Fine powder universal dryers introduction

At a high speed of Centrifugal atomizer spray dryer, after the spraying of the material liquid, the surface area of the material will be increased greatly. In the hot-air flow, 95%~98% of water can be evaporated at a moment. The time of completing the drying needs only several seconds.This is especially suitable for drying the heat sensitive materials.

Fine powder universal dryers Application

Fine powder universal dryers have been used to dry products in many industries including food, chemical, mineral and polymer. A broad range of feed materials including powders, cakes, granules, flakes, pastes, gels, and slurries can be processed. For slurries, pastes, or sticky materials, back mixing of the wet feed with a portion of dry product to produce a suitable conditioned material is required. This technology can also be used for cooling applications.

• Agrochemicals

• Ceramics

• Food and feed products

• Inorganic chemicals

• Organic chemicals

• Pharmaceuticals

• Pigments and dyestuffs

Fine powder universal dryers characteristics

The rotor at the conical base of the drying chamber fluidizes product particles in a drying-efficient hot air flow pattern in which any wet lumps are rapidly disintegrated. Using the heat from the airstream, the material dries as it is conveyed. Product is separated using cyclones, and/or bag filters. Typically, cyclones are followed by scrubbers or bag filters for final cleaning of the exhaust gases to meet current emission requirements.

Airborne, fine particles pass through a classifier at the top of the drying chamber, while larger particles remain in the air flow for further drying and powdering.
