In some of the prior pasteurizers the bottles are tilted slightly while entering or passing out o the pasteurizing fluid, but this movement o the liquid'and fluid is quickly transmitted l'verting or otherwise turning the The ordinarymethod of pasteurizing bot#v tled liquids consists in placing in an endless jcarrier which travels'slowly.
