Abstract

1403140 Sterilization ALFA LAVAL AB 20 Sept 1973 [13 Oct 1972] 44263/73 Heading A2D [Also in Division B2] A method of sterilizing a liquid such as milk or blood comprises directing into contact through an ejection nozzle concentric annular jets of steam and liquid to form a single annular jet, wherein two concentric streams of cold liquid are directed along the inner and outer surfaces of the single annular jet thereby to prevent material from the heated liquid adhering to the surfaces of the nozzle. The cold liquid in the two streams may be the same as the liquid to be sterilized. The method may be carried out using an ejector nozzle which comprises four concentric annular channels for supplying liquid, steam and cold liquid and which open into an annular region surrounding a central plug, the radially innermost and outermost channels being connected in use to a source of cold liquid. The method may be carried out in the ejection nozzle shown in the accompanying Figure wherein the liquid to be treated and steam are supplied through inlets 16 and 17 respectively. The liquid and steam flow through cavities 19, 20 and channels 21, 22 and meet in the zone 23 around plug point 14, the liquid being immediately heated to a sterilization temperature. A portion of cold liquid supplied through inlet 16 flows via holes 24 into slot 15 and then to plug point 14. A further flow of cold liquid enters the nozzle via inlet 7 and flows through channel 6. These flows of cold liquid prevent precipitated material from adhering to surfaces of the nozzle. In an alternative embodiment wherein the holes 24 are not present or have been blocked, cold liquid may be supplied to the nozzle via channel 29 and branches 30.
