Embodiment 1

[0027] as attached Figure 1~2 As shown, the soft wood rapid drying kiln of the present invention includes a kiln body 1, a fan 4, a heater 3 and an evaporation water tank 2 are arranged in the kiln body 1, and a moisture discharge window 5 is arranged on the top for removing humid air in the kiln body. , the top of the kiln body is also provided with an explosion-proof window 6, which is used to adjust the pressure difference formed when the fan is started, so as to prevent the pressure difference in the kiln body from being too large and damage the kiln body. The fan 4 is a fan with a diameter of 1.8 meters. The rapid drying kiln of the present invention also includes a control system, which is used to control the opening and closing of each electric control component and control parameters such as time and temperature of each stage. A kiln door 7 is arranged on the side of the kiln body for feeding materials.

Abstract

The invention relates to the technical field of wood drying, in particular to a quick drying kiln for soft wood and a drying method thereof. A moisture discharge window is set, an explosion-proof window is set on the top of the kiln body, an evaporation water tank is set in the kiln body, and the fan is a fan with a diameter of 1.8 meters. The drying method includes the steps of preheating, drying and post-treatment. The pre-heating step keeps the temperature of the dry bulb and the wet bulb consistent. The drying step adopts a temperature gradient heating method, and the post-treatment includes cooling and humidity adjustment. The drying kiln of the invention can increase the life of the kiln body and reduce costs; the drying method has a fast drying speed, which not only ensures the quality of the wood during the drying process, but also reduces the degree of hardening of the wood surface, prevents the color of the wood from deepening, and improves the drying quality.

Description

technical field [0001] The invention relates to a fast drying kiln for soft wood and a drying method thereof. Background technique [0002] Conventional drying kilns are used to dry soft wood such as coniferous woods. The drying cycle is long, and the medium and low temperatures are likely to cause drying defects such as mildew. The drying effect is average and wood drying defects are easy to occur. Contents of the invention [0003] In order to solve the problems existing in the prior art, the invention provides a fast drying kiln for soft wood with good drying effect, long kiln body life and convenient installation. [0004] Another object of the present invention is to provide a fast drying method for soft wood with good drying effect and high speed. [0005] The quick drying kiln for soft wood in the present invention comprises a kiln body, a fan and a heater are arranged in the kiln body, a moisture discharge window is arranged at the top of the kiln body, an explosi...
