Single-stage spray drying solutions and use advantages

- Jul 02, 2018-

Single-stage spray drying has a fast drying speed during the operation process. After the atomization, the surface of the spray drying is increased. When the spray drying is performed, it directly contacts the hot air, and then the product quality is good. When the spray drying is performed, the instant dissolving property is restored. Good sex, and can maintain the original color, aroma, taste of food, less nutritional loss.

The single-stage spray-drying system can generally be in one or more stages and is directly integrated with the fluidized-bed treatment when used, typically providing a fluidized-bed system for post-drying, agglomeration, conditioning and cooling. The spray drying system can evaporate from a pilot scale to 20,000 kg/h.

Single-stage spray drying is generally the most common and flexible solution for a full range of products in the dry food and chemical industries. During the process of operation, it will effectively atomize liquid materials into small droplets to convert them into dry ones. Free flowing powder. The main method of atomization is a centrifugal rotating wheel or a hydraulic high pressure nozzle. The final product produced has an average particle size in the range of 25-100 microns.

Single-stage spray drying will be equipped with a proprietary hot gas distributor so that it is possible to ensure optimal contact with the drying medium in the drying chamber to a certain extent. The liquid feed is dried in a drying chamber to a fine powder and discharged from the base of the cone or together with the exhaust gas to the main separator, a cyclone separator or a dust filter. The drying configuration is mainly parallel flow but can be provided in other configurations depending on the specific application. For thermally sensitive and difficult-to-dry products, integrated cooling of cabinets, roofs and hot gas distributors is provided.
