Fermentation Apparatus for Liquid Waste Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for treating organic matter-containing liquid waste, such as watery excrement from livestock, face challenges in efficiently drying large quantities, leading to increased running costs and capital investments.
Innovation Solution
A system comprising a fermentation apparatus that decomposes organic components in liquid waste using microorganisms, producing a fermentation product rich in microorganisms. This product is then discharged onto a target plant, where it naturally ferments and dries, with the filtrate collected and reused to accelerate further fermentation and drying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a vacuum fermentation dryer is used to treat organic matter-containing liquid waste, then the waste can be dehydrated and dried, but the running costs increase and capital investments are required for multiple dryers to treat large amounts of waste
Solution Approach 1:
The system uses the fermentation process itself to generate heat and microorganisms that naturally dry the waste without requiring external energy input for drying. The fermented slurry serves as both the treatment medium and the drying agent, eliminating the need for vacuum fermentation dryers and their associated energy consumption.
Solution Approach 2:
The invention extracts and utilizes the beneficial microorganisms and heat generated during fermentation, separating these useful elements from the waste stream to apply them directly to the drying process, thereby eliminating the need for expensive drying equipment.
2Productivity
If multiple vacuum fermentation dryers are used to treat large amounts of excrement, then the drying capacity increases, but the capital investments increase
Solution Approach 1:
The invention merges the fermentation process with the drying process into a single integrated system. The fermentation tank serves dual purposes: generating microorganisms for treatment and providing the medium for natural drying, thereby eliminating the need for multiple separate dryer units.
Solution Approach 2:
The fermentation tank is designed to perform multiple functions: fermenting the waste, generating heat, producing microorganisms, and serving as the drying chamber. This multi-functionality replaces what would otherwise require multiple specialized devices.
3Ease of manufacture
If fermentation product is discharged onto target plant, then the plant ferments and dries naturally, but the system must handle large volumes of liquid waste
Solution Approach 1:
The system changes the physical parameters of the waste during fermentation, transforming it from a liquid slurry into a semi-solid fermented product with different flow properties. This parameter change allows the fermented material to be discharged and applied effectively without requiring complex handling systems for large volumes.
