The method for preparing the beverage according to the embodiment of the present invention is described with reference to fig. 1 to 10, and is suitable for preparing beverages such as fruit juice and soybean milk.

Referring to fig. 1, the beverage preparation method of the embodiment of the present invention includes, but is not limited to, the following steps:

step S100, rotating the container loaded with the slurry to carry out centrifugation, so that at least part of slag in the slurry is adhered to the inner wall of the container, and separating the slag.

It can be understood that the beverage preparation method of the embodiment is applied to the food processor 1000, and the food processor 1000 is provided with a rotatable container, so that the slurry to be filtered is subjected to centrifugal treatment, and the material residue can be rapidly separated. Specifically, the container filled with the slurry is driven to rotate at a high speed for centrifugation, at least part of the slag in the slurry can be adhered to the inner wall of the container under the action of centrifugal force, and the slurry in the slurry can flow back to the bottom of the container, so that the slag is separated, and the separation of the slag and the slurry is realized.

The slurry is a mixture of the slag and the slurry obtained by crushing, grinding and the like, and the slag is a particulate matter such as food residue, and the slag needs to be separated from the slurry in order to achieve a better drinking taste. It is understood that the prepared slurry may be poured into a container for centrifugal treatment, or the foodstuff may be treated in the container to obtain the slurry, which is not further limited herein. In the centrifugation process, when the rotating speed of the container is large enough, centrifugal force can be generated on slurry, at least one part of material slag can be adhered to the inner wall of the container, so that the material slag is separated, and after the centrifugation is finished, the material slag adhered to the inner wall is separated from the slurry, so that the purpose of separating the material slag from the slurry is achieved. It is easy to understand that the larger the rotating speed of the container is, the more the amount of the material slag adhered to the inner wall of the container is, the better the effect of separating the material slag is, and the better the drinking taste of the slurry is.

It can be understood that the dregs of the foodstuff are mostly insoluble dietary fibers, the dregs are mixed in the slurry, and the dregs have certain viscosity and can be tightly attached to the inner wall of the container under the centrifugal state. For example, the foodstuff can be fruit, and fruit is broken and behind centrifugal treatment, and the pomace can adhere to the container inner wall, makes pomace and fruit juice quickly separating to can pour direct drinking with fruit juice from the container, the pomace then remains the container in, need not manually to filter, can obtain comparatively pure fruit juice. For another example, the slurry can be soybean milk, after centrifugal treatment, the bean dregs are adhered to the inner wall of the container, and the bean dregs and the slurry are separated, so that the soybean milk with the filtered bean dregs is obtained, manual filtration is not needed, and the soybean milk has better drinking taste.

Referring to fig. 2, the beverage preparation method according to the embodiment of the present invention includes, but is not limited to, the following steps:

step S110, crushing the foodstuff in the container to obtain slurry.

And step S120, rotating the container for centrifugation, wherein at least part of the material slag is adhered to the inner wall of the container to separate the material slag.

It will be appreciated that the foodstuff is subjected to a crushing process prior to the centrifugation process to obtain a slurry. Specifically, at first put into the container with the foodstuff in, utilize cooking machine 1000 to carry out the breakage to the foodstuff, the foodstuff obtains the ground paste after the broken handle, then cooking machine 1000 drive container high-speed rotation carries out the centrifugation, makes the material sediment in the ground paste can the adhesion on the inner wall of container under the centrifugal force effect, and the bottom of container can be refluxed to the thick liquid in the ground paste to with the separation of material sediment, realize material sediment and thick liquid separation.

It should be noted that the food processor 1000 may be understood as an electric appliance capable of making various foods such as fruit juice, soybean milk, jam, meat paste, etc., and the food processor 1000 may crush food materials in the container to make the food materials crushed into slurry. For traditional cooking machine, the container can rotate, has the centrifugal processing function, for example, it is rotatory to utilize motor drive container, under the high-speed rotation state, produce centrifugal force in the container for the material sediment is kept away from the center of container and is hugged closely on the inner wall of container under the centrifugal force effect, the material sediment can the adhesion at the container inner wall, and the thick liquid can flow back to the container bottom, thereby separate out the material sediment from the thick liquid, and like this, the thick liquid can directly pour out the container, and the material sediment can the adhesion on the container inner wall, realize material sediment and thick liquid separation.

