The liquid is dried, collected and transported for further processing without any intermediate manual handling. Spray dryers are suitable for a wide variety of products and industries, with production capacities ranging from a few grams per hour to 80 tons per hour.
Proper atomization and air distribution are critical to the spray drying process, as both can greatly affect the structure and quality of the product. Spray dryers are often equipped with high-speed centrifugal atomizers to ensure reliable operation. High-pressure nozzle atomization is especially suitable for powders with coarse particle distribution and high bulk density requirements. In the nozzle atomizer, the fines are returned around one or more central nozzles to promote good agglomeration. Two-fluid nozzle agglomeration is typically used in smaller chambers, allowing greater flexibility in particle design and particle engineering for ultrafine and agglomerated particles.
Features
Spray dryers have a number of special design features, including atomizing units and waterless control flow nozzles for easy startup and shutdown, short reject cycles, controllable particle size and an easy-to-control process.
Application field
Spray dryers are widely used in dairy, food, feed, chemical, pharmaceutical and environmental protection industries.
