Vierzehn Konvektionstrockner für die kontinuierliche Produktion
Das Konvektionsprogramm von SINOTHERMO umfasst Zentrifugal- und Drucksprühtrocknung, Heißluft-Horden- und Bandtrocknung, Spin-Flash- und pneumatische Flashtrocknung, horizontale und vertikale Wirbelschichttrocknung, Drehrohrofenverarbeitung sowie Vibrationsbetttrocknung — alle basierend auf direktem Heißluftkontakt für einen kontinuierlichen Betrieb mit hohem Durchsatz.
Auswahl eines Konvektionstrockners nach Materialtyp
Flüssige Ausgangsstoffe werden in Sprühtrocknern (LPG, YPG, GXP, ZLPG) zu feinem, trockenem Pulver zerstäubt. Feuchte Filterkuchen und Pasten durchlaufen Flash-Trockner (XSG, Pneumatisch) zur Feuchtigkeitsentfernung innerhalb von Sekunden. Körnige und pulverförmige Feststoffe werden in Wirbelschichttrocknern (FG, XF, GFG, ZLG) für eine gleichmäßige, kontinuierliche Trocknung fluidisiert. Schüttgüter durchlaufen je nach benötigtem Durchsatz und Verweilzeit Band- (DW), Horden- (CT-C), Drehrohrofen- (HZG) oder Vibrationstrockner (LZG).
