Spray Dryer
Conventional NIRO® Spray Dryer
The conventional NIRO® Spray Dryer turns liquid into powder in a highly efficient manner. It is used within fields as diverse as the dairy, food and chemicals industries where it has won renown for its performance.
The drying process
The conventional NIRO® Spray Dryer is often referred to as a one-stage spray dryer as the powder will have its final moisture content when discharged from the chamber.
Atomization of the concentrate takes place via either a Rotary Atomizer or high-pressure nozzles. The drying air enters through the air disperser at a high velocity, ensuring optimal mixing with the atomized concentrate. Evaporation is instantaneous, taking place as the droplets pass through the drying chamber.
The powder is collected from the drying chamber in a pneumatic conveying and cooling system. The exhaust air passes through a filter separating out the remaining particles. For a final drying/cooling of the product, a VIBRO-FLUIDIZER® fluid bed can be connected with the base of the drying chamber. By choosing this drying mode, the plant will become a two-stage dryer with improved energy consumption, increased capacity and, in some cases, even resulting in improved product quality.
