What is the basic structure and main working principle of a drying kiln?
Drying kiln is a large-scale drying equipment used in industrial production, which is widely used in cement industry, metallurgical industry, wood drying, brick and tile drying, and other production processes. During the production process of a drying kiln, the reaction temperature of the kiln body is relatively high. Therefore, the collection and monitoring control of process parameters such as kiln body temperature are important links to ensure the quality of roasting.
Basic structure:
The drying kiln mainly consists of the main body of the drying furnace, drying room, hot air and steam conveying pipeline, recovery pipeline, gate valve, and temperature and humidity instrument. The main body of RHM drying furnace is composed of furnace door and furnace, heat exchange system, steam generation device, combustion support device, ash cleaning port, fan, chimney, and other parts.

Working principle:
The wood specific hot air steam drying furnace drying system mainly consists of the main body of the drying furnace, drying room, hot air steam conveying pipeline, recovery pipeline, gate valve, and temperature and humidity instrument. The main body of the drying furnace is composed of furnace door and furnace, heat exchange system, steam generation device, combustion support device, ash cleaning port, fan, chimney, and other parts.
Characteristics of drying kilns:
1. Low energy consumption, high thermal efficiency, and low power consumption;
2. Low investment, using wood processing residues as fuel, low drying cost, only one-third of steam drying cost;
3. Convenient humidity adjustment, good heat and humidity treatment effect, uniform airflow circulation, and good wood drying quality;
4. Easy to operate and maintain;
5. Compact structure, light weight, movable, independent and modular, easy to install and debug.
