Description
The raw materials to be treated should distribute on the conveyer belt through suitable mechanism such as star distributor, swing belt, crusher or granulator, the conveyer passes through the channel including of one or several heating unit. Each heating unit is equipped with air heater and circle system. Each channel has one or several damp discharge systems. When the conveyer passes through it, hot air will pass through the raw material from up to low or from low to up. In this way raw materials can be dried evenly.
Main Features:
1) Wide applications: It is successfully used on all types of powders, agglomerates, granulates, especially those which fluidize poorly due to a broad particle size distribution. The fluid bed can be operated as a single drying or cooling unit - often associated with a spray drying system.
2) Energy-saving: Due to strong mechanical vibration, wet material can be perfectly fluidized and move forward with slow air flow velocity. Energy consumption is much lower than normal fluid bed dryer.
3) Adjustable residence time: Different residence time of wet material in drying chamber can be achieved by regulating the angle of vibration motors to meet different drying requirements in moisture.
4) Easy operation and maintenance: The whole drying system is highly automatic. The simple but practical design can not only reduce production cost but also the maintenance and repair cost.
