How to realize dehydration of wood veneer dryer
2021-08-16 14:09:52

The drying and processing of wood veneer needs to reasonably control the basic water content of the product to avoid microbial reproduction and deterioration in the later stage. To realize long-term preservation, in the processing process of wood veneer dryer equipment, the activity of various enzymes of different raw materials is also limited due to drying. In addition, the effect of oxygen on wood veneer is also related to the moisture content. Its basic process is to transfer heat to raw materials and gradually transfer the moisture in raw materials, In the process of wood veneer drying process, there are both heat transfer and moisture outward movement. Therefore, the transfer of moisture and heat is the core and key of wood veneer drying process.

The drying methods of wood veneer are divided into natural drying and manual drying, which refers to the process of evaporating the water in wood veneer under natural and manually controlled conditions. Daily drying and air drying are natural drying methods, and the best method of manual drying is heat pump dryer hot air drying.


Wood veneer heat pump dryer wood veneer hot air drying is hot air convection drying, which is also carried out under normal pressure. When hot air is applied to wood veneer, heat is transferred to wood veneer, water is fully evaporated and gradually diffused to the surrounding space. At the same time, the wet body on the material surface and the drying air temperature of wood veneer are within the range of 50-60 ℃.

The heat pump drying room is dried by an atmospheric intermittent dryer with forced ventilation. The air is sucked into the drying room by the circulating fan. After heating and heating by the heater and filtering to remove the dust, it is loaded into the tray with materials, and then the moisture is removed by the dehumidification device. The material carrying body of the tray is relatively thin, only a few centimeters thick, It is to make full use of the contact between air and materials, and the hygroscopic hot gas can continue to be recycled after mixing with air, so as to improve the heat and product quality.
