METHOD FOR COOLING DISPERSION AND LIQUID

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 com...

Zusammenfassung:	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.
