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.
