The Hong Kong Jockey Club Conghua Racecourse, a flagship project of Guangdong–Hong Kong cooperation, is the largest and highest‑standard international horse‑racing training facility in China, with animal health and biosecurity protocols aligned with world‑class benchmarks. To fortify the cross‑border equine transport quarantine system, Guangzhou Aogong Spray Equipment Co., Ltd., leveraging its technical expertise, successfully undertook the construction of the racecourse’s vehicle disinfection tunnel. Equipped with an intelligent high‑pressure misting system, this solution provides round‑the‑clock, all‑encompassing biosecurity protection for both horse‑transport vehicles and service vehicles.
I. International-Level Pandemic Prevention Requirements
The Conghua Racecourse serves as the core hub for cross-border horse training and round-trip transportation, with frequent cross-border movement of horses and extremely high biosecurity risks. The racecourse strictly adheres to Guangdong–Hong Kong integrated quarantine standards, requiring all inbound and outbound vehicles—including horse transporters and support vehicles—to undergo comprehensive disinfection, thereby preventing the introduction or spread of diseases via vehicular traffic. Traditional manual spraying suffers from uneven coverage, low efficiency, and excessive chemical waste, making it unable to meet international‑level biosecurity requirements for “seamless clearance, rapid disinfection, and end-to-end controllability.” There is an urgent need for automated, intelligent, professional spray‑disinfection solutions. Leveraging years of experience in livestock disease prevention and large‑scale facility disinfection, Guangzhou Aogong Spraying has been designated as the project’s official partner.
II. Vehicle Passage Disinfection Plan for the Austrian Worker’s Spray System
Overall requirements for project disinfection:
- It accommodates large specialized vehicles such as horse transport trucks, providing 360° full‑coverage disinfection of the vehicle body, tires, and chassis.
- Meets Customs’ “seamless inspection” requirements, with a fast and efficient disinfection process that ensures no delays.
- The equipment must be resistant to disinfectant corrosion and suitable for long-term outdoor operation.
The Guangzhou Aogong technical team has custom-designed it in accordance with the above requirements. Six-sided three-dimensional spray disinfection system The main structure features corrosion‑resistant stainless steel columns and piping, ensuring long‑term resistance to aggressive disinfectants such as chlorine‑based agents and peracetic acid. The system is equipped with high‑pressure misting columns paired with underbody spray nozzles, creating a three‑dimensional mist curtain that covers the upper, middle, and lower sections of the vehicle, leaving no blind spots—such as body gaps, the undercarriage, or the tires—unattended. In terms of control, the system integrates infrared sensors and a PLC‑based control unit: upon vehicle entry, misting activates automatically within 0.5 seconds, completing full‑vehicle disinfection in 15–20 seconds; once the vehicle departs, the system shuts down immediately, enabling unattended operation.
III. Project Outcomes: Strengthening the Lifeline of Epidemic Prevention at the Horse Farm
Since its commissioning, the disinfection tunnel has delivered outstanding performance, achieving 100% coverage and effectively eliminating bacteria, viruses, and parasite eggs, fully meeting the quarantine standards of both the racetrack and customs authorities. The time required to disinfect each vehicle has been significantly reduced, and in conjunction with the “one‑time approval, multiple round trips” clearance model, it enables vehicles to undergo instant disinfection and pass through seamlessly, ensuring efficient and smooth cross‑border transport. The system reduces water and chemical consumption by more than 70%, cuts manual disinfection costs by 60%, and boasts zero failures during outdoor operation with exceptional corrosion resistance. Since going live, it has effectively mitigated the risk of disease transmission, safeguarding the health and safety of thousands of purebred racehorses at the Conghua Racecourse and helping to maintain zero COVID‑19 cases and zero accidents in Guangdong–Hong Kong cross‑border horse racing logistics.
IV. Project Value: Setting a New Industry Standard for Epidemic Prevention
This project stands as a flagship example of Aogong Spraying’s expertise in biosecurity for high-end livestock operations and international sporting venues, showcasing the company’s technological prowess in intelligent spray‑based disinfection. It not only meets world‑class biosafety standards but also supports the efficient operation of large‑scale facilities, providing a benchmark for biosecurity across diverse settings such as racecourses, livestock farms, border quarantine stations, and slaughterhouses.
