Problems solved by technology

[0003] The essential part of spices is a volatile component, and the steam distillation method can directly obtain the volatile oil, but the extraction method itself is directly limited, and the steam distillation method can only obtain the fat-soluble volatile oil, but not the water-soluble volatile component, so, get low rate
However, the solvent method, subcritical extraction method, and supercritical extraction method have high yields, but the obtained extracts or absolute oils contain a large amount of non-volatile non-aromagenic components, so the aroma intensity of the products is relatively weak.
More importantly, there are many spices, such as agarwood, sesame, coffee, peanuts, tobacco leaves, etc., which need to be produced at high temperature to produce aroma. Among them, most of the most penetrating top fragrances are lost
[0004] At present, there are relatively innovative retort equipment in China, which can repeatedly retort raw materials to achieve the effect of sufficient material reaction, but the retort environment is single and can only meet one retort condition

Refrigerated liquid condenser 2-3 and liquid N 2 cold trap 2-4; the gas outlet I11 of the raw material bin 1-1 is connected to the air inlet II13 of the air condenser 2-1 through a pipeline, and the liquid N 2 The gas outlet 38 o...

Embodiment 2

[0055]Extracting the agarwood fragrance: open the charging cover 1-4 of the dry distillation extraction kettle 1, load 20 kg of agarwood debris, and cover the charging cover 1-4. Open the passage valve I41, close the intake valve 43, open the exhaust valve 46, close the passage valve II48, start the air pump 3, and vacuum the system. When the vacuum degree no longer rises, turn off the air pump 3 and close the exhaust valve 46. Open channel valve II48. Use the negative pressure of the system to inhale nitrogen from the intake valve 43 to reduce the vacuum degree of the vacuum pressure gauge I42 to 0Mpa. Then close the intake valve 43, start the air pump 3, and the system circulates under nitrogen gas phase and normal pressure conditions. Turn on the condensation system of the multi-stage condensation recovery device ②, turn on the gas preheating device 4, turn on the far-infrared heating switch of the dry distillation extraction kettle 1, and control the temperature at 260°C....

[0062] Tobacco flavor extraction: open the charging cover 1-4 of the dry distillation extraction kettle 1, load 15 kg of tobacco leaf fragments, and cover the charging cover 1-4. Open the passage valve I41, close the intake valve 43, close the exhaust valve 46, open the passage valve II48, start the air pump 3, and the system circulates under the condition of air gas phase and normal pressure. Turn on the condensing system of the multi-stage condensation recovery device 2, turn on the gas preheating device 4, turn on the heating switch of the far-infrared jacket 1-3 of the dry distillation extraction kettle 1, and control the temperature at 360 ° C. Under the action of heating, the moisture and spices of the tobacco leaves are brought into the multi-stage condensation recovery device 2 by the circulating gas and condensed and recovered into the spice collection tanks 2-5. In the first 30 minutes, due to the presence of oxygen, the tobacco leaves are partially burned, and the va...
