The distiller's grain dryer relies on the heat source to provide heat to make the air in the dryer barrel heat up to dry the materials in the barrel. In this drying method, if you want to ensure the working effect and efficiency of the dryer, you need to ensure the temperature of the hot air, that is, the temperature of the inlet and outlet needs to be kept stable. The drying temperature of the dryer is different for different materials. Generally, the temperature of the flue gas at the inlet of the dryer: 600-800℃, and the temperature of the exhaust gas at the outlet of the dryer: 80-120℃. Excessively low or high outlet and inlet temperatures will affect the drying efficiency and the quality of the finished product. The temperature control of the dryer is generally monitored and adjusted by the furnace worker against the thermometer.

  How to ensure the stability of the temperature of the vinasse dryer:

  1. Maintain an appropriate temperature: Because the drying temperature of different material types and humidity is also different, according to different material types and material humidity, the general dryer feed temperature dryer inlet flue gas temperature: 600 ~ 800 ℃, dryer Outlet exhaust gas temperature: 80～120℃.

  2. Do not increase the temperature arbitrarily: Sometimes the temperature inside the cylinder is relatively low because the raw materials are put in too fast. At this time, do not increase the temperature of the hot blast stove at will, adjust the feeding amount according to the moisture of the discharged material after drying, or open the damper of the induced draft fan to prevent the material inside the cylinder from catching fire. In addition, if the moisture of the discharged material is too large and the drying is insufficient, do not adjust the temperature at this time, and open the damper of the large induced draft fan to make the raw materials more fully contact.

  3. The outlet temperature is well controlled: if the outlet temperature of the dryer is too low (below about 55℃), condensation and condensation will occur, causing the condensation inside the electrostatic precipitator to produce "discharge and creepage" phenomena, reducing the dust removal effect and corrosion the internal electrode plates and filaments of the electrostatic precipitator cause the vibration of the fan impeller and aggravate the damage of the fan. Therefore, when we use the dryer, we must control the outlet temperature of the dryer at an appropriate temperature to achieve the ideal drying effect.

  How to reduce and increase the temperature of the gas in the distiller's lees dryer during the daily operation?

  Ways to lower the temperature of the furnace gas are: reduce the air volume of the blower under the furnace, add less coal, open the furnace door to introduce cool breeze, and open the cool breeze valve. Ways to increase the temperature of the furnace gas are: increase the air volume of the blower under the furnace, pass the furnace to discharge slag, add coal, and close the cool air valve. The amount of coal added must adhere to "eat less and more meals." In order to get used to various types of production, a hot air blower in front of the dryer recently uses a stepless speed regulation motor, which can conveniently adjust the temperature difference between the head and the tail according to the recipe requirements. If this fan uses a variable-frequency speed-regulating motor and the temperature is controlled by a computer, it will be faster.
