Description

Technical Field

[0001] This invention relates to the field of beverage preparation equipment technology, and in particular to a beverage preparation equipment and a multi-weighing control method for beverage preparation. Background Technology

[0002] As people's living standards continue to improve, their demand for making beverages according to their own tastes is increasing, especially for specialty beverages such as coffee and tea. Even slight deviations in precision during the preparation process can lead to poor taste in the brewed beverage, making it difficult for users to have a better beverage preparation experience.

[0003] Traditional beverage machines, coffee machines, grinders, and roasters rely on single-point output scales or timers, primarily using preset time controls, flow meters, or pressure sensors to manage the brewing process. They cannot simultaneously track input, output, and absorption / retention rates. Measuring only the output yield fails to identify inefficient steps in the beverage preparation process, leading to discrepancies between the final product and the expected output. Furthermore, the lack of real-time proportional tracking, real-time feedback, and adaptive control prevents dynamic adjustments to preparation parameters, resulting in unstable extraction results. For example, traditional systems may stop brewing solely based on timers or estimated flow rates, ignoring dynamic factors such as the moisture retention of the coffee puck. Additionally, the user interfaces of such systems are typically fixed, offering limited space for immediate adjustments or personalized operation. In coffee and tea preparation, the inability to calculate losses or absorption in real time hinders quality balance and adaptive control, significantly limiting the accuracy of output during beverage preparation and thus impeding closed-loop brewing.

[0094] See Figure 2 In the beverage preparation equipment of this embodiment 1, the body 100 includes a main body 110, a base 120, a beverage preparation system 130, a serving platform 140, a control system 150 (e.g., a controller), and a display screen 160.

[0095] In the beverage preparation apparatus of this embodiment 1, the main body 110 is integrally formed with or detachably connected to the base 120. At least a portion of the beverage preparation system 130 and the control system 150 are disposed within the main body 110.

[0096] In the beverage preparation equipment of this embodiment 1, the beverage preparation system 130 is used to process the input raw materials and output the product, and the receiving container 200 is used to receive the product output by the beverage preparation system 130. The first weighing system 300 is used to measure the input weight of the raw materials in the beverage preparation system 130, measure the first mass change of the machine body 100 during the processing of raw materials, and obtain a first real-time reading. The second weighing system 400 is used to measure the second mass change of the product collected by the receiving container 200 during the processing of raw materials and obtain a second real-time reading, and measure the output weight of the product finally collected by the receiving container 200. The control system 150 is communicatively connected to the beverage preparation system 130, the first weighing system 300, and the second weighing system 400. The control system 150 controls the beverage preparation system 130 to process the raw materials according to the set values ​​of the input preparation parameters, and adjusts the preparation parameters in real time according to the input weight, the first real-time reading, and the second real-time reading.

[0097] In the beverage preparation equipment of this embodiment 1, the holding platform 140 is disposed on the base 120 and located below the beverage preparation system 130. The receiving container 200 is placed on the holding platform 140 and located below the beverage preparation system 130. The receiving container 200 is fixed to the holding platform 140 by magnetic attraction. The receiving container 200 can be a cup, pot, tray, measuring cup, etc. In another example of this embodiment 1, the receiving container 200 is a cup body 200.

[0098] In the beverage preparation equipment of this embodiment 1, the control system 150 is communicatively connected to the display screen 160. The display screen 160 is used to display in real time at least one of the set value and adjusted current value of the preparation parameters, the first real-time reading, and the second real-time reading.

[0099] The display screen 160 is an interactive touchscreen display.

Dynamic control components can also be set on the touchscreen display 160, allowing users to interact with them.

[0100] In the beverage preparation equipment of this embodiment 1, the beverage preparation system 130 includes an input module 131, a preparation module 132, and an output module 133. The input module 131 is used to receive input raw materials and output them to the preparation module 132. The preparation module 132 is used to process the raw materials and output the output through the output module 133. The first mass change measured by the first weighing system 300 is the mass of the raw materials output from the input module 131 to the preparation module 132. The second mass change measured by the second weighing system 400 is the actual output mass of the output collected by the receiving container 200.

[0101] In the beverage preparation equipment of this embodiment 1, the preparation parameters are one of the following, depending on the different beverage preparation systems 130: brewing parameters, grinding parameters, and roasting parameters. When the beverage preparation system 130 is a coffee machine or brewing machine, the preparation parameters are brewing parameters; when the beverage preparation system 130 is a coffee grinder, the preparation parameters are grinding parameters; and when the beverage preparation system 130 is a roasting machine, the preparation parameters are roasting parameters.

[0104] In another example of this embodiment 1, the second weighing system 400 is integrated into the holding platform 140.

[0105] See Figure 3 The beverage preparation equipment of Embodiment 1 of the present invention employs a multi-weighing control method executed by two weighing systems during beverage preparation, comprising the following steps:

[0106] S101: Open the beverage preparation equipment and input the set values ​​of the preparation parameters;

[0107] S102: Turn on the first weighing system, add raw materials to the beverage preparation system of the machine according to the set values ​​of the preparation parameters, and the first weighing system measures the input weight of the raw materials;

[0108] S103: Open the second weighing system and control the beverage preparation system to start processing raw materials;

[0109] S104: The first weighing system measures the first mass change of the machine body in real time and obtains the first real-time reading; the second weighing system measures the second mass change of the output collected by the receiving container in real time and obtains the second real-time reading.

[0110] S105: Adjust the preparation parameters in real time based on the input weighing, the first real-time reading, and the second real-time reading.

