It seems like one of our major aspirations in the field is coming true... the desire for 1000 bar supercritical CO2 experimental programs and systems to gain popularity. Never have we received so many orders and requests for quotes and systems as we are right now. The ability to do testing on a 1000 bar system has become very attractive to a myriad of markets - health store high concentrates and pure substances, pharmaceuticals, hops, medical marijuana and hemp; and current production clients looking to increase their pressures to investigate extraction results at more extreme conditions. Can they do it faster, is it more efficient, are there high valuables that they are missing out on? Likely, the answer to all of these questions is YES! After years of 1000 bar in house experimental programs, we couldn't be happier... we knew it would catch on! Let us know in the comments section if you have any ideas about what we should extract next! What have you tried to extract at 1000 psi?
Good News! We have successfully purchased Unit 8 at the Westinghouse Plaza Complex, after being a tenant at the site for 20 years. We are cleaning out the space and putting the space up for rent ASAP. Please let us know if you are interested. There is a large open space getting cleaned up and freshly painted, 12,000 sq feet warehouse with high bay, lots of sunlight and small office and mezzanine storage space.
In my opinion, this would be a perfect location for a new craft brewery. CF Tech has experience working with hops extractions, and supplying equipment to hops extract manufacturers. We are good taste testers too! Or, after all this snow and T issues, maybe we should offer the space to the MBTA with our high ceilings, they could move in and build some new Red Line trains! Some of the past tenants of this space have been ambulance storage and mechanics; restaurant appliance and equipment sales; an artist sculptor among others.
Check back soon for photos of the available space!
Is it time for seasonal winter ales yet?!? I think yes, at least here at CF Tech. November brought us many days of SCCO2 hops extraction testing... which, as you can imagine, perfumes the lab and surrounding areas (shop & office), just like your favorite IPA. Hops are always interesting and fun to experiment with around here, as most everyone knows a thing or two about the end product: beer. But it's harder to imagine the small, flagrant, flowers becoming an extract to replace the very things we all see on brew tours, the hops themselves. Even if you are a home brewer, it's probably uncommon for you to be familiar with hops extract, as pelletized hops are abundant and available at your local craft brew supplier.
In this round of hops experiments, we fractionated the extract. We found that the extract starts off as a thick oil, and gets progressively thicker and stickier as the experiment continues. Towards the end of the test, the extract is so sticky and thick that we have to use high heat and a lab spatula to complete the draining of the separation vessel. The feedstock residue is left with no scent after the completion of the test cycle, the extract took it all!
This Thanksgiving, when you are lazing around after your too big meal, sipping on your favorite beer, maybe think to do a little research and find out if your favorite beer company uses hops or hops extract. Let me know in the comments section what you find out!
Two of our current CO2 extraction projects are for the neutracuetical and fragrance industries. Trust me, the fragrance experiments smell much better! Although both used our go-to bench scale R&D system, the experimental programs were night and day. One of the experiments, we ran at high temperatures, 180C and high pressure, 15000psi; the second experimental program started off with high temps and high pressure, but as the testing matrix was expanded, we found, through sensory and visual testing that the preferred operating conditions was a liquid CO2, about 1200psi with the feedstock extraction vessel maintaining temperatures below 105F! CO2 extraction of natural feedstocks has so much variety and potential to extract differing compounds, oils, and value items...only tests will tell!
