Description

Technical Field

[0001] The invention relates to drinking water technology, in particular to a method for producing aged water. Background Art

[0002] With the progress of society, people's living standards have greatly improved, but social development is also accompanied by many unscientific behaviors that cause environmental pollution. Environmental pollution has also brought a lot of pollution to our drinking water. As people's living standards improve, they pay more and more attention to health, and as the source of life, water is even more important. The importance of drinking water to people is self-evident. How to let everyone drink healthy water is the key! Drinking boiled water-commonly known as hot water is very beneficial to human health. The accelerated pace of life makes people want to get good water anytime and anywhere. As a processed and packaged old boiled water-old fire water is a good choice. Summary of the invention

[0003] The purpose of the present invention is to provide a method for producing aged water in view of the shortcomings of the prior art. The method is scientific and environmentally friendly, easy to operate, and the aged water produced is hygienic, clean, beneficial to the human body, and convenient to drink.

[0004] The technical solution for achieving the purpose of the present invention is: A method for producing aged water comprises the following steps: 1) Primary filtration: The source water passes through the first filtration equipment to filter out the granular sand and debris, and the filtered water enters the first water tank for standby use; 2) Second filtration: The water in the first water tank is filtered for the second time. The second filtration uses quartz sand filtration, activated carbon filtration, microporous filtration, and ultra-microporous filtration in sequence to obtain purified water, which is then fed into the second water tank for standby use. 3) First water boiling: Heat the clean water in the second water tank to above 99°C within 5 seconds using heat energy exchange to make cooked water; 4) Second boiling: The cooked water after the first boiling is sent into the steam stew pot to maintain a water temperature of not less than 99°C, and is kept above 99°C under a standard atmospheric pressure for 0.5-168 hours to make old cooked water; 5) Thermal cycle: The cooked water in the steam stew pot is sent to the cooling water circulation system with cooling function to obtain cooled cooked water; 6) Re-filtration: Cool the aged water and filter it through nitrite filtration and precision filtration; 7) Sterilization: Step 6) The filtered aged water is sterilized by ultraviolet light and sent to the ozone mixing device; 8) Finished product packaging: The water output from the ozone mixing device is a finished drinking aged water product that has undergone secondary steaming and is ready for packaging.

[0005] The stewing time in step 4) is 7 hours, at which time the taste is best.

[0006] The water that completes all the above production process is called aged water.

[0007] This method is scientific, environmentally friendly, easy to operate, and the produced aged water is hygienic, clean, beneficial to the human body, and easy to drink. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0010] The content of the present invention is further described below in conjunction with the drawings and embodiments, but the present invention is not limited thereto.

[0011] Example:

[0012] Reference Figure 1 A method for producing aged water comprises the following steps: 1) Primary filtration: The source water 1 passes through the first filtering device 2 to filter out the granular sand and debris, and the filtered water enters the first water tank 3 for standby use; 2) Second filtration: The water in the first water tank 3 is filtered for the second time, and the second filtration is filtered through quartz sand, activated carbon, microporous filtration, and ultra-microporous filtration in sequence to obtain purified water, which is then input into the second water tank. In this example, the second filtration is sequentially filtered through the second filter device 4 filled with quartz sand, enters the third filter device 5 filled with activated carbon, the fourth filter device 6 provided with a microporous filter membrane, and the fifth filter device 7 provided with an ultra-microporous filter membrane, and enters the second water tank 8 for standby use; 3) First water boiling: The clean water in the second water tank is heated to above 99°C within 5 seconds by heat exchange to make cooked water. In this example, the clean water in the second water tank 8 is stored in the heat recovery water tank 10 for standby through the first channel of the primary double-channel plate heat exchanger 9. The standby clean water in the heat recovery water tank 10 is input from the heat recovery water tank 10 to the first channel of the energy-gathering double-channel plate heat exchanger 11. At the same time, the second channel of the energy-gathering double-channel plate heat exchanger 11 is connected to the steam generator 18, and the steam generated by the steam generator at a temperature of above 160°C is sent to the energy-gathering double-channel plate heat exchanger. The second channel of 11 exchanges heat energy with the clean water entering the first channel of the energy-gathering dual-channel plate heat exchanger 11. During the heat energy exchange between the clean water and the steam, the two substances cannot physically contact and mix with each other. After the steam in the second channel of the energy-gathering dual-channel plate heat exchanger 11 with a temperature of more than 160°C exchanges heat energy with the clean water in the first channel of the energy-gathering dual-channel plate heat exchanger 11, the clean water temperature will reach more than 99°C within five seconds. The high-temperature clean water in the first channel of the energy-gathering dual-channel plate heat exchanger 11 with a temperature of more than 99°C is directly input into the steam stew pot 12; 4) Second boiling: The cooked water after the first boiling is sent into the steam stew pot to maintain a water temperature of not less than 99°C, and maintained above 99°C under a standard atmospheric pressure, and stewed for 0.5-168 hours to make old cooked water. In this case, the stewing time is 7 hours, at which time the taste is the best; 5) Thermal cycle: The cooked water in the steam stew pot is sent to a cooling water circulation system with a cooling function to be cooled to obtain cooled cooked water. In this example, the cooked water in the steam stew pot 12 enters the first channel of the secondary double-channel plate heat exchanger 13 through the second channel of the primary double-channel plate heat exchanger 9. The second channel of the secondary double-channel plate heat exchanger 13 is connected to the cooling circulation system 19. The purified water in the second channel of the primary double-channel plate heat exchanger 9 and the cooked water in the first channel of the secondary double-channel plate heat exchanger 13 do not physically contact or mix with each other. The second channel of the secondary double-channel plate heat exchanger 13 and the cooling water from the cooling circulation system 19 cannot physically contact or mix with each other. 6) Re-filtration: The cooled aged water is filtered through nitrite and finely filtered. In this example, the cooled aged water coming out of the first channel of the secondary dual-channel plate heat exchanger 13 passes through the sixth filter device 14 capable of filtering nitrite and enters the seventh filter device 15 with fine filtration. 7) Sterilization: Step 6) The filtered aged water is sterilized by ultraviolet light and then sent to an ozone mixing device. In this example, the aged water filtered from the seventh filter device 15 passes through an ultraviolet sterilizer 16 and then enters an ozone mixing device 17 for mixing; 8) Finished product packaging: The water output from the ozone mixing device is a finished drinking aged water product that has undergone secondary steaming and is packaged and ready for drinking at any time.
