Animal incinerator: dual guarantee of environmental protection and epidemic prevention

    In the current rapid development of large-scale aquaculture, the harmless treatment of animal carcasses has become a key link related to public health safety and ecological environment protection. According to industry statistics, the mortality rate of pig farming from birth to slaughter is about 10%, and the normal mortality rate of poultry is between 8% and 10%. The number of livestock and poultry carcasses produced every day in the country is astonishing. If not handled properly, it can not only cause the spread of malignant diseases, but also cause long-term damage to the ecosystem through underground water source pollution, air pollution, and other means. Traditional landfill, composting and other methods are difficult to meet the efficient and environmentally friendly needs of modern aquaculture due to their long processing cycles, high risk of secondary pollution, and large land occupation. In this context, animal carcass incinerators have gradually become the core technology equipment for harmless treatment with their advantages of completely inactivating pathogens, significantly reducing capacity, and energy recovery. Modern incinerators have successfully overcome the pain points of high energy consumption, heavy pollution, and complex operation in traditional incineration methods through the innovation of gasification incineration principles, secondary combustion chamber design, and intelligent control systems. For example, the gasification incinerator developed by Zhejiang Shengzhou Keling Machinery Co., Ltd. can process 500 kilograms of animal carcasses at once, completely turn them into ashes within 4 hours, and achieve colorless and odorless emissions, effectively preventing secondary pollution. With the increasingly strict environmental regulations, this technology equipment has evolved from a simple processing device to an indispensable environmental protection system for breeding farms, slaughterhouses, laboratories, and other places.

    The core technological breakthrough of modern animal incinerators lies in the design of a dual chamber staged combustion structure, in which one combustion chamber (600-850 ℃) is responsible for the primary pyrolysis and volatile release of animal carcasses, allowing organic matter to decompose into combustible gases in an anaerobic environment, while the structure of pathogenic microbial cells begins to disintegrate; Subsequently, the flue gas enters the secondary combustion chamber at 850-1100 ℃, where toxic substances such as   dioxins are thoroughly decomposed and pathogens are completely inactivated through ultra-high temperature retention for ≥ 3 seconds. Experiments have shown that the inactivation rate of African swine fever virus and other pathogens exceeds 99.99% at this temperature. The innovative gasification incineration technology utilizes the high calorific value characteristics of animal carcasses (about 3500Kcal/Kg), which are mixed and burned with a small amount of coal in a special gasifier. After being ignited by electric ignition, oil is released and cracked into combustible gas, which is transported through pipelines to form a jet flame. This energy self-sustaining design reduces fuel consumption by 30% -50% (such as reducing the processing cost of a breeding farm in Zhejiang from 180 yuan/100kg to 95 yuan). The waste heat can also be used for resource recycling such as boiling water and cooking feed. To ensure clean emissions, advanced equipment uses a fire curtain combustion system to form a 100mm thick 1000 ℃ high-temperature zone at the outlet of the secondary combustion chamber to oxidize residual harmful substances. Combined with a vortex oxygen replenishment device, it extends the retention time of flue gas through turbulence and accurately controls oxygen, successfully solving the traditional "black smoke problem" and achieving transparent emissions without black smoke, odor, and dust. Henan Yinchen Group's pet incinerator applies this technology to treat animal organs with 70% water content, which still meets environmental standards.

    In the prevention and control of highly infectious diseases such as African swine fever and avian influenza, incinerators play a key role with their rapid processing capabilities. For example, in 2021, when a large chicken farm experienced an outbreak of H5N1, the TQH-200 equipment was used to achieve "same day death, same day treatment". Within 48 hours, 3.5 tons of dead chickens were incinerated, reducing the exposure time to pathogens by 80%, effectively blocking virus transmission, and eliminating the risk of soil and groundwater pollution. Especially in rainy seasons or areas with high groundwater levels, it became the only reliable means. In terms of application in slaughterhouses, a large slaughterhouse in Beijing adopts a centralized incineration system to establish a full process supervision of "online declaration video monitoring incineration traceability": quarantine non-conforming products are pasted with RFID tags for refrigeration and temporary storage, electronic ledger is generated by scanning the code before incineration, real-time video monitoring process is recorded, and ash is detected and buried. This system reduces processing costs by 40% and meets the requirements of the supervision platform of the Ministry of Agriculture and Rural Affairs. At the same time, with the rise of the pet economy, professional institutions in cities such as Shanghai and Guangzhou have adopted the CX-30 small environmentally friendly incinerator to provide pet aftercare services. Its sliding furnace bed is easy to place the body, and the 25cm adjustable flame nozzle is suitable for different body types. The autonomous air intake system ensures no black smoke burning, and the exhaust purification meets residential standards. It only takes 30-40 minutes to process 10kg of dogs and obtain 0.5kg of pure ashes, achieving a balance between environmental protection and humanistic care.

    The development of animal incinerators marks the strategic transformation of harmless treatment from "passive response" to "active prevention and control". Modern equipment has systematically solved the pollution and efficiency problems in traditional treatment through the innovation of gasification incineration technology, intelligent control systems, and ultra-low emission design. Practical verification shows that the 800kg/time processing system of a regional processing center in Zhejiang has an annual processing capacity of over 5000 tons, which is equivalent to saving 15 acres of landfill land and blocking more than 20 zoonotic disease transmission chains, with significant environmental and epidemic prevention benefits. Future technologies will evolve towards intelligent operation and maintenance, modular deployment, and integration of new energy, achieving more efficient, clean, and inclusive upgrades. However, technological breakthroughs are only the starting point, and comprehensive coverage of harmless treatment of animal carcasses still requires precise policy guidance, dynamic improvement of standards, and coordinated promotion of public awareness. Only by ensuring that each animal carcass is properly disposed of can we build a solid foundation for public health and safety, and safeguard the sustainable development of harmonious coexistence between humans and nature.
