Technical Field
[0001] The utility model relates to the technical field of aromatic plant hydrosol processing, in particular to a storage tank for temporarily storing and preprocessing aromatic plant hydrosol. Background Art
[0002] Hydrosol, also known as hydrolat, refers to the water left over during the distillation and extraction of essential oils. It is a by-product of essential oils and is a 100% saturated pure hydrosol separated during the process of refining essential oils. Its components are natural and pure, and the fragrance is light and pleasant. Hydrosol is generally obtained by extracting aromatic plants, and common hydrosols include rose hydrosol, lavender hydrosol, rosemary hydrosol, etc.
[0003] Since aromatic plant hydrosol is a distillation extraction product, after the extraction is completed, there will be some solid impurities such as aromatic plant residues and precipitates in the hydrosol. The existence of these impurities will reduce the purity of the hydrosol and significantly reduce its quality.
[0004] Based on this, the utility model provides a storage tank for temporarily storing and preprocessing aromatic plant hydrosol, which can effectively improve the purity of the hydrosol. Content of the Utility Model
[0005] The purpose of the utility model is to provide a storage tank for temporarily storing and preprocessing aromatic plant hydrosol, which can effectively remove solid impurities such as aromatic plant residues and precipitates, and effectively improve the purity and quality of aromatic plant hydrosol.
[0006] The purpose of the utility model is achieved by the following technical solutions:

[0023] Embodiment 1
[0024] Since the aromatic plant hydrosol is a distillation extraction product, after the extraction is completed, there will be some solid impurities such as aromatic plant residues and precipitates in the hydrosol. The presence of these impurities will reduce the purity of the hydrosol and significantly degrade its quality.
[0025] Based on this, the present utility model provides a storage tank for temporarily storing and pre-treating aromatic plant hydrosol, as Figure 1 shown, which includes a storage tank body 1, a feeding device connected to the storage tank body 1, and a sewage discharge pipe 2 provided at the bottom end of the storage tank body 1. As Figure 1 shown, the sewage discharge pipe 2 is connected to the blending device 11 through the conveying pipe 10, and the blending device 11 is connected to the feeding device through the first circulation pipeline 3; a first filtration device 4 is provided on the sewage discharge pipe 2, and a second filtration device 5 and a sanitary pump 13 are provided on the conveying pipe 10; the pore diameter of the filter holes of the first filtration device 4 is larger than the pore diameter of the filter holes of the second filtration device 5. Further, as Figure 1 shown, the feeding device includes a feed pipe 6 penetrating through the side wall of the storage tank body 1 and extending into the interior of the storage tank body 1, and a spraying device (prior art, such as a spray head, not shown in the figure) provided at the liquid outlet end of the feed pipe 6. Further, as Figure 1 shown, the first filtration device 4 is a detachable 300-mesh filter cloth. Further, the second filtration device 5 is a 0.22-μm microporous membrane filtration device (the filter holes defined in the first filtration device 4 and the second filtration device 5 in the present utility model can meet the filtration requirements of common aromatic plant hydrosols such as rose hydrosol). Further, a valve 12 is provided on the sewage discharge pipe 2, and the valve 12 on the sewage discharge pipe 2 is provided between the storage tank body 1 and the first filtration device 4.
[0026] Working principle: the rose hydrosol obtained by primary processing (the pretreatment storage tank in the utility model is not only suitable for rose hydrosol, but also for other aromatic plant hydrosols such as lavender hydrosol, rosemary hydrosol, etc.) is pumped into the feed pipe 6, and then passed into the spray device along the feed pipe 6, and finally sprayed evenly into the storage tank body 1 through the spray device for storage. During the long-term storage of the hydrosol, solid impurities such as aromatic plant residues and precipitates in the hydrosol will settle at the bottom of the storage tank body 1 due to gravity. After the sedimentation is substantially complete, the valve 12 on the drain pipe 2 is opened to discharge the settled solid impurities through the drain pipe 2, and then the solid impurities with a size larger than the filter pore size of the 300-mesh filter cloth are filtered through the first filter device 4, and then the solid impurities with a size larger than 0.22um are filtered through the second filter device 5; then, under the action of the sanitary pump 13, the filtered impurities are discharged along the conveying pipe. 10 is introduced into the mixing device 11 for mixing, such as adding preservatives, etc. This device is a prior art and will not be described in detail here; the mixed hydrosol continues to enter the feed pipe 6 along the first circulation pipe 3, and then is introduced into the storage tank body 1 along the feed pipe 6. Because the hydrosol can be circulated multiple times through the storage tank body 1, the drain pipe 2, the delivery pipe 10, the first circulation pipe 3, and the feed pipe 6, during the multiple circulation processes, the upper liquid, middle liquid, and bottom liquid of the hydrosol in the storage tank body 1 can be mixed uniformly, which effectively improves the uniformity of the hydrosol and further improves the quality of the hydrosol.
[0027] Example 2
[0028] Generally speaking, the aromatic plant hydrosol after production will contain a certain proportion of aromatic plant essential oils, whose density is less than that of the hydrosol. After the hydrosol is stored in the storage tank body 1 for a period of time, the essential oils in the hydrosol will slowly precipitate out of the surface and present an oil-water separation state with the hydrosol. In order to effectively collect these essential oils, based on Example 1, as Figure 2 As shown, an oil-water separator 7 (existing technology, the principle of which will not be elaborated here) is arranged on the top of the storage tank body 1, and an essential oil collection pipe 8 is arranged at the liquid outlet end of the oil-water separator 7.
[0029] In specific implementation, when the essential oil is precipitated from the top surface of the hydrosol and presents an oil-water separation state with the hydrosol, the oil-water separator 7 is opened to separate the essential oil from the surface of the hydrosol, and the separated essential oil is led out along the essential oil collection tube 8, thereby realizing the collection of the essential oil to further improve the purity of the hydrosol. At the same time, because the hydrosol and the essential oil can each play their own value, the product value is effectively improved.
[0030] Example 3
[0031] Because the aromatic substances in the hydrosol in Example 1 or Example 2 are repeatedly circulated, the aromatic substances in the hydrosol will also undergo filtering operations multiple times, which will cause aroma loss and thus affect the quality of the hydrosol. In order to avoid the loss of aromatic substances to the greatest extent,Figure 3 As shown, a second circulation pipeline 9 is connected to the lower part of the storage tank body 1, and one end of the second circulation pipeline 9 far from the storage tank body 1 is connected to a delivery pipe 10; the sanitary pump is arranged between the second circulation pipeline 9 and the dispensing device 11. Further, a valve 12 is arranged on the second circulation pipeline 9.
[0032] Specifically, during the circulation operation of the hydrosol, it can circulate no more than 3 times through the storage tank body 1, the sewage discharge pipe 2, the delivery pipe 10, the first circulation pipeline 3, and the feed pipe 6 to remove the solid impurities in the hydrosol to the greatest extent. In subsequent circulation operations, the valve 12 in the sewage discharge pipe 2 is closed. Thereafter, the valve 12 on the second circulation pipeline 9 is opened, so that the hydrosol circulates through the storage tank body 1, the second delivery pipe 10, the delivery pipe 10, the first circulation pipeline 3, and the feed pipe 6. In the subsequent circulation process, it is mainly used to improve the uniformity of the hydrosol in the storage tank body 1. In this solution, by replacing the circulation pipeline of the hydrosol, the filtration times of the hydrosol can be effectively reduced, thereby maximizing the loss of aromatic substances in the hydrosol and maximizing the preservation of the value of the hydrosol.
