Characteristics and Application:   1   High speed drying, Liquid material is centrifugally sprayed at a larger surface, 95-98% water content can be evaporated instantaneously in the high temperature air folw, it therefore takes a few seconds only to finish the whole drying.   2   Applicable for heat sensitive materials, Liquid drop flows in a paralell direction with hot air, whose high temperature cause no overheat to materials during water evapoartion, temperature distributions inside the tower is showed in the following.   3   Wide application.it widely adopted for production of a various materials with different physic nature, for instance, polymetand resin; dyein-gmaterial and colour material; ceramic and glass; mst remover and pesticide; hydrocarbon; milk products; blondand fish products; fertilizer; organic and no-organic compound etc.   4   Good dispersiveness, fluidity and dissolvity of the product. Homegeneous fine granulate of the product can be rest assured by the instananeous drying process.   5   Simple process and convenient operation, solution with 40-60% humidity(90% is possible) can be dried into powder product in one phase, to which, pulverization and screen are unnecessary, this purity of the product is improved at Iewer process, size/bulk density and water content of the product can be easily adjusted and controlled in a certain limit according to actual operation conditions.
