[0051] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0052] It should be noted that the terms "first," "second," etc., used in this application can be used to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish the first element from the second element. The terms "comprising" and "having," and any variations thereof, used in this application, are intended to cover non-exclusive inclusion. The term "multiple" used in this application refers to two or more. The term "and / or" used in this application refers to one of the embodiments, or any combination of multiple embodiments.

[0053] In existing technologies, food processing equipment equipped with self-cleaning functions, such as blenders and soy milk makers, typically relies on preset fixed programs for their self-cleaning process. For example, regardless of whether the residue inside the container is light juice stains or heavy grain residue, the food processing equipment performs the same cleaning steps: driving the ultrasonic generator to run for a fixed duration with a fixed ultrasonic power, and / or agitating the device a fixed number of times with a fixed drive motor speed. This self-cleaning strategy, which relies on preset fixed programs, has significant drawbacks. It lacks flexibility and cannot adapt to differences in the actual degree of dirt. When dealing with light stains, a fixed-intensity cleaning program wastes energy and water resources and may accelerate the wear and tear on components such as the ultrasonic transducer and drive motor due to unnecessary prolonged high-intensity operation. Conversely, when dealing with severe or sticky stains, a fixed-intensity cleaning program may be insufficient, resulting in incomplete cleaning and forcing users to perform a second manual cleaning. Therefore, how to make the self-cleaning process of food processing equipment more flexible has become an urgent technical problem to be solved.

[0054] In one exemplary embodiment, a self-cleaning control method for food processing equipment is provided. This method is applicable to various types of food processing equipment and can be specifically implemented in the control unit of the food processing equipment. As an example, the control unit of the food processing equipment can specifically be the control motherboard of the food processing equipment. The food processing equipment can be kitchen equipment such as a soymilk maker, a high-speed blender, a mixer, or a dough mixer, and it has a self-cleaning function. The food processing equipment is equipped with an ultrasonic generator, as described above. Figure 1 The self-cleaning control method for food processing equipment provided in this application embodiment specifically includes the following steps S110 to S130.

[0055] S110: Acquire cleaning load signal when the food processing equipment is in self-cleaning mode.

[0056] Among them, the cleaning load signal is an electrical signal that reflects the cleaning load status, and the cleaning load signal includes the operating current signal of the ultrasonic generator.

[0057] Specifically, when the food processing equipment enters and is in self-cleaning mode, the control unit acquires a cleaning load signal. In some embodiments, the control unit enters self-cleaning mode upon receiving a self-cleaning command from the user. As an example, the user can issue a self-cleaning command to the food processing equipment via an interactive device installed on the equipment or a wired controller associated with the equipment.

[0058] The cleaning load signal is an electrical signal reflecting the cleaning load condition, specifically the level of dirt or grime within the food container of the food processing equipment. The cleaning load signal can originate from various sensing or detection mechanisms within the food processing equipment. In some embodiments, the food processing equipment includes an ultrasonic generator. When the food processing equipment is in self-cleaning mode, a cleaning solution or water-based liquid medium is present in the food container. The ultrasonic generator emits ultrasonic waves, creating a cavitation effect in the liquid medium, thereby achieving self-cleaning of the food processing equipment. In this embodiment, the cleaning load signal includes the operating current signal of the ultrasonic generator.

[0059] The control unit is connected to the ultrasonic generator to obtain the operating current signal of the ultrasonic generator. As an example, the ultrasonic generator is equipped with a current sensor, which is used to collect the operating current signal of the ultrasonic generator. The control unit obtains the operating current signal of the ultrasonic generator through the current sensor.

[0060] The operating current signal of an ultrasonic generator can indirectly reflect the cleaning load of food processing equipment. Specifically, when an ultrasonic generator operates in a liquid medium, its operating voltage and vibration frequency remain at their rated values, while the load of its output mechanical vibration (ultrasound) varies depending on the concentration and properties of suspended or attached contaminant particles in the liquid medium. When the food container of the food processing equipment is heavily contaminated, the density and viscosity of the liquid medium increase, increasing the resistance experienced by the transducer of the ultrasonic generator. Since the operating voltage of the ultrasonic generator remains at its rated value, the operating current of the ultrasonic generator increases accordingly to maintain the rated vibration frequency. Conversely, during cleaning, as the amount of contaminant decreases, the operating current tends to decrease. Therefore, the operating current signal of the ultrasonic generator can indirectly reflect the cleaning load.

