Description

SDX® III Spray Drying Nozzle produces a hollow cone spray pattern with uniform particle size distribution, even at low operating pressures. Designed for spray drying and atomization applications, the SDX® III Spray Drying Nozzle incorporates a patented single-inlet swirl chamber that improves product uniformity, particle density, and solubility. The optimized swirl chamber design reduces friction losses, allowing operation at lower pressures than conventional slotted distributor nozzles while extending pump and nozzle life. The O-ring sealed construction enables assembly and disassembly without tools, simplifying maintenance and reducing downtime.

Spray Characteristics:

Produces a hollow cone spray pattern with uniform particle size distribution and fine atomization over a wide operating range. Flow rates are controlled within ±5% of rated capacity at 69 Bar.G and within ±5° of rated spray angle when tested with water. The patented single-inlet swirl chamber improves product uniformity, density, and solubility while reducing operating pressure requirements by approximately 10-20% compared with conventional slotted distributor designs.

Construction and Materials:

Six-part construction consisting of body, orifice seal, orifice disc, swirl chamber, end plate, and adaptor. O-ring seals allow assembly and disassembly without tools. Bodies and adaptors are manufactured from 316 Stainless Steel. Orifice discs are available in Tungsten Carbide, Chrome Carbide, and Ceramic. Swirl chambers are available in Hardened Stainless Steel, Tungsten Carbide, and Ceramic, while a combined Tungsten Carbide swirl chamber/end plate option is also available. End plates are available in Tungsten Carbide and Ceramic. O-rings are available in Silicone or Viton. The round-bodied design minimizes product build-up and simplifies maintenance.

Maximum Recommended Pressure:

350 Bar.G.

Maximum Design Pressure:

350 Bar.G.

Maximum Design Temperature:
150˚
Ordering Instructions:

Please indicate all component parts and materials when ordering.

Assembly Procedure:

  1. Place Nozzle Body (A) thread side up on a flat surface
  2. Make sure the Orifice O-Ring (B) is pressed snugly to the Nozzle Body (A)
  3. Place Orifice O-Ring (C) beveled side down into the Nozzle Body (A)
  4. Use a finger to align the orifice into recessed area in the Nozzle Body (A)
  5. Place Swirl Chamber (D) on top of Orifice Disc (C) either way up the direction does not affect functionality (W0138 will go one way only)
  6. If you require an End Plate (E) place it circular side down over Swirl Chamber (D) with square side of the end plate on top
  7. Make sure Adaptor O-Ring (F) is on Adaptor (G)
  8. Screw Adaptor (G) onto Nozzle Body (A) and hand tighten only
  9. Finally, ensure the complete assembly does not rattle
