Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for extracting value-adding content substances from plant-based content carriers into brew liquids, such as bitter and aromatic substances, face challenges including solid particle flushing, limited process speed, high equipment costs, and inefficient substance transfer, particularly in beer brewing processes.
Innovation Solution
A method involving a dispersion and extraction container where plant-based content substances are introduced into a brew liquid, forming a suspension, followed by gravity-induced phase separation to enrich the brew liquid with value-adding substances, and subsequent recycling of the content carriers, reducing equipment size and improving substance transfer efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If solid plant based aroma bearers are added to brew liquid for cold hopping, then aromatic substances are transferred into the brew liquid, but solid particles are flushed into downstream equipment causing contamination and requiring additional filtration
Solution Approach 1:
The device separates the extraction chamber from the downstream brew liquid flow path using a filter element, segmenting the system into an extraction zone where solids are contained and a flow zone where only liquid passes through. This allows aromatic substance transfer while preventing solid particle carryover to downstream equipment.
Solution Approach 2:
A filter element acts as an intermediary between the extraction chamber containing solid plant material and the downstream brew liquid flow. The filter mediates the interaction by allowing liquid and dissolved aromatic substances to pass while blocking solid particles, thus transferring value without the harmful solid carryover.
2Reliability
If traditional filtration devices are used to separate solid particles from brew liquid, then solid-liquid separation is achieved, but equipment complexity and costs increase
Solution Approach 1:
The filter element serves multiple functions simultaneously: it separates solid particles from liquid, allows dissolved aromatic substances to pass, and prevents solid carryover to downstream equipment. This multi-functionality reduces the need for additional specialized filtration equipment, simplifying the overall system.
Solution Approach 2:
The filter element is designed to be replaceable and reusable. After capturing solid particles during the extraction process, the filter can be easily removed, cleaned or replaced, while the brew liquid containing aromatic substances continues to flow. This reduces the need for complex permanent filtration systems.
3Duration of action of moving object
If large equipment volumes are used for extraction, then sufficient contact time between plant material and brew liquid is achieved, but device size and costs increase
Solution Approach 1:
The extraction chamber concentrates the plant material in a localized region with high surface area to volume ratio. The filter element creates a localized extraction zone where brew liquid flows through and contacts the plant material intensively, achieving sufficient contact time and extraction efficiency without requiring large overall equipment volume.
Solution Approach 2:
The device uses hydraulic flow of brew liquid through the extraction chamber to enhance mass transfer. The flowing liquid creates continuous contact with the plant material on the filter element, improving extraction efficiency and reducing the required contact time and equipment volume compared to static extraction methods.

AI summary
A method for extracting value adding content substances from plant based content substance bearers into a brew liquid by bringing a predetermined amount of the plant based content substance bearers in contact with a predetermined volume of fresh brew liquid in a dispersion and extraction container so that the plant based content substance bearers are at least partially distributed or dissolved in the brew liquid by forming a first suspension and the value adding content substances transition from the plant based content substance bearers into the brew liquid and so that the plant based content substance bearers are separated from the brew liquid by gravity when performing a solid-liquid-separation.
