Powdering while drying
The CRIOX System, a great success patent of ITALVACUUM,
is a rotary vacuum dryer able to totally extract water
and other solvents from the wet powders coming from
filtering or centrifugation.
The central body of the CRIOX System is made of a double
cone chamber with a variable speed of rotation, characterized
by soft lines without edges and sharp corners. During
the system rotation, this structure allows the continuous
revolution of the mass to be dried and a homogenous
and delicate mixing.
Within the drying chamber there are two lump-breaker
units with variable speed. During chamber rotation,
the lump-breaker group goes alternatively in and out
of the product, cleaning itself when not in contact.
The lump-breaker groups break at a first stage the possible
wet blocks inside the mass and during the drying phase
they mill and powder the product.
For bulk products this means an end product ready to
be stored, while for the other products this means a
correct final particle size distribution.
The mechanical action of the chamber and the lump-breaker
units allow to increase the surface of the product exposed
to evaporation and therefore to carry out the vacuum
drying in a very short time and with a temperature on
the average much lower than in any other dryer.
This is an advantage for the purity of the most delicate
thermo sensitive products, as it avoids their degradation
and respects their chemical structure.
Furthermore the moisture extraction is certainly higher,
because the mass core is constantly penetrated by the
lump-breaking knives that increase the surface exposed
to evaporation.
