Conventional spray dryers convert liquids into powders in an efficient manner. It is widely used in various fields such as dairy, food and chemical industries and is known for its performance.
Traditional spray dryers are designed for specific products that meet specific industry standards and requirements, and can produce fine powders with particle sizes between 20-300 microns. It is mainly used in the chemical industry, but has also proven valuable in the production of food and dairy products.
Drying Process
Traditional spray dryers are often referred to as single stage spray dryers because the powder will have its final moisture content when discharged from the chamber.
Atomization of the concentrate is carried out by means of rotary atomizers or high-pressure nozzles. Dry air enters at high velocity through the air disperser, ensuring optimum mixing with the atomized concentrate. Instantaneous evaporation occurs as the droplets pass through the drying chamber.
The powder is collected by the drying chamber of the pneumatic conveying and cooling system, and the exhausted air is passed through a filter to separate the remaining particles.
