The spray dryer dries substances by employing a spray, serving as a processing device. The spray dryer mixes a heated gas with an atomized (sprayed) liquid stream within a vessel (drying chamber) to achieve evaporation and produce a free-flowing dry powder with a controlled average particle size that can further be converted into solid form as well. We are a spray dryer supplier based in the USA, along with spray dryers we also supply other processing equipment worldwide.

Some major components of spray dryer unit operation include a method for atomizing a solution or slurry; a source of hot air or an air/gas heater such as a waste flue gas; for achieving the heat and mass transfer a gas/spray mixing chamber with adequate residence time and droplet trajectory distance; a resource for recovering the solids from the gas stream; Install a fan to force the necessary air/gas through the spray drying system.Atomizing the liquid feed in spray dryers creates a unique feature: generating surface area per unit weight.

Process of spray drying:

To comprehend the spray drying process, perform four distinct stages, starting with the atomization of the feed. spray-air contact; drying; separation of the dried product from the drying air.

Major utilization of spray dryers are for food processing and pharmaceutical industries, as well as for ceramic materials,  creating paint pigments, catalyst supports, and also for the use with microalgae. In industrial chemistry and the food industry, spray drying commonly dries organic or aqueous solutions, suspension, dispersion, and emulsion.

The spray drying technique evolved and developed over several decades, from the 1870s to the 1900s period. Several years later, rotary atomizers introduced the first spray dryer, replacing the nozzle atomizers. The first major commercial use of the spray dryer was milk drying. It gained its popularity during the Second World War to decrease the weight of transportation of food and other materials.


The spray dryer is vital in pharmaceutical and food industries, drying liquids into powder and converting it to solid if needed.Spray dryers are extensively used in the food industry, especially in dairy for drying milk, cheese, and other products. The falling film evaporator concentrates milk more efficiently than a spray dryer.

Spray Dryers transform liquids into powders or solids in food, pharmaceuticals, and plant product industries, e.g., coffee, protein, and fruits.
