160-240 Kg/Time Fluid Bed Industrial Dryer Machine , Powder Coating Equipment

Fluid bed industrial dryer machine and powder coating equipment

Application

Fluid bed can be applied in many fields of medicine, food, chemical industry, and agricultural and sideline products processing to granulate, coat and dry powder materials, such as tablets, instant drink, and condiment pellet. During production, materials should be loaded and discharged in a closed environment to prevent powders from diffusing to working environment. PLC controls the equipment to granulate, coat and dry on the fluid bed.

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).

• 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.
• 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.
• 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.
