The fastgrowing field of cannabis extraction still holds many process inefficiencies that can be easily overcome. A bottleneck often encountered is the packing density, or lack thereof, of cannabis plant material in the extraction vessel. Low packing density leads to a decrease in extraction efficiency and increase in output variability.
Various methods can divide cannabis plant material into parts, or extracts, that contain different chemicals. With cannabis, extraction techniques are often used to isolate specific desirable compounds, and cannabis contains at least 113 cannabinoids, including cannabidiol (CBD) and tetrydrocannabinol (THC). On the other hand, a producer may ...