[0061] In some embodiments, the food processing equipment is equipped with optical sensors for detecting stains, and the cleaning load signal can also be an electrical signal generated by these optical sensors. In this case, the cleaning load signal directly reflects the cleaning load status. In some embodiments, the cleaning load signal can also be an electrical signal exhibited by an element performing a self-cleaning function due to changes in its cleaning load during operation. For example, if the food processing equipment is equipped with an ultrasonic generator for self-cleaning, the cleaning load signal can be the operating power signal of the ultrasonic generator. In this case, the cleaning load signal also indirectly reflects the cleaning load status.

[0062] S120: Adjust at least one cleaning intensity parameter in self-cleaning mode according to the cleaning load signal.

[0063] Among them, the cleaning intensity parameter is used to control the cleaning intensity when food processing equipment performs self-cleaning.

[0064] Specifically, the control unit adjusts at least one cleaning intensity parameter in the self-cleaning mode according to the cleaning load signal. The cleaning intensity parameter is used to control the cleaning intensity when the food processing equipment performs self-cleaning. There may be one or more cleaning intensity parameters, which are specifically the operating parameters of the components of the food processing equipment that perform the self-cleaning function when they are working.

[0065] The specific cleaning intensity parameters adjusted by the control unit depend on the specific structure of the food processing equipment and the type of components that perform the self-cleaning function. For example, if the food processing equipment is equipped with an ultrasonic generator to perform the self-cleaning function, the cleaning intensity parameters could include the ultrasonic generator's operating power, operating voltage, operating time, and so on. Similarly, if the food processing equipment is equipped with a water pump to spray water and perform the self-cleaning function, the cleaning intensity parameters could include the water pump's operating power, operating voltage, operating time, and so on. Furthermore, if the food processing equipment's drive motor rotates its connected rotating blade during the self-cleaning function, further enhancing the self-cleaning process, the cleaning intensity parameters could also include the drive motor's operating power, operating voltage, operating time, and so on.

[0066] After receiving the cleaning load signal, the control unit can roughly sense the current cleaning load situation. Correspondingly, the control unit adjusts the cleaning intensity parameter based on the cleaning load situation, thereby changing the cleaning intensity during the self-cleaning process of the food processing equipment. In some embodiments, after processing the cleaning load signal, the control unit determines the current cleaning load situation into three levels: general dirt, moderate dirt, and very dirty, and adjusts the cleaning intensity parameter accordingly. For example, when the current cleaning load situation is very dirty, the control unit adjusts the cleaning intensity parameter to ensure that the cleaning intensity during the self-cleaning process of the food processing equipment is at the highest level, thus addressing the current very dirty cleaning load situation.

[0067] S130: Controls food processing equipment to perform self-cleaning based on cleaning intensity parameters.

[0068] Specifically, after the control unit completes the adjustment of the cleaning intensity parameters, it sends control commands to the components of the food processing equipment that perform the self-cleaning function, so that each component works according to the corresponding cleaning intensity parameters and controls the food processing equipment to perform self-cleaning.

[0069] In the aforementioned self-cleaning control method for food processing equipment, when the food processing equipment is in self-cleaning mode, a cleaning load signal reflecting the cleaning load is acquired, and at least one cleaning intensity parameter in the self-cleaning mode is adjusted based on the cleaning load signal, thereby controlling the cleaning intensity when the food processing equipment performs self-cleaning. In this embodiment, the cleaning load signal may include the operating current signal of the ultrasonic generator. Through the technical solution provided by this application, the acquired cleaning load signal can reflect the current cleaning load of the food processing equipment, that is, it can basically determine the actual dirt level of the food processing equipment. Based on the actual dirt level of the food processing equipment, the cleaning intensity of self-cleaning in the self-cleaning mode is adjusted accordingly, solving the technical problem of poor flexibility in the self-cleaning of food processing equipment in the prior art.

[0070] In some feasible embodiments, refer to Figure 2 S120 specifically includes S210 to S220.

[0071] S210: When the food processing equipment is in the first self-cleaning stage of self-cleaning mode, the working current value is determined based on the working current signal.

[0072] S220: Adjust the cleaning intensity parameter value according to the operating current value.

