Twist & Dry nozzles by BETE are perfect for spray-drying tasks

The BETE Twist & Dry TDK spray nozzle

BETE fluid-handling solutions are available in Canada through John Brooks Company Limited, including the Twist & Dry brand of spray nozzles. Designed for spray-drying applications, these products come in three categories: models for high pressure (TD or TDK), models for high temperatures (TD-HT), and models for low flow (TDL).

Twist & Dry nozzles all have patented locking mechanisms for fast, easy changeouts, and they are also built for easy maintenance.

Fewer components for reduced breakage

All three nozzle variations achieve the spray pattern in the same way: the spray exits on the same axis it enters, and internal channels or vanes cause the fluid to spin. The centrifugal force exerted on the geometry of the exit creates the spray pattern, which concentrates on outer edges with smaller droplets than full-cone.

The TD and TDK models offer wear-resistant spray-dry technology, capable of handling a pressure range from 250 to 10,000 pounds per square inch (psi). The John Brooks Company team recommends them for pressures above 3,500 psi, up to 7,000 psi for the TD-7K variation. TDK features include fewer components in a rugged design, in a one-piece swirl unit for reduced breakage of tungsten carbide pieces, plus complimentary software support to simplify swirl-unit and orifice-disk selection. Advantages include higher yield capacity, safe and leak-proof function, and low additional cost.

Also known as a whirl nozzle, the TD model is an axial hollow-cone spray nozzle that offers uniform distribution of relatively large droplets. Tangential or axial units have internal vanes that cause fluid to whirl. The hollow-cone pattern facilitates heavy concentration of droplets around the spray cone’s edge; little or no liquid is deposited in the middle of the cone. The spray pattern is a medium-to-low-impact pattern that is harder-driving than misting or full-cone patterns, but with lower impact than flat-fan or solid-stream patterns.

Ideal for processing milk, other foods, and chemicals, TDL whirl nozzles are low-flow, compact-carrier body-spray models with lower flow rates, two-piece bodies for simpler maintenance, and female-threaded or butt-weld pipe connections. These units are perfect for small-scale applications and pilot tests.
