Electrolyzed Water Generator
Sanitation and disinfection in the food production industry is considered the most successful way to preserve safety, since 30% of cases of foodborne illness are due to poor sanitation and disinfection where it occurs. the food.
Currently there is a range of sanitizers and disinfectants used in the food industry, where the most common are chemical agents such as sodium hypochlorite, acetic acid, lactic acid, sodium chlorates, among others.
What Is Electrolyzed Water Generator?
It is a novel antimicrobial agent, which has in its history a variety of applications in Asia, mainly in Japan, and in Russia for many years. Electrolyzed Water Generator, In the United States, EC is just beginning to be recognized, understood, and applied in the food and food service industries.
Furthermore, electrolyzed water is an alternative agent that has been shown to have antimicrobial activity against pathogenic microorganisms. According to a study carried out by the Faculty of Chemistry of the Autonomous University of Querétaro, electrolyzed water was used for the disinfection of tomatoes and avocados, using a comparative framework with sodium hypochlorite, which is a common disinfectant in the industry, where the effectiveness of the EA and NaClO disinfection treatments were similar as there were no significant differences (p <0.05), reducing approximately 2 Log CFU / unit. Salmonella and L. monocytogenes were inoculated in tomato, while NaClO and NEA were able to inactivate more than 2.5 log CFU / unit, after a contact time of 1 min. Electrolyzed Water Generator, On the other hand, In the avocado disinfection treatments, the reductions achieved were <2 Log CFU / unit at the same concentration and time. Current regulations allow the use of EA for fresh meat at levels of 50 ppm and free available chlorine (CLD) for beef and pork and 30 ppm for poultry (SDA-FSIS, 2008).
- Prevents oral infection in procedures when used as a mouthwash.
- It acts as a bactericide and viruside in dental aerosol.
- Prevents secondary infections when used for equipment sterilization.
- Preserves a harmless environment by diffusing it into the environment and using it to disinfect surfaces
How is it produced?
Electrolyzed Water Generator, The process to produce AE combines tap water with small amounts of food grade salt and low levels of electricity in special generators on site to produce two different products that can be described as follows:
In an electrolysis cell, water containing salt is subjected to an electrical current.
The current, together with ion-selective membranes in electrolysis cells, produces two types of water solutions:
Solutions with a high pH of 10.0-11.5 of sodium hydroxide, or of NaOH with low oxidation-reduction potential.
2.3-2.7 low pH solutions of hypochlorous acid infused chlorine gas solution, or HOCl with a high oxidation-reduction potential.
NaOH can be used as a non-corrosive cleaner and mild degreaser.
HOCl is used as a highly effective sanitizer and disinfectant.
Electrolyzed Water Generator, Some of the advantages of this product are: its low toxicity and its nobility towards the environment, its high efficiency of antimicrobial action, its wide application in different industries such as food and hospital, its profitability when producing it at a cost of less than 5 cents per gallon, and its recognition by the EPA, USDA / FDA and CDC (Center for Disease Control).
The main disadvantage of this product is that the solution quickly loses its effectiveness if the water for the EA is not continuously supplied with H +, HOCL, and CL2 by electrolysis; the effectiveness of hypochlorous acid can be reduced in the presence of organic matter, and chlorine gas emissions are a concern.
Method deeply explained:
An anodic electrolyte comprising an aqueous solution with dissolved alkali metal chloride is supplied and circulated from a storage tank (10) of anodic electrolyte, which contains anodic electrolyte, to an anode chamber (2) of a cell of two compartments (1) divided, by a cation exchange membrane (4), into two chambers: an anode chamber (2) that houses an anode (5) and a cathode chamber (3) that houses a cathode (6 ), wherein said cathode (6) is made of porous materials and is arranged to be intimately attached to said cation exchange membrane (4), and wherein the back pressure of said anode chamber (2) is made to be greater than that of said cathode chamber (3), raw water free of alkali metal chloride is supplied to the cathode chamber (3),said raw water free of alkali metal chloride consisting of soft water that is prepared by eliminating the Ca ion and the Mg ion contained in well water and city water, or in ion exchange water that is prepared by additionally eliminating another cation and another anion. , or in pure water that is prepared by additionally eliminating the organic components, and an electrolysis is carried out, with which
Alkali metal chloride-free alkaline electrolyzed water is produced in the cathode chamber (3) and,
chlorine-containing gas is produced in the anode chamber (2) and, after the gas is separated from the anode electrolyte and collected, it is allows said gas to come into contact with a dissolving fluid, free of alkali metal chloride, in which it will dissolve, and
acidic electrolyzed water free of alkali metal chloride is produced.
