Solution Overview
Problem
Current methods for decarboxylation of cannabis are inefficient and variable, leading to incomplete conversion and excessive degradation of cannabinoids, particularly in the production of acidic forms like CBDA and THCA, which are active in cancer treatment and neuroprotection, and result in the formation of CBN as a byproduct.
Innovation Solution
A thin layer decarboxylation method using conductive and radiant heating with precise temperature control to rapidly and predictably convert acidic cannabinoids to their neutral forms, minimizing waste and oxidative degradation, and allowing for the customization of cannabinoid and terpene blends for specific medical effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional decarboxylation methods are used, then decarboxylation of cannabis occurs, but the conversion is incomplete and excessive degradation of cannabinoids occurs
Solution Approach 1:
The patent applies parameter changes by precisely controlling temperature and time parameters during decarboxylation. The method uses controlled temperature ranges (typically 100-150°C) and specific time durations to optimize the conversion of acidic cannabinoids to neutral forms while minimizing degradation to unwanted byproducts like CBN. This precise parameter control resolves the contradiction between achieving complete conversion and preventing excessive degradation.
Solution Approach 2:
The patent employs preliminary action by performing decarboxylation as a controlled preprocessing step before extraction or other processing. By预先 controlling the decarboxylation conditions (temperature, time, atmosphere), the method ensures optimal conversion occurs before subsequent processing steps, preventing both incomplete conversion and excessive degradation that would occur with uncontrolled heating.
2Manufacturing precision
If conventional decarboxylation methods are used, then decarboxylation occurs, but formation of CBN byproduct occurs
Solution Approach 1:
The patent uses parameter changes to control the decarboxylation process within specific temperature and time ranges that favor complete conversion to neutral cannabinoids while minimizing the formation of CBN byproduct. By maintaining temperatures below certain thresholds and controlling exposure time, the method achieves high decarboxylation efficiency without generating excessive harmful byproducts.
Solution Approach 2:
The patent applies the blessing in disguise principle by converting the potentially harmful prolonged heating process into a beneficial controlled decarboxylation treatment. By intentionally controlling the heating parameters, the method transforms what would otherwise be uncontrolled degradation into a precise chemical transformation that maximizes desired product formation while minimizing harmful byproducts.
3Productivity
If rapid decarboxylation is achieved, then conversion speed increases, but oxidative degradation increases
Solution Approach 1:
The patent applies the inert atmosphere principle by conducting decarboxylation in controlled atmospheric conditions (such as nitrogen or reduced oxygen environments). This inert environment allows rapid heating and quick conversion of acidic cannabinoids to neutral forms while preventing oxidative degradation that would occur in the presence of oxygen. The inert atmosphere acts as a protective barrier during the high-temperature conversion process.

AI summary
Dried and or decarboxylated cannabis containing a known composition of cannabinoids is blended with other dried or decarboxylated cannabis of a known composition of cannabinoids and or mixed with other extracts of, isolates of, cannabisor synthetic cannabinoids to achieve a prescribed amount of cannabinoids in the blend. Decarboxylated cannabis is preferentially produced using controlled thin layer decarboxylation. Precision decarboxylation is optionally used to produce a precise pair ratio of acidic to neutral cannabinoid, eg THCA to THC or CBDA to CBD. Further a prescribed or selected terpene profile is mixed and applied to the blend. Once mixed the plant material is suitable for ingestion without further treatment and is dosed appropriately.
