Description

Technical Field

[0001] This invention relates to the field of coffee extraction equipment technology, specifically to an industrial-grade intelligent flash coffee extraction device and its processing technology. Background Technology

[0002] ESPRESSO, or Italian espresso, is a coffee beverage obtained by high-pressure extraction of ground coffee powder. In industrial production, industrial coffee machines are often used for extraction. Traditional instant coffee solutions have a poor taste and are prone to having a "tire-like" flavor. There are not many existing coffee extraction devices, and most high-end equipment is semi-automatic. Although the output flavor is better, it lacks intelligence and consumes a lot of manpower. Moreover, since coffee drinking is mainly popular in Europe and America, high-end equipment is mostly imported, resulting in high costs. Domestic equipment also struggles to achieve a relatively stable extraction effect. Mechanical feeding during extraction can easily lead to powder accumulation, resulting in uneven extraction. Summary of the Invention

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

[0022] See Figure 1 - Figure 2 As shown, it includes a frame 1 and a brewer. A low-temperature grinder 2 is installed at the top of the frame 1, with a grinding temperature of 36℃ to ensure the quality of the coffee powder. Below it is a powder receiving box 3, and below the powder receiving box 3 is a powder feeding mechanism for feeding coffee powder into the brewer. The brewer has a powder distribution mechanism and a grounds removal mechanism on both sides. The frame 1 contains a boiler 42 for providing hot water to the brewer. A TDS detector 21 is installed on the water inlet pipe at the front end of the boiler 42, and an online concentration monitor 34 is installed on the liquid outlet pipe of the brewer. The boiler 42 is equipped with a dual-position temperature sensor 31 and a safety valve 32. The boiler temperature is monitored by the sensor, and with the help of PID control, a constant temperature water output is achieved. The front end of the TDS detector 21 is connected to the main water valve 19 and the filter 20, and the rear end is connected to the pressure sensor 24 and the flow meter 25. Then, it is connected to the water pump 26 for sending water backward. The rear end of the outlet of the water pump 26 is connected to two paths through a three-way valve. One path is connected to the hot water solenoid valve 28 after passing through the boiler 42, and the other path is connected to the cold water solenoid valve 27. Then, the two paths are connected to the pressure sensor 29 through the three-way valve. The rear end of the pressure sensor 29 is connected to the inlet of the brewer through the two-position two-way valve 37. The outlet of the brewer is connected to the concentration online monitor 34 through the two-position two-way valve 39. The rear end of the three-position three-way valve 35 is connected to the coffee storage box 41. The end of the two-position two-way valve 37 facing the pressure sensor 29 is also connected to the outlet of the brewer through the two-position two-way valve 38. The inlet of the brewer and the concentration online monitor 34 are connected by the two-position two-way valve 40. A temperature sensor 22 and a check valve 23 are also provided between the TDS detector 21 and the pressure sensor 24. A check valve 30 is also provided on the pipeline at the rear end of the pressure sensor 29. The pipeline between the pressure sensor 29 and the check valve 30 is also connected to the wastewater pipe through a control valve 33. The wastewater outlet of the boiler 42 is connected to the wastewater pipe. The pipeline between the online concentration monitor 34 and the coffee storage box 41 is connected to the wastewater pipe through a three-position three-way valve 35. A three-position three-way valve 36 is connected to the rear end of the coffee storage box 41. One end of the three-position three-way valve 36 is used to discharge coffee liquid, and the other end is connected to the wastewater pipe.

[0023] Filter 20 filters the incoming water and works with TDS detector 21 to monitor water quality, ensuring the incoming water is cooled. Check valve 1 23 and check valve 2 30 restrict the water flow direction at the equipment inlet and brewer inlet to prevent backflow. The water pump 26 has two parallel outlets, controlled by cold water solenoid valve 27 and hot water solenoid valve 28 respectively. Cold water or hot water from boiler 42 can be supplied as needed. Control valve 33 can directly discharge the outlet water for easy cleaning. At the brewer, two-position two-way valve 1 37 and two-position two-way valve 2 38 allow water to enter from above or below the brewer, respectively. Correspondingly, two-position two-way valve 39 and two-position two-way valve 40 control the water outlet. For example, in extraction, two-position two-way valve 1 37... When the water inlet is opened, the two-position two-way valve 2 (38) closes, and the extracted coffee liquid is discharged through the open two-position two-way valve 3 (39). The two-position two-way valve 4 (40) remains closed. Conversely, when the two-position two-way valves 1 (37) and 3 (39) are closed, and the two-position two-way valves 2 (38) and 4 (40) are opened, water enters from the top of the brewer and exits from the bottom for cleaning. Correspondingly, at this time, the three-position three-way valve 1 (35) switches to face the wastewater pipe, and the wastewater is discharged directly. When the coffee reservoir 41 needs to be cleaned, the three-position three-way valve 1 (35) switches to face the coffee reservoir 41, and the three-position three-way valve 2 (36) switches to face the wastewater pipe. The water flows through the coffee reservoir 41 and then exits. This realizes the valve group control pipeline switching for coffee extraction or cleaning of various components.

