Spray Drying Technical Information SDX® Spray Dry Nozzles The Critical Factors That Affect Spray Quality The Atomiser Delavan recognises that at the ‘heart’ of any spray dryer is the atomiser, small in size, big in importance. Therefore installing the right atomiser is an essential step to ensuring spray drying success. The atomiser must fulfil several important functions: 1. It must disperse the feed material into small droplets, which should be well distributed within the dryer and mixed thoroughly with the hot gas 2. The size of the droplets produced must be compatible with the required product...

Liquid Properties The properties of the feed stock are directly related to the finished particle size. Therefore density, viscosity, percentage solids, abrasive awareness and any other characteristics all need to be considered. The liquid properties should be established at the temperature corresponding to the liquid in the nozzle. Feed stocks are often sprayed at elevated temperatures to decrease viscosity, thereby improving atomisation. The effect of each liquid property on droplet size is usually established by actual test, however Delavan’s field experience shows that these effects can be...

Spray Drying Product Range SDX® Spray Dry Nozzles Product Overview Delavan Spray Technologies has been the leading innovator and supplier of atomising nozzles for the spray dry industry for more than four decades. This tradition started with the original SDX® Nozzle and continues with the latest SDX® family of nozzles. This product line, specifically designed for the spray drying industry, includes five centrifugal pressure nozzles: the Mini SDX®, Compact SDX®, SDX®, SDX® III and SDX® V. Each of these five products is built on Delavan’s unique single inlet spiral swirl chamber design and highly...

Mini SDX® Nozzle The Mini SDX® is a low-flow, easy to assemble nozzle, offers the same performance and technology as our larger SDX® products, but for lower capacity applications. Hand tighten assembly with a maximum operating pressure of 345 BAR/5000 PSI and temperature of 149° C/300° F. Maximum operating temperature of 149° C/300° F.

SDX® V Swirl Chambers Delavan has introduced an alternative design of Swirl Chamber especially for the SDX® V nozzle. The end plate is no longer integrated but is supplied as a separate component. This new option addresses occasions where increased wear on the bottom of the standard chamber occurs, caused by cavitation or abrasive particles. In certain circumstances, the bottom of the Swirl Chamber wears out before the walls, or the inlet throat. With the new design, the separate end plate can be replaced and the ‘open’ Swirl Chamber can be reused. There is also the option to use end plates with...

Compact SDX® Nozzle The Compact SDX® is a new and improved nozzle, featuring easy to assemble, longer lasting parts. It mimics the Mini SDX® in size but has a higher flow range with more spray angles. Hand tighten assembly with a maximum operating pressure of 345 BAR/5000 PSI and temperature of 149° C/300° F. Maximum operating temperature of 149° C/300° F. Removal Tool Part No. W203080012.
