With the development of modern furniture industry, the improvement of wood drying equipment and the continuous progress of drying technology, the use of advanced technology to dry wood, shorten the furniture production cycle, has become a major issue faced by modern furniture enterprises. According to the furniture quality standard of light industry, "the wood moisture content of the product shall not be higher than 1% of the average wood moisture content of the area where the product is located." Furniture manufacturers need to strictly control the moisture content of wood to ensure the quality of furniture. Improper wood drying will directly affect the wood material and the service life of furniture. Therefore, how to choose a suitable and reasonable drying equipment has become a concern. Let's analyze several common wood drying equipment.
(1) the technical advancement, technical reliability and economic rationality should be considered, and according to the tree species, specifications and the quantity of dried wood, the requirements of wood use on drying quality and the specific situation of the production unit, etc.
(2) steam heating wood drying: wood drying equipment is a traditional and popular drying method at home and abroad. Its main advantages are stable technical performance, mature technology, easy adjustment and control of temperature and humidity. It can be used for central heating and drying various materials; The drying process is reasonable, the operation is correct, the drying quality is guaranteed and the drying chamber capacity is large.
(3) hot water heating wood drying: it has some advantages of steam drying. Wood processing residues can be used as fuel and the drying cost is greatly reduced. Due to the large heat capacity of hot water, the air condition in drying room is stable and easy to control.
(4) the main advantage of indirect heating wood drying with furnace gas is that the boiler is not used, the factory processing residue is used as energy, and the drying cost is low.
(5) the advantage of wood drying equipment is that the latent heat of vaporization released by condensation of wet air can be recovered; Moreover, the process is simple, the operation is easy, and the wood is generally not damaged.
(6) vacuum wood drying: the wood is put into a closed drying container, on the one hand, the temperature of the wood is increased, on the other hand, the pressure in the container is reduced, so that the moisture in the wood begins to evaporate at a relatively low temperature, so as to achieve the purpose of drying wood. This drying method is characterized by short drying cycle, good drying quality, high energy consumption, small container volume, and complex control of drying equipment and drying process. It is suitable for hard broad-leaved wood with good air permeability or thick board of easily shrinkable wood.
(7) microwave high frequency wood drying: the wood drying equipment has a series of advantages, such as simultaneous heating inside and outside, uniform heating, fast drying speed, short drying cycle, good drying quality, keeping the natural color of wood, and conducive to continuous automatic production.
(8) air energy heat pump wood drying advantages: heating function is self-evident; Humidity regulation (spray steam or atomized water) is used to ensure the high humidity environment required for some drying stages and to prevent wood cracking and deformation; Ventilators need to ensure that hot and humid air passes through
To select wood drying equipment, first of all, we should understand the characteristics and application scope of various drying methods, and then select the corresponding drying methods and types according to the specific conditions of the enterprise itself, and then cooperate with reasonable drying technology, so as to greatly reduce the equipment investment and drying cost under the premise of ensuring the drying quality.
