(2) Emulsification step: the water inlet needle 5 pierces the membrane 82 of the milk coffee capsule 8 to be inserted into the middle ring 833 , and the drawn out needle 6 pierces the membrane 82 of the milk coffee capsule 8 synchronously and extends into the first cavity 84 , the control board controls the liquid supply mechanism to inject 55ml of water into the milk coffee capsule 8 through the water inlet puncture needle 5 at a flow rate of 13ml/s, so that the water forms a relatively large pressure in the gap between the upper end of the middle ring 833 and the diaphragm 82, and the water is shunted The plate 834 will block the water flow to a certain extent, and form a backsplash effect on the water, so that the water flow will be ejected quickly from the gap between the upper end of the middle ring 833 and the diaphragm 82, and form a vortex in the first cavity 84. Driven by the vortex, it is fully mixed with water and dissolved to form milk;

(3) Extraction step: the control board controls the liquid supply mechanism to inject 88ml of water into the milk coffee capsule through the water puncture needle at a flow rate of 4ml/s, and the water enters the second cavity 85 from the diversion hole 835 and fully infiltrates the coffee powder , to form coffee liquid;

(4) Mixing step: the control board controls the liquid supply mechanism to inject 32ml of water into the milk coffee capsule through the water puncture needle at a flow rate of 13ml/s. The coffee liquid formed in the extraction step is under the pressure of the continuously injected water. The filter paper 832 filters and flows into the first cavity 84, and then fully mixes with the milk to form a milk coffee drink;

(5) Beverage discharge step: the prepared milk coffee drink is drawn out of the milk coffee capsule by drawing out the puncture needle.

The advantage of the above milk coffee drink preparation method is that by setting the milk coffee production method to include an emulsification step, an extraction step and a mixing step, the milk powder is firstly emulsified and brewed in sequence, and then the coffee powder is extracted and filtered, and finally The milk and coffee liquid are mixed to form a milk coffee drink. Compared with the existing preparation method, the milk liquid and the coffee liquid are fully mixed in this method, and the milk liquid will not float on the surface of the coffee liquid, which not only improves the taste of the milk coffee drink, Moreover, the color and appearance of the milk coffee drink are good, which enhances the attractiveness of the milk coffee drink.

In the emulsification step of the above method, under the water velocity and water volume, the water can form a relatively large pressure in the gap between the upper end of the middle ring 833 and the diaphragm 82, and the speed of water entering the first cavity 84 from the gap is greater than that of water. The speed of entering the second cavity 85 from the split hole 835 is such that during the emulsification step, the splitter plate 834 will block the water flow to a certain extent, and form a backsplash effect on the water, so that the water flow first passes between the upper end of the middle ring and the diaphragm 82. The gap between them is quickly injected, and a vortex is formed in the first cavity 84. The milk powder is fully mixed with water and dissolved under the drive of the vortex, which not only ensures the concentration of the milk after brewing, but also improves the dissolution rate of the milk powder, avoiding The waste of milk powder also improves the brewing efficiency and shortens the preparation time of drinks.

In the extraction step of the above method, under this water flow rate and water volume, it can effectively ensure that the coffee powder is fully extracted and will not be over-extracted, so as to ensure that the extracted coffee liquid will not be too bitter and improve the taste of the extracted coffee liquid .

In the mixing step of the above method, under the water flow rate and water volume, it can ensure that the milk liquid and the coffee liquid are fully mixed, and the mixing is fast, and the brewing efficiency of the milk coffee drink is improved.

More specifically, in the emulsification step, the control panel controls the water pump to work at 80%-100% of the rated power, specifically 100%, and after injecting 55ml of water, the water pump stops working for 5 seconds. Since the water pump is working at full power at this time, the water flow speed is fast, so that the water flow can better form a vortex in the first cavity, improve the dissolution rate of the milk powder, and at the same time have the effect of micro-pressure emulsification and improve the formed milk. smoothness of taste. Of course, the water pump can also work at 80%, 85%, 90%, 95%, 96%, 98% and other rated power, depending on the specific situation.

In the extraction step, the control panel controls the water pump to work at 10%-80% of the rated power, specifically 31%, and injects 88ml of water into the second chamber. In this step, the extraction is performed with a smaller power, and the water flow speed is slower. Due to the existence of pressure, the newly entered water will press out the water that soaked the coffee powder and completely replace it, so that the coffee powder can be fully extracted and the extraction efficiency is high. Of course, the water pump can also work at 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80% and other rated power, depending on the specific situation.

