DRUVATHERM® Reactors are batch-process, high speed reactors.
A three dimensional movement of the product is generated by mixing
elements, adapted to the process, rotating in a cylindrical drum
which is jacketed for temperature regulation. The resultant frequent
contact of the reactants ensures effective reaction and maximum
yield.
DVT
Reactors are built in sizes ranging from 5 liters to 30000 liters.

Mode
of Operation
The high speed mixing elements force frequent contact between the
reactants and intensive contact with the heated or cooled drum wall.
In this way reactions in both homogeneous and heterogeneous phases
can be carried out in any combination of solid/ liquid/gaseous,
whereby the product consistency can be liquid, pasty, lumpy or even
free flowing. High speed choppers fitted to the side of the machine
drum provide an additional mixing effect whilst dispersing the reactants.
