Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of fruit juice processing, and in particular to a fruit juice degassing device. Background Technology
[0002] During fruit juice processing, a large amount of gas (such as oxygen and carbon dioxide) is introduced. These gases mainly originate from the intercellular spaces of the fruit, mechanical contact during processing, and ambient air. Oxygen dissolved in the juice triggers oxidation reactions, leading to the degradation of nutrients such as vitamin C and pigments (e.g., anthocyanins), resulting in browning, flavor deterioration, and aroma loss. For example, the oxidation of vitamin C reduces the nutritional value of the juice, while pigment oxidation directly affects the product's appearance and consumer acceptance. Therefore, degassing is a crucial step in fruit juice processing, aiming to extend shelf life and maintain sensory quality and nutritional integrity.
[0003] Traditional juice degassing devices (such as vacuum degassing tanks) typically have the filter screen directly installed at the top of the tank. Juice is fed in from the top and filtered through the screen, trapping pulp and other impurities to prevent clogging of subsequent pipes or affecting degassing efficiency. However, filter clogging or routine maintenance requires disassembling the vacuum tank for cleaning, which is time-consuming and labor-intensive, thus impacting degassing efficiency. Utility Model Content
[0004] This utility model aims to at least partially solve one of the technical problems in the related art.
[0005] Therefore, the purpose of this utility model is to propose a juice degassing device that uses sedimentation to remove impurities, eliminating the need to disassemble the filter screen inside the vacuum tank, thereby reducing the labor intensity of relevant personnel and improving the degassing efficiency of the juice.

One end of the sedimentation cylinder is connected to the bottom of the vacuum tank, and the other end is connected to the collection box. A first valve body is installed at the top of the sedimentation cylinder, and a second valve body is installed at the bottom. One end of the juice conveying assembly is connected to the bottom of the vacuum tank. One end of the vacuum pumping assembly is connected to the top of the vacuum tank. One end of the nitrogen pumping assembly is connected to the top of the vacuum tank. One end of the juice discharging assembly is connected to the bottom of the vacuum tank and is located above the filter screen.
[0007] This utility model discloses a juice degassing device that uses sedimentation to remove impurities, eliminating the need to disassemble the filter screen inside the vacuum tank, thereby reducing the labor intensity of relevant personnel and improving the degassing efficiency of the juice.

[0019] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.
[0020] The juice degassing device of this utility model embodiment will now be described with reference to the accompanying drawings.
[0021] like Figure 1 and Figure 2 As shown, the juice degassing device of this utility model embodiment may include a vacuum tank 1, a sedimentation cylinder 2, a collection box 3, a juice conveying assembly 4, a vacuum pumping assembly 5, a nitrogen pumping assembly 6, and a juice discharge assembly 7.
[0022] The vacuum tank 1 has a filter screen 11 installed at the bottom of its inner side. One end of the sedimentation cylinder 2 is connected to the bottom of the vacuum tank 1, and the other end of the sedimentation cylinder 2 is connected to the collection box 3. A first valve body 20 is installed at the top of the sedimentation cylinder 2, and a second valve body 21 is installed at the bottom of the sedimentation cylinder 2.
[0023] Specifically, by setting the filter screen 11 at the bottom of the vacuum tank 1 and by also feeding the juice into the vacuum tank 1 from the bottom, impurities in the juice are intercepted (i.e., after a certain amount of juice is fed into the vacuum tank 1 at a time). The impurities fall off the filter screen 11 and settle at the bottom of the vacuum tank 1 and into the sedimentation cylinder 2. The controller (not shown in the figure) controls the opening and closing of the first valve body 20 and the second valve body 21 to discharge the impurities.
[0024] One end of the juice delivery assembly 4 is connected to the bottom of the vacuum tank 1.
[0025] It should be noted that one end of the juice delivery assembly 4 described in this embodiment is connected to the juice storage tank (not shown in the figure) via a pipe.
[0026] One end of the vacuum assembly 5 is connected to the top of the vacuum tank 1, one end of the nitrogen pump in assembly 6 is connected to the top of the vacuum tank 1, and one end of the juice discharge assembly 7 is connected to the bottom of the vacuum tank 1 and is located above the filter screen 11.
[0027] It should be noted that one end of the juice discharge component 7 described in this embodiment is connected to the filling pipe through a pipe, thereby facilitating the filling of deaerated juice.
[0028] Specifically, during actual operation, relevant personnel start the device and operate the controller to control the juice conveying component 4 to convey juice to the bottom of the vacuum tank 1. The juice conveyed into the vacuum tank 1 is filtered by the filter screen 11 and gradually reaches the specified juice conveying volume. After the conveying is completed, the juice conveying component 4 stops conveying, and the impurities on and at the bottom of the filter screen 11 begin to settle to the bottom of the vacuum tank 1 and into the sedimentation cylinder 2 (at this time, the first valve body 20 in the sedimentation cylinder 2 is open and the second valve body 21 is closed). The controller controls the vacuum pumping component 5 to operate, and the vacuum pumping component 5 extracts air from the vacuum tank 1 to form a vacuum, so that the gas in the juice is released and discharged from the vacuum pumping component 5 to the outside of the vacuum tank 1.
