[0041] This utility model provides a liquid degassing and recovery device for degassing and recovering the liquid discharged from the material end 100 of the freezer for debugging equipment and product status. Under the premise of ensuring hygiene quality, the liquid can be reused for secondary freezing, thereby reducing liquid waste.

[0042] Specifically, such as Figure 1As shown, the liquid degassing and recovery device includes a heating unit 1, a degassing tank 2, an air breaker 3, a vacuum generator 4, and a storage tank 5. The discharge end 100 of the freezer is equipped with a discharge pipe 11 for discharging the liquid. The heating unit 1 is installed on the discharge pipe 11 to heat the discharged liquid. The purpose of heating is to reheat and melt the low-temperature viscous liquid, increase its fluidity, and facilitate recovery. The degassing tank 2 has a liquid inlet 21 and a liquid outlet 22. The liquid inlet 21 is connected to the discharge pipe 11 to receive the heated liquid. The air breaker 3 is located inside the degassing tank 2 and between the liquid inlet 21 and the liquid outlet 22, so that the liquid can pass through the air breaker 3 to discharge the gas. The vacuum generator 4 is connected to the degassing tank 2 through a vacuum pipe to maintain the negative pressure state of the degassing tank 2. The storage tank 5 has a liquid inlet 51 and a liquid outlet 52. A conveying pipe 23 is provided between the liquid outlet 22 and the liquid inlet 51 of the degassing tank 2. The degassed liquid enters the storage tank 5 through the conveying pipe 23. The liquid outlet 52 of the storage tank 5 is provided with a return pipe 53, which is connected to the discharge pipe 11 or the feed end 200 of the freezer.

[0043] The liquid degassing and recovery device provided by this utility model has a discharge pipe 11 installed at the discharge end 100 of the freezer. A heating unit 1 and a degassing tank 2 are installed on the discharge pipe 11. The degassing tank 2 and the storage tank 5 are connected by a conveying pipe 23. This device heats and degasses the liquid discharged from the freezer and stores it in the storage tank 5. By connecting the return pipe 53 to the discharge pipe 11, the liquid in the storage tank 5 can be circulated through the discharge pipe 11 for heating and degassing until it meets the feeding requirements of the freezer, and is finally stored in the storage tank 5. By connecting the return pipe 53 to the feeding end 200 of the freezer, the heated and degassed liquid can be supplied to the freezer again, realizing the recycling and reuse of the liquid, avoiding waste of liquid resources, and greatly saving ice cream production costs. In this embodiment, by setting a breaker 3 inside the degassing tank 2, the overflow of gas in the liquid can be increased. Under the negative pressure provided by the vacuum generator 4, the overflowing gas is continuously discharged from the degassing tank 2, which greatly increases the degassing speed and degassing efficiency of the liquid.

[0044] Preferably, the liquid inlet 21 is positioned higher than the liquid outlet 22, and the liquid inlet 51 is positioned higher than the liquid outlet 52.

[0045] In some embodiments, a first check valve 531 is provided on the return pipe 53, which is used to guide the liquid from the storage tank 5 to the degassing tank 2 in one direction.

[0046] The first one-way valve 531 ensures unidirectional flow of the liquid in the return pipe 53. Located at the front end of the heating unit 1, after the freezer or filling machine has resumed normal production, no more liquid is discharged, meaning the discharge end is closed. The liquid in the storage tank 5 can then undergo cyclic degassing. This unidirectional flow from the storage tank 5 to the degassing tank 2 forms a loop, preventing the liquid from flowing directly into the storage tank 5. The storage tank 5 is equipped with a temperature sensor to detect the liquid temperature and a conductivity meter to detect the liquid conductivity. It also has a stirrer 55 to adjust the temperature and gas content of the liquid to be as close as possible to or equal to the state before freezing, allowing the liquid in the storage tank 5 to be re-injected into the freezer for production, thus reducing waste.

[0047] It should be noted that a three-way control valve is used to connect the return pipe 53 and the discharge pipe 11 to facilitate switching control; similarly, a three-way control valve is used to connect the return pipe 53 and the feed end 200 of the freezer to facilitate switching control.

[0048] In some embodiments, the liquid degassing and recovery device further includes a first sanitary pump 231, which is disposed on the conveying pipe 23. The first sanitary pump 231 is configured to pump the liquid from the degassing tank 2 into the storage tank 5 to increase the discharge of the liquid from the degassing tank 2 and improve the degassing efficiency.

[0049] In some embodiments, the liquid degassing and recovery device further includes a second sanitary pump 532, which is disposed on the return pipe 53 and configured to pump the liquid from the storage tank 5 into the freezer or degassing tank 2. During the circulation heating and degassing process of the liquid between the storage tank 5 and the degassing tank 2, the second sanitary pump 532 provides circulation driving force for the liquid to ensure its circulation flow. When the liquid in the storage tank 5 meets the requirements of the freezer, the return pipe 53 is closed from the discharge pipe 11, and the second sanitary pump 532 is started to transport the liquid in the storage tank 5 to the feed end 200 of the freezer, realizing the recovery and reuse of the liquid.

[0050] In some embodiments, the liquid degassing and recovery device further includes a cyclone centrifuge, which is disposed inside the degassing tank 2 and located between the liquid inlet 21 and the air breaker 3.

