Meat sterilization equipment Meat products are an indispensable part of the human diet; from the selection of raw meat to the moment it reaches the table, any failure to disinfect even a single step can compromise meat quality and pose risks to human health. Therefore, meat processing plants must rigorously implement disinfection and sterilization measures throughout the supply chain. Why do you often detect a pungent odor near meat processing facilities? That’s a clear sign that disinfection practices have been inadequate. It’s important to recognize that disinfection in meat processing goes beyond routine workshop sanitation—it also encompasses critical air‑environment sterilization.

　　What are the operating procedures for meat‑processing sterilization equipment?

　　The processing procedures employed by meat-processing plants typically comprise the following stages: raw meat—thawing and portioning—marination—stuffing—thermal treatment—sterilization and cooling—labeling, followed by storage. Chlorine dioxide disinfectant plays a crucial role in the inactivation processes at each of these stages.

　　I. Meat-Processing Sterilization Equipment: Disinfection in the Meat Products Manufacturing Process

　　1. When selecting meat as a raw material, fresh meat should be soaked in water for disinfection to remove external pathogens and any blood remaining inside.

　　2. Meat‑processing sterilization equipment is primarily used for frozen meat and is generally categorized into dry, wet, microwave, and steam methods. Conventional natural thawing at 12–15°C results in significant blood loss, takes a long time, and proceeds slowly. Wet thawing involves using running water; it speeds up the process but can lead to nutrient loss, so it is less commonly employed. Microwave and steam thawing impose stringent environmental requirements, necessitate additional disinfection, and are prone to early microbial growth—once contamination occurs, it is difficult to control—so they are rarely used.

　　3. Curing link for meat‑processing sterilization equipment. Curing is generally categorized into three methods: oil‑painting, rolling, and injection. Among these, the roller method is most commonly used. Please note that the stock solution of chlorine dioxide disinfectant employed in this process has a concentration of approximately 20 ppm, with a temperature maintained around 7°C. The curing period lasts about four days, during which the product should be turned over three times, and an appropriate amount of preservative must be added—without exceeding the recommended limit.

　　4. The charging process also requires chlorine dioxide disinfectant.

　　5. Thermal processing in meat‑processing sterilization equipment. This includes boiling, smoking, and hot‑water treatment, all of which serve as cooking‑based disinfection methods. However, thermal processing does not eliminate all pathogens; therefore, the use of chemical disinfectants to achieve complete pathogen removal should not be omitted.

　　6. The sterilization and cooling processes for meat products are divided into aseptic packaging (vacuum extraction) and second‑stage sterilized products (bulk). The packaging bags for these products must be disinfected before use.

　　II. Meat-Processing Sterilization Equipment: Disinfection of Tools in Meat Processing Plants

　　When disinfecting equipment in the meat-processing sterilization workshop with chlorine dioxide disinfectant, the typical concentration is 50–100 ppm. The recommended methods are wiping or spraying; applying the disinfectant as a wet spray helps prevent waste.

　　III. Meat‑processing sterilization equipment: Operator disinfection

　　Workers entering the workshop are generally required to wash and disinfect their hands and feet using a chlorine dioxide disinfectant. During handwashing, operators apply a disinfectant solution with a concentration of 100 ppm and immerse their hands or gloves for 5–6 seconds. For the Zhanghua tank or the Val tank, the disinfectant concentration is typically 100 ppm, and immersion for 10 seconds is sufficient.

4. Air Environment Disinfection in the Meat Processing and Sterilization Equipment Workshop

　　In the meat‑processing and sterilization workshop, both food ingredients and work surfaces not only require disinfection but also need air‑space sanitization. As mentioned above, raw materials in meat processing plants are often piled up in large quantities; if cleaning is delayed, they can quickly develop unpleasant odors and attract flies, raising serious hygiene concerns. The recommended concentration of chlorine dioxide disinfectant for the workshop is typically 100–150 ppm.

　　Environmental disinfection for meat-processing equipment is generally divided into two methods: spray disinfection, at a concentration of 100 ppm, which requires an atomizing device to disperse the solution and deposit harmful particles in the air; and fumigation disinfection, at a concentration of 2,000 ppm. This higher‑concentration method involves placing vaporizers at various locations throughout the facility, where the disinfectant evaporates naturally.

　　In summary, the meat-processing workshop employs chlorine dioxide disinfectant for disinfection purposes, excelling in four key areas: sanitization of processing equipment, air-space disinfection within the meat-processing facility, worker hygiene, and environmental air disinfection. By effectively implementing these four aspects of disinfection, the facility can generally meet the national disinfection standards. Meat sterilization equipment Only then will the work be done properly.
