Description

Technical Field

[0001] The present invention relates to small kitchen appliances, in particular to a method for making pulp of a food processor. Background Art

[0002] Currently, food processors on the market, such as soymilk makers with a motor disposed below, generally include a crushing chamber for processing food materials, a motor, a crushing device, and a heating device. A crushing device is disposed in the crushing chamber to perform crushing and cutting on the food materials. The motor is used to drive the crushing device, and the heating device is used to heat the crushing chamber to perform heating and cooking on the food materials. Among them, the motor is located below the crushing chamber, and the motor shaft of the motor axially penetrates into the crushing chamber and is connected to the crushing device. The top open end of the crushing chamber is hermetically covered with a cup lid, that is, the side wall of the cup lid is hermetically fitted with the inner side wall of the crushing chamber. Usually, a through ventilation hole is provided in the central area of the cup lid so that the hot air generated during food material processing can be transmitted to the outside through the ventilation hole to avoid the top cover. Generally, the radius of the central area is not greater than half of the radius of the cup lid.

[0003] However, for a soymilk maker not equipped with an anti-overflow electrode, only setting the ventilation hole still has the problem of easy pulp overflow when making hot drinks. For measures to solve the pulp overflow problem, there are mainly the following several solutions in the prior art:

[0004] Solution 1: Avoid pulp overflow by reducing the temperature of the slurry during pulp making. However, this solution will have problems such as insufficient cooking of food materials (such as beans), and the nutrients and flavors of the food materials themselves cannot be released, and the production cycle also needs to be extended.

[0005] Solution 2: During the pulp making process, beating and heating are alternately performed at intervals. However, this solution will also lead to an extended overall production cycle and reduce the user experience.

[0006] Solution 3: As in the patent with the application number 202011566295.0, by dividing the crushing and boiling stage into at least two crushing sub-stages, implementing crushing and boiling cycle control in each of the crushing sub-stages, and setting a second waiting duration Δt2 between the two crushing sub-stages; the crushing and boiling cycle control includes multiple sub-cycles. In each sub-cycle, when continuous crushing is performed, the heating device is used for intermittent heating, and when continuous heating is performed, the motor is used for intermittent slurry stirring. Since this solution performs intermittent heating under continuous crushing, it saves the pulping cycle compared to Solution 1 and Solution 2, and can also achieve the purpose of reducing the risk of overflowing slurry. However, on the one hand, this solution requires setting two crushing sub-stages, and multiple sub-cycles are set in each crushing sub-stage, which requires two cycle control modules to implement, and the program control is relatively complex; on the other hand, this solution only considers that intermittent slurry stirring is performed in each sub-cycle of the crushing sub-stage by heating for a period of time, driving the motor to stir for a period of time and then pausing for a period of time during the heating process. In this way, there is still a risk that when the user accidentally adds an excessive amount of mixture (such as water + beans), then after the mixture entering the crushing and boiling stage becomes slurry, if the slurry is not whipped up at this time, then even with intermittent heating, there is still a risk of boiling and foaming rising to the vent holes of the cup lid and causing overflow.

[0007] In summary, none of the existing solutions have considered how to further optimize the pulping process without increasing the pulping cycle for an under-mounted food processor to solve the risk problem of foam overflowing from the vent holes in the central area of the cup lid, especially the risk of slurry overflow when the user accidentally adds an excessive amount of mixture (such as water + beans). Summary of the Invention

[0008] The object to be achieved by the present invention is to provide a pulping method for a food processor. For an under-mounted food processor, how to further optimize the pulping process without increasing the pulping cycle to solve the risk problem of foam overflowing from the vent holes in the central area of the cup lid, especially the risk of slurry overflow when the user accidentally adds an excessive amount of mixture (such as water + beans).

[0009] To achieve the above object, the present invention adopts the following technical solution: A pulping method for a food processor, the food processor includes a crushing chamber, a motor, and a cup lid hermetically covered at the open end of the crushing chamber. A through vent hole is provided in the central area of the cup lid. The pulping method includes:

[0010] During the pulping process of the food processor, it is judged whether the temperature of the slurry in the crushing chamber reaches a first preset temperature at the boiling state;

[0011] When the slurry temperature in the crushing chamber is lower than the first preset temperature, it is judged whether the slurry temperature in the crushing chamber reaches the second preset temperature, where the first preset temperature is higher than the second preset temperature.

[0012] When the slurry temperature in the crushing chamber is lower than the second preset temperature, perform a whipping process on the slurry to form a V-shaped liquid surface with a lower middle and a higher periphery, and perform a first heating process after forming the V-shaped liquid surface. During the first heating process, it is necessary to maintain the slurry temperature lower than the second preset temperature, and stop the first heating process before the whipping process stops.

[0013] Furthermore, the height difference between the static liquid surface of the slurry and the inner bottom surface of the crushing chamber is H1, and the height difference of the slurry forming the V-shaped liquid surface is H2, where 1.2 ≤ H2 / H1 ≤ 5.1, and the lowest point of the V-shaped liquid surface is higher than the crushing device in the crushing chamber.

[0014] Furthermore, the pulping process includes multiple whipping processes. When the single whipping duration is greater than the first preset duration, it is determined whether to perform the first heating process according to the current motor whipping speed; when the single whipping duration is not greater than the first preset duration, the first heating process is not performed.

[0015] Furthermore, the determining whether to perform the first heating process according to the current motor whipping speed includes:

[0016] When the current motor whipping speed is not less than the motor preset speed, perform the first heating process;

[0017] When the current motor whipping speed is less than the motor preset speed, do not perform the first heating process.

[0018] Furthermore, the first heating process includes adjusting the heating power P of the first heating process according to the rated heating power P0. Where when P0 ≤ 1000w, adjust P = P0; when P0 > 1000w, adjust P = 1 / 2P0;

[0019] Alternatively, the pulping process includes multiple whipping stages. In a single whipping stage, the interval duration from the start of the motor to the start of the first heating process is △t1, and the interval duration from the stop of the first heating process to the stop of the motor rotation is △t2, where 3 / 5 ≤ △t1 / △t2 ≤ 10 / 3.

