A spray drying system includes a feed pump an atomizer an air heater a drying chamber and a means for separating and collecting powder from the exhaust air Figure 12In the typical operation the liquid is pumped into an atomizer which disperses the liquid into fine drops and into a chamber of heated air.
Along with a full line of industrial air heaters we offer turnkey construction project management and spare parts support for all PCC supplied products.
An appreciable amount of heat is lost with exhaust airSpray dryer is bulky and also expensive to installIt is difficult to clean after useIt has a low thermal efficiency that is a lot of heat is wasted during operation.
Apr 01 2008nbsp018332The dryers have relatively short residence timesVarying the gas velocity within the dryer can alter the residence time inside the dryerSpray dryers typically employ induceddraft fans to extract the moistureladen air from the systemIn some instances special fans are installed to achieve dryerspecific operations such as air sweeps.
By definition the air inside a spraydrying process vessel— be it a chamber cyclone or baghouse—is moist and warm while the temperature outside the vessel is cooler.
Feb 22 2021nbsp018332Diagram of a Spray Drying SystemSpray dryers use an atomizer to feed liquid into a drying chamberWhen the small drops of liquid enter the chamber they are subjected to hot air which turns the feed into powder by means of water evaporation.
Heat may be supplied by convection direct dryers by conduction contact or indirect dryers radiation or volumetrically by placing the wet material in a microwave or radio frequency electromagnetic fieldOver 85 percent of industrial dryers are of the convective type with hot air or direct combustion gases as the drying medium.

A spray dryer single or multistage uses hot gas to process a slurry or liquid to produce a dry powderThis is especially common in food and pharmaceutical manufacturingFaster than most of the other dryer options this process atomizes the liquid or slurry through a spray nozzle and into a hot air or gas stream.
Gain competitive advantages in spray drying with an HID™ Air Distributor High Intensity Drying technologyUp to 20 higher capacity compared to a conventional air distributorThe multistage HID™ Air Distributor is more efficient – energy consumption can be reduced with up to 10The different inlet air temperatures and.
Spray drying technology centres around a large dehumidifier drying tower complete with a humidity control system that supplies dry air for this spray drying towerMany businesses and industries use this technique – and for good reason The spray drying approach offers a superior way to dry large quantities of a variety of products in a relatively short space of time.
Systems to control the waste stream from processes where a crude or semifinished substance such as metal oil or sugar is converted refined into a finished or highergrade product.
The combustion product is not directly used to heat the airHence the transfer of heat from the combustion product takes place through a combustion mediumIn the indirect heaters the heat generation and transmission take place in the stoveIn the first type hot air is passed through a metallic pipe and heat is transferred to the air outside the tubeIn the second type the hot air is made to flow outside the pipe.
The drying air enters through the air disperser at a high velocity ensuring optimal mixing with the atomized concentrateEvaporation is instantaneous taking place as the droplets pass through the drying chamberThe powder is collected from the drying chamber in a pneumatic conveying and cooling system.
The new GEA HotSwirl Indirect heaters provide reliable hot air at a consistent volume and temperature for GEA’s range of spray and fluid bed dryersGEA SANICIP174 II bag filter The new SANICIP174 II bag filtration system patent pending for food and dairy spray dryers offers valuable operational benefits in terms of reliability cost savings.
The spray drying process creates fine dust particles which can be filtered and recuperated thanks to sanitary product recoveryAs a result the energy efficient air filter system the economic product recovery and the powerful heat recovery save operating costs and lead to a short payback periodThe dedusting of the spray dryer for product.
