Description

Technical fields:

[0001] This utility model relates to the field of brewing equipment technology, and specifically to a wine cooler with a fan system that increases the yield of qualified wine while ensuring the quality of the wine. Background technology:

[0002] Brewing is the process of producing alcoholic beverages with a certain concentration through microbial fermentation. Raw materials and brewing containers are two prerequisites for grain-based brewing. Baijiu, a distilled spirit made primarily from grains, using daqu, xiaoqu, or bran koji and yeast as saccharifying and fermenting agents, is produced through cooking, saccharification, fermentation, and distillation. It is also known as shaojiu, laobaigan, and shaodaozi.

[0003] The applicant has proposed a heat recovery type wine cooler (authorization announcement number CN215757239U), which includes a heat exchange device. This heat exchange device comprises a shell and a heat exchange core assembly installed within the shell. The heat exchange core assembly has a plate-side flow channel inside, and a shell-side flow channel is formed between the heat exchange core assembly and the shell, isolated from the plate-side flow channel. The upper and lower ends of the shell have wine vapor inlets and wine outlets respectively, communicating with the shell-side flow channels. The outer side of the shell has a cooling water inlet and a hot water outlet, communicating with the plate-side flow channels. The hot water outlet is connected to a heat recovery module. The lower end of the shell has a downward-protruding, funnel-shaped shell, wider at the top and narrower at the bottom, with the wine outlet located at the lower end of the funnel-shaped shell. The aforementioned heat recovery type wine cooler has a simple structure, is easy to install, and possesses strong market competitiveness.

[0004] However, the applicant discovered some shortcomings in the aforementioned heat recovery wine cooler during use: When wine vapor passes through the shell-side flow channel and exchanges heat with the cold water in the plate-side flow channel, cooling the wine vapor to form wine liquid, and then flowing out from the wine liquid outlet, a small amount of wine liquid adheres to the inner wall of the shell-side flow channel. After a period of time, this wine liquid forms a milky white liquid. As a result, when wine vapor is introduced again, the wine liquid formed by the condensation of the wine vapor will mix with this milky white liquid, causing the initially flowing wine liquid to be cloudy, affecting the quality of the wine. Therefore, this cloudy wine liquid is considered unqualified until the wine liquid flowing out of the wine cooler is no longer cloudy, which leads to a significant waste of wine liquid, resulting in a low yield and affecting the quality of the wine liquid.

[0005] In view of this, the inventors have made further improvements to the above-mentioned heat recovery wine cooler, in order to propose a wine cooler with a fan system that increases the output of qualified wine and ensures the quality of the wine. Utility Model Content:

[0014] Furthermore, in the above technical solution, the steam cleaning pipe is also sealed to the housing structure through a second flared structure.

[0015] Furthermore, in the above technical solution, the heat exchange core assembly includes a primary heat exchange core, a secondary heat exchange core, and a tertiary heat exchange core installed sequentially from top to bottom within the outer casing.

[0023] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0024] See Figure 1-5 The image shows a wine cooler with a fan system, comprising a heat exchange device 100. The heat exchange device 100 includes a housing 1 and a heat exchange core assembly 2 installed inside the housing 1. The heat exchange core assembly 2 has a plate-side flow channel inside, and a shell-side flow channel is formed between the heat exchange core assembly 2 and the housing 1, which is isolated from the plate-side flow channel. The housing 1 is provided with a wine vapor inlet pipe 11 and a wine liquid outlet pipe 12 that connect to the shell-side flow channel. In actual use, wine vapor is introduced into the wine vapor inlet pipe 11, and the wine vapor enters the shell-side flow channel and exchanges heat with the cooling water flowing in the shell-side flow channel, thereby condensing the wine vapor and finally forming wine liquid. This wine liquid flows out through the wine liquid outlet pipe 12, thereby realizing winemaking. The above technology is conventional technology in this field.

[0025] The main improvements of this utility model are as follows: This utility model also includes a fan system 3, which includes a fan 31 and an air outlet pipe 32 connected to the fan 31. The air outlet pipe 32 is connected to the liquor outlet pipe 12, and a first control valve 321 is also provided on the air outlet pipe 32. A second control valve 121 is provided on the liquor outlet pipe 12. When the liquor outlet pipe 12 is closed by the second control valve 121, and the first control valve 321 is opened to connect the air outlet pipe 32 to the liquor outlet pipe 12, the air generated by the fan 31 flows through the air outlet pipe 321. 2. The liquid is fed into the outlet pipe 12 and enters the shell-side flow channel to remove residual liquid in the shell-side flow channel. That is, by air drying, no liquid remains in the shell-side flow channel. In this way, when the alcohol vapor is introduced again, the alcohol vapor condenses and the resulting liquid will not mix with the residual milky white liquid as described in the background art (because this utility model does not produce / residue milky white liquid). This ensures that the initially flowing liquid is clear, thus guaranteeing the quality of the liquid. In other words, such liquid is considered a substandard product, achieving a high yield of alcohol. This utility model condenses and forms a large quantity of liquid while ensuring the quality of the liquid.