In the embodiment, in the step of crushing the foodstuff in the container, the foodstuff in the container is crushed by the knife set 130 of the food processor 1000, and the knife set 130 rotating at a high speed can chop the foodstuff into slag. It is easily understood that, when the knife set 130 is operated, the container is stationary and does not rotate, so that the knife set 130 is in sufficient contact with the foodstuff to be crushed, the container rotates to be centrifuged after crushing, the knife set 130 does not rotate during centrifugation, or the knife set 130 is detached from the container and centrifuged. In addition, the crushing step is not limited to crushing by the cutter set 130, and may also be a process technique such as grinding and crushing, and will not be described herein again.

It is understood that the feed is not limited to one type and may be prepared by combining different feeds, for example, soy with millet. Aiming at the difficulty degree of different material crushing, the user can properly prolong the crushing time, or put different foodstuff into the container in batches, which is beneficial to improving the crushing effect and making the centrifugal separation effect better.

Taking soymilk making as an example, the soymilk preparation method includes, but is not limited to, the following steps:

step S111, adding soybeans and water into a container, and crushing the soybeans to obtain soybean milk;

and step S121, rotating the container for centrifugation, wherein at least part of the bean dregs are adhered to the inner wall of the container so as to separate the bean dregs.

It can be understood that the soybean in the container is directly crushed to obtain the raw soybean milk, and compared with the traditional soybean milk making process, the embodiment of the invention adopts the centrifugal technology to separate the soybean milk from the bean dregs, realizes automatic separation and does not need manual filtration; after centrifugal treatment, insoluble dietary fibers, bean skins and other substances which cannot be digested and absorbed in the soybean milk are separated, at least part of bean dregs can be stuck on the inner wall of the container, the soybean milk is directly poured out of the container to be heated, and the soybean milk can be blended and drunk according to the taste after being heated, so that the bean dregs are effectively removed, the taste of the soybean milk can be improved, and the problems of dyspepsia and the like caused by the insoluble dietary fibers of macromolecules such as the bean skins can be avoided.

It should be noted that, the adopted container can be a cup body 110 structure, considering that slurry in the cup body 110 can move upwards along the inner wall in the centrifugal process, the cup body 110 with a conical inner cavity can be adopted in the embodiment, and the inner cavity of the cup body 110 is gradually narrowed from bottom to top, so that material slag can be adhered along the inner wall in the centrifugal process, and the slurry can be concentrated at the bottom of the cup body 110, thereby being beneficial to the centrifugal balance, ensuring the centrifugal stability and the centrifugal separation effect to be better.

It can be understood that, under the condition that the rotating speed of the cup body 110 is large enough, the slurry in the cup body 110 is tightly attached to the inner wall under the action of centrifugal force, after a certain period of centrifugal treatment, the slag can be adhered to the inner wall, and the slurry can flow back to the bottom of the cup body 110, so that the slag is separated from the slurry, and the purpose of separating the slag from the slurry is achieved. In the centrifugal treatment process, the rotating speed of the cup body 110 is 500 to 5000 revolutions per minute, different rotating speeds can be selected for centrifugal treatment according to the quantity and the type of foodstuff, the centrifugal time is controlled between 0.5 to 10 minutes, and the centrifugal time is understood to be long enough, so that the good slurry-residue separation effect can be ensured. For example, after the foodstuff is crushed to form slurry, the cup body 110 is controlled to rotate at a rotating speed of 3000 revolutions per minute, the centrifugal time is 3 minutes, most of the material slag can be adhered to the inner wall of the cup body 110 after centrifugal treatment, automatic separation of the material slag and the slurry is realized, manual operation is not needed, and the slurry-slag separation effect is remarkable.

Referring to fig. 3, in the embodiment, the beverage preparation method includes, but is not limited to, the following steps:

step S130, heating food in the container;

step S140, crushing foodstuff to obtain slurry;

and step S150, rotating the container for centrifugation, wherein at least part of the slag is adhered to the inner wall of the container so as to separate the slag.