[0020] Furthermore, the pulping method further includes: when the slurry temperature in the crushing chamber is between the first preset temperature and the second preset temperature, perform a second heating process and adjust the heating power P to be lower than the rated heating power P0.

[0021] Further, the adjustment of the heating power P being less than the rated heating power P0 includes: the first preset temperature is T1, the slurry temperature is T, and T1, T, P, and P0 satisfy that when T1 - 5 ≤ T < T1 and P0 ≤ 1000w, P = 1 / 3 * P0; when T1 - 10 ≤ T < T1 - 5, P = 1 / 2 * P0; when T1 - 5 ≤ T < T1 and P0 > 1000w, P = 1 / 4 * P0; when T1 - 10 ≤ T < T1 - 5, P = 1 / 3 * P0.

[0022] Further, the first heating treatment is an intermittent heating treatment, including: a continuous heating stage and a stop heating stage, which are cyclically and alternately executed. The duration of a single continuous heating stage is t1, the duration of a single stop heating stage is t2, the first preset temperature is T1, and the slurry temperature is T. t1 and t2 are determined according to the ratio of T1 to T.

[0023] Further, determining t1 and t2 according to the ratio of T1 to T includes: the pulping process includes multiple beatings. In a single beating, the second preset duration is t1', and the third preset duration is t2'. Among them, when t1 remains unchanged, t2 is determined according to the product of t2' and T / T1, t2 = t2' * (T / T1); when t2 remains unchanged, t1 is determined according to the product of t1' and T1 / T, t1 = t1' * (T1 / T).

[0024] Further, the first preset temperature is T1 and the second preset temperature is T2, where T1 and T2 satisfy: T2 = T1 - 3°C;

[0025] Or, the first preset temperature is T1, and 92°C ≤ T1 ≤ 100°C;

[0026] Or, a crushing device is provided in the crushing chamber, and the rotation speed of the crushing device is n, where n ≥ 6000r / min;

[0027] Or, the ventilation holes are provided at the center of the cup lid;

[0028] Or, the central area of the cup lid is provided with through ventilation holes, and the ratio of the area of the central area to the top surface area of the cup lid is between 0.1 and 0.5;

[0029] Or, the height difference between the lowest point of the V-shaped liquid surface and the static liquid surface of the slurry is H3, where H3 satisfies: 20mm ≤ H3 ≤ 55mm.

[0030] The present invention also has the following beneficial effects:

[0031] 1. For a food processor, especially a bottom-mounted food processor with heating function, such as a bottom-mounted soybean milk maker, since the anti-overflow electrode is removed, during the pulping process, a large amount of foam on the surface of the slurry is likely to rise to the ventilation holes in the central area of the cup lid and overflow from the ventilation holes.

[0032] As we know, during the pulping process, when the temperature of the slurry reaches the first preset temperature at the boiling state, the generated foam is the most and the strongest. Therefore, in the present invention, first, during the pulping process, it is judged whether the temperature of the slurry in the crushing cavity reaches the first preset temperature. If it reaches the first preset temperature, it is not suitable to perform the first heating treatment any more, so as to prevent the foam from continuing or further generating and causing a more serious overflow problem. If the temperature of the slurry in the crushing cavity is lower than the first preset temperature, it is further judged whether the temperature of the slurry in the crushing cavity reaches the second preset temperature at the overflow state.

[0033] When the temperature of the slurry in the crushing cavity is less than the second preset temperature, it can effectively ensure that the slurry will not overflow at this time. Therefore, the first heating treatment is added during the process to ensure good ripening of the material without prolonging the pulping cycle. More importantly, the slurry is whipped to form a V-shaped liquid surface with a lower middle and a higher periphery, and the first heating treatment is performed after the V-shaped liquid surface is formed. In this way, the lower part of the slurry surface just faces the ventilation holes of the cup lid, and the distance between the top surface of the ventilation holes and the V-shaped liquid surface is much greater than the distance between the slurry surface and the ventilation holes when the slurry is in a static state. Due to the sealed cooperation between the cup lid and the inner side wall of the crushing cavity, even if the slurry touches the joint between the inner wall of the crushing cavity and the cup lid, it will not overflow from the lid. The foam generated during the first heating treatment of the slurry is difficult to overflow to the outside of the cup lid through the ventilation holes, achieving a good anti-overflow effect. At the same time, in order to further prevent too much foam from overflowing from the ventilation holes during the first heating treatment, it is also set that the temperature of the slurry needs to be maintained less than the second preset temperature during the first heating treatment. During the process of the motor slowly stopping, the slurry surface will gradually tend to the liquid surface state when the slurry is static, that is, the distance between the top surface of the ventilation holes and the V-shaped liquid surface will gradually decrease. Then, if the first heating treatment is still performed after the motor stops rotating, it may cause the foam to overflow from the ventilation holes. Therefore, in order to further reduce the influence of the first heating treatment on slurry overflow, in the present invention, the first heating treatment is also set to stop before the whipping treatment stops, so as to stop the first heating treatment before the slurry surface returns to the static state, thereby avoiding slurry overflow. In addition, during the pulping process of this solution, the crushing device rotates while the first heating treatment is carried out. Compared with the existing solutions where heating and crushing are performed alternately or the heating temperature is reduced, the pulping cycle is effectively shortened, improving the user experience.

