Thermal Extraction
Thermal extraction is the process of utilizing heat, rather than a solvent, to be the primary means of separating or isolating a compound from a base material. [1] Beginning with raw material such as plant biomass, or crude plant extract [2], the thermal extraction begins with heat and ends with isolated compounds. These compounds can be drawn off with a stream of air to complete the extraction.
Differentiation between smoking, vaping, and thermal extraction
In comparison to smoking, properly executed thermal extraction does not create combustion. Therefore, combustion byproducts are generally not produced in the thermal extraction process.
Smoking is a method of extracting compounds, but the base material is consumed via combustion in the process. Through the combustion process, in addition to creating the needed heat for extraction, many new compounds including incomplete combustion byproducts are created through various chemical processes. These include, but are not limited to, carcinogens and other toxic compounds such as benzene and carbon monoxide.
Vaping is the use of heat (typically an electrically heated coil) to aerosol-ize a fluid or meltable material.
Key Differences
When a fluid is atomized in a vape, all of the fluid is consumed. There are generally no non-extractable or atomizable constituents. For Thermal Extraction, the process begins with plant biomass. A percentage of the compounds in that biomass are extracted. After extraction, the majority of biomass remains in recognizable form. There typically is cellulose left in the extraction chamber following extraction.
