spray drying temperature
Sprays are produced by a rotary wheel or nozzle atomiser11. Inlet temperature Aspirator flow ratespeed Feed flow rate Concentration of the material being sprayed A higher aspirator rate leads to a higher degree of separation in the cyclone. Centrifugal Spray Dryer 3l H 150l H For Food Industry Spray Dryer Food Industry Newer designs have increased the inlet temperature to 428 o F 220 o C or higher and reduced the outlet temperature to around 185 o F 85 o C. . Spray drying often is used as a method of encapsulation. Separation The final step in the spray drying process is to separate the dry particles from the gas. For instance drying of skim milk concentrate of 50 total solids using air inlet temperature of 200C to produce a powder with final moisture content 36 will in singlestage drying require an outlet temperature of 101C whereas only 73C when drying to 7 moisture in the first stage of a two-stage dryer.
