LPG Series High-speed Centrifugal Spray Drier

Working principle

Air enters into hot air distributor“3” at the top of drying chamber through filter“1” and heater “2”，after which ,hot air is feed into the chamber homogenously in spiral state .liquid material is pumped to the centrifugal sprayer “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 lower by spiral separator“8” and exhausted to the outside by blower “9” ,see drawing below .

Characteristics and application

●High speed drying . Liquid material is centrifugally sprayed at a lager surface ,95-98% water content can be evaporated instantaneously 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 paralell direction with hot air, whose high temperature causes no over-heat to materials during water evaporation ,temperature distributtions inside the tower is showed in the following .

●Wide application .it's widely adopted for production of a various materials with different physic nature ,for instance ,polymer and resin ; dyeing -material and colour material ; ceramic and glass ; rust 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 .Homegeneous fine granulate of the product can be rest assured by the instananeous drying process .

●Simple process and convenient operation .solution with 40-60% humidity (90% is possible ) can be dried into powder powder product in one phase ,to which ,pulverization an screen are unnecessary ,thus 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 .

YPL Pressure Spray Drying Pelletizer

Working Principle

Solution ,suspension liquid ,emulsion ,paste material are atomized into fine drip by pressure spray nozzle under the pressure from high pressure pump ,then they are heat exchanged with high temperature quickly and continuously dried to fine materials in very short time and simple process .
