Botanical materials are dehydrated, ruptured and comminuted into particles by blades or whips in a fluidized bed. Particles separated from a drying gas are transferred to reduced pressure insulated vessels. Solvents dissolve components of the particles under precise temperature control. Solvents are recirculated and distilled to recover distillates. Distillates are refined by thermal and pressure changes to remove fats, waxes and contaminants and are fractionated to specific essential oils. The essential oils are tested, winterized, filtered, decarboxilated, polished, diluted and discharged into collection vessels. The collected essential oils are pumped through needles into sealed cartridges. The cartridges are tamper-proofed, printed and labeled with batch, botanical source, process, tracking and tracing information and codes.
