In order to scale a cannabis business the shelf-life and quality of the product is paramount. Producers must balance when preserving their product during times of lower supply:
Dry incrementally and lose yields to time, or dry quickly and lose yields to heat and attrition.
There are several techniques with varying efficiency and quality. Drying quickly can burn off valuable Terpenes. In order to understand how to properly cure your cannabis flower lets understand how slow curing is achieved.
Cut down your plant, trim away extra fan leaves. You want to leave more in very dry areas. Cut off as much as you can in humid areas, to help speed up the drying process and prevent mold.
- Dry (Under 30% Relative Humidity) – leave more leaves on your plant while trimming to help slow down the drying process. The more plant matter is left behind, the slower the buds dry.
- Average Humidity – perfect for hanging your cannabis upside down to dry
- Humid (Over 60% Relative Humidity) – separate buds from branches after trimming and place them on a drying rack or mesh to help them dry while avoiding mold.
Dry until outsides of buds feel dry to the touch, and smaller stems snap instead of bend prior to jaring. Remember to regularly inspect jared cannabis.
For perfect control over the drying process humidity and temperature control racks are available for purchase.
Belt dryers primarily use hot airflow pulled from above via vacuum, creating localized air streams and wet spots. Tumbler and belt dryers are trendy but come with a few unfortunate set-backs. While some heat Decarboxylates Cannabinoids, high heat drying destroys volatiles, and consumes huge amounts of energy and space.
One solution is a circular fluid bed-base. It is a relatively compact technology, and becoming a viable option for scaling. As a system, the fluid bed solution functions by intaking and shredding whole plants. The product is suspended over air-streams, increasing the surface area of product exposed to dry air, separating fibrous material, and packaging the extracted biomass into bulk bags. Blending Extracted Sprays are used to homogenize the flavor of smoking products prior to retail. Homogenization is important, unevenly dried hemp means extra degradation, moisture and microbes.
Freeze the cannabis or industrial hemp to -35oC for over 10 hours to preserve the shape and integrity. The frozen product is placed under vacuum pressure in order to facilitate sublimation. Sublimation is a process during which a solid is turned into a gas, skipping the liquid stage in between. Controlled radiant heat is applied during this process, converting the frozen moisture in the product directly into vapor. The vapor is condensed back into a solid and collected in the ice bank. The ice in the ice bank is melted and drained from the ice bank in the form of a hydrosol liquid. Any terpenes lost in the sublimation process can be reclaimed from the hydrosol to be used in other processed terpene infused products.
Supercritical CO2technology delivers unparalleled terpene and cannabinoid Extraction capabilities. To perform this extraction, cannabis must be ground and placed into an extraction vessel. CO2 gas at high temperature and pressure is produced. A pump then forces supercritical CO2 into the extraction vessel where it meets the plant and breaks the trichomes allowing it to dissolve part of the plant material.
Solvent extraction is a process in which compounds are separated based on their relative solubilities. This treatment method involves using solvents with the ability to dissolve desired substance. The process of solvent distillation purifies the substance. Methods for extraction may vary depending on your equipment solvent and extraction goal.
High pressure extraction
High pressure extraction systems achieve high yields quickly. This extraction relies on thermodynamic principles to extract oils without the use of solvents. Biomass under 1.26 kg / s conditions cause the trichome rupture and produce shatter, cannabutter or cannabis oil. The moisture within the flower helps decrease viscosity so the oils can flow better. The majority of lost terpenes and trichomes are captured and returned on batch-by-batch bases. This method retains more terpenes, CBD & THC.
Dedicated To Results
Each of the methods forementioned have advantages for specific applications and cannabis derived products. Techniques used for bulk whole flower without destroying the contents or structure of the flower are constantly improved and are able to dry diverse product evenly. As product development advances new technologies are utilized in the cannabis industry. For cannabis genetic conosures and producers there several ways to preserve and consume cannabis.
Now that cannabis is being grown in volume, the need for large scale processing with controlled and efficient curing protocols is crucial. Significantly improve bulk processing in cannabis.
