Abstract: PROBLEM TO BE SOLVED: To shorten cooling time of a dispersion or a liq. after deodorizing treatment, to prevent a film which brings adhesion, piling and/or clogging of an apparatus during cooling treatment from being formed in case of a polymer- contg. dispersion and to simplify simultaneously a complicated structure of the apparatus. SOLUTION: Steam is passed through a dispersion or a liq. to be cooled and held in a treating container 1 and the dispersion or the liq. is whipped as the result (a) and this air bubble is discharged from the top part of the treating container 1 and it is fed into a vacuum separating container 4 through a nozzle and the air bubble is exploded during it (b) and steam formed from the air bubble is condensed by means of a heat exchanger 3 and volatile org. components are simultaneously removed (c) and exploded air bubble is returned to the container (d) and the processes (a) to (d) are performed until the dispersion or the liq. is deodorized to a required extent.

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).
