If only we could get a larger collection cup. We run our 4x20 Duplex without ethanol and fill up both cups overnight. How will we remove the cups with additional and less viscous material?

Yes, we will have a modified collection module that attaches to the bottom of the separator to address that very issue as part of the package. Are you already running with the 12 Ć 4 Ć 10 in extra large collection cup?
Yes, we are using the extra large collection cups. Great to hear something bigger is on the horizon.
Our 4x20L fills up both separator cups during oil runs, and weād sometimes prefer being able to collect all the oil into a single cup to reduce separator cleanup prior to terpene runs (i.e., terpenes in bank 1 and oil and bank 2).
Thanks!

Iāll let you know when it is available as a separate orderable part. Iāll talk to engineering tomorrow and find out more.
Iām honestly more excited for this than the co2 guys.
Now that they are selling equipment using ethanol the co2 salesmen will have to stop telling everyone that ethanol will blow up their lab and kill everyone theyāve ever loved.
Was this product a development of the acquisition of apeks and delta or something previous?

It was already in the works. And I donāt know who at our company would say that to a potential customer that still works here. We donāt talk trash about competitors and recognize there are excellent hydrocarbon and ethanol equipment manufacturers out there that are perfectly safe when used in a C1D1/C1D2 enviornment and that CO2 isnāt the best method for every kind of end product. We have turned people away if they tell us they want to make live resin as their main focus etc or if they want to process large quantities that just arenāt feasible with our system we have recommended ethanol in the past. We try to find what is best for the client and not what we feel like selling them and this was true before the acquisition as well. Was this a conversation you actually had with someone in sales that current works with our company or are you just mudslinging here?

Iāve worked in the extraction sales industry since 2013.
Itās literally an industry joke about the misinformation coming from co2 extractor people. From solvents being poisonous to insanely explosive. They always forget to mention 800 psi operating pressures of SFE and ethanol winterization of co2 oil in this pitch.
Even recently at 2020 shows we had new to the industry people telling us about the āguys at the co2 booth told us butane and ethanol would blow out lab upā so no baseless mudslinging here.
Glad to hear that you arenāt one of those people. All though that would be a interesting convo to have sitting next to a delta ethanol centrifuge if you were. Since you sell both you probably have a pretty realistic view on it. Please educate the other CO2 cultists for the rest of us.
Congrats on the Merger! When is it going up for initial public offering?

Thanks for the clarification. Sales is sales and just like any industry and there are good and bad salespeople anywhere that will say whatever just to make a sale and serve their own self-interests. The cannabis industry is not immune to that truth and neither is any Co2, hydrocarbon, or ethanol extraction company. However, we made great efforts to not be like āsome of those Co2 extraction companiesā that use those scare tactics and be as transparent and informative in general. The amount of information alone available to the general public on our website should give a pretty good idea about how we view extraction as a whole and not a one size fits all type of situation.
Iād be interested to know if that person you spoke with came from our booth at a show or āanother Co2 extraction companyā as there are quite a few out there. Iām sure you will get the chance to have the āwhich method is right for youā conversation standing between a Delta ethanol extractor and an Apeks system at our booths here in the near future when things open back up.
Here is a link to a great webinar from our site that is open to anyone to watch on this very topic from back in November.

āEthanol can not polarize Carbon Dioxide super critical fluid.ā
Ghosh, Jai. (2019). Re: Mixture of solvent. Retrieved from: https://www.researchgate.net/post/Mixture_of_solvent/5d4fb325b93ecd37a25dc612/citation/download.
Co2 is non polar, chlorophyll a.& Chlorophyll b are polar the beauty of Co2 extraction is that under increasing temperature and pressure the polarity of Co2 can be matched to that of the target molecule. A skilled operator can dial in parameters and run times to minimize the extraction of chlorophyll while still maintaining a high level of extraction efficiency. Adding a small percentage of ethanol does not effect the polarity of the extraction, nor does it make it more susceptible to pull chlorophyll when the correct parameters are used. However running at higher temperatures and pressures will raise the polarity of Co2 and can lead to overshooting THC and CBD and pulling chlorophyll at a faster rate resulting in darker oils that require more post processing work.
false again.

