[0030] like Figure 1As shown, the utility model provides a multifunctional extraction and concentration system, including a control cabinet 11, an extraction / concentration device, a defoaming separation device and an essential oil separation device, and the control cabinet 11 is electrically connected to the extraction / concentration device, the defoaming separation device and the essential oil separation device. The extraction / concentration device includes a water tank 1, a circulation pump 2 and an extraction tank 3, the defoaming separation device includes a defoaming separator 4 and a condenser 5, and the essential oil separation device includes an essential oil separator 6, a pure water collection tank 7, a vacuum pump 8 and a circulating water tank 9.

[0031] The extraction / concentration device includes a water tank 1, a circulation pump 2 and an extraction tank 3. Materials are added to the extraction tank 3 in advance. A liquid level scale is provided inside the water tank 1. The liquid level scale monitors the water level inside the water tank 1. The water tank 1 is replenished with water in time, so the material-liquid ratio can be guaranteed. The lower end of the water tank 1 is connected to the inlet of the circulation pump 2. The outlet of the circulation pump 2 is connected to the feeding port 31 of the extraction tank 3 through a heat exchanger. The water in the water tank 1 enters the extraction tank 3 through the circulation pump 2. When passing through the heat exchanger, the water is temperature-treated according to the high, medium and low temperature requirements of the production requirements. The nozzle of the feeding port 31 is set as a scattering head so that the incoming water can fully and evenly soak the materials in the extraction tank 3. A material outlet 34 is provided below the extraction tank 3. The material outlet 34 can circulate the extraction / concentration water soaked with the material, discharge it into the circulation pump 2 through a pipeline, and enter the extraction tank 3 again through the feeding port 31 after passing through the circulation pump 2.

[0032] When vacuum concentration is performed, since plant materials will produce tannins and foam during production, the exhaust outlet 33 above the extraction tank 3 is opened to discharge the tannins and foam from the inside of the extraction tank 3 and enter the defoaming separator 4. The gas in the defoaming separator 4 and the liquid brought out by the gas are separated, and the liquid is discharged from the lower outlet 42. After passing through the hot water tank 10, it re-enters the extraction tank 3 from the circulation inlet 32. The gas is discharged through the upper outlet 41 and enters the condenser 5. The condenser 5 is equipped with cooling water. The cooling water enters from the bottom of the condenser 5 and is discharged from the top of the condenser 5. Therefore, the gas forms essential oils, pure water and other substances after cooling, and enters the essential oil separator 6 for precipitation. The essential oil separator 6 is provided with a pipe connected to the vacuum pump 8 on the side. The vacuum pump 8 performs vacuum treatment on the entire system. According to production requirements, the system can produce a high-pressure or low-pressure environment. The vacuum pump 8 is connected to a circulating water tank 9 for cooling the vacuum pump 8.

[0033] Due to the different densities of the substances in the essential oil separator 6, the oil phase floats above the water phase, and the two enter the separation tank 12 for separation. Due to the height difference between the two separation tanks 12, the oil phase is retained in the separation tank 12, and the oil in the plants is condensed, so that the essential oil and pure water are classified and recovered, thereby improving the utilization rate of the materials; the pure water is discharged into the pure water collection tank 7 and discharged through the drain valve 71 below.

[0034] Example 1

[0035] During conventional concentration / extraction, production parameters are input into the control cabinet 11, the exhaust outlet 33 is closed, materials are put into the extraction tank 3, water is fed into the water tank 1 into the circulation pump 2 and then pumped into the extraction tank 3. During the period when water enters the extraction tank 3 from the circulation pump 2, the water is subjected to temperature treatment through the heat exchanger, which can be high, medium or low temperature to meet the heating or cold extraction requirements. The water enters the extraction tank 3 from the feeding port 31, sprays and soaks the material, and then is discharged from the material outlet 34 to re-enter the circulation pump 2 and pumped into the extraction tank 3 again, thereby realizing continuous extraction of effective components of the material.

[0036] Example 2

[0037] When performing vacuum concentration and extraction, production parameters are input into the control cabinet 11, the exhaust outlet 33 is opened, materials are put into the extraction tank 3, water is fed into the water tank 1 into the circulation pump 2 and then pumped into the extraction tank 3. During the period when water enters the extraction tank 3 from the circulation pump 2, the water is subjected to temperature treatment through the heat exchanger, which can be high, medium or low temperature to meet the heating or cold extraction requirements. The water enters the extraction tank 3 from the feeding port 31, sprays and soaks the material, and then is discharged from the material outlet 34 to re-enter the circulation pump 2 and pumped into the extraction tank 3 again, thereby realizing continuous extraction of effective components of the material.

[0038] Tanning substances and foams generated by the materials during production enter the defoaming separator 4 through the exhaust outlet 33, and the liquid is discharged from the lower outlet 42. After passing through the hot water tank 10, it re-enters the extraction tank 3 through the circulation inlet 32, and the gas is discharged through the upper outlet 41 and enters the condenser 5. After cooling, the gas forms essential oils, pure water and other substances, and enters the essential oil separator 6 for precipitation. The two enter the separation tank 12 for separation. Due to the height difference between the two separation tanks 12, the oil phase is retained in the separation tank 12, and the pure water is discharged into the pure water collection tank 7 and discharged through the lower drain valve 71. The essential oil separator 6 is provided with a pipeline connected to the vacuum pump 8 on the side, and the vacuum pump 8 performs vacuum treatment on the entire system.

[0039] Therefore, the utility model adopts the above-mentioned multifunctional extraction and concentration system, which can perform two operations of extraction and concentration on the material, and the temperature and pressure conditions can be adjusted to achieve various needs such as hot extraction, cold extraction, vacuum concentration, etc., adjust the material-liquid ratio, and realize full utilization of the material.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
