Niro Spray Dryers #208846 & #203883

The spray dryer design and technology provides the powder producer with the ability to control the powder form through the drying process. The Niro spray dryers are designed to produce properties such as particle size, bulk density, moisture content, solubility, dispersibility etc. exactly as desired by the user. The products are applicable to all pumpable products, whether heat or non-heat sensitive.

The main advantage to powder producers is the ability to control powder form. Niro spray dryers are designed to produce the desired properties: particle size, bulk density, moisture content, solubility, dispensability etc.

Atomization is achieved by feeding liquid onto a high speed wheel. The rotary atomizer is placed in the ceiling air disperser and operates with a vaned atomizer wheel for non-abrasive feeds, or with a carbide bushing wheel for abrasive feeds. Other wheel designs are available for special applications. The particle size of the powder produced is controlled through change of wheel speed.

Agglomerated powders are obtained in systems based upon the integrated fluid bed or belt and a multi-stage concept where moist powder, produced during the first drying stage, forms agglomerates, which are after-dried and cooled in the following stages.

The combination of spray drying and fluid bed drying technologies within the FSDTM and the MSDTMoffers excellent product flexibility and excellent thermal efficiency.
The feed is sprayed down towards the fluid bed by either pressure nozzles or a rotary atomizer. Theagglomeration, whichincorporates finer and recycled material takes place in the fluid bed. Exhaust air outlet is through the roof causing further agglomeration in the spray zone.

Sticky products can be dried successfully, and the concept is ideal for drying heat sensitive products, and improved aroma retention is accomplished.
