Electrolyzed Water Apparatus Segmented Chamber Additive Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrolyzed water-manufacturing apparatuses face challenges in preventing oxidation of additives during electrolysis and enhancing their effectiveness, particularly when using diaphragm-type electrolysis tanks, where electrolytic energy differences between anode and cathode chambers can lead to undesirable pH levels and oxidation of additives like vitamin C or polyphenols.
Innovation Solution
The apparatus electrolyzes water in one chamber before adding an additive and then further electrolyzing it in the other chamber, with a circulation system that allows for controlled flow rates and the use of a free chlorine-removing filter to prevent additive oxidation, enabling the additive to be dissolved and activated in the cathode chamber with higher electrolytic energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If electrolysis is performed by adding vitamin C or polyphenol to electrolysis starting water, then the additive can be dissolved and activated, but oxidation reaction in an anode chamber occurs which destroys the additive
Solution Approach 1:
The electrolysis tank is divided into an anode chamber and a cathode chamber by a diaphragm, separating the electrolysis process into two independent stages. First, electrolysis is performed in the anode chamber to generate electrolyzed water, then the additive is added and further electrolysis is performed in the cathode chamber. This segmentation prevents the additive from being exposed to the oxidizing environment in the anode chamber where oxidation would occur.
Solution Approach 2:
Electrolysis is performed in advance in the anode chamber before the additive is added to the system. The electrolyzed water generated in the first stage is then transferred to the cathode chamber where the additive is introduced and subjected to further electrolysis. This preliminary electrolysis action ensures that the additive is not present during the initial electrolysis phase where oxidation would occur.
2Productivity
If a large amount of electricity is used at the time of electrolysis, then electrolysis efficiency is improved, but anode water shifts to strongly acidic side and cathode water shifts to strongly alkaline side which is dangerous
Solution Approach 1:
The electrolysis process is segmented into two stages occurring in separate chambers. The first electrolysis stage in the anode chamber and the second electrolysis stage in the cathode chamber can be independently controlled with different electricity amounts. This allows optimized electrolysis efficiency in the first stage while controlling pH shifts in the second stage, resolving the contradiction between productivity and safety.
Solution Approach 2:
The electricity amount parameter is changed between the two electrolysis stages. A larger amount of electricity can be applied in the first electrolysis stage in the anode chamber to achieve high productivity, while the electricity amount is controlled in the second stage in the cathode chamber to maintain safe pH levels, thus optimizing both efficiency and safety.

This method prevents oxidation of additives and enhances their effectiveness by allowing controlled electrolysis conditions, resulting in electrolyzed water with improved physical properties and additive activity, such as increased DPPH radical scavenging ability, not achievable with conventional apparatuses.
Implementation Method 1
an electrolyzed water-manufacturing apparatus for electrolyzing electrolysis starting water (water before electrolysis) in one electrolysis chamber partitioned with a diaphragm and then further electrolyzing the water in the other electrolysis chamber

AI summary
An electrolyzed water-manufacturing apparatus comprises: a flow-through-type electrolysis tank, having a pair of electrodes disposed parallel to each other, obtained by forming an anode chamber and a cathode chamber with a diaphragm stretched between the electrodes parallel therewith, and through which water flows through the anode chamber and the cathode chamber sequentially; a electrolysis starting water supply tube connected to the inlet of the anode chamber for supplying electrolysis starting water only to the anode chamber; an electrolyzed water extraction tube connected to the outlet of the cathode chamber for extracting the electrolyzed water; a circulation tube connecting the anode chamber outlet to the cathode chamber inlet; a free chlorine-removing filter disposed in the circulation tube; and a circulation tube formed downstream of the free chlorine-removing filter.
