Water volatile oil distilling and extracting device and method

Abstract

The invention discloses a water volatile oil distilling and extracting device and method. Compared with conventional distillation extraction methods, both the extraction rate and sensory quality of volatile oil can be enhanced, and the extraction rate can be enhanced by 3-4 times. The device is characterized in that the device includes a round bottom flask, a material steaming pipe and an enclosing and condensation integrated volatile oil extractor; water is put in the flask, and a material is put in the material steaming pipe; water vapor passes through the material and carries volatile oil;condensation is performed in an Allihn condenser from top to bottom; oil and water separation is performed in a separating and collecting pipe under a low temperature environment to perform full cooling; and the precision of a scale pipe reaches 0.01 mL, so that the volume of the volatile oil can be read more accurately. Therefore, the vacancy problem of water volatile oil distilling and extracting devices in laboratories can be solved; the problems of hydrolysis and pyrolysis of volatile oil components caused by long-time soaking of the materials in boiling water can be solved; enclosed condensation and cooling systems can prevent the natural dissipation of the volatile oil during extraction; and accurate scales provide reliable data for the scientific research of the laboratories.

Description

technical field [0001] The invention belongs to the technical field of volatile oil extraction, and in particular relates to a device for extracting volatile oil by distillation over water, and a method for extracting volatile oil by distillation over water using the device. Background technique [0002] Volatile oils, also known as essential oils and aromatic oils, are secondary metabolites of plants, widely present in the whole plant, and distributed unevenly in plant organs such as branches, leaves, bark, trunks, roots, flowers, fruits, and seeds. Under normal circumstances, volatile oils are oily liquids, and a few are solid; volatile oils are volatile, refracting and optically active; easily soluble in organic solvents such as petroleum ether and ethanol, but insoluble in water; most volatile oils are lighter than water, and a few heavier than water. Volatile oil is a complex mixture, generally containing several to dozens or hundreds of different components, most of w...

AI Technical Summary

Problems solved by technology

The water distillation method can reduce the loss of volatile oil in the distillation process, but in the methods reported in the existing literature, there is a lack of a better laboratory device for the extraction of volatile oil by the water distillation method

Therefore, it is necessary to invent a device and method for extracting volatile oil by distillation in water, overcome the disadvantages of distillation in water and solve problems such as incomplete condensation, and improve the extraction efficiency, extraction rate and quality of volatile oil
