Description

Drink dilution and temperature adjustment brewing mechanism

The present invention relates to a brewing mechanism, in particular to a beverage diluting and temperature-adjusting brewing mechanism for brewing American coffee using an Italian coffee machine.

In addition to providing various Italian coffee items, Italian coffee shops also add hot water to Italian espresso to make a lighter Americano-like coffee (hereinafter referred to as Americano). Because it is extracted by high pressure (8-10 bar), its taste is stronger than the pure Americano produced by the traditional Americano drip brewing machine, and the brewing time is faster. Therefore, it is a common practice to use an Italian coffee machine to brew Americano. When using an Italian coffee machine to brew Americano, the previous technology TW M342119U "Strong and Light Dual-purpose Temperature Control Brewing Mechanism" and CN 102217900B "Beverage Preparation Device" already have the function of diluting Italian espresso into Americano by adding water. Among them, TW The M342119U "strong and weak dual-purpose temperature-controlled brewing mechanism" mixes the hot water produced by the boiler and the cold water from the water source with a regulating valve to form hot water of a preset temperature, which is then added to the beverage cup and mixed with the espresso brewed by the espresso brewing device in the cup to form American coffee. This improves the problem that the temperature of the American coffee beverage is too high to be consumed immediately when the espresso is directly mixed with hot water, and that there is a risk of accidentally knocking over the coffee cup and scalding someone. However, its disadvantage is that the dilution water has a single temperature, which cannot meet the needs of customers who require various temperatures.

In addition, CN 102217900B "Drink Preparation Device" has a solenoid valve for hot water and cold water for dilution respectively. The automatic control system can control the opening and closing of the hot water solenoid valve and the cold water solenoid valve according to the preset temperature and CC number with the flow rate (CC number) detected by the flow meter, so as to achieve American coffee with different preset temperatures. However, there are still some shortcomings, including different seasons of the year, such as the outdoor temperature may reach above 40℃ in summer and the cold front in winter. In seasons with large daily temperature differences, the water temperature may be lower than 15°C. In seasons with large daily temperature differences, the water temperature may differ by more than 12°C between noon and evening. If the automatic control system is set to a fixed CC number of hot and cold water mixtures, the temperature difference of the water source will cause a significant temperature drop in the expected finished temperature of the American coffee, which cannot meet the needs of customers with higher requirements. The selection of multiple temperatures for coffee drinks and more accurate temperatures will be a goal that must be improved in the increasingly competitive coffee drink market.

The technical problem to be solved by the present invention is to provide a beverage dilution and temperature-adjusting brewing mechanism in view of the deficiencies of the prior art, which can provide a variety of beverage temperature options and more accurate temperatures, and can meet the needs of customers who need various temperatures and can meet the needs of customers with higher requirements.

[Example 1]

Please refer to Figures 1 and 2. The present invention provides a beverage dilution and temperature adjustment brewing mechanism. Italian coffee is a common brewing equipment. Figure 1 does not fully present the entire mechanism. It is only a partial schematic diagram indicating that the mechanism is a brewing mechanism of an Italian coffee machine. In addition, tea shops also use Italian coffee machines to extract tea soup, and the brewing process is similar to Italian coffee. Therefore, the present invention is not limited to brewing only American coffee.

The beverage dilution and temperature-adjusting brewing mechanism comprises a mother pot 1, a heater 2, a sub-pot 3, a brewing hot water pipe 4, a temperature-adjusting hot water pipe 5, a hot water solenoid valve 6, a first throttling device 7, a pump 8, a cold water pipe 9, a temperature-adjusting cold water pipe 10, a cold water solenoid valve 11, a second throttling device 12 and a brewing device 13.

The mother pot 1 is a hollow container, and the mother pot 1 can contain water. The mother pot 1 can be connected to a pipeline (not shown) to transport cold water to the mother pot 1 . The heater 2 is installed in the mother pot 1, and the heater 2 can be used to heat the water in the mother pot 1. The sub-pot 3 is arranged in the mother pot 1. The mother pot 1 and the sub-pot 3 form a sub-pot boiler. The high temperature of the hot water in the mother pot 1 can be transferred to the sub-pot 3 to heat the water in the sub-pot 3. . The mother pot 1 can also be equipped with a pressure switch 14, a safety valve 15, an exhaust valve 16 and a water level controller 17, etc., to increase the safety of use. The Italian coffee machine is a mature product, so only the key points are selected. Give a brief explanation.

