25L Fully Automated Compound Remediation System

A pilot-scale system that scales a validated remediation method to repeatable batches, stripping targeted impurities from extract while protecting the active profile.

Description

The 25L Compound Remediation System scales a validated refining method to pilot batches. It takes a finished botanical extract and selectively strips the constituents you do not want – off-notes, pigments, waxes, residual moisture and trace solvents – while protecting the aromatics and actives, all at room temperature and low pressure. The 25 L vessel bridges bench development and full production, with the throughput and repeatability a pilot line needs.

Process

How remediation works, step by step

1. LoadCharge the extract into the 25 L process vessel.

2. DissolveR134a selectively dissolves the fractions to retain at low pressure.

3. SeparateTargeted impurities are partitioned and removed in a continuous pass.

4. RecoverRefined extract is collected; solvent is recovered for the next run.

How it works

Repeatable refinement at pilot scale

The 25L system applies the same room-temperature, low-pressure selectivity as the bench unit, but at a volume suited to repeatable pilot runs. Controlled R134a dissolves and carries the desired fractions while targeted impurities stay behind, correcting the extract to a defined specification batch after batch.

Because nothing is heated, the refined output keeps its full aromatic and active profile, and the consistent PLC-driven cycle makes results easy to reproduce and document for quality control. Fast solvent recovery keeps turnaround and running costs low as a process moves toward production.

FAQ

Frequently asked questions

Pilot and mid-scale production. It processes roughly 3.5 kg of extract per batch, between the 5L bench unit and the 150L production system.

It is selective: it removes targeted impurities while retaining the aromatics and actives, so the valuable fraction is preserved.

Yes. The PLC controls pressure, temperature and time, so a validated method runs the same way every cycle.

Off-notes, pigments such as chlorophyll, waxes and lipids, residual moisture and trace solvents, depending on how the method is set.

Inert, non-flammable R134a at 15-45 °C, recovered quickly for reuse.

Yes. The solvent is non-flammable, non-explosive and non-toxic, and pressure transducers shut the system down automatically to prevent over-pressurization.