[0111] In the beverage preparation equipment of this embodiment 1, the first weighing system 300 is a Total Product Scale (TPS), used to measure the total weight of the machine body 100. Before beverage preparation, it records the input weighing TPS_Input of the raw materials added to the machine body 100. During the beverage preparation process, it records the system-level mass change of the machine body 100, i.e., the first mass change, and obtains the first real-time reading ΔM input in real time. The second weighing system is a Receiver Scale (RS), used to measure the final output collected by the receiving container 200. During the beverage preparation process, it records the mass change of the output of the receiving container 200, i.e., the second mass change, and obtains the second real-time reading ΔM output in real time. When the beverage preparation is completed, it records the output weighing RS_Output of the final output collected by the receiving container 200.

[0112] The parameters measured and recorded by the first weighing system 300 and the second weighing system 400 differ depending on the type of beverage preparation equipment.

[0113] For espresso machines or regular coffee machines, the first weighing system 300 is used to record the input weight of coffee powder and the change in the amount of water injected into the machine body 100, and the second weighing system 400 is used to record the change in the output of coffee liquid and the final output weight of the coffee liquid collected in the receiving container 200.

[0114] For the brewing machine, the first weighing system 300 is used to record the input weight of coffee powder raw materials and the change in the amount of water injected into the water tank, and the second weighing system 400 is used to record the change in the output of coffee liquid and the final output weight of the coffee liquid collected in the receiving container 200.

[0115] For the coffee grinder, the first weighing system 300 is used to record the input weight of the beans put into the machine body 100 and the mass change of the beans in the bean hopper. The second weighing system 400 is used to record the change of the amount of coffee powder collected by the receiving container 200 (powder cup) and the final output weight.

[0116] For the roaster, the first weighing system 300 is used to record the input weight of the green beans and the weight change of the beans due to moisture loss during the roasting process. The second weighing system 400 is used to record the output change of the roasted product and the final output weight of the roasted product collected in the receiving container 200.

[0117] The control system 150 precisely monitors the beverage preparation process using different calculation formulas, accurately maintains the real-time execution ratio of the beverage preparation process, automatically adjusts the preparation parameters to achieve closed-loop adjustment, and can automatically stop at the precise output or specific curve point.

[0118] For coffee brewing machines and espresso machines, the ratio formula is: brewing ratio = RS_Output / coffee powder dosage. The control system 150 monitors in real time whether the ratio of ΔM output / ΔM input is consistent with the brewing ratio. If they are inconsistent, other brewing parameters (pressure / flow rate / speed / heat / airflow, etc.) are adjusted in real time until they are consistent with the brewing ratio. This enables real-time verification of the brewing ratio and real-time adjustment of water flow and pressure applied to the coffee puck during the brewing process, and stops when the precise output target is reached.

[0119] For coffee grinders, the ratio formula is Grinding Ratio = RS_Output / TPS_Input. The control system monitors in real time whether the ratio of ΔM output / ΔM input is consistent with the grinding ratio. If they are inconsistent, other grinding parameters are adjusted in real time until they are consistent with the grinding ratio, thus tracking the trend of residual coffee powder.

[0120] For the roaster, the proportional formula is roasting shrinkage rate S% = (TPS_Input - RS_Output) / TPS_Input × 100. The control system monitors in real time whether the shrinkage rate of (ΔM input - ΔM output) / ΔM input × 100 is consistent with the roasting shrinkage rate. If they are inconsistent, other roasting parameters are adjusted in real time until they are consistent with the roasting shrinkage rate, so as to realize the real-time monitoring of coffee bean shrinkage rate and the accurate measurement of silverskin loss.

[0121] See Figures 4-6 The first embodiment of the present invention provides a coffee brewing machine, including a body 100 and a cup body 200. The body 100 includes a main body 110 and a base 120, the main body 110 being detachably connected to the base 120. The body 100 is provided with a beverage preparation system 130, a serving platform 140, a control system 150 (e.g., a controller), a display screen 160, a first weighing system 300, and a second weighing system 400.

The water tank 131 has an openable lid, the brewing chamber 132 is concealed within the main body 100, and the brewing module 133 extends from outside the main body 100 into the brewing chamber 132 and is fixed to the main body 100, detachably connected to the main body 110.

An external thread structure is provided on the outer surface of the upper opening of the connecting housing, and a corresponding internal thread structure is provided on the inner surface of the lower end of the body 110. Alternatively, an internal thread structure can be provided on the inner surface of the upper opening of the connecting housing, and a corresponding external thread structure can be provided on the outer surface of the lower end of the body 110. The connecting housing and the body 110 are connected by threads. A filter basket is fixed inside the connecting housing and is used to hold the raw materials for making beverages, such as coffee powder or tea cakes. When holding coffee powder, it is called a coffee basket, and when holding tea cakes, it is called a tea basket. A connecting shaft is fixed at the center of the filter basket and coaxially connected to the center of the sprayer assembly inside the brewing chamber 132. The brewing mode of the brewing module 133 can be selected according to the user's taste and preferences, including espresso, capsule coffee, drip coffee, tea bags, etc. When the user selects a brewing mode, such as espresso, the control system 150 will switch to the corresponding brewing mode, namely the espresso mode. Each brewing mode corresponds to different brewing parameters. These brewing parameters can be brewing schemes pre-stored in the control system 150, or brewing schemes that the user inputs on-site according to their preferred recipe.

