The working capacity of the flash dryer is mainly reflected in the following aspects:
Efficient drying: The flash dryer adopts pure convection heating, which makes the wet material dry quickly under the action of hot air flow through direct or indirect heating. This heating method can make the material contact temperature high, the gas can operate quickly, and achieve efficient drying with a short residence time.
Uniform product quality and low thermal damage: Due to the short residence time of the flash dryer, the product can be kept at a low temperature during the drying process, thus avoiding the problem of uneven product quality and thermal damage.
Flexible configuration: The flash dryer can be configured as an open-circuit, partially closed circuit or fully closed circuit removal system. This flexible configuration allows for the needs of different processes and enables efficient and efficient use of exhaust gases.
Handling of fine-grained or powdery materials: The flash dryer is suitable for processing fine-grained or powdery materials, with the characteristics of short residence time and continuous feeding, which can achieve an efficient and continuous drying process.
A variety of feeding devices are available: According to different product characteristics and optimized feed rates, the flash dryer is equipped with a variety of feeding devices, including sling feeders, cold crushing, direct screw feeders, etc., to meet the needs of different processes.
Optimisation of products** and reduction of particulate emissions: Flash dryers are able to separate the final dry matter from the dry air by means of a bag filter or cyclone technology. Two-stage collection technologies, such as cyclone humidifiers, can also be used when product** or particulate emissions are reduced when it is necessary to optimize the product** or reduce particulate emissions into the atmosphere.
To sum up, the flash dryer has the characteristics of efficient drying, uniform product quality, flexible configuration, and processing fine particles or powdery materials, and is an ideal equipment for drying filter cakes, fiber materials, sludge and slurry.
