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.

Abstract: The invention relates to a static mixer for continuous mixing of one or more input streams or flows. The mixer comprising a pipe section of a certain length, the pipe length being pinched together so that a number of radial throttles is formed. The throttles are uniformly distributed along the pipe section. Two adjacent throttles are moreover oriented at 90° in relation to one another.

Abstract: The present invention relates to a method and an apparatus for mixing two flows, a first, larger flow (2) and a second, smaller flow (3). The apparatus includes a T-pipe (4) where an inlet (5) for the first flow (2) and an inlet (6) for the second flow (3) are placed at 180° in relation to each other. The second flow (3) is thereby introduced into the first flow (2) in a direction which is opposed to that of the first flow (2). The T-pipe (4) also displays an outlet (7) for the mixed flows (8). The outlet (7) is placed at 90° in relation to the two inlets (5, 6). The two flows (2, 3) are thereby forced to change direction immediately after the mixing.
