Solution Overview

Problem

Existing homogenizer dampers in liquid food processing lines face inefficiencies in cleaning and sterilization, leading to suboptimal operation and potential equipment breakdowns due to pressure pulsations.

Innovation Solution

A damper arrangement featuring vessels with air pockets and jackets for sterilization, where the heating media is passed through the jacket rather than directly through the inner chamber, allowing for efficient sterilization and reduced manual cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If hot water is fed through the inner chamber for sterilization, then sterilization can be performed, but time and energy consumption increase

Engineering Contradiction:
Improvesterilization effectivenessVSAvoidcleaning time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent introduces a jacket as an intermediary structure surrounding the inner chamber. Heating media is passed through the jacket to indirectly heat and sterilize the inner chamber contents, rather than directly feeding hot water through the chamber. This intermediary approach reduces the time and energy required for sterilization while maintaining effectiveness.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If hot water is fed through the inner chamber for sterilization, then sterilization can be performed, but energy consumption increases

Engineering Contradiction:
Improvesterilization effectivenessVSAvoidsterilization energy
Core Design Contradiction:
ReliabilityVSUse of energy by stationary object

Solution Approach 1:

The jacket serves as a thermal intermediary that efficiently transfers heat from the heating media to the inner chamber contents. This indirect heating method through the jacket wall reduces energy consumption compared to directly heating water flowing through the chamber, while still achieving complete sterilization.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If manual cleaning is performed, then cleaning can be done, but labor requirements and downtime increase

Engineering Contradiction:
Improvecleaning capabilityVSAvoidoperational downtime
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The damper arrangement is equipped with automatic cleaning capability where cleaning media and heating media can be circulated through the system via valves and pumps. This self-service cleaning system eliminates the need for manual disassembly and cleaning by operators, thereby reducing labor requirements and minimizing operational downtime while maintaining thorough cleaning effectiveness.

Inventive Principle:
Principle #25Self-service
