New Zealand wood drying industry

Since the reform and opening up, China's wood drying industry has achieved tremendous development, both in terms of the level of research and development of dry production processes and equipment. However, because the foundation is relatively weak, the overall level cannot meet the needs of national economic development. . During the inspection of New Zealand's forestry, wood processing industry and furniture industry, the author paid particular attention to examining the country's timber drying industry and felt that there are many references to the development and research of industrial fast-growing wood drying technology in the country.

New Zealand is a country that cultivates fast-growing materials in a large area by means of industrialized cultivation. It has 1.7 million hectares of radiata pine plantation, and radiata pine has been planted from seedlings to mature plants for about 25 years. Each year, New Zealand's radiata pine yields 17 million cubic meters worth of S$5 billion (equivalent to RMB 20 billion); it is planned that by 2025, radiata pine planting area will reach 3.5 million to 4 million hectares, and the wood output will be It reached 55 million to 60 million cubic meters. New Zealand attaches great importance to the utilization technology of radiata pine wood. It includes the production of wood (including the production of Glulam), drying, antisepsis, and joinery and furniture production. It also actively uses this high-quality wood-based panel raw material to vigorously develop the production of medium-density fiberboard. .

New Zealand Windsor Engineering Group Co., Ltd. Built in 1975. The existing staff of 95 people. The company's head office and factory are located in Wellington. At the same time, it has a wood processing technology and sales department in Rotera, South Island, New Zealand, and a project engineering and sales department in Albury, Australia.

Since 1980, the group has produced more than 200 drying kilns. Currently, 75% of wood in New Zealand is dried using these drying kilns. Wood drying equipment is the company's main product, and it also manufactures vacuum cleaners and environmental protection equipment. It is widely used in chemical and food processing industries. The dry kiln equipped by the Cryst's “New Century Woodworking Plant” in South Africa and the Solych Factory in Concepcion, South America, is a typical product of this company. The southern hemisphere is rich in pine wood and it is in great need of New Zealand's new type of wood. Drying technology to promote their use.

These types of drying kiln all have the same control system. In this case, the company has jointly developed the system with the New Zealand Forestry Research Institute and the New Zealand Institute of Electrical and Automation, and it has been continuously upgraded and upgraded. At present, this type of system is It has been able to connect with the Internet and remotely operate it on a global scale. For example, the drying problem that can occur in South Africa can be solved by a New Zealand drying expert through the Internet. This system can connect multiple drying kiln, and can control the kiln parameters such as the temperature and humidity of the hot and humid air and the moisture content of the dried wood at multiple points so as to control; it is very convenient to input various drying benchmarks, and can Various drying process parameters such as drying speed are automatically displayed. Drying time, moisture content of wood, temperature and humidity of drying medium, etc.; dynamic control of heat source and fan, specifically. For example, in the late drying period, the fan speed can be adjusted. To reduce energy consumption or to control the forward and reverse rotation of the fan, so as to facilitate uniform circulation of the air flow; automatically control the amount of hot water or hot water according to the benchmark requirements, so as to ensure the requirements of the benchmark and save energy; the entire system has a modem stand by.
