Timber drying apparatus

The present invention relates to a wood drying apparatus, and more specifically, it is possible to set the humidification and heating conditions according to the type of wood by an automatic drying system, and to dry the wood loaded in the drying chamber uniformly, The present invention relates to a wood drying apparatus capable of preventing deformation of wood and adjusting moisture content of wood.

Generally, the timber harvested from the mountain region contains a large amount of water equivalent to about 80% of the dry weight. When the wood products are manufactured by processing the harvested timber as it is, the moisture contained in the timber is dried. Since the transformation of wood products occurs during the process, the moisture contained in the wood products should be sufficiently dried before making them into furniture or building wood products.

Drying of wood reduces moisture content, reducing transportation costs and storing safely, preventing damage caused by shrinkage of wood, increasing the strength of wood, increasing nail or screw retention, improving adhesion and paintability, and improving electrical insulation. Increasing, improving the thermal insulation, ease of medicinal herb leaf, preventing the damage, discoloration and corruption can be obtained.

As a method of drying the moisture contained in the wood as described above, the natural wood drying method is to leave the felled wood in the same place as the timber factory for a long period of about 3 to 5 years, or Timber or Lumber Rapidly drying method is usually carried out by loading the raw wood processed as a building or furniture timber, such as in the drying room, and then injecting high hot air of 80 ~ 100 ℃ into the drying room within a few days.

The natural drying method has to move the wood frequently for smooth drying of the raw wood, there is a problem that the degradation of the wood due to productivity degradation and pests caused by excessive drying time, the rapid drying method is a hot air to dry the wood Compared to the natural drying method, dry deformation such as warping, twisting, and cracking of wood is more likely to occur, and fossil fuels such as petroleum and coal are used to form hot air required for drying wood as well as drying wood. Once used, there is a problem that causes waste of energy due to almost outside discharge.

The artificial drying method is to dry wood rapidly and without damage by using artificially set drying conditions to a low moisture content which cannot be reached by natural drying. There are a number of devices and methods that can artificially adjust drying conditions, including fume drying, electrothermal drying, combustion gas drying, vacuum drying, chemical drying, and high frequency drying.

The hot-drying method is subdivided according to the method of making the hot air and the circulation method of the hot air and the progress of the drying operation, an embodiment of the wood drying apparatus designed using such a hot-drying method is shown in Figures 7 and 8.

Energy consumption is increased, in particular, heat is easily released, there is a problem that it is difficult to maintain a uniform temperature which is the most important factor of wood drying.

In addition, the drying chamber 400 is not provided with a means for supplying a separate moisture is not possible to control the moisture contained in the wood is a problem that the deformation of the wood is badly generated, and to dry the moisture-containing wood required by the consumer There is a problem that can not be.

In addition, by using a bulky block (B) to apply a top load to the top of the loaded wood to evenly dry the wood to be dried, the amount of wood to be dried can be relatively reduced in one drying. Inevitably inefficient, as the wood (B) is closely packed with each other, air cannot flow smoothly, and the wood is unevenly dried, which causes partial deformation of the wood.

The present invention has been made to solve the above-mentioned problems, an object of the present invention is to set the drying schedule suitable for the target wood by the database of the wood drying schedule to control the wood-containing powder by drying the controlled shoe powder In addition, uniformly compresses and secures the wood loaded in the drying chamber with a high-compression compression band, and also allows air to flow smoothly between the woods, resulting in deformation and cracking of wood due to high temperature heat during drying. It is to provide a wood drying apparatus that can be blocked and dried to a good quality wood.

The configuration of the present invention for achieving the above object, is provided with a heater and a humidifier in the drying chamber inside the main body and a ventilation port for discharging the wet steam generated from the wood is provided on the upper side of the drying chamber, suitable for the target wood In the wood drying apparatus for automatically drying the wood by applying a schedule, the drive shaft 13 is supported by the front portion of the main body 10 is rotated by a wrench 12 and provided with a motive gear 14 on the shaft and; A driven shaft (15) provided on the shaft with a driven gear (16) which is engaged with the driving gear (14) of the driving shaft (13) and shifted in rotation, and is installed in one side of the main body (10) in a transverse direction; A band fixing groove 16a formed at a predetermined interval on the driven shaft 15; A plurality of compression bands 17 fixed to one side of the band fixing groove 16a to surround and compress wood; A plurality of compression band fixing means which are provided in the transverse direction on the other side of the main body 10 and rotated in one direction to fix the other side of the plurality of compression bands 17; A sticker 40 inserted between the wood loaded in the drying chamber 11 to support the wood and inducing a smooth air circulation; It is characterized by consisting of a door 20 supported by the cylinder 21 to open and close both sides of the main body 10.
