Pasteurizing Device Gaseous Chemical Feed for Container Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pasteurization methods face challenges in managing chemicals within pasteurizing devices, leading to interference, damage to components, and undesirable discoloration of metal containers due to the high concentration and reuse of process liquids.
Innovation Solution
Introducing treatment chemicals into the pasteurizing device's treatment area in a gaseous or aerosolized state using a feed device, allowing for precise control and reducing the need for excess chemicals in the process liquid, thereby minimizing interference and extending maintenance intervals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If chemicals are inserted into the process liquid for container treatment, then container protection from discoloration is improved, but chemical interference and damage to device components worsens
Solution Approach 1:
The patent extracts the container treatment function from the process liquid medium. Instead of adding treatment chemicals to the process liquid, the system uses a separate treatment liquid delivery system that applies treatment chemicals directly to containers in the treatment zone, thereby separating container protection from the pasteurization process liquid
Solution Approach 2:
The patent segments the chemical treatment function from the thermal processing function. The system divides the treatment area into distinct zones: a pasteurization zone using process liquid for heating, and a treatment zone using separate treatment liquid for container protection, allowing independent control of each function
2Loss of energy
If process liquid is reused continuously to improve energy efficiency, then energy consumption is reduced, but chemical concentration and interference worsens
Solution Approach 1:
The patent extracts the treatment chemical delivery from the process liquid circulation system. Treatment chemicals are delivered through a separate treatment liquid system rather than being added to the reused process liquid, allowing the process liquid to be reused without chemical contamination accumulation
Solution Approach 2:
The patent segments the chemical delivery system from the thermal process liquid circulation. The treatment liquid system operates independently with its own delivery mechanism, preventing chemical accumulation in the reused process liquid while maintaining energy efficiency
3Object-affected harmful factors
If treatment chemicals are added to process liquid for container treatment, then container protection is improved, but device complexity and chemical management difficulty worsens
Solution Approach 1:
The patent extracts the treatment chemical delivery function from the complex process liquid management system. By using a separate treatment liquid system with dedicated delivery mechanisms, the patent simplifies chemical management while maintaining container protection effectiveness
