Automated extraction systems, often resembling modified washing machines, are employed to separate trichomes from cannabis plant material using ice water and agitation. This process produces a concentrated cannabis extract commonly known as bubble hash, due to the bubble-like appearance of the dried resin glands. These systems typically use various sized mesh bags to filter the trichomes based on size and quality, resulting in different grades of hash.
The utilization of these specialized extraction devices offers several advantages over traditional hand-mixing methods. Automation significantly reduces processing time and labor, allowing for larger-scale production. Furthermore, the controlled environment and consistent agitation generally lead to higher yields and a more uniform product quality. This technology represents a significant advancement in cannabis extraction, evolving from the rudimentary methods initially employed.
