Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing fermented soybean meal are inefficient in producing separate or combined products for monogastric and ruminant animals, requiring separate facilities and facing challenges such as high contamination risk and scalability issues due to oxygen-dependent aerobic fermentation processes.
Innovation Solution
An apparatus that includes a solid-liquid separating part, lactic acid bacteria culturing part, and solid substrate fermenting part to selectively produce fermented soybean meal for monogastric and ruminant animals by culturing lactic acid bacteria in soybean meal extracts and using them as starters, with a drier for temperature-controlled drying to produce high-protein fermented soybean meal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If aerobic solid substrate fermentation method is used, then fermentation efficiency is improved, but contamination possibility increases and facility investment is required
Solution Approach 1:
The patent changes the fermentation parameter from aerobic to anaerobic conditions, using lactic acid bacteria instead of mold or aerobic bacteria. This parameter change maintains fermentation efficiency while eliminating contamination risks associated with aerobic processes, as lactic acid bacteria create an anaerobic environment that prevents unwanted microbial growth
Solution Approach 2:
The patent creates an anaerobic (inert) environment for fermentation by using lactic acid bacteria that consume oxygen during fermentation. This inert atmosphere prevents contamination by aerobic microorganisms while maintaining high fermentation efficiency, resolving the contradiction between productivity and contamination risk
2Reliability
If aerobic solid substrate fermentation method is used, then fermentation quality is improved, but facility investment and scalability are worsened
Solution Approach 1:
The patent extracts the oxygen requirement from the fermentation process by using anaerobic lactic acid bacteria instead of aerobic microorganisms. This eliminates the need for complex oxygen supply facilities and fermentors, maintaining fermentation quality while reducing facility investment and improving scalability
Solution Approach 2:
The lactic acid bacteria perform self-fermentation without requiring external oxygen supply facilities. The bacteria create their own anaerobic environment and conduct fermentation autonomously, eliminating the need for complex aerobic fermentation equipment while maintaining high fermentation quality
3Adaptability or versatility
If separate facilities are used for monogastric and ruminant animals, then product specificity is improved, but device complexity increases
Solution Approach 1:
The patent makes the fermentation facility universal by using lactic acid bacteria that can produce fermented soybean meal suitable for both monogastric and ruminant animals in the same facility. The process accommodates different animal requirements through parameter control rather than physical separation, maintaining product specificity while reducing device complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus enables the production of fermented soybean meal with high crude protein content suitable for both monogastric and ruminant animals, minimizing contamination and facilitating scalable production by using anaerobic lactic acid bacteria fermentation and controlled drying processes.
Implementation Method 1
Lactic acid bacteria that is anaerobic bacteria converts indigestible oligosaccharide that is one of the representative anti-nutritional factors of soybean meal into a beneficial substance, such as lactic acid
Implementation Method 2
the solid substrate fermentation method using anaerobic bacteria is counted as an alternative
Implementation Method 3
a drier, which dries the primary solid substrate fermented soybean meal supplied from the solid substrate fermenting part to produce secondary solid substrate fermented soybean meal