Any information or just stopping by to disagree. Do you have any research to the contrary, increasing the temperature and pressure of C02 is the much more dominant factor in changing the polarity of the Co-solvent mix. Have you operated a Co2 system with a 1-5% cosolvent injection stream?
Iām gonna take this guys opinion personallyā¦https://www.researchgate.net/profile/Jai_Ghosh
I think anyone who has ran an ethanol extraction knows it pulls chlorophyll even at low temps.
At 1-5% etoh it wonāt be as prevalent as full ethanol extraction obviously

Balancing the parameters and finding the time that the bulk cannabinoid extraction is at a high level of efficiency ie 80-95% and before it pulls bulk chlorophyll is critical. I donāt think that you can make the same assumptions of a 100% ethanol extraction and apply the same principles to a SCFE with a 1-5% co-solvent concentration. How ethanol interacts with Co2 in low concentrations in a supercritical state is not the same as a straight ethanol extraction. Co2 on its own will pull chlorophyll at low levels that increase with the duration of run time at higher temperatures and pressures. What I am saying is that with a skilled operator you can avoid pulling the vast majority of chlorophyll while maintaining a high level of extraction efficiency and that adding a small percentage of etoh in line that is tunable 1-5% does not create a statistically significant increase in chlorophyll prevalence in the extract when run properly and under the right parameters.

Isnāt the purpose of using a polar cosolvent to increase the polarity of the solvent? It was my understanding that using a cosolvent was to avoid going to the pressures necessary to achieve behavior of a more polar supercritical CO2. That is, you have to run up to 30ksi to be anywhere near as polar as ethanol, but you can get away with 5ksi with a small addition of ethanol/methanol. The downside is that now you have ethanol in your extract.

It is my understanding that the purpose of using a co-solvent regardless of polarity is to increase power of the paired solvent, in this case Co2 in sub/supercritical phases. Polarity can be manipulated by temperature and pressure in a Co2 extractor. The small percentages of etoh injection have little effect on overall SCFE polarity when compared to the variables that can be manipulated with temperature and pressure. Etoh is a much more powerful solvent than co2 and when combined in small percentages you get the advantages of reduced extraction time without saturating the biomass at a percentage that would rip out chlorophyll as is seen in warm ethanol extraction. As far as ethanol being in your extract as a downside, I would disagree and say that the vast majority of Co2 extractors are going straight to winterization anyways and the ethanol partially homogenizes in the extract and lowers itās viscosity thereby making it easier to empty it from the collection cup and requires less etoh added for the winterization step itself. With 1-5% etoh injection the cleaning of the extraction vessels and the separator vessels is made easier, as well reducing extract separator wall adherence and allowing more to oil to flow all the way to the cup. Less work cleaning between runs, and with that reduced labor costs. You still have the ability to adjust from 0-5% ethanol so you can perform terp runs without any ethanol. You can also run a cleaning cycle with no material and a small amount of ethanol injection between runs or at regular intervals.

Have you guys thought about contracting someone to develop SOPs for your new additions? Obviously it can be tuned a lot of ways, but, donāt you think it would be significantly easier to push with the selling point of a list of parameters that can get that 300% increase in efficiency without grabbing too much chlorophyll?
I hate to say it, because I like the range of utility accessible with SCFE and SCFC, but, without some sort of guideline on how to do some of this stuff, itās hard to convince people of its usefulness.
It would be a perfect way stave off naysayers, as well as get the attention of potential buyers that donāt want to buy a machine they have to do months of R&D with just to make decent crude in a reasonable amount of time.

With our current systems we offer basic recommendations for terp runs, subcritical, and supercritical parameters. I would imagine we will offer similar ābaselinesā to work from, but I will have to reach out to engineering for that answer. Iāll check on it and get back with you. I understand that no one wants to buy something that they are going to have to invest an unreasonable amount of time to dial in. Iāll find out and let you know.

If you are not using the cosolvent module than what we have in development would not work for you because it is deigned to work with less viscous extract. We are looking at larger diameter cups for 4x20L systems. Do you have a volume and or weight of extract you are currently yeilding so we can calculate size needed and potentially look at fabricating one for you and othes like you? Thanks.
