ABSTRACT:
The present invention relates to a method for maintaining aseptic conditions in a juice plant in brief productional stoppages. The plant is of the type where juice concentrate is heated to a certain temperature in that steam is supplied to the concentrate. The juice concentrate is kept at this temperature in a holding tube during a certain interval of time. The juice concentrate is thereafter diluted with water to the correct dilution degree. In brief production stoppages, the supply of juice concentrate, steam and water is shut off. The pressure in the plant is maintained in that a stop valve closes and that steam is supplied in a small quantity through a by-pass conduit placed on the steam conduit. The stop valve is placed downstream of the supply of water. The holding tube which is insulated and connected to a heating loop maintains the temperature of the product in the holding tube.
