Abstract

1,233,196. Sterilizing liquids. A.P.V. CO. Ltd. 12 Sept., 1969 [14 Oct., 1968], No. 48580/68. Heading A2D. In the heat pretreatment of liquids, particularly milk, the liquid is passed to a condenser where it is heated by contact with vapour which has been recirculated from a flash vessel, the treated liquid is then pumped to a steam injector for further heating, and then passed through a restriction to flash vessel which is maintained at a lower pressure whereby vapour is flashed off to the condensing vessel, the cooled liquid being pumped away for further treatment. A suitable apparatus may comprise a condenser in communication with a flash vessel, a steam injector, pump and restriction (Fig. 1, not shown). Alternatively the condensing vessel may be located in the flash vessel. This alternative is shown in Fig. 2 wherein liquid from a heat exchanger is sprayed into an inner chamber 15 which is filled with vapour. The heated liquid is extracted by means of a pump 8, passed through a steam injector and restriction and into the flash chamber 16 via inlet 16a. Vapour generated in this vessel passes through a number of holes 17 into the inner vessel for contact with feed liquid. Cooled feed liquid is removed from the outer vessel by pumping and may then be subjected to evaporation.
