One end is fixed on the stir shaft, the internal protecting wall of the other end and said drying oven leaves the strip scraper in gap, the position that said scraper is provided with below the high test bleaching powder crude product inlet, hot-wind inlet above;
Said scraper comprises upper blade and lower coating blade, and upper blade is arranged on the top of lower coating blade;
The hot blast temperature of sending into drying oven from hot-wind inlet is 130～170 ℃, and the weight water content of sending into the high test bleaching powder crude product of drying oven from high test bleaching powder crude product inlet is 40～50%, and based on the weight of said bleaching powder crude product, hot blast rate is 20000～30000 meters
3/ hour, the linear velocity of hot blast in drying oven is≤25 meter per seconds, stirring velocity is≤130 rev/mins; Bleaching the residence time of smart crude product in drying oven is≤5 seconds.
The product that is obtained, weight water content are 4～10%, can satisfy the needs that use in relevant field fully.
By above-mentioned disclosed technical scheme as seen, method of the present invention, equipment is simple, and processing ease, material can not glue wall in drying oven, the drying efficiency height, thus reduced energy consumption and environmental pollution, be convenient to industrializing implementation.
