Microwaves are electromagnetic waves. Microwave energy (heating) has been used in the chemical industry for many years for many diverse applications due to its advantages like volumetric heating, high power density, and fast, easy temperature control. These advantages of microwave technology are beginning to facilitate the production of clean, fast and high-quality products. The high heating rate can be several orders of magnitude greater than with conventional heating and microwave generators can respond quickly to changes in process parameters with a feedback loop of an automated process for things that have been used as a heating source in many applications, especially chemical processing.
The frequency of microwave heating is typically at 900 MHz and 2450 MHz and microwaves interact in three ways with different materials. It is reflected by conductors, transmitted by perfect insulators, or absorbed and decayed on the way inside materials – depending on their dielectric properties. Microwave heating results from induced currents so the heating tends to be volumetric. However the penetration of microwaves is influenced by the properties of the material. As the field penetrates, it losses power and therefore the field intensity will decrease, suggesting that heating may not be uniform. Challenges such as controlling the electromagnetic field and uniformity, and temperature measurements, often require more sophisticated approaches to be tackled.
Normally, a microwave expert is an electrical engineer who can calibrate and tune the microwave unit using a network analyzer. The expert can design systems using electromagnetic field simulation software such as Microwave Studio,® a powerful and easy to use software for high-frequency range. These help overcome microwave challenges like arcing. At Lee Enterprises Consulting, we have a number of highly qualified microwave energy experts available to assist you with any related matters.