[0024] See Figure 1 - Figure 8 As shown, the coffee powder receiving box 3 is installed via a side-mounted weighing sensor 4 to monitor its weight and determine whether the coffee powder weight is sufficient. The top of the receiving box 3 has a sleeve structure for the coffee powder to enter from the low-temperature grinder 2, allowing the coffee powder to pass through without affecting the weighing due to slight movements of the receiving box 3. The powder feeding mechanism includes a powder trough cylinder 6 installed obliquely within the frame 1. An inclined lower powder trough 5 is connected above the drive slider of the powder trough cylinder 6. The lower powder trough 5 is located below the outlet of the receiving box 3. A powder mesh 7 is provided at the downward-facing opening of the lower powder trough 5. When the powder trough cylinder 6 extends, it drives the lower powder trough 5 to extend and align with the lower brewer 9. Retraction does not affect the closing of the brewer. The powder mesh 7 evenly distributes the coffee powder as it falls, preventing accumulation. Figure 8 As can be seen, a rotating movable door is provided at the opening below the powder box 3, and an opening cylinder 302 is installed on the side. The front end of the opening cylinder 302 is connected to a door stop 303. When the cylinder retracts, the door stop 303 abuts against the movable door to close it. When the cylinder extends, it can drive the door stop 303 away, and the coffee powder can use gravity to push open the movable door and then fall down. The brewing device consists of an upper brewer 8 and a lower brewer 9, employing countercurrent permeation extraction with a capacity of 2500ml and a 390,000-pore filter to prevent channeling effects. A support 10 is located within the frame 1, with the upper brewer 8 installed within it. The lower brewer 9 is slidably installed vertically, and a drive base 44 is located below it. A drive rod 45 for raising and lowering the lower brewer 9 is located at the bottom of the lower brewer 9. An extraction motor 43 is located within the frame 1, connected to the drive base 44 and then transmitted to the drive rod 45. A gear transmission mechanism is located within the drive base 44, and the drive rod 45 is a lead screw connected to the lower brewer 9 via a thread. The rotation of the lead screw drives the lower brewer 9 to rise and fall. This technology is existing technology and therefore is not shown separately in the accompanying drawings and will not be described further here. The powder distribution mechanism includes a horizontal drive component 11 connected to the top side of the support 10. The horizontal drive component 11 is horizontally positioned, and a vertically positioned longitudinal drive component 12 is connected to its drive slider. A mounting bracket is connected to the slider of the longitudinal drive component 12, and the mounting bracket is equipped with a powder distribution head 14 and a rotary motor 13 that drives the powder distribution head 14 to rotate. The powder distribution head 14 is positioned downwards. The horizontal drive component 11 is a cylinder, the longitudinal drive component 12 is an electric cylinder, and the powder distribution head 14 is a three-bladed propeller. The two components move the powder distribution head 14 horizontally and vertically, respectively, so that it can enter or leave the chamber in the lower brewer 9. When it enters the chamber, the rotary motor 13 is activated to drive the powder distribution head 14 to rotate, agitating the coffee powder to make its density more uniform, its height more consistent, and its surface more flat. This ensures that the water flow is consistent throughout the extraction process, guaranteeing product quality. Both the rotary motor 13 and the extraction motor 43 are servo motors to ensure control precision. The coffee grounds removal mechanism includes a coffee grounds removal cylinder 15 horizontally installed in the frame 1. A coffee grounds pusher head 16 is provided on its slider. When the lower brewer 9 is lowered, the top surface of the lower brewer 9 is flush with the bottom surface of the coffee grounds pusher head 16. A coffee grounds cart 17 is provided on the side of the brewer away from the coffee grounds removal cylinder 15. The coffee grounds removal cylinder 15 drives the coffee grounds pusher head 16 to push the coffee grounds directly out of the lower brewer 9 and fall into the coffee grounds cart 17. The coffee grounds cart 17 can be periodically removed and cleaned.

[0025] like Figure 1 - Figure 3 As shown, the frame 1 contains an electrical control cabinet 18. All the moving parts mentioned above are controlled by this electrical control cabinet 18. The electrical control cabinet 18 contains a PLC, which controls the operation of the equipment through a unified PLC program. The CPU of the PLC is a Siemens S7-1200 6ES7 215-1AG40-0XB0, which serves as the main control core of the equipment to control its operation in accordance with the coffee extraction process. The boiler PLC program and its programming are existing technologies, so they will not be described in detail here.

[0026] A processing technology for an industrial-grade smart coffee flash brewing device: S1. The low-temperature grinder 2 grinds coffee beans and feeds them into the powder receiving box 3. The powder receiving box 3 weighs the beans in real time. The powder trough cylinder 6 drives the lower powder trough 5 to extend and align with the lower brewer 9. When the powder receiving box 3 is full, the cylinder 302 is opened to drive the door stop 303 to leave and release the coffee powder. The coffee powder automatically falls into the lower brewer 9. After completion, the door stop 303 retracts to close the discharge and the powder trough cylinder 6 retracts the lower powder trough 5. S2. The coffee powder nozzle 14 is inserted into the lower brewer 9 to stir the coffee powder evenly and uniformly, and then it is removed from the lower brewer 9. S3, the extraction motor 43 starts, driving the lower brewer 9 to rise and flatten the coffee powder; S4. Water enters boiler 42 for heating, TDS detector 21 monitors water quality in real time, pressure sensor 1 24 and pressure sensor 29 monitor hot and cold water pressure respectively, and hot water is introduced into brewer to start extraction. S5. After the extracted coffee liquid is tested for concentration by the online concentration monitor 34, it is discharged into the coffee liquid storage box 41 for temporary storage, and then the finished product is discharged.

[0027] The installation, connection, or setting methods of the components not detailed above are all common mechanical methods, and the specific structure, model, and coefficient indicators of all their components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented, so they will not be elaborated further.

[0028] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of the invention and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the invention should be included within the protection scope of the invention.
