I. Technical Principle of Microwave Belt Drying

The microwave belt dryer combines microwave heating with belt conveyor technology. As an electromagnetic wave with frequencies ranging from 300 MHz to 300 GHz, microwaves possess unique heating characteristics. When microwaves act on materials, polar molecules within the material, such as water molecules, rapidly vibrate and rub against each other under the high-frequency alternating electric field of the microwaves. This intense molecular movement generates a significant amount of heat, causing the material's internal temperature to rise quickly, achieving "internal heating." The material enters the dryer via a continuously operating conveyor belt and moves uniformly through the microwave field. During this process, microwaves continuously act on the material, converting moisture into water vapor that escapes. The speed of the conveyor belt can be adjusted according to the drying requirements of the material, ensuring it is dried within an appropriate timeframe.

II. Advantages of Microwave Belt Drying and Dehydration Process

1. Rapid: The internal heating method of microwaves eliminates the traditional heat conduction mode from the outside in. The entire material is heated simultaneously, allowing moisture to evaporate quickly. This significantly improves drying efficiency, saving several times more time compared to conventional drying methods.

2. Uniform Heating: Microwaves are evenly distributed in the drying space, ensuring balanced heating across all parts of the material. This effectively avoids localized overheating or uneven drying, resulting in stable and uniform product quality.

3. Energy Saving and Reduced Consumption: Microwaves directly generate heat within the material, reducing heat loss during transmission. Additionally, the equipment quickly reaches the set temperature without prolonged preheating, significantly lowering energy consumption.

4. Continuous Production: The belt conveyor structure enables continuous input and output of materials, making it suitable for large-scale industrial production. It can seamlessly integrate with upstream and downstream production lines, improving production efficiency and automation.

5. Gentle Drying: Compared to high-temperature hot air drying, microwave drying can be completed at relatively lower temperatures. This is particularly beneficial for heat-sensitive materials such as food, pharmaceuticals, and biological products, preserving their nutritional components, active substances, and flavor to the greatest extent.

III. Technical Advantages of Zhongsheng Microwave Drying Manufacturer:

(1) Possesses independent intellectual property rights. All of the company's products have their own patents. Currently, the company holds 12 national invention patents and 57 national utility model patents.

(2) The company's technology and products are among the industry's leading. Through product appraisal meetings organized by the Hunan Economic and Information Technology Commission and the Hunan Resource Comprehensive Utilization Association, it was unanimously agreed that the three products' technologies have reached leading domestic 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). Purchasers of the company's industrial products may receive certain subsidies from the government.

(3) High configuration, high standards, and new technology ensure product quality. Zhongsheng Company is equipped with 1.5KW industrial-grade microwave sources, with continuously adjustable power (0.1~1.49KW), ensuring uniform, adjustable, and controllable microwave cavity temperatures to meet different technical process requirements and guarantee 24-hour uninterrupted use. In contrast, other manufacturers typically use 1.2KW or 1.0KW household-grade microwave source systems (which cannot operate continuously for 24 hours) with non-continuously adjustable power, making it impossible to ensure uniform, controllable, and adjustable cavity material temperatures or meet different process requirements. In microwave heating equipment, Zhongsheng Company uses crack antenna feeding to ensure uniform microwave fields and prevent microwave reflection from damaging the magnetron, ensuring the magnetron can operate 24 hours without interruption and has a long service life (factors affecting magnetron lifespan generally include microwave reflection power and cooling methods). Additionally, vulnerable parts (magnetrons) can be replaced without stopping the machine, preventing microwave leakage. Most manufacturers use direct microwave feeding methods, making it difficult to ensure uniform cavity material temperatures and unable to achieve online replacement of magnetrons without stopping the machine.
