The heat loss in the lees dryer during the drying process will affect its drying effect. Today, I will introduce the heat loss treatment method of the lees dryer.
First of all, it should be checked whether there is a problem with the heat source. If the fuel in the hot blast stove does not burn enough, it cannot guarantee that it will provide sufficient heat to the drying equipment. Perform daily cleaning and regular inspection of the hot blast stove to prevent the inlet and ventilation openings from being blocked. In addition, according to the size of the fuel burning value, appropriate additions should be made to maintain the supply of fresh air to improve the fuel burnout rate. Another is the tightness of the equipment: the high-temperature flue gas generated by the heat source is transported to the inside of the drying equipment through the hot air pipe. If there is a leak in the transport pipe, heat will be lost and wasted during the transportation. Finally, the insulation of the dryer barrel: the insulation performance of the barrel material and the impact of the external environment will weaken the insulation function of the lees drying equipment, so that a large amount of heat will be lost through the barrel, which will affect the drying effect and quality of the material.
Zhengzhou Dingli's distiller's grain dryer is made of high-quality raw materials and precision-machined. It has good thermal insulation and tightness. It also provides customers with technical support and services. Customers who need it can come to the factory to buy it.
