Abstract

Trichomes, lupulins and other plant parts can be efficiently separated from plant biomass by continuous filtration. In some embodiments plant biomass is collected and combined with water to form a plant biomass mixture. The plant biomass mixture is passed through a filtration device in which the plant biomass mixture is continuously flowed through a filter material. The device includes a cleaning apparatus that cleans the filter material during the process. In some embodiments greater than 90% of the plant parts are collected from the starting plant biomass. The plant parts can be subsequently processed to obtain desired compounds. For example, trichomes can be separated from other plant biomass and subsequently processed to extract one or more cannabinoids or terpenes, such as THC and/or CBD.