[0123] A holding platform 140 is mounted on a base 120 and located below the beverage preparation system 130. A first weighing system 300 is integrated into the bottom of the base 120. A cup body 200 is placed on the holding platform 140 and located below the beverage preparation system 130. A second weighing system 400 is integrated into the bottom of the cup body 200. The first weighing system 300 and the second weighing system 400 can be electronic scales or combinations of weighing platforms and load sensors. Data is obtained by detecting changes in the vertical height of the weighing platform through the load sensor.

[0124] The display screen 160 is an interactive touch screen 160, through which users can select brewing modes, preset and adjust brewing parameters in real time, and save brewing recipes. For example... Figure 6 The diagram shows one layout of the user interface on the touch display screen 160 according to a first embodiment of the present invention. It should be noted that... Figure 6This is merely an example and not a limitation on user interface layouts. Any user interface layout that achieves the objectives of this invention is within the scope of protection of this invention. For example, Figure 6 The circular icon displaying the brewing ratio on the left can be placed next to the circular icon displaying the water temperature on the right, and the zeroing icon in the lower right can be placed next to the circular icon displaying the powder dosage in the lower left, and so on. Users can freely design the layout of all UI elements on the touchscreen display 160 according to their needs, preferences, and habits. The user interface on the touchscreen display 160 is a fully digital interface, where users can select brewing modes, view the current readings of brewing parameters, and adjust brewing parameters as needed. The touchscreen display 160 can also be equipped with dynamic control components, which users can interact with. For example, the professional mode in the espresso mode provides an interactive radar chart for setting the pressure-time curve, while the free mode supports touch-based step-by-step water pouring control.

[0125] The control system 150 is communicatively connected to the beverage preparation system 130, the display screen 160, the first weighing system 300, and the second weighing system 400. The first weighing system 300 measures the input weight of water and powder in the beverage preparation system 130. Before brewing, it verifies the water and powder dosage; during brewing, it monitors the actual amount of water added. The second weighing system 400 measures the output weight of the beverage in the cup 200. During brewing, it measures the accumulated weight of the beverage in the cup 200 and provides real-time feedback to ensure precise control of the final dispensing volume. The control system 150 adjusts the brewing parameters of the beverage preparation system 130 in real time based on the set values ​​of the input brewing parameters and the current readings of the input and output weighing. The display screen 160 displays the current readings of the input and output weighing parameters in real time. The brewing parameters include powder dosage, water volume, brewing ratio, brewing time, and the temperature, pressure, and flow rate of the water flowing through the powder.

[0126] The coffee brewing machine of the first embodiment 1 includes a drip brewer, a manual brewer, and a capsule brewer. Positioning the base 120 below the main body 110 allows for accurate measurement of the main body 110's weight, thereby precisely controlling the water injection volume and ensuring more stable extraction. During the brewing process, the remaining water level in the main body 110 can be viewed at any time via the touch display screen 160, allowing for adjustments to brewing parameters and optimization of the brewing effect as needed. The first weighing system 300 records the injected water volume, and the second weighing system 400 records the extracted coffee volume. Combining these two systems provides a comprehensive understanding of the extraction process, allowing for precise tracking and ensuring process control. The control system 150 automatically adjusts the brewing process based on the input weight data from the first weighing system 300 and the output weight data from the second weighing system 400, ensuring an ideal coffee powder to water ratio for a more stable taste and achieving intelligent optimized extraction.

[0127] See Figures 7-8 The second embodiment of the present invention provides an espresso machine, which differs from the coffee brewing machine of the first embodiment in only in shape and size. The main difference is that the machine body 100 is a one-piece molded structure, having a base 120, a support 101 extending obliquely upward from the base 120, and a housing 102 extending from the top of the support 101 to above the base 120. Part of the beverage preparation system 130 and the control system 150 are disposed in the housing 102. The holding platform 140 is disposed on the upper surface of the base 120. The first weighing system 300 is disposed in the base 120, and the second weighing system 400 is disposed in the holding platform 140. The brewing module 133 of the beverage preparation system 130 extends downward from the brewing chamber 132 outside the housing 102 and is detachably connected to the housing 102 and located above the holding platform 140.

[0128] like Figure 7 As shown, in one example of an espresso machine according to the second embodiment, the water tank 131 of the beverage preparation system 130 is a cylindrical structure protruding from the top of the housing 102, which facilitates the user to add water.

[0129] like Figure 8 As shown, in another example of the espresso machine in the second embodiment, the water tank 131 of the beverage preparation system 130 is an inclined structure located at the junction of the housing 102 and the support 101, which makes the espresso machine more aesthetically pleasing and increases the space utilization of the machine body 100.

[0130] See Figure 9 In the beverage preparation equipment of Embodiment 1 of the present invention, the specific operating steps of the coffee brewer and the espresso espresso machine using two weighing systems are as follows:

[0131] S401: Input the setting value of the brewing parameters;

[0132] S402: Open the first weighing system and add powder and water to the beverage preparation system according to the set values ​​of the brewing parameters;

[0133] S403: Turn on the second weighing system and start brewing the beverage;

[0134] S404: Real-time monitoring of the current readings of the input weighing of the first weighing system and the output weighing of the second weighing system;

[0135] S405: Adjusts brewing parameters in real time based on the set values ​​of brewing parameters, the current readings of input and output weighing.

[0136] The brewing parameters include the brewing ratio and powder dosage. In S402, adding powder and water to the beverage preparation system according to the brewing parameters includes calculating the amount of water to be added to the beverage preparation system 130 based on the input brewing ratio and powder dosage.

