Design Features of the Twist & Dry® (TD) Spray Drying and Hollow Cone Nozzle

  • Patented locking mechanism for quick and easy change-out and maintenance

High pressure applications:

  • Choose TD-K with PEEK backup ring to operate at high pressures for greater yield capacity
  • HT body with Carrier #7

High temperature applications:

  • TD/TD-K bodies with silicone O-ring
  • HT body with Carrier #7
  • Female pipe thread or butt-weld connections
  • Hand tighten, no special tools required
  • Orifice size: 0.034" through 0.157" (0.864 mm through 3.99 mm)
  • Interchangeable swirl and orifice discs for variable patterns and flow rates
  • Drip Pro check valve available upon request
  • Multiple grades of tungsten carbide to suit application needs
  • Same day shipping of wear parts
  • Clog-resistant design
  • Easy to maintain

The Twist &Dry® component system was developed for the spray dryer industry. The TD-K was next developed as an innovative solution to expand spray dryer capacity up to 10,000 psi. The patented locking system locks components into place prior to installation. There are many interchangeable swirls and orifice disks available for varying the flow rates of the nozzles. Many materials are also available to allow for high temperature usage without leakage.

SPRAY SET-UPS

Twist & Dry nozzles have almost 1,000 different combinations of swirl and orifice discs to provide exactly the right flow rate and angle for your needs. The spray angle and flow rate are determined by the swirl/orifice setup—a specific combination of one swirl disc and one orifice. Spray angle is determined by the orifice geometry. Carriers and bodies differ in both material and design to accomodate both high temperature and pressure. The robust design allows for many material choices and combinations.

The Twist & Dry is a BETE original design that answers the needs of the spray drying industry. The BETE design offers superior performance as well as an innovative patented locking mechanism. Replace the wear parts of your spray dry nozzles without turning the lances upside down!

The BETE Twist & Dry is designed with the operator in mind. If you operate and maintain a spray dryer, you know just how difficult it can be to replace the nozzle wear parts.

These unique features of the Twist & Dry design make replacing nozzle wear parts much easier:

  • Fewer parts; rugged design: one piece swirl unit greatly reduces breakage of tungsten carbide pieces 
  • Easy assembly: the BETE Twist & Dry locking system keeps the swirl chamber and orifice locked into position during assembly
  • BETE provides software support: users of the Twist & Dry receive free-of-charge computer software that greatly simplifies selecting the correct swirl unit and orifice disk.
