Description

Technical Field

[0002] Essential oil, also known as volatile oil, mainly refers to oily fragrant substances extracted from parts such as flowers, leaves, roots, barks, stems, branches, fruits, and seeds of aromatic plants by steam distillation, pressing, cold grinding, or dry distillation processes. It is widely used in perfumes, cosmetics, food additives, and healthcare products and is highly regarded for its unique aroma and biological activity.

[0003] Steam distillation is the most important method for essential oil extraction. This method involves co-heating a plant material containing volatile components with water for distillation, so that the volatile components are steamed out together with the steam. Subsequently, through the condensation process, the volatile components are separated from the water phase, thereby realizing the collection of essential oil. For example, clove bud oil and rose essential oil can both be extracted by this method.

Research shows that although some low-content components in essential oil have a low proportion, they have extremely important aroma characteristics and biological activity values. Therefore, if the on-line in-situ conversion of key components of essential oil can be realized through reactions during extraction, and the ratio between important components can be regulated to further improve the quality of essential oil, it is of great significance for the preparation and application of essential oil.

The steam source 1 supplies steam to the first cavity 211, and the second cavity 212 is connected to the chemical reaction unit 3; the chemical reaction unit 3 is detachably arranged between the distillation chamber 2 and the connecting pipe 4, and a movable unit 31 is detachably installed inside it. The movable unit 31 is vertically through, and chemical reagents are arranged inside. Those skilled in the art can optimize parameters such as the type, quantity, and reaction time of the chemical reagents according to the type of essential oil and the required chemical composition to achieve the best extraction effect.

[0037] Specifically, the steam source 1 is a steam generator, which is arranged outside the distillation chamber 2, and one end of it is connected to the first cavity 211 through a pipe. According to the required steam flow rate, pressure, and steam temperature for distillation and purification, the flow rate entering the steam generator and the heating temperature of the steam generator are regulated so that the liquid water is completely evaporated in the steam generator to form high-temperature steam. The high-temperature steam enters the first cavity 211 of the distillation chamber 2. The through holes on the material partition 21 allow the steam to pass through. The steam contacts and heats the plant materials on the material partition 21. The volatile essential oil components in the plant materials are quickly vaporized under the action of the high temperature and high heat of the steam and enter the chemical reaction unit 3 together with the steam. Those skilled in the art can also, according to needs, adopt steam sources 1 with different setting forms and different setting positions. For example, a container for holding liquid water and a heating component for heating the liquid water are arranged in the first cavity 211, and the same technical effect can be achieved.

[0038] Specifically, the movable unit 31 and the chemical reaction unit 3 are of a double-layer tube structure arranged from the inside out. The movable unit 31 is detachably installed in the chemical reaction unit 3 as the outer layer tube as the inner layer tube. The chemical reagents can be directly filled in the movable unit 31 or placed in the movable unit 31 through a support plate. The lower end of the chemical reaction unit 3 is connected to the distillation chamber 2 through a clamp, and the upper end of the chemical reaction unit 3 is connected to the inlet end of the connecting pipe 4 through a clamp. Such a setting is convenient for disassembly and cleaning, and at the same time, it is also convenient to replace chemical reagents. After the steam carries the volatile essential oil components into the chemical reaction unit 3, the volatile essential oil components react with the chemical reagents in the movable unit 31 to in-situ online change the proportion of some important components in the volatile essential oil components. The steam continues to carry the volatile essential oil components with the proportion of some important components changed into the connecting pipe 4.

[0039] Specifically, the outlet end of the connecting pipe 4 is detachably connected to the upper end of the condenser 5 through a clamp, which facilitates the maintenance or replacement of the condenser 5 and the connecting pipe 4. The water vapor carries the volatile essential oil components with the proportion of some important components changed and enters the condenser 5 from the outlet end of the connecting pipe 4 through the connecting pipe 4.

[0040] Specifically, the condenser 5 includes a second pipe body 52 and a first pipe body 51 sleeved outside the second pipe body 52. The second pipe body 52 is detachably connected between the connecting pipe 4 and the oil-water separator 6, which facilitates the maintenance and cleaning of the condenser 5, the connecting pipe 4 and the oil-water separator 6. The upper end of the first pipe body 51 is provided with a condensate outlet 511, and the lower end is provided with a condensate inlet 512. The condensate inlet 512 is communicated with a cooling water source. After the water vapor carrying the volatile essential oil components with the proportion of some important components changed enters the second pipe body 52 from the connecting pipe 4, the cooling water in the first pipe body 51 enters from the condensate inlet 512 and flows out from the condensate outlet 511. As the cooling water flows, the water vapor and the volatile essential oil components with the proportion of some important components changed are cooled and form a liquid state and flow into the oil-water separator 6.