[0137] Step S405 also includes comparing the current readings of pressure and flow rate with the set values ​​of pressure and flow rate in real time. When the pressure or flow rate deviates from the set values ​​of pressure and flow rate, other brewing parameters (e.g., adjusting the powder dosage, water volume, brewing ratio, and brewing time) are adjusted in real time to ensure the consistency of beverage production under the current brewing mode.

[0138] Step S405 specifically includes monitoring whether the beverage currently being output from the cup 200 meets the expected brewing ratio by comparing the current readings of the input weighing and output weighing with their set values ​​in real time, and adjusting the brewing parameters in real time if they do not meet the expectations.

[0139] Step S405 also includes monitoring the water temperature in real time and adjusting it when the water temperature deviates from its set value in order to keep the water temperature within the set value range.

[0140] For ease of understanding, the following description uses the process of brewing coffee using a coffee maker and an espresso machine as an example to illustrate Embodiment 1 of the present invention.

[0141] Specifically, after the user inputs the brewing parameter settings, the main unit 110 is connected to the base 120, the cup 200 is placed on the holding platform 140 of the base 120, the first weighing system 300 is activated to record the total weight of the main unit 110 and the cup 200, and then the weight is zeroed. At this time, the display screen 160 shows that the input weight is 0.0 grams. Then, the main unit 110 is removed from the base 120, 20.0 grams of coffee powder is added to the coffee basket of the brewing module 133 according to the powder dosage setting, and the main unit 110 is put back into the base 120. The weight of the coffee powder is confirmed on the touch display screen 160, and then the weight is zeroed. In this way, the weight change of the coffee powder during the brewing process will be displayed on the touch display screen 160 in real time. The zeroing function allows users to more easily view the actual amount of coffee extracted. During extraction, the first weighing system 300 only calculates the amount of water flowing into the cup 200, ensuring more accurate measurement. Next, water is added to the water tank 131. Adding water stops when the first weighing system 300 detects that the added water weighs 100 grams. The second weighing system 400 is then activated to begin brewing. A variable-speed pump delivers water from the water tank 131 to the brewing chamber 132. The control system 150 is equipped with a pressure sensor that provides real-time feedback to ensure the pump operates according to a preset pressure curve. This pressure curve represents the change in water pressure with flow rate, indicating the pressure that should be applied to the water at different flow rates, ensuring that the water flow rate and pressure remain at the set values. During the brewing process, as the liquid is extracted, the second weighing system 400 continuously measures the weight of the brewed liquid, monitoring the increase in the weight of the beverage output in the cup 200. This weight change corresponds to the water output and can be recorded and monitored in real time. In this way, by tracking and measuring the remaining water in the water tank 131 through the first weighing system 300, the amount of coffee extracted in the cup 200 can be compared, which helps to analyze whether the extraction is sufficient. Finally, after a preset brewing time (e.g., 30 seconds), the control system 150 will stop the water flow, and the second weighing system 400 will display the final extraction amount (e.g., 60g of brewed coffee liquid) on the touch screen 160. The control system 150 will calculate the extraction efficiency and display it on the touch screen 160 to ensure that the brewing process meets the correct brewing parameter requirements. In this first embodiment, the main body 110 and the base 120 are separated. By integrating the weight, time, water flow rate, pressure, water temperature and brewing ratio settings into the control system 150 and through an interactive UI, users can finely adjust the brewing process to achieve a perfect extraction effect. The data from the first weighing system 300 and the second weighing system 400 are measured in real time, and with real-time pressure and flow rate feedback, the control system 150 can dynamically adjust the brewing parameters to accurately produce consistently high-quality coffee. The control system 150 can independently and accurately track the amount of water poured and the amount of coffee extracted, thereby controlling the brewing process more precisely and monitoring and optimizing the extraction effect in real time.This method avoids the uncertainty of relying on experience to judge the amount of water, making coffee extraction more stable, and is especially suitable for situations that pursue specific brewing ratios and extraction efficiency.

[0142] In addition to the user manually inputting or selecting the powder dosage and water volume, the control system 150 can also calculate the amount of water to be input into the beverage preparation system 130 based on the input brewing ratio and powder dosage before brewing. For example, if the user sets the coffee powder dosage to 20g and the brewing ratio to 1:2, the control system 150 will calculate the required water volume to be 40g. After brewing, the second weighing system will measure the output weight of the coffee in the cup 200 and compare it with the input water volume to ensure that the brewing ratio meets the set value.

[0143] Users can set the brewing time for the entire extraction process to control the contact time between water and coffee grounds. The control system 150 records the elapsed time to control the water flow rate based on the set brewing time. If the control system 150 is set to automatic control, the brewing time affects the water flow rate, and the control system 150 can adjust the water flow rate to ensure the correct amount of water is injected into the coffee puck within the set brewing time. The brewing time setting also affects the extraction efficiency and can be cross-referenced with the water pressure / flow rate settings. Based on the dynamically changing remaining time, the water pressure is adjusted in real time to control the water flow rate, thereby improving extraction efficiency and optimizing the extraction effect.

[0144] Users can set the water temperature (typically between 90-96°C for optimal extraction). The control system 150 then heats the water to the set temperature before extraction begins. Water temperature affects extraction speed and coffee grounds solubility, so the control system 150 adjusts brewing parameters (such as brewing time, water pressure, and flow rate) according to the set temperature. The touchscreen display 160 shows the current water temperature to ensure it reaches the user-set value before brewing begins. Water temperature affects extraction efficiency—too high or too low a temperature can lead to over-extraction or under-extraction. Maintaining the correct temperature ensures even extraction of the coffee grounds. During brewing, the control system 150 monitors the water temperature in real time to keep it within the set range.

