Application of Electrolytic Salt-based Hypochlorous Acid Generator in Food Industry

I. Product Advantages

Adopting high-purity slightly acidic hypochlorous acid generator equipped with perfluorosulfonic acid proton exchange membrane (e.g. Nafion membrane) technology, this equipment is a mainstream high-end solution for producing high-quality and high-stability hypochlorous acid in industrial production. Its core advantages are as follows:

1. Extremely high product purity, fully complying with strict water quality standards for food grade.

2. Greatly improved electrolysis efficiency with lower energy and salt consumption.

3. The pH value can be precisely adjusted within the range of 2-7, and the ORP (Oxidation-Reduction Potential) can be customized as required.

4. Excellent pH control performance: At pH 5.0, the content of hypochlorous acid reaches 99.7% with ultra-high oxidation potential. In neutral water mode at pH 7.0, the effluent salinity can be greatly reduced by dilution with low residual chlorine.

5. Equipped with three cleaning functions including automatic water flushing, self-cleaning and acid cleaning, which extends the service life of the equipment.

6. Designed for low salt consumption suitable for food and cosmetic industries: Salt consumption 300g, power consumption 1.75kW·h, featuring high voltage operation and low residual chlorine.

II. Industry Pain Points

The food industry has entered a new stage featuring stringent safety standards, zero-residue control, cost reduction and efficiency improvement. Traditional disinfection methods have exposed obvious shortcomings and can no longer meet the requirements of modern food production.

The electrolytic salt-based hypochlorous acid generator only uses salt and pure water as raw materials to produce disinfectant on-site. With the strengths of non-toxicity, no residue and wide adaptability, it serves as an eco-friendly alternative to traditional disinfection solutions. It helps food enterprises achieve three major goals: compliant production, quality upgrading and cost optimization.

IV. Working Principle of Hypochlorous Acid Generator

The electrolytic salt-based hypochlorous acid generator applies electrolysis technology. It only uses food-grade salt and purified water as raw materials to generate low-concentration and high-activity hypochlorous acid disinfectant in real time. No chemical additives are used during the whole process, causing no secondary pollution and fully complying with food production safety regulations.

The equipment adopts ion-selective permeable structure. The membrane is fixed with sulfonic acid groups, which can accurately screen ions via electrostatic effect. Only Na⁺ is allowed to pass through directionally, while Cl⁻ and OH⁻ are blocked from transmembrane migration, thus inhibiting side reactions fundamentally.

V. Full-chain Application Scenarios in Food Industry

This equipment is applicable to a full range of food production sectors, including fruit and vegetable processing, meat and aquatic product processing, bakery food, snack food, central kitchen and cold chain warehousing. It covers the whole production process from raw material incoming, production and processing, equipment disinfection, environmental purification, personnel protection to warehousing and fresh-keeping.

1. Raw Material Pre-treatment

Use low-concentration hypochlorous acid water of 50-100ppm to clean and disinfect various ingredients:

1. Fruits and vegetables: Soak or spray the materials to degrade pesticide residues on the surface, kill molds and pathogenic bacteria, slow down oxidative browning, and extend the fresh-keeping period by 2 to 3 days.

2. Meat and aquatic products: Rinse and soak the products to rapidly eliminate harmful bacteria such as Vibrio parahaemolyticus and Salmonella, remove fishy odors, and reduce spoilage loss during cold chain storage.

2. Disinfection of Production Equipment & Tools

Production conveyor belts, material storage containers, cutting tools, chopping boards, sorting tools, pipelines and other equipment and tools are prone to bacterial growth after long-term contact with food materials, which is a major hidden danger of cross-contamination in workshops. Hypochlorous acid water of 100-200ppm can be used with various disinfection modes for comprehensive sterilization.

3. Disinfection of Production Workshop Environment

Bacteria and mold spores tend to accumulate in the air, on floors, walls and corners of production workshops, clean areas and packaging workshops, which will lead to excessive bacteria under suitable temperature and humidity. Combined with atomization spraying devices, hypochlorous acid water can realize regular disinfection of air and workshop environment, supporting simultaneous operation and disinfection without work suspension.

4. Fresh-keeping of Finished Products & Cold Chain Warehousing

Finished food products are vulnerable to secondary pollution, mildew and deterioration during packaging, cold chain warehousing and transportation, which is a main cause of product loss. Before packaging, spray the product surface with low-concentration hypochlorous acid water. It can effectively inhibit bacterial growth and delay deterioration without adding preservatives.

5. Personnel Sanitization

Bacteria carried on the hands and work clothes of production staff are important causes of secondary food pollution. The food-grade hypochlorous acid water produced by the equipment can be used for atomized hand disinfection and work clothes sterilization. It is mild and non-irritating to skin with no residual substances, meeting the regular disinfection demands for staff before and during working hours.
