The beverage preparation method 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 juice, soybean milk, and the like.

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

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

It will be appreciated that the beverage preparation method of the embodiment is applied to a food processor 1000, and the food processor 1000 has a rotatable container, and the slurry to be filtered is centrifuged, so that the material and the residue can be separated rapidly. 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 the 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 slag is separated from the slurry.

The slurry may be a mixture of the residue obtained by crushing, grinding, or the like, and the slurry, and the residue may be particulate such as food residue, or the like, and the residue may be separated from the slurry for a good drinking taste. It will be appreciated that the slurry thus produced may be poured into a vessel for centrifugation, or the foodstuff may be treated in the vessel to provide a slurry, which is not further limited herein. In the centrifugation process, when the rotating speed of the container is large enough, centrifugal force is generated on the slurry, so that at least part of the slag can be adhered to the inner wall of the container, the slag is separated from the slurry, and the slag adhered to the inner wall is separated from the slurry after the centrifugation is finished. It is easy to understand that the larger the rotation speed of the container is, the more slag is adhered to the inner wall of the container, the better the slag separating effect is, and the better the drinking taste of the slurry is.

It is understood that the residue of foodstuff, which is mostly insoluble dietary fibers, is mixed in the slurry, has a certain viscosity and can be tightly attached to the inner wall of the container in a centrifugal state. For example, the foodstuff may be fruit, the fruit is crushed and centrifuged, the pomace adheres to the inner wall of the container, so that the pomace and the juice are rapidly separated, the juice can be poured from the container for direct drinking, the pomace remains in the container, and the purer juice can be obtained without manual filtration. For another example, the slurry can be soybean milk, and after centrifugal treatment, the bean dregs are adhered to the inner wall of the container, and the bean dregs are separated from the slurry, so that the soybean milk with the bean dregs filtered 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:

And 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 slag adheres to the inner wall of the container so as to separate the slag.

It will be appreciated that the foodstuff is crushed to give a slurry prior to centrifugation. Specifically, firstly, foodstuff is put into a container, the foodstuff is crushed by using a food processor 1000, slurry is obtained after the foodstuff is crushed, then the food processor 1000 drives the container to rotate at a high speed for centrifugation, the material 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 material slag is separated, and the separation of the material slag and the slurry is realized.

The food processor 1000 is understood to be an electric appliance capable of producing various foods such as fruit juice, soybean milk, jam, and meat stuffing, and the food processor 1000 is capable of crushing the foods in the container to crush the foods into slurry. Compared with a traditional food processor, the container can rotate and has a centrifugal treatment function, for example, the container is driven by a motor to rotate, and under the high-speed rotation state, centrifugal force is generated in the container, so that the slag is far away from the center of the container and is clung to the inner wall of the container under the action of the centrifugal force, the slag can be adhered to the inner wall of the container, and the slurry can flow back to the bottom of the container, so that the slag is separated from the slurry, and therefore, the slurry can be directly poured out of the container, and the slag can be adhered to the inner wall of the container, so that the slag and the slurry are separated.

In an 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 cut the foodstuff into slag. It will be readily appreciated that when the knife set 130 is in operation, the container is stationary and not rotated, so that the knife set 130 is fully in contact with foodstuff for crushing, and after crushing, the container is rotated for centrifugation, and the knife set 130 is not rotated during centrifugation, or the knife set 130 is removed from the container and then centrifuged. In addition, the crushing step is not limited to the crushing by the knife set 130, and may also employ the process technologies such as grinding crushing, extrusion crushing, etc., which will not be described herein.

It will be appreciated that the foodstuff is not limited to one type and may be pulped with a different foodstuff mix, for example, soy with millet mix. According to the crushing difficulty of different materials, a user can properly prolong the crushing time, or put different foodstuff into the container in batches, so that the crushing effect is improved, and the centrifugal separation effect is better.

Taking soymilk preparation as an example, soymilk preparation methods include, but are not limited to, the following steps:

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

In step S121, the rotating container is centrifuged, and at least part of the okara adheres to the inner wall of the container to separate the okara.

