Description

Technical Field

[0001] This utility model relates to the technical field of beverage cooling devices, specifically a rapid beverage cooling device based on a plate heat exchanger and an ice water system. Background Technology

[0002] Liquid beverages (such as those made by boiling water with large particles of chrysanthemum, honeysuckle, etc., to produce a cooling beverage) are widely consumed due to their sweet taste and energy-boosting properties. During production, these beverages require pasteurization. Pasteurization utilizes the fact that pathogens are not very heat-resistant, using appropriate temperatures and holding times to kill them completely. The resulting beverages are at a high temperature; without rapid cooling, their taste and quality will be severely affected. Furthermore, the high temperature environment easily breeds bacteria, causing secondary contamination. While some beverage cooling devices exist on the market, most suffer from low cooling efficiency and uneven cooling. Additionally, the presence of large particles in the beverage can easily clog cooling pipes during cooling, affecting the cooling effect and the lifespan of the device. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a rapid beverage cooling device based on a plate heat exchanger and an ice-water system, which solves the problem that beverages may contain large particulate impurities, which can easily clog cooling pipes during the cooling process.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a beverage rapid cooling device based on a plate heat exchanger and an ice water system, comprising an equipment box and an ice water system and a plate heat exchanger installed inside the equipment box. A storage box is also fixed to the inner wall of the equipment box, and a filter assembly is provided below the storage box. The output end of the filter assembly is connected to the beverage inlet end of the plate heat exchanger, and the filter assembly is used to filter the beverage in the storage box.

[0005] The filtration assembly includes a filter box located below the storage tank, a filter compartment inside the filter box, a filter cover fixed inside the filter compartment, and a drain pipe passing through the lower surface of the filter compartment, which is connected to the plate heat exchanger.

[0006] The above solution prevents large particles of impurities from entering the flow channels of the subsequent plate heat exchanger, avoids the risk of cooling pipe blockage, ensures the continuity and stability of the cooling process, protects the plate heat exchanger, and extends the service life of the equipment.

[0007] Furthermore, the filtration assembly also includes a pump fixed to the upper surface of the filter box. The storage box has a raw material hopper and a storage hopper inside. The input end of the pump passes through the raw material hopper, and the output end of the pump is fixed with a three-way valve. The three-way valve is installed on the lower surface of the filter box, and the output end of the three-way valve passes through the filter hopper. There are two filter hoppers, which are symmetrically arranged inside the filter box. The drain pipe is Y-shaped, and the inlet end of the drain pipe passes through the two filter hoppers respectively.

[0008] Through the above solution, the dual-filter chamber three-way valve enables simultaneous filtration and cleaning functions. When one filter chamber is performing normal filtration, the other filter chamber can be backwashed and cleaned without interrupting the entire cooling process, thus improving the equipment's working efficiency and continuity. The Y-shaped drain pipe allows the normally filtered beverage to enter the other filter chamber for backwashing.

[0009] Furthermore, a first drain pipe and a second drain pipe are respectively installed on the side of the filter chamber. A first control valve and a second control valve are respectively installed on the surface of the first drain pipe and the second drain pipe. The other end of the second drain pipe is connected to the first drain pipe. The first control valve is located at the middle position of the filter box and the intersection of the first drain pipe and the second drain pipe.

[0010] By adjusting the opening and closing of the first and second control valves, the filtered clean beverage flows backward through the filter cover, flushing up the impurities trapped on its surface and discharging them through the first and second drain pipes. This avoids the hassle of stopping and disassembling traditional equipment, reduces maintenance workload, and ensures the durability of the filtration effect.

[0011] Furthermore, the plate heat exchanger is used to cool the beverage in the raw material silo. The beverage output end of the plate heat exchanger is connected to the storage silo through a connecting pipe. Both the cold medium input end and the output end of the plate heat exchanger are connected to the ice water system.

