INFORMATION ABOUT THE SWIRL FLUIDIZER™


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 FLUIDIZER™ 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 FLUIDIZER™ 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 SANICIP™ 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
