For example, the extraction pressure is from 6 bar to 8 bar.

In some embodiments, after the tea powder is sent to the infusion unit 240, the water supply unit 230 provides 10-15 grams of pre-infusion water at 80°C-95°C to the infusion unit 240 to perform a pre-infusion process on the tea powder, and Obtain the first tea liquid. Here, the pre-infusion procedure is to infuse the tea powder with pre-infusion water for 5 seconds to 9.9 seconds. In addition, after the obtained primary tea liquid directly flows to the discharge port 900 through the third drain pipe 630 , the primary tea liquid can be sent to the container 300 placed at the discharge port 900 .

In some embodiments, after the tea liquid is initially sent to the container 300, the water supply unit 230 then provides 85g-240g of tea extraction water at a temperature of 80°C-95°C to the infusion unit 240, so as to perform the extraction process on the pre-infused tea powder , and obtain concentrated tea liquid and tea residue cake. Here, the extraction procedure is to extract the pre-infused tea powder at an extraction pressure of 6 bar to 8 bar for up to 2 minutes. In addition, after the obtained concentrated tea liquid flows to the discharge port 900 through the third drain pipe 630, the concentrated tea liquid can be sent to the container 300 placed at the discharge port 900, and the remaining tea powder forms a tea residue cake and The soaking unit 240 is discharged through the slag discharge port 249 . In addition, the time error between the step of "sending the first tea liquid to the container 300" and the step of "providing the tea extraction water from the water supply unit 230" is 0 seconds to 1 second. In other words, after the first tea liquid is discharged from the infusion unit 240 , the tea extraction water then enters the infusion unit 240 .

In some embodiments, the processing module 200 can simultaneously control the water supply unit 230 to provide tea extraction water to the infusion unit 240 and to provide the reconstituted water to the container 300 . In some embodiments, the processing module 200 may firstly control the water supply unit 230 to provide tea extraction water to the infusion unit 240, and during the extraction process, control the water supply unit 230 to supply the dispensing water to the outlet 900, so that the dispensing water is It is sent to the container 300 placed at the outlet 900 . Based on this, the time for preparing the tea can be reduced and the production of the tea can be accelerated.

In some embodiments, the container 300 is a paper cup, a plastic cup or other container that can hold liquid. For example, the container 300 can be a 700ml paper beverage cup, or a 500ml paper beverage cup. In some embodiments, the container 300 is placed under the discharge port 900 to receive liquids such as primary tea liquid, concentrated tea liquid, and preparation water for preparing tea.

The slag discharge unit 700 is connected to the infusion unit 240 and is used to remove the tea residue cake obtained after the extraction process from the infusion unit through the slag discharge port 249 of the infusion unit 240 . 240 excluded. For example, the slag discharge unit 700 is a pushing device and is disposed in the soaking unit 240 . When the extraction process is finished, the processing module 200 controls the slag discharge port 249 to open, and controls the slag discharge unit 700 to actuate to push the tea residue cake in the infusion unit 240 to the slag discharge port 249, so that the tea residue cake can flow from the slag discharge port. 249, and drop into the slag discharge box (not shown) below the soaking unit 240. In some embodiments, when the weight ratio of the tea powder and the total water is 1:15-1:30, the water content of the obtained tea residues is maintained at 50%-70%, so that a tea residue cake is formed and discharged into the Immersion unit 240. Based on this, it is possible to prevent the tea powder from swelling and sticking to the infusion unit 240, resulting in the inability to discharge the slag smoothly, and to avoid the failure caused by the blockage caused by the adhesion of the tea powder to the infusion unit 240 or the pipeline (such as the third drain pipe 630). , and to avoid residual tea powder affecting the flavor of subsequent tea drinks.

In some embodiments, the processing module 200 further includes a mixing unit 800 for sending at least one flavoring liquid to the container 300 to be mixed with the first tea liquid and the concentrated tea liquid into a tea drink. In addition, the dispensing unit 800 is connected to the discharge port 900 by the fourth drain pipe 640 . For example, at least one flavoring liquid, such as milk, plain syrup, fruit-flavored syrup (such as lemon-flavored syrup, etc.), can be placed in the blending unit to prepare tea, milk tea or fruit tea with different sweetness. In addition, different seasoning liquids in the mixing unit each have a corresponding fourth drain pipe 640, so as to avoid mixing of seasoning liquids of different flavors with each other. The flow direction of the seasoning liquid is shown by the solid arrow M. In some embodiments, after the first tea liquid, the concentrated tea liquid, the preparation water and the seasoning liquid are prepared into a tea drink, the sugar content of the obtained tea drink is 0.2 Brix-1.0 Brix.

