The invention has the beneficial effects that:
the invention discloses a method for preparing foaming beverage by a capsule beverage machine, which comprises a machine base, a brewing head provided with a water inlet pricking pin, a brewing cup used for containing a capsule, a leading-out pricking pin, a liquid supply mechanism and an air supply mechanism, wherein the liquid supply mechanism and the air supply mechanism are both communicated with the water inlet pricking pin, and the method for preparing the foaming beverage comprises the following steps: in the slurry dissolving stage, the liquid supply mechanism introduces liquid flow into the capsule through the water inlet pricker, and the liquid flow dissolves powder in the capsule to form slurry; in the foaming stage, the gas supply mechanism introduces gas into the capsule through the water inlet pricker to promote the slurry to be stirred and rolled in the capsule to form bubbles; in the slurry discharging stage, the liquid supply mechanism introduces liquid flow into the capsule through the water inlet pricker and pushes slurry and air bubbles to be discharged from the extraction pricker.
In the slurry dissolving stage, the liquid flow introduced by the water inlet pricker is used for washing and mixing the powder in the capsule, the dissolved slurry can be filled in the capsule in a short time, and in the process, the original gas in the capsule can be mixed into the slurry to form a small amount of bubbles; in the foaming stage, the gas introduced by the water inlet pricker is utilized to promote the slurry in the capsule to be rolled and beaten, and a large amount of bubbles are formed in the rolling and beating process; in the slurry discharging stage, the liquid flow is introduced again by the water inlet pricker, on one hand, air bubbles and slurry can be promoted to be mixed, certain air can be mixed and embedded in the slurry, and air bubbles with different sizes are formed, on the other hand, the liquid flow dynamic pressure for discharging the air bubbles and the slurry from the leading-out pricker can be provided, the limitation of the flow area of the leading-out pricker is applied, larger air bubbles cannot be discharged or are directly broken, the size of the discharged air bubbles is ensured to be consistent, and finally, the foaming beverage with rich bubbles in a foam layer can be obtained. By adopting the preparation method, the foaming beverage with rich foam can be prepared by using one capsule, so that the complicated preparation process in the prior art is avoided, and the preparation cost of the beverage and the energy consumption of a machine are reduced; compared with the brewing pressure required by the beverage making in the prior art, the invention has a much smaller requirement on the pressure of introduced liquid and gas, can basically realize non-pressure/low-pressure brewing, reduces the pressure requirement on a capsule beverage machine, and ensures the working stability of the machine.
The liquid supply mechanism intermittently works, the gas supply mechanism continuously works, and during the stop work of the liquid supply mechanism, the gas supply mechanism introduces gas into the capsule through the water inlet pricking pin. The liquid supply mechanism works intermittently, the gas supply mechanism still supplies gas continuously during the period that the liquid supply mechanism stops working, the liquid remained in the water inlet pricker is blown into the capsule by the introduced gas, the introduced liquid has higher flow rate, the slurry is promoted to rapidly roll and whip in a small space of the capsule in a short time, and the gas is rapidly injected into the slurry in the capsule through the water inlet pricker in a matching manner, so that the embedding of the slurry on the gas is promoted to generate bubbles, and the stability after the bubbles are formed is facilitated.
The frothing stage and the pulp discharge stage are cycled at least twice. On one hand, the prepared beverage has a thicker foam layer through multiple foaming, on the other hand, the prepared beverage is beneficial to fully dissolving powder in the capsule, and the residue is reduced, so that the prepared beverage can also keep better concentration and mouthfeel on the basis of having rich foam.
The time for stopping the liquid supply mechanism is 0.1 s-2 s. It can be understood that: because the air supply mechanism works continuously, the time for stopping the work of the liquid supply mechanism is the duration time for introducing the gas into the capsule by the water inlet pricker, if the time for stopping the work of the liquid supply mechanism is less than 0.1s, the introduced gas amount is too little to be beneficial to generating bubbles, if the time for stopping the work of the liquid supply mechanism is more than 2s, the introduced gas amount is too much to cause the increase of the internal pressure of the capsule and the risk of bursting the cup, the time for stopping the work of the liquid supply mechanism is 0.1 s-2 s, the safety of beverage making is ensured while reasonable gas amount is provided for foaming, and the work coordination of the liquid supply mechanism and the air supply mechanism is easier to control in such a time period, so that the success rate.
