Solution Overview

Problem

Conventional methods for preparing concentrated broth compositions from animal sources result in non-pumpable products that are difficult to handle and transport, often requiring enzymes or raw extraction steps.

Innovation Solution

A filtration process using specific pore-sized filtration means to separate permeate from retentate, eliminating the need for enzymes and raw extraction, resulting in a pumpable broth with high solids content and extended shelf life.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If concentrated broth composition is prepared from animal sources, then nutrition value and solids content are improved, but pumpability and ease of handling deteriorate

Engineering Contradiction:
Improvesolids contentVSAvoidpumpability
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The patent extracts collagen and gelatin components from the broth composition through controlled cooling and filtration. By removing these gelling agents that cause pumpability issues, the remaining permeate maintains high solids content while achieving pumpable consistency. The filtration step separates the retentate (containing collagen/gelatin) from the permeate (pumpable broth), effectively extracting the problematic components.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent employs filtration means with specific pore sizes to separate components based on their molecular characteristics. The porous filtration medium allows smaller molecules (amino acids, peptides, soluble proteins) to pass through while retaining larger collagen and gelatin structures, thereby producing a pumpable concentrate with high solids content from the permeate.

Inventive Principle:
Principle #31Porous materials

2Ease of operation

If enzymes are added to prepare pumpable broth, then pumpability is improved, but process complexity and manufacturing cost worsen

Engineering Contradiction:
ImprovepumpabilityVSAvoidprocess complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces enzymatic digestion with a mechanical/physical filtration approach. Instead of using enzymes to break down proteins and improve pumpability, the method uses filtration means with specific pore sizes to physically separate collagen and gelatin from the broth. This mechanical separation achieves pumpability without adding enzymatic steps, reducing process complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes physical parameters (temperature, pressure, filtration pore size) to achieve pumpability. By controlling the filtration conditions and selecting appropriate pore sizes, the process transforms the physical state and flow properties of the broth, making it pumpable without requiring enzymatic modification of the protein structure.

Inventive Principle:
Principle #35Parameter changes

3Quantity of substance

If raw extraction step is used to obtain protein composition, then protein content is improved, but processing time and energy consumption worsen

Engineering Contradiction:
Improveprotein contentVSAvoidprocessing time
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

The patent performs preliminary concentration of the broth to high solids content (60-85%) before filtration. This preliminary action reduces the volume and water content that needs to be processed during filtration, thereby decreasing the time and energy required for the extraction step while maintaining high protein content in the final permeate.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements a continuous filtration process where the concentrated broth is continuously passed through the filtration means. This continuous operation maintains efficient protein separation without interruption, reducing total processing time compared to batch extraction methods, while preserving high protein content in the permeate stream.

Inventive Principle:
Principle #20Continuity of useful action
