Abstract: A method for cooling dispersions or liquids (D/L) after a deodorising process comprising (a) passing steam through the D/L in a boiler (1), causing it to foam, (b) taking the foam from the top of the boiler into an evacuated separator (4) through a jet (5) and thus breaking the foam, (c) condensing the water vapour from the foam in a heat exchanger (8) and removing organic volatiles, and (d) returning the broken foam to (1). This process is continued until the D/L is deodorised to the required extent, then the hot D/L is cooled by transferring it from the bottom of (1) to the evacuated separator (4) via jet (5), the water vapour produced is condensed in (8) as before, and the cooled D/L is taken off at the bottom of (4).