In addition, in addition to preparing the first tea liquid and the concentrated tea liquid with the seasoning liquid and the preparation water, additives such as ice cubes and frozen pearls can be added to the container 300 externally, so as to be prepared into iced pure tea drinks, or supplemented tea drinks (such as bubble tea).

See Figure 3. In some embodiments, a tea extraction method includes grinding the tea raw material 400 to obtain tea powder (step S100 ), soaking the tea powder with pre-infusion water for 5 seconds to 9.9 seconds to obtain the first tea liquid (step S200 ), and extracting tea water in The steeped tea powder is extracted at 6 bar to 8 bar for up to 2 minutes to obtain concentrated tea liquid and tea residue cake (step S300 ), and the concentrated tea liquid and primary tea liquid are prepared to obtain tea drink (step S400 ).

See Figures 1 through 3. In some examples, after the operation panel 100 starts the tea extraction procedure, the tea extraction procedure performed by the processing module 200 includes the following steps:

First, the tea raw material 400 is provided. In other words, it refers to providing the tea raw material 400 stored in the tea storage unit 210 to the grinding unit 220 . Here, the processing module 200 takes 5 grams to 15 grams of the raw material 400 of the tea leaves stored in the tea storage unit 210 corresponding to the tea type according to the instruction generated by the tea type selected by the operator on the operation panel 100, and passes the first The blanking pipe 510 is sent to the grinding unit 220 .

Next, the processing module 200 controls the grinding unit 220 to grind the tea raw material 400 to obtain tea powder (ie, step S100 ). After the tea raw material 400 passes through the grinding disc of the grinding unit 220, it is uniformly crushed into tea powder with a particle size of less than 2 mm. In addition, when the tea powder is produced, it is sent to the infusion unit 240 through the second blanking pipe 520 . Here, the amount of the ground tea powder is 5 grams to 15 grams.

After the tea powder is sent to the infusion unit 240 , the processing module 200 controls the water supply unit 230 to provide pre-infusion water of 10g-15g at 80°C-95°C to the infusion unit 240 through the first drain pipe 610 , and controls the infusion unit 240 Perform a pre-soak procedure. After the pre-infusion process is started, the tea powder is infused with pre-infusion water for 5 seconds to 9.9 seconds to obtain the first tea liquid (ie, step S200). Here, the pre-infusion process simulates the traditional way of brewing tea, in which the tea powder is infiltrated with a small amount of pre-infusion water to facilitate the subsequent extraction process.

The tea powder of good black tea is sent to the infusion unit 240 . Next, the water supply unit 230 provides 15 grams of pre-infusion water at 92° C. to the infusion unit 240, and the processing module 200 controls the infusion unit 240 to infuse the tea powder of black tea with the pre-infusion water for 9.9 seconds to obtain the first tea liquid of black tea, The first tea liquid is sent to the cup container 300 . Next, the water supply unit 230 provides 145 grams of tea extraction water at 92° C. to the infusion unit 240, and the processing module 200 controls the infusion unit 240 to extract the tea powder of the infused black tea at 7 bar with the tea extraction water for 35 seconds, so as to obtain the black tea extract. Concentrated tea liquid and tea residue cake. And during the extraction period of at most 2 minutes, the water supply unit 230 provides 250 grams of blended water at 92° C. to the cup container 300 to be mixed with the first tea liquid of black tea. After the extraction, the concentrated tea liquid of the black tea will be sent to the cup container 300 to be mixed with the preparation water and the first tea liquid of the black tea to form a 410-gram black tea drink. Here, the total preparation time of the black tea drink is 65 seconds. The total water content of pre-infusion water and tea extraction water was 160 grams, the ratio of tea powder to total water content of black tea was 9:160 (ie, 1:17.8), and the water content of tea residue cake of black tea was 65%.

In another example, the consumer chooses to buy green tea. The salesperson selects green tea on the operation panel 100 of the tea extraction system 1 . The operation panel 100 transmits the instruction of the tea extraction procedure to the processing module 200 according to the options, and then starts the tea extraction procedure. The processing module 200 controls the tea storage unit 210 for storing green tea to take out 9.5 grams of green tea raw material 400 to the grinding unit 220 for grinding to obtain tea powder of green tea. The tea powder of the ground green tea is sent to the infusion unit 240. Next, the water supply unit 230 provides 15 grams of pre-infusion water at 92° C. to the infusion unit 240, and the processing module 200 controls the infusion unit 240 to infuse the tea powder of green tea with this pre-infusion water for 5 seconds to obtain the first tea liquid of green tea, And the first tea liquid is sent to the cup container 300 .
