Cryo Cure CEO Tracee McAfee showcases the benefits of freeze drying in cannabis production.

For decades, freeze drying has been a long discussed, but never perfected, method for drying cannabis before curing. Supported by respected cannabis cultivation authorities such as Ed Rosenthal, freeze drying has been praised for its ability to preserve flower and reduce moisture content to reduce instances of mould and mildew.


But freeze drying has been a far from perfected method – until my partner Greg Baughman and I developed the patent pending Cryo Cure.


Our journey to perfect the cannabis drying and curing process began several years ago after admiring the healthy plants grown by Greg, who is a medical cannabis caregiver in the United States and now serves as President and Head of Cultivation at Cryo Cure. His flower was stunning: the trichomes glistening, the buds vibrant and heavy. I was disheartened to know that they would soon shrink and become unrecognisable shadows of their live plant selves. Was there a way to make it smokable without losing not just its beauty, but the integrity of the buds?

Drying and curing methods

This one-off thought opened a whole new world of drying and curing methodologies, in search of the one that contained the most promise to preserve cannabis flower in as close a state to fresh as possible. We bought a copy of Rosenthal’s Marijuana Grower’s Handbook, in which he extolled the virtues of freeze dried cannabis flower, calling it the best he ever had. Reading that book was our ‘eureka moment’. For someone as seasoned as Ed Rosenthal to endorse the freeze drying method, we knew there had to be something worthwhile to explore.


When we started to research the possibilities, Greg and I found the options to be few, far between, and woefully inadequate to produce consistent results. Many growers were experimenting with freeze drying units built for apple slices, not for the fragile and sensitive cannabis flower. Conditions inside the machines were so harsh the trichomes were snapping off, reducing the overall potency of the flower. The result was too dry, the bud crumbling in my hands. Plus, the machines themselves were not built to hold cannabis flower, squishing the buds in their narrow shelves. We learned the hard way that regular freeze drying units aren’t made for cannabis or hemp. That’s when Greg got to work tinkering with the settings.


After about a year of experimentation, Greg and I were comfortable enough to provide some of our ‘Cryo Cured’ flower to patients under Greg’s care in our home state of Michigan. The feedback was astonishing. Our patients couldn’t believe what they experienced. Not only were the flowers large, light, and a vivid green, but their medicine left them with an energetic feeling, one that I describe as ‘sparkly’ to any Cryo Cure newcomers.


The consumption experience was cough-less and non-irritating; one patient with chronic obstructive pulmonary disease (COPD) was delighted that their medicine no longer caused bouts of painful coughing.


There was one big reason for the energetic high: the Cryo Cure process prevents the degradation of tetrahydrocannabinol (THC) into cannabinol (CBN), which causes the ‘couchlock’ effect. Greg and I have taken to calling Cryo Cured flower ‘live resin flower’, as our freeze drying process preserves freshness at its peak.

Cryo Cure

High THC cannabis and hemp flower dried and cured in a Cryo Cure machine has three hallmark traits:


  • No flower shrinkage. The visual difference is what typically grabs the attention of a grower, processor or consumer for the first time. Cannabis and hemp which has gone through the Cryo Cure process has no flower shrinkage and is vibrant green. The typical bud is at least double the size of flower which has been traditionally dried and cured;
  • No excess moisture. With Cryo Cure, the moisture content of each batch is brought down to between 8% and 12%, with settings that support moisture content as low as 0% to 1%; and
  • Trichome preservation. The potency of Cryo Cure flower is second to none. Lab reports consistently show heightened levels of THC and other cannabinoids and terpenes.

This is because the Cryo Cure process doesn’t break off the precious trichomes, which house cannabis and hemp’s cannabinoid content. The trichomes stay intact and beautiful.


Cryo Cure machines do not allow any part of the flower to go to waste. Greg and I made sure to include terpene harvesting as a setting in our machines, so these valuable compounds can be collected, saved, and added back into other products.


The low moisture settings on Cryo Cure machines increase processing yield as well. Water is the enemy of any kind of hydrocarbon processing such as butane or CO2 extraction. By putting biomass through the Cryo Cure process, the moisture content can make its way to ultra-low points, as low as 1% or an astonishing 0%, resulting in a dramatic increase in extraction yields.


