Description

Technical Field

[0001] This invention relates to the field of coffee processing technology, and in particular to a low-temperature coffee concentration system. Background Technology

[0002] Coffee, with its aromatic and delicious flavor, is an indispensable beverage in modern life. Many substances in coffee are water-soluble, such as fruit acids, caffeine, and oils. Coffee extraction is the process of extracting these water-soluble substances from coffee. According to years of research by coffee professionals, it is generally believed that only 30% of the substances in coffee are soluble, while 70% are insoluble carbohydrates. The coffee processing involves filtering the steeped coffee grounds, collecting the coffee liquid for concentration and drying. Low-temperature concentration (LTC) is a common method, where the boiling point of the coffee liquid is lowered under vacuum, allowing it to boil and evaporate at around 30 degrees Celsius. This method offers advantages such as fast concentration, low energy consumption, and preservation of the coffee's basic components. However, during LTC, the evaporated water is drained, leaving behind some aromatic coffee substances. Directly draining this water would be wasteful. Summary of the Invention

[0003] The purpose of this invention is to provide a low-temperature coffee condensation system that solves the problem of residual coffee aromatic substances in the water produced by low-temperature condensation, which is wasted, by pumping the water in the storage tank back into the hot water tank for continued heating and using it as hot water for brewing coffee.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0005] A low-temperature coffee condensation system includes a brewing assembly, a filtering assembly, and a low-temperature condensation assembly. The brewing assembly is connected to the filtering assembly, and the filtering assembly is connected to the low-temperature condensation assembly. The low-temperature condensation assembly includes an condensation tank, a vacuum pump, a vent pipe, a gas-liquid separator, a condenser, and a water storage tank. The vacuum pump and the vent pipe are connected to the condensation tank. The gas-liquid separator is located on the vent pipe. The water storage tank is connected to the end of the vent pipe away from the condensation tank. The condenser is located at the end of the vent pipe near the water storage tank.

[0006] It also includes a water heating assembly, which includes a hot water tank, a water pump, a first inlet pipe, a first valve body, a second inlet pipe, a second valve body, a first outlet pipe, a third valve body, a second outlet pipe, and a fourth valve body. The water pump is located outside the hot water tank. The first and second inlet pipes are connected to the inlet of the water pump. The first valve body is located on the first inlet pipe, and the end of the first inlet pipe away from the water pump is connected to the bottom of the hot water tank. The second valve body is located on the second inlet pipe, and the end of the second inlet pipe away from the water pump is connected to the bottom of the water storage tank. The first and second outlet pipes are connected to the outlet of the water pump. The third valve body is located on the first outlet pipe, and the end of the first outlet pipe away from the water pump is connected to the upper end of the hot water tank. The fourth valve body is located on the second outlet pipe, and the end of the second outlet pipe away from the water pump is connected to the brewing assembly.

[0007] A further feature of the present invention is that the hot water tank is provided with a water inlet pipe.

[0008] A further feature of the present invention is that it also includes a heating assembly, which includes a steam generator and several pipes, one end of which is connected to the steam generator, and the other end of which is connected to the hot water tank, the brewing assembly, the filtering assembly, the concentration tank and the storage tank respectively.

[0009] A further configuration of the present invention is as follows: the brewing assembly includes a brewing tank, a stirring mechanism, and a slag removal mechanism; the end of the second water outlet pipe away from the water pump is connected to the brewing tank; the pipe is connected to the brewing pipe; the stirring mechanism is used in conjunction with the brewing tank; the slag removal mechanism is located at the lower end of the brewing tank; an air inlet pipe is connected to the brewing tank; the end of the air inlet pipe away from the brewing tank is connected to the air outlet of the vacuum pump; a fifth valve body is provided on the air inlet pipe; an exhaust pipe is connected to the air outlet of the vacuum pump; a sixth valve body is provided on the exhaust pipe; a water storage tank is provided at the end of the exhaust pipe away from the vacuum pump; and the exhaust pipe is inserted into the water storage tank.

