QPG Air Stream Spray Dryer(spray drying machine) Principles Air stream spray dryer 's work principle The clean air is heated and entered into drying tower, the raw material inside the tower is atomized into fine mist through muzzles of two or three flows. The raw materials carry out heat exchange with the hot air rapidly to evaporate the moisture (solvent) in the raw materials. The moisture or solvent is discharged accompany with hot air, then the power product is produced. Features QPG Air Stream Spray Dryer is good for raw materials that are large in viscosity, paste material, which the other equipment can not replace it. More varieties and wide application in drying with lower temperature. The nozzle is simple in structure, convenient in maintenance and low cost in operation.parameters spec 5 25 50 100 150 200 amount of evaporationKg/h t=150-90 1.5 7.5 15 30 45 60 t=200-100 2.5 12.5 25 50 75 100 t=250-100 3.75 18.75 37.5 75 112.5 150 t=300-100 5 25 50 100 150 200 t=350-110 6 30 60 120 200 240 pressure of air M 3 /min 0.9 0.9 1.1 1.5 2.7 3.4 pressure of air Mpa 0.4 0.6 0.7 Heat resource electricity,electricity+steam,coal(oil)combustion furnace consumption of heat 10 4 Kcal/h 1 5 10 20 30 40 power Kw 0.75 4 7.5 11 15 18.5
