CryoRoll for Recycling Industries

Continues Freezer for particles such as tyre chips

Ultra low cooling and mixing

The CryoRoll drum freezers consist of a sloping cylindrical drum, which is rotating around its axis.
Product and cooling medium are loaded continuously at the highest entrance point of the drum. By the rotating movement, both are intensively mixed while, at the same time, sliding to the lower exit of the drum. The stirring movement and the mixing prevent products from clumping together. Special paddles can be built in to ensure this happens.

Both liquid nitrogen (LIN) and liquid carbon dioxide (LCO2) can be used as cooling liquid.
Exhaust fans at inlet and outlet extract the residual gases.


CryoRoll drum freezers are best used for rubber chips of tyres, cables and other products.

Even very sticky products can to frozen, in that case we can cover the inner wall of the drum with a non-adhesive coating such as PTFE.

Features and Benefits
