[0002] Rosa roxburghii is a nutritious fruit rich in superoxide dismutase (SOD), ascorbic acid, polyphenols and essential amino acids, and has significant antioxidant, anti-inflammatory and immunomodulatory effects. However, Rosa roxburghii is rich in astringent substances such as tannins, which makes it astringent and affects the taste of Rosa roxburghii juice.

[0003] In the related art, macroporous resin is usually used to adsorb astringent substances in sea buckthorn juice to achieve de-astringency treatment and improve the taste of sea buckthorn juice.

[0038] Combine the following Figure 1-Figure 5 The device 10 for removing astringency from roxburghii juice and the method for using the same, and the device 100 for preparing salad dressing according to the embodiments of the present invention are described in detail.

[0039] Reference Figure 1As shown, the roxburghii juice deastringency device 10 according to the first embodiment of the present invention comprises: a liquid storage tank 1, an eluent tank 2, a first deastringency tube 3, a second deastringency tube 4, a first collecting tank 5, a second collecting tank 6 and a pipeline assembly 7, wherein the liquid storage tank 1 is used to store roxburghii juice, the eluent tank 2 is used to store eluent, the first deastringency tube 3 and the second deastringency tube 4 are both filled with macroporous resin 8, the first collecting tank 5 is used to store the deastringency roxburghii juice after flowing through the first deastringency tube 3 or the second deastringency tube 4, the second collecting tank 6 is used to store the eluent flowing through the first deastringency tube 3 or the second deastringency tube 4, and the pipeline assembly 7 comprises the first collecting tank 5, the second collecting tank 6 and the pipeline assembly 7. An inflow pipeline 71, a second inflow pipeline 72, a first outflow pipeline 73 and a second outflow pipeline 74. The liquid storage tank 1 is optionally connected to the inlet of the first deastringent tube 3 and the inlet of the second deastringent tube 4 through the first inflow pipeline 71, the eluent tank 2 is optionally connected to the inlet of the first deastringent tube 3 and the inlet of the second deastringent tube 4 through the second inflow pipeline 72, the outlet of the first deastringent tube 3 is optionally connected to the first collecting tank 5 and the second collecting tank 6 through the first outflow pipeline 73, and the outlet of the second deastringent tube 4 is optionally connected to the first collecting tank 5 and the second collecting tank 6 through the second outflow pipeline 74.

[0040] It can be understood that the macroporous resin 8 in the first de-astringency tube 3 and the second de-astringency tube 4 are suitable for adsorbing astringent substances such as tannins in the sea buckthorn juice to remove the astringency of the sea buckthorn juice and improve the taste of the sea buckthorn juice. The macroporous resin 8 has little effect on the nutritional components in the sea buckthorn juice, which can reduce the loss of nutrients and ensure the nutritional value of the sea buckthorn juice, which is conducive to improving the product competitiveness of the sea buckthorn juice.

[0041] The eluent stored in the eluent tank 2 can be used to clean the macroporous resin 8 in the first de-astringent tube 3 and the second de-astringent tube 4 to regenerate the macroporous resin 8, thereby achieving the reuse of the macroporous resin 8 and helping to reduce costs. The eluent can be a cleaning solution (70% ethanol), a regeneration solution (acid, alkaline solution), etc.

[0042] The pipeline assembly 7 can realize the flow direction switching function of the sea buckthorn juice and the eluent, so that the first de-astringency pipe 3 and the second de-astringency pipe 4 are always in a complementary state in which one of them performs a de-astringency operation and the other performs a cleaning operation. The sea buckthorn juice de-astringency equipment 10 does not need to be stopped for cleaning, and can achieve continuous production, which is beneficial to improving the de-astringency efficiency of the sea buckthorn juice.

