Product  Description

“xian dao” Pilot 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 still increasing demand for a more flexible, reliable, modern and easy -to -handle laboratory dryer having different levels of control systems.

Same time, 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.

 

                                                                                 

 

Rotary atomizer

　　
located in the cent re of the
chamber roof. Atomizer using
high-speed motor drive, 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
5-25um are created.
 

 

Co-current two-fluid nozzle

　　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 5-25um．
 

 

Fountain two fluid nozzle

　　Located in the cone of the drying
chamber,spraying upwards．
The fountain mode is selected
to meet a more coarse and freeflowing
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 15-80um.
