 OTHER TYPICAL PRODUCTS WHERE THE NIRO DRYING TECHNOLOGY IS USED:

Alkyl-Aryl Sulphonates Dispersing agents Emulsifying agents Enzymes Fatty alcohol sulphonate Mono- and dipotassium orthophosphate Nitrilo tri-acetic acid salts Optical brightener Phosphates Hand soap Sodium lauryl sulphate Sodium perborate Sulphonates Tetra potassium polyphosphate

SPRAY DRYING (TOWER PRODUCTS):

The spray drying processes can be designed with co-current, counter-current or mixed airflow patterns. With the feed being atomised either by pressure nozzle, two fluid nozzles or rotary atomiser. The type of feed varies between melts, solutions and slurries. The drying chamber is designed to insure the needed air flow and product residence time, being different from product to product.

The exhaust air can be designed with cleaning in cyclones, bag filters and scrubbers. In some cases the bag filters can be installed in the top of the drying chamber and thereby minimising the plant area consumption and the need for an external fines return system is avoided.

GRANULATION (NON TOWER PRODUCTS):

The Niro Continuous High Shear Granulator (HECTM Series), has been specially developed to meet industrial requirements of converting dusty, light powders into high density free-flowing granulates. The HECTM handles a wide variety of powders. Initially developed for the detergent industry to produce compact powders with densities ranging from medium to high density.