[0043] Specifically, when the first de-astringency pipe 3 is performing a de-astringency operation and the second de-astringency pipe 4 is performing a cleaning operation, the liquid storage tank 1 is connected to the inlet of the first de-astringency pipe 3 through the first inflow pipe 71, the outlet of the first de-astringency pipe 3 is connected to the first collecting tank 5 through the first outflow pipe 73, the eluent tank 2 is connected to the inlet of the second de-astringency pipe 4 through the second inflow pipe 72, and the outlet of the second de-astringency pipe 4 is connected to the second collecting tank 6 through the second outflow pipe 74. The roxburghii juice in the liquid storage tank 1 can flow into the first de-astringency pipe 3 through the first inflow pipe 71 and the inlet of the first de-astringency pipe 3 in turn, and the macroporous resin 8 in the first de-astringency pipe 3 can de-astringe the roxburghii juice. The de-astringency treatment is performed to transform the sea buckthorn juice into de-astringent sea buckthorn juice. The de-astringent sea buckthorn juice can flow to the first collecting tank 5 for storage through the outlet of the first de-astringency tube 3 and the first outflow pipeline 73 in sequence. At the same time, the eluent in the eluent tank 2 can flow into the second de-astringency tube 4 through the second inflow pipeline 72 and the inlet of the second de-astringency tube 4 in sequence. The eluent can clean the macroporous resin 8 in the second de-astringency tube 4, clean off the astringent substances adsorbed by the macroporous resin 8, realize the regeneration of the macroporous resin 8, and restore the adsorption capacity of the macroporous resin 8. Subsequently, the eluent can flow to the second collecting tank 6 for storage through the outlet of the second de-astringency tube 4 and the second outflow pipeline 74 in sequence.

[0044] After the sea buckthorn juice de-astringency equipment 10 has been working for a period of time, the macroporous resin 8 in the first de-astringency tube 3 may have adsorbed a lot of astringent substances and reached saturation, and the macroporous resin 8 is difficult to continue to adsorb astringent substances, while the macroporous resin 8 in the second de-astringency tube 4 has a better adsorption capacity under the cleaning of the eluent. At this time, the first inflow pipeline 71 can be adjusted to be connected to the inlet of the second de-astringency tube 4, the second outflow pipeline 74 can be adjusted to be connected to the first collecting tube, the first outflow pipeline 73 can be adjusted to be connected to the second collecting tank 6, and the second outflow pipeline 74 can be adjusted to be connected to the first collecting tank 5 to achieve the flow direction switching of the sea buckthorn juice and the eluent, so that the first de-astringency tube 3 is cleaned and the second de-astringency tube 4 is de-astringent. That is to say, The sea buckthorn juice in the liquid storage tank 1 can flow into the second de-astringency tube 4 through the second inlet pipe 72 and the inlet of the second de-astringency tube 4 in turn, and the macroporous resin 8 in the second de-astringency tube 4 can de-astringe the sea buckthorn juice. The de-astringent sea buckthorn juice can flow to the first collecting tank 5 through the outlet of the second de-astringency tube 4 and the second outflow pipe 74 in turn for storage. At the same time, the eluent in the eluent tank 2 can flow into the first de-astringency tube 3 through the first inlet pipe 71 and the inlet of the first de-astringency tube 3 in turn to clean out the astringent substances adsorbed by the macroporous resin 8, realize the regeneration of the macroporous resin 8, and restore the adsorption capacity of the macroporous resin 8. Subsequently, the eluent can flow to the second collecting tank 6 through the outlet of the first de-astringency tube 3 and the first outflow pipe 73 in turn for storage.

[0045] According to the sea buckthorn juice de-astringency equipment 10 of the embodiment of the present invention, its pipeline assembly 7 can realize the flow direction switching function of the sea buckthorn juice and the eluent, so that the first de-astringency pipe 3 and the second de-astringency pipe 4 of the sea buckthorn juice de-astringency equipment 10 are always in a complementary state in which one of them performs a de-astringency operation and the other performs a cleaning operation. The sea buckthorn juice de-astringency equipment 10 does not need to be stopped for cleaning, and continuous production can be achieved, which is beneficial to improving the de-astringency efficiency of the sea buckthorn juice.