[0145] Users can manually set the water pressure (typically 9 bar for espresso) and flow rate (e.g., 2 g / s) according to their brewing needs. The control system 150 controls the water flow rate and adjusts the water pressure passing through the coffee grounds based on the user's settings. During brewing, the control system 150 measures and displays the real-time water pressure and flow rate. The real-time pressure monitors the pressure exerted on the coffee grounds as water flows through them, ensuring the pressure remains at the correct level (e.g., 9 bar) throughout the extraction process. The real-time flow rate displays the amount of water flowing through the coffee grounds per second. By comparing the current pressure and flow rate readings with the set values ​​in real time, the control system 150 adjusts other brewing parameters (such as flow rate or brewing time) in real time when the pressure or flow rate deviates from the set values ​​to ensure consistency in the beverage produced under the current brewing mode and maintain optimal extraction. Based on the real-time monitored pressure and flow rate data, the extraction process can be optimized to ensure uniform contact between water and coffee grounds, guaranteeing stable extraction results. The settings for water pressure and flow rate are crucial for controlling the contact between water and coffee grounds, directly affecting the speed and uniformity of immersion and the final extraction volume. Real-time pressure and flow rate feedback ensures the brewing process remains within optimal ranges, providing consistent extraction results. Furthermore, in certain brewing modes, users can set pressure and flow rate values ​​in segments. For example, in the Pro espresso mode, the extraction process is divided into four stages: pre-wetting (gentle saturation), pre-infusion (gradually increasing water flow (pressure and temperature) to expand the coffee grounds and release their aroma), extraction (full pressure extraction), and pressure reduction (controlled, gradual decrease in pressure). Users can interactively set the pressure and brewing time for each stage via the user interface (e.g., an interactive radar chart) on the touchscreen display 160, allowing users to customize detailed pressure profiles. For instance, users can trace and plot pressure / flow rate curves on the touchscreen display 160 with their fingers, or click and drag points on the curve to dynamically adjust pressure and flow rate. The touchscreen display 160 displays the real-time adjusted plotted curves, including pressure and flow rate. In Freestyle Espresso mode, the manual overlay function allows for free adjustment of the pressure profile, enabling professional users to fine-tune the extraction process in real time. This provides unprecedented extraction control, allowing users to fine-tune for different coffee beans and brewing styles, achieving a highly personalized customization experience.

[0146] Users can select a brewing ratio (e.g., 1:1, 1:2, 1:2.5) to control the amount of water used per unit of coffee grounds. The control system 150 automatically adjusts the water volume according to the brewing ratio to match the dosage of coffee grounds. The control system 150 monitors the water in the second weighing system 400 and the final weight of the coffee produced to ensure the correct water volume is used and the desired ratio is achieved. The control system 150 compares the set brewing ratio with the actual water volume (tracked by the second weighing system 400) to ensure the output coffee quantity meets expectations. Taking into account the moisture retention of the coffee grounds (the water absorbed by the coffee grounds), the control system 150 ensures ideal concentration and flavor extraction by controlling the water-to-coffee ratio. If the second weighing system detects that the output weight does not match expectations, the control system 150 can adjust the brewing process or provide feedback to the user, prompting them to modify the settings.

[0147] The control system 150 of this invention tracks the input weight of water and the output weight of the beverage through the coordinated operation of a first weighing system and a second weighing system. This system-wide weighing calibration achieves real-time mass balance. Instead of relying on traditional flow meters or timers, the control system 150 uses real-time weight feedback to control the water pump to inject water into the water tank 131, automatically adjusting the water flow rate, pressure, and brewing time to optimize the extraction effect. This avoids inaccuracies caused by flow meter drift or timing errors, achieving precise volumetric dispensing and ensuring the stability and repeatability of each brewing. The control system 150 can monitor pressure and flow rate in real time, and with the weight tracking of the first and second weighing systems, it provides continuous feedback, enabling the control system 150 to adjust parameters in real time, optimize the extraction process, and ensure that the final coffee meets the user-set standards. Furthermore, the control system 150 can store complete brewing recipes (including brewing parameters such as coffee dosage, water volume, pressure profile, time, and temperature) and "learn" from each extraction using the real-time weight feedback mechanism of dual weighing, automatically adjusting future brewing parameters to optimize stability. Over time, the control system 150 adjusts the input water volume to compensate for the stable moisture retention in the coffee cake, thereby improving extraction consistency. Users can also save, load, edit, and share recipes through a cloud-based recipe library.

[0148] Specifically, during the brewing process, the control system 150 compares the current readings of the input weight measured in real time by the first weighing system 300 and the output weight measured in real time by the second weighing system with the set values ​​to calculate whether the beverage currently being dispensed from the cup 200 meets the expected brewing ratio. If it does not meet the expectations, the brewing parameters are adjusted in real time. During the brewing process, the control system 150 continuously monitors the output weight readings and automatically stops the water pump when the target dispensing volume is reached. That is, the control system 150 can cross-compare the current readings of the input and output weights in real time. For example, if the water weight measured by the first weighing system decreases by 40g, while the coffee weight measured by the second weighing system only increases by 36g, the control system 150 infers that 4g of water has been absorbed by the coffee grounds. This 4g is then used as feedback to optimize future brewing parameters to improve consistency.

