What is the "yield"?

Yield-by-weight and yield-by-cannabinoid are not the same thing. Once all the cannabinoids have been extracted (often with a 3 or 4 run Cycle), if the raw material is subjected to additional runs more extract may accumulate in the collector - but there won't be any cannabinoids in it because they have already been extracted.

Long after the cannabinoids are extracted, the CO2 (or any solvent for that matter) will continue to dissolve non-cannabinoid compounds, and while these compounds may increase the yield-by-weight, they do not increase the yield-by-cannabinoid. Actually, adding non-cannabinoid extract to cannabinoid extract simply dilutes the cannabinoid content in the overall mix. Furthermore, if you are operating in a jurisdiction that has inventory limits (like Canada), and you are extracting non-cannabinoid compounds, those compounds are effectively reducing the amount of cannabinoid inventory you can carry. Consider that it may be a more efficient use of time and resources to stop extracting once the cannabinoids are removed then changing batches so that time and resources are spent extracting cannabinoids rather than extracting non-cannabinoid compounds.

Extractions are affected by:

a) humidity - moisture will reduce the amount of extract and may make the extract "greenish" in colour as the moisture dissolves chlorophyll. Very dry raw material is best;

b) grind - if the grind is too fine, the raw material will "cake" under pressure, obstructing CO2 contact and transport. On the other hand, if the grind is too coarse, the extractor will not hold much raw material. Because the raw material may consist of various different parts of the plant, experimentation is required;

c) plant section - due to genetics, all parts of the same plant will yield the same "quality" of extract. However, the "quantity" will vary significantly by section;

d) decarboxylation ("decarbing") - a carboxl group in a cannabionoid molecule can decrease its solubility in CO2. Removing the carboxyl group, often by simply applying heat, may increase the solubility and result in higher yield per Cycle. Generally speaking raw material evenly-heated to 240F for 30 minutes will be satisfactory.

There are many articles about decarbing on the Internet.
What is the extractor "batch" capacity?

A "batch" is from 1oz. to 16oz of dry, ground raw material.

Can I increase the capacity? 

Yes. But before you do, you may want to use a capacity calculator to determine how much capacity you really need.

​​Based on the above calculator, a single one of our extractors can address the processing requirements of up to 1600 plants per crop cycle (using trim as feedstock). If you still find that you need something larger, consider that a single 10 litre, fully-configured including coolant source extractor from another supplier would probably cost around US$80,000 - and if it goes down, your entire operation goes down with it. If you purchased five of our extractors (at 2 litres each), the cost would be ~$70,000 (plus another, say $5,000 for freezers, manifolds, tanks, etc.) and the capacity is "distributed" meaning if one extractor goes offline, the others are still producing. Plus, with a distributed system you can run different batches simultaneously and you can easily move systems around if needed. For these reasons, we believe our extractor offers the most flexibility and best value in the market today.​

What is the process?

Typically, a multi-Run Cycle will be set up with the first run(s) being low temperature to extract the light, volatile terpenes. Subsequent runs on the same batch with progressively increased temperature will extract the medium, then heavier compounds. The extract can be collected at any point along the way (separating the terpenes for example) or an entire Cycle can be run and the mixed extract collected at the end. Once your desired process is programmed, you can simply select the Cycle to run the same parameters again - the ability to program/save offers maximum repeatability.

How long does a batch extraction take?

Typically, 3-4 hours per pound.

Do I have to attend to the extractor during the extraction?

Only if you want to retrieve extract between runs - otherwise multiple runs can be programmed to execute automatically and you can leave for extended periods of time.

Can you recycle CO2?

Yes. Using an innovative approach that avoids the use of mechanical pumps, the CO2 can be recaptured/recycled for repeated use. This ability significantly lowers the effective cost of CO2. 

How long is the warranty?

One year, parts replacement only (with the exception of o-rings and seals)
