Description

Mini SDX® Spray Drying Nozzle produces a hollow cone spray pattern with relatively uniform droplet distribution. Available with flow rates from 24 to 208 L/h, depending on nozzle size, and nominal spray angles from 70° to 75°, the Mini SDX® Spray Drying Nozzle is suitable for applications requiring fine atomization, low operating pressures, and extended service life. The unique swirl chamber design reduces friction loss compared to conventional slotted distributor nozzles, helping to improve atomization performance while reducing pump and nozzle wear.

Spray Characteristics:
Produces a hollow cone spray pattern with relatively uniform droplet distribution and a nominal spray angle of 70°-75°. It provides fine atomization at lower operating pressures than conventional slotted distributor nozzles. Flow rates range from 24 to 208 L/h, depending on nozzle size.
Construction and Materials:
Five-part construction comprising a nozzle body (303 Stainless Steel), orifice disc (Tungsten Carbide), distributor/swirl chamber (416 Stainless Steel with Ceramic swirl chamber), retainer (Brass or 416 Stainless Steel), and Viton O-ring seal. The patented single inlet swirl chamber minimizes plugging and maximizes particle uniformity. The Viton O-ring design allows assembly and disassembly without tools, while the pressed-in orifice disc protects against damage during operation. Available with 1/4" NPTF and 3/8" NPTF adaptor connections in 303 Stainless Steel.
Maximum Recommended Pressure:
350 Bar.G
