Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wood-

TECHNICAL FIELD The present invention relates to an apparatus for efficiently performing an insecticidal heat treatment on wood which has suffered from various pest insects such as reeduces.

In general, timber is a material that can be produced continuously, and has become a very popular material nowadays because of its growing interest in the global environment.

However, as timber is derived from living organisms, there are many variables in timber production. For example, changes in species can occur through climate change. In particular, it is possible to damage the pests and diseases that have recently become polarized in our country. .

These pests and diseases have been increasing steadily, and the Korean Forest Service has tried to suppress the propagation of insect pests by controlling them, but it is not getting smaller.

Currently, most of the affected trees are left in the mountain after being treated with fumigation and wait until they are rotten, or they are left on the roadside by covering the fumigated damage with vinyl.

However, in the case of fumigation, it is not only costly but also it is difficult to eradicate the larvae completely, and damage is spreading due to infections and vinyl tears caused by unauthorized movement of the damaged tree.

Therefore, studies on the utilization of such damaged wood as a resource that can be used for industrial purposes are now being actively pursued.

As an example, Korean Patent Registration No. 10-1547469 discloses a " device for re-infecting wood-based disinfection apparatus " in which wood is dry-sterilized to recycle wood infected with the re-infestation.

The apparatus for sterilization of the wood-blown infective wood-based disinfecting apparatus according to the present invention comprises a container for carrying a recycled infectious neck, a heating chamber installed on the bottom of the container for maintaining the heat inside the container, And a burner.

However, the above-mentioned " device for dry-sterilizing infective wood of the re-infected worms " means that the wood is not uniformly heated as a whole because the wood burns the flame directly at the lower part of the heating chamber in which the layer is piled up. But the larvae remain in the deep part of the wood. In addition, the efficiency of sterilization of the pest and disease is low, and the operation time is long and the energy consumption is large.

When the temperature in the heating chamber is set to a high temperature for the complete sterilization of insect pests and diseases, the wood on the lower side is completely carbonized, and the physical properties of the wood on the upper side are also reduced.
