The Agglomeration
with Post Addition Plant is recommended when a high bulk density
detergent with high active matter content has to be produced
from a base powder of low bulk density.
Spray Drying
combined with Agglomeration with Post Addition can produce powder
detergents up to 600-800 g/l of bulk density. A base powder containing
almost all the anionic surfactants is produced in the Spray Drying
plant. The agglomeration through the addition of liquids and
solids increases the product flow charateristics and the bulk
density.
Sodium carbonate,
zeolite or STPP, and non ionics are mixed with the base powder
into a special agglomerator.
The heat sensitive components and the minors (sodium carbonate,
enzymes, perfume, Tetra-Acetyl Ethylene Diamine, antifoam, blue-specks
etc.) are incorporated in the detergent after agglomeration in
a final mixer.
By the Agglomeration
with Post Addition Plant the overall capacity of a Spray Drying
plant is significantly increased up to almost twice the nominal
capacity.
The Agglomeration with Post Addition Plant includes:
