Ozone-Treated Water Carcass Cleaning System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current carcass cleaning systems fail to effectively remove microbial contamination, particularly from Pseudomonas spp., Campylobacter, Salmonella, E. coli, and Listeria, due to the protective slime produced by Pseudomonas spp., and are costly with minimal reduction in contamination levels, making it difficult to maintain a sterile environment in carcass processing plants.
Innovation Solution
A system comprising a fluid source, ozone generator, radiation source, and disinfectant source, where potable water is treated with ozone and radiation, and optionally used in a spray or bath to clean the carcass, effectively removing bacterial contamination and slime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If potable water is applied to the carcass surface, then the cost of contamination reduction is reduced, but the effectiveness against Pseudomonas spp. and slime is insufficient
Solution Approach 1:
The patent changes the chemical parameters of water by adding ozone (oxidizing agent) and adjusting pH levels to create an acidic environment. This transforms ordinary potable water into a more effective cleaning solution that can penetrate and disrupt the protective slime layer produced by Pseudomonas spp., thereby maintaining cost-effectiveness while improving microbial reduction effectiveness
Solution Approach 2:
The patent introduces ozone as an intermediary substance that mediates between the potable water and the microbial contamination. Ozone acts as a powerful oxidizing agent that breaks down the protective slime barrier, allowing the water to effectively reach and eliminate bacteria such as Campylobacter, Salmonella, E. coli, and Listeria that would otherwise be protected
2Device complexity
If current cleaning technologies are used, then the system is simple, but the protective slime makes it virtually impossible to affect surface contamination
Solution Approach 1:
The patent employs ozone, a strong oxidizing agent, to chemically attack and break down the protective slime layer produced by Pseudomonas spp. The oxidative action of ozone disrupts the slime's protective structure, making the underlying bacterial contamination vulnerable to removal by water, thereby overcoming the barrier without requiring complex mechanical or chemical systems
3Stability of the object's composition
If water is applied at numerous stages, then the carcass surface is kept moist, but microbial spoilage and contamination increase
Solution Approach 1:
The patent implements continuous treatment of water with ozone throughout the cleaning process, ensuring that every application of water maintains its antimicrobial effectiveness. This continuous oxidation process ensures that moisture application does not promote microbial growth, as the ozone-treated water actively prevents contamination while keeping the carcass surface moist
Solution Approach 2:
The patent converts the potentially harmful effect of water (which can promote microbial growth) into a beneficial effect by treating it with ozone. The water that would normally contribute to microbial spoilage is transformed into a protective cleaning agent that actively reduces contamination while maintaining surface moisture, thereby converting a harm into a benefit

AI summary
A carcass cleaning system. Specifically, a system for cleaning an animal carcass using potable water passed through an offline treatment system and the application of this treated water to the surface of the carcass, for example, by running through a bath or by spraying or nebulisation at or onto the surface of the carcass. The invention finds utility in the fields of butchery and slaughtering of animals in the preparation for sale as meat.
