Powdering while drying
CRIOX System: The only vacuum rotary dryer with electric lump breakers
CRIOX System, a great success patent by 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 and a homogenous and uniform 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. 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.
Lump breakers are electrically operated. CRIOX System is the only rotary double cone dryer of this type currently on the market. This is a crucial feature, as electric motor-driven lump breakers offer exclusive performance and benefits, including:
- Rotating speed control
- Scheduling of operating cycles
- Constant torque with changing speed
- Absorption control
- Ventilated cooling.
Moreover, electric lump breakers ensure:
- Reliability and durability, also in heavy-duty conditions
- Low maintenance.
The total absence of pneumatic circuits avoids the risk of lubricated air pressure release inside the drying chamber and surrounding environment, thereby ensuring utmost safety throughout the production process and the highest quality of dried material.
CRIOX System peculiarity
CRIOX is multi-product allowing its use with the widest range of possible products with crystalline or amorphous structure.
CRIOX is versatile: specific solutions have been studied for the automatic loading and unloading of the product and also for washing, cleaning through and inspecting the plant before changing the type of batch. The SWAB test is also easier to carry out.
CRIOX is multi-purpose: it can also be used as an effective fast blender or homogenizer; in most cases it doesn’t require the subsequent use of the mill and it can also be used as a granulator. It ensures:
- In-cycle adjustable product pulverization without agglomerates
- Perfect homogeneity and uniformity of the dried batch.
CRIOX is completely safe for the operators, the product and the environment, being designed and manufactured according to the highest safety standards for chemical-pharmaceutical productions and in compliance with the even more severe FDA and ATEX norms.
