Description

Technical Field

[0001] The invention relates to the field of food processing, and in particular to a stewing method. Background Art

[0002] As the quality of life improves, consumers' requirements for food processors also increase. Among them, most existing food processors are equipped with pure heating functions for stewing, such as cooking porridge, Tremella and lotus seed soup, rock sugar and snow pear, etc. If the materials are beaten at high speed for a long time during the stewing process, they will be crushed, resulting in poor stewing effect and poor user experience. Therefore, when using the above-mentioned stewing function, the method of not beating the materials during the stewing process is often adopted; however, when users use the stewing function of the food processor, there is a high possibility of adding a large amount of sugar. If a large amount of sugar is added to the food processor and the food processor does not respond to it, but stews normally, there will be many problems, such as: the slurry temperature is not enough to boil effectively during the stewing cycle, resulting in poor stewing effect and poor user experience; at the same time, stewing ingredients with a large amount of sugar will also cause the bottom of the processing cavity of the food processor to be sticky and cause the heating plate thermostat to trip and then cause abnormal alarm risks. However, in the prior art, food processing machines such as food processors cannot effectively detect whether a large amount of sugar is added to the processing chamber of the food processing machine, so that the food processing machine cannot respond to it.

[0003] In the prior art, there are patents with application numbers 201710055893.3 and 201710055892.9, which disclose solving the problem of bottom sticking by intermittently heating the ingredients and extending the heating cycle. However, the above schemes cannot identify whether sugars or other substances that may cause bottom sticking are added to the processing chamber. Therefore, the above schemes indiscriminately extend the heating cycle during implementation, that is, as long as the ingredients are processed, the ingredients are intermittently heated and the heating cycle is extended, resulting in low cooking efficiency and long time consumption when sugars or other substances that may cause bottom sticking are not added, which reduces user experience.

[0004] Therefore, when users use the stewing function of the food processor and put in a large amount of sugar substances, the food processor cannot accurately identify the large amount of sugar substances, which may cause the pulp temperature to be insufficient during the pulping cycle and the bottom of the processing chamber to be burnt, resulting in poor user experience and becoming a technical problem that needs to be solved urgently. Summary of the invention

[0007] As an optional embodiment, the food processor also includes a stirring device; the second heating stage also includes: obtaining the slurry temperature T in the processing chamber in real time; determining whether the stirring device starts stirring based on the relationship between the slurry temperature T and the slurry preset temperature T0; wherein, if T≥T0, the main control module controls the stirring device to stir the mixture in the processing chamber.

[0008] As an optional embodiment, the food processor also includes a stirring device; the second heating stage also includes: real-time acquisition of the heating time t of the first heating stage; determining whether the stirring device starts stirring based on the relationship between the heating time t and the preset heating time t0; wherein, if the heating time t reaches the preset heating time t0, the main control module controls the stirring device to stir the mixture in the processing chamber.

[0009] As an optional embodiment, the second heating stage also includes: if the heating time t does not reach the preset heating time t0, determining whether the stirring device starts stirring based on the relationship between the slurry temperature T and the preset slurry temperature T0; wherein, if T≥T0, the main control module controls the stirring device to stir the mixture in the processing chamber.

[0010] As an optional embodiment, the food processor further includes a stirring device; and the second heating stage further includes: determining the rotation speed of the stirring device based on the capacity of the processing cavity, and the capacity of the processing cavity is proportional to the rotation speed of the stirring device.

[0011] As an optional implementation, the preset heating time t0 is determined based on the capacity of the processing chamber and the rated heating power, wherein 5 min≤t0≤15 min.

[0012] As an optional implementation manner, the preset temperature rise rate is determined based on the first power, and the preset temperature rise rate is proportional to the first power.

[0013] As an optional implementation, the second power is determined based on the rated power; when the rated power is in the first power range, the second power is one third of the rated power; when the first power is in the second power range, the second power is one half of the rated power; when the first power is in the third power range, the second power is equal to the rated power.

