Abstract
1,101,868. Evaporators wherein liquid flows through channels formed by nested heatconducting frustated cones. ALFA - LAVAL AKTIEBOLAG. 12, July, 1966 [12 July, 1965], No. 31165/66. Heading BIB. In an evaporator, suitable for the concentration of milk and juices, comprising a series of heat-conducting truncated cones 1, 2 nested together one within the other in spaced relationship to define alternate channels for the flow of liquid to be evaporated (channels 11) and for the heating medium (channels 10) respectively, wherein the liquid and the heating medium are introduced into their respective channels at the larger periphery, and the boiling liquid and vapour is discharged from the liquid channels at the smaller periphery, and the heating medium is introduced into the channels 10 at their larger periphery, the apex angle or shape of the cones is such that the distance between them in the liquid channels 11 increases from the larger periphery to the smaller in order to accommodate the formation of vapour and to provide decreasing heating surface in the direction of flow of liquid. As shown, alternate cones are of different apex angle, but the increase in cross-section of the liquid channels may also be achieved by employing step-shaped truncated cones. The cones are assembled in housing 13 by means of spacers between the flanges on the peripheries of the truncated cones. The heating medium, e.g. steam, is introduced into the housing through inlet 18, and passes through openings (not shown) between spacers 7 into channels 10, which are closed at the top. The steam condensate flows down channels 10, and is withdrawn from the housing through outlet 19. The liquid to be evaporated is supplied through conduit 20, and flows up through a channel 21 formed by a boring through the housing, the spacers and the flanges of the cones. From channel 21, the liquid flows through radial passages 22 in spacers to liquid channels 11. The mixture of concentrated liquid and vapour is discharged from the upper ends of channels 11 into chamber 24, where the vapour separates from the liquid. The vapour leaves the housing through outlet 25; and the concentrated liquid is withdrawn through outlet 26. Non-condensible gases are removed from channels 10 via tubes 28, channel 29 and conduit 30.
