Gas-Tight Fermenter With Separated Shell And Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fermenters are cumbersome, costly, and difficult to expand or downsize, with designs that compromise mobility and efficiency due to their size and structural requirements, making them unsuitable for semi-mobile applications.
Innovation Solution
A gas-tight fermenter design featuring a base and a non-supporting shell that separates gas-tight sealing from biomass support, allowing for prefabrication and modular expansion, with a drainage system on the support device side to maintain mobility and facilitate easy installation and resizing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional garage-like fermenter structures are used, then gas-tight sealing and fermentation functionality are achieved, but the fermenter becomes too heavy and cumbersome for mobile or semi-mobile use
Solution Approach 1:
The fermenter is divided into separate functional components: a base unit with drainage system and a removable fermenting chamber with gas-tight walls. This segmentation allows the heavy gas-tight sealing function to be isolated in the chamber while the base remains lighter and movable. The chamber can be detached and transported separately, enabling semi-mobile operation while maintaining reliable gas-tight sealing when assembled.
2Reliability
If conventional construction techniques are used for garage fermenters, then fermentation functionality is achieved, but construction time and costs increase significantly
Solution Approach 1:
The fermenter base unit with drainage system and the fermenting chamber are pre-assembled and tested as complete functional modules before delivery to the installation site. This preliminary assembly ensures that all components are ready for immediate installation, eliminating on-site construction delays and reducing installation time to minimal assembly steps while guaranteeing proper fermentation functionality.
Solution Approach 2:
Multiple functional elements are merged into integrated modules: the base combines support structure, drainage system, and gas-tight sealing interfaces; the chamber integrates fermenting volume, gas collection space, and access mechanisms. This merging reduces the number of separate installation steps and simplifies assembly while ensuring all fermentation functions are present.
3Quantity of substance
If conventional garage fermenter designs are used, then fermentation capacity is achieved, but the system becomes difficult to expand or downsize
Solution Approach 1:
The fermenter system is designed as modular units that can be stacked or arranged in series. Each base unit can support one or more fermenting chambers, and multiple base-chamber assemblies can be connected through standardized interfaces. This segmentation enables flexible configuration where capacity can be increased by adding chambers or units, or decreased by removing them, without affecting the core functionality of existing modules.
4Ease of operation
If drainage systems are embedded in the biomass support area, then liquid removal is achieved, but the base structure is weakened and mobility is compromised
Solution Approach 1:
The drainage system is extracted from the biomass support area and relocated to the opposite side of the base. Liquid removal channels and drainage components are positioned away from the load-bearing regions where biomass weight is applied. This extraction maintains the structural integrity of the base while still achieving effective percolate removal through dedicated drainage pathways that do not compromise the support structure.

AI summary
Fermenter (1), which is designed in gas-tight manner, comprises a base (3) and a liquid-permeable supporting device (4) for supporting and/or receiving the biomass (2) introduced into the fermenter. The fermenter is sealed gas-tight manner by the interaction of at least one base with a non-load bearing shell (5) of the fermenter construction, which is mounted such that the biomass introduced into the fermenter is supported only at the base and the support device. The base has drainage system arranged away from side of the support device, from which the biomass is introduced.
