Industrial Microwave Dryer vs Conventional Dryer
YANTAI, China, January 8, 2016 (Newswire.com) - www.maxindustrialmicrowave.com
In conventional or surface heating, the process time is limited by the rate of heat flow into the body of the material from the surface as determined by its specific heat, thermal conductivity, density and viscosity. Surface heating is not only slow, but also non-uniform with the surfaces, edges and corners being much hotter than the inside of the material. Consequently, the quality of conventionally heated materials is variable and frequently inferior to the desired result.
Imperfect heating causes product rejections, wasted energy and extended process times that require large production areas devoted to ovens. Large ovens are slow to respond to needed temperature changes, take a long time to warm up and have high heat capacities and radiant losses. Their sluggish performance makes them slow to respond to changes in production requirements making their control difficult, subjective and expensive.
Conversely, with microwaves, heating the volume of a material at substantially the same rate is possible. This is known as volumetric heating. Energy is transferred through the material electro-magnetically, not as a thermal heat flux. Therefore, the rate of heating is not limited and the uniformity of heat distribution is greatly improved. Heating times can be reduced to less than one percent of that required using convention.
Recently, MAX Industrial Microwave have worked closer with Universities, Institutions and Research Organization, providing novel equipment solutions for environmental issues. We have also expanded out standard servicing facilities, to include the supply of high powered magnetrons, where customers can benefit discounted OEM prices. Further to our service extension we have also provided corrective solutions to improve reliability and performance of equipment.
