Application of Hypochlorous Acid Generator in Egg Cleaning

Hypochlorous acid generators have demonstrated outstanding disinfection effects and operational advantages in egg cleaning, effectively enhancing the hygiene quality of poultry eggs, extending their shelf life, and meeting food safety and environmental protection requirements at the same time. With the continuous improvement of technology, hypochlorous acid cleaning technology is expected to become a standard configuration in the poultry egg processing industry, providing consumers with safer and higher-quality egg products.

At the same time The hypochlorous acid generator produces hypochlorous acid (HClO) solution by electrolyzing dilute brine (NaCl solution), and its effective chlorine concentration can be adjust as need (the concentration commonly used for egg cleaning is 50-100 PPM). Hypochlorous acid is a strong oxidant that can effectively kill bacteria, viruses and other microorganisms. Meanwhile, after decomposition, it only produces water and trace amounts of salt, leaving no harmful residues.

1，Pre-cleaning stage: Use clean water or a low-concentration hypochlorous acid solution (20-30 PPM) to remove obvious dirt from the surface of the eggs
2，Main cleaning stage: Deep cleaning and disinfection are carry out using a 50-80 PPM hypochlorous acid solution

3，Final rinsing: Perform the final rinsing with clean water or a lower concentration hypochlorous acid solution (10-20 PPM)
4，Drying stage: Surface moisture is remove through air drying or baking

1,1 The killing rate of Salmonella can reach over 99.9%

1,2 The removal rate of common foodborne pathogenic bacteria such as Escherichia coli exceeds 99.5%

1,3 The numbers of molds and yeasts have decreased significantly

2,1 The surface cleanliness of eggshells has been improved, and the stains have been reduced by more than 90%

2,2 It does not affect the internal quality of the eggs (indicators such as pH value and Haff units remain stable).

2,3 Extend the shelf life of eggs by 15-30%

3,1 On-site preparation of hypochlorous acid solution is safe and convenient to use

3,2 Compared with traditional disinfectants, it has no pungent smell

3,3 The concentration is controllable and suitable for eggs of different degrees of pollution

Report of a large-scale poultry egg production enterprise after adopting a hypochlorous acid generator cleaning system:

1，The qualified rate of microorganisms on the surface of eggs has increased from 85% to 99.3%
2，The customer complaint rate dropped by 72%

3，After the storage period is extend, the product loss is reduce by 40%
4，The consumption of cleaning water is reduce by approximately 30% (thanks to the recycling of hypochlorous acid).
