Solution Overview

Problem

Conventional moist oral snuff manufacturing processes are lengthy and costly due to the need for extensive aging and fermentation in large barrels, requiring significant time and resources for monitoring and controlling bacterial growth, and there is a desire for more efficient and cost-effective methods to alter the character and nature of tobacco compositions.

Innovation Solution

A method of fermenting tobacco material directly in the final product packaging, eliminating the need for pre-packaging fermentation and allowing fermentation to occur within the container, thereby reducing processing time and costs while maintaining desired flavor and texture.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If conventional barrel fermentation is used, then desired flavor and texture are achieved, but processing time and cost increase significantly

Engineering Contradiction:
Improveflavor and texture qualityVSAvoidprocessing time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent changes the physical parameters of the fermentation environment by transitioning from large barrel fermentation to small pouch fermentation. This involves changing the container size, surface area to volume ratio, and microenvironment conditions to achieve efficient fermentation in a much shorter time while maintaining product quality

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent divides the bulk tobacco material into smaller portions contained within individual pouches. This segmentation allows each pouch to ferment independently and efficiently, reducing the overall processing time compared to fermenting large quantities in a single barrel

Inventive Principle:
Principle #1Segmentation

2Reliability

If large-scale barrel fermentation is used, then fermentation control is achieved, but operational complexity and cost increase

Engineering Contradiction:
Improvefermentation controlVSAvoidoperational complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

By dividing the fermentation process into many small independent pouches, the system simplifies monitoring and control. Each pouch is a self-contained unit that can be processed uniformly, eliminating the need for complex manual intervention required in large barrel fermentation

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pouches are designed to be self-contained fermentation vessels that maintain their own microenvironment. The packaging material itself provides the necessary conditions for fermentation, reducing the need for external monitoring and manual control operations

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If extensive aging is performed, then desired character alteration is achieved, but production efficiency decreases

Engineering Contradiction:
Improvecharacter alterationVSAvoidproduction efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent dramatically reduces the time parameter for character alteration by changing the fermentation conditions in small pouches. The controlled microenvironment and increased surface area to volume ratio accelerate the fermentation process, achieving desired character changes in days rather than months or years

Inventive Principle:
Principle #35Parameter changes

AI summary

A method of preparing a tobacco material for use in a smokeless tobacco product is provided, the method including receiving a tobacco material, wherein the tobacco material has not been subjected to a fermentation process, blending the tobacco material with the final moist snuff product ingredients to form a tobacco composition having a moisture content of at least about 50%, packaging the tobacco composition in a final product packaging such that after a fermentation period of 7 to 28 days within the final product packaging the product is ready for direct sale and consumption.