[0010] A further configuration of the present invention is that the first valve body, the second valve body, the third valve body, the fourth valve body, the fifth valve body, and the sixth valve body are all solenoid valves.

[0011] A further configuration of the present invention is as follows: the filtration assembly includes a bag filter, a tubular centrifuge, a first storage tank and a second storage tank, the first storage tank being disposed between the bag filter and the tubular centrifuge, the second storage tank being connected to the tubular centrifuge, and the pipes being connected to the first storage tank and the second storage tank respectively.

[0012] In summary, the present invention has the following beneficial effects:

[0013] Firstly, this invention collects the water produced after low-temperature concentration and pumps it into a hot water tank. The water is then heated and introduced into the brewing unit to brew coffee, thus remixing the aromatic substances of coffee with the coffee powder. This effectively recovers resources and saves water.

[0014] Secondly, the water pump in this invention can serve two purposes under the action of the first valve body, the second valve body, the third valve body and the fourth valve body. First, it can pump water from the storage tank into the hot water tank and then pump water from the hot water tank into the brewing component. Second, it can pump hot water from the bottom of the hot water tank and pump it into the top of the hot water tank to stir the water in the hot water tank and heat it more evenly.

[0015] Thirdly, the steam generated by the steam generator in this invention is transported to various components through pipelines for heating the hot water tank, and for heat preservation of the brewing tank, the first storage tank, the second storage tank, the concentration tank and the water storage tank, thus serving multiple purposes.

[0016] Fourth, in addition to evacuating the concentration tank, the vacuum pump in this invention can also introduce some of the extracted air into the brewing tank during the filtration and drainage process, thereby pressurizing the brewing tank, ensuring thorough filtration, and making rational use of resources.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] In the description of this invention, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0024] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] Example: A low-temperature coffee concentration system, such as Figures 1 to 3 As shown, it includes a brewing component 1, a filtering component 2, a boiling component 4, a heating component 5, and a low-temperature concentration component 3. The brewing component 1 is connected to the filtering component 2, and the filtering component 2 is connected to the low-temperature concentration component 3.

[0026] The low-temperature condenser assembly 3 includes a condenser tank 31, a vacuum pump 32, a vent pipe 33, a gas-liquid separator 34, a condenser 35, and a water storage tank 36. The vacuum pump 32 and the vent pipe 33 are connected to the condenser tank 31. The gas-liquid separator 34 is located on the vent pipe 33. The water storage tank 36 is connected to the end of the vent pipe 33 away from the condenser tank 31. The condenser 35 is located at the end of the vent pipe 33 near the water storage tank 36. The low-temperature condenser assembly 3 uses the vacuum pump 32 to extract the gas from the condenser tank 31, creating a vacuum state in the condenser tank 31. This lowers the boiling point of the coffee liquid, causing it to boil and evaporate. The steam is discharged through the vent pipe 33. When the steam passes through the gas-liquid separator 34, the aromatic coffee substances contained in the steam are collected and returned to the condenser tank 31. The steam continues to move forward, and when it passes through the condenser 35, the steam condenses into water. The water is then discharged into the water storage tank 36 for later use.

[0027] The water heating assembly 4 includes a hot water tank 41, a water pump 42, a first inlet pipe 43, a first valve body 44, a second inlet pipe 45, a second valve body 46, a first outlet pipe 47, a third valve body 48, a second outlet pipe 49, and a fourth valve body 410. The water pump 42 is located outside the hot water tank 41. The first inlet pipe 43 and the second inlet pipe 45 are connected to the inlet of the water pump 42. The first valve body 44 is located on the first inlet pipe 43. The end of the first inlet pipe 43 away from the water pump 42 is connected to the bottom of the hot water tank 41. The second valve body 46 is installed on the second water inlet pipe 45. The end of the second water inlet pipe 45 away from the water pump 42 is connected to the bottom of the water storage tank 36. The first water outlet pipe 47 and the second water outlet pipe 49 are connected to the water outlet of the water pump 42. The third valve body 48 is installed on the first water outlet pipe 47. The end of the first water outlet pipe 47 away from the water pump 42 is connected to the upper end of the hot water tank 41. The fourth valve body 410 is installed on the second water outlet pipe 49. The end of the second water outlet pipe 49 away from the water pump 42 is connected to the brewing component 1. The hot water tank 41 is provided with a water filling pipe 411.

