The IFD™ Integrated Filter Dryer combines an integrated fluid bed and filter arrangement.
Filter Dryer: Versatile Spray Drying for the Chemical, Pharmaceutical, Food and Dairy Industries
Integrated Filter Dryer: Improved Performance and In-Place Powder Recovery
The Multi-Stage Dryer MSD™ and the FSD™ have been widely used in the food and dairy industries, since Niro obtained the first patent in the early eighties. 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 types of spray dryers.
The Integrated Filter Dryer - IFD™
Niro has further developed and refined the versatility and success of the MSD™ by introducing the CIP-able SANICIP™ bag filter. This combination is used in the new Integrated Filter Dryer - IFD™ - 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 proven that the location and operation of internal filters enhance control of particle formation and thereby quality specification. The compact design reduces the amount of equipment in contact with the product. Consequently, cleaning is much easier, making the IFD™ concept especially attractive to producers where hygiene is top priority.
IFD™ advantages include:
- Improved powder quality
- Total in-place recovery of powder
- Features integrated fluid bed
- Simplifies CIP operations
- No handling of product outside drying chamber
- Compact plant layout
- Reduced noise level
- Less energy consumption
