MANUFACTURING PROCESS OF DYESTUFF POWERS

A manufacturing process for dyestuff powders is conducted by spray-drying dispersion or solution dyes in a spraydryer where the temperatures of inlet and outlet are 110-260oC and 60-80oC, respectively, and the hot air velocity is 5-80m/sec. The spray dryer consists of (a) an inlet introducing the ho...

Zusammenfassung:	A manufacturing process for dyestuff powders is conducted by spray-drying dispersion or solution dyes in a spraydryer where the temperatures of inlet and outlet are 110-260oC and 60-80oC, respectively, and the hot air velocity is 5-80m/sec. The spray dryer consists of (a) an inlet introducing the hot air into the inside, (b) an outlet discharging powdered dyes and the hot air, (c) an atomizer located at the upper position, and (d) a main dryer body designed to increase the hot air velocity.
