The flash dryer is widely used in the dispersion and drying of granular, powdery, paste-like and filter cake-like false agglomerates in the chemical, pharmaceutical, building materials, food, feed, and other industries. The flash dryer has the advantages of the small occupied area, low energy consumption, high thermal efficiency, and continuous mass production.
The flash dryer body is provided with a rotary cutting device, and the dry material is subjected to shearing, rotating, collision, friction, etc., so that the material is pulverized and refined, and is highly dispersed, thereby achieving the effect of efficiently and rapidly evaporating water. The dryer is equipped with an air filter to achieve the cleanliness of the hot air and to provide production conditions for the hygiene requirements of the food industry. The machine sets the cyclone separation and collecting materials. In addition, the bag dust removal receipt is added to increase the material recovery rate. It can improve the economic efficiency of enterprises. The dryer can be customized according to user needs. Working Principle
The flash dryer consists of a dry main engine, feeder, heat source device (hot air furnace or steam), air filter, air blower, cyclone separator, bag filter, and induced draft fan. The hot air tangentially enters the bottom of the dryer and is driven by the agitator to form a powerful rotating wind field. The paste material enters the dryer by the screw feeder. Under the strong action of the high-speed rotating stirring paddle, the material is dispersed under the action of impact, friction and shearing force, the block material is rapidly pulverized, and it is fully contacted with hot air and heated, and dry. The dehydrated dry material rises with the hot gas flow, and the classification ring intercepts the large particles. The small particles are discharged from the center of the ring to the outside of the dryer and are recovered by the cyclone separator and the dust collector. The dry material is not dried or the bulk material is subjected to centrifugal force, fell to the bottom and was crushed and dried.
