Descrição do produto
Vertical boiling dryer
Fluid-bed processing is mainly used for the mixing of powder material, drying and granulating (coating) in pharmaceutical, food, chemical, agricultural and sideline product processing industries, such as tablet, instant powder and condiment granules. The process of feeding and discharging material for this equipment should be finished in the airtight space to avoid the powder spreading to the working environment. It‘s controlled by PLC. For wet type granulating machine, it adopts negative pressure or air blast to make the finished granules enter the fluid bed for drying in airtight way.
Brief introduction for top spray system
It consists of a cone-shaped material trough and diffusion (spraying) chamber. The processing airflow passes through the airflow distribution board and screen net from the trough bottom to enter this equipment. When the flow rate of inlet air overcomes its gravitational force, the material in trough can form eddy flow to move (fluid bed).
1.The inlet airflow from the bottom up will push the material in the trough to move upward. As with a certain angle of the trough, the aggregative fluidization of the material in it is very intense.
2.The material pushed by the airflow, enters into the diffusion chamber. As the space of diffusion chamber is larger than that of trough, the air flow velocity in chamber will be lower than in trough and the speed of material granules in chamber will decrease. When the gravity force of granule itself overcomes the pushing force of inlet airflow from the bottom up, it will fall down and return to the edge area of trough. In the whole process, the granules will move back and forth between diffusion chamber and trough to form irregular fluidization.
3.The aim of granulating machine is using fine powder to produce dust-free and flexible granules. Coating refers to coat for those finished fine and uniform granules.
When granulating and coating with top spray device of fluid bed, the powder or granules rise from the trough bottom in fluidized state; the adhesive or coating liquid is sprayed to the fluid bed by the nozzle of spray gun installed in the diffusion (spraying) chamber to granulate or coat the material. Via the thermal current entering from bottom and heated airflow distribution board to do heat exchange, the material will be dried.
In the phase of material being blown by air, the surface of each granule will be fully showed in the airflow so that it can achieve the best atomizing spray medium and drying result.
The top spray technique is suitable for drying process. Dismount the spray gun in diffusion (spraying) chamber, the top spray device turns to be a fluid bed drier.