The water temperature in the sub-pot 3 can be produced to a temperature suitable for brewing espresso through heat exchange with the main pot 1. The sub-pot 3 has a first outlet 31. The brewing hot water pipe 4 is connected to the first outlet 31. The temperature-adjusting hot water pipe 5 is connected to the brewing hot water pipe 4, so that the hot water in the sub-pot 3 can be sequentially transported to the brewing hot water pipe 4 and the temperature-adjusting hot water pipe 5 through the first outlet 31. The brewing device 13 is connected to the brewing hot water pipe 4, so that the hot water in the sub-pot 3 can be sequentially transported to the brewing hot water pipe 4 and the brewing device 13 through the first outlet 31. The brewing device 13 is equipped with a brewing solenoid valve 23 to control the output of hot water so as to perform the brewing process of espresso. A water return pipe 25 may also be provided between the brewing device 13 and the sub-pot 3.

The hot water solenoid valve 6 and the first throttling device 7 are installed on the temperature-adjusting hot water pipe 5. The first throttling device 7 can be a throttling valve or a throttling joint, etc. The first throttling device 7 can adjust the flow rate of the temperature-adjusting hot water so that the intensity of the hot water will not splash outside the beverage cup when it flows into the beverage cup.

The cold water pipe 9 is connected to the pump 8, and the pump 8 can be connected to a water source to input cold water, so that the cold water is transported to the cold water pipe 9 through the pump 8. A flow meter 18 is arranged on the cold water pipe 9, and the cold water outputted by the pump 8 can be measured by the flow meter 18. A one-way pressure relief valve 19 can also be arranged on the cold water pipe 9.

The sub-boiler 3 is connected to the cold water pipe 9 so that cold water can be delivered to the sub-boiler 3. The temperature-adjusting cold water pipe 10 is connected to the cold water pipe 9 so that cold water can be delivered to the temperature-adjusting cold water pipe 10 through the cold water pipe 9. The cold water solenoid valve 11 and the second throttling device 12 are installed on the temperature-adjusting cold water pipe 10. The second throttling device 12 can be a throttling valve or a throttling joint, etc. The second throttling device 12 can adjust the flow rate of the temperature-adjusting cold water so that the cold water will not splash outside the drink cup when it flows to the drink cup.

The temperature-controlled hot water pipe 5 has a second outlet end 51, and the temperature-controlled cold water pipe 10 has a third outlet end 101. The second outlet end 51 of the temperature-controlled hot water pipe 5 and the third outlet end 101 of the temperature-controlled cold water pipe 10 can be combined and connected to a temperature-controlled water outlet pipe 21 by means of a tee pipe 20 or the like. A temperature detector 22 is installed in the temperature-controlled water outlet pipe 21 to detect the temperature of the temperature-controlled water.

The one-way pressure relief valve 19 can keep the hot water pressure of the boiler within the preset pressure range during standby and heating, and prevent the hot water from backflowing and scalding the flow meter 18 and the pump 8. When the Italian coffee brewing process is executed, the pump 8 and the brewing solenoid valve 23 are started, and the hot water flow is measured by the flow meter 18. When the preset brewing coffee volume is reached, the automatic control system closes the pump 8 and the brewing solenoid valve 23 to complete the Italian coffee brewing process.

The espresso machine is designed to brew American coffee, using the preset temperature and total CC number of American coffee, the CC number of espresso brewing and the temperature of the coffee liquid, the temperature of cold water and the temperature of hot water flowing out of the boiler. The automatic control system calculates how many CC numbers of cold water and hot water to add, and finally the espresso and cold and hot water are mixed into the American coffee with the preset CC number and temperature. Since the present invention is used for both Italian coffee and American coffee, the operation buttons 30 and 40 can be provided with Italian coffee buttons and American coffee buttons (as shown in FIG. 3 ). There are 4 sets of operation buttons 30 and 40 for Italian coffee and American coffee respectively. For example, the automatic control system of button No. 1 sets the total volume of a cup of American coffee to 250 CC, the coffee liquid temperature to 50°C, and the Italian coffee liquid to brew 80 CC. The automatic control system sets the calculation formula for the amount of cold water and hot water to be added. The other 3 American coffee operation buttons are set with different operation procedures according to the customer's ordering requirements, such as different total CC numbers, concentrations and temperatures. The operation buttons 30 and 40 can also display the operation buttons on a touch screen or in other ways. The implementation method or number of the operation buttons 30 and 40 is not limited.

The American coffee brewing program embodiment is described with quantitative data. Assume that the American coffee No. 1 button is preset to brew 250CC of American coffee with a coffee liquid temperature of 50°C, and 80CC of espresso. Since espresso brewing is a fixed program, the espresso liquid temperature can be set to 82°C based on experience, and the temperature-adjusted hot water can be set to 96°C based on experience. If different espresso machines have different temperature values due to differences in the design of the mechanism, the actual operating experience temperature value is used as the calculation basis. The cold water is calculated based on the temperature detected by the temperature detector 22. In this embodiment, the cold water temperature is assumed to be 25°C.