[0012] Through the above scheme, the plate heat exchanger has a large specific surface area, which can realize rapid heat exchange between beverages and ice water. The ice water system provides a stable low-temperature cold source, ensuring that the beverage can be quickly cooled from the high temperature after pasteurization to the safe storage temperature, effectively preventing quality degradation and bacterial growth caused by slow cooling.

[0013] Furthermore, the disturbance component includes a motor fixed to the inner wall of the heat insulation cavity, a rotating rod fixed to the output end of the motor, and the other end of the rotating rod rotatably connected to the inner wall of the raw material hopper. A spiral stirring blade is fixed to the surface of the rotating rod. There are two rotating rods and two spiral stirring blades, which are symmetrically arranged inside the raw material hopper. A drive wheel is fixed to the surface of the rotating rod, and a driven wheel is connected to the drive wheel through a belt drive. The driven wheel is fixed to the surface of another rotating rod, and the two spiral stirring blades are in opposite directions.

[0014] The above solution uses agitation components to stir the undried beverage in the raw material hopper, preventing the sedimentation of large particles and ensuring a stable beverage concentration and uniform flow rate as it enters the filter chamber. This avoids excessive local pressure on the filter hood and frequent clogging. Simultaneously, it allows for a more uniform temperature and component distribution in the beverage, facilitating thorough and even heat exchange with the heat exchange plates. This not only prevents localized overheating that could degrade beverage quality but also reduces scaling on the heat exchange plate surface caused by uneven composition or excessive temperature.

[0015] Furthermore, a cover plate is rotatably mounted on the surface of the equipment box via a spiral spring. The position of the cover plate corresponds to the raw material bin and the storage bin. A fixing frame is also fixed on the lower surface of the storage bin, and the fixing frame is sleeved on the outer surface of the filter box.

[0016] The above solution not only facilitates the addition of raw materials and the removal of finished products by using a spiral spring, making operation simple, but also helps maintain the hygiene of the storage box and prevents external contaminants from entering.

[0017] Compared with the prior art, the technical solution of this utility model has the following beneficial effects: I. This rapid beverage cooling device based on a plate heat exchanger and ice water system intercepts large particulate impurities in the beverage by setting up a filter cover, preventing them from entering the plate heat exchanger and causing blockage, ensuring a smooth cooling process and extending the service life of the equipment. At the same time, the dual filter chambers and three-way valve allow filtration and cleaning to be carried out simultaneously. When one filter chamber is working normally, the other can be backwashed, and cleaning can be completed without stopping the machine, improving the efficiency and continuity of the equipment.

[0018] Second, this beverage rapid cooling device based on a plate heat exchanger and ice water system, by setting up a disturbance component, not only prevents the precipitation of impurities in the beverage and ensures the stability of the beverage concentration and flow rate entering the filter box, but also makes the temperature and component distribution of the beverage more uniform during the heat exchange process, avoiding the quality degradation caused by local overheating and reducing the scaling phenomenon on the surface of the heat exchange plates.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Please see Figure 1-6This embodiment discloses a rapid beverage cooling device based on a plate heat exchanger 3 and an ice water system 2. The device includes an equipment housing 1 and an ice water system 2 and a plate heat exchanger 3 installed inside the equipment housing 1. A storage tank 4 is also fixed to the inner wall of the equipment housing 1. A filter assembly 5 is installed below the storage tank 4. The output end of the filter assembly 5 is connected to the beverage inlet of the plate heat exchanger 3. The filter assembly 5 is used to filter the beverage in the storage tank 4. The filter assembly 5 includes a filter box 501 located below the storage tank 4. A filter chamber 505 is opened inside the filter box 501. A filter cover 506 is fixed inside the filter chamber 505. A drain pipe 507 passes through the lower surface of the filter chamber 505 and is connected to the plate heat exchanger 3. The filter cover 506 prevents large particles of impurities from entering the subsequent flow channel of the plate heat exchanger 3, avoiding the risk of cooling pipe blockage, ensuring the continuity and stability of the cooling process, protecting the plate heat exchanger 3, and extending the service life of the equipment.

