METHOD FOR PREVENTING BACTERIAL GROWTH IN A FOOD PROCESSING PLANT AND SUCH A PLANT FOR CARRYING OUT THE METHOD

摘要

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