The current situation and future development trends of the wood drying industry in 2023
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.
