Problems solved by technology

[0003] Most of the wood drying methods in the prior art use the kiln drying method, that is, the wood is piled up in the drying kiln, the air in the kiln is repeatedly heated and steam is sprayed into the kiln, and the air and steam in the kiln are circulated by blasting to dry the wood. Since the best drying benchmark for wood cannot be grasped, various data settings are unreasonable during the drying process, causing the wood to dry during the heating stage, which will eventually cause problems such as cracking, warping, and deformation of the wood. At the same time, the drying method of this method Low efficiency, high energy consumption

Embodiment 1

[0024] A method for drying wood, comprising the steps of:

[0025] (1) Wood pretreatment:

[0026] Cut the wood according to the processing requirements, and then rinse the sawdust and other impurities with clean water before use;

[0027] (2) Pre-drying treatment:

[0028] Put the wood treated in step (1) into the drying room, keep the temperature at 58°C, and the relative air humidity at 50-53%, and dry the wood until the water content is 50-53% for later use;

[0029] (3) Deep drying treatment:

[0030] After the surface of the wood treated in step (2) is coated with a layer of dry powder, it is then placed in an ultrasonic drying chamber for ultrasonic drying of the wood. The relative humidity is 45~48%, just dry the wood until the water content is not more than 10%; the dry powder is made of the following parts by weight: 15 parts of diatomite, 10 parts of bentonite, 6 parts of stearic acid Calcium, 14 parts of silica gel, 5 parts of grafted acrylamide, 6 parts of sod...

Embodiment 2

[0040] A method for drying wood, comprising the steps of:

[0041] (1) Wood pretreatment:

[0042] Cut the wood according to the processing requirements, and then rinse the sawdust and other impurities with clean water before use;

[0043] (2) Pre-drying treatment:

[0044] Put the wood treated in step (1) into the drying room, keep the temperature at 63°C, and the relative air humidity at 53-55%, and dry the wood until the water content is 53-55% for later use;

[0045] (3) Deep drying treatment:

[0046] After the surface of the wood treated in step (2) is coated with a layer of dry powder, it is then placed in an ultrasonic drying chamber for ultrasonic drying of the wood. The relative humidity is 48~50%, just dry the wood until the water content is not more than 10%; the dry powder is made of the following parts by weight: 20 parts of diatomite, 15 parts of bentonite, 8 parts of stearic acid Calcium, 18 parts of silica gel, 7 parts of grafted acrylamide, 10 parts of so...

Abstract

The invention discloses a wood material drying method and belongs to the technical field of wood processing. The wood material drying method specifically comprises the following steps: (1) pre-treating a wood material; (2) pre-drying the wood material; (3) deeply drying the wood material; and (4) performing after treatment after the wood material is dried. The method disclosed by the invention can commendably prevent phenomena of deformation, cracking and flexure of the wood material in a drying process and can also shorten the drying time by 30% to 35%; the cracking probability of the wood material is reduced by more than two times; and the surface of the dried wood material is smoother, so the wood material drying method has quite good promotion and application values.

Description

technical field [0001] The invention belongs to the technical field of wood processing, and in particular relates to a wood drying method. Background technique [0002] 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 affecting It affects the final quality of wood products. [0003] Most of the wood drying methods in the prior art use the kiln drying method, that is, the wood is piled up in the drying kiln, the air in the kiln is repeatedly heated and steam is sprayed into the kiln, and the air and steam in the kiln are circulated by blasting to dry the wood. Since the best drying benchmark for wood cannot be grasped, various data settings are unreasonable during the drying process, causing the wood to dry during the heating stage, which will eventually cau...
