Drying technology for timber

Abstract

The invention discloses a drying technology for floor timber, and belongs to the technical field of timber processing. The drying technology specifically comprises the steps of (1) processing a floor, (2) carrying out primary drying treatment on the floor, (3) carrying out secondary drying treatment on the floor, (4) carrying out third-stage drying treatment on the floor, (5) carrying out fourth-stage drying treatment on the floor, and (6) carrying out drying post-treatment on the floor. The drying technology has the advantages that the phenomena that the floor timber get deformed, cracked and bent in the drying process can be well prevented, the drying time can be shortened by 40-60%, the probability of cracking of the floor timber can be reduced by more than two times, the surface of the dried floor timber can be more smooth, and the drying technology has good popularization and application values.

Description

technical field [0001] The invention belongs to the technical field of wood processing, and in particular relates to a drying process for floor wood. Background technique [0002] Floor wood must be pretreated before it is put into use, and among them, wood drying is an important link and the most critical process in the first step; the quality of drying directly affects the utilization rate of wood and the processing of subsequent processes, directly It affects the final quality of wood products. [0003] The wood with a thickness of no more than 13cm is used to make the floor. The drying method in the prior art mostly adopts the kiln drying method, that is, the floor wood is piled up in the drying kiln, and the air in the kiln is repeatedly and alternately heated and steam is sprayed into the kiln. The air and steam in the kiln are circulated to dry the floor wood. Since the best drying standard for the floor wood cannot be grasped, various data settings are unreasonable ...

Problems solved by technology

[0003] The wood with a thickness of no more than 13cm is used to make the floor. The drying method in the prior art mostly adopts the kiln drying method. The air and steam in the kiln are circulated to dry the floor wood. Since the best drying standard for the floor wood cannot be grasped, various data settings are unreasonable during the drying process. There are problems such as cracking, warping, and deformation of the floor wood. At the same time, the drying efficiency of this method is not high and the energy consumption is large
