<p>In a method for preventing bacterial growth in a refrigerating or freezing plant for food, the plant (1) comprising a substantially closed housing (2) and, arranged therein, means (3) for refrigerating food in this housing, and having an operating cycle which comprises a work period during which the refrigerating means (3) are active, and a rest period during which the refrigerating means (3) are inactive and the plant can be cleaned, the cleaning includes raising the temperature in the plant above a temperature requisite for killing bacteria. Furthermore, the air pressure in the plant is maintained higher than the ambient pressure, at least during the entire rest period, by supplying air free from bacteria. The plant (1) comprises means for raising the temperature therein during a rest period above a temperature requisite for killing bacteria, and means (7, 8) for supplying the air free from bacteria.</p> |
