Wood drying method

Abstract

The invention relates to the field of wood storage, and discloses a wood drying method. The method comprises the following steps of a, placing wood into liquid to be stewed, b, burying the stewed wood into high-temperature sand, c, taking out the wood from the sand and placing the wood into a heating furnace to be heated and dried under a vacuum condition, d, taking out the wood from the heating furnace and placing the wood outdoors to be naturally air-dried, and e, immersing the wood into liquid wax to form a wax film on the surface of the wood. Different from an existing drying method, the wood is dried through the high-temperature sand before being heated and dried, water is absorbed more evenly and mildly, and the drying degree in the wood is made more even, so that the fracturing phenomenon on the surface of the wood is effectively prevented, and material waste is avoided.

Description

technical field [0001] The present invention relates to the field of wood preservation. Background technique [0002] Timber generally refers to wooden materials used in industrial and civil buildings, and is often divided into soft wood and hard wood. The wood used in engineering is mainly taken from the trunk of trees. Because wood is easy to obtain and process, it has been an important material since ancient times. of building materials. In the process of removing wood from the tree and using it as a building material, it is inevitable that it needs to be dried. Wood drying is to ensure the quality of wood and wood products and prolong the service life. Appropriate measures must be taken to keep the moisture in the wood (moisture content) is reduced to a certain extent. [0003] At present, there are various methods for wood drying. The more common method is to cook the wood first, dissolve and remove the sap inside the tree, and then dry the wood with hot air. Most of ...

However, with this conventional scheme, when the wood is put into the heating furnace for heating, the hot air first evaporates the moisture on the surface of the wood, while the moisture in the interior of the wood and in the middle of the wood cannot evaporate quickly, which has the following disadvantages: causing dryness Unevenness, when the inside of the wood reaches the drying effect, the surface of the wood is over-dried by hot air, and the surface is prone to cracks, which makes the thicker layer of wood on the surface unusable and wastes materials