[0046] In some embodiments of the present invention, reference Figure 1 and Figure 2 As shown, the first inflow pipeline 71 includes: a first connecting pipe 711, a second connecting pipe 712, a third connecting pipe 713 and a first three-way valve 714, the first three-way valve 714 has a first interface 7141, a second interface 7142 and a third interface 7143, the liquid storage tank 1 is connected to the first interface 7141 through the first connecting pipe 711, the second interface 7142 is connected to the inlet of the first de-astringent pipe 3 through the second connecting pipe 712, and the third interface 7143 is connected to the inlet of the second de-astringent pipe 4 through the third connecting pipe 713. The second inflow pipeline 72 includes: a fourth connecting pipe 721, a fifth connecting pipe 722, a sixth connecting pipe 723 and a second three-way valve 724. The second three-way valve 724 has a fourth interface 7241, a fifth interface 7242 and a sixth interface 7243. The eluent tank 2 is connected to the fourth interface 7241 through the fourth connecting pipe 721, the fifth interface 7242 is connected to the inlet of the first de-astringent pipe 3 through the fifth connecting pipe 722, and the sixth interface 7243 is connected to the inlet of the second de-astringent pipe 4 through the sixth connecting pipe 723.

[0047] It can be understood that, in the first three-way valve 714, the first interface 7141 can be selectively connected to the second interface 7142 and the third interface 7143, and the flow direction of the sea buckthorn juice can be flexibly adjusted through the first three-way valve 714. In the second three-way valve 724, the fourth interface 7241 can be selectively connected to the fifth interface 7242 and the sixth interface 7243, and the flow direction of the eluent can be flexibly adjusted through the second three-way valve 724, thereby realizing the switching of the working states of the first de-astringency tube 3 and the second de-astringency tube 4.

[0048] Specifically, when the first interface 7141 is connected with the second interface 7142 and the fourth interface 7241 is connected with the sixth interface 7243, the sea buckthorn juice in the liquid storage tank 1 can flow into the first de-astringent tube 3 through the first connecting pipe 711, the first interface 7141, the second interface 7142, the second connecting pipe 712 and the inlet of the first de-astringent tube 3 in sequence. At the same time, the eluent in the eluent tank 2 can flow into the second de-astringent tube 4 through the fourth connecting pipe 721, the fourth interface 7241, the sixth interface 7243, the sixth connecting pipe 723 and the inlet of the second de-astringent tube 4 in sequence, so that the first de-astringent tube 3 can perform a de-astringent operation and the second de-astringent tube 4 can perform a cleaning operation.

[0049] When the first interface 7141 is connected with the third interface 7143 and the fourth interface 7241 is connected with the fifth interface 7242, the sea buckthorn juice in the liquid storage tank 1 can flow into the second de-astringent tube 4 through the first connecting pipe 711, the first interface 7141, the third interface 7143, the third connecting pipe 713 and the inlet of the second de-astringent tube 4 in sequence. At the same time, the eluent in the eluent tank 2 can flow into the first de-astringent tube 3 through the fourth connecting pipe 721, the fourth interface 7241, the fifth interface 7242, the fifth connecting pipe 722 and the inlet of the first de-astringent tube 3 in sequence, so that the first de-astringent tube 3 can be cleaned and the second de-astringent tube 4 can be de-astringent.

[0050] In some embodiments of the present invention, reference Figure 1 As shown, the sea buckthorn juice deastringency equipment 10 also includes: a first liquid pump 91 and a second liquid pump 92. The first liquid pump 91 is arranged on the first connecting pipe 711, and the first liquid pump 91 is used to pump the sea buckthorn juice to the first interface 7141. The second liquid pump 92 is arranged on the fourth connecting pipe 721, and the second liquid pump 92 is used to pump the eluent to the fourth interface 7241.

[0051] It can be understood that the first liquid pump 91 can provide power for the flow of the sea buckthorn juice, so that the sea buckthorn juice can quickly flow into the first de-astringency tube 3 or the second de-astringency tube 4 to be de-astringent, which is beneficial to improving the de-astringency efficiency of the sea buckthorn juice. The second liquid pump 92 can provide power for the flow of the eluent, so that the eluent can quickly flow into the first de-astringency tube 3 or the second de-astringency tube 4 to clean the macroporous resin 8, which is beneficial to improving the cleaning efficiency.

[0052] In some embodiments of the present invention, reference Figure 1 As shown, the pipeline assembly 7 also includes: a first return pipeline 75 and a second return pipeline 76. The first collecting tank 5 is selectively connected to the liquid storage tank 1 through the first return pipeline 75, and the second collecting tank 6 is selectively connected to the eluent tank 2 through the second return pipeline 76.

