Problems solved by technology

[0006] 1. Patent document CN1431285 introduces a volatile oil extraction separator, which is made of glass and is only suitable for laboratory production
[0007] 2. Patent document CN2686690Y discloses a simple separation extractor for volatile oil of traditional Chinese medicine. After the extractor is condensed, the oil-water mixture has a free fall motion, which causes further mixing of oil and water and reduces the efficiency of oil-water separation.
[0008] 3. Patent document ZL20062009819.5 introduces a steam-electric dual-purpose aromatic oil distillation equipment, which adds an electric heating device to realize steam-electric dual-use, but cannot distill active ingredients at the same time
[0009] 4. Patent document ZL200720084936.2 introduces a portable integrated aromatic oil distillation device, but the device is also too heavy, and the top cover alone needs to be moved by a manual hoist, and the steam generator and steam cylinder are integrated
[0010] 5. Patent document CN101250104 introduces the method of ethanol extraction and adsorption of impurities and shikimic acid respectively with different resins. This method uses ethanol extraction, which increases the cost of solvent recovery
[0011] 6. [Title] Development and application of high-yield continuous aromatic oil distillation method and equipment [Author] Li Anping Liu Jianan [Organization] Central South Forestry College [Title] Forestry Science and Technology Development. 1999 (3).-34-35 [Abstract] The The aroma oil distiller can carry out continuous distillation by sending steam through the boiler, and use the elevator to feed the material. Although this equipment improves the processing capacity, it cannot distill the active ingredients at the same time

Embodiment 1

[0043] like figure 1 Shown, a kind of star anise shikimic acid leaching and fennel oil distillation dual-purpose device is provided with distillation tank or extraction tank 1, material basket 2, basket cover 3; The connecting port end is respectively provided with a dislocated multi-layer can opening sealing ring 7 and a material basket sealing ring 6 , and the basket cover 3 is provided with a basket cover sealing ring 5 that matches the ring groove above the material basket sealing ring 6 .

[0044] Further, the above-mentioned ring groove above the basket seal ring 6 is provided with more than 2 rings of water storage seals and / or rubber seal rings, and the height of the annular baffles of each ring groove above the basket seal ring 6 is from inside to From low to high outside.

[0045] Further, an annular baffle cover is provided below the above-mentioned material basket sealing ring 6, and the annular baffle cover is matched with the annular groove of the tank mouth sea...

Embodiment 2

[0052] A kind of star anise shikimic acid leaching to the application of fennel oil distillation dual-purpose device, technological operation is as follows:

[0053] (1) Close the drain valve and the inlet steam / liquid valve at the bottom of the distillation / extraction tank, place a rubber sealing ring in the sealing ring of the tank mouth of the distillation / extraction tank, and then fill the tank mouth sealing ring with water;

[0054] (2) Turn off the switch of the bottom plate of the material basket, directly add the whole star anise fruit or whole dried fruit into the material basket, put a pressing plate on the raw material surface, and then hoist the material basket into the still / extraction tank Inside;

[0055] (3) Place a rubber sealing ring in the sealing ring of the material basket, and then fill the sealing ring of the material basket with water;

[0056] (4) Connect the quick connecting pipe of the liquid pump liquid outlet and the liquid inlet pipe of the exter...

Embodiment 3

[0062] Add 510kg of whole star anise fruit directly into the basket, add 3000kg of water to the still / extraction tank; cover the basket, connect the lid liquid valve, and close the lid liquid valve, inner liquid valve and outer liquid valve , open the vapor-liquid valve and the steam valve, after the temperature rises to 95 °C, start the liquid pump, and force the solution to circulate at 95 °C for 1 hour; separate anise oil and shikimic acid, and recover the water for the next batch of anise oil and shikimic acid. Extract water. After testing, star anise shikimic acid content is 2.7%, fennel oil content is 3.2%, distillation obtains fennel oil 14.72kg, shikimic acid solution 2468kg, shikimic acid content is 0.46% and calculates shikimic acid recovery rate 82.6%, fennel oil recovery rate was 90.2%.
