Device and method for disinfecting materials

摘要

The equipment treats the material (15') in an enclosure (15) with ozonised air from a generator (5') and accumulator (16). Residual ozone leaving the enclosure is eliminated preferably by an electric heater (10') and a catalytic destructor (10"). A vacuum is maintained in the enclosure by a pump (9) in the outlet from the destructor. An injector valve (12) abruptly supplies more ozonised air when the pressure (13) falls below a threshold. A safety valve (7) releases air through an auxiliary ozone destructor (8).
