Method for destroying harmful microorganisms in liquids by short-time high temperature heating

摘要

In a method of destroying harmful microorganisms in liquids by short term high temperature heating of the liquids in micro heat exchangers formed by stacks of metal foils having parallel microchannels, in a first step, the liquid is rapidly heated in a micro heat exchanger with a gradient of at least 200° K/sec, then is maintained at the high temperature for a time period of <2 sec and is finally cooled again in a micro heat exchanger with a gradient of at least 200° K/sec.
