Down to -75°C
Low Temperature Ethanol Extraction Machine
Cold ethanol extraction systems operating down to -75°C so waxes and chlorophyll stay behind in the biomass.
Cold ethanol extraction chills the solvent hard before it ever touches the biomass. At around -75°C ethanol is still an excellent solvent for cannabinoids and other target actives, but it is a poor solvent for waxes, lipids and chlorophyll, so most of that unwanted load is simply never picked up. The result is a cleaner crude that needs less refining, which is why cold ethanol lines are so common in high-throughput hemp plants.
Who This Equipment Is For
- Hemp processors running high biomass throughput per day
- Producers who want a light-coloured crude with a lower chlorophyll load
- Plants that want extraction and solvent recovery integrated in one line
- Operations moving away from batch maceration towards a repeatable cold process
Problems It Solves
- Dark, chlorophyll-heavy crude that needs aggressive remediation
- Wax pulled into the extract, adding a longer winterization step
- Ethanol consumption that is not recovered efficiently
- Ambient temperature extraction that gives inconsistent colour batch to batch
Key Benefits
Selective at low temperature
At -75°C the ethanol takes the target actives and leaves much of the wax and chlorophyll in the biomass.
Less downstream refining
A cleaner crude means a shorter, cheaper path to a finished oil.
Line integration
Extraction, chilling and solvent recovery are engineered together.
Repeatable batches
Controlled temperature makes colour and profile consistent from run to run.
Specifications For This Line Are Quoted Per Project
Systems are built around your daily biomass throughput, solvent ratio and recovery target. Specifications are quoted per project.
Rather than publishing a model that would not match your process, the specification is written after two questions are answered: what raw material you will process, and what production capacity you need per batch. Machines are built from 0.5L to 200L, and larger capacity is customised on request.
