Direct cooling and packaging of finely-divided powders, especially pigments or cement, involves cooling with a gas followed by bulk packaging, especially in paper or plastics sacks

Direct cooling of solids of average particle size below 50 (especially below 20) mu by addition of a cooling medium, followed by filling into bulk packaging, uses either one or more different low-boiling condensing gases (I) or a cold gas (mixture) obtained using (I) or a cold gas (mixture) pre-cool...

Beschreibung
Zusammenfassung:	Direct cooling of solids of average particle size below 50 (especially below 20) mu by addition of a cooling medium, followed by filling into bulk packaging, uses either one or more different low-boiling condensing gases (I) or a cold gas (mixture) obtained using (I) or a cold gas (mixture) pre-cooled by other means. An Independent claim is also included for apparatus for cooling finely-divided solid powders consisting of: (a) a storage container for low-boiling condensing gases, (b) an insulated connector between the storage container and a pneumatic powder conveyor, (c) a nozzle for introducing the gas into the conveyor and (d) control and regulation devices. Offenbart wird ein Verfahren zur direkten Kühlung von heißen, feinteiligen, pulverförmigen Feststoffen durch Zugabe eines Kühlmediums in Gestalt von niedrig siedenden, kondensierten Gasen oder kalten Gasen und anschließende Abfüllung der Feststoffe in Schüttgutverpackungen. Offenbart wird außerdem eine Vorrichtung zur direkten Kühlung der feinteiligen, pulverförmigen Feststoffe sowie in Schüttgutverpackungen befindliche feinteilige, pulverförmige Feststoffe mit einem gegenüber Luft geringeren Sauerstoffgehalt in der Gasphase zwischen den Feststoffpartikeln.