[0149] In another example of the first embodiment of the present invention, the first weighing system 300 is integrated into the beverage preparation system 130.

[0150] In another example of the first embodiment of the present invention, the second weighing system 400 is integrated into the holding platform 140.

[0151] In another example of the first embodiment of the present invention, the cup body 200 is fixed to the holding platform 140 by magnetic attraction.

[0152] The beverage preparation equipment of the present invention described above can monitor water input and beverage output in real time, and uses continuous weight feedback to precisely control water delivery. It also provides an interactive adaptive user interface, allowing operators to dynamically adjust the pressure-time curve and brewing parameters. Furthermore, it supports multiple brewing modes (e.g., standard, professional, and free espresso modes, capsule brewing mode, and filter / tea infusion mode). In addition, different brewing modes can share the same weighing and sensor measurement principles, and can be switched within the same control system 150. When the user selects a different mode, the user interface on the touch display 160 will automatically adjust, displaying only the control options and preset parameters related to that mode, ensuring a simple and intuitive operating experience. A single device can be compatible with multiple brewing modes, including: espresso mode (standard, professional, and free modes), capsule mode, filter coffee mode (guided multi-stage pouring, free pouring), and tea infusion mode. The control system 150 uses a unified weight feedback control strategy and an interactive touch display 160 user interface, ensuring accurate brewing parameter management regardless of the selected brewing mode, thus providing a multi-functional brewing platform. Therefore, it can replace multiple independent devices, reduce costs, save space, and ensure high quality and consistency in different brewing modes.

[0153] Example 2

[0154] See Figure 10 In this embodiment 2, the beverage preparation equipment, based on the two-weighing-system structure disclosed in embodiment 1, adds a third weighing system 500. This third weighing system 500 is used to measure the third mass change of the beverage preparation system 130 during raw material processing and to obtain a third real-time reading. The control system 150 is communicatively connected to the third weighing system 500 and is used to adjust the preparation parameters in real time based on the input weighing, the first real-time reading, the second real-time reading, and the third real-time reading. The display screen 160 can display in real time the set value of the preparation parameters and the adjusted current value, as well as at least one of the first, second, and third real-time readings.

[0155] In the beverage preparation equipment of this embodiment 2, the beverage preparation system 130 also includes an input module 131, a preparation module 132, and an output module 133. The input module 131 is used to receive the input raw materials and output them to the preparation module 132. The preparation module 132 is used to process the raw materials and output the output through the output module 133. The first mass change measured by the first weighing system 300 is the mass of the raw materials output from the input module 131 to the preparation module 132. The third mass change measured by the third weighing system 500 is the theoretical output mass of the output from the preparation module 132 to the output module 133. The second mass change measured by the second weighing system 400 is the actual output mass of the output collected by the receiving container 200.

[0156] In the beverage preparation equipment of this embodiment 2, the first weighing system 300 is integrated into the bottom of the base 120, the second weighing system 400 is integrated into the bottom of the receiving container 200, and the third weighing system 500 is installed in the output module 133. The third weighing system 500 can be an electronic scale, directly set below the preparation module 132; or it can be a combination of a weighing platform and a load sensor, with the weighing platform set below the preparation module 132, and the load sensor directly set on the weighing platform or extending from the weighing platform and fixed inside the housing 102 in the form of a suspension structure, and data is obtained by detecting the longitudinal height change of the weighing platform through the load sensor.

[0157] See Figure 11 The beverage preparation equipment of Embodiment 2 of the present invention employs a multi-weighing control method executed by three weighing systems during beverage preparation, comprising the following steps:

[0158] S201: Open the beverage preparation equipment and input the set values ​​for the preparation parameters;

[0159] S202: Turn on the first weighing system, add raw materials to the beverage preparation system of the machine according to the set values ​​of the preparation parameters, and the first weighing system measures the input weight of the raw materials;

[0160] S203: Turn on the second and third weighing systems and control the beverage preparation system to start processing raw materials;

[0161] S204: The first weighing system measures the first mass change of the body in real time and obtains the first real-time reading; the second weighing system measures the second mass change of the output collected by the receiving container in real time and obtains the second real-time reading; the third weighing system measures the third mass change of the beverage preparation system and obtains the third real-time reading.

[0162] S205: Adjust the preparation parameters in real time based on the input weighing, the first real-time reading, the second real-time reading, and the third real-time reading.

[0163] In the beverage preparation equipment of this embodiment 2, the first weighing system 300 is a Total Product Scale (TPS), used to measure the total weight of the machine body 100. Before beverage preparation, it records the input weighing TPS_Input of the raw materials added to the machine body 100. During the beverage preparation process, it records the system-level mass change of the machine body 100, i.e., the first mass change, and obtains the first real-time reading ΔM input in real time. The second weighing system is a Receiver Scale (RS), used to measure the final output collected by the receiving container 200. During the beverage preparation process, it records the mass change of the output of the receiving container 200, i.e., the second mass change, and obtains the second real-time reading ΔM output in real time. When the beverage preparation is completed, it records the output weighing RS_Output of the final output collected by the receiving container 200. The third weighing system 500 is a Hanging Output Scale (HOS), which is set at the output position of the beverage preparation system 130. It is used to record the mass change of the product leaving the beverage preparation system 130, i.e., the third mass change, and to obtain the third real-time reading ΔM output in real time.

