Description

Technical Field

[0001] This application relates to the technical field of food processing, and particularly to a high-pressure sterilization device and process for aseptic fresh-keeping juice. Background Art

[0002] Aseptic fresh-keeping juice is a kind of juice processed by special technology, aiming to extend its shelf life while maintaining the nutritional components and flavor of the juice. Aseptic fresh-keeping juice is widely used in supermarkets, the beverage industry, food service, etc. High-pressure sterilization (also known as autoclaving or high-pressure steam sterilization) is a method of sterilizing items using high-temperature and high-pressure steam, and is widely used in medical, food, and laboratory fields. The basic principle of high-pressure sterilization is to destroy the cell structure of microorganisms by increasing the temperature and pressure of the steam, so as to achieve the purpose of sterilization. High-pressure sterilization is an important process to ensure the safety of juice, extend its shelf life, maintain nutrition, and improve product quality.

[0003] For example, in the existing Chinese patent with the publication number CN107535792A, it discloses a high-temperature sterilization device for fruit juice beverages. Through the above-mentioned prior art, the fruit juice can be continuously sterilized, the efficiency of fruit juice disinfection and sterilization can be improved, and the fruit juice is indirectly heated and disinfected by high-temperature and high-pressure steam, so as to ensure that the nutritional components of the fruit juice are not damaged.

[0004] However, the above-mentioned prior art has the following technical defects: When the above-mentioned prior art is used, first, water is heated by a steam boiler to be converted into high-temperature and high-pressure steam. The steam enters the branch pipe through the inlet pipe, and finally the steam is discharged through the exhaust pipe. The fruit juice is input into the disinfection tank from the inlet pipe. The heat of the steam in the branch pipe is transferred to the fruit juice in the disinfection tank, so that the temperature of the fruit juice rises to play a role in disinfecting and sterilizing the fruit juice. The above device mainly transfers the heat of the steam flowing in multiple branch pipes in the disinfection tank to the fruit juice in the disinfection tank to achieve the purpose of disinfecting and sterilizing the fruit juice. However, since the position of the branch pipe is fixed, when the steam flows in the branch pipe, the heat transferred outward is limited. When the fruit juice flows into the disinfection tank, only the fruit juice around the branch pipe will have its temperature rise and can play a certain disinfection and sterilization effect. Only the local heating of the fruit juice is carried out, and the disinfection is not sufficient.

[0005] Secondly, since the position of the branch pipe is in the middle of the disinfection tank, after the fruit juice is input into the disinfection tank through the inlet pipe, the closer the fruit juice is to the branch pipe, the higher its temperature rises, while the temperature rise of the fruit juice at the bottom and both ends of the disinfection tank is lower. On the one hand, it will cause incomplete sterilization of the overall fruit juice entering the disinfection tank. On the other hand, the fruit juice in the middle of the disinfection tank will have too high a temperature, resulting in the disinfection and sterilization effect being difficult to meet the expectation.

[0006] Based on this, on the basis of an existing high-temperature sterilization device for fruit juice beverages, in order to overcome the above technical defects, there is still room for improvement. Summary of the Invention

Detailed implementation manners

[0038] The following will Figures 1 - 16 describe the present application in further detail with reference to the attached drawings.

[0039] The embodiment of the present application discloses a high-pressure sterilization device and process for sterile fresh-keeping juice, which can perform sufficient and effective high-pressure sterilization on the juice, and can immediately cool the juice after sterilization, reducing the loss of nutrients caused by high temperature and retaining the nutrients and flavor of the juice.

[0040] Embodiment 1: Referring to Figure 1 and Figure 2 As shown, on the first aspect, the present application provides a high-pressure sterilization device for sterile fresh-keeping juice, including a device base 1 and a steam generator 11 arranged on one side of the device base 1. It should be noted that the steam generator 11 is a device that heats water and converts it into steam, which is prior art and will not be elaborated here. A water storage tank 12 is arranged on one side of the steam generator 11, and a sterilization mechanism 2 cooperating with the steam generator 11 is arranged on the device base 1. Before use, appropriate amounts of water are added to the steam generator 11 and the water storage tank 12 respectively, and then the sterilization mechanism 2 can continuously perform high-temperature and high-pressure sterilization on the juice.

[0041] The sterilization mechanism 2 includes a sterilization barrel 22 installed on the device base 1 through an extension support 21. An air delivery pipe 23 connected to the sterilization barrel 22 is provided on the steam generator 11. When the steam generator 11 operates, the converted steam can be delivered into the sterilization barrel 22 through the air delivery pipe 23. The top and bottom of the sterilization barrel 22 are respectively inserted and installed with a liquid inlet pipe 24 and a liquid outlet pipe 25 extending into the barrel cavity. There are two sealing jacks 221 on the sterilization barrel 22 for installing the liquid inlet pipe 24 and the liquid outlet pipe 25. It should be noted that both the liquid inlet pipe 24 and the liquid outlet pipe 25 are fixedly and sealingly inserted and installed on the sterilization barrel 22. A shunt unit 3 is provided between the liquid inlet pipe 24 and the liquid outlet pipe 25 located inside the sterilization barrel 22; for shunting the fruit juice and increasing the time required for the fruit juice to flow from the liquid inlet pipe 24 to the liquid outlet pipe 25. A cooling unit 4 for cooling the sterilized fruit juice is provided on the water storage tank 12.

