Embodiment 1

[0056] The drying method provided by the present invention mainly includes the steps of material selection, rounding, opening the stress relief groove 100, stacking and natural drying, drying in the kiln, and humidity control. The specific operations are as follows:

[0057] (1) Material selection and rounding. The round wood species selected in this embodiment is fast-growing poplar. The diameter of the log is 7 cm (with an error of ± 1 cm) and the length is 100 cm (with an error of ± 5 cm). Use a rotary cutter to round the logs with a thickness of 3 mm to remove branches, knots and bark on the surface of the logs.

[0058] (2) Stress relief grooves 100 with a length of 8% of the length of the round material (ie 8 cm), a width of 2 cm, and a depth of 2 cm are formed at both ends of the round material in the direction of the pith center (axis).

[0059] (3) Natural drying, choose a well-ventilated place without sunlight exposure for natural drying. When the moisture content...

Embodiment 2

[0080] The drying method provided by the present invention mainly includes the steps of material selection, rounding, opening the stress relief groove 100, stacking and natural drying, drying in the kiln, and humidity control. The specific operations are as follows:

[0081] (1) Material selection and rounding. Use a small-diameter eucalyptus log with a diameter of 10 cm (error ± 1 cm) and a length of 150 cm (error ± 5 cm), and use a rotary cutter to round the log with a thickness of 4 cm to remove the log Surface branches, knots, bark.

[0082] (2) Stress relief grooves 100 with a length of 10% of the length of the round material (ie 15 centimeters), a width of 3 millimeters and a depth of 3 centimeters are formed at both ends of the round material in the direction of the pith center.

[0083] (3) Dry naturally. Under atmospheric conditions, when the moisture content of the round wood is 40%, the natural drying is completed.

[0084] (4) The drying stage in the kiln. Use ...

Embodiment 3

[0099] The drying method provided by the present invention mainly includes the steps of material selection, rounding, opening the stress relief groove 100, stacking and natural drying, drying in the kiln, and humidity control. The specific operations are as follows:

[0100] (1) Material selection and rounding. Use a small-diameter fir log with a diameter of 12 cm (error ± 1 cm) and a length of 200 cm (error ± 5 cm), and use a rotary cutter to round the log with a thickness of 5 cm to remove the surface of the log branches, knots, bark.

[0101] (2) Open the stress relief groove 100 . In the direction of the pith center at both ends of the round material, a stress relief groove 100 with a length of 7.5% of the length of the round material (i.e. 15 centimeters), a width of 4 millimeters and a depth of 4 centimeters is formed.

[0102] (3) Dry naturally. Under atmospheric conditions, when the moisture content of the round wood is 45%, the natural drying is completed.

Abstract

The invention discloses a drying method for roundwood. The method comprises the following steps: selecting a log with the proper size and a tree and performing rounding treatment to obtain roundwood; separately forming stress release grooves in two ends according to the size of the roundwood; naturally drying the roundwood; putting the naturally dried roundwood in a drying kiln to be dried; and performing humidifying treatment according to use of the roundwood, and controlling the final water content of the roundwood. According to the drying method for roundwood, the growing stress and the drying stress of the roundwood are released by forming the stress release grooves, so that drying and cracking of wood are reduced; and by drying the roundwood, the wood which is dried is prevented from deforming, so that the drying quality and the outturn percentage of the wood are effectively improved. The technical problems that the drying defect is obvious and the outturn percentage is low in an existing wood drying technology are solved well.

Description

technical field [0001] The invention relates to the field of wood drying technology, in particular to a drying method applied in circular wood processing technology. Background technique [0002] In recent years, with the rapid development of my country's economy, people's mood to get close to nature, return to nature, and admire nature has become increasingly urgent, making solid wood products very popular among consumers in the market. For the furniture industry, traditional furniture substrate materials are no longer limited to particleboard, fiberboard and other boards. Furniture substrates such as solid wood ecological boards and solid wood finger-joint boards are gradually recognized by the market and consumers. [0003] However, because my country is a country with relatively scarce forest resources, the per capita forest resources are few. In order to solve the problem of scarcity of forest resources at the present stage, artificial fast-growing forests have been p...
