Solution Overview

Problem

Existing methods for inoculating frozen concentrated ferments in the food and dairy industries require batch processing, intermediate thawing, and handling, which increases the risk of contamination and limits production efficiency.

Innovation Solution

A process and equipment for continuous inoculation of frozen concentrated ferments into a liquid using a microwave or water bath thawing device, allowing direct injection into a flow of liquid without interruption, with features like pressurized inoculation chambers, disposable connections, and flow rate regulation to ensure sterility and accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If frozen concentrated ferments are thawed and handled in batch mode using traditional methods, then the ferments can be inoculated into the liquid, but the production process must be interrupted and contamination risk increases

Engineering Contradiction:
Improvecontamination riskVSAvoidproduction rate
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent implements continuous inoculation by connecting the thawing device directly to the fermentation tank via piping, allowing ferments to be continuously transferred and inoculated without batch interruptions. The system maintains continuous flow from thawing through inoculation, eliminating the stop-start nature of traditional batch processing and thereby increasing productivity while maintaining reliability through reduced handling steps.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The patent merges the thawing device and inoculation system into a single integrated unit where thawed ferments are directly inoculated into the fermentation tank through connected piping. This consolidation eliminates intermediate transfer steps and handling operations, reducing contamination risk while maintaining continuous operation for increased production efficiency.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If intermediate thawing containers are used for frozen concentrated ferments, then the ferments can be thawed, but contamination risk increases due to additional handling

Engineering Contradiction:
Improvethawing capabilityVSAvoidcontamination risk
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent extracts the thawing function and integrates it directly into the inoculation system through piping connections. Instead of using separate intermediate containers for thawing, the system thaws ferments in-place within the closed piping network and directly inoculates them into the fermentation tank, eliminating the need for intermediate handling and reducing contamination risk while maintaining operational ease.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent uses piping as an intermediary medium to transfer thawed ferments directly from the thawing device to the fermentation tank without requiring intermediate containers. This closed-system intermediary eliminates exposure to the environment during transfer, reducing contamination risk while maintaining the ability to easily thaw and inoculate ferments.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If frozen concentrated ferments are added directly to the fermentation tank, then continuous inoculation is achieved, but the ferments must be in liquid form requiring prior thawing

Engineering Contradiction:
Improvecontinuous productionVSAvoidthawing equipment
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent employs a multi-functional integrated device that combines thawing, holding, and inoculation functions in a single system. The device can thaw frozen ferments, maintain them in a held state, and directly inoculate them into the fermentation tank through integrated piping, eliminating the need for separate equipment for each function and reducing overall system complexity while enabling continuous production.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent performs preliminary thawing of frozen ferments within the integrated device before inoculation. The thawing function is built into the system and activates ferments in advance of their use in the fermentation tank, ensuring they are in liquid form ready for continuous inoculation without requiring separate pre-processing equipment.

Inventive Principle:
Principle #10Preliminary action
