(Summary description)We know that wet wood contains a lot of water, and wood products processed from wet wood are prone to deformation and cracking during use, so the wood needs to be dried.

 

Although there are many methods for drying wood, due to the particularity of wood drying, drying wood is often placed in stacks in the furnace, so it is generally difficult to heat evenly and penetrate deep into the pile. Fires may sometimes occur due to excessive local temperatures. The drying method uses infrared radiation heating as the main method and forced convection as the supplement. As long as the drying process is strictly controlled, the dried wood will not crack or warp, the quality is stable and uniform, and the cost is low, the cycle is short, and energy is saved.

 



 

 

The drying process and its control over the drying effect of wood are also closely related to the stacking of timber stacks. The quality of stacking directly affects the drying quality and time, so stacking is a very important link. The loading of timber stacks , bottom, left and right should have good air permeability, especially the upper and lower should have smooth ventilation holes to ensure that the interior of the wood is heated evenly and the water vapor on the surface of the wood is drained away in time.

 

The drying process is divided into several stages: heating, constant temperature and cooling. Since the drying object is oak wood, which is a hard and difficult-to-dry wood that is easily deformed and cracked, the temperature is raised slowly in a stepped manner. The heating steps are controlled at 50°C, 70°C, 80°C, and 90°C respectively. The maximum temperature rise must be controlled. At a constant temperature of 90°C, in order to ensure that all parts are radiated evenly, it is best to use manual control and automatic control alternately. When cooling down, stop the machine, open the exhaust hole, and cool down naturally.

 

Compared with steam drying, infrared drying has the advantages of less investment, short production cycle, high heat utilization rate, good drying quality, and low cost. It can achieve goals of high efficiency and speed, energy saving and stable wood quality. It is believed that in the future development, infrared heating technology will play a greater role in the field of wood drying.



Medium wave quartz infrared heater lamp are particularly suitable for the fast heating of surface or thin materials, and the range of IR radiation wave is 2.2-4.0μm. Plastic, water and other solvents absorb well this medium wave radiation. Because of its long working life and economical efficiency, medium wave infrared quartz heater lamps are popular used in continuous heating processes and long heating machine or drying oven.

 

Twin tube medium wave IR lamp is made of quartz twin tube with sizes of 23×11mm or 33×15mm. The heating filament is Ni-Cr or Fe-Cr alloy material. The total length of twin tube medium wave IR heater can be up to 6 meter. In order to better convey and focus on the heated material all the IR radiation emitted from the IR lamp, the special gold reflector or white reflector will be coated and fixed directly on the quartz surface.

 

                                                 





 

The response time of medium wave infrared quartz emtter is 1-4minutes, the emitters can provide constant and uniform infrared heating when they run stably. We are customized IR radiator lamp manufacturer and we have the following medium wave twin tube infrared lamps for your reference.
