Special Hypochlorous Acid Generator for Cold Chain Transportation of Lotus Root Sprouts

With the continuous expansion of China's fresh lotus root sprout export scale, long-distance cold chain transportation is prone to pain points such as microbial spoilage, enzymatic browning, water loss, excessive pesticide residues, and failure in inspection and quarantine. Traditional preservation methods have problems including excessive residues, ineffective inhibition, high loss rate, and high compliance risks, which seriously restrict the export quality, customs clearance efficiency and overseas market competitiveness of lotus root sprouts. There is an urgent need for a safe, efficient, internationally recognized full-process preservation and disinfection solution adapted to long-distance cold chains.

Drawbacks of Traditional Preservation Methods for Lotus Root Sprouts

Low temperature only inhibits bacteria but does not kill them, and rapid spoilage occurs once temperature fluctuates; chemical preservatives leave residues and fail to meet export standards; color protection alone cannot solve microbial contamination; the comprehensive loss rate is as high as 30%-50%, making it difficult to meet the requirements of long-distance cold chain transportation and importing country quarantine for lotus root sprouts in overseas markets such as Vietnam.

Product Definition

The special hypochlorous acid generator for cold chain transportation of lotus root sprouts is an on-site liquid-making intelligent device specially developed for post-harvest treatment, cold chain preservation and export customs clearance of fresh lotus root sprouts. It generates slightly acidic hypochlorous acid water that complies with China GB, US FDA and importing country food contact standards through electrolysis technology. The natural sterilizing factor can quickly penetrate the cell membrane of pathogenic bacteria, achieving broad-spectrum disinfection, browning inhibition and pesticide residue degradation. After use, it naturally decomposes into water and trace sodium chloride, with zero residue, no corrosion and no need for secondary rinsing. It is suitable for all scenarios of lotus root sprout post-harvest pre-cooling, soaking sterilization, air-drying packaging and full-process cold chain, building a solid line of defense for preservation and safety of lotus root sprout exports.

No manual adjustment is required, ensuring consistent treatment effect for each batch.

4. Ice Water Synergistic Treatment, Pre-cooling + Sterilization in One Step
Can be directly connected to the ice water mixing system, stably producing liquid at 0-3℃ low temperature without decomposition or efficiency reduction. Synchronously completes lotus root sprout pre-cooling and sterilization preservation, achieving 1+1>2 preservation efficiency and adapting to the pre-treatment process of lotus root sprout cold chain.

5. Full-chain Loss Reduction, Higher Long-term Cost Performance
The cost of self-made hypochlorous acid water is only 0.06 RMB per liter, replacing chemical preservatives; the transportation loss rate of lotus root sprouts drops from 30%-50% to below 5%, and the shelf life is extended by 3-5 days; the equipment is corrosion-free and free of frequent maintenance, greatly reducing the comprehensive export cost.

6. Industrial-grade Stability, Adapted to Large-scale Exports
Core components are anti-corrosion and acid-alkali resistant, capable of 7×24h continuous operation. It is suitable for scenarios of centralized harvesting, batch processing and large-scale export of lotus root sprouts, supporting on-site use in overseas production areas such as Vietnam with stable and reliable performance.