Perhaps the biggest impact, though, is the time saved: Cryo Cure takes only 24 hours from harvest to completion, shaving an average of three weeks off the production timeline. That means product gets to dispensary shelves in record time. It is a game changer at every stage of the cannabis or hemp supply chain.


Currently, Cryo Cure offers two models for cannabis or hemp drying and curing: one which accommodates between 30lb and 60lb of material; and a second which accommodates between 600lb and 1,200lb. Each one is equipped with a built-in deep freezer, which freezes the cannabis to temperatures between -20°F and -30°F (approximately -29°C to -34°C).


As word travels about Cryo Cure, we’ve attracted some impressive endorsements from some of the cannabis industry’s leading figures, including High Times cultivation editor Danny Danko, who was so impressed with Cryo Cured flower that he introduced us to Ed Rosenthal himself. It was a true full circle moment for us to have the man who inspired our journey express support for Cryo Cure. Since then, cannabis advocate Rick Naya has also experienced Cryo Cure and endorsed our process and flower.


Gathering support from such legendary cannabis growers and advocates was not an easy feat, considering how much they have seen, tried and experienced over their decades in the cannabis space. To earn the respect of three of the cannabis industry’s heaviest hitters, you need to come to the table with something that’s better than great – and we have found that with Cryo Cure.

Salutations,

Well i wouldn't miss the vegetal tissue if samples only contained trichome glands, especially those "legal" from an LP. My bet is i got just the right tool for such future testing anyway, when the SQdC is replaced by cooperatives that won't block me at the door for refusal to show credentials other than my gray hairs...

Good day, have fun!! :peace:

Uhhhhh, what?

Curing is a chemical process that requires both proper temps and humidity levels to ripen and mature cannabinoids, increasing flavor, power and effectiveness. I call bullshit. Shortcuts never make things better, just more profitable.

Have you tried it?

...so no freeze dried bud possiblilities for home growers is my takeaway here, damn.,
Freeze Dry is very possible and have done my last 2 harvest with a Harvest Right Medium Size Freeze Dryer. They are made for the process of freeze drying food but works with my buds. They do come out pretty dried and sort of sound/feel like styrofoam peanuts. Throw them in a paper bag in my basement for a few hours (7-8 seems perfect for me) and let them reconstitute some moisture back into your buds. Jar them with or without a moisture pack and never worry about burping again. Here’s a pic of the first batch I ever did of LSD. First pic going in wet and 2nd coming out dry. Neighbour said it was the tastiest weed he ever tried.

and from my last harvest some Amnesia Lemon Kush

Dude that is boss! Does it need to be hooked up to anything else or can you just run it out of the box when it arrives?

To be on the safe side we had to wait a few months before we got to use it. We were on the old fuse box for our electrical panel. We needed to upgrade to the new standard breaker switch panel, with a 20Amp breaker with it to handle the freeze dryer. If you already have those, let it sit for a few hours when you receive the machine to settle things inside and you should be good to go from there.


oh few more thing I forgot to mention @conservative is that the machine need a motorized pump. It comes with a oil pump but the oil needs to be replaced after each use, and so we opted for the oilless pump. It is or at least was about $1300Cnd for the pump alone, but I wouldn’t want the oil pump. Some people had problems finding the oil during the pandemic for their pumps (mom joined some freeze dryer board and had stories to tell) plus you go through Juicerville in Canada and not through Harvest Right in the states. People were wonderful in helping us out and knocked almost $300 off the price if we did direct deposit compare to our credit card for payment, and we did.

I suppose you still need to cure the bud though?

NOPE!

It will be the tastiest shit right out of the machine, but again, paper bag it for a good 6-8 hours and let it reconstitute some moisture back in and jar. Not harvest right video but uses the same process. Their machines have maybe a few more fine tuning options because their machine is made for cannabis, but I believe cost a pretty penny and geared towards more commercial growers

The strain i have barely has any smell or taste.It smells like fresh picked and flash dried hay flowers.I paid 50 for a quarter,and only rolled one out of it...it just sits in a jar ‍

Those machines are not cheap!
