Problems solved by technology

[0003] However, the steam distillation method also has defects in some aspects: on the one hand, the water vapor will be partially condensed in the distillation tank during the distillation process, which reduces the amount of water vapor and the distillation effect; on the other hand, the temperature of saturated water vapor is 100 °C, if the distillation temperature is too low, some semi-volatile components cannot be completely evaporated, resulting in a low yield of essential oil

Embodiment 1

[0025] Such as figure 1 The shown device for extracting tobacco essential oil by superheated steam distillation includes an extraction tank 9 with a heating device 10 on its outer layer. 11 through the upper port of the hot water steam generating device 12;

[0026] The oil-water separator 5, its upper port communicates with the lower port of the condensation pipe 1 through the condensate outlet 3, wherein the upper part communicates with the upper part of the superheated steam generator 12 through the water outlet 4, and the lower part has an oil outlet 6.

[0027] The outer layer heating device 10 of the extraction tank 9 is a water vapor heating interlayer.

[0028] The outer layer of the condensation pipe 1 is a condensed water interlayer, the condensed water inlet 2 is arranged at the lower part of the condensed water interlayer, and the condensed water outlet 7 is arranged at the upper part.

[0029] The volume of the extraction tank 9 is 50-100L.

[0030] The working...

Embodiment 2

[0032] Using the superheated steam generating device in Example 1 to extract the volatile components in the tobacco, the specific steps are as follows:

[0033] 10kg of tobacco leaves are ground into tobacco powder with a pulverizer, put into a 100L extraction tank, add 1L of 5wt% citric acid aqueous solution (effect: the tobacco leaves contain a large amount of volatile nicotine and other alkaline substances, if extracted, Will affect the quality of volatility, citric acid is combined with alkaline substances to become ionic compounds, less volatile, and denser than water), and then extracted with water vapor in a superheated steam generating device. The condensed water inlet of the condenser pipe is fed with cold water, and the water vapor heating interlayer of the extraction tank is fed with water vapor. After the volatile components extracted by the water vapor are condensed by the condenser pipe, the water vapor becomes liquid water and enters the oil and water together wi...

Embodiment 3

[0035] Use the superheated steam generating device among the embodiment 1 to extract the volatile components in the Radix Glycyrrhizae, concrete steps are as follows:

[0036] Put 5 kg of licorice powder into a 50L extraction tank, then extract it with the water vapor in the superheated steam generating device, the condensed water inlet of the condensation pipe is fed with cold water, and the water vapor heating interlayer of the extraction tank is passed into water vapor, and the water vapor After the extracted volatile components are condensed by the condenser tube, the water vapor turns into liquid water and enters the oil-water separator together with the volatile components. After being separated by the oil-water separator, the water re-enters the superheated steam generator through the water outlet, and the water is obtained. Recycling; the extraction time is 1 to 3 hours. After the extraction is completed, the oily component released from the oil outlet at the lower part...

The invention also discloses a method for extracting the tobacco essence through the superheated steam distillation device.

Description

technical field [0001] The invention belongs to the technical field of tobacco chemistry, and in particular relates to a device and method for extracting tobacco essential oil by superheated steam distillation. Background technique [0002] There are many methods to extract the active ingredients of the volatile components of plants, such as solvent extraction, supercritical fluid extraction, subcritical extraction, steam distillation and so on. Among these methods, supercritical and subcritical extraction methods can be carried out at low temperature without destroying volatile components. However, the equipment of this method is complex and the extraction cost is relatively high. Among many methods, steam distillation is simple, effective, low cost and safe to operate. It is the most commonly used method for plant essential oil extraction. [0003] However, the steam distillation method also has defects in some aspects: on the one hand, the water vapor will be partially ...
