Anhydro Spray Drying Plants for the Dairy Industry

A Question of Accuracy, Efficiency, and Flexibility Spray drying is a highly cost-effective method of obtaining powder from heat-sensitive liquids such as milk and whey while retaining valuable nutrients, aromas, and flavours. Spray drying is a continuous process, which converts almost any pumpable liquid into a free flowing powder. The liquid, which can be preheated in order to reduce energy consumption in the drying process itself, is sprayed via an atomizer into a drying chamber, in which it is evaporated. The solids content is further processed in an integrated and/or external fluid bed....

Typical Product Applications A N H Y D R O ATO M I Z E R S SPX FLOW offers two basic types of atomizers which disperse feed liquid into the hot air in the drying chamber: With the Anhydro spray drying equipment you can produce a wide range of dairy powders. • Centrifugal atomizers, which accelerate and atomize the liquid feed using centrifugal force in a rotating disk. They are suitable for most dairy applications, especially Infant Formula crystallized products. Qualities such as easy dosing, good reconstitutional • Nozzle atomizers, which force properties, dustless powders, the liquid feed...

A N H Y D R O S P R AY D RY E R S Two drying principles are relevant for the dairy industry. The Anhydro Conical Spray Dryer (CSD) with air outlet at the base of the ­ hamber, and the Anhydro Triple-A Spray Dryer with air c outlet at the top of the chamber. Each type offers the following options: • Single-stage spray dryers with product outlet at the base. • Two-stage spray dryers sending ­ roduct to an external fluid p bed dryer and/or cooler. • Multi-stage spray dryers sending product to an integrated fluid bed, and then into an external fluid bed dryer and/or cooler.

Optimised Yield and Efficiency Separation of powder from the hot air leaving the drying chamber increases yield by limiting powder losses, and Automated process control is essential in order to optimise ensures compliance with environmental legislation by reducing key process settings such as feed rate, temperature, pressure, emissions. Efficient heat recovery is also a key factor in plant residence time, particle size, moisture content, bulk density, etc. The Anhydro spray drying plant is controlled from numbers of operator stations, providing the operator with an end-to- end overview of all...