It will be appreciated that the foodstuff is heated prior to the rotating vessel being centrifuged, and this is suitable for foodstuffs which require heating. The food processor 1000 of adoption has the heating function. Specifically, foodstuff in the container is heated, then the foodstuff is crushed, the foodstuff is subjected to crushing treatment to obtain slurry, and finally the container is driven to rotate at a high speed for centrifugation, so that material residues are separated from slurry, the separated slurry can be directly drunk, and the cooking is performed without extra heating. Wherein, heat time and heating temperature can be set for according to different foodstuff, to the difficult degree of cooking of different materials, can throw in different foodstuff in turn to the container, can enough guarantee the nutritive value of foodstuff, can improve the slurrying effect again. For example, when soybean milk is prepared, soybeans are boiled and boiled for a period of time, the heated and boiled soybeans are more easily broken, and the soybean milk preparing effect is better.

It is considered that the sludge adheres to the inner wall of the vessel after the centrifugal treatment of the slurry, and the bottom is easily burnt by heating. Therefore, in the method of the embodiment, the foodstuff is heated before the centrifugal treatment, the material residue is separated from the slurry through the centrifugation, and the slurry can be poured out from the container for direct drinking without manual filtration. It is to be understood that the steps of heating the foodstuff and crushing are not limited to the order shown in the examples, and the foodstuff may be crushed and then heated.

Referring to fig. 4, a preparation method of soymilk is exemplified and includes, but is not limited to, the following steps:

step S131, adding soybeans and water into a container and heating;

step S141, crushing soybeans to obtain slurry;

and step S151, rotating the container for centrifugation, wherein at least part of the bean dregs are adhered to the inner wall of the container to separate the bean dregs.

Wherein, the heating process needs to thoroughly cook the soybeans so as to eliminate trypsin blocking factors in the soybeans and ensure the edible safety of the soybean milk. Specifically, the soybeans are cleaned, impurities are removed, dust, stains and the like on the surfaces of the soybeans are cleaned, the cleaned soybeans are placed into a container, a certain amount of water is added, then the processor 1000 starts to work, the soybeans and the water are heated, boiled and continuously heated for a preset time, and then the soybeans are crushed, so that pulping is completed; and finally, controlling the container to rotate at a high speed for centrifugal treatment, and adhering bean dregs to the inner wall of the container under the action of centrifugal force, so that the bean dregs are separated out, the separation of the bean dregs and the soybean milk is realized, the soybean milk can be directly poured out from the container for drinking, the soybean milk has better taste, is simple to operate, does not need manual filtration, is more convenient to clean, and avoids the problems of easy scald caused by manual filtration, complex operation and the like.

It can be understood that, in the step of heating the foodstuff, different heating powers can be adopted for heating treatment, for example, different heating powers are adopted for different foodstuffs, so that the nutritional value of the foodstuff can be ensured, and the pulping effect can be improved; for another example, in the heating process, different heating powers are adopted for heating alternately, so that the heating effect is better, the problem of bottom pasting is avoided, and the nutritive value of food and better drinking mouthfeel are ensured.

It should be noted that, when making soybean milk, the soybean is processed with water according to a certain proportion, other foodstuff can be added for matching, the soybean milk is obtained after crushing, then the soybean milk is processed centrifugally, the rotating speed of the container is controlled to be more than 3000/min, and the centrifugal time is controlled to be more than 1 min, so that most of the bean dregs can be adhered to the inner wall of the container, the bean dregs and the milk are effectively separated, and the pure soybean milk is obtained without manual filtration and has better drinking taste.

It will be appreciated that different heating powers may be used to heat the foodstuff in order to increase the heating efficiency. Specifically, when in heating, the foodstuff is heated by first heating power, the foodstuff is heated to a boiling state, then the foodstuff is heated by second heating power, and the foodstuff is continuously heated and boiled by the second heating power, wherein the first heating power is greater than or equal to the second heating power, the first heating power can be understood as high power, and the heating time of the first heating power can be set as first preset time; the second heating power can be understood as low power, and the heating time of the second heating power can be set as a second preset time, namely, the heating process adopts high power to heat for a first preset time, and then adopts low power to heat for a second preset time. Different first heating power and second heating power and first preset time and second preset time are set for different food materials, and the nutritive value of the food materials can be guaranteed. Certainly, the first heating power and the second heating power can be alternately heated, the pulping period can be shortened, bottom pasting is effectively avoided, and the pulping effect is improved.

