I. Introduction to Microwave Heating and Drying:

Materials such as high-purity quartz sand and nano-carbon materials typically have small particle sizes, high density, compact structure, and poor thermal conductivity. Moisture trapped in micropores makes it difficult for heat to penetrate the material's core, and moisture evaporation is hindered. Conventional drying processes often fail to achieve complete dehydration and are time-consuming. External heat conduction methods have limited effectiveness in removing moisture from micropores. In contrast, microwave drying generates heat through molecular friction within the dielectric material. Water molecules absorb microwave energy, heat up, and rapidly evaporate, enabling deep and thorough moisture removal. This method is fast, non-contact, and avoids external contamination, preserving material purity. Therefore, microwave dehydration is particularly suitable for dense new materials requiring deep dehydration.

II. Application of Unique Microwave Heating Principles:

Microwave Heating Principle: Microwaves are a form of electromagnetic waves. Dielectric materials composed of polar and non-polar molecules, under the influence of a high-frequency microwave electromagnetic field, cause polar molecules to align with the electric field's polarity. This alignment, alternating with the microwave field, generates intense friction and heat. Microwave energy converts into thermal energy within the material, raising its temperature macroscopically. This is the fundamental principle of microwave heating. As a non-contact internal heating method, microwave heating causes the material itself to generate heat uniformly. Electromagnetic energy directly acts on molecular dipoles, converting into heat, and penetrates the material, heating both interior and exterior simultaneously without relying on heat conduction. The lack of heat dissipation internally creates a temperature gradient where the interior is hotter than the exterior, driving moisture or heat toward the surface. Conventional heating methods, such as thermal radiation, convection, and conduction, transfer heat from the outside in, resulting in high heat loss, low energy efficiency, uneven heating, prolonged heating times, and potential coking issues, necessitating regular furnace cleaning, shutdowns, and maintenance.

Microwave heating technology offers rapid heating, selectivity, catalytic effects, non-contact heating, ease of automation, and energy savings. Features of microwave industrial kilns include: Energy efficiency (high thermal conversion efficiency, saving over 30% energy compared to traditional methods), environmental friendliness (no emissions, reduced harmful byproducts), cleanliness (materials heat themselves without contact contamination, improving product quality and yield), and high thermal efficiency (fast heating, high energy utilization). Zhongsheng microwave industrial equipment operates at temperatures up to 1600°C, with stable temperature uniformity of ±10°C vertically and ±5°C furnace stability, easily integrating with automated and intelligent operations.
