INTEGRATED FILTER DRYER, IFD™: IMPROVED PERFORMANCE AND IN-PLACE POWDER RECOVERY
The Multi-Stage Dryer MSD™/ FSD™ concept has been widely used in the food and dairy industries since GEA 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 - IFD™
The Integrated Fiter Dryer - IFD™ - features an integrated fluid bed and filter arrangement. GEA Niro has further developed and refined the versatility and success of the MSD™ by introducing the CIP-able SANICIP™ bag filter. The location of the filter assembly inside the drying chamber improves powder quality and gives total in-place powder recovery and cleaning capability. The combination of the integrated fluid bed and filter arrangment simplifies powder handling, because the need for external cyclones, bag filters, and fines recycling has been eliminated. 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 IFD™ concept especially attractive to producers where hygiene is a first priority.
IFD™ ADVANTAGES
- Improves 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
- Lower energy consumption
The Integrated Filters reduce space reguirements and whether using the SANICIP™ cleaning system or not, an integrated filter will enhance performance for a long range of products.
