Abstract

759,990. Sterilizing liquids. ALPURA AKT.-GES. Nov. 9, 1954 [Nov. 11, 1953], No. 32447/54. Class 49. Liquid is sterilized by conducting it through a passage 1, Fig. 1, having a constriction of the flow cross-section of the venturi type, constituted by two wall parts 4, 5, and heat applied by introducing steam into the liquid through inlets 16 in the wall of the passage in the region of maximum flow velocity of the liquid. The relative dimensions of the passage and constriction are preferably such that the flow velocity in the region of the steam inlets is at least ten times that immediately upstream of the convergent section. In the region of the steam inlets the passage may have two opposite approximately parallel flat sides 18, 19, Fig. 2, in which the steam inlets are disposed ; the distance between the other sides 20, 21 may be varied according to the rate of treatment. The transition edges between the rectangular and circular sections of the passage are indicated at 24. The steam is supplied through entry pipe 8a and chamber 9 and grooves 14, 15, Fig. 1, may be formed in the outer surfaces of the passage walls 4, 5 upstream from the point of introduction, the thickness of the walls being several times the length of the steam inlets ; the inlets are preferably inclined in the direction of liquid flow, as shown. Additional steam inlets may be disposed in a diffuser section, as shown in Fig. 4. All parts except packing are preferably of corrosion-resistant steel. The method is stated to be especially suitable for sterilizing milk, milk-containing liquids and fruit juices. Specification 731,894 is referred to.
