IIT designs and manufactures complete plants and equipment for detergent powder production both by spray drying or by dry mixing & granulation. The first technology is most preferred for high quality detergents, while the latter is most preferred for low price detergents.
Spray drying plants
Spray drying is the predominant technology to produce heavy and light duty detergents powders for both machine washing and hand washing. This technology allows to produce powders with accurate composition and granulometry, with the possibility to include Anionic and Non Ionic Surfactants in the formula. The final product features optimal solubility and a bulk density of 250÷450 g/l.
The output capacity of IIT spray drying plants can be in the range from 1000 kg/h to 20000 kg/h and more.
The standard IIT plants include the equipment for:
raw materials storage and transport
solid and liquid raw materials dosing
slurry preparation
spray drying
exhaust air filtration and recycling of fines and scraps
post addition
packing
The raw materials usually employed are: Dodecyl Benzene Sodium Sulfonates, Fatty Alcohol Sulfates, Soap pastes or powders, Phosphonic Acid, Maleic, Acrylic Acids, Sodium Carbonate, Sodium Silicate, Sodium Tripolyphosphate, Zeolite A, Sodium Sulfate, Sodium Perborate and others.

Dry mixing and granulation
The dry mixing and granulation process allows to produce low price powder detergents, thanks both to the low energy required by the process, as well as to the high bulk density of the final product (550÷750 g/l), which allows to reduce the costs for storage, transport and packing.
The output capacity of IIT plants for dry mixing and granulation spans in the range from 500 kg/h to 10000 kg/h and more.
Standard IIT plants based on this process include the equipment for:
raw materials storage and transport
solid raw materials dosing and premixing
liquid raw materials dosing
continuous neutralization-granulation
continuous drying and cooling
exhaust air filtration and recycling of fines and scraps
