Product Descriptions
◆ “XianDao” spray dryer has enjoyed unique success ever since it was first introduced to our customers. more than 200units have been supplied to universities, research centers, and specialist Powder Production facilities around the world.
◆ It has been introduced to meet the increasing demand of a more flexible, reliable, modern and user friendly laboratory dryer having different levels of control systems.
◆ Spray drying is a unique drying process involving both particle formation and drying. The powder characteristics can be controlled and powder properties maintained. Constant throughout a continuous operation. The selection and operation of the atomizer is of extreme importance in achieving an optimum.

1,located in the centre of the chamber roof．An air turbine drive operating from a 6 bar compressed air source， supplies power to the；atomizer wheel．A vaned atomizer wheel is used fornon-abrasive feeds and an atomizer wheel with carbide bushings for atomizing abrasive feeds．Particles in the range 5-25μm are created.

2,located also in the centre of the chamber roof..The atomization is created by compressed air at a pressureof 0.5-2.0 bar£®The feed and atomizing gas are passed separately to the nozzle head where the atomization takes place£® Two-fluid nozzles have the advantage of handling more viscous feeds£®Theco-current mode is selected for drying heat-sensitive products to fine particles in the range 5-25μm

3,Located in the cone of the drying chamber, spraying upwards．The fountain mode is selected to meet a more coarse and free-flowing powder specification． Often used for fine ceramics and other non-heat-sensitive products．The counter- current flow offers a dryer performance with excellent heat utilization and provides the longer powder residence time in the drying chamber required to complete the drying to larger particles in the range 15-80μm.
