Description

Technical Field

[0001] This utility model relates to the technical field of baijiu brewing equipment, specifically to a cooling pool for the cooling process in baijiu brewing, which effectively improves the hygiene conditions during the cooling process and enhances the quality of the brewed liquor. Background Technology

[0002] In the cooling process of traditional baijiu brewing, the commonly used cooling tank is sunken below ground level, typically a square structure 9 meters long, 2 meters wide, and 0.7 meters deep. A perforated plate is installed at the top of the cooling tank, and a fan is installed on one side of the tank bottom. The air generated by the fan is blown through the perforated plate onto the mash, cooling the mash to meet process standards. However, during this process, moisture and smaller particles of mash fall through the perforations into the bottom of the cooling tank. These accumulated impurities are highly susceptible to spoilage and the growth of bacteria, contaminating the mash and severely affecting the quality of the brewed liquor. To ensure that the microbiological standards of brewing production meet the requirements, currently, it is necessary to manually move the perforated plate periodically and enter the cooling tank to remove the fallen impurities. However, manual cleaning is labor-intensive and difficult to guarantee timely and efficient cleaning, failing to meet the stringent hygiene and quality requirements of modern baijiu brewing. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a cooling pool for the cooling process in the brewing of baijiu (Chinese liquor).

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a cooling pool for the cooling process in baijiu brewing, comprising a cooling pool body located on the ground, a perforated plate for cooling on the top of the cooling pool body, a fan pit located on the ground in front of the cooling pool body, the fan pit being connected to the cooling pool body via a ventilation hole, a fan being installed in the fan pit, the fan's outlet being connected to the ventilation hole and blowing air towards the cooling pool body, and the cooling pool body being... The cooling pool is arranged in a rearward direction and has a V-shaped cross-section. The bottom of the cooling pool is sloped from front to back. Spray water pipes are horizontally arranged along the front-back direction on the top of the left and right slopes of the cooling pool. One end of the spray water pipe is connected to an external water source and the other end is sealed. The spray water pipe is connected to the external water source through a first water valve. Several spray holes are opened on the spray water pipes facing the corresponding slopes of the cooling pool below. The rear end of the bottom of the cooling pool is connected to a sewage channel through a sewage discharge channel.

[0005] Because the cooling pool is designed in a V-shape, debris falling into it will naturally slide down the sloping sides of the pool to the bottom under gravity, quickly collecting the debris for easy cleaning. Spray pipes are installed at the top of the sloping sides of the pool, with nozzles pointing towards the corresponding slope. When the first water valve is opened, connecting the spray pipes to an external water source, water sprays through the nozzles onto the sloping sides of the pool. The water flow, aided by gravity, washes the debris from the slope to the bottom, ensuring thorough cleaning. Furthermore, the pool bottom slopes from front to back, and the rear end of the pool bottom is connected to... The sewage discharge channel is connected to the sewage channel, so the debris collected at the bottom of the cooling tank can be automatically drawn to the rear of the cooling tank by the water flow and discharged into the sewage channel through the sewage discharge channel. This completes the cleaning of debris at the bottom of the cooling tank without the need for personnel to go down into the tank to clean the debris, greatly reducing the labor intensity of workers, improving cleaning efficiency, reducing labor costs, ensuring timely and efficient cleaning, greatly reducing the problem of microbial growth, significantly improving the level of microbial management, eliminating the problem of microbial contamination in the cooling process, meeting the strict requirements of modern baijiu brewing for hygiene and brewing quality, significantly improving the quality of fermented mash, thereby improving the quality of brewed liquor, which is conducive to increasing baijiu production and enhancing the company's market competitiveness.

[0006] Based on the above, the left and right sides of the cooling pool are covered with smooth stainless steel panels, which can avoid creating sanitary dead corners, make it easier for impurities to be washed away by the water flow, and facilitate the cleaning of impurities.

[0007] Based on the above, a spray pipe is pre-embedded at the bottom front of the cooling pool. The front end of the spray pipe is connected to an external water source, and the rear end faces the cooling pool body, with water exiting from there. The spray pipe is connected to the external water source via a second water valve. Therefore, during cleaning, opening the second water valve allows water to flow through the spray pipe, flushing debris collected at the bottom of the pool from the front to the rear, where it is ultimately discharged through the drainage channel, further improving the cleaning effect and preventing debris from accumulating at the bottom of the pool.

[0008] Based on the above, a check valve is installed in the sewage discharge channel to prevent sewage from flowing back into the cooling pool, which can effectively prevent sewage and odors from flowing back into the cooling pool and ensure the hygiene of the working environment of the cooling pool.

[0009] Based on the above, the sewage outlet of the sewage channel is hinged with a one-way outward opening blocking valve. The blocking valve vertically seals the sewage outlet of the sewage channel under gravity. The blocking valve only allows sewage to be discharged from the cooling pool and prevents sewage from flowing back into the cooling pool from the sewage channel.

