What are the characteristics of dryer boxes

The dryer boxhave high processing capacity, low fuel consumption, and low drying costs.

The dryer has the characteristic of high temperature resistance and can use high-temperature hot air to quickly dry materials. Strong scalability, design takes into account production surplus, and even if the output increases slightly, there is no need to replace equipment. The equipment adopts a self-aligning tugboat structure, which greatly reduces wear and power consumption due to the good coordination between the tugboat and the roller. The specially designed blocking wheel structure greatly reduces the horizontal thrust caused by equipment tilting operation. Strong overload resistance, stable simplified operation, and high reliability.

Technical principle of box dryer

• hot air circulating system
• By driving hot air through a fan to circulate inside the box, using thermal oil, steam, hot water, or hot air as heat sources, forced convection is used to reduce the moisture content of wood.
• Accurate control of humidity and temperature
• Humidity regulation: Equipped with an independent steam system, it quickly balances the humidity inside and outside the wood through a steam spraying device to prevent cracking and deformation. For example, in the early stage of drying, a large amount of steam enters the room, and the humidity can reach over 80%, ensuring that the surface and core of the wood are dried synchronously
• Temperature control: The working temperature range is 35 ℃ -180 ℃, using a PID intelligent controller with a temperature fluctuation range of ± 1.5 ℃, adapted to the needs of different tree species (such as pine drying cycle of 3-7 days, hardwood requiring intermittent heating process)
• Stress relief technology
• In response to the tensile/compressive stress during the drying process of wood, the drying stress model is controlled within a safe range through gradient heating (heating at 5-10 ℃ per hour) and equilibrium treatment (constant temperature and humidity stage lasting 6-12 hours), resulting in a 20% -30% increase in high-quality wood yield.

Scope of use of inovate dryer box

Widely used for drying logs, such as cedar, poplar, elm, pine, cypress, eucalyptus, oak, redwood, nanmu, bamboo, wooden boards, wooden pallets, wood block particles, etc.

• Furniture manufacturing industry: Hardwood drying. For high-density woods such as rosewood and oak, intermittent heating technology is adopted (such as heating for 12 hours a day and stopping for 12 hours) to solve the problems of internal cracking and end cracking. The moisture content of the finished product is controlled at 8% -12%, which meets the standards for furniture materials.
• Building Materials Industry: Pine and fir wood are dried using high-temperature rapid drying (180 ℃ hot air circulation) to reduce the moisture content from 30% to 15% in just 48 hours, meeting the strength requirements for engineering materials (static bending strength ≥ 40MPa)
• Craft processing: precious wood protection, good uniformity of the internal environment of container equipment, small temperature fluctuations, avoiding oxidation and discoloration, suitable for drying precious woods such as rosewood and huanghuali, increasing the value of finished products by 30% -50%.

Case study plan for using industrial box dryer

box dryer, also known as industrial European pine board drying machine/particle fired wood drying room/Zhengzhou Fude Machinery, continuously learns, innovates and explores in the wood drying industry. By continuously understanding the problems and practical experience encountered by users in the material drying process, we have established our own planning and solution system, customized design solutions suitable for each user with different material drying needs, and achieved significant results in drying processing technology, which has been recognized by domestic and foreign users.

The working principle of a vented dryer box

Special hot air (steam) drying equipment for wood. During normal operation, the fuel is fully burned in the combustion chamber, generating heat energy.

It is fully absorbed by the drying medium in the thermal 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 room 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 room, and the wood can be sprayed and steamed, and the external conditioning and humidity control system is an independent steam system equipped with safety devices.

Saturated wet vapor can quickly bring the surface temperature and internal humidity of wood to a consistent level, thereby achieving simultaneous drying of both the interior and exterior of the wood. For solid and heavy hard and thick wood, intermittent heating and drying technology can be used to solve defects such as internal cracking and deformation that occur during the drying process, greatly improving the yield of high-quality wood. The wood drying equipment is equipped with a heat recovery system, greatly reducing drying costs and shortening drying cycles.

Customizing larger models of the dryer box according to customer requirements

Multi heat source compatibility: supports various fuels such as sawdust, coal, natural gas, and electric heating, adapts to different energy structures in different regions, and reduces operating costs by 20% -25%.

Why choose a wood dryer

Improving wood quality: reducing moisture content, preventing deformation and cracking: During natural drying of wood, uneven drying speed due to factors such as environmental humidity and temperature can easily lead to uneven internal stress, resulting in deformation, cracking, and other problems. The wood dryer can achieve uniform drying of wood by precisely controlling the temperature, humidity, and airflow speed during the drying process, effectively reducing moisture content, minimizing deformation and cracking, and improving the dimensional stability of wood.

Improving the color and texture of wood: Proper drying treatment can make the color of wood more uniform, the texture clearer, enhance the appearance quality of wood, and increase its market value. For example, some high-end furniture materials can exhibit more beautiful colors and textures after drying treatment, meeting consumers’ demand for high-quality furniture.

Suitable for various types of wood: Different types of wood have different physical and chemical properties, and also have different requirements for drying processes. The wood dryer can adjust the drying parameters according to the characteristics of different woods to meet the drying needs of various woods. Both hardwood and cork, solid wood and artificial board can be dried using a wood dryer.

Adapt to different specifications and shapes of wood: The wood dryer can process wood of different specifications and shapes, such as planks, square logs, round logs, etc. Through reasonable loading methods and drying processes, it is possible to ensure that wood of various specifications and shapes can be uniformly dried, improving the drying quality of wood.
