Fine powder pharmaceutical dryers are better than flash dryer.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
Fine powder pharmaceutical dryers characteristics
The drying speed is high when the material liquid is atomized , the surface area of the material will increase greatly .In the hot-air flow,95%-98% of water can be evaporated within only seconds.More suitable for drying the heat sensitive materials.
Spray Dryer final products own the advantages of good uniformity, flow ability & solubility. Also high in purity and good in quality.Amylase dryer the production procedures are simple and the operation and control are easy .The liquid with moisture contents of 40-60% (for special materials, the contents might be up to 90 %.) can be dried into the powder or particle products once a time. After the drying process, there is no need for smashing and sorting, so as to reduce the operation procedures in the production and to enhance the product purity .The product particle diameters, looseness and water contents can be adjusted through changing the operation condition within a certain range. It is very convenient.