[0042] After adding appropriate amounts of water to the steam generator 11 and the water storage tank 12 respectively, then connect the pipeline through which the fruit juice flows to the outer end of the liquid inlet pipe 24, so that the fruit juice to be sterilized can be delivered into the sterilization barrel 22 through the liquid inlet pipe 24. When the fruit juice flows into the sterilization barrel 22, under the action of the shunt unit 3, the fruit juice will be shunted and the time for it to flow to the liquid outlet pipe 25 will increase, so that the steam delivered by the steam generator 11 into the sterilization barrel 22 can fully sterilize the shunted fruit juice. After the sterilization is completed, during the process of the fruit juice being discharged through the liquid outlet pipe 25, the cooling unit 4 can immediately cool down the fruit juice in a high-temperature state to reduce nutrient loss.

[0043] A pressure relief valve 13 is installed at the upper end of the sterilization barrel 22, and a water flow pipe 14 extending into the water storage tank 12 is provided at the lower end of the sterilization barrel 22, and a valve 15 is provided on the water flow pipe 14. When the pressure relief valve 13 and the valve 15 are closed, the sterilization barrel 22 is in a sealed state. After the sterilization of the fruit juice is completed, first open the pressure relief valve 13 to make the pressure in the sterilization barrel 22 return to the normal value. Then open the valve 15 to allow the steam water in the sterilization barrel 22 to flow into the water storage tank 12 through the water flow pipe 14 for recycling.

[0044] Refer to Figure 3As shown, specifically, the flow splitting unit 3 includes an upper connecting pipe 31 and a lower connecting pipe 32 that are respectively rotationally installed at the ends of the liquid inlet pipe 24 and the liquid outlet pipe 25 through two connecting members 5. In this embodiment, it is preferably that four spiral branch pipes 33 are communicatively arranged between the upper connecting pipe 31 and the lower connecting pipe 32. It should be noted that the two ends of the spiral branch pipes 33 are respectively fixedly connected and communicated with the ends of the upper connecting pipe 31 and the lower connecting pipe 32. At this time, the upper connecting pipe 31, the spiral branch pipes 33, and the lower connecting pipe 32 are integrally arranged. A driving assembly 6 for driving the lower connecting pipe 32 to rotate is provided at the inner walls of the lower connecting pipe 32 and the liquid outlet pipe 25. The operation of the driving assembly 6 can drive the lower connecting pipe 32 to rotate, that is, the upper connecting pipe 31 can be synchronously driven to rotate through the connection of the spiral branch pipes 33. The liquid inlet pipe 24, the upper connecting pipe 31, the spiral branch pipes 33, the lower connecting pipe 32, and the liquid outlet pipe 25 are all made of stainless steel. In this embodiment, it is preferably that the liquid inlet pipe 24, the upper connecting pipe 31, the spiral branch pipes 33, the lower connecting pipe 32, and the liquid outlet pipe 25 can be made of 304 or 316 stainless steel to ensure good heat conduction performance and good performance under high temperature and pressure.

[0045] After the fruit juice is transported to the sterilization barrel 22 through the liquid inlet pipe 24, it will first enter the upper connecting pipe 31, and then be split and enter the four spiral branch pipes 33. Due to the shape characteristics of the spiral branch pipes 33 and the decrease in pipe diameter, the time for the fruit juice to flow to the lower connecting pipe 32 and the liquid outlet pipe 25 will increase, thereby achieving the effect of increasing the flow time of the fruit juice in the sterilization barrel 22. At the same time, under the operation of the driving assembly 6, the upper connecting pipe 31, the four spiral branch pipes 33, and the lower connecting pipe 32 will continuously rotate slowly to facilitate the steam in the sterilization barrel 22 to fully perform high-temperature sterilization on the fruit juice in the spiral branch pipes 33.

