GEA Niro offers a broad range of solutions for drying of detergents, surface active agents and other ingredients, especially designed to meet your agglomeration, granulation and drying needs.
Having a long track record within drying plants for detergents, surface active agents and other ingredients, we know what it takes to make them in solid form; both in terms of product requirements and requirements to the plant in terms of efficiency, safety and environmental compliance.
GEA Niro’s range of drying solutions includes spray drying, fluid bed drying and cooling and agglomeration/granulation units - all designed to meet the precise needs of each customer:
- Spray Dryers
- GEA Niro’s single-stage spray drying systems for production of fine to medium coarse powders. For a very uniform particle size, the spray dryer can be equipped with the GEA Niro NARROWSPAN™ atomizer wheel.
- Continuous High Shear Granulator HEC™
- The continuous high shear granulator HEC™ (High Efficiency Compactor) is designed to produce granular products by fluid bed spray technique. It meets the industrial requirements of converting dusty, light powders into free-flowing granulates in many industrial applications including detergents.
We meet the strictest requirements to efficiency, safety and environmental compliance
Since many detergents and surface active agents include hazardous ingredients, GEA Niro’s drying plants are designed to meet the strictest standards when it comes to explosion and emission control systems. GEA Niro’s vast experience within these areas is unequalled and also an invaluable aid when it comes to complying with international safety directives like ATEX, other European safety directives and/or local regulations.
GEA Niro offers:
- Plants with highly effective filters and scrubbers to ensure exhaust of clean process air
- Semi closed plants utilising low oxygen combustion gas as process air to prevent explosions
- Semi closed plants, self-inertised and featuring incineration of exhaust air
- Closed cycle plants utilising nitrogen as process gas circuits
- Pressure shock resistant plants designed with either suppression or pressure relief to protect the equipment and personnel
Cleaning-in-place (CIP) systems, semi- or fully automatic, are available for all GEA Niro plants. Efficient cleaning allows for more uptime and makes colour interchangeability easy and efficient.
Examples of drying solutions for detergents and surface active agents
A wide range of detergents and surface active agents are dried using technology from GEA Niro. The right solution depends on the feedstock and the powder properties in demand. For drying of detergent and surface active agent slurries, GEA Niro spray dryers with rotary atomizers or nozzles are an excellent choice. They provide a fine powder.
GEA Niro’s spray dryer type Fluidized Spray Dryer, FSD™, is ideal as it provides a dust free powder with superior flow ability and solubility. This helps improve the performance of the dyes and of the detergents and ingredients. Additional agglomeration and granulation can be obtained with the FSD-GRANULATOR™ (patent pending.)
GEA Niro’s fluid bed technology is ideal for post-drying and cooling of detergents and surface active agents.
Examples of other detergents and surface active agents dried on technology from GEA Niro:
- Alkyl-Aryl sulphonates
- Dispersing agents
- Emulsifying agents
- Enzymes
- Fatty alcohol sulphonate
- Hand soap
- Optical brighteners
- Phospates
- Sodium lauryl sulphate
- Sodium perborate
- Zeolites
- Sodium carbonate
- Etc.