[0034] 2. When the crushing device rotates and the slurry only ripples slightly, the height difference between the top surface of the slurry and the top surface of the ventilation holes is not much different from the height difference between the liquid level of the stationary slurry and the top surface of the ventilation holes. At this time, if the heating treatment is carried out, the risk of slurry overflow at the ventilation holes is still very high. Therefore, in the present invention, the height difference H1 between the stationary liquid level of the slurry and the inner bottom surface of the crushing chamber is set to form the height difference H2 of the slurry in the V-shaped liquid level, and the lower limit of H2 / H1 is 1.2. Only when the slurry forms a more obvious ripple under the drive of the crushing device is it considered that a V-shaped liquid level is formed, thereby reducing the risk of slurry overflow after the heating treatment is carried out when the V-shaped liquid level is formed. Generally, the volume of the slurry remains unchanged whether the slurry ripples or not. Thus, when the slurry ripples to the edge of the V-shaped liquid level close to the central area, the height difference of the slurry forming the V-shaped liquid level is the largest. Generally, the diameter of the central area is half of the diameter of the cup lid or less. That is, the radius of the central area is also approximately equal to half of the inner diameter of the crushing chamber (defined as r). Thus, the volume of the slurry when it is stationary is set as V 静 , the height difference is H1, V 静 =Πr 2 H1. The volume of the slurry when the maximum height difference of the slurry forming the V-shaped liquid level is set as V max , the height difference is H2, the radius of the central area is 1 / 2r, and the lowest surface of the V-shaped liquid level is on the inner bottom surface of the crushing chamber. In the existing food processors, the height difference between the top surface of the crushing device and the inner bottom surface of the crushing chamber is about 0.15 to 0.2 times the height of the crushing chamber. In the present invention, the maximum height difference H2 of the slurry in the V-shaped liquid level is set to be approximately equal to the height of the crushing chamber. That is, at this time, the height difference between the top surface of the crushing device and the inner bottom surface of the crushing chamber can be defined as about 0.15H2 - 0.20H2. Therefore, V max =1 / 3Π(1 / 2r) 2 H2, 2V max =V 静 , from which H2 / H1 = 6 is calculated. However, in order to prevent the phenomenon of dry running when the V-shaped liquid level is lower than the crushing device, it is also necessary to set that the maximum height difference of the slurry in the actual V-shaped liquid level should be 0.80H2 - 0.85H2, that is, preferably H2 / H1 = 0.80 * 6 - 0.85 * 6 = 4.8 - 5.1. From this measurement, in the present invention, the upper limit value of H2 / H1 should be 5.1. Only within this range can the slurry form a V-shaped liquid level and the dry running of the slurry can be avoided.

[0035] 3. In order to ensure that there is a sufficient distance between the ventilation holes of the cup lid and the slurry liquid level, especially during the first heat treatment process, it is beneficial to avoid slurry overflow and prevent the phenomenon of dry beating during the whipping process, which delays the pulp making cycle. In the present invention, the height difference H3 between the lowest point of the V-shaped liquid level and the static slurry liquid level satisfies 20 mm ≤ H3 ≤ 55 mm. When H3 < 20 mm, the formed V-shaped liquid level is not steep enough, and the distance between the slurry liquid level and the top surface of the ventilation hole is not much different from the distance between the static slurry liquid level and the top surface of the ventilation hole, so there is still a risk of overflow. When H3 > 55 mm, the formed V-shaped liquid level is too steep, and the lowest point of the V-shaped liquid level will be lower than the pulverizing device, resulting in dry beating of the pulverizing device.

[0036] 4. If the second heat treatment is not performed once the second preset temperature is reached, it is necessary to wait until the temperature of the slurry in the pulverizing chamber drops below the second preset temperature before performing the second heat treatment, which will prolong the overall pulp making cycle. Therefore, in order to shorten the overall pulp making cycle, in the present invention, when the temperature of the slurry in the pulverizing chamber is between the first preset temperature and the second preset temperature, the pulverizing device in the pulverizing chamber is controlled to rotate to form a V-shaped liquid level, and the second heat treatment is still performed. And it is necessary to adjust the heating power P during the second heat treatment to be lower than the rated heating power P0 to maintain that the foam generated on the surface of the slurry is always small and does not touch the ventilation holes. In this way, it can slightly increase the temperature for material ripening, accelerate material ripening, and avoid slurry overflow at the ventilation holes and shorten the pulp making cycle as much as possible.

[0037] 5. In the present invention, it is also set that the pulp making process includes multiple whippings to avoid serious heating of the motor caused by long-term continuous pulverization of the motor, which affects the service life of the motor. On this basis, during a single whipping, when it is determined that the duration of a single whipping is greater than the first preset duration, whether to perform the first heat treatment is determined according to the whipping speed of the motor, which can reasonably avoid the problem of slurry overflow caused by performing the first heat treatment when the actual duration of a single whipping is very short and the whipping duration is not enough to form a V-shaped liquid level in the pulverizing chamber. Moreover, even if the actual duration of a single whipping reaches the preset duration, it is necessary to further determine whether the whipping speed of the motor is greater than the preset speed of the motor to better determine that the current whipping speed of the motor can form a V-shaped liquid level during this whipping duration and maintain the V-shaped liquid level for a period of time before performing the first heat treatment to ensure a good anti-overflow effect.

[0038] 6. To further avoid generating excessive foam during the first heating process, issues such as overflow and the problem that excessive foam affects the taste of the slurry. The present invention also sets the heating power P of the first heating process to be adjusted according to the rated heating power P0 during the first heating process. Among them, when P0 ≤ 1000w, adjust P = P0; when P0 > 1000w, adjust P = 1 / 2P0. When the slurry temperature is lower than the second preset temperature and the rated power P0 is relatively small, since the foam generated at the current low temperature is less, the heating power P can be increased, and adjust P = P0, that is, when P0 ≤ 1000w, P = P0; when the slurry temperature is lower than the second preset temperature and the rated power P0 is relatively large, since the foam generated at the current relatively high temperature is relatively more, the heating power P needs to be reduced, and the heating power P is set to half of the rated power P0, that is, when P0 > 1000w, P = 1 / 2P0.

