Spray dryer to granulate powder and to dry wet powder
This unit has been designed to
granulate powder and to dry wet
powder using a fluid bed. This is a
fluid bed drying granulator that is
used in the combination of Basic unit
GB210 and Mini-bed attachment
GF200. The unit supports multiple
power supplies of AC200V, AC220V,
and AC240V.
• Experimental conditions such as the
hot air temperature, air amount, binder
liquid sending amount can be set with
the setting dial on the front of the unit
easily.
• The chamber is made of ultra hard
glass and the user can observe status of
the fluid bed or spraying status. Also,
the flowage meter, the spraying
pressure meter, the chamber inlet/outlet
temperature indicator are useful for
evaluation of data.
• The unit can also be used as a spraying dryer by installing the mini spray attachment GF300 (optional).
• The unit also has an automatic lift as a standard to enable convenient attachment or removal of the drying
air flow meter (voltage type) or attachments.
• Product configuration is global as can be seen in the multiple power supplies and the touch panel that
supports Japanese, English, and Chinese.
