| 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.
