Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for decarboxylating cannabinoids, such as those found in industrial hemp and cannabis, often result in thermal degradation products and undesirable chemical modifications due to prolonged heating.
Innovation Solution
A method involving the chemical modification of cannabinoid molecules by providing a composition of cannabinoids with a carboxyl group, contacting it with sufficient energy to convert the native cannabinoid molecule into a carbon dioxide molecule and a modified cannabinoid molecule in a gas phase, and then condensing the modified cannabinoid molecule into a liquid distillate using a heat sink.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If prolonged heating is used for decarboxylation, then complete conversion of cannabinoid carboxylic acids is achieved, but thermal degradation products and undesirable chemical modifications are generated
Solution Approach 1:
The patent applies periodic action by using intermittent heating cycles rather than continuous prolonged heating. The decarboxylation process is performed in repeated cycles of heating and cooling, which allows complete conversion of cannabinoid carboxylic acids while preventing thermal degradation that would occur with continuous heating.
Solution Approach 2:
The patent utilizes phase transitions by heating the cannabinoid composition to vaporize the cannabinoids, then cooling to condense them. This phase change approach enables decarboxylation at lower temperatures for shorter durations, reducing thermal degradation while achieving complete conversion.
2Productivity
If prolonged heating is used for decarboxylation, then complete conversion of cannabinoid carboxylic acids is achieved, but the time required for the process increases
Solution Approach 1:
The patent uses periodic heating cycles that achieve complete decarboxylation faster than continuous heating. By alternating between heating and cooling phases, the process completes conversion in shorter total time while maintaining effectiveness.
Solution Approach 2:
The patent employs phase transitions (vaporization and condensation) to accelerate the decarboxylation process. The vaporization step rapidly converts solid/liquid cannabinoids to gas phase, enabling faster reaction kinetics and shorter processing times compared to conventional heating methods.
3Productivity
If conventional heating methods are used, then decarboxylation is achieved, but energy consumption is high and product quality is reduced
Solution Approach 1:
The patent uses phase transitions to reduce energy consumption. By vaporizing cannabinoids and then condensing them, the process requires less total energy input compared to prolonged heating, while achieving the same decarboxylation efficiency and improving product quality.
Solution Approach 2:
The patent applies periodic heating cycles that consume less energy than continuous heating. The intermittent nature of the heating allows heat to be applied more efficiently, reducing overall energy consumption while maintaining decarboxylation efficiency.