[0046] Refer to Figures 4 to 6 As shown, in order to be able to rotationally install the upper connecting pipe 31 and the lower connecting pipe 32 at the ends of the liquid inlet pipe 24 and the liquid outlet pipe 25 located in the sterilization barrel 22 respectively, the connecting member 5 includes two main limiting rings 51 sleeved on the ends of the liquid inlet pipe 24 and the liquid outlet pipe 25 respectively, and the two main limiting rings 51 are respectively fixedly sleeved on the ends of the liquid inlet pipe 24 and the liquid outlet pipe 25; two secondary limiting rings 52 are respectively sleeved on the upper connecting pipe 31 and the lower connecting pipe 32, and the two secondary limiting rings 52 are respectively fixedly sleeved on the upper connecting pipe 31 and the lower connecting pipe 32; the main limiting ring 51 and the secondary limiting ring 52 are clamped and limited by an outer ring wheel one 53 and an outer ring wheel two 54, and the outer ring wheel one 53 and the outer ring wheel two 54 are respectively clamped on the main limiting ring 51 and the secondary limiting ring 52. During installation, the outer ring wheel one 53 and the outer ring wheel two 54 can be fixedly connected by means of sealed welding. To ensure that the fruit juice will not overflow, can smoothly flow into the four spiral branch pipes 33, and flow to the liquid outlet pipe 25 through the lower connecting pipe 32 after sterilization is completed.

[0047] Refer to Figures 7 to 9As shown in the figure, considering that the steam in the sterilization barrel 22 can fully and effectively sterilize the juice flowing in the spiral branch pipes 33 at high temperature, the multiple spiral branch pipes 33 can rotate continuously and slowly. The driving assembly 6 includes an internal gear ring 60 installed on the inner wall of the lower connecting pipe 32, and the internal gear ring 60 is fixedly connected to the inner wall of the lower connecting pipe 32; a guiding ring 61 is arranged above the internal gear ring 60, and the upper side of the guiding ring 61 has a certain inclination angle to ensure that the juice can flow smoothly into the liquid outlet pipe 25. A strip-shaped protective box 62 is arranged on the inner wall of the liquid outlet pipe 25, and the upper end of the strip-shaped protective box 62 extends into the lower connecting pipe 32. The strip-shaped protective box 62 has a rotating notch 621 for the guiding ring 61 and the internal gear ring 60 to pass through. An inner circular rod 63 is rotatably arranged in the strip-shaped protective box 62, and a transmission gear 64 meshing with the internal gear ring 60 is sleeved on the inner circular rod 63, and a transmission groove wheel 65 is sleeved at the bottom end of the inner circular rod 63.

[0048] When the transmission groove wheel 65 is driven by a driving force to drive the inner circular rod 63 to rotate, the lower connecting pipe 32 can be driven to rotate from the inside through the meshing of the transmission gear 64 and the internal gear ring 60. Furthermore, the upper connecting pipe 31, the four spiral branch pipes 33 and the lower connecting pipe 32 can be rotated in the sterilization barrel 22. So that the steam in the barrel can fully sterilize the juice in the spiral branch pipes 33 at high temperature.

[0049] Refer to Figure 10 and Figure 11 As shown in the figure, since it is necessary to avoid damaging the sealing performance of the sterilization barrel 22 during use, the inner circular rod 63 can be driven from the outside. A lifting cross bar 66 is clamped on the device seat 1, and a driving motor 67 is arranged on the lifting cross bar 66 on one side of the liquid outlet pipe 25. A driving groove wheel 68 is sleeved on the rotating shaft of the driving motor 67, and a transmission belt 69 is sleeved between the driving groove wheel 68 and the transmission groove wheel 65. An assembly port 251 communicating with the inner cavity of the strip-shaped protective box 62 and for installing the transmission belt 69 is opened on one side of the liquid outlet pipe 25.

[0050] Starting the driving motor 67 can drive the inner circular rod 63 to rotate continuously and slowly through the transmission belt 69. Since the strip-shaped protective box 62 is fixedly connected to the inner wall of the liquid outlet pipe 25, the juice will not enter the strip-shaped protective box 62. Although the strip-shaped protective box 62 is not fixedly connected to the inner wall of the lower connecting pipe 32, when the lower connecting pipe 32 is driven to rotate, it is inevitable that a small amount of juice adhering to the inner wall of the lower connecting pipe 32 will enter the strip-shaped protective box 62, but it will not affect the rotation of the lower connecting pipe 32.

[0051] Refer to Figure 12 and Figure 13As shown in the figure, in order to immediately cool the juice entering the liquid outlet pipe 25 with cold water spray after high-temperature sterilization of the juice and reduce the loss of nutrients caused by high temperature, the cooling unit 4 includes two spray boxes 42 symmetrically mounted on the water storage tank 12 through a rhombic bracket 41, and the two spray boxes 42 are buckled outside the liquid outlet pipe 25. The opposite sides of the two spray boxes 42 have arc-shaped inner walls 421, and a number of nozzles 43 are evenly distributed on the arc-shaped inner wall 421 of the spray box 42. It should be noted that there will be a certain gap at the bottom of the two spray boxes 42 even when they are buckled. So that the water sprayed by the nozzles 43 outside the liquid outlet pipe 25 can fall into the water storage tank 12.

