Cannabis/Hemp Fractionation with SCF CO2 By extracting with CO2 only, it was possible to effectively separate the dark plant pigments and light volatile oils from the bulk extract (Figure 6). By generating three distinct fractions from a single extraction, extraction facilities are … Continue reading →

Why Is CO2 Better Than Ethanol Extraction for Hemp? Although the cost of Ethanol equipment for larger scale extractions is cheaper than similar scale SFE equipment, the extract that you get from ethanol extraction requires much more post-processing because you … Continue reading →

Why is CO2 Extraction Better than Butane / Solvent Extraction? BHO Basics: Butane hash oil, also known as BHO, is a cannabis-derived oil made using butane as the solvent. In a basic BHO extraction the first step, known as a … Continue reading →

Why is SCF CO2 better than Ethanol Extraction? Ethanol is what is called a “polar” solvent and it will be more hydrotropic, meaning it will want to bind to the water-soluble components of the plant. The result is a less … Continue reading →

Do you make a system larger than 3×1 liters? Yes, Supercritical Fluid Technologies provides extraction systems specifically designed for the Cannabis market with the CannabisSFE 3x5000ml platform and with our NPX SFE Processing Platform configured for Cannabis Extraction you can … Continue reading →

Does the CannabisSFE 3×1 System Come with a PE Engineering Certificate? SFT works with various accredited PE Engineers, who are able to sign off on our design to meet local municipal codes.  Sometimes the local municipality requires a design review, while … Continue reading →

Does THE CannabisSFE system meet ASME Code? The vessels used in our CannabisSFE 3×1 and CannabisSFE 3×5 systems do not require ASME stamps according to ASME regulations, due to their smaller size.  However, both vessel sizes used (1000ml and 5000ml) meet the strict … Continue reading →

What is Our Extraction Cycle Times for the CannabisSFE Family of Extractors?  The cycle time is 20 minutes for the CannabisSFE1x1L and CannabisSFE3x1L systems.  You can figure a 30-minute cycle time for the 3x5L and larger systems.  The functions that must be done are: … Continue reading →

How Does Pressure and Temperature Effect Extraction of Cannabinoids? THC and other cannabinoids are best soluble at 4500-5000 psi.  The CannabisSFE has a significant advantage vs. competitior’s operating pressure, which enhances the solubility of the cannabinoids in the CO2.  Therefore, we can extract very fast. 

What is Cascade Operating Mode? A: You charge all 3 vessels to start the process.  Depending on micron size (200 micron is recommended for maximum extraction efficiency), the vessels can hold the following amounts;    CannabisSFE 3×1 = 400-454 grams CannabisSFE 3×5 = … Continue reading →

What are the benefits of pumping CO2 in a liquid phase rather than a gas phase? The key parameter you desire to optimize for the extraction of natural products is throughput.  Therefore, our family of Supercritical CO2 processing platforms from … Continue reading →
