Versatile Spray Drying for the Chemical, Pharmaceutical, Food and Dairy Industries

IFDTM: Improved Performance and In-Place Powder Recovery
The Multi-Stage Dryer MSDTM/ FSDTM concept has been widely used in the food and dairy industries since Niro obtained the first patent in the early 1980s. The drying principle is used to produce a wide range of free-flowing powders, agglomerated, and granular dry materials of low dust content, many of which are difficult to produce on other spray dryer types.


The Integrated Filter Dryer - IFDTM
Niro has further developed and refined the versatility and success of the MSDTM by introducing the CIP-able SANICIPTM bag filter. This combination is used in the new Integrated Filter Dryer - IFDTM - which features an integrated fluid bed and filter arrangement. The location of the filter assembly inside the drying chamber improves powder quality and gives total in-place powder recovery and cleaning capability. It also simplifies powder handling as it eliminates the need for external cyclones, bag filters, and fines recycling. Prototype testing has shown that the location and operation of the internal filters enhance control over particle formation and therefore over the quality specification. The compact design reduces the amount of equipment in contact with the product. Consequently, cleaning is easier making the IFDTM concept especially attractive to producers where hygiene is a first priority.
