Microwave drying equipment dehydration efficiency

Microwave Drying Equipment Drying and Dehydration Efficiency, Zhongsheng Has Stronger Technical Strength

I. Principle of Microwave Drying and Dehydration Technology:

Microwave thermal energy directly acts on the medium molecules and converts into heat energy. Due to the penetration capability of microwaves, the medium is heated both internally and externally simultaneously without the need for heat conduction, resulting in extremely fast heating speeds. For materials with a moisture content below 30%, the drying speed can be shortened by hundreds of times. Regardless of the shape of the object, since the object is heated both internally and externally, the temperature difference between the inside and outside of the material is small, and the heating is uniform, avoiding the situation of external charring and internal rawness that occurs in conventional heating, thereby improving drying quality. Microwave heating replaces the original coal, electricity, and gas heating modes, saving more than 30% of energy; for every 1 kWh of electricity saved, it saves 0.4 kg of standard coal and reduces carbon dioxide emissions by 0.997 kg. The era of microwave heating has arrived, and microwave heating is becoming the new generation of heating technology in the 21st century!

II. Technical Advantages of Zhongsheng Microwave Drying Equipment:

1. Possesses independent intellectual property rights. All of the company's products have their own patents. Currently, the main patents applied to microwave drying equipment include Patent No. ZL201120284899.6 for a high-temperature resistant microwave belt drying kiln, Patent No. ZL201120284906.2 for an open microwave suppressor, and Patent No. ZL201120535805.8 for a crack antenna for microwave kilns, among other patented technologies.

2. Has a strong technical team. The company currently has 65 engineering technicians with bachelor's degrees or higher, including 15 doctoral and master's degree holders, and 2 professors, covering talents in multiple disciplines and fields such as microwaves, electrical engineering, machinery, automation, system control, materials, chemical engineering, software, and more.

3. The company's technology and products are at the forefront of the industry.

3.1 The company's "Industrial Microwave/Electric Hybrid High-Temperature Heating Kiln Technology" passed a technical achievement appraisal organized by the Hunan Science and Technology Department. The technology was evaluated by an appraisal committee composed of 7 senior experts from energy, new materials, electronic information, thermal engineering, automatic control, metallurgy, and refractory materials, and concluded that "the technology of this achievement is at the domestic leading level."

3.2 The three products derived from the "Industrial Microwave/Electric Hybrid High-Temperature Heating Kiln Technology"—"RWEG Microwave (Electric Heating) High-Temperature Roller Hearth Kiln, RWET Microwave (Electric Heating) High-Temperature Pusher Plate Kiln, and RWS Microwave Multi-functional Experimental Furnace"—successfully passed the product appraisal organized by the Hunan Economic and Information Technology Commission and the Hunan Resource Comprehensive Utilization Association. The participating experts unanimously agreed that the technology of these three products has reached the domestic leading level.

3.3 The company's microwave heating kiln technology was selected for the National Development and Reform Commission's Key Energy-Saving Technology Promotion Catalog (Fifth Batch). Purchasing our company's industrial products may qualify for certain subsidies.

4. Has many successful cases. The company's microwave drying equipment, at Jiujiang Huaxin Nonferrous Metals Co., Ltd. (formerly Jiujiang Jinxin), ordered two tantalum-niobium microwave drying lines from our company. The equipment has been running stably, meeting design indicators, and receiving positive feedback from users.

5. Zhongsheng Thermal Energy's microwave industrial equipment is equipped with a 1.5KW industrial-grade microwave source, with continuously adjustable power (0.1~1.4kW), to ensure that the microwave cavity temperature is uniform, adjustable, and controllable, meeting the requirements of different technical processes and ensuring 24-hour uninterrupted use. Other manufacturers generally use 1.2KW or 1.0kW household-grade microwave source systems (which cannot operate continuously for 24 hours) and cannot continuously adjust power, making it impossible to ensure uniform, controllable, and adjustable material temperature in the cavity, nor to meet the requirements of different processes.

6. Zhongsheng Thermal Energy's microwave drying equipment uses microwave antenna feeding, ensuring uniform microwave fields and preventing microwave reflection from damaging the magnetron, enabling the magnetron to operate 24 hours a day without stopping, with a long service life (the lifespan of the magnetron is generally affected by microwave reflection power and cooling methods). At the same time, wearing parts (magnetrons) can be replaced without stopping the machine, without causing microwave leakage. General manufacturers use direct microwave feeding methods, making it difficult to ensure uniform material temperature in the microwave cavity, and also unable to achieve online replacement of magnetrons without stopping the machine.

7. Special microwave leakage prevention device: microwave leakage does not exceed 1mW/cm² (far below the required standard of 5mW/cm², GB10436-89, "Microwave Radiation Standard for Workplaces"), improving production safety, while other manufacturers generally only meet national standards. The furnace cavity is equipped with an inspection door to allow personnel entry, and the inspection door is equipped with a safety interlock switch (limit switch mode) that can quickly and automatically cut off the microwave power in case of faulty operation to prevent microwave leakage. Each section of the microwave box is equipped with an observation window, the material inlet and outlet are equipped with microwave suppressors, and the equipment inlet, outlet, and middle are equipped with online microwave leakage detectors that automatically alarm when microwave leakage exceeds the standard.

8. The main components of the equipment, PLC and human-machine interface touchscreen, use well-known brands such as Siemens, ABB, or Schneider. The operation requires two modes: automatic and manual; the CPU module provides an Ethernet communication interface to connect to the user's centralized monitoring system. A well-known brand human-machine operation interface displays equipment parameters and alarm conditions on the operation panel, detailing various equipment fault points; human-machine operation interface: main interface; operating condition interface (automatic mode interface); manual operation mode interface; I/O point interface; fault history record; parameter setting interface.

9. The equipment is equipped with an exhaust and dehumidification system, and the fan uses frequency conversion control, allowing the required dehumidification air volume to be arbitrarily adjusted through the frequency converter, flexibly adjusting the air volume and air pressure.

10. All electrical equipment has safety protection measures such as insulation and leakage protection, and their own protection level meets environmental requirements, ensuring normal operation in low-temperature and high-humidity environments. All motor cables and signal multi-core control cables from the control cabinet to the equipment's electrical point field junction boxes use special cables to better achieve insulation, wear resistance, and bending resistance. The inside of the control cabinet uses BVR series single-core multi-strand wires.
