The process to freeze dry cannabis has been around for longer than most people realize. The Incas have been performing a natural freeze-drying method involving potatoes since the 13th century. More modern freeze drying began as early as 1890 and further improved in 1909.
Freeze drying, also called lyophilization, is a process that involves freezing the product, lowering the pressure by vacuum and then removing the ice by a process called sublimation. This leaves behind an excellent product closely mimicking the original.
Why Freeze Dry your cannabis?
Curing cannabis normally takes a very long time to complete. In fact, the curing process could take anywhere from three or four weeks to three or four months depending on your method. Freeze drying cannabis at home allows you to go from harvest to completely cured within a matter of just a few days, not months.
The final product can even be superior to that of traditionally cured cannabis. Freeze dried bud looks decidedly more alive than flower that was air dried. In fact, it looks almost exactly like it did when it was harvested. This retention of its beautiful, vibrant colors gives it excellent bag appeal. Freeze drying also preserves all the plant’s oils and terpenes that give your bud that delicious taste and aroma.
The freeze-drying process has another added benefit: the process is so fast and controlled, it almost completely eliminates the growth of mold or mildew. This is essential if you are immune deficient or plan to store your dried bud for long periods of time.
How does it work?
The first step in freeze drying your cannabis at home is to, well, freeze the stuff. Unfortunately, this cannot be done with your normal freezer; it has to be done super-cold and super-fast. This eliminates the possibility of having large ice chunks develop from the water content of your flower. Once frozen solid, we move on to the next stage: Drying
The drying phase involves reducing the pressure by means of a vacuum and gently applying just enough heat until the trapped ice sublimes, or turns directly into its gaseous form. This vapor is attracted to a cold condenser that turns the vapor back into ice. Once about 95% of the water has been removed, its time for the next step: The Final Dry
The final dry is pretty simple. The buds are heated back to room temperature which releases any residual water. Once the final dry is complete, the final product contains less than 5% water. When properly stored, this now freeze-dried cannabis can last for years, even decades.