[0039] To avoid the problem that the time for the slurry to form a V-shaped liquid level is too long, which prolongs the pulping cycle, and / or to avoid the problem that after the heating process stops, the motor stops too quickly, resulting in the residual temperature of the slurry causing the foam not to have time to disappear, that is, the problem that the foam is still at a relatively high position or even overflows from the overflow vent. The interval duration from when the motor starts to when the first heating process starts is △t1, and the interval duration from when the first heating process stops to when the motor stops rotating is △t2, and 3 / 5 ≤ △t1 / △t2 ≤ 10 / 3.

[0040] 7. In the present invention, to avoid the problem that during the first heating process, when continuously heating, the foam gradually increases, infinitely approaches the vent hole or even overflows from the vent hole, an intermittent heating process for the heating process is set, and it includes: a continuous heating stage and a stop heating stage, and the continuous heating stage and the stop heating stage are executed in a cyclic and alternating manner. The rotation of the pulverizing device continues to be executed during the intermittent heating process. At the same time, in addition to preventing overflow, it is also necessary to improve the efficiency of material ripening. Therefore, by setting the duration of a single continuous heating stage to be t1, the duration of a single stop heating stage to be t2, the first preset temperature to be T1, and the slurry temperature to be T, t1 and t2 are determined according to the ratio of T1 and T. Specifically, the pulping process includes multiple whipping stages. In a single whipping stage, the second preset duration is t1', and the third preset duration is t2'. Among them, when t1 remains unchanged, t2 is determined according to the product of t2' and T / T1, t2 = t2'*(T / T1); when t2 remains unchanged, t1 is determined according to the product of t1' and T1 / T, t1 = t1'*(T1 / T). That is to say, the present invention forms a steady-state first heating process by adjusting t1 and t2, which can not only efficiently ripen the material to meet the conditions for drinking the beverage, but also prevent overflow.

[0041] Other features and advantages of the present invention will be described in detail in the subsequent specific implementation section. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The following will give a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not used to limit the present invention.

[0049] Embodiment 1:

[0050] As Figure 1 and 2 shown, it is a schematic diagram of the structure of the food processor in the present invention. The following takes a bottom-mounted soybean milk machine as an example for description. The food processor described in the present invention includes a main body 1 provided with a motor 11, a crushing chamber formed by the inner cavity of a crushing cup 2 disposed above the main body 1, a crushing device 21 disposed in the crushing chamber, and a cup cover 3 is further covered at the open top of the crushing chamber. The cup cover 3 is sealingly connected to the open top of the crushing chamber. The cup cover 3 includes a cover base 31 that is cooperatively connected to the upper edge of the crushing cup. A vent plug 32 is provided in the central area of the cover base 31, and a through vent hole 321 is provided on the vent plug 32. In this solution, the crushing device 21 is a crushing knife, and the output shaft of the motor 11 extends into the crushing chamber and is connected to the crushing knife to drive the crushing knife to rotate and crush the food materials. A heating device 4 is provided at the bottom of the crushing chamber to heat and cook the food materials in the crushing chamber. For a food processor, especially a bottom-mounted food processor with heating, such as a bottom-mounted soybean milk machine, since the anti-overflow electrode is cancelled, during the pulp-making process, more foam is generated on the surface of the slurry and is likely to rise to the vent hole 321 of the cup cover 3 and overflow from the vent hole 321. Especially when the user accidentally adds an excessive amount of mixture (such as water + beans), the risk of slurry overflow is more serious.

[0051] It should be noted that the cup lid 3 may not have a ventilation plug 32, and the ventilation hole 321 is directly integrally formed on the lid base body 31. Regarding the installation position of the heating device 4, it is not limited to the limitation of this embodiment. For example, it can be installed at the bottom of the crushing chamber or on the side of the crushing chamber. For the crushing device 21, in addition to the crushing knife, other accessories can also be replaced according to requirements, such as a dough mixing knife.

[0052] In the present invention, during the cleaning process, a process of hot and cold flushing is set. By utilizing the instantaneous stress generated by the hot and cold impact, the residue undergoes a certain morphological change, which can effectively prompt the residue to fall off from the cup wall. Additionally, in the case of hot and cold flushing, the residue may also be decomposed and broken to a certain extent, which is beneficial for the discharge of the residue and can avoid the problem of the residue blocking the slurry discharge valve during the waste discharge process.

[0053] Specifically, in a specific embodiment of the present invention, referring to Figure 3 , the pulping method at least includes the following steps:

[0054] Step S100: During the pulping process of the food processor, determine whether the temperature of the slurry in the crushing chamber reaches the first preset temperature at the boiling state;

[0055] Step S200: When the temperature of the slurry in the crushing chamber is lower than the first preset temperature, determine whether the temperature of the slurry in the crushing chamber reaches the second preset temperature, where the first preset temperature is higher than the second preset temperature;

[0056] Step S300: When the temperature of the slurry in the crushing chamber is lower than the second preset temperature, perform a whipping process on the slurry to form a V-shaped liquid surface with a lower middle and a higher periphery, and perform a first heating process after forming the V-shaped liquid surface. During the first heating process, it is necessary to maintain the temperature of the slurry lower than the second preset temperature, and stop the first heating process before the whipping process stops.

[0057] Generally speaking, during the pulping process, if the temperature of the slurry reaches the first preset temperature at the boiling state, more and stronger foam is generated compared to when it is lower than the first preset temperature. The boiling state includes the cases of local boiling, near-full boiling, or full boiling of the slurry. Therefore, in step S100, it is necessary to first determine whether the temperature of the slurry in the crushing chamber reaches the first preset temperature at the boiling state during the pulping process. If it reaches the first preset temperature, it is not suitable to further increase the first heating process to prevent the continuous generation or further generation of foam and avoid a more serious overflow problem. If the temperature of the slurry in the crushing chamber is less than the first preset temperature, it is still necessary to further determine whether the temperature of the slurry in the crushing chamber reaches the second preset temperature.