[0023] Please see Figure 2 , Figure 3 and Figure 4 The filter assembly 5 also includes a pump 503 fixed to the upper surface of the filter box 501. The storage box 4 has a raw material hopper 401 and a storage hopper 402 inside. The input end of the pump 503 passes through the raw material hopper 401, and a three-way valve 504 is fixed to the output end of the pump 503. The three-way valve 504 is installed on the lower surface of the filter box 501, and its output end passes through the filter chamber 505. There are two filter chambers 505, symmetrically arranged inside the filter box 501. The drain pipe 507 is Y-shaped, with its inlet end passing through both filter chambers 505. The dual filter chambers 505 and the three-way valve 504 enable simultaneous filtration and cleaning. When one filter chamber 505 is performing normal filtration, the other filter chamber 505 can be backwashed for cleaning without interrupting the entire cooling process, improving the equipment's efficiency and continuity. Water pipe 507 allows the normally filtered beverage to enter another filter chamber 505 for backwashing. A first drain pipe 508 and a second drain pipe 510 are respectively installed on the side of the filter chamber 505. A first control valve 509 and a second control valve 511 are respectively installed on the surface of the first drain pipe 508 and the second drain pipe 510. The other end of the second drain pipe 510 is connected to the first drain pipe 508. The first control valve 509 is located in the middle of the intersection of the filter box 501 and the first drain pipe 508-second drain pipe 510. By adjusting the opening and closing of the first control valve 509 and the second control valve 511, the filtered clean beverage flows back through the filter cover 506, flushing up the impurities trapped on its surface and discharging them through the first drain pipe 508 and the second drain pipe 510. This avoids the trouble of stopping and disassembling traditional equipment, reduces maintenance workload, and ensures the durability of the filtration effect.

[0024] Please see Figure 2 , Figure 3 and Figure 4 The plate heat exchanger 3 is used to cool the beverage in the raw material silo 401. The beverage output end of the plate heat exchanger 3 is connected to the storage silo 402 through a connecting pipe. The cold medium input end and output end of the plate heat exchanger 3 are both connected to the ice water system 2. The plate heat exchanger 3 has a large specific surface area, which can realize rapid heat exchange between the beverage and the ice water. The ice water system 2 provides a stable low temperature cold source to ensure that the beverage can be quickly cooled from the high temperature after pasteurization to the safe storage temperature, effectively preventing quality degradation and bacterial growth caused by slow cooling.

[0025] Please see Figure 5 and Figure 6 The disturbance component 6 includes a motor 601 fixed to the inner wall of the insulation cavity 403. A rotating rod 602 is fixed to the output end of the motor 601. The other end of the rotating rod 602 is rotatably connected to the inner wall of the raw material hopper 401. A spiral stirring blade 603 is fixed to the surface of the rotating rod 602. There are two rotating rods 602 and two spiral stirring blades 603, symmetrically arranged inside the raw material hopper 401. A drive wheel 604 is fixed to the surface of the rotating rod 602. The drive wheel 604 is connected to a driven wheel 605 via a belt drive. The driven wheel 605 is fixed to the surface of another rotating rod 602. The spiral stirring blades 603 move in opposite directions, stirring the uncold beverage in the raw material bin 401 through the agitation component 6. This prevents large particles of impurities from settling, ensuring a stable beverage concentration and uniform flow rate as it enters the filter box 501. This avoids excessive local pressure in the filter cover 506, which can cause frequent clogging. At the same time, it also makes the temperature and composition of the beverage more uniform, allowing for thorough and even heat exchange with the heat exchange plates. This not only prevents the beverage quality from deteriorating due to local overheating but also reduces scaling on the surface of the heat exchange plates caused by uneven composition or excessive temperature.

