Some consumers want the highest tetrahydrocannabinol content they can get their hands on. In states with legalized cannabis, there’s a massive demand for concentrates and cannabis vaping products. However, what does all this mean in terms of extraction? Freeze drying also allows cannabis to enter the market more quickly. Freezing cannabis in general helps protect against temperature-related chemical degradation. In simple terms, it makes cannabis buds look a lot prettier for consumers. Through some trial and error, DeLong combined low pressures and low temperatures (down to -85☏) for equipment that reduces the dry time to about 24 hours for up to 1,100 pounds.įreeze dried cannabis maintains high cannabinoid and terpene content in addition to keeping its initial taste, color, and shape. When cannabis was medically legalized in Arizona where DeLong’s company is located, they set out to produce the best-looking flowers for packaging. Recently, freeze drying cannabis for commercial use was further developed by Rich DeLong, founder and operator of Botanique Preservation Equipment. ![]() Rosenthal recommended commercial freezers for scaled operations and large paper bags to slow the evaporation for curing. This is possible since water sublimates from the frozen flower, turning directly from ice to water vapor without going through the liquid state. He analyzed that by using the frost-free section of a home freezer, one can dry cannabis within 10 to 20 days. Freeze drying cannabis was made notable by Ed Rosenthal, author of the Marijuana Grower’s Handbook.
