Peroxide-Catalyzed Cleaning Compositions for Rapid Starch Removal

The patent employs peroxide compounds (such as hydrogen peroxide, sodium percarbonate, or sodium perborate) as strong oxidants to degrade starch and food soils. The peroxide acts as an oxygen donor that oxidizes organic compounds, breaking down starch molecules into simpler substances. This oxidation mechanism provides effective starch removal without requiring highly caustic chemicals, thus reducing chemical complexity while maintaining high productivity.

The patent utilizes temperature as a key parameter to enhance the effectiveness of peroxide-based oxidation. By operating at elevated temperatures (typically 40-70°C), the oxidation reactions proceed more rapidly and efficiently, improving starch removal performance. This parameter change allows the system to achieve high productivity using milder chemicals rather than highly caustic detergents.

The patent incorporates rinsing aids that contain metal complexes (such as manganese or iron complexes) capable of catalyzing peroxide decomposition continuously throughout the rinsing phase. This ensures that the oxidation action continues uninterrupted during the rinse cycle, preventing starch layer formation on freshly cleaned surfaces. The continuous catalytic action eliminates the need for separate post-washing treatments, maintaining reliability while minimizing time loss.

The rinsing aid acts as an intermediary substance that bridges the washing and rinsing phases. It contains metal complexes that mediate the peroxide decomposition reaction, ensuring that protective oxidation continues during the rinse cycle. This intermediary mechanism prevents starch layer buildup without requiring additional alkaline or acid treatments, thus avoiding extra time consumption.

The patent divides the cleaning system into separate functional components: a detergent containing the peroxide compound and a separate rinsing aid containing the metal catalyst. These components are stored separately to maintain stability, as the catalyst would otherwise accelerate peroxide decomposition during storage. During the washing process, the detergent and rinsing aid are applied in sequence, allowing the catalyst to activate peroxide decomposition at the point of use rather than during storage, thus resolving the contradiction between productivity and stability.

The peroxide is provided in advance in the detergent formulation, ready for use. The catalyst is pre-positioned in the rinsing aid. When the rinsing aid is applied after the detergent, the catalyst immediately activates the peroxide decomposition, preparing the oxidizing action for the critical rinsing phase. This preliminary preparation ensures high soil removal efficiency while maintaining storage stability by keeping the catalyst and peroxide separated until needed.