[0029] The controller controls the nitrogen pumping component 6 to operate, delivering nitrogen into the vacuum tank 1 to contact the negative pressure inside the vacuum tank 1, facilitating the discharge of degassed juice from the juice discharge component 7. In addition, nitrogen is insoluble in water and will not affect the juice. The controller controls the juice discharge component 7 to transport the degassed juice to the next process.
[0030] After the impurities in the sedimentation tank 2 (which can be made transparent) have settled, the relevant personnel operate the controller. The controller controls the first valve body 20 to close and the second valve body 21 to open, so that the impurities in the sedimentation tank 2 are discharged into the collection box 3 by gravity. This process is repeated to complete the degassing of the juice. This eliminates the need for frequent maintenance of the filter screen 11 and improves the degassing efficiency of the juice.
[0031] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the bottom plate 10 of the vacuum tank 1 is inclined, the filter screen 11 is inclined along with the bottom plate 10, and the sedimentation cylinder 2 is located at the bottom of the inclined bottom plate 10.
[0032] Specifically, the tilt of the bottom plate 10 allows the precipitated impurities to settle from the higher part of the bottom plate 10 to the lower part of the bottom plate 10, that is, to settle towards the sedimentation cylinder 2, thereby improving the collection efficiency of impurities. In addition, the tilt of the filter screen 11 can accelerate the falling of impurities from the filter screen 11, thereby further improving the collection efficiency of impurities.
[0033] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the juice delivery assembly 4 may include a pressurized delivery pump 40, a delivery pipe 41, and a check valve 42.
[0034] One end of the delivery pipe 41 is connected to the pressurized delivery pump 40, and the other end of the delivery pipe 41 is connected to the bottom of the vacuum tank 1. The check valve 42 is installed inside the delivery pipe 41.
[0035] Specifically, one end of the pressurized delivery pump 40 is connected to the juice storage tank via a pipe.
[0036] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the vacuum assembly 5 may include a vacuum pump 50 and a vacuum tube 51, wherein one end of the vacuum tube 51 is connected to the vacuum pump 50, and the other end of the vacuum tube 51 is connected to the top of the vacuum tank 1.
[0037] It should be noted that the vacuum pump 50 described in this embodiment can discharge the extracted gas to the outside of the vacuum tank 1. This technology is prior art and will not be described in detail here.
[0038] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the nitrogen pumping assembly 6 may include a nitrogen high-pressure container 60 and a pumping pipe 61, wherein one end of the pumping pipe 61 is connected to the nitrogen high-pressure container 60, and the other end of the pumping pipe 61 is connected to the top of the vacuum tank 1.
[0039] It should be noted that the nitrogen high-pressure container 60 described in this example is equipped with a nitrogen flow controller (not shown in the figure) to ensure the effective pumping of nitrogen.
[0040] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the juice discharge assembly 7 may include a discharge pipe 70 and a diaphragm pump 71, wherein one end of the discharge pipe 70 is connected to the diaphragm pump 71, and the other end of the discharge pipe 70 is connected to the bottom of the vacuum tank 1 and is located above the filter screen 11.
[0041] Understandably, the diaphragm pump 71 will not damage the juice.
[0042] Specifically, during actual operation, relevant personnel start the device and operate the controller to control the pressurized delivery pump 40 to deliver juice through the delivery pipe 41 to the bottom of the vacuum tank 1. The juice delivered to the vacuum tank 1 is filtered by the filter screen 11 and gradually reaches the specified juice delivery volume. After the delivery is completed, the pressurized delivery pump 40 stops delivering, and the impurities on and at the bottom of the filter screen 11 begin to settle at the bottom of the vacuum tank 1 and in the sedimentation cylinder 2 (at this time, the first valve body 20 in the sedimentation cylinder 2 is open and the second valve body 21 is closed). The controller controls the vacuum pump 50 to run and extracts air from the vacuum tank 1 through the vacuum pipe 51 to form a vacuum, so that the gas in the juice is released and discharged from the vacuum assembly 5 to the outside of the vacuum tank 1.
[0043] The controller controls the operation of the nitrogen high-pressure container 60, which delivers nitrogen into the vacuum tank 1 through the pump inlet pipe 61, thereby contacting the negative pressure inside the vacuum tank 1 and facilitating the discharge of degassed juice by the juice discharge component 7. In addition, nitrogen is insoluble in water and will not affect the juice. The controller controls the juice discharge component 7 to transport the degassed juice to the next process.
[0044] After the impurities in the sedimentation tank 2 (which can be made transparent) have settled, the relevant personnel operate the controller. The controller controls the first valve body 20 to close and the second valve body 21 to open, so that the impurities in the sedimentation tank 2 are discharged into the collection box 3 by gravity. This process is repeated to complete the degassing of the juice. This eliminates the need for frequent maintenance of the filter screen 11 and improves the degassing efficiency of the juice.
[0045] In summary, the juice degassing device of this utility model adopts a sedimentation method to remove impurities, eliminating the need to disassemble the filter screen inside the vacuum tank, thereby reducing the labor intensity of relevant personnel and improving the degassing efficiency of the juice.
