Continuous Drying Hot Air Mesh Belt Dryer for Coal, Coke Briquettes

Description
Continuous belt dryer is specially designed for drying different shapes of root vegetables and leafy vegetables. This drying machine has three-layer and five-layer structure, each layer can be independently adjusted the drying temperature according to the characteristics of the materials.
The working principle of this multilayer conveyor dryer shows as follows: the material is limit controlled by the hopper and is evenly spread on the mesh belt. The materials are driven by the motor to the top layer, then perform uniform motion in the multilayer belt dryer and conduct downward movement layer by layer. Cold air enters from the two axial flow fans, after ballasting via baffle plate, it will flows from bottom to top. There is equipped with a heater under the mesh belt at each layer. The cold air is constantly gradient heated, and then through the material layer. It will conduct mass transfer and heat transfer with the material layer, so that the moisture contained in the material can be rapidly vaporized and evaporated. When the cold air gets to the top layer, it has become saturated moist air, and will be discharged outdoors under the action of exhaust fan.

Features: 
1.The air volume, heating temperature, raw material residence time and feeding speed can be adjusted for this dryer to get best drying.  
2.All the system can be adjusted freely.  Mesh belt cleaning system and metrail cooling system can be used.   
3.The hot air circulates inside the dryer to save energy.
4.There is professional hot air distribution equipment inside the dryer. It make the hot air circulate equably.  
5.The belt dryer heating source can be steam, thermal oil,electricity or coal(oil) fired hot air oven.