[0073] Specifically, the first self-cleaning stage refers to the initial cleaning phase after the food processing equipment enters self-cleaning mode. After entering self-cleaning mode, the equipment will continuously self-clean for a preset time, after which it will exit self-cleaning mode. The preset time can be set by those skilled in the art or by the user, and the self-cleaning period preceding this preset time constitutes the first self-cleaning stage. For example, if the preset time is 15 minutes, then the first 10 minutes constitute the first self-cleaning stage. It is understandable that during the first self-cleaning stage, the food container cavity of the food processing equipment is relatively more contaminated.

[0074] When the food processing equipment is in the first self-cleaning stage of self-cleaning mode, the control module analyzes the operating current signal to determine the operating current value of the ultrasonic generator and adjusts the cleaning intensity parameter based on this value. For example, the cleaning intensity parameter may include the operating voltage and operating time of the ultrasonic generator. In this case, a higher operating current value indicates heavier contamination in the food container of the food processing equipment. Therefore, the operating voltage or operating time of the ultrasonic generator can be increased accordingly to improve the cleaning intensity.

[0075] In this embodiment, the operating current signal of the ultrasonic generator is used as the cleaning load signal. The current cleaning load is indirectly reflected through the operating current signal of the ultrasonic generator. The current cleaning load can be clearly perceived without the need for additional sensing devices for detecting dirt. This achieves accurate identification of the current cleaning load while saving costs.

[0076] In some feasible embodiments, prior to S110, the method further includes:

[0077] In response to the self-cleaning command, the cleaning intensity parameter is determined to be a preset initial parameter value.

[0078] Specifically, when the food processing equipment receives the self-cleaning command and begins self-cleaning, the control unit initially sets the operating parameters of the components performing the self-cleaning function, that is, sets the cleaning intensity parameter to the initial parameter value. This initial parameter value is preset by those skilled in the art and stored in the control unit's storage space.

[0079] In some feasible embodiments, refer to Figure 3 S220 specifically includes S310 to S320 as follows.

[0080] S310: When the operating current value is greater than or equal to the preset operating current value threshold, adjust the cleaning intensity parameter value to the first parameter value.

[0081] S320: When the operating current value is less than the operating current value threshold, adjust the cleaning intensity parameter value to the second parameter value.

[0082] The cleaning intensity corresponding to the first parameter value is greater than the cleaning intensity corresponding to the second parameter value.

[0083] Specifically, after determining the operating current value, the control unit compares the operating current value with a preset operating current threshold, and determines the adjustment method for the cleaning intensity parameter based on the comparison result. If the operating current value is greater than or equal to the preset operating current threshold, the cleaning intensity parameter is adjusted to a first parameter value; if the operating current value is less than the operating current threshold, the cleaning intensity parameter is adjusted to a second parameter value. The cleaning intensity corresponding to the first parameter value is greater than the cleaning intensity corresponding to the second parameter value.

[0084] The operating current threshold is preset by those skilled in the art and stored in the storage space of the control unit. The control unit obtains the operating current threshold by direct call.

[0085] The first parameter value and the second parameter value are two different sets of parameters or values. Both the first parameter value and the second parameter value are preset by those skilled in the art and stored in the storage space of the control unit. In some embodiments, the cleaning intensity parameter includes multiple parameters, and the storage space of the control unit pre-stores multiple first parameter values ​​and multiple second parameter values, which are stored according to the type and number of cleaning intensity parameters. As an example, if the cleaning intensity parameter includes the operating voltage and operating time of the ultrasonic generator, then the first parameter value corresponds to the first operating voltage value V1 and the first operating time T1 of the ultrasonic generator, and the second parameter value corresponds to the second operating voltage value V2 and the second operating time T2 of the ultrasonic generator.

[0086] It is understandable that the cleaning intensity produced by the combined effect of the first parameter value is greater than the cleaning intensity corresponding to the second parameter value. For example, in the example above, the first operating voltage value V1 of the ultrasonic generator will be greater than the second operating voltage value V2 of the ultrasonic generator, and the first operating time T1 of the ultrasonic generator will be greater than the second operating time T2 of the ultrasonic generator.

