Solution Overview

Problem

In high temperature food processing lines, the need to clean the most contaminated equipment determines overall downtime, leading to unnecessary downtime and cleaning of other equipment, as the entire line must stop for maintenance, even if some equipment is minimally contaminated.

Innovation Solution

Implementing a method where a high temperature food processing line operates with parallel sequences of process elements, allowing one sequence to be cleaned while the other continues operation, by valving off the contaminated sequence for cleaning-in-place procedures, thus reducing overall downtime and optimizing equipment utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the entire processing line stops for cleaning when the most contaminated equipment needs maintenance, then the most contaminated equipment can be cleaned thoroughly, but unnecessary downtime and cleaning of minimally contaminated equipment occurs

Engineering Contradiction:
Improvecleaning completenessVSAvoidprocessing line downtime
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The processing line is divided into multiple parallel sequences (first sequence and second sequence), each capable of independent operation. This segmentation allows one sequence to be cleaned while the other continues processing, eliminating the need to stop the entire line for cleaning of the most contaminated equipment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically switches between parallel sequences based on cleaning needs. When one sequence requires cleaning, the system transitions to using the other sequence for processing, allowing continuous operation while maintaining cleaning schedules for contaminated equipment.

Inventive Principle:
Principle #15Dynamics

2Ease of manufacture

If the processing line stops for cleaning, then cleaning-in-place procedures can be performed on contaminated equipment, but equipment utilization decreases and efficiency is reduced

Engineering Contradiction:
Improvecleaning accessibilityVSAvoidequipment utilization
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

By segmenting the processing line into parallel sequences, the system enables cleaning-in-place procedures on one sequence without affecting the operational status of the other sequence, thus maintaining equipment utilization while providing access for cleaning.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The parallel sequence configuration ensures that useful processing action continues uninterrupted in one sequence while cleaning is performed on the other, eliminating downtime and maintaining continuous productivity.

Inventive Principle:
Principle #20Continuity of useful action

3Reliability

If all equipment is cleaned together during line shutdown, then contamination control is maintained, but unnecessary cleaning of minimally contaminated equipment increases time and resource consumption

Engineering Contradiction:
Improvecontamination controlVSAvoidcleaning time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system applies different treatment to different sequences based on their contamination levels. The most contaminated sequence undergoes cleaning-in-place procedures while less contaminated sequences continue operating, allowing localized cleaning rather than blanket cleaning of all equipment.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

Instead of cleaning all equipment to the same standard, the system performs partial cleaning on sequences that require it most, using cleaning-in-place procedures selectively on the most contaminated sequences while maintaining operation of others.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

A high temperature food treatment method is disclosed wherein by alternatingly operating between a first final heater (13) and second final heater (23) arranged in parallel on a food processing line (30, 40, 50), it is possible to operate a continuous process, yet significantly reducing the overall downtime of the processing line (30, 40, 50), by performing a cleaning in place process on the final heater (13, 23), not currently being used in the high temperature food treatment process, thereby eliminating or significantly reducing the influence on the processing line ( 30, 40, 50) downtime by the process elements and/or processing equipment most easily contaminated.
