木材真空干燥设备原理:

将要干燥的木材放在一个密封的容器内,在低于大气压力下进行干燥,加快木材内部水分向木材表面移动速度。在对木材不断加热的过程中,同时利用真空系统消除干燥室内的空气,免受空气影响,干燥室内的汽化温度降低,木材可以在较低温度下进行干燥,从而避免了因温度过高而导致的木材开裂、变形等缺陷。干燥时间通常30mm左右薄板只需24小时,50mm左右板材只需72小时,60-70mm左右板材只需96小时,比常规干燥时间缩短了约5-15倍。

A:绿色干燥

   能集中处理木材因干燥而排出的有害物质。

B:干燥质量稳定

   设备避免了因蒸汽产生的温度梯度差,无弯曲、变形、开裂、表面硬化、材色改变等现象。部分弯曲木料可通过热压干燥调直。

C:干燥耗能低

真空干燥技术可称为节能干燥技术。相对常规干燥设备而言,内部水汽温度降低,干燥周期缩短约5-15倍,对密度大、难干燥木材更显优势。

D:操作灵活

   操作简单、方便、易懂

E:安装方便

   设备占地面积小,安装简单运输方便。

Vacuum Timber Drying Equipment

Mechanism:

In the process of continually heating for the timbers, meantime, make use of the vacuum system to eliminate the dry indoor air, affected by vacuum, the vaporization temperature in drying chamber will become lower, and the timber’ can be dried under lower temperature, this can avoid the splitting and deformation of timber caused by higher temperature. The drying time for about 30mm sheet is 24h, for about 50mm sheet is 72h, for 60-70mm sheet is 96h, which has shortened by about 5-15 times than conventional drying time.

Features:

A: Green Drying

  Wood drying hazardous substances can be disposal centrally by this equipment.

B: Stable Drying Quality

  There is no temperature gradient caused by inner steam, so drying defects, such as bending, deformation, cracking, surface hardening and color changing, can be prevented. Some bending timber can be re-flattened by press drying process.

C: Low Power Consumption 

 Vacuum drying is a process of energy saving. Compare with conventional drying, vacuum drying has lower vapor temperature, and shorter drying period, that is 1/15-1/5 of conventional drying period, especially for timbers with high density and hard to be dried. 

D: Flexible Operation

  It is easy and convenient to operate.

E: Easy Installation 

  The vacuum drying equipment occupies a smaller working area, and easy to be installed and transported.
