Peddeldroger technologie

• Groot thermisch oppervlak:– Peddels

– Assen

– Trog

• Compleet gesloten configuratie

• Geschikt voor vacuum

• Thermisch medium: stoom, olie of water

• Mechanische overloop t.b.v. produktniveau

• Produktcontactdelen: toepassingsspecifiek (RVS)

12-13 June 2008

Peddeldroger technologie II

•

• Peddels loodrecht op draairichting

• Continue produktdruk op beide zijden van de peddel

• Goede radiale menging

• Prop-stroom in axiale richting

• Produkttransport door gravitatie en “fluïdisatie”

• Zelf reinigend effect door “in elkaar grijpende peddels”

• Minimale produktbeschadiging bij fragiele produkten
