Fermentation Medium Extraction Chamber for High-Density Microbe Washout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for extracting microorganisms from fermentation media are inefficient, leading to low microorganism density in the eluate, which affects the fertilizing and plant-protecting effectiveness of the resulting fertilizer or plant protection agent.
Innovation Solution
An extraction apparatus and method that involves feeding gas and liquid into the lower portion of an extraction chamber, where they mix and rise through the fermentation medium, effectively dissolving microorganisms, with controlled flow rates and mixing ratios, and discharge the washout liquid through a filter system to achieve high microorganism density.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional washing methods are used to extract microorganisms from fermentation medium, then the extraction process is simple, but the microorganism density in the eluate is low
Solution Approach 1:
The extraction chamber is divided into multiple sections with different functions: a lower portion for receiving and mixing gas-liquid, a middle portion for passage through fermentation medium, and an upper portion for discharge. This segmentation allows each zone to optimize microorganism extraction at different stages, increasing overall microorganism density in the eluate.
Solution Approach 2:
The apparatus utilizes gas flow (air or CO2) and liquid flow in a controlled manner to create bubbling and current through the fermentation medium. The gas-liquid mixture rises through the medium, creating turbulence and enhancing contact between the washing liquid and microorganisms, thereby increasing extraction efficiency and microorganism density.
2Productivity
If gas and liquid are fed from below into the extraction chamber, then microorganism extraction efficiency is improved, but the device complexity increases
Solution Approach 1:
The feed device combines gas feeding and liquid feeding functions into a single integrated system that introduces both phases simultaneously from the lower portion. This merging allows the gas-liquid mixture to be introduced together, creating immediate bubbling and current through the fermentation medium, which enhances extraction efficiency without requiring separate complex feeding systems.
Solution Approach 2:
The system uses pneumatic (gas) and hydraulic (liquid) forces working together to create an effective washing action. The gas flow generates bubbles that rise through the medium while the liquid flow creates current, and their combined effect enhances microorganism detachment and transfer to the washing liquid, improving extraction efficiency.
3Quantity of substance
If the gas-liquid mixture rises through the fermentation medium, then microorganism dissolution is enhanced, but the required flow rates and mixing ratios increase device complexity
Solution Approach 1:
The system allows dynamic adjustment of gas flow rate and liquid flow rate to optimize the gas-liquid mixture composition. The feed device can adapt the mixing ratio and flow rates based on the specific fermentation medium and desired extraction efficiency, enabling optimal microorganism dissolution while managing device complexity through flexible control rather than fixed complex mechanisms.
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 method enhances microorganism density in the washout liquid, improving the fertilizing and plant-protecting efficacy of the eluate by ensuring thorough extraction and controlled conditions for microorganism multiplication.
Implementation Method 1
The at least one gas and the at least one liquid, which are introduced into the extraction chamber from below, pass through the fermentation medium on their way to the upper discharge opening
Implementation Method 2
the microorganisms are particularly effectively and completely dissolved from the fermentation medium
Implementation Method 3
the gas can help to loosen the fermentation medium and can cause the fed liquid to bubble, so that the fed liquid in the extraction chamber comes into contact with the fermentation medium over a large surface cross-section
Implementation Method 4
feeding the gas together with the liquid from below into the extraction chamber can further promote efficient washing out of the fermentation medium
Implementation Method 5
discharge the washout liquid through a filter system to achieve high microorganism density