[0053] It can be understood that when the first collecting tank 5 is connected to the liquid storage tank 1 through the first reflux pipe 75, the de-astringent sea buckthorn juice after flowing through the first de-astringency pipe 3 or the second de-astringency pipe 4 flows into the first collecting tank 5, and then can continue to flow into the liquid storage tank 1 through the first reflux pipe 75, and then flow into the first de-astringency pipe 3 or the second de-astringency pipe 4 through the first inflow pipe 71 to be de-astringent again, which is beneficial to improving the de-astringency effect of the sea buckthorn juice, thereby helping to improve the taste of the sea buckthorn juice and enhance the product competitiveness of the sea buckthorn juice.

[0054] When the second collecting tank 6 is connected to the eluent tank 2 through the second reflux pipe 76, the eluent flowing through the first de-astringent tube 3 or the second de-astringent tube 4 flows into the eluent tank 2, and then can continue to flow back to the eluent tank 2 through the second reflux pipe 76, and then can flow to the first de-astringent tube 3 or the second de-astringent tube 4 again through the second inflow pipe 72, thereby realizing the reuse of the eluent, which is beneficial to cost saving.

[0055] Reference Figure 1 As shown, the first return line 75 is provided with a third flow control valve 793, which is suitable for adjusting the flow of the first return line 75, so that the first collection tank 5 can be selectively connected to the liquid storage tank 1 through the first return line 75, and the second return line 76 is provided with a fourth flow control valve 794, which is suitable for adjusting the flow of the second return line 76, so that the second collection tank 6 can be selectively connected to the eluent tank 2 through the second return line 76. Among them, the third flow control valve 793 and the fourth flow control valve 794 can both be ball valves, which have lower costs.

[0056] In some embodiments of the present invention, reference Figure 1 As shown, the sea buckthorn juice de-astringency equipment 10 also includes: a flow controller 93, which is installed on the pipeline assembly 7. The flow controller 93 is used to detect and control the flow of each pipeline in the pipeline assembly 7, and can accurately control the flow of the sea buckthorn juice to adjust the de-astringency efficiency of the sea buckthorn juice. It can also accurately control the flow of the eluent to adjust the cleaning efficiency, and can be flexibly adjusted according to production needs.

[0057] For example, refer to Figure 1 As shown, the first return line 75 and the second return line 76 are both installed with flow controllers 93, and the two flow controllers 93 are respectively a first flow controller 93a and a second flow controller 93b. The first flow controller 93a is installed on the first return line 75, and is used to detect and control the flow of the sea buckthorn juice in the first return line 75, and the second flow controller 93b is installed on the second return line 76, and is used to detect and control the flow of the eluent in the second return line 76.

[0058] Among them, the flow controller 93 includes a pressure sensor 931, a pressure regulating valve 932 and a standard pressure gauge 933, and can be connected to an integrated sensor and a PLC control system, and can use a computer program to realize automatic operation. The flow controller 93 can control the power of the first liquid pump 91 and the second liquid pump 92 through an intelligent control system (PLC control system) to control the flow rate of the sea buckthorn juice and the eluent respectively, thereby controlling the flow rate of the sea buckthorn juice and the eluent. The pressure sensor 931 can monitor the pipeline pressure, and is also equipped with a leakage monitoring and high-pressure protection system. It can automatically stop in an emergency to ensure production safety.

[0059] In some embodiments of the present invention, reference Figure 1 As shown, a first flow control valve 77 is provided at the inlet of the first de-astringency pipe 3, and the first flow control valve 77 is used to control the inflow flow of the first de-astringency pipe 3. A second flow control valve 78 is provided at the inlet of the second de-astringency pipe 4, and the second flow control valve 78 is used to control the inflow flow of the second de-astringency pipe 4. Through the first flow control valve 77 and the second flow control valve 78, the de-astringency efficiency and cleaning efficiency of the roxburghii juice de-astringency device 10 can be flexibly adjusted to meet production needs. Among them, the first flow control valve 77 and the second flow control valve 78 can both be ball valves, which are relatively low in cost.