[0014] As an optional embodiment, the food processor also includes a stirring device; the second heating stage also includes: determining whether the temperature change within a preset time period is less than a preset change; if the temperature change within the preset time period is less than the preset change, the main control module controls the stirring device to perform secondary stirring.

[0015] As an optional implementation, the total duration t1 of the stewing method is the sum of the duration of the preheating stage and the duration of the stewing stage, and the total stirring duration t2 of the stirring device is ≤0.05t1.

Through this method, the main control module can make an accurate judgment on whether a large amount of sugar substances are added to the processing chamber in the first heating stage of the preheating stage, and enter the second heating stage after identifying whether a large amount of sugar substances are added to the processing chamber. The mixed material is processed, and even if the second power of the second heating stage is less than or equal to the first power, the power is reduced so that the mixture including a large amount of sugars is fully mixed, the sugar substances are evenly distributed in the mixture as much as possible, and the problems of insufficient pulp temperature and sticky bottom of the processing chamber during the pulping cycle are avoided as much as possible. At the same time, when it is determined that a large amount of sugar substances are not added to the processing chamber, that is, when the temperature rise rate of the mixture in the processing chamber is less than or equal to the preset temperature rise rate, the main control module controls the food processor to enter the stewing stage, which shortens the cooking time of the food processor when a large amount of sugar substances are not added to the processing chamber, improves the cooking efficiency, and then improves the user experience and the practicability of the food processor.

[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0023] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0024] Referring to the background technology, when the user uses the stewing function of the food processor, there is a great possibility that a large amount of sugar will be added when placing the ingredients. When a large amount of sugar is added into the food processor and the food processor does not respond to this and instead stews normally, there will be many problems, for example: the slurry temperature is not enough during the stewing cycle and cannot boil effectively, resulting in poor stewing effect of the material and poor user experience. Specifically, the detection temperature sensor of the food processor is usually arranged at the bottom of the processing cavity. When the user places a large amount of sugar, the sugar substance will melt during the heating process to form sugar liquid, separate from the water layer, and gather at the bottom of the processing cavity. Then, the temperature value detected by the main control module will have a significant deviation from the actual slurry temperature and will be significantly higher than the actual slurry temperature. Then, when the main control judges that the slurry temperature of the cavity has reached the boiling temperature point, the actual slurry temperature is lower than the boiling temperature point, resulting in low temperature of the material in the cavity during the stewing cycle and unable to boil effectively; at the same time, stewing ingredients with a large amount of sugar will also cause the bottom of the processing cavity of the food processor to become sticky and cause the heating plate thermostat to trip and thus cause the risk of abnormal alarm. However, in the prior art, the food processor cannot effectively detect whether a large amount of sugar is added to the processing chamber of the food processor, so that the food processor cannot respond to it.

[0025] Based on this, Figure 1-2 As shown, the present application provides a stewing method, which is applied to a food processor for making sweet drinks, characterized in that the food processor includes a processing cavity and a main control module, and the stewing method includes:

[0026] S1 preheating stage;

[0027] S2 stewing stage;

[0028] The preheating stage comprises:

[0029] S101, a first heating stage, heating the processing cavity with a first power P1 to mix the liquid in the processing cavity with the food to form a mixture;

[0030] S102, a second heating stage, heating the processing cavity with a second power P2 to heat and stew the mixture;

[0031] Among them, P1≥P2; in the first heating stage, the temperature rise rate V1 of the mixture is obtained in real time, and the temperature rise rate V1 of the mixture is compared with the preset temperature rise rate V0 to determine whether a large amount of carbohydrate substances are added to the processing cavity, and the preset temperature rise rate V0 is the temperature rise rate under the minimum stewing capacity of the processing cavity; if V1>V0, it is determined that a large amount of carbohydrate substances are added to the processing cavity, and the main control module controls the food processor to enter the second heating stage; if V1≤V0, the main control module controls the food processor to enter the stewing stage.

