<p>Apparatus for mixing together milk, a fluoride solution and a flavouring solution to produce a pleasant-tasting fluoridated beverage, comprises two sets each of three vessels (10, 11, 12) for containing the respective liquids to be mixed. The volumes of the three vessels are in the proportions in which the liquids areto be mixed and inletflows from supply tanks of the three liquids are metered to fill the three vessels simultaneously. A common inlet valve (13) shuts off the three supplies simultaneously and operation of the inlet valve automatically opens the outlet (16) and mixing valve. As one set of vessels (10) is filled, the other (10') is emptied to provide a substantially continuous flow of the beverage.</p> |