[0041] Those skilled in the art can also choose other detachable connection methods according to needs to replace the above-mentioned clamp connection method, such as threaded connection, etc.

[0042] Specifically, the oil-water separator 6 is vertically arranged and includes a transparent pipe and a switch arranged at the lower end of the transparent pipe. Under the action of gravity, essential oil and water with different densities will be stratified. The operator can clearly observe the boundary between the essential oil layer and the water layer through the transparent pipe and selectively release water or essential oil by controlling the switch of the transparent pipe. The specific form of the switch is not limited and can be a knob switch, a valve, or a push-button switch. The transparent pipe can be made of transparent materials such as glass and transparent ceramics.

[0043] The working principle of the present utility model is as follows: Before use, place the plant extraction material on the material partition 21, set the chemical reagent in the movable unit 31, then put the movable unit 31 into the chemical reaction unit 3, and then connect the distillation chamber 2, the chemical reaction unit 3, the connecting pipe 4, the condenser 5 and the oil-water separator 6 in sequence through clamps; During use, the steam source 1 inputs steam into the first cavity 211, and the steam passes through the through holes of the material partition 21 and fully contacts the plant material. The volatile essential oil components in the plant material are vaporized due to the heating of the steam, and the steam carries the volatile essential oil components into the chemical reaction unit 3, and reacts with the chemical reagent in the movable unit 31 to change the proportion of some important components of the volatile essential oil components, thereby realizing the selective conversion and optimization of the volatile essential oil components. After being processed by the chemical reaction unit 3, the steam carries the volatile essential oil components with the proportion of some important components changed into the second pipe body 52 of the condenser 5 through the connecting pipe 4. The cooling water flows in from the condensate inlet 512 and flows downward along the inside of the first pipe body 51 and flows out from the condensate outlet 511. As the cooling water flows, the steam and the volatile essential oil components with the proportion of some important components changed are cooled and form a liquid state and flow into the oil-water separator 6. After standing and stratifying, an essential oil layer and a water layer are formed, and the boundary between the essential oil layer and the water layer can be clearly observed through the transparent pipe. By opening and closing the transparent pipe, water or essential oil can be selectively released.

[0044] The above-mentioned plant materials are not limited to single types of plant materials. By adjusting parameters such as chemical reagents and steam temperature, it can adapt to the extraction requirements of a variety of different essential oils, and has good versatility and expandability.

[0045] The following is an application embodiment of the present utility model:

[0046] Load the plant material cloves buds to be extracted onto the material partition plate 21 in the distillation chamber 2. A certain proportion of the chemical reagent cobalt chloride is provided in the movable unit 31 within the chemical reaction unit 3. After the device is started, the water vapor generated by the water vapor source 1 is introduced into the first cavity 211 of the distillation chamber 2. As the water vapor rises, it passes through the through holes on the material partition plate 21 and enters the second cavity 212. The water vapor comes into direct contact with the cloves buds, and the volatile essential oil components in the cloves buds are vaporized due to the heating of the water vapor. The water vapor carries the volatile cloves bud oil components into the chemical reaction unit 3, and the volatile cloves bud oil components react rapidly with the chemical reagent cobalt chloride in the movable unit 31, causing the isomerization of eugenol in the volatile cloves bud oil components and generating a certain proportion of isoeugenol. The water vapor carries the volatile cloves bud oil components with the proportion of some important components changed through the connecting pipe 4 into the second pipe body 52 of the condenser 5. Cooling water enters from the condensate inlet 512 and flows out from the condensate outlet 511. As the cooling water flows, in the condenser 5, the water vapor carrying the volatile cloves bud oil components with the proportion of some important components changed is cooled and condensed into a liquid and flows into the oil-water separator 6 for static separation. Since the cloves bud oil is heavy oil, after stable separation, directly turn on the switch and release the lower layer to obtain the cloves bud oil in which the important components eugenol and isoeugenol have changed.

[0047] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