[0032] Specifically, in the first heating stage, the temperature rise rate of the mixture in the processing chamber is compared with the preset temperature rise rate to determine whether a large amount of sugar substances are added to the processing chamber, wherein if the temperature rise rate of the mixture in the processing chamber is greater than the preset temperature rise rate, it is determined that a large amount of sugar substances are added to the processing chamber. Through this method, the main control module can make an accurate judgment on whether a large amount of sugar substances are added to the processing chamber in the first heating stage of the preheating stage, and enter the second heating stage after identifying whether a large amount of sugar substances are added to the processing chamber, and process the mixture with a large amount of sugar substances added, that is, the second power of the second heating stage is less than or equal to the first power, and the power is reduced. The main control module can adaptively reduce the heating power to avoid the bottom of the cup body from heating at high power. In order to solve the problem of burnt bottom and thermostat tripping caused by excessive temperature rise, the temperature can be slowly raised by reducing the heating power, the sugar can be melted, the slurry temperature can be slowly evenly heated, and the material can float up. The slurry temperature can be heated to the set temperature point and then stirred for even temperature, so as to ensure the stewing effect, improve the user experience, and avoid the possible problems of insufficient slurry temperature and burnt bottom of the processing chamber during the slurrying cycle. At the same time, when it is determined that a large amount of sugar substances are not added to the processing chamber, that is, the temperature rise rate of the mixture in the processing chamber is less than or equal to the preset temperature rise rate, the main control module controls the food processor to enter the stewing stage, which shortens the cooking time of the food processor when a large amount of sugar substances are not added to the processing chamber, improves the cooking efficiency, and then improves the user experience and the practicality of the food processor.

[0033] It should be understood that the temperature rise rate of the mixture in the processing chamber is the ratio of the temperature rise value within a certain period of time to a certain period of time. The present application does not limit the specific period of time used for the specific temperature rise rate and the specific temperature rise value. The specific period of time can be set according to the rated power of the food processor. For example, when the rated power W0≥1500w, the specific period of time can be 60 seconds; when 800w≤W0<1500w, the specific period of time can be 90 seconds; when W0<800w, the specific period of time can be 120 seconds; at the same time, the temperature rise value within the specific period of time referred to by the preset temperature rise rate can be 20°C. If the rated power of the food processor is 1800w, the preset temperature rise rate is 20°C / 60s, which is 0.3333°C / s.

[0034] As an optional implementation manner, the preset temperature rise rate is determined based on the first power, and the preset temperature rise rate is proportional to the first power.

[0035] As an optional implementation, the second power is determined based on the rated power; when the rated power is in the first power range, the second power is one third of the rated power; when the first power is in the second power range, the second power is one half of the rated power; when the first power is in the third power range, the second power is equal to the rated power.

[0036] Specifically, the main control module can configure different heating powers according to different rated powers, which can not only avoid the problem of the bottom of the cup body being burnt due to excessive temperature rise and the thermostat tripping, but also ensure that the overall heating time deviation is not large, ensuring user experience and machine reliability. This improves the practicality and intelligence of the food processor.

[0037] In the second heating stage, the main control module can adaptively reduce the heating power to avoid the problem of burnt bottom and thermostat tripping caused by rapid temperature rise at the bottom of the cup during high-power heating. The temperature can be slowly raised by reducing the heating power to melt the sugar, slowly evenly heat the slurry, and float the material. The slurry is heated to the set temperature point and then stirred to evenly heat the slurry, ensuring the stewing effect and improving the user experience. In the second heating stage, the main control module can configure different heating powers according to different rated powers, which can not only avoid the problem of burnt bottom and thermostat tripping caused by rapid temperature rise at the bottom of the cup, but also ensure that the overall heating time deviation is not large, thus ensuring the user experience and the reliability of the machine.