Referring to fig. 5, in an embodiment, step S130 includes, but is not limited to, the following steps:

step S132, after the soybeans and the water are heated to a boiling state by the first heating power, the soybeans and the water are boiled by the second heating power.

Wherein the first heating power has a power value of 800W to 2500W, the first heating power is heated for 5 seconds to 60 seconds, the second heating power has a power value of 50W to 800W, and the second heating power is heated for 5 minutes to 60 minutes. For example, 30g of soybeans are weighed, the soybeans and water are added into a container according to the weight ratio of 1:10, the soybeans and the water are heated by adopting 1500W of heating power, the soybeans and the water are boiled to be boiling after being heated for 1 minute, then the soybeans are heated by adopting 500W of heating power, the heating time is 15 minutes, crushing treatment is carried out after the boiling, the crushing effect is favorably improved, the prepared soybean milk is higher in rate, and the drinking taste is better.

It will be appreciated that the foodstuff may be heated by different heating powers, and that the foodstuff may be heated first and then broken and then heated. Specifically, adopt first heating power to heat the foodstuff to the boiling state after, carry out the breakage to the foodstuff, then adopt second heating power to heat the foodstuff through crushing treatment, for example, adopt 1500W's heating power to heat soybean and water, heat to carrying out the breakage to the soybean after the boiling, then utilize 500W's heating power to boil out, carry out centrifugal treatment again after the completion of boiling to make bean dregs and soybean milk separation, make the soybean milk finished product. The soybean boiled by heating is more easily crushed, the crushing efficiency is improved, the particles obtained by crushing the soybean are smaller, and the soybean is heated after being crushed, so that the soybean milk yield is more favorably improved, the extraction rate of the soybean protein and the soybean isoflavone is higher, and the pulping effect is better.

Referring to fig. 6, in an embodiment, the heating and crushing steps include, but are not limited to, the following:

step S133, heating the soybeans and water to a boiling state with a first heating power;

step S134, crushing soybeans to obtain slurry;

and step S135, boiling the slurry with a second heating power.

It should be noted that the foodstuff can be made into slurry after being crushed, and when the slurry is heated by adopting the second heating power, the slurry needs to be stirred, so that bottom pasting can be avoided. It can be understood that the higher the concentration of the slurry is, the more easily the bottom pasting phenomenon occurs, therefore, the low power is adopted for heating in the boiling process, the slurry is stirred, the bottom pasting is effectively prevented, the soybean milk with higher protein content is obtained, and the pulping effect is better.

In addition, the heating time of the soybean is controlled to be more than 5 minutes according to the preparation method of the soybean milk, so that the purpose of eliminating trypsin blocking factors in the soybean is achieved, the specific heating time is set according to the weight of the soybean, and the heating time is between 5 minutes and 60 minutes. For example, the beans and water are boiled for 1 minute by 1500W heating, then crushed at a high speed for 3 minutes by 3000 rpm, and then continuously heated for 20 minutes by 500W, thereby completing pulping; and finally, the container is controlled to rotate at a high speed for centrifugal treatment, bean dregs and the soybean milk are separated, manual filtration is not needed, and the preparation of the soybean milk is more efficient.

It can be understood that, in the embodiment, the foodstuff is heated in the crushing process, so that the crushing effect can be further improved, particularly, in the soybean milk preparation process, the heating is carried out in the crushing process, the soybeans can be crushed more easily, the efficiency is higher, and the pulping effect is further improved.

It should be noted that the heating power used in the crushing process may be high power or low power, for example, referring to fig. 7, step S140 may include the following steps:

step S142, crushing the soybeans at a rotating speed of 3000 revolutions per minute for 1 minute when the soybeans are crushed;

and step S143, heating by 1500W for 1 minute, and then continuing crushing for 1 minute.

It can be understood that the crushing and heating steps can also be performed simultaneously, i.e. heating while crushing, for example, crushing soybeans at 3000 rpm, and heating with 500W of heating power, so that the heating and crushing are performed simultaneously, which is not only beneficial to improving the crushing effect, but also can avoid the bottom-pasting phenomenon during heating.

Referring to fig. 8, in some embodiments, the beverage preparation method includes, but is not limited to, the following steps:
