From Shape to Result

From the structure to the smallest detail: everything in the CRIOX® System industrial rotary dryer is designed to ensure that the entire production process delivers maximum results. Starting with the shape of the central body: the rotating biconical chamber of the rotary dryer, characterised by soft lines, facilitates the complete and continuous revolution of the mass to be dried and allows an extremely homogeneous and uniform stirring compared to a classic rotary drum.

The rotation speed of the chamber is adjustable, allowing gentle to moderate agitation.

CRIOX® System is the biconical rotary vacuum pulveriser dryer ideal for drying moist masses from centrifugation or filtration processes. Thanks to two powerful groups of electric lump-breaking knives, CRIOX® System completely crushes any possible block of product, thus obtaining dry powders ready for riddling and bagging.

Multi-product industrial dryer, can be used with the widest range of products possible both with crystalline and amorphous structures, effective mixer or homogenizer also used as a wet granulator, safe for operators, the environment and the product, because it is designed and built in compliance with European Directives CE, ATEX and in compliance with the increasingly stringent FDA regulations and cGMP good manufacturing standards

Main Features

Complete revolution and lump breaker

The biconical shape of the rotating chamber of the dryer is characterised by soft lines, facilitating complete and continuous revolution of the mass to be dried and allow an extremely homogeneous and uniform stirring.

The maximum industrial drying result is guaranteed by the presence inside the rotary biconical chamber of two powerful units of lump-breaking knives.
The exclusivity of the CRIOX® System patent allows to increase the product surface exposed to evaporation and to increase the effectiveness of the system.

Combined action

Thanks to the rotation of the chamber, the lump-breaking knives pass through the product alternately and self-clean when they emerge. Their action offers a twofold advantage: it prevents the formation of product agglomerates and allows the dried mass to be ground and pulverised during the last stage of the process with a controlled grain size. 

Acting in the mass of the product to be dried, the lump breakers significantly reduce the drying time and ensure extremely low residual moisture levels. Furthermore, they allow to operate at low operating temperatures, to the advantage of the purity of the most delicate and thermolabile products, avoiding their degradation.

Electric engines

CRIOX® System is the only biconical rotary vacuum dryer on the market that allows the lump breakers to be operated electrically. This is very important, because lump breakers powered by electric motors provide unique performance and benefits:

  • control of rotation speed and constancy of the selected speed
  • programming of activation cycles
  • constant torque as speed varies 
  • absorption control
  • reliability and long life, even in heavy-duty applications
  • low maintenance
