They lack some of the customized programming that’s available in other solutions. The same technology is effective for cannabis flowers, but regular commercial freeze dryers aren’t ideal for drying and curing cannabis flowers. Standard commercial freeze dryers are well-suited for drying bubble hash. Using a Commercial Freeze Dryer to Dry Cannabis Flowers? Want to know more about how to use a freeze dryer? Check out our article How Does a Freeze Dryer Work? With freeze drying, you get the dry and the cure at the same time. Production Speed and Consistency - finished in 16 to 24 hours.Īchieve Drying and Curing at the Same Time - traditional drying requires a follow up cure time in sealed jars for at least a couple weeks. Mold growth in the drying room is one of the risks of hang drying flowers in the traditional way.Īesthetic Appeal / No shrinkage - flowers that come out of the freeze dryer retain their bright and robust look and feel, just like when they were alive. Protection - helps to minimize oxidation and eliminates risk of mold/mildew growth while flowers are drying.
Trichome preservation - stabilizes the compounds found in cannabis, allowing for a high-potency and terpene-rich product. Let’s look at some of the advantages of freeze drying cannabis flowers over the traditional hang dry and curing method. But freeze drying flowers can minimize the downside to drying, leveraging the power of sublimation and a vacuum.Īdvantages to Freeze Drying Cannabis Flowers Both are natural processes that will occur in even the most meticulously-controlled drying rooms, as terpenes are exceptionally volatile and oxidation happens by virtue of air exposure. With exposure to the air for a week or more, oxidation and terpene loss also takes place. When cannabis flowers are hung to dry in the traditional way, moisture contained within the plant material evaporates from a liquid into a water vapor over the course of many days. This process is more efficient than evaporation that happens when hash or cannabis flowers are left in the open air to dry. In this way, water is transferred from a solid into a water vapor. Freeze dryers bring material to subzero temperatures and utilize a vacuum to pull moisture from the material as it thaws.
So what is freeze drying? Freeze drying involves removing water moisture through sublimation, not evaporation as with regular drying.
Freeze dryers may currently be associated mostly with bubble hash, but the technology can also be applied to drying and curing cannabis flowers. Freeze drying hash not only speeds up the drying process, it also ensures a consistent and thorough removal of moisture, preventing mold growth and preserving terpenes. In the past few years, using freeze dryers to dry bubble hash has become commonplace for commercial extractors and even in-home hobbyists.
