Wood microwave drying equipment is a device produced using new technology, which has a series of advantages such as uniform heating, fast drying speed, no deformation, good quality, and is conducive to continuous and automated production. Wood microwave drying equipment is different from traditional wood drying equipment. It is a high-frequency electromagnetic wave with a frequency of 300MHz to 300GMHZ, corresponding to wavelengths in the order of MM to DM (10-10M), longer than light waves and infrared waves. Microwaves have wave characteristics such as reflection, transmission, interference, diffraction, polarization, and energy transmission accompanying electromagnetic waves; The active molecules of the material, such as water molecules, are arranged, converted, and released at frequencies of 915 MHz and 2450 in an electromagnetic field to achieve the purpose of heating and drying. Wood microwave drying equipment heats materials simultaneously inside and outside, with the characteristic of instant heating and no thermal inertia phenomenon, making it easy to control during the drying process; And there is no noise or harmful gas emissions, which belongs to environmentally friendly drying technology. Simply put, it means that microwaves penetrate the interior of the material and are absorbed by the moisture and wood itself, directly heating it up. Due to the evaporation of surface moisture, the internal temperature of the material is higher than the surface temperature. By creating an outward pressure difference within the material, the surface migration of moisture is accelerated, resulting in microwave drying of wood being 20-30 times faster than convective drying, and reducing energy consumption by over 25% compared to far-infrared and steam drying. |
