Abstract

El procedimiento comprende el uso de un solvente conveniente para disolver el aceite en el material de plantas. El material de plantas molido se depositaen un recipiente reactor, y se crea vacío en el recipiente reactor. El solvente líquido se introduce al recipiente reactor y se deja que contacte el material dde plantas por un tiempo suficiente para disolver aceite del material de plantas mientras que la temperatura en el recipiente reactor se mantiene a unnivel que evita desnaturalización de los componentes constituyentes del aceite de plantas y materiales de plantas. Adicionales vapores de solventes seintroducen en el fondo del reactor para provocar mezclado del material de plantas y el solvente y separar materia de partículas finas de las partículasmás pesadas.Vapores de solventes calentados a presión se introducen en la parte superior del recipiente reactor,mientras que la combinación solvente de líquidoy aceite se retira del fondo del recipiente reactor a través defiltros. Para evitar obturación de los filtros en el fondo del recipiente reactor, vapores desolvente a presión se fuerzan a través de los filtros al fondo del recipiente reactor. La combinación de solvente y aceite se transfiere al recipienteseparador, en donde el solvente se evapora y retira para reciclado, mientras que el aceite se retira en un tanque de retención.The procedure comprises the use of a suitable solvent to dissolve the oil in the plant material. The ground plant material is deposited in a reactor vessel, and a vacuum is created in the reactor vessel. The liquid solvent is introduced into the reactor vessel and allowed to contact the plant material for a sufficient time to dissolve oil from the plant material while the temperature in the reactor vessel is maintained at a level that avoids denaturation of the constituent components of the plants and plant materials. Additional solvent vapors are introduced into the bottom of the reactor to cause mixing of plant material and solvent and to separate fine particulate matter from heavier particles. Pressure-heated solvent vapors are introduced into the top of the reactor vessel, while the Solvent combination of liquid and oil is removed from the bottom of the reactor vessel through filters. To avoid clogging of the filters at the bottom of the reactor vessel, pressurized solvent vapors are forced through the filters to the bottom of the reactor vessel. The solvent and oil combination is transferred to the separator container, where the solvent is evaporated and removed for recycling, while the oil is removed in a holding tank.