[0028] When in use, the water heating component 4 heats water through the hot water tank 41. The water pump 42 draws water from the storage tank 36 into the hot water tank 41, heats it, and then draws it into the brewing component 1 to brew coffee. This effectively reuses residual coffee aroma compounds in the water and saves water. Of course, some water will be lost, which is replenished through the water inlet pipe 411. The water pump 42 can also draw hot water from the bottom of the hot water tank 41 and draw it in from the open end of the hot water tank 41 to stir the hot water, which helps to ensure even heating.

[0029] The heating component 5 includes a steam generator 51 and several pipes 52. One end of each pipe 52 is connected to the steam generator 51, and the other end is connected to the hot water tank 41, the brewing component 1, the filter component 2, the concentration tank 31, and the water storage tank 36, respectively. The steam generated by the steam generator 51 is distributed to each component through the pipes 52, and can be used to heat the hot water tank 41, and to keep the brewing tank 11, the first storage tank 23, the second storage tank 24, the concentration tank 31, and the water storage tank 36 warm, which is simple and convenient. Keeping the brewing tank 11 warm ensures the brewing effect. Keeping the first storage tank 23, the second storage tank 24, and the concentration tank 31 warm ensures the effect of low-temperature concentration. Keeping the water storage tank 36 warm allows for the continued heating and use of the water produced by low-temperature concentration.

[0030] The brewing assembly 1 includes a brewing tank 11, a stirring mechanism 12, and a slag removal mechanism 13. The end of the second water outlet pipe 49 away from the water pump 42 is connected to the brewing tank 11. The pipe 52 is connected to the brewing pipe. The stirring mechanism 12 works in conjunction with the brewing tank 11. The slag removal mechanism 13 is located at the lower end of the brewing tank 11. An air inlet pipe 14 is connected to the brewing tank 11. The end of the air inlet pipe 14 away from the brewing tank 11 is connected to the air outlet of the vacuum pump 32. A fifth valve body 15 is provided on the air inlet pipe 14. An exhaust pipe 16 is connected to the air outlet of the vacuum pump 32. A sixth valve body 17 is provided on the exhaust pipe 16. A water storage tank 6 is provided at the end of the exhaust pipe 16 away from the vacuum pump 32. The exhaust pipe 16 is inserted into the water storage tank 6.

[0031] The brewing tank 11, stirring mechanism 12, and slag discharge mechanism 13 are all existing technologies and will not be described in detail. After brewing, the brewing tank 11 needs to be filtered and drained. During this process, the air sucked in by the vacuum pump 32 is introduced into the brewing tank 11 to facilitate filtration. When it is not necessary to pressurize the brewing tank 11, the air sucked in by the vacuum pump 32 can be introduced into the water storage tank 6 for liquid sealing, and the small amount of steam carried in the air will also dissolve into the water.

[0032] It should be noted that the first valve body 44, the second valve body 46, the third valve body 48, the fourth valve body 410, the fifth valve body 15, and the sixth valve body 17 are all solenoid valves. This facilitates intelligent manufacturing and is simple and convenient.

[0033] The filter assembly 2 includes a bag filter 21, a tubular centrifuge 22, a first storage tank 23, and a second storage tank 24. The first storage tank 23 is located between the bag filter 21 and the tubular centrifuge 22, and the second storage tank 24 is connected to the tubular centrifuge 22. Pipes 52 connect the first storage tank 23 and the second storage tank 24 respectively. The bag filter 21 and the tubular centrifuge 22 are existing technologies and will not be described in detail. Steam can be introduced into the first storage tank 23 and the second storage tank 24 to keep the filtered coffee liquid warm, facilitating subsequent low-temperature concentration.

[0034] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