It can be understood that soybeans in a container are directly crushed to obtain raw soybean milk, and compared with the traditional soybean milk manufacturing process, the embodiment of the invention adopts a centrifugal technology to separate the soybean milk from the soybean dregs, thereby realizing automatic separation without manual filtration; after centrifugal treatment, substances which cannot be digested and absorbed, such as insoluble dietary fibers, bean hulls and the like, in the soybean milk are separated, at least part of bean dregs are adhered to the inner wall of the container, the soybean milk is directly poured out of the container and heated, and the soybean milk can be prepared 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 macromolecular insoluble dietary fibers, such as the bean hulls and the like can be avoided.

It should be noted that, the container that adopts can be cup 110 structure, considers in the centrifugation in-process, and thick liquid in the cup 110 can be along inner wall upward movement, and the embodiment can adopt the cup 110 that the inner chamber is the toper, and the inner chamber of cup 110 is narrowed gradually from bottom to top, can make the material sediment follow the inner wall adhesion in the centrifugation like this, and thick liquid can concentrate in cup 110 bottom, is favorable to the balance at the centrifugation, makes the centrifugation more stable, and the centrifugation separation effect is better.

It can be understood that the slurry in the cup 110 is tightly attached to the inner wall under the action of centrifugal force under the condition that the rotation speed of the cup 110 is large enough, after a certain period of centrifugal treatment, the slag can be attached to the inner wall, and the slurry can flow back to the bottom of the cup 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 rotation speed of the cup body 110 is 500-5000 rpm, different rotation speeds can be selected for centrifugal treatment according to the amount and the type of foodstuff, the centrifugal time is controlled to be between 0.5 and 10 minutes, and the centrifugal time is understood to be long enough, so that a better slurry-slag separation effect can be ensured. For example, after foodstuff is crushed to form slurry, the cup 110 is controlled to rotate at a rotation speed of 3000 rpm, the centrifugation time is 3 minutes, most of the material slag can be adhered to the inner wall of the cup 110 after the centrifugation 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 an embodiment, the beverage preparation method includes, but is not limited to, the following steps:

Step S130, heating the foodstuff in the container;

Step S140, crushing foodstuff to obtain slurry;

And S150, rotating the container for centrifugation, wherein at least part of the slag adheres to the inner wall of the container so as to separate the slag.

It will be appreciated that the foodstuff is heated prior to centrifugation of the rotating container, and is suitable for foodstuff that requires heating. The food processor 1000 has a heating function. Specifically, foodstuff in the container is heated, then the foodstuff is crushed, slurry is obtained after the foodstuff is crushed, finally the container is driven to rotate at a high speed for centrifugation, so that the material slag and the slurry are separated, and the separated slurry can be directly drunk without additional heating for boiling. Wherein, heating time and heating temperature can be set for according to different foodstuff, to the degree of difficulty of cooking of different materials, can put in the container with different foodstuff batch, can enough guarantee the nutritive value of foodstuff, can improve slurrying effect again. For example, when soybean milk is prepared, soybean is boiled and boiled for a period of time, and the soybean boiled by heating is more likely to be broken, so that the pulping effect is better.

In addition, considering that the slag adheres to the inner wall of the vessel after the slurry is centrifuged, the bottom of the paste is likely to occur when the heating is performed. Thus, in the method of the example, the foodstuff is heated prior to centrifugation, and the residue is separated from the slurry by centrifugation, and the slurry is poured from the container for direct consumption without manual filtration. It will be appreciated that the foodstuff heating step and the crushing step are not limited to the sequence shown in the examples, but the foodstuff may be crushed and then heated.

Referring to fig. 4, a method for preparing soymilk is illustrated as an example, including but not limited to the following steps:

step S131, adding soybean 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 so as to separate the bean dregs.

Wherein, the soybean is thoroughly cooked in the heating process to eliminate trypsin blocking factors in the soybean, so as to ensure the edible safety of the soybean milk. Specifically, firstly cleaning soybeans, removing impurities, cleaning dust, stains and the like on the surfaces of the soybeans, putting the cleaned soybeans into a container, adding a certain amount of water, then starting the operation of the food processor 1000, heating the soybeans and the water, boiling and continuously heating for a preset time, and crushing the soybeans to finish pulping; finally, the container is controlled to rotate at a high speed for centrifugal treatment, and bean dregs are adhered to the inner wall of the container under the action of centrifugal force, so that the bean dregs are separated, the separation of the bean dregs and the soybean milk is realized, the soybean milk can be directly poured out of the container for drinking, the soybean milk has good taste, the operation is simple, manual filtration is not needed, the cleaning is more convenient, and the problems of easy scalding, complex operation and the like due to manual filtration are avoided.

