The Micron Flash Dryer has been the first drying system of this type patented in the world.Key features Drying, Milling and Classifying on one single unitMoisture and fineness controlFeed viscosity from 0,2 to 10 m.Pa.s.Drying conditions up to 650°C gas temperatureCompact designNo feed moisture limitationOpen, closed- end recycle system conceptLow residence timeFlash drying down to submicron materialsDrying, Milling and Classifying in one machine The dried particles then enter the classifying zone in the top of the dryer. Fine particles below a specific set point leave the dryer at the outlet and are collected in a suitable filter. Coarse particles rejected by the classifier are internally recycled and returned to the grinding section for further processing.Products SuspensionsSlurriesPastes and doughWet powders with agglomeratesFilter cakesPress cakes after press filtrationThixotropic materialWet grinded nano particle productsDegree of dispersion Based on the amount of dispersion required during the drying process, the execution of the grinding section can be adapted. Several rotors and classifiers give various degrees of dispersion/grinding: Gentle dispersionHigh dispersion for solidsMillingHigh dispersion for suspension and sticky/viscous liquidsSchematic sketch of the heating principle of the Micron Dryer The Micron Dryer is a universal dryer combining direct drying. Heat is basically transferred into the product by a flow of gas to evaporate the solvents and volatiles.Based on the application, different heating media can be used:Hot-Air (either directly heated by gas burning or through an heat exchanger)Nitrogen closed loop for explosive materialsSuperheated steam for higher capacities and sterilization of productsMain features of the Hosokawa Flash dryerOne single machine for 3 unit operations: Drying grinding/dispersing and classifying in one, to save space and operational costs.Particle size control: The dynamic classifier ensures a uniform product both in moisture content and in particle size distribution of the product.Minimal dust emissions: The system operates under negative pressure which minimising dust getting into the environment.Energy efficient operational plant: Data have proven that this concept requires less energy in comparison to any other system with consumption of lower than 1 kW for evaporation of 1 kg water/h.Multi purpose: cakes or slurry in the same machine.
