Inventor: YAN ANDERSSON
IPC: A23L3/3445
Filed: 1990-11-06
Granted: 1995-05-27
Abstract: A method of producing a gaseous, hydrogen peroxide-containing sterilisation fluid displaying good, uniform sterilisation properties, by vaporisation of liqueform hydrogen peroxide which is injected intermittently in finely-divided form into an air current serving as vaporisation agent which is kept at a constant or but insignificantly varying elevated vaporisation temperature. The even vaporisation temperature of the air current is ensured in that the air, prior to the vaporisation, is heated by heat exchange with a heating element (11) of large mass (thermal capacity) and large heat exchange surface area which is kept at the de- sired elevated temperature by regulated energy supply to the heating element and which, during breaks in vaporisation between the intermittent injection of the liqueform hydrogen peroxide, is heated with the aid of heat stored in the heating element.