[0038] As an optional embodiment, the food processor also includes a stirring device; the second heating stage also includes: obtaining the slurry temperature T in the processing chamber in real time; determining whether the stirring device starts stirring based on the relationship between the slurry temperature T and the slurry preset temperature T0; wherein, if T≥T0, the main control module controls the stirring device to stir the mixture in the processing chamber.

[0039] By stirring the slurry in the second heating stage, the sugar substances gathered at the bottom can be further mixed with the slurry, which can effectively reduce the impact of adding a large amount of sugars on the temperature detected by the temperature sensor at the bottom of the processing chamber; the sugar substances and the slurry are quickly and evenly mixed, which increases the dissolution rate of the sugar substances, thereby reducing the duration of the second heating stage and shortening the entire stewing time to a certain extent; determining whether the stirring device starts stirring based on the relationship between the slurry temperature T and the preset slurry temperature T0 can ensure the stewing effect of the material, improve the user experience, and enhance the intelligence of the machine.

[0040] Specifically, when the slurry temperature T is greater than or equal to the preset slurry temperature T0, the stirring device can be controlled to operate at a first preset stirring speed for a first preset stirring time, wherein the preset slurry temperature T0 can be determined based on the heating rated power, thereby ensuring that the sugar at the bottom of the cup is fully dissolved while avoiding the problem of sticky bottom and thermostat tripping due to excessive temperature, thereby ensuring the stewing effect of the materials, improving user experience, and enhancing the intelligence of the machine.

[0041] As an optional embodiment, the food processor also includes a stirring device; the second heating stage also includes: real-time acquisition of the heating time t of the first heating stage; determining whether the stirring device starts stirring based on the relationship between the heating time t and the preset heating time t0; wherein, if the heating time t reaches the preset heating time t0, the main control module controls the stirring device to stir the mixture in the processing chamber.

[0042] Specifically, it should be understood that the present application does not limit the heating method in the first heating stage. The food can be heated by continuous heating or by intermittent heating. At the same time, the present application does not limit the specific setting method of the preset heating time t0. If the food is heated by continuous heating in the first heating stage, then there may be one or more time periods with a duration of t0 in the first heating stage. When the duration of continuous heating starting at a specified time reaches t0, it is considered that the heating time t reaches the preset heating time t0. If the food is heated by intermittent heating in the first heating stage, then the preset heating time t0 may refer to the duration including the duration of stopping heating in the intermittent heating cycle, or it may only refer to the heating time in the intermittent heating cycle.

[0043] As an optional implementation, the preset heating time t0 is determined based on the capacity of the processing chamber and the rated heating power, wherein 5 min≤t0≤15 min.

[0044] Specifically, when the heating time is greater than or equal to the preset heating time, the stirring device can be controlled to operate at a second preset stirring speed for a second preset stirring time, wherein the preset heating time is determined based on the capacity of the processing chamber and the rated heating power, and when the user places a large amount of sugar to melt and form sugar solution and water layers during the heating process, a sugar layer is formed as the sugar dissolves, and the material basically floats on the sugar layer when heated to the preset time, and stirring is configured during the preset heating time in the first stage, and the sugar solution is broken up by stirring, so that the temperature of the mixture is balanced, and a uniform temperature can be achieved before the mixture reaches the boiling temperature point, while ensuring that the stewing time cycle remains basically unchanged, and the low-speed stirring of the motor can meet the requirements of breaking up the sugar layer to achieve a uniform temperature without hitting the material, thereby ensuring the integrity of the material, ensuring the stewing effect of the material, improving the user experience, and enhancing the intelligence of the machine.

[0045] In addition, the first preset stirring time can be determined according to the capacity of the processing chamber of the food processor. For example, when the capacity of the processing chamber is above 900 ml, the first preset stirring time can be set to 5 seconds. When the capacity of the processing chamber is within 900 ml, the first preset stirring time can be set to 3 seconds.

