(6) Temperature control system
Drying tunnel uses digital temperature controller to adjust the temperature automatically, it can display and control the drying tunnel temperature in real-time.
The temperature measurement uses platinum resistor temperature sensor.
The drying tunnel temperature can be adjusted continuously from normal temperature to 200°C.
3.3. Exhaust pipe
The entrance/exit of the drying tunnel on the top equips with exhaust pipe and butterfly valve, it is used for draining the
exhaust gas of the drying tunnel.
The material of the exhaust pipe is δ1mm galvanized sheet.