The capsule beverage machine also comprises a driving device for driving the water inlet pricking pin to rotate, and the water inlet pricking pin generates a rotating jet along with the rotation of the water inlet pricking pin when introducing liquid flow or gas into the capsule. The beverage powder is washed by the liquid flow in the rotary jet flow area so as to be mixed and dissolved, the mixing and dissolving of liquid and the beverage powder are accelerated, the beverage powder is fully dissolved without residues, the taste and the nutritional value of the beverage are improved, the water inlet prickling needle forms rotary jet flow motion in the rotation process, the dissolving of the beverage powder is better promoted, the brewing efficiency and the taste of the beverage are improved, particularly for the foaming beverage to be made, the rotary jet flow can promote the quick stirring and the rolling of slurry in a capsule, promote the slurry to embed gas to form bubbles and accelerate the formation of the bubbles, and the non-pressure/low-pressure brewing foaming beverage is more favorably realized by matching with the making method.
The rotating speed of the water inlet pricker in the foaming stage is greater than that of the water inlet pricker in the slurry dissolving stage. The relatively low rotating speed is adopted in the pulp dissolving stage, the requirement of powder dissolving is met, the power consumption and the noise are reduced, the relatively high rotating speed is adopted in the foaming stage, the generation of bubbles is further accelerated, and therefore the whole beverage making time can be shortened.
The temperature of the liquid flow introduced by the water inlet pricker is maintained between 60 and 85 ℃. The invention aims to realize that a capsule is used for preparing a foaming beverage with rich foam, powder with certain protein content is usually mixed in the capsule, and the capsule comprises the following components in percentage by weight: the foaming property of the protein component is in direct proportion to the temperature, the foam stability is in inverse proportion to the temperature, the foaming property of the protein component is in a linear rising trend under the condition of 20-90 ℃, the foam stability is in a slow falling trend under the condition of 20-80 ℃, and is in a remarkable falling trend after the temperature exceeds 80 ℃, so that the temperature of liquid flow is maintained at 60-85 ℃, the good foaming property is ensured, and the higher foam stability can be maintained.
The flow rate of the liquid flow introduced into the capsule by the water inlet puncture needle is 10 mL/s-20 mL/s. Because the powder is usually deposited at the bottom of the capsule cup, the powder needs to be scattered by the liquid flow injected by the water inlet pricker and is promoted to be dissolved, the flow velocity of the liquid flow introduced by the water inlet pricker directly influences the beverage brewing effect, if the flow velocity of the liquid flow is lower than 10mL/s, the liquid flow scouring force is insufficient, the powder cannot be fully dissolved, the liquid flow kinetic energy is insufficient, the whipping effect is weakened, and the frothing amount is not ideal enough; if the flow rate of the liquid flow is higher than 20mL/s, the working requirement on the liquid supply mechanism is high, the flow rate of the liquid flow is difficult to maintain stably, and under the condition of a certain liquid flow, the excessively high flow rate of the liquid flow is unfavorable for uniformly dissolving the powder in the capsule cup, so that the flow rate of the introduced liquid flow is limited to 10 mL/s-20 mL/s, and thus, the stable and continuous liquid flow can be provided to uniformly and fully dissolve the powder in the capsule, and further, sufficient slurry is provided for bubbles.
The flow rate of the air flow introduced into the capsule by the water inlet pricker is 20mL/min to 30 mL/min. In the foaming stage, the generation of bubbles in the capsule depends on the introduction of external gas, so the flow rate of the introduced gas flow directly influences the foaming effect, if the flow rate of the introduced gas flow is lower than 20mL/min, the amount of gas introduced into the capsule in unit time is small, the amount of bubbles formed and embedded by the slurry per se is insufficient, the obtained foam layer is not thick enough, if the flow rate of the introduced gas flow is higher than 30mL/min, the amount of gas introduced in unit time is too large, the internal pressure of the capsule is increased, the risk of cup explosion is caused, and the flow rate of the introduced gas flow is limited to be 20 mL/min-30 mL/min, so that stable and safe gas flow can be provided to promote the slurry in the capsule to be stirred and stirred to form bubbles.
The capsule beverage machine provided by the invention adopts the method for preparing the foaming beverage by the capsule beverage machine provided by the invention, the capsule comprises a capsule cup and a capsule membrane for sealing the mouth of the capsule cup, and a boss for reflecting liquid flow is arranged on the bottom wall of the capsule cup. In the process of making the beverage, the dynamic pressure of jet flow pushes the slurry to collide with the lug boss on the bottom wall of the capsule cup to be reflected, so that the liquid flow is fully diffused to increase the dissolving area, the powder in the capsule is fully and uniformly dissolved, and the requirements on the jet flow and the flow rate introduced by the injection hole of the water inlet pricker can be reduced. By matching with the method for preparing the foaming beverage by the capsule beverage machine, the foaming beverage with uniform taste and concentration and rich foam can be prepared.
These features and advantages of the present invention will be disclosed in more detail in the following detailed description and the accompanying drawings.
