Molecular Sieve Drying System for Terpene Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional drying methods for plant materials, such as cannabis, result in the undesirable loss of volatile terpenes, altering the terpene profile and affecting the smell, flavor, and medical/recreational effects of the dried product.
Innovation Solution
A system and method utilizing an airtight container with molecular sieves and a circulation device to dry plant materials, where water vapor is adsorbed by the sieves, preventing terpene loss, and maintaining the original terpene profile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional air drying or freeze drying methods are used to remove water from plant material, then water removal efficiency is improved, but terpene loss increases
Solution Approach 1:
The patent extracts and removes water vapor from the drying environment using molecular sieves, separating the water removal function from the terpene retention requirement. The molecular sieves selectively adsorb water molecules while leaving terpenes in the plant material, thus achieving efficient drying without terpene loss.
Solution Approach 2:
Molecular sieves act as an intermediary substance between the plant material and the drying air. They selectively bind water molecules through adsorption while allowing terpenes to pass through unaffected, mediating the drying process to protect terpenes from evaporation loss.
2Loss of substance
If temperature-controlled drying is used to maintain plant material quality, then terpene retention is improved, but drying time increases
Solution Approach 1:
The patent replaces thermal energy-based drying with a chemical adsorption-based drying system. Instead of using heat to evaporate water, molecular sieves chemically adsorb water molecules from the plant material environment, enabling rapid drying at low temperatures that preserve terpenes.
Solution Approach 2:
The invention changes the drying mechanism from thermal evaporation to adsorption. By using molecular sieves with specific pore structures and adsorption properties, the system achieves rapid moisture removal at controlled temperatures, optimizing both drying speed and terpene retention.