[0164] For different beverage preparation equipment, the parameters measured and recorded by the first weighing system 300, the second weighing system 400, and the third weighing system 500, as well as their specific functions, differ. The control system 150 precisely monitors the beverage preparation process through different calculation formulas, accurately maintains the real-time execution ratio of the beverage preparation process, distinguishes between system losses and downstream stagnation, automatically adjusts the preparation parameters to achieve closed-loop adjustment, and can automatically stop at precise output levels or specific curve points.

[0165] See Figure 12 In the first embodiment of Example 2 of the present invention, the beverage preparation equipment is a coffee brewing machine.

[0166] In the coffee brewing machine, the first weighing system 300 is used to record the input weight of coffee powder raw materials and the change in the amount of water injected into the water tank; the second weighing system 400 is used to record the mass change of the coffee liquid produced during the second and third stages of water injection and the final output weight of the coffee liquid collected in the receiving container 200; and the third weighing system 500 is used to record the mass change of the coffee liquid produced during each stage of water injection.

[0167] During the blooming stage of the coffee powder, the first real-time reading ΔM input decreases, while the second real-time reading ΔM output of the second weighing system 400 does not increase. The amount of coffee powder absorbed is confirmed by the first real-time reading ΔM input, which is the system loss L_sys = ΔM input - ΔM output. During the first stage of water pouring, the third weighing system 500 ΔM output increases, while the second real-time reading ΔM output of the second weighing system 400 lags behind, allowing the calculation of the coffee powder's blooming absorption as ΔM output. During the second and third stages of water pouring, the second real-time reading ΔM output continuously increases. Based on the set brewing ratio, the control system 150 adjusts the water volume or pouring time in real time. The brewing ratio formula is Brewing Ratio = RS_Output / Coffee Powder Dosage. The control system 150 monitors in real time whether the ratio of ΔM output / ΔM input is consistent with the brewing ratio. If they are inconsistent, other brewing parameters (pressure / flow rate / speed / heat / airflow, etc.) are adjusted in real time until they are consistent with the brewing ratio. Finally, water injection stops when the ΔM output / ΔM input reaches the set brewing ratio, continuing until brewing is complete. Ultimately, this achieves detection of the pre-brewing stage during the brewing process, precisely injecting water in stages and automatically stopping when the set brewing ratio is reached.

[0168] See Figure 13 In the second embodiment of Example 2 of the present invention, the beverage preparation equipment is an Italian coffee espresso machine.

[0169] In an espresso machine, the first weighing system 300 is used to record the input weight of coffee powder and the change in the amount of water injected into the machine body 100; the second weighing system 400 is used to record the change in the output of coffee liquid and the final output weight of the coffee liquid collected in the receiving container 200; and the third weighing system 500 is used to record the mass change of the small amount of coffee liquid flowing out during the pre-infusion stage and the mass change of the coffee liquid produced during the formal preparation stage.

[0170] Before coffee preparation, the first weighing system 300 detects changes in water volume and coffee powder dosage. During pre-infusion of the coffee powder, the second real-time reading ΔM output of the second weighing system 400 is still close to zero. The water consumption of the coffee powder is confirmed by the first real-time reading ΔM input, which is the system loss L_sys = ΔM input - ΔM output. During the pre-infusion stage, the third weighing system 500 begins to record a small outflow of coffee liquid ΔM output. At this time, the second real-time reading ΔM output of the second weighing system 400 is lagging, thus allowing the detection of the water absorbed by the coffee powder as ΔM output. During pressurized preparation of the coffee puck, both the second and third real-time readings ΔM output increase simultaneously. If the second real-time reading ΔM output is less than the expected value according to the brewing ratio formula, it is marked as downstream stagnation R_int = ΔM output - ΔM output. The brewing ratio formula is: Brewing Ratio = RS_Output / Coffee Powder Dosage. The control system 150 monitors in real time whether the ratio of ΔM Output / ΔM Input is consistent with the brewing ratio. If they are inconsistent, other brewing parameters (pressure / flow rate / speed / heat / airflow, etc.) are adjusted in real time until they are consistent with the brewing ratio. Finally, the control system 150 reduces the pump speed and ends the brewing process when RS_Output reaches the target output. Ultimately, this achieves real-time verification of the brewing ratio during the brewing process, real-time adjustment of water flow and pressure applied to the coffee puck, and stops when the precise output target is reached.

[0171] See Figure 14 In the third embodiment of Example 2 of the present invention, the beverage preparation equipment is a coffee grinder.

[0172] In the coffee grinder, the first weighing system 300 is used to record the input weight of the beans fed into the machine body 100 and the mass change of the beans in the bean hopper. The second weighing system 400 is used to record the change in the amount of coffee powder collected in the receiving container 200 (powder cup) and the final output weight. The third weighing system 500 is used to record the amount of coffee powder discharged from the chute.

[0173] Before grinding, the first weighing system 300 detects the input weight of coffee beans in the bean hopper and the mass change during the grinding process. While grinding the coffee beans, the second weighing system 400 and the third weighing system 500 jointly calculate the fine powder remaining in the grinding chamber, yielding the residue R_int = ΔM_output - ΔM_input. At this point, the control system 150 adjusts the motor speed according to the set grinding ratio, performing a purging operation until the slope of the curve showing the change in the third real-time reading ΔM_output flattens. The grinding ratio formula is Grinding Ratio = RS_Output / TPS_Input. The control system 150 monitors in real-time whether the ratio of ΔM_output / ΔM_input is consistent with the grinding ratio. If inconsistent, it adjusts other grinding parameters in real-time until they match the grinding ratio, thus achieving tracking of coffee powder residue, tracking of residual powder trends, and automatic cleaning of residual powder.

