摘要

according to a method inhibiting bacterial growth in an installation for refrigerating or freezing of food, the installation (1) comprises a housing (2) in which are arranged the means (3) for cooling food, and a cycle of operation of work period, during which the cooling means (3) are active.as well as a rest period during which the cooling means (3) are inactive, and the installation can be cleaned, the cleaning of the system temperature rise above a temperature required to kill bacteria.in addition, the air pressure in the system is kept higher than the ambient pressure, at least during the entire period of rest, for delivery of air free from bacteria.the installation (1) comprises means for raising the temperature therein during a period of rest, above the temperature required to kill the bacteria, and means (7, 8) for sending the air free from bacteria.
