Solution Overview

Problem

Existing cheese processing methods face challenges in achieving desired performance characteristics and nutritional qualities, particularly in pasta filata cheeses, due to difficulties in ingredient concentration, activation of functional properties, and significant losses during processing, such as in the pasta filata process where heating in water leads to ingredient removal.

Innovation Solution

A ribbed barrel for an auger made from angular sections of stainless steel, which forms ribs within the interior to prevent cutting, withstand high pressures, and eliminate crevices that can cause contamination, allowing for efficient cheese processing and maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional smooth barrel design is used, then cheese can flow easily, but the cheese loses fat and moisture and suffers structural damage

Engineering Contradiction:
Improvecheese flowVSAvoidfat and moisture loss
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The barrel interior is equipped with ribs that create localized zones of increased friction and mechanical support. These ribs are strategically positioned to provide specific functions: preventing cheese wall adhesion, reducing mechanical cutting, and controlling cheese flow patterns. The local quality change from smooth to ribbed surface allows the cheese to maintain structural integrity while still flowing through the barrel.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The ribs are designed with curved, rounded edges rather than sharp angles. This curvature prevents the ribs from acting as cutting edges that would damage the cheese structure. The rounded geometry allows the cheese to flow over and around the ribs smoothly, reducing mechanical stress and preventing fat and moisture loss while maintaining ease of operation.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Strength

If angular sections are welded to form the barrel, then the structure can withstand high pressures, but crevices and joints may cause contamination

Engineering Contradiction:
Improvepressure resistanceVSAvoidcontamination risk
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The angular sections are designed with curved outer surfaces that form the barrel circumference, while the ribs inside have rounded edges. This curvature eliminates sharp crevices and dead spaces where contamination could occur, making the structure easier to clean while maintaining the strength provided by the angular section construction.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The ribs are integrally formed with the angular barrel sections rather than being separate components. This merging of structures eliminates additional joints and crevices that would increase contamination risk, while the angular sections themselves provide the necessary structural strength to withstand high pressures.

Inventive Principle:
Principle #5Merging (Combining)

3Stability of the object's composition

If ribbed structure is added to prevent cutting, then cheese integrity is maintained, but device complexity increases

Engineering Contradiction:
Improvecheese integrityVSAvoidbarrel structure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The barrel structure is segmented into angular sections that are assembled together to form the complete barrel. The ribs are formed as integral parts of these segments. This segmentation allows for easier manufacturing and assembly while the ribbed structure within each segment provides the necessary protection against cheese cutting and maintains cheese integrity.

Inventive Principle:
Principle #1Segmentation
