The experimental results show that the energy efficiency of this drying method can be used for convective drying, microwave drying and 80, and the maximum drying rate can reach 4.5% / min. Moreover, the dynamic law of true microwave combined convective...
In order to understand the microwave drying process correctly and improve the interaction between microwave and wood, the real-time detection of the existing problems, such as moisture content, etc. in basic theory research is carried out. The key to...
Abstract: The research achievements and application status of microwave drying equipment in wood drying, wood modification, adhesive synthesis, material defect detection, moisture content detection of bamboo and wood products and formaldehyde emission...
Wood microwave modification technology is to use a certain frequency of microwave partial or total treatment of wood, wood cell wall destroy the weak links of the pore membrane, improve the permeability, so as to dye, impregnate and other treatment....
Through reviewing the research and application of microwave drying equipment in China's wood industry, it can be seen that there are more researches on microwave drying technology and modification technology, and less on product quality testing. However,...
Abstract: The dynamic distribution of moisture content in black walnut wood during microwave drying and conventional hot air drying was analyzed and compared by means of X-ray scanning moisture content distribution test. In the whole microwave drying...
Materials and methods Experimental materials The experimental material is raw black walnut timber with the sawn timber size of 2000 m m(length)*30 m(thickness)*natural width. Before the experiment, the sawn timber was processed into small specimens with...
The uniformity of field intensity distribution is also closely related to the drying quality of wood. When the microwave field intensity distribution is not uniform, the temperature distribution in wood is not uniform, especially at the end of drying, the...
Abstract: The main causes of wood microwave drying defects were analyzed from the aspects of wood dielectric properties, microwave penetration depth, microwave equipment and drying technology, and the prevention measures were discussed from the aspects of...
