Ozone generator in Food Processing: A Clean and Powerful Solution
Ozone (O₃) has emerged as one of the most effective and environmentally friendly tools in modern food processing. Its powerful oxidizing properties make it a superior alternative to traditional chemical sanitizers—killing bacteria, viruses, fungi, and even resistant spores faster and more thoroughly than chlorine, while leaving no harmful chemical residues behind. Because ozone naturally decomposes into oxygen, it offers a sustainable, residue-free approach to food safety and quality preservation.
At the heart of this technology is the three-pass ozone generator, a specialized system designed to deliver ozone in three distinct application stages throughout the food processing environment.
Stage One: Air and Surface Sanitization
The first pass of the three-pass ozone generator targets the processing environment itself. Ozone gas is distributed through production rooms, packaging areas, cold storage facilities, and changing rooms to eliminate airborne pathogens and contaminants. Its gaseous nature allows it to reach every corner and surface—including equipment, utensils, and even workers' garments—without leaving死角. This stage ensures that the entire production space meets the strict hygiene standards required for safe food manufacturing.
Stage Two: Water Treatment and Ingredient Washing
The second pass focuses on water. The three-pass ozone generator produces ozonated water used for processing, washing fruits and vegetables, and sanitizing raw ingredients. Ozone effectively degrades pesticides, removes harmful additives, and eliminates microbial contaminants from produce and seafood. For meat, poultry, and egg processing, ozonated water extends shelf life by significantly reducing bacterial loads. This stage is particularly valuable because ozone-treated water can be recirculated and reused, reducing overall water consumption.
Stage Three: Equipment and Packaging Sanitization
The final pass of the three-pass ozone generator addresses food contact surfaces, processing machinery, and packaging materials. Ozone is applied as a gas or dissolved in water to sanitize conveyor belts, mixers, fillers, and containers before they come into contact with finished products. This step prevents cross-contamination and ensures that the final packaged goods remain safe throughout their shelf life.
Why Choose Ozone?
Ozone technology offers clear advantages over conventional methods. It requires only oxygen or air for production, operates at room temperature without affecting the sensory qualities of food, and decomposes into pure oxygen without leaving toxic byproducts. For food processors committed to HACCP, GMP, and other food safety standards, integrating a three-pass ozone generator into their operations provides a comprehensive, chemical-free solution for air, water, and surface disinfection.
As consumer demand for clean-label, minimally processed foods continues to grow, ozone stands out as a technology that delivers both safety and sustainability—one that modern food processing facilities can rely on from start to finish.
This equipment consists of an ozone generator, ozone water mixing system, UV, ozone concentration detection instrument, flow instrument, ozone leak alarm instrument, and tail gas decomposer PLC control system
The principle is that after the purified water passes through UV to eliminate microbial bacteria, the water pump inhales the raw water and at the same time the ozone is mixed with the water in the water pump using the Venturi method. The ozone water concentration signal is obtained through the sensor in the polarographic electrode and transmitted to the water concentration detector. The ozone generator adjusts ozone production and water concentration according to the signal. When the concentration in water reaches 0.3ppm, ozone operates stably.
The product features two disinfection methods: ultraviolet light and ozone. Ensure water quality. At the same time, an unattended method is adopted to ensure the stability of the product.