It can be appreciated that in the step of heating the foodstuff, different heating powers may be used for the heating treatment, for example, different heating powers are used for different foodstuff, so that the nutritional value of the foodstuff can be ensured, and the pulping effect can be improved; for 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, the nutritional value of the foodstuff is ensured, and the beverage has better drinking taste.

When the soybean milk is prepared, the soybean and the water are treated according to a certain proportion, other foodstuffs can be added for matching, the soybean milk is obtained after crushing treatment, then the soybean milk is subjected to centrifugal treatment, the rotating speed of the container is controlled to be more than 3000/min, the centrifugal time is controlled to be more than 1 min, and most soybean residues can be adhered to the inner wall of the container, so that the soybean residues and the slurry are effectively separated, and the purer 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, during heating, the foodstuff is heated by using first heating power, the foodstuff is heated to a boiling state, and then the foodstuff is heated by using second heating power, so that the foodstuff is continuously heated by the second heating power for boiling, wherein the first heating power is larger 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 to be a 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 to be a second preset time, that is, the heating process adopts high power to heat the first preset time, and then adopts low power to heat the second preset time. Different first heating power and second heating power and first preset time and second preset time are set for different foods, so that the nutritional value of the foods can be ensured. Of course, the first heating power and the second heating power can be alternatively heated, so that the pulping period can be shortened, the occurrence of 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:

in step S132, the soybean and water are heated to boiling state by the first heating power, and then boiled by the second heating power.

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

It will be appreciated that the foodstuff may be heated by different heating powers, and may be crushed and then heated. Specifically, the foodstuff is heated to a boiling state by adopting a first heating power, then the foodstuff is crushed, then the crushed foodstuff is heated by adopting a second heating power, for example, soybean and water are heated by adopting a heating power of 1500W, the soybean is crushed after the foodstuff is heated to boiling, then the foodstuff is boiled by utilizing a heating power of 500W, and then the foodstuff is centrifuged after the boiling is finished, so that bean dregs and soybean milk are separated, and a soybean milk finished product is prepared. The soybeans boiled by heating are easier to crush, the crushing efficiency is improved, the particles obtained by crushing the soybeans are smaller, and the soybeans are heated after being crushed, so that the soybean milk yield is improved, the extraction rate of soybean protein and 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 steps:

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

Step S134, crushing soybeans to obtain slurry;

In step S135, the slurry is boiled with the second heating power.

The foodstuff is crushed to form slurry, and when the slurry is heated by the second heating power, the slurry is stirred, so that occurrence of paste bottom can be avoided. It can be understood that the higher the concentration of the slurry is, the easier the phenomenon of the paste bottom is, so that the low power is adopted for heating in the boiling process, and the paste bottom is effectively prevented by stirring the slurry, so that the soybean milk with higher protein content is also obtained, and the pulping effect is better.

In addition, according to the preparation method of the soybean milk, the heating time of the soybean is controlled to be more than 5 minutes, the aim of eliminating trypsin blocking factors in the soybean is fulfilled, 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, beans and water are boiled with 1500W heating for 1 minute, then crushed for 3 minutes with a rotation speed of 3000 rpm, and then heated with 500W for 20 minutes, thereby completing pulping; finally, the container is controlled to rotate at a high speed for centrifugal treatment, the bean dregs are separated from the soybean milk, manual filtration is not needed, and the soybean milk preparation is more efficient.

It can be appreciated that in the embodiment, the foodstuff is heated during the crushing process, so that the crushing effect can be further improved, particularly for the soybean milk preparation process, the soybean is crushed while being heated, so that the soybean is 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 may be high power or low power, for example, referring to fig. 7, step S140 may include the following steps:

step S142, when soybean is crushed, the soybean is crushed at a rotating speed of 3000 rpm for 1 minute;

In step S143, 1500W is used for heating, and crushing is continued after heating for 1 minute, wherein the crushing time is 1 minute.