[0026] To ensure that the air generated by the fan 31 is cleaner, the following design is also made: a filter 34 is provided at the end of the air inlet pipe 33 of the fan 31. That is, when the fan system 3 is in use, the outside air is drawn in through the air inlet pipe 33 to form a high-speed airflow. At this time, the filter 34 filters out dust and other gaseous substances carried in the air, making the air entering the air inlet pipe 33 cleaner. This ensures that the high-speed air entering the shell-side flow channel will not contaminate the shell-side flow channel during the drying process, thus ensuring the cleanliness of the shell-side flow channel and resulting in higher quality wine formed when the wine vapor is condensed later.

[0027] In this embodiment, the first control valve 321 is an electrically operated ball valve. This electrically operated ball valve is an industrial valve used for diverting, merging, or switching the flow direction of pipeline media. It features pressure resistance, temperature resistance, corrosion resistance, and low flow resistance. The valve is driven by an electric actuator, which facilitates automated control.

[0028] In this embodiment, the fan 31 is a vortex fan, which is a high-pressure fluid control device. This device has both blowing and suction functions, supports oil-free operation, and outputs clean air.

[0029] In this embodiment, the heat exchange device 100 is installed inside the housing 4, and the housing 4 protects the heat exchange device 100. The housing 4 is a vertical cylindrical shape, or it can be considered as a capsule shape, which can minimize the overall volume of the product for easy transportation and installation. The wine vapor inlet pipe 11 and the wine outlet pipe 12 both extend outside the housing 4, which facilitates installation and use.

[0030] In this embodiment, the housing 4 is mounted on the bracket 5 for support and is fixed to the floor, making it more convenient to use. The bracket 5 contains a support mesh plate 51. The fan 31 is mounted on the support mesh plate 51 and located below the housing 4. Using the support mesh plate 51 to support and mount the fan 31 facilitates heat dissipation and improves the working quality of the fan 31.

[0031] In addition, to better protect the fan 31, the following design was made: a protective cover 52 is also provided on the support mesh plate 51, which covers the fan 31 to better protect it and prevent it from being exposed and damaged by collisions with other objects. Furthermore, a gap is formed between the upper end of the protective cover 52 and the lower end of the casing 4; the end of the air outlet pipe 32 passes through this gap to extend beyond the protective cover 52 and connects to the wine outlet pipe 12.

[0032] A control box 41 is provided on the housing 4. The rear end of the control box 41 is embedded inside the housing 4. A heat insulation plate 13 is welded and fixed to the inner wall of the housing 4. The heat insulation plate 13 divides the inner cavity of the housing 4 into a main chamber 401 and a heat insulation chamber 402 that are isolated from each other. The heat exchange core group 2 is placed in the main chamber 401. The rear end of the control box 41 is exposed in the heat insulation chamber 402. That is, the heat generated by the heat exchange core group 2 during operation will not be directly transferred to the control box 41 in the heat insulation chamber 402, so that the control box 41 does not work in a high-temperature environment, thus ensuring the working quality and service life of the control box 41.

[0033] The casing 4 is also equipped with a steam cleaning pipe 43. After a period of use, when the shell-side flow channel needs cleaning, the upper end of the steam cleaning pipe 43 is passed through the upper end of the casing 4 and connected to the wine steam inlet pipe 11 via a first flared structure 44, forming a sealed, detachable assembly. The steam cleaning pipe 43 is also equipped with a steam flushing switch valve 45 to control its on / off state. The lower end of the steam cleaning pipe 43 is connected to a clean steam source. After opening the steam flushing switch valve 45, the clean steam source supplies clean steam to the steam cleaning pipe 43, which then enters the shell-side flow channel to flush and clean it, thus improving the quality of subsequent winemaking. Furthermore, the blower system 3 further dries the shell-side flow channel to ensure no liquid residue remains, significantly improving the quality of winemaking after the next steam injection. When the steam flushing function is not needed, the first flared structure 44 can be detached from the wine steam inlet pipe 11.

[0034] The steam cleaning pipe 43 is also sealed to the housing 4 through the second flared structure 46, thereby preventing external dust and other substances from entering the inner wall of the housing 4 and achieving a protective function.

[0035] The utility model relates to large-scale equipment. To facilitate the maintenance of the utility model by working staff, the following design is further provided: a ladder frame shaped like a Chinese character "ri" or a Chinese character "mu" is provided at the outer middle part or middle-upper part of the support 5, a handrail 42 is provided on the outer side of the casing 4, and the handrail 42 is located above the ladder frame 53. The ladder frame 53 and the handrail 42 facilitate working staff to climb, so as to perform maintenance on the utility model.