[0010] Based on the above, a sewage collection tank, lower than the cooling pool body, is provided underground behind the cooling pool body. The sewage discharge channel connects the rear end of the cooling pool body's bottom to the sewage collection tank, and the sewage collection tank is connected to a sewage channel. Thus, the sewage collection tank can effectively collect sewage and debris, directing them to the sewage channel. Attached Figure Description

[0015] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0016] Example 1 like Figures 1-3 As shown, a cooling pool for the cooling process in baijiu brewing includes a cooling pool body 1 located on the ground. The top of the cooling pool body 1 has a perforated plate for cooling (not shown, a conventional setup). A fan pit 2 is also located on the ground in front of the cooling pool body 1. The fan pit 2 is connected to the cooling pool body 1 through a ventilation hole. A fan 3 is installed in the fan pit 2, and the air outlet of the fan 3 is connected to the ventilation hole and blows air towards the cooling pool body 1. The cooling pool body 1 is arranged along the front-to-back direction and has a V-shaped cross-section. Therefore, debris falling into the cooling pool body 1 will, under gravity, slope along both sides of the cooling pool body 1. The debris naturally slides to the bottom of the pool, quickly collecting the debris that falls into the cooling pool 1 at the bottom for easy collection and cleaning. The bottom of the cooling pool 1 is sloped, with the front higher than the back. Spray pipes 4 are horizontally arranged along the front-back direction on the top of the left and right slopes of the cooling pool 1. One end of each spray pipe 4 is connected to an external water source, and the other end is sealed. The spray pipe 4 is connected to the external water source through a first water valve (not shown). Several spray holes (not shown) are opened on the spray pipe 4 facing the corresponding slope of the cooling pool 1 below it. The rear end of the bottom of the cooling pool 1 is connected to the external sewage channel 5 through a sewage discharge channel.

[0017] In use, this invention simply requires periodically opening the first water valve to connect the spray pipe 4 to an external water source. The spray pipe 4 then sprays water through various nozzles onto the inclined surface of the cooling tank 1. The water flow, aided by gravity, washes debris from the inclined surface of the cooling tank 1 to the bottom, ensuring thorough cleaning. The debris collected at the bottom is then carried by the water flow to the rear of the cooling tank 1 and discharged into the sewage channel 5, completing the cleaning of the bottom of the cooling tank 1. Therefore, no personnel are required to enter the tank, significantly reducing labor intensity, improving cleaning efficiency, lowering labor costs, ensuring timely and efficient cleaning, and greatly reducing the risk of microbial growth. This significantly improves microbial management, eliminates microbial contamination during the cooling process, meets the stringent hygiene and brewing quality requirements of modern baijiu brewing, significantly improves the quality of fermented mash, and consequently enhances the quality of the brewed liquor, thus increasing baijiu production and strengthening the company's market competitiveness.

[0018] Example 2 like Figures 1-3 As shown, furthermore, the left and right sides of the cooling pool 1 are covered with smooth stainless steel panels (not shown in the figure), which can avoid creating sanitary dead corners, make it easier for impurities to be washed away by the water flow, and facilitate the cleaning of impurities.

[0019] Example 3 like Figures 1-3 As shown, furthermore, a spray pipe 6 is pre-embedded at the bottom front end of the cooling pool 1. The front end of the spray pipe 6 is connected to an external water source, and the rear end faces the cooling pool 1 to discharge water. The spray pipe 6 is connected to the external water source through a second water valve (not shown). Therefore, during cleaning, opening the second water valve allows water to flow through the spray pipe 6, which can flush the debris collected at the bottom of the pool from the front end to the rear end, and finally discharge it through the sewage channel, further improving the cleaning effect and preventing debris from accumulating at the bottom of the pool.

[0020] Example 4 like Figures 1-3 As shown, furthermore, a check valve 7 is installed in the sewage discharge channel to prevent sewage from flowing back from the sewage channel 5 into the cooling pool 1, which can effectively prevent sewage and odors from flowing back into the cooling pool 1 and ensure the hygiene of the working environment of the cooling pool 1.

[0021] Example 5 like Figures 1-3 As shown, further, a sewage collection tank 8 is provided underground behind the cooling pool body 1, which is lower than the cooling pool body 1. The sewage discharge channel connects the rear end of the bottom of the cooling pool body 1 and the sewage collection tank 8. The sewage collection tank 8 is connected to the sewage channel 5. The sewage collection tank 8 can effectively collect sewage and debris and direct the sewage and debris to the sewage channel 5.

[0022] In other embodiments, the sewage outlet of the sewage channel is hinged with an outwardly opening one-way blocking valve (not shown). The blocking valve vertically seals the sewage outlet of the sewage channel under gravity, allowing sewage only to drain from the cooling pool 1 and preventing sewage from flowing back into the cooling pool 1 from the sewage channel 5. Thus, the blocking valve can replace the check valve 7.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