It is understood that the crushing and heating steps may be performed simultaneously, i.e. while crushing and heating, for example, when crushing soybeans at a rotation speed of 3000 rpm, heating is performed by using heating power of 500W, so that the heating and crushing are performed simultaneously, which is beneficial to improving the crushing effect and avoiding the occurrence of a 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:

step S160, heating the slurry in the container;

in step S170, the rotating container is centrifuged, and at least part of the slag adheres to the inner wall of the container to separate the slag.

It can be understood that the slurry to be filtered can be heated first and then centrifuged, so that the rapid separation of the discharged slag can be realized, and the specific process is not repeated. The separated slurry can be directly drunk without additional heating.

In step S161, the slurry is stirred at a rotation speed of 50 to 200 rpm when the slurry is heated.

It is understood that the stirring process may be performed by using a stirrer of the food processor 1000, for example, the motor 210 drives the stirrer to stir; the stirring may be performed manually, by holding the stirrer while heating, or at regular time intervals. In the embodiment, the stirring process can be performed by using the cutter set 130, and when the cutter set 130 breaks, the rotation speed of the cutter set 130 is higher, so that the foodstuff can be quickly cut up; and the stirring effect can be achieved when the cutter set 130 rotates at a low speed, so that the stirring efficiency is higher. The stirring speed of the cutter set 130 can be adjusted according to the slurry concentration, for example, when the slurry concentration is too high, the stirring speed can be adjusted to be increased.

In an embodiment, the rotation speed of the cutter set 130 during crushing is in the range of 100 to 3000 rpm, and the rotation speed of the cutter set 130 during stirring is in the range of 50 to 200 rpm, wherein the crushing time is controlled in the range of 0.2 to 2 minutes. For example, soybean and water are heated with high power, the soybean is crushed with a rotating speed of 3000 rpm after the soybean is heated to boiling, the slurry is boiled with low power after the soybean is crushed for 2 minutes, the slurry is stirred with a rotating speed of 100 rpm during boiling, and centrifugal treatment is carried out after boiling, so that soybean residues and soybean milk are separated to prepare a soybean milk finished product, a higher soybean milk yield is ensured, the extraction rate of soybean protein and soybean isoflavone is improved, and the pulping effect is better.

When making soybean milk, the weight ratio of soybean to water is 1:2 to 1:15, and can be prepared according to the tastes of users. For example, 50g of soybean is selected, the soybean is cleaned, the soybean and water are added into a container according to the weight ratio of 1:10, then the steps of heating, crushing, boiling and centrifuging are carried out, and after the centrifuging treatment, the bean dregs and the soybean milk can be separated, so that a soybean milk finished product is prepared, manual soybean milk filtration is not needed in the preparation process, and the use experience of a user is high.

In the embodiment, when the slurry is required to be processed, the driving device is controlled by the controller to drive the container to rotate, and the slurry is subjected to centrifugal processing, so that at least part of the slurry in the slurry can be adhered to the inner wall of the container, and the slag is separated from the slurry, so that the slag and the slurry slag are separated, the filtering is not required to be performed by manual operation, the efficiency is higher, and the device is applicable to making beverages such as juice and soybean milk.

Referring to fig. 11, a food processor 1000 shown in fig. 11 is illustrated as a specific example, and the food processor 1000 includes a body 200 and a cup assembly 100, the cup assembly 100 being mounted to an upper end of the body 200. The cup assembly 100 includes a cup 110 and a rotating shaft 120, where the cup 110 can be understood as a container in the above embodiment, and a cavity 111 is formed in the cup 110, and the cavity 111 is used for accommodating foodstuff to be processed. The upper end of holding chamber 111 is equipped with the opening, and the user can pack into the foodstuff that needs to arrange through the opening, also can pour out foodstuff or the ground paste after arranging in holding chamber 111, still can wash the inner wall of cup 110 through the opening, and its convenient to use also is convenient for wash.