[0174] See Figure 15 In the fourth embodiment of Example 2 of the present invention, the beverage preparation equipment is a baking machine.

[0175] In the roaster, the first weighing system 300 is used to record the input weight of the green beans and the weight change of the beans due to moisture loss during the roasting process. The second weighing system 400 is used to record the output of the roasted products and the final output weight of the roasted products collected in the receiving container 200. It is also used to record the weight change of the roasted beans discharged from the drum.

[0176] Before roasting, the first weighing system 300 measures the input weight of the green beans, TPS_Input. During roasting, the first weighing system 300 detects a decrease in the first real-time reading ΔM input due to moisture loss. Based on the set roasting shrinkage rate, the control system 150 stops roasting and discharges the beans when the loss curve of the first real-time reading ΔM input matches the set roasting shrinkage rate. At this time, the third real-time reading ΔM output increases. The formula for the roasting shrinkage rate is: Roasting Shrinkage Rate S% = (TPS_Input - RS_Output) / TPS_Input × 100. The control system 150 monitors in real-time whether the shrinkage rate (ΔM input - ΔM output) / ΔM input × 100 is consistent with the roasting shrinkage rate. If they are inconsistent, other roasting parameters are adjusted in real-time until they match the roasting shrinkage rate. Silver husk retention is checked by comparing the third real-time reading ΔM output and the second real-time reading ΔM output. Thus, real-time monitoring of coffee bean shrinkage rate, accurate measurement of silver husk loss, and quality-based roasting curve analysis are achieved.

[0177] Example 3

[0178] See Figure 16Based on the structure of three weighing systems disclosed in Example 2, the beverage preparation equipment of this embodiment 3 adds at least one fourth weighing system 600, which is used to measure the fourth mass change of at least one waste or overflow during the processing of raw materials and obtain a fourth real-time reading; the control system 150 is communicatively connected to the fourth weighing system 600 and is used to locate the fault range in real time based on the first real-time reading, the second real-time reading, the third real-time reading and the fourth real-time reading.

[0179] The fourth weighing system 600 is installed in the waste / overflow collector 170 of the machine body 100. When the beverage preparation equipment is an espresso machine / coffee machine, the overflow collector 170 is installed at the serving platform 140, which can be an overflow tray or an auxiliary hopper. When the beverage preparation equipment is a roaster, a waste collector is installed at the beverage preparation system 130, which can be a silver-plated collection box, to distinguish between physical loss and evaporation loss of roasted beans.

[0180] See Figure 17 The beverage preparation equipment of Embodiment 3 of the present invention employs a multi-weighing control method executed by four weighing systems during beverage preparation, comprising the following steps:

[0181] S301: Open the beverage preparation equipment and input the set values ​​of the preparation parameters;

[0182] S302: Turn on the first weighing system, add raw materials to the beverage preparation system of the machine according to the set values ​​of the preparation parameters, and the first weighing system measures the input weight of the raw materials;

[0183] S303: Open the second weighing system, the third weighing system and at least one fourth weighing system, and control the beverage preparation system to start processing raw materials;

[0184] S304: The first weighing system measures the first mass change of the body in real time and obtains the first real-time reading; the second weighing system measures the second mass change of the output collected by the receiving container in real time and obtains the second real-time reading; the third weighing system measures the third mass change of the beverage preparation system and obtains the third real-time reading; and at least one fourth weighing system measures the fourth mass change of at least one waste or overflow and obtains the fourth real-time reading.

[0185] S305: Adjusts preparation parameters in real time based on input weighing, first real-time reading, second real-time reading and third real-time reading, and locates the fault range in real time by combining the fourth real-time reading.

[0186] The execution process of the multi-weighing control method in this embodiment 3 is basically the same as that in embodiment 2. The difference is that while executing the method in embodiment 2, the multi-weighing control method in this embodiment 3 can also monitor the waste / overflow in real time. Based on the amount of waste / overflow, the physical loss and evaporation loss in the preparation process can be distinguished. For example, in the roasting machine, the overall roasting loss is 10% of the input weighing TPS_Input. Based on the amount of silver skin collected in the silver skin collection box being 6% of the input weighing TPS_Input of the green beans, it can be known that the evaporation loss during the roasting process is 4% of the input weighing TPS_Input. Based on the ratio of the two, the location range of the fault location in the roasting machine can be narrowed.

[0187] The beverage preparation equipment and multi-weighing control method disclosed in this invention monitor the mass changes of the machine body and receiving container in real time through two weighing systems. This allows for real-time adjustment of preparation parameters during the beverage preparation process, precisely controlling the execution ratio of various beverage preparation scenarios. A third weighing system can simultaneously monitor the mass changes of the beverage preparation system, providing real-time and accurate feedback and closed-loop adjustment of preparation parameters. This enables the differentiation and monitoring of system losses and downstream residues during raw material processing, thereby maintaining the consistency of the prepared beverage quality. Furthermore, additional weighing systems can be used to measure and monitor waste and overflow generated in the beverage preparation equipment, distinguishing between physical losses and evaporation losses and narrowing the fault location range. Based on direct measurement of input and output weighing, the beverage preparation equipment can automatically stop at the expected output or a specific curve point, ensuring the stability, consistency, and repeatability of each brewing.

However, the present invention is not limited to the specific embodiments described above.