[0060] It can be understood that when the first de-astringency pipe 3 is performing a de-astringency operation and the second de-astringency pipe 4 is performing a cleaning operation, the first flow control valve 77 controls the inflow flow of the first de-astringency pipe 3, which can control the flow of the sea buckthorn juice flowing into the first de-astringency pipe 3, thereby adjusting the de-astringency efficiency of the sea buckthorn juice, and the second flow control valve 78 controls the inflow flow of the second de-astringency pipe 4, which can control the flow of the eluent flowing into the second de-astringency pipe 4, thereby adjusting the cleaning efficiency.

[0061] When the first de-astringency pipe 3 is undergoing a cleaning operation and the second de-astringency pipe 4 is undergoing a de-astringency operation, the first flow control valve 77 controls the inflow flow of the first de-astringency pipe 3, thereby controlling the flow of the sea buckthorn juice flowing into the first de-astringency pipe 3, thereby adjusting the de-astringency efficiency of the sea buckthorn juice, and the second flow control valve 78 controls the inflow flow of the second de-astringency pipe 4, thereby controlling the flow of the eluent flowing into the second de-astringency pipe 4, thereby adjusting the cleaning efficiency.

[0062] In some embodiments of the present invention, reference Figure 1 As shown, a first flow meter 791 is provided at the outlet of the first de-astringency pipe 3, and the first flow meter 791 is used to detect the outflow flow of the first de-astringency pipe 3. A second flow meter 792 is provided at the outlet of the second de-astringency pipe 4, and the second flow meter 792 is used to detect the outflow flow of the second de-astringency pipe 4. The de-astringency efficiency and cleaning efficiency of the sea buckthorn juice de-astringency equipment 10 can be detected by the first flow meter 791 and the second flow meter 792.

[0063] It can be understood that when the first de-astringency tube 3 is performing a de-astringency operation and the second de-astringency tube 4 is performing a cleaning operation, the first flow meter 791 detects the outflow flow of the first de-astringency tube 3, which can detect the flow of the de-astringent sea buckthorn juice, thereby detecting the de-astringency efficiency of the sea buckthorn juice, and the second flow meter 792 detects the outflow flow of the second de-astringency tube 4, which can detect the flow of the eluent flowing through the second de-astringency tube 4, thereby detecting the cleaning efficiency.

[0064] When the second de-astringency pipe 4 is performing a de-astringency operation and the first de-astringency pipe 3 is performing a cleaning operation, the second flow meter 792 detects the outflow flow of the second de-astringency pipe 4, so as to detect the flow of the de-astringent sea buckthorn juice, thereby detecting the de-astringency efficiency of the sea buckthorn juice. The first flow meter 791 detects the outflow flow of the first de-astringency pipe 3, so as to detect the flow of the eluent flowing through the first de-astringency pipe 3, thereby detecting the cleaning efficiency.

[0065] In some embodiments of the present invention, the macroporous resin 8 is a non-polar resin, and the average pore size d satisfies the relationship: 15nm≤d≤30nm, for example, d can be 15nm, 20nm, 25nm, 30nm, etc., which is beneficial to ensure the adsorption capacity of the macroporous resin 8 and improve the de-astringency efficiency.

[0066] It can be understood that when d is less than 15 nm, the average pore size of the macroporous resin 8 is small, and it is difficult to adsorb astringent substances such as tannins with larger molecules, and the de-astringency efficiency is low. When d is greater than 30 nm, the average pore size of the macroporous resin 8 is large, the specific surface area is small, and the adsorption capacity of the macroporous resin 8 is low, resulting in an increase in the regeneration frequency of the macroporous resin 8, resulting in a large consumption of eluent and high cost. In the present embodiment, d is in the range of 15 nm to 30 nm, the average pore size of the macroporous resin 8 is moderate, and astringent substances such as tannins with larger molecules can be effectively adsorbed, which can improve the de-astringency efficiency. In addition, the adsorption capacity of the macroporous resin 8 is high, and a large amount of astringent substances can be adsorbed. The regeneration frequency of the macroporous resin 8 is low, which can reduce the consumption of eluent and save costs.

[0067] Among them, the model of the macroporous resin 8 can be X-5, which has a strong adsorption effect on astringent substances and pigment substances. X-5 has the advantages of large specific surface area, strong adsorption, easy elution, high mechanical strength, anti-pollution, easy regeneration, etc. It can be used to remove the astringency of sea buckthorn juice and is suitable for industrial production.