[0058] In addition to the first preset temperature, the second preset temperature is the one most prone to overflow risk. The second preset temperature refers to the temperature when the slurry is about to overflow or has already overflowed. Therefore, when it is detected that the temperature of the slurry has not reached the first preset temperature at the boiling state, it is necessary to further determine whether the temperature of the slurry is less than the second preset temperature to determine whether it can effectively ensure that the slurry will not overflow at this time. Then, it is further determined whether to perform the first heating treatment. In the present invention, the second preset temperature is T2, and 85°C ≤ T2 ≤ 95°C. Preferably, the corresponding second preset temperature is preferentially selected according to the current altitude. For example, in the usual low-altitude area, T2 can be selected as 90°C.

[0059] In a preferred embodiment, the first preset temperature is T1, and 92°C ≤ T1 ≤ 100°C. Thus, the first preset temperature at the boiling state corresponding to the altitude can be adaptively adjusted according to the different altitudes.

[0060] In another preferred embodiment, the first preset temperature is T1 and the second preset temperature is T2, where T1 and T2 satisfy: T2 = T1 - 3°C. Thus, the refinement between the first preset temperature and the second preset temperature can be considered, that is, the gap between the two is as small as possible to ensure good boiling effect and prevent overflow.

[0061] It should be noted that the first preset temperature and the second preset temperature are not uniquely determined values, but a range of temperature values. The specific preset temperature value needs to be determined according to the current altitude. For example, in the case of high altitude, the first preset temperature may only need to be 98°C, and when at ordinary altitude, the first preset temperature may be 100°C.

[0062] When the temperature of the slurry in the crushing chamber is less than the second preset temperature, it can effectively ensure that the slurry will not overflow at this time. Therefore, in step 300 of the present invention, when it is determined that the temperature of the slurry in the crushing chamber is less than the second preset temperature, heating treatment is added during the pulping process to ensure good ripening of the material without prolonging the pulping cycle.

[0063] More importantly, in step 300, it is also necessary to control the rotation of the pulverizing device 21 in the pulverizing chamber to agitate the slurry until a V-shaped liquid surface with a lower middle and a higher periphery is formed, and perform a first heating treatment after the V-shaped liquid surface is formed. In this way, the lowest or lower part of the slurry surface is exactly opposite to the air vent 321 of the cup lid 3, increasing the distance between the slurry surface and the top surface of the air vent 321, and the distance between the lowest or lower part of the slurry surface and the air vent 321 is much greater than the distance between the slurry surface and the air vent 321 when the slurry is in a static state. The foam generated by the slurry during the first heating treatment is difficult to overflow through the air vent 321 to the outside of the cup lid 3, achieving a good anti-overflow effect. At the same time, in order to further prevent too much foam from overflowing through the air vent 321 during the first heating treatment, it is also set that the temperature of the slurry needs to be maintained below the second preset temperature during the first heating treatment.

[0064] Generally, during the process of the motor 11 slowly stopping, the slurry surface will gradually tend to the liquid surface state when the slurry is stationary, that is, the distance between the lowest part of the slurry and the air vent 321 will gradually decrease. Then, if the first heating treatment is still performed after the motor 11 stops rotating, which is equivalent to performing the first heating treatment after the agitation treatment stops, it may cause the foam to overflow from the air vent 321. Therefore, in order to further reduce the influence of the first heating treatment on slurry overflow, in the present invention, the first heating treatment is stopped before the motor 11 stops rotating, so as to stop the first heating treatment before the slurry surface returns to the stationary state, thereby avoiding slurry overflow. In addition, during the pulp making process of this solution, the pulverizing device 21 rotates while the first heating treatment is carried out. Compared with the existing solutions where heating and pulverizing are performed alternately or the heating temperature is reduced, the pulp making cycle is effectively shortened, improving the user experience.

[0065] In a preferred embodiment, in order to avoid the slurry from being idly beaten and to perform the heating treatment only after the V-shaped liquid surface of the slurry is formed to avoid overflow at the air vent 321, the height difference between the stationary liquid surface of the slurry and the inner bottom surface of the pulverizing chamber is set as H1, and the height difference of the slurry forming the V-shaped liquid surface is set as H2, where 1.2 ≤ H2 / H1 ≤ 5.1, and the lowest point of the V-shaped liquid surface is higher than the pulverizing device 21 in the pulverizing chamber.

[0066] Specifically analyzed, when the crushing device 21 rotates and the slurry only ripples slightly, the height difference between the top surface of the slurry and the top surface of the air vent 321 is not much different from the height difference between the liquid level of the stationary slurry and the top surface of the air vent 321. At this time, if the heating treatment is carried out, the risk of slurry overflow at the air vent 321 is still very high. Therefore, in the present invention, the height difference H1 between the stationary liquid level of the slurry and the inner bottom surface of the crushing chamber is set, and the height difference H2 of the slurry forming a V-shaped liquid level is formed. The lower limit of H2 / H1 is 1.2. It is only when the slurry forms a more obvious ripple under the drive of the crushing device 21 that it is determined that a V-shaped liquid level is formed, thereby reducing the risk of slurry overflow after the heating treatment is carried out after the V-shaped liquid level is formed. Generally, the volume of the slurry remains unchanged regardless of whether the slurry ripples or not. Thus, when the slurry ripples to the edge of the V-shaped liquid level close to the central region, the height difference of the slurry forming the V-shaped liquid level is the largest. Generally, the diameter of the central region is half of the diameter of the cup lid 3 or less. That is, the radius of the central region is also approximately equal to half of the inner diameter of the crushing chamber (defined as r). Thus, the volume of the slurry when it is stationary is set as V 静 , the height difference is H1, V 静 =Πr 2 H1. The volume of the slurry when the maximum height difference of the slurry forming a V-shaped liquid level is set as V max , the height difference is H2, the radius of the central region is 1 / 2r, and the lowest surface of the V-shaped liquid level is on the inner bottom surface of the crushing chamber. In the existing food processor, the height difference between the top surface of the crushing device 21 and the inner bottom surface of the crushing chamber is about 0.15 to 0.2 times the height of the crushing chamber. In the present invention, the maximum height difference H2 of the slurry of the V-shaped liquid level is set to be approximately equal to the height of the crushing chamber. That is, at this time, the height difference between the top surface of the crushing device 21 and the inner bottom surface of the crushing chamber can be defined as about 0.15H2~0.20H2. Therefore, V max =1 / 3Π(1 / 2r) 2 H2, 2V max =V 静 , from which H2 / H1 = 6 is calculated. However, in order to prevent the phenomenon of dry running when the V-shaped liquid level is lower than the crushing device 21, it is also necessary to set that the maximum height difference of the slurry of the actual V-shaped liquid level should be 0.80H2~0.85H2, that is, preferably H2 / H1 = 0.80*6~0.85*6 = 4.8~5.1. From this calculation, in the present invention, the upper limit value of H2 / H1 should be 5.1. Only within this range can the slurry form a V-shaped liquid level and avoid dry running of the slurry.