Execution steps: Press the American coffee operation button 1, the automatic control system starts the pump 8 and the brewing solenoid valve 23 to start the Italian coffee brewing process, the flow meter 18 starts to measure, when the flow meter 18 measures that the output water volume reaches 80CC, the brewing solenoid valve 23 is closed, and the cold water solenoid valve 11 is opened at the same time, the flow meter 18 continues to measure, the pump 8 remains in the starting state, and the temperature detector 22 detects the cold water temperature. When the cold water flow reaches 10CC, the temperature detector 22 detects the cold water temperature The temperature is 25℃, which is the basis for the calculation of the automatic control system. The automatic control system calculates the number of CCs of cold water and hot water to be added. When the flow meter 18 measures that the total flow of cold water to be added this time reaches the predetermined CC number, the cold water solenoid valve 11 is closed, and the hot water solenoid valve 6 is opened at the same time. The pump 8 continues to be started. When the flow meter 18 measures that the total amount of water flowing through reaches 250CC, the automatic control system closes the hot water solenoid valve 6 and the pump 8, completing the American coffee brewing process of 250CC and 50℃.

[Example 2]

In this embodiment, the temperature-adjusting solenoid valve 11 for cold water and the solenoid valve 6 for hot water are opened and closed twice. The Americano 2 button is set to brew 300CC of Americano coffee at a liquid temperature of 55°C, and 100CC of espresso coffee. The espresso brewing is a fixed program. The temperature of the espresso liquid is based on the empirical value and can be set to 82°C. The temperature of the hot and cold water for temperature adjustment is calculated based on the temperature value detected by the temperature detector 22. Brewing process: Press button 2 (as shown in Figure 3), the automatic control system starts pump 8 and brewing solenoid valve 23 to start the espresso brewing process, and flow meter 18 starts measuring. When the flow meter 18 measures that the output water volume reaches 100CC, the brewing solenoid valve 23 is closed, and the cold water solenoid valve 11 is opened at the same time. The flow meter 18 continues to measure. Pump 8 remains in the start-up state, and temperature detector 22 detects the cold water temperature. When the cold water flow reaches 10CC, the cold water temperature detected by temperature detector 22 is 20℃. The automatic control system memorizes the cold water temperature, and 20℃ is the basis for the calculation of the automatic control system. At the same time, the cold water solenoid valve 11 is closed and the hot water solenoid valve 6 is opened. The flow meter 18 continues The pump 8 is kept in the start state, and the temperature detector 22 detects the hot water temperature. When the hot water flow reaches 10CC, the hot water temperature detected by the temperature detector 22 is 94℃. The automatic control system memorizes the hot water temperature, and 94℃ is the calculation basis of the automatic control system. The automatic control system calculates the number of CCs required for cold water and hot water. When the flow meter 18 measures that the total flow of hot water for this temperature adjustment reaches the predetermined CC number, the hot water solenoid valve 6 is closed, and the cold water solenoid valve 11 is opened at the same time. The pump 8 continues to keep the start state. When the flow meter 18 measures that the total amount of water flowing through reaches 300CC, the automatic control system closes the hot water solenoid valve 6 and the pump 8, completing the American coffee brewing process of 300CC and 55℃.

[Example 3]

Please refer to FIG. 4. In this embodiment, the cold water solenoid valve 11 is replaced by a cold water proportional valve 24, which is installed on the temperature-adjusting cold water pipe 10. The Americano 3 button is set to brew 300CC of Americano coffee at a coffee liquid temperature of 50°C, and 100CC of espresso coffee. The espresso brewing is a fixed program. The espresso liquid temperature can be set to 82°C based on the empirical value. The automatic control system calculates that 200CC of the mixed water after warm water and cold water are added, and the temperature is 34°C. Brewing process: Press button 3 (as shown in Figure 3), the automatic control system starts pump 8 and brewing solenoid valve 23 to start the espresso brewing process, and the flow meter 18 starts to measure. When the flow meter 18 measures that the output water volume reaches 100CC, the brewing solenoid valve 23 is closed, and the cold water proportional valve 24 and the hot water solenoid valve 6 are opened at the same time. The flow meter 18 continues to measure, and the pump 8 remains in the starting state. The temperature detector 22 detects the water temperature after the cold water and hot water are mixed. The temperature detector 22 detects the water temperature. The temperature of the hot and cold mixed water is not 34°C, and the automatic control system automatically adjusts the opening of the cold water proportional valve 24. When the temperature detector 22 detects that the temperature of the hot and cold mixed water is 34°C, the cold water proportional valve 24 maintains the same opening. The automatic control system randomly controls the cold water proportional valve 24 to keep the hot and cold mixed water at 34°C. When the flow meter 18 measures that the total flow rate reaches 300CC, the hot water solenoid valve 6, the cold water proportional valve 24 and the pump 8 are closed to complete the American coffee brewing process of 300CC and 50°C.