[0068] In some embodiments of the present invention, reference Figure 1 As shown, there are multiple first de-astringency tubes 3, which are arranged in parallel, and there are multiple second de-astringency tubes 4, which are arranged in parallel, which is beneficial to improving the de-astringency efficiency of the sea buckthorn juice de-astringency equipment 10 for sea buckthorn juice, so as to improve the production capacity of the sea buckthorn juice de-astringency equipment 10.

[0069] It can be understood that when multiple first de-astringency tubes 3 are performing de-astringency operations, the flow areas of the multiple first de-astringency tubes 3 are relatively large, which can increase the flow rate of the sea buckthorn juice and improve the de-astringency efficiency of the sea buckthorn juice, which is beneficial to improving the production capacity of the sea buckthorn juice de-astringency equipment 10, and the multiple first de-astringency tubes 3 can make the sea buckthorn juice flow in a dispersed manner, which can reduce the flow rate of the sea buckthorn juice entering a single first de-astringency tube 3, thereby shortening the time for the macroporous resin 8 in the single first de-astringency tube 3 to adsorb astringent substances to reach saturation, which is beneficial to the smooth progress of the sea buckthorn juice de-astringency operation.

[0070] Similarly, when multiple second de-astringency tubes 4 are performing de-astringency operations, the flow areas of the multiple second de-astringency tubes 4 are larger, which can increase the flow rate of the sea buckthorn juice and improve the de-astringency efficiency of the sea buckthorn juice, which is beneficial to improving the production capacity of the sea buckthorn juice de-astringency equipment 10, and the multiple second de-astringency tubes 4 can make the sea buckthorn juice flow in a dispersed manner, which can reduce the flow rate of the sea buckthorn juice entering a single second de-astringency tube 4, thereby shortening the time for the macroporous resin 8 in a single second de-astringency tube 4 to adsorb astringent substances to reach saturation, which is beneficial to the smooth progress of the sea buckthorn juice de-astringency operation.

[0071] In some embodiments, the number of the first de-astringency tube 3 and the second de-astringency tube 4 can be 4 to 8, so that a large amount of roxburghii juice can be de-astringented at the same time. The specific number can be adjusted according to actual production needs.

[0072] In some embodiments of the present invention, the diameter-to-height ratio of the first de-astringency tube 3 and the second de-astringency tube 4 can be 1:25-1:10, the sample loading volume can be 1BV-4BV, and the sample loading flow rate can be 1BV / h-7BV / h, which can effectively de-astringe the sea buckthorn juice.

[0073] In some embodiments of the present invention, the first de-astringent tube 3 and the second de-astringent tube 4 can be made of transparent tempered glass to facilitate observation of the treatment process in the first de-astringent tube 3 and the second de-astringent tube 4, and the first de-astringent tube 3 and the second de-astringent tube 4 can be disassembled to facilitate replacement of the macroporous resin in the first de-astringent tube 3 and the second de-astringent tube 4.

[0074] In some embodiments of the present invention, reference Figure 1 As shown, the sea buckthorn juice deastringency equipment 10 also includes a first one-way valve 94 and a second one-way valve 95. The sea buckthorn juice supply equipment for supplying sea buckthorn juice can be connected to the liquid storage tank 1 in one direction through the first one-way valve 94, and the eluent supply equipment for supplying eluent can be connected to the liquid storage tank 1 in one direction through the second one-way valve 95.

[0075] Embodiment 1: Concentrated roxburghii juice is processed by roxburghii juice deastringency equipment 10, the model of macroporous resin 8 adopts X-5, only one first deastringency tube 3 or one second deastringency tube 4 is used to process roxburghii juice, the flow rate is set to 10L / h, the processing time is 20 minutes, and the processing capacity is 10 / 3L.

[0076] Embodiment 2: Concentrated roxburghii juice is processed by roxburghii juice deastringency equipment 10, the model of macroporous resin 8 adopts X-5, three first deastringency tubes 3 or three second deastringency tubes 4 are used in parallel to process roxburghii juice, the flow rate is set to 10L / h, the processing time is 1 hour, and the processing capacity is 30L.

[0077] Comparative Example 1: Rosa roxburghii juice was treated according to the method of Example 2, except that the model of macroporous resin 8 was replaced by NKA-9.

