Quatorze séchoirs à convection pour la production continue
La gamme de séchoirs à convection SINOTHERMO couvre le séchage par pulvérisation centrifuge et sous pression, le séchage sur plateaux et sur bande à air chaud, le séchage flash par spin-flash et pneumatique, le séchage en lit fluidisé horizontal et vertical, le traitement en four rotatif, ainsi que le séchage sur lit vibrant — tous conçus sur le principe du contact direct avec l'air chaud pour un fonctionnement continu à haut débit.
Choisir un séchoir à convection selon le type de produit à traiter
Les produits liquides sont atomisés par les séchoirs par pulvérisation (LPG, YPG, GXP, ZLPG) en une fine poudre sèche. Les gâteaux humides et les pâtes passent par les séchoirs flash (XSG, Pneumatique) pour une élimination de l'humidité en quelques secondes. Les solides granulaires et pulvérulents sont fluidisés dans les séchoirs à lit fluidisé (FG, XF, GFG, ZLG) pour un séchage continu et uniforme. Les solides en vrac traversent les séchoirs à bande (DW), à plateaux (CT-C), à four rotatif (HZG) ou vibrants (LZG) selon le débit et le temps de séjour requis.
