The SDS Model 72 spray dryer is a larger version of our Model 60 spray dryer, with many of the same features and options.  It is used for evaporation rates to 345 lb/hr of water.  The drying chamber is 6 feet in diameter, with a typical straight side of 12 feet.

The Model 72 spray dryer can produce as high as 150 micron average particle size when using pressure nozzle atomization in the mixed-flow configuration, with little or no wall buildup.  When used with pressure nozzle atomization, the Model 72 is especially effective in producing powders with improved "flowability", tighter particle size distribution, and higher bulk density, all with a higher overall yield when compared to two-fluid nozzle and rotary atomization.

The actual evaporation rate and maximum average particle size achievable depends upon the feed being processed, the site elevation, the air temperatures used for drying, and the nozzle configuration used.

Because the Model 72 system is typically mounted on structural steel supports with stairs and access platforms, the overall height and footprint can vary greatly depending upon the layout preferred by the customer, the dryer's atomization configuration, and if chamber solids separation is used.  A typical layout would be between 20-28' in overall height and have a footprint of approximately 22' x 19'.
