Fresh Frozen in the Field
With the advent of new processing techniques in the cannabis industry and new products such as live resin hitting the market more and more processing facilities are desiring fresh, undried bio-mass. During the drying process a considerable amount of terpenes and other aromatics will start evaporating almost immediately after harvest, with most of the evaporation occurring from lighter terpene compounds such as mycrene, limonene, and linalool as soon as the drying begins. These compounds, responsible for the hoppy, citrus, and lavender smells/tastes respectively, are some of the most desirable terpenes to extraction artists but, are among the first to evaporate from the plant and are affected the most by the drying process. Heavier terpenes such as caryophyllene, responsible for that peppery smell, do not evaporate as quickly potentially leading to an unbalanced terpene profile. Processors specializing in live extracts, prefer to maintain the full terpene and aromatic profiles of the plant as much as possible, allowing for a wider range of possibilities during the formulation of their extracts.
When trying to maintain a complete and full bodied terpene profile time and temperature is the enemy. At 70 degrees F. the most volatile terpenes, often some of the most desirable, will start to evaporate immediately with other terpenes starting to evaporate rapidly at 90-100 degrees F. Freezing the bio-mass as quickly as possible has proven to be the best way to maintain the full terpene profile of the plant and an excellent method of storage for processors. However, this presents a particular challenge for cultivators, especially cultivators with large outdoor growing operations. Running freezing equipment and supplying cold storage to rural locations provides its own set of challenges that many cultivators are not prepared to meet.
In addition to the time spent at outdoor temperatures, the time it takes the freshly harvested bud to reach freezing temperatures can be problematic as well. Many cultivators have attempted to address this issue with refrigerator trucks or regular "consumer" grade deep freezes with less than stellar results. While the former often times never gets cold enough to freeze the bio-mass completely, the latter requires a host of deep freezers, miles of extensions cords, and a slew of generators placed out in the field. In both cases, even in the best case scenario, the time it takes to completely freeze the bio-mass takes an inordinate amount of time allowing the ice crystal formed from the water during the freezing process to cause damage to not only the terpenes but cannabinoids as well. Think of these ice crystals as little ninja throwing stars damaging the bio-mass. The top processors in the industry demand that their bio-mass is frozen properly and as quickly as possible. Improper freezing methods can ruin an entire crop.
Oklahoma Supply and Exchange has developed a solution to these challenges to help cultivators supply a quality product that is highly desired by extract artists across the industry. Using a novel approach to horizontal plate freezing, we subject the freshly harvested bio-mass directly to temperatures well below -100 F. allowing us to gauge freezing times in minutes instead of hours. This rapid freezing of the bio-mass causes the ice formation to be more glass-like resulting in less jagged ice crystals, which in turn causes less damage to terpene and cannabinoid profiles. With this novel freezing approach, we can perform this freezing process without the need for extremely expensive and specialized blast freezers or huge commercial diesel generators.
