Date Sep. 17, 1992The method for cleaning of heat exchangers after passage of fluid, pulpy material through the heat exchangers is characterized by the fact that the heat exchangers are exposed to a cip (cleaning in place) treatment with a solution of an enzyme preparation, which contains pectolytic, cellulolytic and hemicellulolytic activities. This method for cleaning of heat exchangers is less time and energy consuming and more environmental-friendly than the hitherto used methods of this kind.</p> |
