At present, the furniture industry is very mature, and whole-house customization is even more popular nowadays. However, when it comes to furniture production, we have to talk about the related issues of raw wood. In order to respond to the demand for environmentally friendly production, some wood raw materials will inevitably be lacking in the market, or the price will continue to rise.

In the process of wood production, wood drying is one of the most effective measures to improve the quality of wood products. On the whole, the level of wood drying equipment, drying process, drying technology, etc. on the market is uneven.

1. Commonly used wood drying methods

Diversified wood drying methods, but the proportion of standardized production is low

There are many kinds of wood drying methods. At present, the drying methods actually used in production mainly include conventional steam drying, high temperature drying (such as superheated steam drying), heat pump drying (dehumidification drying), solar drying, vacuum drying, high frequency drying, paraffin oil drying, etc. .

Production energy structure adjustment, drying costs continue to increase

With the continuous improvement of environmental protection requirements, many coal-fired boilers in enterprises must be shut down or planned to be shut down, and general-scale wood processing enterprises do not have the conditions to use large boilers.

In the past, many enterprises used waste wood as boiler fuel in the production process, but now many countries and regions also use biomass pellets as a restricted fuel, and the production cost of enterprises has risen sharply.

Intensive and large-scale production of wood drying is the development trend, but the number of small and medium-sized enterprises is still in the majority at this stage.

Developed countries or their timber factories in the world have used large-scale production to improve production efficiency, ensure production quality, and reduce costs at the same time in drying processing. At this stage, the proportion of small and medium-sized wood processing enterprises in many developing countries is still relatively high, and the industrial structure still needs to be transformed.

2. Development trends and suggestions for the wood drying industry

Under the situation that the cost of raw materials and production costs of enterprises are constantly increasing, enterprises should pay more attention to the scientific and reasonable formulation and strict implementation of drying processes. Large-scale production can better ensure the quality of wood after drying and control production costs.

Mainly focus on conventional drying, with coordinated development of various drying methods

Furniture enterprises should carry out a combination of various drying methods according to their own characteristics and policies and regulations. For example, if the raw material is easy-drying conifer wood, high-temperature drying and continuous drying can be used; if the raw material is difficult-to-dry wood, steam drying method combined with conventional drying method should be considered, Or high-frequency vacuum drying combined with conventional drying methods.

Enterprises should adopt the method of large-scale production and eliminate the methods with poor production capacity and drying effect

The adjustment of energy structure and the transformation of the industrial structure have brought challenges to the traditional wood drying industry but also brought new opportunities. Enterprises should quickly respond to the guidance of the market, seize the opportunity of industrial transformation and upgrading, and refer to the wood drying technology and other related technologies of large furniture enterprises. Through a variety of ways to develop large-scale production in important wood processing areas and wood import areas, eliminate outdated production methods and equipment, fundamentally solve problems in the drying production process, and control the quality of drying finished wood.

Improve the quality of drying equipment and adopt more scientific and efficient production methods

The most scientific and efficient methods for wood drying on the market are high-frequency drying and vacuum drying technology. For example, JYC's high-frequency wood vacuum dryer reduces the boiling point of water in a vacuum state, effectively ensuring that the wood is not easily deformed, non-discolored, or no cracked, In the drying process can make the moisture content of the whole wood inside and outside more uniform.

If the wood is dried by the traditional external conduction heating, it is easy to appear that the surface of the wood lacks moisture, but there is still a lot of moisture inside the wood, which leads to the deformation of the wood due to the internal tension of the wood after the finished furniture is made.

With the continuous improvement of international requirements for environmentally friendly production and the continuous increase of production costs, the future trend of the wood processing industry will still focus on environmental protection and technological innovation, and the development of more efficient and energy-saving drying equipment will also be the general trend of the industry!