[0046] In addition, it should be noted that the second preset stirring speed and the second preset stirring time may be equal to or not equal to the first preset stirring speed and the first preset stirring time, respectively, and this application does not impose any limitation on this.

[0047] As an optional embodiment, the second heating stage also includes: if the heating time t does not reach the preset heating time t0, determining whether the stirring device starts stirring based on the relationship between the slurry temperature T and the preset slurry temperature T0; wherein, if T≥T0, the main control module controls the stirring device to stir the mixture in the processing chamber.

[0048] Specifically, when the heating time is less than the preset heating time and the slurry temperature T is greater than or equal to the preset slurry temperature T0, the stirring device can be controlled to operate at a third preset stirring speed for a third preset stirring time, wherein the preset slurry temperature T0 can also be determined based on the heating rated power. When the heating time is less than the preset heating time and the slurry temperature T is greater than or equal to the preset slurry temperature T0, the stirring device is controlled to stir, thereby ensuring that the sugar at the bottom of the cup is fully dissolved while avoiding the problem of burnt bottom and thermostat tripping due to excessive temperature, further ensuring the stewing effect of the materials, improving user experience, and enhancing the intelligence of the machine.

[0049] It should also be noted that the third preset stirring speed and the third preset stirring time may be equal to or not equal to the first preset stirring speed, the second preset stirring speed and the first preset stirring time, the second preset stirring time, respectively, and this application does not impose any limitation on this.

[0050] As an optional implementation, the rotation speed of the stirring device is determined based on the capacity of the processing chamber, and the capacity of the processing chamber is proportional to the rotation speed of the stirring device.

[0051] It is understandable that the larger the capacity of the processing cavity is, the greater the required rotation speed of the stirring device is, so as to increase the temperature uniformity rate of the food processor in the second heating stage and improve the practicality of the food processor.

[0052] As an optional embodiment, the food processor also includes a stirring device; the second heating stage also includes: determining whether the temperature change within a preset time period is less than a preset change; if the temperature change within the preset time period is less than the preset change, the main control module controls the stirring device to perform secondary stirring.

[0053] Specifically, in the second heating stage, the main control module can detect the temperature change during stirring within a certain period of time in real time, and compare the temperature change with the preset change to determine: the uniform temperature state of the mixture in the processing chamber is determined by the size of the temperature change within the preset period of time, that is, whether the large amount of sugar added to the processing chamber has been evenly dissolved in the processing chamber. When the temperature reduction within the preset period of time is less than the preset change, it can be considered that the mixture in the processing chamber is not in a uniform temperature state. At this time, the main control module can control the stirring device to perform secondary stirring, which can further promote the dissolution of a large amount of sugar in the processing chamber, so that the mixture in the processing chamber reaches a uniform temperature state, ensuring that the sugar at the bottom of the cup body is fully dissolved while avoiding the problem of excessive temperature causing the bottom to be sticky and the thermostat to trip, further ensuring the stewing effect of the material, improving the user experience, and enhancing the intelligence of the machine.

[0054] In addition, when the temperature drop within the preset time is greater than or equal to the preset change, it can be considered that the slurry temperature is fully averaged, and the main control module controls the food processor to enter the stewing stage; the preset change can be set to 20°C, which needs to be set according to the different parameters of the food processor. The main control module can confirm the effectiveness of the average temperature by detecting the temperature change amplitude during stirring, avoiding differences in the average temperature effect caused by different materials placed by users, different working conditions, and differences in the machine itself, ensuring a good stewing effect, improving user experience, and improving the intelligence of the food processor.

[0055] As an optional implementation, the total duration t1 of the stewing method is the sum of the duration of the preheating stage and the duration of the stewing stage, and the total stirring duration t2 of the stirring device is ≤0.05t1.

[0056] Specifically, by setting a low stirring rate, it is possible to avoid the ingredients being broken by the stirring device to a certain extent, retaining the integrity of the ingredients, further improving the cooking effect of the food processor, and improving the user experience.
