Principe

 Seal circulation spary drying system works in a seal circumstance.The drying gas is usually inert gas,such N2 .It’s aspplicable for drying material with organic solvent ,toxic gas and the material easy to be  oxidized .adopt inert gas as cirulation gas,so to protect the material to be dried .The inert gas circulates after dehumidification process .N2 is heated and then enters into drying tower .Liquid material is conveyed to centrifugal nozzle by screw pump ,and then it’s atomized into the liquid mist by the atomizer ,the heat transferring process is finished in the drying tower .The dry product is discharged at the bottom of tower ,the evaporated organic solvent by the vacuum generated by the fan .Power or solid maerial will be separated in the cyclone and sprinkling tower .The saturated organic gas is drained out after it’s condedsed in the condedser .The gas not condensed recycles  in the system after it’s heated continuously .Ordinary normal centrifugal spray drying process is realized by air conveying and exhausting process.This is the obvious difference between explosion proof type sealed circulation centrifugal spray dryer .The dryig media in drying system is N2,the interior is under positive pressure .To keep positive pressure  stable ,the pressure transmitter controls the inlet amount of N2 automativally .
