Microwave Drying and Sterilization Equipment is a new type of industrial equipment that integrates high-efficiency drying and low-temperature sterilization functions. Relying on the unique mechanism of microwave energy, it achieves integrated \"drying + sterilization\" operations and is widely used in fields with strict requirements for quality and hygiene, such as food, pharmaceuticals, chemicals, and agricultural by-products. Its core advantage lies in breaking through the limitations of traditional processes, providing solutions for industry production efficiency improvement and upgrading with its green energy-saving and precise controllable characteristics.

The core working principle of the equipment is based on the synergistic effect of the thermal and non-thermal effects of microwaves. Using industrial standard frequencies (mainly 2450MHz±50MHz), high-frequency microwaves generated by magnetrons penetrate the material, causing internal polar molecules (such as water molecules) to vibrate and friction at a frequency of tens of billions of times per second, instantly generating heat to achieve \"inside-out\" volumetric heating without the need for heat conduction. In the drying process, internal moisture in the material quickly vaporizes and is promptly discharged through the dehumidification system, with drying speed increased by more than 50% compared to traditional hot air processes; in the sterilization process, microorganisms' protein structures are destroyed through thermal effects, and non-thermal effects interfere with microbial cell membrane potential and oxidize cell enzyme systems, achieving a sterilization rate of ≥99.99% at a low temperature of 40-60℃, effectively killing harmful microorganisms such as bacteria, mold, and spores.

Compared with traditional segmented processes, the equipment has multiple technical advantages. First, it is highly efficient and energy-saving, with energy consumption reduced by 30%-60% compared to hot air and steam processes. Drying 10mm thick Chinese herbal medicine extracts only takes 3-4 hours, far exceeding the efficiency of traditional processes (8-12 hours), and microwave leakage is ≤5MW/c㎡, meeting national safety standards. Second, it ensures controllable quality. Through rotating trays, multi-feed waveguide design, and PLC intelligent control system, the temperature uniformity standard deviation is ≤0.8℃, avoiding local overheating, with heat-sensitive component retention rate over 95%, thus maximizing the preservation of food flavor, pharmaceutical active ingredients, and original material color. Third, it optimizes the process. No additional sterilization equipment is needed, as dehydration and inactivation are completed simultaneously in the same system, reducing material transfer links, lowering the risk of secondary contamination, and significantly shortening production cycles.

The equipment is adaptable to multiple industry scenarios with extremely broad application scenarios. In the food industry, processing fruit and vegetable chips, tea, and cured meat products can be completed in 30-120 minutes, doubling the efficiency of traditional processes while retaining the original taste and nutrition of ingredients. In the pharmaceutical industry, it can be used for drying and sterilizing Chinese herbal medicine extracts and antibiotic raw materials, with nitrogen protection function to prevent component oxidation, meeting pharmacopoeia microbial limits. In the chemical industry, it can avoid particle agglomeration when processing nanomaterials and ceramic raw materials, optimizing material dispersibility. The equipment models include box-type and tunnel-type, with output power options from 9-50KW and drying capacity from 15-200Kg/h, which can be flexibly customized according to production scale.

The equipment is equipped with a complete safety and control system. A dual-stage cooling system for high-voltage transformers supports 24-hour continuous operation. Infrared temperature measurement and adjustable power functions ensure precise process control, while door interlock switches and shielding devices ensure operational safety. As a green intelligent manufacturing equipment, microwave drying and sterilization equipment not only solves the pain points of traditional processes such as low efficiency, high energy consumption, and unstable quality but also meets environmental protection production requirements, having become a core equipment for quality improvement, cost reduction, and upgrading transformation in various industries.