[0087] In this embodiment, the control unit quickly determines the current cleaning intensity parameter value based on the comparison result between the operating current value and the preset operating current value threshold, and controls the cleaning intensity when the food processing equipment performs self-cleaning, so that the food processing equipment can immediately perform self-cleaning with an appropriate cleaning intensity when facing significantly different cleaning loads.

[0088] In some feasible embodiments, refer to Figure 4 S320 and above specifically include S410 to S420.

[0089] S410: Adjust the weights of parameter values ​​based on the operating current value.

[0090] S420: Adjust the second parameter value based on the parameter value and adjust the weight.

[0091] Among them, the parameter adjustment weight is directly proportional to the working current value, the parameter adjustment weight is greater than 0 and less than the preset maximum value of the parameter adjustment weight, and the maximum value of the parameter adjustment weight is greater than 1.

[0092] Specifically, after adjusting the cleaning intensity parameter to the second parameter value, the control unit determines the corresponding parameter adjustment weight based on the operating current value. The parameter adjustment weight corresponds to the operating current value and is directly proportional to it; that is, the larger the operating current value, the larger the parameter adjustment weight. The parameter adjustment weight takes a value within the range of 0 to its maximum value, with the maximum value being greater than 1. As an example, the maximum value of the parameter adjustment weight could be 1.5.

[0093] In some embodiments, the control unit determines the parameter adjustment weight based on a preset working current value-parameter adjustment weight mapping table. This mapping table is predetermined by those skilled in the art and stored in the control unit's storage space. The working current value-parameter adjustment weight mapping table stores the correspondence between working current values ​​and parameter adjustment weights. After the control unit obtains the working current value, it can retrieve the corresponding parameter adjustment weight by looking up the table.

[0094] After determining the parameter value adjustment weight and the second parameter value, the control unit adjusts the second parameter value to obtain the cleaning intensity parameter. As an example, the control unit calculates the product of the second parameter value and the parameter value adjustment weight to adjust the cleaning intensity parameter. In some embodiments, the cleaning intensity parameter includes the operating voltage and operating time of the ultrasonic generator, the second parameter value corresponds to the second operating voltage value V2 and the second operating time T2 of the ultrasonic generator, and the parameter value adjustment weight is K. Therefore, the final determined operating voltage value of the ultrasonic generator is K×V2, and the operating time is K×T2.

[0095] Based on the range of values ​​for the parameter adjustment weight, it can be seen that the parameter adjustment weight can both increase and decrease the value of the second parameter. It is understandable that when the operating current value is less than the operating current threshold, the food container of the food processing equipment is considered to be less contaminated. In this case, a balance between cleaning effectiveness and cleaning power consumption is desired. Therefore, the parameter adjustment weight is set within the range of 0 to its maximum value (greater than 1), allowing the parameter adjustment weight to both increase and decrease the value of the second parameter. When the operating current value is close to the operating current threshold, the second parameter value is appropriately increased to improve cleaning intensity; when the operating current value is far from the operating current threshold, the second parameter value is appropriately decreased to save energy.

[0096] Based on this embodiment, when the parameter adjustment weight is set to 1, the value of the second parameter will not change. At this time, the corresponding operating current value is determined, and this operating current value is set as the threshold value for the balanced operating current value. Therefore, in some embodiments, S320 may further include the following:

[0097] When the operating current value is greater than the balanced operating current value threshold, the parameter adjustment weight is determined based on the operating current value, and the second parameter value is adjusted based on the parameter value adjustment weight to increase the second parameter value; when the operating current value is less than the balanced operating current value threshold, the parameter adjustment weight is determined based on the operating current value, and the second parameter value is adjusted based on the parameter value adjustment weight to decrease the second parameter value.

[0098] In some embodiments, a threshold value for the balanced operating current can be preset, and the threshold value for the balanced operating current is less than the threshold value for the operating current. Based on this, in some embodiments, S220 may further include:

[0099] When the operating current value is greater than or equal to the preset operating current value threshold, the cleaning intensity parameter is adjusted to the first parameter value; when the operating current value is less than the operating current value threshold but greater than or equal to the balanced operating current value threshold, the cleaning intensity parameter is adjusted to the second parameter value, and the parameter value adjustment weight is determined according to the operating current value, and the second parameter value is adjusted through the parameter value adjustment weight to increase the second parameter value; when the operating current value is less than the balanced operating current value threshold, the cleaning intensity parameter is adjusted to the second parameter value, and the parameter value adjustment weight is determined according to the operating current value, and the second parameter value is adjusted through the parameter value adjustment weight to decrease the second parameter value.

