Working Principle:

Hot air wood drying equipment can dry various tree species, specifications, and uses of wood. It has the advantages of high efficiency, energy saving, safety and reliability, short drying cycle, good drying quality, and low drying cost. It is widely used in large, medium, and small wood processing enterprises, especially for manufacturers engaged in wood product export business. The MCM series wood drying equipment, during normal operation, the fuel is fully burned in the combustion chamber, generating heat energy, which is fully absorbed by the drying medium in the heat energy drying system, producing a temperature of about 180 degrees Celsius. Under the action of the circulating fan, the high-temperature airflow is transported to the drying chamber through the control system and conveying system to dry the wood. At the same time, the steam generation device on the equipment can produce a large amount of atmospheric steam. According to the requirements of the drying process, the steam can be timely sent into the drying chamber to spray steam and adjust the humidity of the wood. The humidity control system is an independent steam system equipped with safety devices. Saturated wet steam can quickly make the surface temperature and internal humidity of wood consistent, thereby achieving the goal of drying both the interior and exterior of wood simultaneously. For solid, thick and hard wood, intermittent heating drying technology can be used to solve defects such as internal cracking, end cracking, and deformation that occur during the drying process, greatly improving the yield of high-quality wood products. The wood drying equipment is equipped with a heat recovery system, which significantly reduces the drying cost and shortens the drying cycle. When the moisture content of wood drops below 15%, after 6-8 hours of high-temperature dry steaming, all parasitic insects and their eggs inside the wood can be eliminated, solving the adverse effects caused by insects and improving the economic efficiency of the enterprise.

Main features of the product:
1. It is made using a rotary heating device, consisting of a combustion chamber, a thermal energy conversion chamber, a steam generation device, a combustion supporting device, a fan, a water mist dust collector, a chimney, and other parts. Efficient and energy-saving, with high thermal energy conversion rate.
2. The clean hot air inside the furnace is introduced into the wood drying room through the induced draft fan by the hot air stove. The high-temperature and high humidity resistant axial flow fan in the drying room is used to achieve uniform drying of the wood in each area by the hot air. The hot air in the drying room is heated multiple times through a hot air recovery system to achieve heat recovery and utilization. Thus reducing the cost of use, it is a relatively economical equipment for wood drying and drying in China.
3. The hot air stove separates the combustion chamber from the hot air system, providing pure hot air without any pollution to the wood. Eliminating the risk of igniting materials inside the drying room and causing safety issues such as fires that may occur during traditional wood drying.
4. Dried wood has a short drying cycle, low cost, uniform drying, and good effect, which solves the defects such as internal cracking, fracture, surface cracking, deformation, and discoloration that occur during the wood drying process.
5. The hot air temperature can be adjusted and controlled between 35 ° C and 100 ° C according to the needs of different types of wood, achieving drying of various hardwoods, hardwood, and softwood. This is achieved by controlling the oxygen intake through a butterfly valve.
6. Using wood hot air drying equipment, it can dry to any desired final moisture content without being limited by natural conditions. It has mature drying theory and process technology, which can ensure drying quality. Compared with air drying, it has a shorter drying cycle, higher production efficiency, smaller footprint, less complex equipment, long service life, safety and reliability, and good economic effect.
7. The equipment is made of all aluminum structure, with good thermal conductivity and corrosion resistance, which increases the service life of the equipment. The appearance is beautiful and generous. It can be designed as one furnace with two drying rooms to facilitate rotating operations according to requirements.
8. The fuel required for combustion includes shavings, sawdust, wood scraps, coal, etc., which are widely used. We can also customize electric heating type, coal (diesel) electric dual-use type, steam heating type, thermal oil heating type, etc. according to the needs of users.

Main technical parameters: (for reference only)

Reasonable planning and design can also be carried out according to the actual situation of the user, and design drawings can be provided to customize for the user.

Attention should be paid to the use of hot air wood drying equipment:
1. The wood enters the drying room and during the stacking process, using a reasonable spacing density can accelerate the drying speed of the wood. Reasonable drying technology and moisture removal time can improve the drying effect of the wood.
2. Try to minimize the simultaneous drying of wood with different thicknesses, densities, and moisture levels.
3. Regularly open the cold air inlet, and pay attention to the intake air volume of the cold air outlet when opening both the cold air outlet and the moisture outlet at the same time to avoid excessive temperature difference in the drying room.
4. Drying wood is a matter of haste, so the heating should not be too fast, otherwise wood cracking may occur. It is also important to pay attention to the stacking of wood, ensure even heating, and consider the direction of wind flow to allow hot air to circulate through the stacked wood.
