Abstract

The invention discloses countercurrent distillation essential oil extraction equipment and a countercurrent distillation essential oil extraction process. The essential oil extraction equipment comprises extraction tanks, a condenser and an oil-water separator which are connected in sequence; the number of the extraction tanks is at least three; each extraction tank is connected with a steam source through a steam branch pipeline; a first control valve is arranged on each steam branch pipeline; the steam outlet of each extraction tank is connected with the steam inlet of the condenser througha conveying pipeline; a second control valve is arranged on each conveying pipeline; the steam outlet of each extraction tank is connected with the steam inlet of one adjacent extraction tank througha connecting pipeline; the steam inlet of each extraction tank is connected with the steam outlet of the other adjacent extraction tank through a connecting pipeline; and third control valves are respectively arranged on the connecting pipelines between the extraction tanks which are connected in series front and back. According to the countercurrent distillation essential oil extraction equipmentand the countercurrent distillation essential oil extraction process of the invention, the extraction tanks with the multiple stages of steam inlets and outlets connected in series, heat of directlyinjected steam can be fully utilized through the extraction tanks connected in series, and the steam consumption can be saved by 50% or above.

Description

technical field [0001] The invention relates to the technical field of essential oil extraction, in particular to a countercurrent distillation essential oil extraction equipment and process. Background technique [0002] Evaporation tanks and condensers are widely used in chemical, pharmaceutical, food and other technical fields. The existing distillation essential oil extraction process usually includes evaporation tanks, condensers and oil-water separators. Between the evaporation tanks, condensers and oil-water separators Connected together in series, the liquid to be treated is injected into the evaporation tank, and the solvent in the liquid is volatilized under the action of steam by injecting steam into the bottom of the evaporation tank, and then enters the condenser for condensation to form an oil-water mixture, an oil-water mixture Then enter the oil-water separator to realize oil-water separation. After the liquid treatment in the evaporation tank is completed, i...