[0078] Among them, X-5 is a non-polar material with a white opaque spherical appearance, a particle size of 0.3mm to 1.25mm, and a specific surface area of ​​500m 2 / g~600m 2 / g, the average pore size is 29nm~30nm, NKA-9 is a polar material, with a slightly yellowish opaque spherical appearance, a particle size of 0.315mm~1.25mm, and a specific surface area of ​​250m 2 / g~290m 2 / g, and the average pore size is 15.5nm~16.5nm.

[0079] In some embodiments of the present invention, Figure 3 The sensory evaluation diagrams of the de-astringent roxburghii juice obtained in Example 1, Example 2 and Comparative Example 1 and the roxburghii juice without de-astringent treatment are shown. It can be understood that the adsorption effect of the roxburghii juice will deteriorate with the increase of the treatment time (treatment amount) of the macroporous resin 8. Therefore, Example 1 has the best adsorption effect and the lightest bitter taste due to the small amount of roxburghii juice treated. However, according to the sensory evaluation results of the crowd, the value of the bitter taste is not the smaller the better. Consumers prefer the product in Example 2, that is, the product with a treatment time (treatment amount) three times that of Example 1. The NKA-9 in Comparative Example 1 is less than 10% of the product in Example 1. The NKA-9 resin with a polarity and a small average pore size has a poor adsorption effect on tannins and a poor de-astringency effect. In Examples 1 and 2, the X-5 resin with a non-polarity and a larger average pore size has a better adsorption effect on tannins and a better de-astringency effect.

[0080] In some specific embodiments of the present invention, when the sea buckthorn juice deastringency device 10 is used to deastringe the sea buckthorn juice, three first deastringency pipes 3 can be used in parallel to treat the sea buckthorn juice, with a flow rate set to 10 L / h, a processing time of 1 hour, and a processing volume of 30 L.

[0081] After 1 hour, the first three-way valve 714 and the second three-way valve 724 are used to change the flow path, and the sea buckthorn juice enters the three second de-astringency tubes 4 for further processing for 1 hour. At this time, the three first de-astringency tubes 3 perform elution operations. Specifically, when the three first de-astringency tubes 3 perform elution operations, distilled water is added to the eluent tank 2 for flushing in the first 10 minutes at a flow rate of 30 L / h. From 10 to 50 minutes, 70% food-grade alcohol is added to the eluent tank 2 for flushing at a flow rate of 10 L / h. From 50 to 60 minutes, distilled water is added to the eluent tank 2 for flushing at a flow rate of 30 L / h. After the flushing is completed, the flow path can still be changed through the first three-way valve 714 and the second three-way valve 724 to complete the exchange of adsorption and elution, thereby realizing uninterrupted cyclic production.

[0082] According to the sea buckthorn juice de-astringency equipment 10 of the embodiment of the present invention, the macroporous resin 8 selectively adsorbs astringent substances such as tannins, has high de-astringency efficiency, is green and environmentally friendly, does not use harmful chemical reagents, and is environmentally friendly. The macroporous resin 8 can also retain vitamin C, SOD and other nutrients in the sea buckthorn juice during the de-astringency process. The macroporous resin 8 can be regenerated by the eluent to achieve repeated use, which is beneficial to reducing the cost of use. The sea buckthorn juice de-astringency equipment 10 can have the advantages of high efficiency, greenness and sustainability. By adjusting the flow rate, the amount of macroporous resin 8 and the adsorption time, the de-astringency effect can be flexibly adjusted. The process controllability of the sea buckthorn juice de-astringency equipment 10 is strong. The sea buckthorn juice de-astringency equipment 10 helps to expand the sea buckthorn market and can enable the upgrading of the sea buckthorn industry.

[0083] Reference Figure 4 As shown, according to the use method of the roxburghii juice de-astringency device 10 according to the second aspect of the present invention, the roxburghii juice de-astringency device 10 is the roxburghii juice de-astringency device 10 of the above embodiment, and the use method includes:

[0084] Step S1: Control the inlet of the first deastringent tube to be connected to the liquid storage tank through the first inflow pipeline, the outlet of the first deastringent tube to be connected to the first collecting tank through the first outflow pipeline, the inlet of the second deastringent tube to be connected to the elution liquid tank through the second inflow pipeline, and the outlet of the second deastringent tube to be connected to the second collecting tank through the second outflow pipeline, and continue for a first preset time.

