1000L HTE Fully Automated Aerosol Extraction System

An industrial-scale aerosol extraction system for very high-volume, room-temperature, residue-free processing of any botanical.

Description

The 1000L Aerosol Extraction System is an industrial-scale platform engineered for very high-volume production. It captures the essential oils, aromatics and oleoresins from virtually any botanical, using inert R134a as the working solvent to extract at room temperature and low pressure, preserving the plant’s full natural profile with no thermal degradation and no solvent residue.

Low PressureOperates at just 2-12 bar for a safer, lower-cost process.

Room TemperatureRuns at 15-45 °C, protecting heat-sensitive compounds.

No ResidueClean, food-grade extracts, ready for direct use.

Fully AutomatedPLC touchscreen control of pressure, temperature and time.

Safe by DesignNon-flammable, non-explosive and non-toxic solvent.

Food-Grade 304 SSPolished stainless steel, with 316 available on request.

How it works

Gentle aerosol extraction

The small, non-polar and inert R134a molecule penetrates the plant tissue and thoroughly extracts the oil-soluble fractions at room temperature, with no thermal degradation and no loss of volatile compounds. The complete aromatic profile is collected intact and easily separated from the solvent.

Because the process does not extract solids or chlorophyll, an additional winterization step is often unnecessary. Extracts are pH-neutral and well suited to pH-sensitive pharmaceutical and cosmetic applications, while the solvent’s low boiling point removes the need for slow, energy-intensive solvent recovery.

Versatility

One system, countless botanicals

The 1000L system extracts, refines and infuses an exceptionally broad range of plant material, from rose and lavender to citrus peel, ginger and culinary spices. The same gentle, room-temperature process can also infuse natural oils back into a base, or layer botanical aromas: add fresh ginger root for a warm, spicy note, citrus peel to lift limonene, or lavender to enrich linalool.

FAQ

Frequently asked questions

Inert, non-flammable R134a. It is non-toxic, non-explosive, and quickly recovered thanks to its low boiling point.

Essential oils, aromatics and oleoresins from virtually any botanical, including flowers, herbs, spices, seeds and citrus peel.

Room temperature (15-45 °C) and low pressure (up to 12 bar), preserving delicate, heat-sensitive compounds.

The 1000 L vessel takes up to about 140 kg (300 lb) of dry botanical material.

380 V three-phase, 40 kW, hardwired. The footprint is 4000 × 3000 × 2200 mm at roughly 6000 kg.

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