[0067] In a preferred embodiment, in order to ensure that there is a sufficient distance between the ventilation holes 321 of the cup lid 3 and the slurry liquid level, especially during the first heat treatment process, it is beneficial to avoid slurry overflow and prevent the phenomenon of dry beating during the whipping process, thereby delaying the pulp making cycle. In the present invention, the height difference H3 between the lowest point of the V-shaped liquid level and the static slurry liquid level is set, and H3 satisfies 20 mm ≤ H3 ≤ 55 mm. When H3 < 20 mm, the formed V-shaped liquid level is not steep enough, and the distance between the slurry liquid level and the top surface of the ventilation holes 321 is not much different from the distance between the static slurry liquid level and the top surface of the ventilation holes 321, so there is still a risk of overflow. When H3 > 55 mm, the formed V-shaped liquid level is too steep, and the lowest point of the V-shaped liquid level may be lower than the crushing device 21, resulting in dry beating of the crushing device 21.

[0068] Generally, the vertical distance between the top surface of the ventilation holes 321 and the slurry surface is H3, and when the slurry is in a static state, the distance between the slurry surface and the ventilation holes 321 is h2. Preferably, H3 / h2 > 1.3.

[0069] It should be noted that the formed V-shaped liquid level of the slurry means that the ratio of the height difference between the highest point and the lowest point of the V-shaped liquid level to the height difference between the cup mouth and the lowest point of the V-shaped liquid level is more than 1 / 2. In another preferred embodiment, the formed V-shaped liquid level of the slurry means that the rotational speed of the crushing device 21 reaches the maximum rotational speed.

[0070] It should also be noted that in the present invention, the rotational speed of the crushing device 21 is set to n, where n ≥ 6000 r / min, so that when the motor 11 starts and reaches the highest and constant rotational speed n ≥ 6000 r / min, the slurry can form a relatively high V-shaped liquid level.

[0071] In the present invention, the second preset temperature is set to T2, 85°C ≤ T2 ≤ 95°C, to ensure that at high altitudes, when the slurry reaches the preset T2, there will be no obvious and excessive foam, resulting in the foam overflowing from the ventilation holes 321. Preferably, T2 can be 86°C, 88°C, 90°C, 92°C, 94°C.

[0072] In the present invention, as Figure 2As shown, in a preferred embodiment, a ventilation plug 32 is provided in the central region of the cover base body 31, and a through ventilation hole 321 is provided on the ventilation plug 32; alternatively, the ventilation hole 321 is directly integrally formed in the central region of the cover base body 31. It should be noted that the central region refers to the region range formed by the outer circle of the ventilation plug 32. The radius of the outer edge of the cover region is R1, and the ventilation plug 32 is coaxially arranged with the cover base body 31 of the cup cover 3, that is, the central region is coaxially arranged with the cup cover 3. Moreover, the ventilation hole 321 is offset relative to the central axis of the ventilation plug 32, and the radius of the outer edge of the ventilation plug 32 relative to the central axis of the ventilation plug 32 is R3.

[0073] In another embodiment, the ventilation hole can also be directly provided in the center of the cup cover, that is, if there is a ventilation plug, it is provided in the center of the ventilation plug, and if not, it is directly provided in the center of the cover base body.

[0074] It can be understood that if the ventilation plug 32 and the cover base body 31 are integrally formed, that is, the ventilation hole 321 is directly formed on the cover base body 31, then the central region of the present invention refers to the region formed by radially extending outward along the central axis of the cover base body 31. This central region is preferably circular, but can also be other shapes, without specific limitation. The area of this central region is S1, the radius of the cover base body 31 is R2, and the area of the cover base body 31 is S2, where 0.1 ≤ S1 / S2 ≤ 0.5, that is, the ratio of the area of the central region to the top surface area of the cup cover 3 is between 0.1 and 0.5. This is because if the area of the central region is too large, then when the ventilation hole 321 is provided at the edge of the central region and the slurry forms a V-shaped liquid surface, the distance between the ventilation hole 321 and the swirling liquid surface is very small, and overflow of the slurry may occur if the first heating treatment is performed. Additionally, if the area of the central region is too small, it may be difficult to provide the ventilation hole 321 in this central region, or the aperture of the ventilation hole 321 is not large enough, resulting in the situation of the top cover. For the position of the ventilation hole 321 in the central region, the present invention does not make specific limitations.

[0075] Furthermore, in order to prevent the motor 11 from overheating severely due to continuous pulverization for a long time, which affects the service life of the motor 11, it is also provided that the pulping process further includes multiple beatings. During a single beating, it is judged whether the preset beating duration is less than the actual beating duration;

[0076] When it is judged that the single-beating duration is greater than the first preset duration, it is determined whether to perform the first heating treatment according to the current beating speed of the motor 11.

