Abstract
A method for phytochemical extraction includes providing a distillation vessel, providing a mixture of solvent and plant extract to the distillation vessel, placing the distillation vessel on a heat source, coupling the distillation vessel with a collector configured to collect condensed solvent, selecting an initial distillation temperature and outputting heat from the heat source at a heat source initial target temperature to heat the distillation vessel to a distillation vessel initial target temperature and boil the mixture in the distillation vessel at the initial distillation temperature and at an initial heat flux. With a vacuum pump, a distillation vessel initial target pressure is set within the distillation vessel.
