Volatile oil extraction device

Abstract

The invention relates to the technical field of essence and perfume extraction, in particular to a volatile oil extraction device. The volatile oil extraction device comprises a distillation mechanism, a volatile oil oil-water separator and a first condensation mechanism, the volatile oil oil-water separator comprises a main pipeline, a steam ingress pipe, an overflow pipe, a flow guide pipe and an oil-water separation pipe, the oil-water separation pipe sequentially comprises an oil storage area and a separation area which are communicated with each other from top to bottom; the inner diameter of the separation area is larger than that of the oil storage area; the bottom of the oil storage area is provided with a circular truncated cone section gradually expanding from top to bottom. A flow guide hole is formed in the bottom of the flow guide pipe in the direction towards the oil-water separation pipe and is directly communicated with the bottom of the circular truncated cone section; the lower edge of the truncated cone section is lower than the overflow point of the overflow pipe; the top of the distillation mechanism is communicated with the main pipeline; the first condensation mechanism is arranged on the top of the diversion pipe. The volatile oil extraction device can still have high oil yield while achieving high oil yield, and is particularly suitable for volatile oil extraction of low-oil-content materials.

Description

technical field [0001] The invention relates to the technical field of essence and fragrance extraction, in particular to a volatile oil extraction device. Background technique [0002] Tobacco-derived aroma substances have the characteristic aroma of tobacco, and can be used in tobacco flavors to enhance the natural aroma that complements the inherent characteristics of tobacco, and cover the local flavor of tobacco leaves in a single area. Volatile oil aroma components are a kind of important tobacco-derived aroma substances, which are usually prepared by continuous dynamic extraction method of steam distillation. . A classic volatile oil extraction device is usually used, which combines a volatile oil oil-water separator with a distillation flask and a condenser tube. After the oil and water vapor is condensed by the condenser tube, the condensate is returned to the volatile oil oil-water separator, and the oil and water are separated to obtain the upper layer of volatil...

AI Technical Summary

Problems solved by technology

[0003] The disadvantages of using the existing volatile oil extraction device for volatile oil extraction are: on the one hand, after the oil-water vapor forms droplets, it rushes into the oil-water interface at a high initial speed from the end of the condensation tube in the form of free fall, resulting in the formation of oil-water mixture. Violent disturbance, part of the oil droplets enter the return pipe with the water flow and return to the distillation bottle, which reduces the oil yield; Inner diameter, although this can increase the oil yield to a certain extent, but it shortens the separation time, affects the separation effect, and reduces the oil yield, resulting in that the two cannot be taken into account at the same time
