I. Analysis of Microwave Tunnel Heating Advantages:

The microwave tunnel kiln is mainly used for firing non-metallic materials in an air atmosphere. Since materials are loaded on kiln cars, the length of the heating zone is not limited, and material shapes can be diverse (powder, granules, sheets, cylinders). This equipment utilizes microwave penetration for internal heating, ensuring uniform heating, high product quality, flexible process adjustment, simple operation, and high single-unit capacity.

Microwave High-Temperature Tunnel Kiln, Farewell to Traditional Heating Equipment

1. Heating Method and Efficiency

- Microwave Tunnel Kiln: Uses microwaves to cause high-frequency vibration and friction of molecules inside the material, achieving volumetric heating. It heats rapidly and uniformly, significantly shortening production cycles and improving efficiency.

- Traditional Tunnel Kiln: Generates heat through combustion or resistance, transferring it to the material externally via conduction and convection, resulting in temperature gradients and relatively slower heating speeds.

2. Temperature Control Precision

- Microwave Tunnel Kiln: Allows precise temperature control by adjusting microwave power, achieving high precision of ±1°C, ensuring product stability and consistency.

- Traditional Tunnel Kiln: Affected by heating processes and airflow distribution, temperature control precision is relatively lower.

3. Energy Utilization Efficiency

- Microwave Tunnel Kiln: Microwave energy acts directly on the material, with minimal heat loss to the kiln body and environment. Energy utilization is high, typically over 80%.

- Traditional Tunnel Kiln: Some heat is lost through exhaust gases, with energy utilization usually between 40% - 50%.

4. Environmental Performance

- Microwave Tunnel Kiln: No fossil fuel combustion required, no exhaust emissions, environmentally friendly.

- Traditional Tunnel Kiln: Heating produces pollutants such as carbon dioxide, sulfur dioxide, and nitrogen oxides, requiring additional environmental treatment equipment.

5. Product Quality

- Microwave Tunnel Kiln: Uniform heating ensures consistent internal structure, reducing internal stress and defects, improving product quality and performance.

- Traditional Tunnel Kiln: Non-uniform heating may lead to variations in product quality.

II. Characteristics of Microwave Tunnel Heating Equipment:

Microwaves are a form of electromagnetic waves. Under the influence of a high-frequency microwave electromagnetic field, polar molecules in dielectric materials generate intense friction to produce heat. Materials absorb microwave energy and generate heat internally, making the object itself the heat source. Microwave heating is the opposite of conventional heating, being a non-contact internal heating method. Thus, microwave heating involves the entire material heating itself without the need for heat conduction. Conventional heating relies on radiation, convection, and conduction, transferring heat from the outside in, resulting in high heat loss, low efficiency, prolonged heating times, hindered heat transfer to the center, and issues like external burning and internal cooling. This leads to large exhaust treatment volumes, extensive kiln infrastructure, rough production environments, frequent shutdowns for maintenance, and time-consuming repairs.

Microwave heating features rapid heating, selectivity, catalytic properties, non-contact between heat source and material, ease of automation, and energy savings. Therefore, microwave heating equipment is energy-efficient (high thermal conversion efficiency, over 30% energy savings compared to traditional methods), environmentally friendly (no emissions, reduced harmful substances), clean (materials heat themselves without contact contamination, improving product quality and yield), and highly efficient (fast heating, high energy utilization). Additionally, ZhongSheng's microwave industrial equipment operates at temperatures up to 1600°C, with stable temperature uniformity of ±10°C inside the kiln. The equipment easily integrates with automated and intelligent systems, improving the production environment.

III. Quality Advantages of ZhongSheng Thermal Energy Microwave Industrial Equipment:

A. Possesses independent intellectual property rights. All company products have their own patents, currently holding 12 national invention patents and 57 national utility model patents.

B. Company technology and products are industry-leading. Through product appraisal meetings organized by the Hunan Economic and Information Commission and the Hunan Resource Comprehensive Utilization Association, it was unanimously recognized that these three products have reached leading domestic technological levels. The company's microwave heating kiln technology has been included in the National Development and Reform Commission's Energy-saving Technology Promotion Catalog (Fifth Batch). Purchases of our industrial products may qualify for national subsidies.

C. High configuration, high standards, and new technology ensure product quality. ZhongSheng uses 1.5KW industrial-grade microwave sources with continuously adjustable power (0.1~1.49kW), ensuring uniform, adjustable, and controllable cavity temperatures to meet various technical process requirements and guarantee 24-hour uninterrupted operation. Other manufacturers typically use 1.2KW or 1.0KW household-grade microwave systems (unsuitable for 24-hour operation) with non-adjustable power, unable to ensure uniform, controllable, or adjustable cavity temperatures, nor meet diverse process needs. ZhongSheng employs crack antenna feeding to ensure uniform microwave fields and prevent microwave reflection from damaging magnetrons, enabling 24-hour continuous use and long service life (magnetron lifespan is generally affected by reflected power and cooling methods). Additionally, vulnerable parts (magnetrons) can be replaced without shutdown and without microwave leakage. Most manufacturers use direct microwave feeding, which struggles to achieve uniform cavity temperatures and does not allow online magnetron replacement without shutdown.