In the mixing step, the control board controls the water pump to work at 20%-100% of the rated power, specifically 100%, and continuously injects 32ml of water into the capsule. In this step, the water pump works at full power, and the water flow speeds up, making the coffee liquid Quickly pass through the filter paper and mix with the milk, so that the milk and coffee liquid mix with each other and form a vortex, so that the milk and coffee liquid are fully mixed, which not only improves the taste of the milk coffee drink, but also has high mixing efficiency. Of course, the water pump can also work at 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% and other rated power, depending on the specific situation.

It can be understood that, as shown in Figures 3 and 4, the filter holder 831 is also provided with a surrounding wall 836 located on the outer periphery of the middle ring 833 and extending toward the direction of the diaphragm 82. The surrounding wall 836 is provided with ribs 837, and the ribs 837 are provided with There are many strips and they are all arranged on the inner surface of the surrounding wall 836, so that during the emulsification step and the mixing step, the effect of the milk on the surrounding wall and the ribs can generate better eddy currents, which not only makes the milk during the emulsification step mix It is better, and during the mixing step, the milk liquid and the coffee liquid are mixed more fully, which better improves the taste of the milk coffee drink.

It can be understood that the filter paper can also be other filter elements, such as a filter net and the like.

Embodiment two:

The difference between this embodiment and the first embodiment is that the extraction steps are different, that is, the extraction steps include a staged extraction process.

In this embodiment, the extraction step includes a staged extraction process: the liquid supply mechanism injects a certain amount of water and then stops for a period of time, and then continues to inject water, so that the cycle is N times, N≥2, and the extraction process of each stage in the staged extraction process The interval between them is T, 0.1s≤T≤5s.

Specifically, S2 is 4ml/s, V2 is 88ml, N=11 times, T=2s, so that 88ml of water is injected into the second cavity 84 11 times, each injection is 8ml, and the interval between each injection for 2s.

Specifically, the airflow velocity during the blowing process is S4, 10ml/s≤S4≤30ml/s, specifically, S4 is 12.5m/s, the air is blown by the air pump, and the gas quickly passes through the splitter plate in the middle ring and enters the second Cavity 85, and a certain pressure is formed in the second cavity 85 to push the water absorbed by the coffee powder to quickly pass through the filter paper 832 and mix with the milk in the first cavity 84, which can not only promote the mixing of coffee liquid and milk , and can squeeze out the water absorbed by the coffee powder, increase the concentration of the coffee liquid, and also speed up the discharge efficiency of the milk coffee drink, saving the time for making the drink. When S4 is less than 10ml/s, the airflow velocity is too small, and the blending effect of coffee liquid and milk liquid is weak; when S4 is greater than 30ml/s, the airflow velocity is too high, and the internal pressure of the second cavity is too high, which will cause the filter paper to rupture The coffee powder in the second cavity is caused to enter the first cavity, which affects the taste of the milk coffee drink. The rest of the structure of the milk coffee capsule of this embodiment, the structure of the capsule beverage machine and its effects are consistent with those of Embodiments 1 and 2, and will not be repeated here.

More specifically, the control panel controls the air pump to work at 10%-100% of the rated power, specifically 50%, and the working time is 8 seconds, so that the air pump can work within a reasonable rated power range, which ensures that the air pump can well transfer the beverage Discharge, and will not generate a large pressure, to ensure the normal work of the capsule. Of course, the air pump can also work at 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100% and other rated power, and the working time can also be 1 second , 2 seconds, 3 seconds, 4 seconds, 5 seconds, 6 seconds, 7 seconds, 9 seconds, 10 seconds, etc., depending on the specific situation.

The blowing process in this embodiment is pre-programmed, so that automatic blowing can be realized, and the milk coffee drink can be made with one-key operation. Of course, the blowing button can also be set separately, and the blowing process can be realized by manually pressing the blowing button, so that you can choose to blow or not, depending on the user's habits.

Understandably, S4 can also be 10ml/s, 12ml/s, 14ml/s, 15ml/s, 16ml/s, 18ml/s, 20ml/s, 22ml/s, 24ml/s, 25ml/s, 26ml/s s, 28ml/s, 30ml/s, etc., depending on the specific situation.
