INFORMATION ABOUT THE SWIRL FLUIDIZERTM:
PRODUCT APPLICATIONS:
- Agro-chemicals
- Ceramics, minerals etc.
- Dyestuffs / pigments
- Inorganic / organic chemicals
- Waste product - sludge, sediments etc.
Niro's comprehensive modelling, testing facilities, and industrial
references have contributed to the development of a new generation of SWIRL
FLUIDIZERTM systems with improved ability to continuously handle
even the most viscous liquids in one process stage at very high drying
temperatures.
Niro offers a unique range of process optimisation,
diagnostic, measurement, and asset improvement services. We provide our
customers with high performance process systems and in-depth application
know-how giving an overall distinct competitive advantage to produce at higher
rates, at a tighter product specification, reduced cost and improved
efficiency.

Today's environmental restrictions require a more complex design depending
on the type of product, powder form, residual moisture content in the final
dried product and/or toxicity properties.
Niro has successfully
developed and supplied a number of SWIRL FLUIDIZERTM systems
designed to meet the requirements of our customers and their local authorities
- requirements such as:
- Open, environmentally friendly plants with highly effective components
ensuring emission of clean exhaust process air
- Semi closed plants utilising low oxygen combustion gas as process air
- Semi closed plants, selfinertised and featuring incineration of exhaust air
- Closed cycle concept with Nitrogen purged process gas circuit
PROCESS CONCEPT
- The feed material is homogenised in a feed tank with a vertical agitator
driven from below giving proper access for customer upstream equipment
- Feed material is introduced into the drying chamber continuously and at a
controlled rate
- Process air is heated to the optimal thermal efficiency of the drying
process considering the heat sensitivity of the product in process
- Air disperser with tangential inlet to drying chamber provided with a
vertical rotary disintegrator
- Drying chamber designed specially for optimal feed disintegration and
distribution giving a tight retention time
- Exhaust system is typically selected with a Niro designed cyclonic bag
filter
- For special applications Niro's SANICIPTM with integrated wet
cleaning in place system (CIP) is used
- Product discharge to customer downstream system through a Niro rotary valve
- PLC / PC control system with recipe to ensure reproducible operation