[0077] It should be noted that the first preset duration is not the preset duration for the food processor to perform a single beating, but a judgment value used to compare with the single-beating duration to determine whether to "determine whether to perform the first heating treatment according to the current beating speed of the motor 11".

[0078] Under this solution, during a single stirring, when it is determined that the duration of a single stirring is greater than the first preset duration, it is determined whether to perform the first heating treatment according to the current stirring speed of the motor 11; when the duration of a single stirring is not greater than the first preset duration, the first heating treatment is not performed. In this way, the problem of overflowing slurry can be reasonably avoided, specifically to avoid the problem of slurry overflow during the first heating treatment when the actual duration of a single stirring is very short and this stirring duration is not sufficient to form a V-shaped liquid level in the crushing chamber. Moreover, even if the actual duration of a single stirring reaches the first preset duration, it is still necessary to further determine whether the stirring speed of the motor 11 reaches the preset speed of the motor 11, so as to better determine that the current stirring speed of the motor 11 can form a V-shaped liquid level within this stirring duration and can maintain the V-shaped liquid level for a period of time before performing the heating treatment to ensure a good anti-overflow effect.

[0079] Specifically, determining whether to perform the first heating treatment according to the current stirring speed of the motor 11 includes: when the current stirring speed of the motor 11 is not less than the preset speed of the motor 11, the heating device 4 performs the first heating treatment. That is to say, when the current stirring speed of the motor is not less than the preset speed of the motor, it is considered that a V-shaped liquid level has been formed in the slurry and the subsequent V-shaped liquid level can be maintained. On the contrary, when the current stirring speed of the motor is less than the preset speed of the motor, the first heating treatment is not performed.

[0080] Furthermore, in order to further avoid generating more foam during the first heating treatment, resulting in overflow problems and the problem that the multi-foam affects the taste of the slurry. In this embodiment, it is also set that the first heating treatment includes: adjusting the heating power P of the first heating treatment according to the rated heating power P0, the rated heating power is P0, and P and P0 satisfy: when P0 ≤ 1000w, adjust P = P0; when P0 > 1000w, adjust P = 1 / 2P0. In this way, when the slurry temperature is lower than the second preset temperature and the rated heating power is small, since the foam generated at the current low temperature is less, the heating power can be increased and adjusted to P = P0; when the slurry temperature is lower than the second preset temperature and the rated heating power is large, since the foam generated at the current relatively high temperature is relatively more, the heating power needs to be reduced and adjusted to P = 1 / 2P0.

[0081] Specifically, in order to avoid the problem that during the first heating process, when heating is continuously performed at the heating power P, the foam gradually increases, approaches the air vent 321 infinitely, or even overflows from the air vent 321. In this embodiment, the first heating process is set as an intermittent heating process, including: a continuous heating stage and a heating stop stage, the continuous heating stage and the heating stop stage are executed in a cyclic and alternating manner, the duration of a single continuous heating stage is t1, the duration of a single heating stop stage is t2, the first preset temperature is T1, the slurry temperature is T, and t1 and t2 are determined according to the ratio of T1 and T.

[0082] Meanwhile, in addition to preventing overflow, it is also necessary to improve the efficiency of material ripening. Therefore, by fixing one of t1 and t2 and adaptively adjusting the other one of t1 and t2 according to the ratio of the slurry temperature T and the first preset temperature T1. That is to say, by coordinating t1 and t2, a steady-state heating process is formed, which can not only efficiently ripen the material to meet the conditions for drinking the beverage, but also prevent overflow and improve the user experience.

[0083] Further, the pulping process includes multiple beatings. In a single beating, the second preset duration is t1', and the third preset duration is t2'. It should be noted that the second preset duration is not the preset duration for the food processor to perform a single continuous heating, but a preset judgment value, which is used for comparison and calculation with the actual duration t1 of a single continuous heating stage. For example, when t2 remains unchanged, the t1 value is calculated according to T1 / T; the third preset duration is not the preset duration for the food processor to perform a single heating stop, but a preset judgment value, which is used for comparison and calculation with the actual duration t2 of a single heating stop stage. For example, when t1 remains unchanged, the t2 value is calculated according to T / T1.

[0084] In one implementation manner, when t1 remains unchanged, t2 is determined according to the product of t2' and T / T1, t2 = t2'*(T / T1);

[0085] In another implementation manner, when t2 remains unchanged, t1 is determined according to the product of t1' and T1 / T, t1 = t1'*(T1 / T).

[0086] Embodiment 2

[0087] The difference between this embodiment and Embodiment 1 is that when it is judged in step S100 that the slurry temperature in the crushing cavity is lower than the first preset temperature, and then when it is judged in step S200 that the slurry temperature in the crushing cavity reaches the second preset temperature, the second heating process is executed.

[0088] If the heating process is not performed once the second preset temperature is reached, it is necessary to wait for the temperature of the slurry in the crushing chamber to drop below the second preset temperature before performing the first heating process, which will prolong the overall pulping cycle. Specifically, in this embodiment, the following steps are further set after step S100:

[0089] Step S400: When the temperature of the slurry in the crushing chamber is between the first preset temperature and the second preset temperature, perform the second heating process and adjust the heating power P to be lower than the rated heating power P0. By controlling the temperature of the slurry in the crushing chamber to adjust the heating power during the second heating process, the foam generated on the surface of the slurry is always kept in a small amount and does not touch the air holes 321. In this way, not only can the temperature for material ripening be slightly increased to accelerate the ripening of the material, but also the overflow of slurry at the air holes 321 can be avoided and the pulping cycle can be shortened as much as possible.

[0090] It should be noted that in this embodiment, the sequence of steps S200 and S400 is not specifically limited.

