NTD (Non Tower/Agglomeration) process

A Non Tower Detergent powders production plant based on proprietary agglomeration technology, also based on the special Kettemix reactor, for the production of medium-high density detergent powders

The NTD Non Tower Detergent production technology, based on the KETTEMIX reactor/granu-lator, has been developed by Desmet to meet the worldwide market requirements for detergent powder production with reduced energy demand and manufacturing costs, without limitation to the physical, chemical and performance characteristics of the products.

Desmet’s know-how for the manufacture of high quality detergent powder and its unique expertise achieved with the supply of more than 550 spray drying plants all over the world have merged into the design of this reliable, easy to operate NTD plant.

The Desmet NTD process is based on the principle of agglomeration between solid and liquid components.

The process includes the following steps:

• Solid and liquid raw materials handling and dosing
• Dry neutralization and agglomeration in the Kettemix reactor
• Product drying/cooling in fluidized bed conditioner
• Post addition of thermo-sensitive components
• Detergent powder sieving, perfuming and distribution to packaging

The process equipment can be sized for production capacities from 2 to 20 t/h of detergent powder.

In case of a plant capacity over 5 t/h, the dosing of solid components can be performed by a fully automatic continuous dosing system, while for lower capacities, a blend of solid components is continuously dosed to the process after a batch type pre-mixing.