[0051] The cyclone centrifuge is positioned close to the liquid inlet 21, allowing the liquid entering the deaeration tank 2 to directly fall onto the cyclone centrifuge for centrifugal dispersion, thereby increasing the overflow of gas from the liquid. The cyclone centrifuge can be a centrifuge or a cyclone fan, increasing the turbulence and centrifugal force of the liquid. The cyclone centrifuge is coaxially mounted with the deaeration tank 2, and the end of the exhaust pipe extends into the deaeration tank 2 and is located at the top of the cyclone centrifuge, ensuring the liquid and the centrifuge face each other for swirling exhaust. It should be noted that the deaeration tank 2 is equipped with a pressure sensor, and a vacuum generator 4 ensures a stable negative pressure environment within the deaeration tank 2. Air bubbles in the liquid will burst under negative pressure, causing gas to overflow, which is promptly removed by the vacuum generator 4, ensuring timely discharge of the overflowing gas.

[0052] In some embodiments, multiple air breaker 3s are provided, and the multiple air breaker 3s are arranged sequentially between the liquid inlet 21 and the liquid outlet 22.

[0053] like Figure 1 As shown, multiple air breaker 3 are connected in series along the axial direction inside the degassing tank 2 from the liquid inlet 21 to the liquid outlet 22. Under the action of the air breaker 3, the liquid material passing through the cyclone centrifuge first falls onto the air breaker 3, forming a very thin liquid film layer on the surface of the air breaker 3. The air bubbles in the liquid film layer are more easily broken and discharged, thereby improving the degassing efficiency. The liquid material passes through multiple air breaker 3 in sequence, undergoing multiple liquid film formation processes to ensure the degassing effect.

[0054] In some embodiments, the air breaker 3 is spherical. The spherical structure facilitates the formation of a liquid film layer, which in turn facilitates the rapid rupture and degassing of air bubbles within the liquid.

[0055] In some embodiments, a baffle 31 is provided between two adjacent air breaker 3, and the baffle 31 has an inner groove on the side facing the liquid inlet 21.

[0056] like Figure 2 As shown, the groove on the baffle 31 is a shallow, upward-curving groove. Under the action of the baffle 31, after the liquid passes through the air breaker 3, the state of the liquid film layer on the baffle 31 changes. The inner and outer layers of the liquid film layer randomly flip and flow along the edge of the groove to the next air breaker 3 to form a film, which is conducive to the filling and release of air bubbles in the liquid and improves the degassing efficiency. Generally, the outer diameter of the baffle 31 is smaller than the outer diameter of the air breaker 3, so that the liquid falling from the edge of the baffle 31 can continue to fall into the next air breaker 3, improving the degassing effect.

[0057] In some embodiments, the heating unit 1 includes an outer cylinder 12, a heating rod 13, a grid 14, and a baffle column 15. Both ends of the outer cylinder 12 are connected to a discharge pipe 11, so that the liquid in the discharge pipe 11 flows through the outer cylinder 12. The heating rod 13 is disposed inside the outer cylinder 12, and an annular fluid channel is formed between the heating rod 13 and the inner wall of the outer cylinder 12. The annular fluid channel is connected to the discharge pipe 11. The grid 14 is disposed inside the annular fluid channel and is connected to the outer wall of the heating rod 13. The baffle column 15 is disposed on the inner wall of the outer cylinder 12.

[0058] like Figure 3 and Figure 4 As shown, the heating rod 13 is located on the axis of the outer cylinder 12, and the two are coaxially arranged. Both ends of the outer cylinder 12 are connected to the discharge pipe 11. The heating rod 13 is connected to a power source for heating. When the liquid flows through the annular channel, it is radiated and heated by the heating rod 13, increasing its fluidity. A grid 14 and a turbulence column 15 are arranged inside the annular channel to increase the turbulence of the liquid, allowing the liquid to fully contact the heating rod 13. The grid 14 is set on the heating rod 13 to form a heat sink-like heating effect. The liquid is heated by contact with the grid 14, thereby increasing the melting speed of the liquid.

[0059] In some embodiments, the grilles 14 are provided in multiple groups, each group including multiple grid bars, the multiple grid bars being arranged circumferentially around the heating rod 13; the multiple grilles 14 are arranged axially spaced along the heating rod 13 and staggered circumferentially along the heating rod 13, and the baffle column 15 is provided between two groups of grilles 14.

[0060] like Figure 4 In the embodiment shown, two sets of grids 14 are arranged axially inside the outer cylinder 12. Multiple grid bars in each set of grids 14 extend axially, and the grid bars in the two sets of grids 14 are staggered along the circumference of the heating rod 13 to change the flow direction of the liquid. The outer diameter of the turbulence column 15 between the two sets of grids 14 is larger than the spacing between two adjacent grid bars in each set of grids 14, thereby increasing the contact heat exchange between the liquid and the grid bars.

[0061] Using the liquid degassing and water return device provided in this embodiment of the invention, during the start-up and commissioning of the freezer, the liquid is connected to the liquid degassing and recovery device of this invention. Specifically, the two ends of the discharge pipe 11 are connected to the discharge end 100 of the freezer and the liquid inlet 21 of the degassing tank 2. The liquid enters the inner cylinder of the degassing tank 2, and simultaneously, a motor drives a cyclone centrifuge to agitate the liquid, dispersing it and continuously passing it through multiple air breaker 3s. At the same time, a vacuum generator 4 creates negative pressure inside the degassing tank 2, causing the air bubbles in the liquid to burst and extracting the expanded gas. The liquid is then injected into the storage tank 5 under the action of gravity and the first sanitary pump 231. Once the freezer and filling machine are in normal operation, the liquid will no longer be discharged into the liquid degassing and recovery device. At this time, the return pipe 53 and the discharge pipe 11 can be connected, and the liquid in the storage tank 5 can be circulated and degassed until the liquid reaches the state before freezing. Then, the return pipe 53 can be connected to the feed end 200 of the freezer, and the degassed liquid can be reinjected into the feed end 200 of the freezer for production use, realizing the recycling and reuse of the liquid, thereby reducing the waste of liquid resources.

[0062] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
