I. Introduction to the Application of Microwave Dynamic Drying and Dehydration Technology:

 The rotary microwave drying equipment uses a screw rotation to push the material forward and turn it over, allowing it to absorb microwave radiation heat energy to rapidly heat up and evaporate moisture. During this drying process, the material remains dynamic and evenly absorbs microwave heat energy, resulting in fast heating, drying, and dehydration. Moisture evaporation is more easily released from the bottom of the material. Therefore, the rotary microwave drying structure is mainly suitable for the dehydration of free and crystalline water in various inorganic and organic non-metallic powder materials and chemical raw materials. Depending on the actual situation of the equipment user, pure microwave heating or a combination of microwave and hot air heating can be selected. Compared to traditional drying equipment, this equipment has a simpler structure, large daily processing capacity, small footprint, high production efficiency, and energy savings of over 40%. Rotary microwave drying equipment is suitable for chemical raw materials, powder materials, chemical minerals, fine chemicals, organic chemical raw materials, inorganic chemical raw materials, chemical fertilizers, polymer polymers, coatings and inorganic pigments, dyes and organic pigments, food and feed additives, catalysts and chemical auxiliaries, adhesives, new energy materials, chemical reagent products, and more!

II. Features of Microwave Drying Equipment:

 In rotary microwave drying equipment, the material itself (powder, granules, or small items of any shape) acts as the dielectric medium. Under the influence of the microwave high-frequency electromagnetic field, polar molecules shift from their original random distribution to align according to the polarity of the electric field. The polar molecules in the medium transition from their original thermal motion state to following the alternating microwave electromagnetic field, generating intense friction and producing heat. In this microscopic process, microwave energy is converted into thermal energy within the medium, causing the temperature of the medium to rise macroscopically. This is the basic principle of internal microwave heating. The material itself becomes the heat source, rapidly and effectively removing crystalline and free water.

 ZhongSheng Rotary Microwave Dynamic Drying Equipment differs from ordinary microwave drying equipment. To save costs, general manufacturers use low-power, standard microwave sources, designed with a point-to-point direct radiation energy dissipation method and mechanical temperature control operation. This results in large temperature fluctuations, unstable energy supply. In contrast, ZhongSheng Thermal Energy uses a special slotted antenna energy feeding device to ensure uniform microwave energy field heating and avoid microwave reflection damaging the magnetron. Industrial-grade microwave sources are used, with continuously adjustable heating power and digitally controlled power adjustment, ensuring the microwave cavity heats evenly, adjustably, and controllably. This allows the magnetron to operate 24 hours non-stop, with a long service life for the main heating components, and overall equipment stability and durability.

III. Quality of ZhongSheng Microwave Drying Equipment:

1. Possesses independent intellectual property rights. All of the company's products have their own patents. Currently, the company holds 12 invention patents and 22 utility model patents.

2. The company's technology and products are at the industry's forefront. Through product appraisal meetings organized by the Hunan Economic and Information Technology Commission and the Hunan Resource Comprehensive Utilization Association, experts unanimously agreed that the three products—"RWEG Microwave (Electric) High-Temperature Push Plate Kiln, RWET Microwave (Electric) High-Temperature Roller Hearth Kiln, and RWS Microwave Multi-Function Experimental Furnace"—have reached the domestic advanced level. The company's microwave heating kiln technology has been selected for the National Development and Reform Commission's Energy-Saving Technology Promotion Catalog (Fifth Batch). Purchases of the company's industrial products may qualify for subsidies from relevant ministries.

3. High configuration, high standards, and new technology ensure product quality. ZhongSheng Company uses a 1.5KW industrial-grade microwave source with continuously adjustable power (0.1~1.49KW) to ensure uniform, adjustable, and controllable temperature in the microwave cavity, meeting the requirements of different technical processes and ensuring 24-hour uninterrupted use. In contrast, other manufacturers generally use 1.2KW or 1.0KW household-grade microwave source systems (which cannot operate continuously for 24 hours) with non-adjustable power, unable to ensure uniform, controllable, and adjustable material temperature in the cavity, nor meet the requirements of different processes. ZhongSheng Company uses a slotted antenna energy feeding system to ensure a uniform microwave field and prevent microwave reflection from damaging the magnetron, allowing the magnetron to operate 24 hours non-stop with a long service life (the lifespan of the magnetron is generally affected by microwave reflection power and cooling methods). Additionally, wearable parts (magnetrons) can be replaced without stopping the machine, without causing microwave leakage. General manufacturers use direct microwave energy feeding methods, making it difficult to ensure uniform material temperature in the microwave cavity and unable to achieve online replacement of the magnetron without stopping the machine. The company uses microwave leakage prevention devices: microwave leakage does not exceed 1mW/cm² (industry standard is no more than 5mW/cm²).
