Active wood drying device

Abstract

The application discloses an active wood drying device comprising a kiln body, a fan and a heating device, wherein the top of the kiln body is provided with a passive dehumidification device; the active wood drying device also comprises an active dehumidification device which at least comprises an active dehumidification part arranged in the kiln body. The drying efficiency can be improved greatly, the drying cycle is shortened, and the drying energy consumption is reduced.

Description

technical field [0001] The application relates to the field of wood drying equipment, in particular to equipment that actively dries and realizes high-efficiency and high-quality drying. Background technique [0002] Wood is the only renewable material among the four basic raw materials. It has the characteristics of fast regeneration, natural, environmental protection and excellent performance. Wood runs through all aspects of human life with its irreplaceable functions. The drying treatment of wood is almost the longest and most energy-consuming process in the wood processing and manufacturing process, especially the existing drying process mostly uses high temperature and high humidity drying methods. For example, Chinese patent CN 103017485A discloses a high-temperature, high-humidity rapid drying process for wood, which includes: a step of humidifying and heating up, placing the wood in a drying kiln and closing the kiln door, opening the humidifying valve to quickly hu...

AI Technical Summary

Problems solved by technology

Although the above-mentioned technical solutions have effectively improved the drying efficiency and drying quality, they are still based on high-temperature and high-humidity drying methods. First, it takes a lot of energy to create a high-temperature, high-humidity drying environment; secondly, a high-temperature and high-humidity environment is not conducive to wood The discharge of internal moisture prolongs the drying cycle, generally 20 to 30 days (depending on the difference in material species), further increasing the energy consumption of drying

Long drying cycle and high drying energy consumption will increase the burden of raw material inventory and stagnation of cash flow, and increase the production cost of products for wooden enterprises.