[0052] Two water supply pumps 44 are respectively installed on both sides of the water storage tank 12. A water suction pipe 45 and a water supply pipe 46 communicating with the water storage tank 12 and the spray box 42 are respectively arranged on the water supply pumps 44. Starting the two water supply pumps 44 to operate can continuously transport the water in the water storage tank 12 to the spray box 42, and finally discharge and spray it outside the liquid outlet pipe 25 through a plurality of nozzles 43 inside the spray box 42. Thus, it is possible to cool the juice entering the liquid outlet pipe 25 after high-temperature sterilization and effectively reduce the loss of nutrients caused by high temperature.

[0053] Embodiment 2: Refer to Figure 14 and Figure 15 As shown in the figure, on the basis of Embodiment 1, in order to continuously and effectively cool the liquid outlet pipe 25, it is necessary to quickly cool the water that has risen in temperature after spraying and flows back into the water storage tank 12. A cooling component 7 is also provided on the water storage tank 12. The cooling component 7 includes plugging rings 71 sleeved on the liquid outlet pipe 25 and located at both ends of the spray box 42. Under the action of the two plugging rings 71, it can be ensured that the water after spraying will only fall into the water storage tank 12 through the gaps on the lower sides of the two spray boxes 42, and will not flow out from both ends of the spray box 42; A middle plate 72 is installed inside the water storage tank 12. A number of slow-flow strip plates 73 are inclined and distributed on one side of the middle plate 72. The slow-flow strip plates 73 are located directly below the two spray boxes 42. It should be noted that the slow-flow strip plates 73 are inclined and staggered and are installed on one side of the middle plate 72 in sequence from top to bottom, so that when the sprayed water falls, the time for the sprayed water to fall to the bottom of the water storage tank 12 can be extended.

[0054] A small air cooler 74 is clamped on the side wall of the water storage tank 12. The water storage tank 12 is provided with a clamping groove 121 for installing the small air cooler 74. When the small air cooler 74 is started, it can blow cold air towards the middle plate 72. Cooperating with a plurality of flow retarder plates 73 to delay the falling of the sprayed water, the temperature of the sprayed water can be effectively reduced, avoiding the overheating of the water in the water storage tank 12 caused by long-term repeated use. On the other hand, after sterilization is completed, open the valve 15 to drain the steam water in the sterilization barrel 22. After the steam water flows into the water storage tank 12 through the water pipe 14, it can also effectively cool the steam water discharged from the water pipe 14.

[0055] Referring Figure 16 As shown, on the other hand, the present application also discloses a high-pressure sterilization process for aseptic fresh-keeping juice, and the sterilization process includes the following steps: S1, Adding water and sending gas: Before use, add appropriate amounts of water to the steam generator 11 and the water storage tank 12 respectively. Connect the pipeline for transporting juice to the liquid inlet pipe 24, and start the steam generator 11 to heat the water into steam and send it into the sterilization barrel 22 through the gas transmission pipe 23. The steam in the sterilization barrel 22 can sterilize the juice shunted into the spiral branch pipes 33.

[0056] S2, Juice shunting: After the juice is transported to the sterilization barrel 22 through the liquid inlet pipe 24, under the action of the shunting unit 3, the juice will be shunted and slowly flow towards the liquid outlet pipe 25. After the juice is transported into the sterilization barrel 22, it is shunted into four spiral branch pipes 33 through the upper connection pipe 31, making the time for the juice to flow to the lower connection pipe 32 and the liquid outlet pipe 25 longer, achieving the purpose of increasing the flow time of the juice in the sterilization barrel 22.

[0057] S3, Full sterilization: Start the operation of the shunting unit 3 and cooperate with the steam in the sterilization barrel 22 to carry out full and effective sterilization of the juice. When the driving motor 67 operates, it can drive the inner circular rod 63 to rotate through the transmission belt 69. Under the meshing of the transmission gear 64 and the internal gear ring 60, the lower connection pipe 32 is driven to rotate from the inside, achieving the effect of rotating the four spiral branch pipes 33 in the sterilization barrel 22, so that the steam in the barrel can fully sterilize the juice in the spiral branch pipes 33.

[0058] S4, Rapid cooling: The sterilized juice is discharged outwards through the liquid outlet pipe 25. During the discharge process, the high-temperature sterilized juice is quickly cooled by the cooling unit 4 to reduce nutrient loss. Start the operation of the two water supply pumps 44 and the small air cooler 74. Driven by the water supply pump 44, the water in the water storage tank 12 will be transported to the spray box 42 and sprayed onto the outside of the liquid outlet pipe 25 through a plurality of nozzles 43 inside the spray box 42, thereby cooling the juice in the liquid outlet pipe 25. The cold air blown by the small air cooler 74 can effectively cool the sprayed water flowing back on the flow retarder plates 73.

[0059] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
