Drying machine is to rely on heat source to provide heat to make the air inside the dryer cylinder heat of the tube material for drying. In this way, if you want to ensure that the work of the dryer and work efficiency. It is necessary to ensure that the temperature of the hot air, that is, the need to maintain stability of inlet and outlet temperature.



Drying machine for different materials drying temperature is also different, the general drying machine inlet flue gas temperature: 800-600, dryer outlet gas temperature: 80-120. When the outlet and inlet temperature is too low or too high temperature will affect the drying efficiency and the quality of the finished product. The dryer temperature control by furnaceman conditioning monitoring, temperature control.

Decreased gas temperature measures include: cutting furnace blower air volume, less coal, open the door cool breeze, open the cool breeze valve. To improve the temperature of furnace gas can be increased under the air blower: furnace, furnace slag and coal, pass, closed valve to cool. And the amount of coal to adhere to the "eat more meals". In order to get accustomed to many kinds of production, recently a hot air drying machine selected motor stepless speed regulation, according to the formula needs convenience conditioning at the tail part of the temperature difference. If this machine selection frequency conversion motor, temperature by computer control, will be more rapid.

In addition, Dingli company thought dryer temperatures in addition to be monitored by the thermometer and experienced operator can also by looking at the color of finished materials, dry humidity of the concrete operation. So as to ensure dryer temperature balance and stability, so as to guarantee the drying yield.
