Water-Ozone ORP System for Carcass Decontamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for microbiological decontamination of animal carcasses, particularly beef, are inadequate in effectively reducing microbial contamination like E. coli 0157 H7, and they often rely on chlorine, which causes environmental damage and poses safety risks.
Innovation Solution
A system that generates a water-ozone solution with an oxidation reduction potential (ORP) of 600-800 mV, using ozone generators and a regulator to adjust water and ozone flow, reducing surface tension and creating a solution that can microbiologically decontaminate carcasses without harming humans or the environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chlorine is used for microbiological decontamination of animal carcasses, then microbial contamination is reduced, but environmental damage increases and safety risks arise
Solution Approach 1:
The patent changes the chemical parameters of the decontamination solution by using ozone (O3) instead of chlorine, creating an oxidizing environment with ORP of 600-800 mV that effectively kills microorganisms while being environmentally benign and safe for human contact
Solution Approach 2:
The patent employs ozone, a strong oxidant, to create an oxidation reduction potential (ORP) of 600-800 mV in the water solution, which provides potent antimicrobial activity against pathogens like E. coli 0157 H7 without the harmful effects of chlorine
2Productivity
If conventional decontamination methods are used, then processing can proceed, but microbial contamination like E. coli 0157 H7 is not effectively reduced
Solution Approach 1:
The patent modifies the water properties by adjusting ORP to 600-800 mV and reducing surface tension to 48-58 millinewtons per meter, creating a solution that maintains processing efficiency while achieving superior microbial contamination reduction of 90% or more
3Reliability
If water surface tension is reduced to improve decontamination, then microbial killing effectiveness increases, but water composition changes
Solution Approach 1:
The patent deliberately changes water composition parameters by reducing surface tension to 48-58 millinewtons per meter through ozone treatment, which enhances wetting and contact with carcass surfaces, thereby improving microbial decontamination effectiveness
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system significantly reduces microbial contamination on carcasses and trimmings, achieving a 90% decrease in E. coli 0157 H7 positive tests and providing a safe, FDA-approved antimicrobial agent that replaces chlorine, minimizing environmental damage.
Implementation Method 1
A system for creating an oxidation reduction potential (ORP) in water with the water being used in the microbiological decontamination of food animal carcasses
Implementation Method 2
The water flowing through the Venturi chamber causes a venturi effect which will draw ozone from the elongated bore in the ozone adjustment housing into the venturi chamber to create a water-ozone solution
Implementation Method 3
The reduced surface tension of the water and ozone solution of this invention enables the solution to microbiologically decontaminate the food animal carcasses by attacking any microorganisms on the carcass
