Plant Oil Extraction

R5 Industrial Ethanol Extractor
Flexible extraction at industrial quantities.

StarStrike Stainless’s R5 cold ethanol extractor  processes industrial amounts of plant material using cold ethanol or a closely related alcohol.  Our R5 extractor creates a highly concentrated extract tincture that is well-suited for processing into a variety of products such as distilled oils, concentrates, and refined fractions.

The R5 extractor extracts the desired target oils from plant material in very large quantities, and produces a very clean tincture that requires little-to-no clean-up.  Easily process up to 1,000 pounds per shift depending on the source plant material.

Cold and clean. -10 C extraction after 15 minutes

The R5 extractor system includes an industrial chiller that ensures the ethanol solvent stays very cold throughout the extraction process. The R5 extractor’s sight glass shows a -10 C wash after 15 minutes.  Notice how there’s no discernible chlorophyll despite the source material being quite green.

By varying the temperature and wash times, you can achieve efficient extraction for whatever target output you’re seeking.  Whether it is clean tincture for  distillation into fractions, a richer tincture for a variety of target oils, or a robust whole plant oil, the R5 extractor can meet your needs.

Different types of extractors typically prefer the most potent parts of a plant. However, there can be a lot of missed goodness in pre-extracted material (using C02 for instance), as well as value from other less desirable parts of the plant (such as low-grade trim).  Because the R5 extractor can handle very large quantities, and because ethanol is a very efficient solvent, experimentation with less desirable plant parts, or material that has already been extracted, may make fiscal sense.  Why miss out on easily recovered value?

The extractor is mounted on a heavy duty steel cart that can be easily installed and safely operated. All that’s needed to begin extraction is electricity, ethanol, and plant material. Your material may provide much more than you’re getting.
