A kind of fast drying method for wood

Abstract

The invention discloses a novel quick wood drying method. The method comprises the steps in a sequence of: 1) sawing wood into plates with required length and thickness; 2) accurately stacking the wood; 3) packing the wood pile with an iron coat, and then feeding into a kiln; 4) mounting temperature sensors to the centers of the incoming and outgoing piles and the wood; 5) closing a door of the drying kiln to pre-treat the wood; 6) cooling and moving out of the kiln; 7) drying the pre-treated wood by a general manner until the moisture of the wood is qualified. According to the method, the wood is pre-treated under a high-temperature and high-humidity condition; the wood can be sectioned according to the thickness and dried at a plurality of times; the method is suitably used for drying wood of various thickness; the method has the advantages of being high in drying quality, small in drying cycle, simple in design, and small in energy consumption.

Description

technical field [0001] The invention relates to a wood treatment method, in particular to a wood rapid drying method. Background technique [0002] Wood drying is one of the important links in the process of wood product processing. Improving the drying rate and shortening the drying cycle are important ways to reduce drying costs and save energy. In the traditional wood drying process, in order to avoid drying defects during the drying process, when the moisture content of the wood is high, generally a lower temperature is used for drying treatment. As the moisture content decreases, the drying temperature gradually increases, making the whole The temperature during drying is lower. For wood drying, the temperature directly determines the speed of the drying rate, the higher the drying temperature, the faster the drying rate, and vice versa, the slower drying rate. In order to improve the drying rate and reduce the drying cost, the Chinese patent with the publication numb...
