A kind of mahogany drying method

Abstract

The invention discloses a rosewood drying method and belongs to the technical field of wood processing methods. The rosewood drying method includes the following steps that rosewood raw materials are cut in the radial direction and aired; the rosewood raw materials are neatly and densely arranged and then sent to a high-frequency vacuum wood drying device to be initially dried, slow heating is conducted, the temperature in the device is controlled within a specific temperature range, and continuous drying is conducted; then the rosewood is transferred into an indoor ventilation environment to be horizontally arranged; and finally, the rosewood is sent into an infrared drying device, the temperature is controlled to be within a specific temperature range, slow heating is conducted, and continuous drying is conducted. According to the above rosewood drying method, several drying methods are used in combination, the process is continuous and slow, and rosewood drying is more uniform; and a medium temperature is adopted for drying, heating is stopped after the temperature exceeds the upper temperature limit, rosewood grease components are prevented from being discharged massively, rosewood plant cell carbonization at the high temperature and fire hidden danger are avoided, moisture in the rosewood is effectively removed, meanwhile, grease in the rosewood is reserved, and the dried wood maintains the color and flexibility.

Description

technical field [0001] The invention belongs to the technical field of wood treatment methods, in particular to a mahogany drying method. Background technique [0002] The wood must be dried before fine processing to control the moisture content of the wood and prevent the deformation and cracking of the wood. As a precious wood, mahogany is widely used in the manufacture of high-end mahogany furniture because of its high hardness, long period of wood growth, and soft color, and its value is high. In order to ensure the quality and service life of mahogany furniture, as well as its applicability under different climate, temperature and humidity conditions in the north and south, mahogany materials must be dried carefully. [0003] Existing mahogany drying treatment method mainly contains two classes: (1) utilize chemical agent to carry out the method for high-temperature boiling of mahogany to carry out chemical dehydration. The typical literature of this type of method is...

Problems solved by technology

The typical literature of this type of method is: the application number is CN201510086375, the name is "a high-frequency vacuum wood drying device and method", and the high-frequency vacuum wood drying device is used for wood drying, but usually only the device is used alone for high-temperature drying. Dry, and there is no close contact between the wood, it will lead to uneven high-frequency current, and the uniformity of drying is limited; and the high temperature used is only suitable for the removal of moisture from ordinary wood with low oil content and no control of oil content Even carbonization, if high temperature conditions are applied to mahogany, it will lead to excessive discharge of mahogany oil, making mahogany lose its color and flexibility
