Auxiliary electric power (kW): 0.18 (1 Phase)
C) Cofi Ignitions: Primary: 230V, 1.5A
Ignition transformer: Secondary, 8KV, 30mA, ignition, 11KV
2.2. Oil burning oven
A) Burner oven air blower (kw): 5.5
B) Oven diameter (mm): 1, 100
C) Oven Length (mm): 2, 200
2.3. Wood flour feeder
A) Auger motor (kw) with speed inverter: 1.5 (reducing ratio: 1: 29)
2.4. Drying chamber
A) Drying chamber diameter (mm): 600 ~ 720
B) Drying chamber length (mm): 3, 900 ~ 4, 500
C) Airflow rate (meter/sec. ): 3 to 5
D) There is a regulating ring near the top of the chamber, which can adjust the flow rate of the air and wood flour. For example, to install a smaller hole ring, the flow rate will be re
The blender blades are at the bottom of the drying chamber, which will generate the turbulent mixture flow inside the chamber to result in heat exchange between hot air and the wet wood flour.
2.5. Airflow duct
2.6. Cyclone separator
A) To separate dried wood flour and exhaust air.
B) An air shutter valve is installed at the bottom of the cyclone
C) Air shutter motor (kw): 1.5
D) There is a small vibrator at the middle of the cyclone to vibrate off any potential hang-up of wood flour inside.
2.7. Dust collector and filter
A) The dust collector chamber has a diameter of 1400 mm, height of 4500 mm. At the top of the chamber, there is impulse filter mechanism to blow impulsed air at the filters to prevent clogging of the filter.
2.8. Wind Shutter
2.9. Exhaust Blower
A) Blow motor (kw): 18.5
2.
On the panel there are the switches of all the motors, oil burner switches, three temperature controllers, feeding speed adjustment, etc.
2.11. Safety control One (1)
Advanced safety and fire monitoring and control device is equipped. In case of fire, the device will automatically shut down the system and spray water on the system.
2.12. Staircase to access vibrator on the cyclone separator One (1)
