Characteritics and application
High speed drying, Liquid material is centrifugally sprayed at a large surface, 95-98% water content the evaporated instaneously in the high temperature air flow, it therefore takes a few seconds only to finish the whole drying.
Applicable for heat sensitive materials, liquid drop flows in a parallel direction with hot air, whose high temperature causes no overheat to materials during water evaporation, temperature distributions inside the tower is showed in the following.
Wide applisation. It’s widely adopted for production of a various materials with different physic nature, for instance, polymer and resin, dyeing-material and color material, ceramic and glassrust remover and pesticide, hydrocarbon, milk products, blood and fish products, fertilizer, organic and no-organic compound etc.
Good dispersiveness, fluidity and dissolvity of the product. Homogeneous fine granulate of the product can be rest assured by the instantaneous drying process.
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 fewer 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.
Air enters into hot air distributor “3” at the top of drying chamber though filter “1” and
heater “2” after which ,hot air is fed into the chamber homogeneously in spiral state
liquid material is pumped to the centrifugal sprayed “7” after flowed through filter “5”,
where it is sprayed into fog drops and further contacted with hot air in large surface
before it is dried into granulate products in a very short time thanks to speedy
evaporation of the humidity, humid waste air is accumulated at the bottom of tower by
spiral separator “8” and exhausted to the outside by blower “9”, see drawings below.
Name and physical property of liquid material: solid content (of humidity), viscosity, surface tension, PH value.
Powder material unit weight, tolerated residue water content, size and highest temperature.
Final capacicty (or treat capacity).
Power supply: steam pressure, electrical capacity, fuel gas, oil, coal available.
Control requirement: automatic control to the temperature at both end is required or not.
Powder collection requirement: bag type accumulator is needed or not, environmental requirement to tail gas exhaust.