[0026] Please see Figure 1 , Figure 2 and Figure 3 A cover plate 101 is rotatably mounted on the surface of the equipment box 1 via a spiral spring. The position of the cover plate 101 corresponds to that of the raw material bin 401 and the storage bin 402. A fixing bracket 502 is also fixed to the lower surface of the storage bin 4. The fixing bracket 502 is sleeved on the outer surface of the filter box 501. The cover plate 101, which is mounted via a spiral spring, not only facilitates the addition of raw materials and the removal of finished products, making operation simple, but also helps to maintain the hygienic conditions inside the storage bin 4 and prevent external contaminants from entering. It should be noted that by setting up the filter cover 506 to intercept large particulate impurities in the beverage, large particles are prevented from entering the plate heat exchanger 3 and causing blockage, ensuring the smooth operation of the cooling process and extending the service life of the equipment. At the same time, the dual filter chambers 505 and the three-way valve 504 allow filtration and cleaning to be carried out simultaneously. When one filter chamber 505 is working normally, the other can be backwashed, and cleaning can be completed without stopping the machine, improving the efficiency and continuity of the equipment.

[0027] In addition, by setting the disturbance component 6, not only is the sedimentation of impurities in the beverage prevented, ensuring the stability of the beverage concentration and flow rate entering the filter box 501, but also the temperature and component distribution of the beverage are more uniform during the heat exchange process, avoiding quality degradation caused by local overheating and reducing scaling on the surface of the heat exchange plates.

[0028] The working principle of the above embodiments is as follows: First, the device is placed in a suitable location and connected to an external power source and control equipment. The control equipment includes known conventional devices such as controllers and computers with control functions. Then, the operator opens the cover 101 and pours the uncooled beverage into the raw material silo 401. The operator then controls the ice water system 2 via the control equipment, causing the low-temperature cold water to flow in the plate heat exchanger 3. Next, the operator controls the pump 503 via the control equipment, injecting the beverage from the raw material silo 401 into one of the filter chambers 505 through a three-way valve 504. The beverage is then filtered through a filter cover 506. The filtered beverage enters the plate heat exchanger 3 through a drain pipe 507, where it exchanges heat with the low-temperature cold water before entering the storage chamber 402 through a connecting pipe. During the filtration process, the operator controls the first control valve 509 and the second control valve 511 to close, preventing the beverage from being discharged through the first drain pipe 508 and the second drain pipe 510, thus avoiding waste.

[0029] When the filter cover 506 needs cleaning, the operator uses the control device to control the three-way valve 504 to inject unfiltered beverage into another filter chamber 505 that does not need cleaning. Then, the operator controls the first control valve 509 to open, at which point the first drain pipe 508 and the filter chamber 505 are connected. When the filtered beverage is discharged from the Y-shaped drain pipe 507, it can enter the filter chamber 505 that needs cleaning, thereby rinsing the filter cover 506 from the inside. The impurities washed off are discharged through the first drain pipe 508. Similarly, when cleaning the filter cover 506 on the other side, the operator simply controls the first control valve 509 to close and the second control valve 511 to open, connecting the second drain pipe 510 to the first drain pipe 508. The operator then adjusts the three-way valve 504 to allow the beverage to enter the filter chamber 505 that does not need cleaning. The beverage enters the filter chamber 505 from the Y-shaped drain pipe 507, thereby cleaning the filter cover 506 from the inside. The impurities washed off are discharged through the second drain pipe 510.

[0030] During the beverage cooling process, motor 601 starts synchronously, driving rotating rod 602 and spiral stirring blade 603 to rotate. Drive wheel 604 drives driven wheel 605 via belt, causing both rotating rods 602 and spiral stirring blade 603 to simultaneously stir the beverage in raw material hopper 401. This prevents large particles from settling, ensures stable beverage concentration and uniform flow rate entering filter box 501, improves filtration efficiency, and prevents filter cover 506 from clogging. Simultaneously, stirring makes the beverage temperature and component distribution more uniform, allowing for thorough and even heat exchange with the heat exchange plates of plate heat exchanger 3, improving cooling efficiency, reducing scaling on the heat exchange plate surface, and extending the device's service life.