[0036] The heat exchange core assembly 2 comprises a first-stage heat exchange core 21, a second-stage heat exchange core 22 and a third-stage heat exchange core 23 which are sequentially installed in the outer shell 1 from top to bottom. A first shell-side flow channel 211, a second shell-side flow channel 221 and a third shell-side flow channel 231 are respectively formed between the first-stage heat exchange core 21, the second-stage heat exchange core 22, the third-stage heat exchange core 23 and the outer shell 1. The first shell-side flow channel 211, the second shell-side flow channel 221 and the third shell-side flow channel 231 communicate with each other to form the shell-side flow channel; temperature sensors 201 are respectively arranged at inlets of the first shell-side flow channel 211, the second shell-side flow channel 221 and the third shell-side flow channel 231, so as to detect the temperature of the formed wine liquid in each shell-side flow channel, which facilitates subsequent control of the flow rate of cooling water in each plate-side process, so as to control the temperature of the wine liquid in each shell-side flow channel and ensure the quality of the discharged wine in the later stage.

[0037] A first plate-side flow channel 212, a second plate-side flow channel 222 and a third plate-side flow channel 223 are respectively arranged inside the first-stage heat exchange core 21, the second-stage heat exchange core 22 and the third-stage heat exchange core 23. The first plate-side flow channel 212, the second plate-side flow channel 222 and the third plate-side flow channel 223 are combined to form the plate-side flow channel; the wine steam inlet pipe 11 is located above and communicates with the first shell-side flow channel 211.

[0038] A first cooling water inlet pipe 14 and a hot water heat recovery outlet pipe 15 that communicate with the plate-side flow channel are arranged outside the outer shell 1. The first cooling water inlet pipe 14 and the heat recovery outlet pipe 15 are respectively connected to two ends of the first plate-side flow channel 212, and the heat recovery outlet pipe 15 is connected to a heat recovery module; that is, the utility model only recovers the heat of the first-stage heat exchange core 21, which performs heat exchange on wine steam first, and the heat of the first-stage heat exchange core 21 is the highest. That is, the high-temperature cooling water formed after heat exchange is recovered through the heat recovery outlet pipe 15, the high-temperature cooling water is recovered to the heat recovery module and recycled by the heat recovery module, so as to achieve the purpose of energy conservation and environmental protection.

[0039] In addition, the first cooling water inlet pipe 14 is provided with a first electric switch type ball valve 141; the flow of inlet cooling water can be controlled through the first electric switch type ball valve 141, so as to adjust the heat exchange efficiency and capacity, and further control the temperature of the cooled wine liquid.

[0040] The third shell-side flow channel 231 is connected to the second cooling water inlet pipe 24. The second shell-side flow channel 221 and the third shell-side flow channel 231 are connected by the first connecting pipe 25. The second shell-side flow channel 221 is connected to the cooling water outlet pipe 26. The first plate-side flow channel 212 is not three-dimensional with the second shell-side flow channel 221 and the third shell-side flow channel 231. It is an independent plate-side flow channel with the highest heat exchange efficiency.

[0041] The second cooling water inlet pipe 24 is also connected to an emergency water inlet pipe 242, which is equipped with a third control valve 243 for controlling on / off switching. The cooling water outlet pipe 26 is also connected to an emergency water outlet pipe 261, which is equipped with a fourth control valve 262 for controlling on / off switching. The cooling water outlet pipe 26 is connected to a second connecting pipe 263, which is connected to the second cooling water inlet pipe 24 via an electric three-way regulating valve 264. The electric three-way regulating valve 264 regulates the pressure of the liquid flow in the second shell-side flow channel 221 and the third shell-side flow channel 231, thereby controlling the heat exchange efficiency and thus regulating the temperature of the wine at each stage. The electric three-way regulating valve is an Oventrop electric three-way regulating valve. This invention adds an emergency water inlet pipe 242 and a third control valve 243 to enable emergency water intake and ensure normal operation. It also adds a cooling water outlet pipe 26 and a fourth control valve 262 to enable emergency water discharge and ensure normal operation. Under normal conditions, both the third control valve 243 and the fourth control valve 262 are closed.

[0042] In summary, this utility model adds a fan system 3. When the utility model does not condense the alcohol vapor, the fan system 3, when the second control valve 121 closes the alcohol outlet pipe 12 and the first control valve 321 is opened to connect the air outlet pipe 32 to the alcohol outlet pipe 12, the air generated by the fan 31 is input to the alcohol outlet pipe 12 through the air outlet pipe 32 and enters the shell-side flow channel to remove residual liquid in the shell-side flow channel. That is, by air drying, no liquid remains in the shell-side flow channel. In this way, when alcohol vapor is introduced again, the alcohol vapor condensed into alcohol liquid will not be mixed with the residual milky white alcohol liquid described in the background art. The alcohol liquid that flows out at the beginning is clear, ensuring the quality of the alcohol liquid. That is, these alcohol liquids are considered unqualified products, achieving a high alcohol yield. This utility model condenses a large quantity of alcohol liquid while ensuring the quality of the alcohol liquid.

[0043] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model.