It is understood that the rotating shaft 120 may be fixedly connected to the cup 110, or may be connected by a clutch device (such as a one-way bearing, or other structures capable of controlling the rotating shaft 120 and the cup 110 to be fixed or separated), and the rotating shaft 120 may drive the cup 110 to rotate along a first direction, which is clockwise or counterclockwise, which is not limited herein. When the cup body 110 rotates, the slurry in the containing cavity 111 contacts with the inner wall of the cup body 110 under the action of centrifugal force, the slag in the slurry after centrifugation is adhered to the inner wall of the cup body 110, and the slurry flows back to the bottom of the containing cavity 111, so that the slag is separated from the slurry, the separation of the slurry from the slag is realized, the slurry and slag separation effect is good, and the taste of the slurry is improved. And the slurry after centrifugal filtration can be poured out from the opening at the upper end of the container 111, so that the slurry can be easily poured out, however, the residue remains in the cup 110, and the cup 110 is convenient to use and clean without manual operation.

It should be noted that, when the controller controls the cup 110 to rotate for centrifugal treatment, the rotation speed of the cup 110 ranges from 500 rpm to 5000 rpm, and the centrifugal time can be controlled between 0.5 min and 10 min according to the amount and the type of the foodstuff, so that the centrifugal time is long enough to ensure a better separation effect. For example, after soybean is crushed to form slurry, the cup 110 is controlled to rotate at a rotating speed of 3000 rpm, the centrifugation time is 2 minutes, and after the centrifugation treatment, bean dregs can be adhered to the inner wall of the cup 110, so that the bean dregs are separated out, manual operation is not needed, and the slurry-dreg separation effect is remarkable.

Referring to fig. 11, in order to enhance the centrifugal processing effect, the cup 110 generally has an upwardly narrowed structure. It is understood that, along the height direction of the cup 110, the cavity 111 has a plurality of cross sections, where the cross sections refer to the space enclosed by the inner wall of the cup 110 and a plurality of planes perpendicular to the height direction of the cup 110 respectively form surfaces. The cross section with the largest cross section is defined as a first cross section, that is, the area of the other cross sections is equal to or smaller than the first cross section, and it is understood that the first cross section may be the connection between the upper cup 112 and the bottom plate 113 in fig. 12, or may be on the upper cup 112 or may be on the bottom plate 113, which is not specifically limited herein. When the area of the partially continuous cross-section is equal to the cross-sectional area of the first cross-section, then the portion of the cup 110 is a cylindrical segment and when the area of the partially continuous cross-section gradually decreases upward from the first cross-section, the portion of the cup 110 is a conical segment. It should be noted that, the cross-sectional area of the cavity 111 of the cup assembly 100 in this embodiment gradually decreases from the first cross-sectional area upwards, so that the overall structure of the cup 110 is a cone, or includes at least one section of cone from bottom to top, so that the component force of the slurry upwards can be reduced, the amount of the slurry moving upwards is reduced, and the slurry is ensured to be more accumulated at the lower part of the cup 110, thereby better separating the slag from the slurry in the slurry, and better separating effect. It is understood that the cross section of the cavity 111 may be circular, elliptical, hexagonal or other shapes, which are not specifically limited herein; when the cross section of the cavity 111 is circular, the processing is more convenient, and the rotation is more stable, which is beneficial to reducing the shake of the cup assembly 100 and improving the stability of the cup assembly 100.

In addition, in the cup assembly 100 of the embodiment, the cross-sectional area of the cavity 111 gradually decreases downwards from the first cross-section, which is beneficial to guiding the slurry at the bottom of the cavity 111 upwards in the centrifugal rotation process, so that most of the slurry can flow on the inner wall of the cup 110, and most of the slurry is guided to the inner wall of the cup 110, so that the slurry is easier to adhere to the inner wall of the cup 110, and the separation effect is improved.

Along the height direction of the cup body 110, the cross-sectional area of the inner wall of at least part of the upper cup body 112 gradually decreases along the direction away from the chassis 113, so that at least one section of cone is formed on the upper cup body 112 from bottom to top, thereby being capable of reducing the upward component force of slurry, reducing the amount of slurry moving upwards, ensuring that the slurry is gathered on the chassis 113 more, separating the slag from the slurry, better realizing the separation of the slag and the slurry, and better separating effect. It will be appreciated that the cross-section of the upper cup 112 may be circular, elliptical, hexagonal or other shapes, and is not specifically limited herein.