[0085] Among them, the roxburghii juice in the liquid storage tank 1 can flow into the first de-astringent tube 3 through the first inflow pipeline 71 and the inlet of the first de-astringent tube 3 in turn, the macroporous resin 8 in the first de-astringent tube 3 can de-astringent the roxburghii juice, and the de-astringent roxburghii juice can flow to the first collection tank 5 through the outlet of the first de-astringent tube 3 and the first outflow pipeline 73 in turn for storage, and at the same time, the eluent in the eluent tank 2 can flow into the second de-astringent tube 4 through the second inflow pipeline 72 and the inlet of the second de-astringent tube 4 in turn, and the eluent can clean the macroporous resin 8 in the second de-astringent tube 4, and can clean the astringent substances adsorbed by the macroporous resin 8, so as to achieve the regeneration of the macroporous resin 8 and restore the adsorption capacity of the macroporous resin 8, and then the eluent can flow to the second collection tank 6 through the outlet of the second de-astringent tube 4 and the second outflow pipeline 74 in turn for storage. That is to say, while the first de-astringent tube 3 is performing the de-astringent operation, the second de-astringent tube 4 is performing the cleaning operation.

[0086] Step S2: Control the inlet of the first deastringent tube to be connected with the elution liquid tank through the second inflow pipeline, the outlet of the first deastringent tube to be connected with the second collecting tank through the first outflow pipeline, the inlet of the second deastringent tube to be connected with the liquid storage tank through the first inflow pipeline, and the outlet of the second deastringent tube to be connected with the first collecting tank through the second outflow pipeline, and continue for a second preset time.

[0087] Among them, after the sea buckthorn juice de-astringency equipment 10 has been working continuously for the first preset time, the macroporous resin 8 in the first de-astringency tube 3 may have adsorbed a large amount of astringent substances and reached saturation, and the macroporous resin 8 is difficult to continue to adsorb astringent substances, while the macroporous resin 8 in the second de-astringency tube 4 has a better adsorption capacity under the cleaning of the eluent.

[0088] By adjusting the first inflow pipeline 71 to be connected to the inlet of the second de-astringency pipe 4, adjusting the second outflow pipeline 74 to be connected to the first collecting pipe, adjusting the first outflow pipeline 73 to be connected to the second collecting tank 6, and adjusting the second outflow pipeline 74 to be connected to the first collecting tank 5, the first de-astringency pipe 3 is cleaned and the second de-astringency pipe 4 is de-astringent. That is, the roxburghii juice in the liquid storage tank 1 can flow into the second de-astringency pipe 4 through the second inflow pipeline 72 and the inlet of the second de-astringency pipe 4 in turn, and the macroporous resin 8 in the second de-astringency pipe 4 The sea buckthorn juice can be treated to remove the astringency. The sea buckthorn juice after the astringency is removed can flow to the first collecting tank 5 for storage through the outlet of the second de-astringency tube 4 and the second outflow pipeline 74 in sequence. At the same time, the eluent in the eluent tank 2 can flow into the first de-astringency tube 3 through the first inflow pipeline 71 and the inlet of the first de-astringency tube 3 in sequence to clean out the astringent substances adsorbed by the macroporous resin 8, achieve the regeneration of the macroporous resin 8, and restore the adsorption capacity of the macroporous resin 8. Subsequently, the eluent can flow to the second collecting tank 6 for storage through the outlet of the first de-astringency tube 3 and the first outflow pipeline 73 in sequence.

[0089] According to the method of using the sea buckthorn juice deastringency equipment 10 in an embodiment of the present invention, the pipeline assembly 7 of the sea buckthorn juice deastringency equipment 10 can realize the flow direction switching function of the sea buckthorn juice and the eluent, so that the first deastringency tube 3 and the second deastringency tube 4 of the sea buckthorn juice deastringency equipment 10 are always in a complementary state in which one of them performs a deastringency operation and the other performs a cleaning operation. The sea buckthorn juice deastringency equipment 10 does not need to be stopped for cleaning, and continuous production can be achieved, which is beneficial to improving the deastringency efficiency of the sea buckthorn juice.
