1. Using the drying agent is a mixture of smoke, dust and hot air from the furnace, so it directly affects the quality of the dried product, affecting the working environment.
2. Cost and wastage of combustible materials due to the heat source only take a small part in the furnace through the hot air tube into the exhaust fan, further maintaining the heat supply to the drying system by scratching Ashes, rakes frequently lead to dependence of operators, operational processes, complex fire, unstable, hard working conditions, unsafe, low fire performance of hulls. Scoop up the ash out (waste about 30 - 40% unburned exhaust)
3. Dust smoke is introduced into the drying chamber adhering to the bottom of the drying chamber to reduce the drying capacity, erosion of the bottom of the drying chamber and to regularly clean the bottom of the drying chamber, increase the operating costs and reduce the life of the drying equipment.
4. The life of the furnace depends on the quality of the refractory bricks and the heat-resistant concrete. Continuous firing with high temperatures causes cracking and burning of the furnace.
5. Using the direct source of heat from the furnace, the location of the furnace must be in line with the drying system, which increases the risk of fire, dust and ash from the furnace, affecting the health of the worker.