Referring to fig. 12, it can be understood that the upper cup 112 has a cone structure, so that in the centrifugal separation process of slurry, the upward component force of slurry can be reduced, the amount of slurry moving upwards is reduced, and more slurry is ensured to be gathered on the chassis 113, so that the separation of slag and slurry is realized, and the slurry-slag separation effect is improved. Moreover, the upper cup 112 with the cone structure has smaller processing difficulty and lower processing cost. The upper end of the upper cup 112 is formed with a cup opening 1121, so that the slurry in the cavity 111 can be poured out conveniently, and the cup opening 1121 can be cylindrical, conical or inverted conical, and is not limited herein.

Referring to fig. 12, it can be understood that the inclination angle α of the inner wall of the upper cup 112 is α, which satisfies: 90 DEG alpha is more than or equal to 60 deg. When the inclination angle alpha is larger than 90 degrees, the upper cup body 112 is of a reverse cone structure, slurry in the containing cavity 111 is easy to overflow from the cup opening 1121 under the action of centrifugal force, and after the centrifugal separation of the slurry is finished, the slurry in the slurry is separated downwards in the process of backflow, so that slag adhered to the inner wall of the upper cup body 112 is carried away, and the slurry-slag separation effect is affected; when the inclination angle α is smaller than 60 °, the capacity of the upper cup 112 is smaller, the overall structure of the cup assembly 100 is larger, and the space utilization is lower. Therefore, when the inclination angle α satisfies the above range, the upper cup 112 has a cone structure, so that the upward component force of the slurry can be reduced, the amount of the slurry moving upward can be reduced, the slurry is ensured to be more accumulated on the chassis 113, and the slag is adhered to the inner wall of the upper cup 112, thereby better realizing the separation of the slag and the slurry, and improving the effect of separating the slag.

Referring to fig. 12, in this embodiment, when the rotating shaft 120 rotates in the second direction, i.e. the direction opposite to the first direction, the rotating shaft 120 drives the knife set 130 to rotate relative to the cup 110, so as to grind, the knife set 130 grinds the foodstuff, thereby breaking the cell wall of the cells in the foodstuff, fully releasing vitamins, minerals, phytochemicals, proteins, moisture, etc. in the cells, so as to obtain foodstuff with smaller particle size, and realize cooking processing of the foodstuff. The cutter set 130 may take various forms, such as a stirring cutter or a grinding cutter, where the stirring cutter may be fixedly mounted on the end of the rotating shaft 120 by a screw, and the grinding cutter is sleeved on the side of the rotating shaft 120 near the end.

In addition, when the rotation shaft 120 rotates along the first direction, the cup body assembly 100 achieves centrifugation, the knife set 130 and the cup body 110 synchronously move, so that the foodstuff in the cup body 110 is ensured not to be disturbed, and the separation of the material slag and the slurry is achieved under the action of the centrifugal force. It should be noted that, the manner in which the cup assembly 100 implements cooking may be that the rotating shaft 120 drives the knife set 130 to grind foodstuff in the cavity 111, and after grinding to form slurry, the rotating shaft 120 drives the cup 110 to rotate, and the slurry is centrifuged, so as to implement slurry-residue separation. In addition, in the grinding process, the slurry is driven by the cutter set 130 to form a vortex, the vortex moves upwards along the inner wall of the conical cup 110, and the vortex flows back to the cutter set 130 under the combined action of gravity and the turbulence ribs 1122 to form a vortex in the vertical direction, so that more contact exists between foodstuff and the cutter set 130, and the grinding efficiency is improved.

Therefore, when the rotation shaft 120 rotates in the first direction, the rotation shaft 120 and the cup 110 are interlocked and rotated synchronously, thereby realizing a centrifugal operation; when the rotation shaft 120 rotates in the second direction, the rotation shaft 120 and the cup 110 relatively rotate, and the cup 110 does not rotate along with the cutter set 130, thereby realizing the grinding operation.

Along the direction of keeping away from chassis 113 center, grinding channel 140 reduces gradually in the clearance of upper and lower direction, and the clearance reduces gradually and can make the foodstuff flow to the in-process all around along the center of chassis 113 under the effect of centrifugal force, realizes the course of coarse grinding gradually, semi-fine grinding to fine grinding for the foodstuff fluid progressively carries out the fine grinding, and then realizes the fine grinding of foodstuff, makes the foodstuff grind finer and more exquisite, has further improved the effect of grinding.
