by utilising, as heating medium, the saturant vapour of methyl alcohol at atmospheric pressure, and which boils at the temperature above stated, or by employing such other liquid as boils at the particular temperature required. Consequently the invention is applicable to liquids other than milk by selecting, as the heating medium, a liquid the saturant vapour of which at atmospheric pressure corresponds to the temperature it is desired to attain.
