators are used to filter and collect the generated dust.
Boiling granulation dryer is a device that utilizes powder materials to instantly sublime and expand in the airflow to form granular materials. Its process principle can be summarized into the following three steps:
1. The spray equipment sprays wavy fluid into the powder material to make it locally wet on the surface.
2. Heating air passes through the material from below to form tangential flow and upward airflow, causing the liquid fluid soaked on the surface of the material to sublime and expand instantly, and bond into different particles.
3. The processed material enters the upper separation device with the airflow, and after particle separation, it is discharged. The gas is discharged after dust removal treatment.
The flow state between liquid fluid, powder material, and hot air during the entire process will affect the granulation effect. Therefore, precise control of the process parameters of the equipment is also an important aspect of understanding the standing stone boiling granulation dryer.
