The WhirlJet SprayDry Nozzle, available from Spraying Systems Co , is a large orifice spray drying nozzle and produces a hollow cone spray pattern with uniform drop distribution to ensure consistent particle size and reduce product wastage.

The body of the WhirlJet SprayDry Nozzle is constructed from stainless steel and features a tungsten carbide whirl chamber to resist corrosion and wear. Orifice inserts are also constructed from carbide, however both of these parts can be fabricated from other materials for specific applications.

Ideal for producing large particle sizes in high volume spray drying applications, interchangeable orifice inserts and whirlchambers on these spray dry nozzles allow users to select a nozzle that fits their exact application needs. Ideal applications for the WhirlJet include spray drying of:

  • soaps and detergents
  • dyes and pigments
  • coffee and tea
  • plastics and resins
  • biochemical
  • fertilizers and pesticides
  • pharmaceutical
  • dairy.
There are two models of WhirlJet SprayDry spray drying nozzles, the Type AA104 for high pressure applications and the Type SSTC for reduced maintenance and downtime.

The AA104 uses a stainless steel lock screw to securely hold the whirlchamber against the orifice insert during high pressure spray drying applications, while the Type SSTC, designed for quick and easy assembly, uses a stainless steel spring to hold the whirlchamber against the orifice insert.