[0091] Furthermore, in this embodiment, the setting of the heating power P is also associated with the rated heating power P0 of the food processor, the first preset temperature T1, and the slurry temperature T. Specifically, taking P0 = 1000w as the dividing line, it can be divided into the following two cases:

[0092] Case 1: When P0 ≤ 1000w, it is necessary to determine whether to perform the first heating process or the second heating process according to the relationship between T and T1. If so, determine the heating power P at which to perform the heating.

[0093] Specifically, when T ≥ T1, during the pulping process, the first heating process and the second heating process are not performed, and there is no need to configure the heating power P;

[0094] When T1 - 5 ≤ T < T1, it is equivalent to a situation where the temperature is lower than the first preset temperature T1 but higher than the second preset temperature. At this time, during the pulping process, the second heating process is performed, and the heating power P = 1 / 3P0 is configured;

[0095] When T1 - 10 ≤ T < T1 - 5, it is equivalent to a situation where the temperature is lower than the first preset temperature T1 but higher than the second preset temperature T2. That is to say, in this case, compared with the situation of T1 - 5 ≤ T < T1, the first preset temperature T1 and the second preset temperature T2 are higher, that is, the relative altitude is higher. In this case, during the pulping process, the second heating process is performed, and the heating power P = 1 / 2P0 is configured;

[0096] When T < T1 - 10, it is equivalent to being lower than the second preset temperature T2. At this time, during the pulping process, the first heating process is performed, and the heating power P = P0 is configured to quickly ripen the material without prolonging the pulping cycle while preventing overflow.

[0097] Case 2: When P0 > 1000w, it is necessary to determine whether to perform the first heating treatment or the second heating treatment according to the relationship between T and T1. If so, determine the heating power P at which to perform the heating.

[0098] Specifically, when T ≥ T1, during the pulping process, the first heating treatment and the second heating treatment are not performed, and there is no need to configure the heating power P;

[0099] When T1 - 5 ≤ T < T1, it is equivalent to a situation where the temperature is lower than the first preset temperature T1 but higher than the second preset temperature. At this time, during the pulping process, the second heating treatment is performed, and the heating power P = 1 / 4P0 is configured;

[0100] When T1 - 10 ≤ T < T1 - 5, it is equivalent to a situation where the temperature is lower than the first preset temperature T1 but higher than the second preset temperature. That is to say, in this case, compared with the situation of T1 - 5 ≤ T < T1, the first preset temperature T1 and the second preset temperature are higher, that is, the relative altitude is higher. In this case, during the pulping process, the second heating treatment is performed, and the heating power P = 1 / 3P0 is configured;

[0101] When T < T1 - 10, it is equivalent to being lower than the second preset temperature. At this time, during the pulping process, the first heating treatment is performed, and the heating power P = 1 / 2P0 is configured to quickly ripen the material without prolonging the pulping cycle while preventing overflow.

[0102] In a preferred embodiment, both the first heating treatment and the second heating treatment are intermittent heating treatments. However, there are differences in heating power, heating duration, etc.

[0103] Example 3

[0104] The difference between this embodiment and Embodiment 1 is that instead of determining the formation of a V-shaped liquid surface by judging that the crushing device 21 reaches the actual maximum crushing speed, the heating device 4 is controlled to perform the heating treatment after the motor 11 starts and runs for a certain period of time. Preferably, the heating device 4 is controlled to perform the heating treatment after the motor 11 starts and runs for 3 - 10 seconds.

[0105] Further, in order to avoid the problem that the time for the slurry to form a V-shaped liquid level is too long, which prolongs the pulping cycle, and / or to avoid the problem that after the heating treatment stops, the motor 11 stops too quickly, causing the remaining temperature of the slurry to prevent the foam from being eliminated in time, that is, the foam is still at a relatively high position or overflows from the air vent 321, the working duration of a single stirring is set to t0, and the interval duration from the start of the motor 11 to the start of the first heating treatment is Δt1. That is, the duration for the crushing device 21 in the crushing chamber to rotate to make the slurry form a V-shaped liquid level is Δt1, and Δt1 is equivalent to 3 - 10 seconds after the motor 11 starts. The interval duration from the stop of the first heating treatment to the stop of the motor 11 is Δt2, and 3 / 5 ≤ Δt1 / Δt2 ≤ 10 / 3.

[0106] On the one hand, in order to avoid the problem that when the ratio of the sum of Δt1 and Δt2 to the working duration of a single stirring is too small, the value of Δt1 is too small and the time for the slurry to form a V-shaped liquid level is insufficient, or the value of Δt2 is too small, to avoid the problem that after the first heating treatment (or the second heating treatment) stops, the motor 11 stops too quickly, causing the remaining temperature of the slurry to prevent the foam from being eliminated in time, that is, the foam is still at a relatively high position or overflows from the air vent 321. On the other hand, in order to avoid the problem that when the ratio of the sum of Δt1 and Δt2 to the working duration of a single stirring is too large, the time for the first heating treatment (or the second heating treatment) is too long and the ingredients cannot be fully boiled, 3 / 25 ≤ (t1 + Δt) / t0 ≤ 1 / 2 is set.

[0107] Preferably, the preset value of t0 is approximately between 20 - 50 seconds, and the value of t2 is approximately between 3 - 5 seconds.

[0108] Embodiment 4

[0109] The difference between this embodiment and Embodiment 1 is that the first heating treatment is set to continuous heating. That is to say, when there are multiple stirrings during the pulping process, during a single stirring, the heating device 4 performs continuous heating. However, it should be noted that the heating power should be ensured to avoid the problem of slurry overflow during a single stirring, that is, it is performed at a relatively small power. In the same stirring, the product of the actual heating power and the actual heating achieved in Embodiment 1 is equal to the product of the actual heating power and the actual heating achieved in this embodiment to ensure that there will be no slurry overflow.