[0100] In this embodiment, when the operating current value is less than the operating current threshold, a parameter adjustment weight is determined based on the operating current value. The second parameter value is then adjusted based on this weight, ensuring that the final determined cleaning intensity parameter better reflects the current cleaning load. Simultaneously, the second parameter value is adaptively increased or decreased based on the range of the parameter adjustment weight. When the operating current value is close to the operating current threshold, the second parameter value is appropriately increased to enhance cleaning intensity; when the operating current value is far from the threshold, the second parameter value is appropriately decreased to save energy, achieving a balance between cleaning effectiveness and energy consumption.

[0101] In some feasible embodiments, refer to Figure 5 S220 also includes S510 to S520.

[0102] S510: When the food processing equipment is in the second self-cleaning stage of self-cleaning mode, the change value of the working current is determined based on the working current signal.

[0103] The second self-cleaning stage is located after the first self-cleaning stage.

[0104] S520: Adjust the cleaning intensity parameter value according to the change in operating current.

[0105] Specifically, the second self-cleaning stage refers to the post-cleaning stage following the first self-cleaning stage in the self-cleaning mode of the food processing equipment. After the equipment enters self-cleaning mode, it will continue self-cleaning for a preset time, after which it will exit self-cleaning mode. The self-cleaning period following this preset time constitutes the second self-cleaning stage. For example, if the preset time is 15 minutes, the first 10 minutes constitute the first self-cleaning stage, and the following 5 minutes constitute the second self-cleaning stage. It is understood that during the second self-cleaning stage, the level of dirt inside the food container of the food processing equipment is relatively lower compared to the first self-cleaning stage. It is also understood that the first and second self-cleaning stages are executed sequentially, with the second stage starting after the first self-cleaning stage concludes.

[0106] In the second self-cleaning stage, the control unit determines the operating current change value based on the operating current signal. In some embodiments, the control unit acquires the operating current signal according to a fixed sampling period. Based on the operating current signal acquired in each sampling period, the control unit determines the operating current change value by calculating the difference between the operating current values ​​within consecutive sampling periods. The operating current change value can be an instantaneous difference, the average of the differences over a period of time, or the slope of the decrease in the operating current value. The operating current change value directly represents the rate at which the cleaning load is reduced per unit time.

[0107] After determining the change in operating current, the control unit dynamically adjusts the cleaning intensity parameter based on the magnitude of the change. For example, if a large change in operating current is detected, it indicates that the stains are being removed rapidly, and the control unit can maintain the current cleaning intensity or make specific adjustments. If the change in operating current is small or approaches zero, it may mean that the self-cleaning process of the food processing equipment is nearing completion or that stubborn stains have been encountered, requiring an adjustment to the strategy.

[0108] As an example, cleaning intensity parameters include the operating voltage and duration of the ultrasonic generator, as well as the operating voltage and duration of the drive motor.

[0109] Understandably, in the second self-cleaning stage, the level of dirt inside the food container of the food processing equipment is relatively better compared to the first self-cleaning stage. At this point, as the cleaning load decreases, the operating current of the ultrasonic transducer is lower, making it more difficult to respond to the cleaning load. Adjusting the cleaning intensity parameter based on the change in operating current ensures the accuracy of the cleaning intensity parameter adjustment and the flexibility to adopt different detection and adjustment strategies according to different stages of self-cleaning.

[0110] In this embodiment, the change in the operating current of the ultrasonic generator reflects the rate of reduction in the cleaning load, thereby allowing the control unit to perceive the actual cleaning status of the food processing equipment in self-cleaning mode. The control unit adjusts the cleaning intensity parameter based on the change in operating current, ensuring that the cleaning intensity matches the real-time cleaning progress during self-cleaning, thus improving the flexibility of self-cleaning.

[0111] In some feasible embodiments, refer to Figure 6 S520 includes the following step S610.

[0112] S610: When the change value of the working current is greater than or equal to the preset threshold value of the change value of the working current, the parameter value of the cleaning intensity parameter is adjusted by a reduction ratio according to the preset parameter value, so as to reduce the cleaning intensity when the food processing equipment performs self-cleaning.

[0113] Specifically, after determining the change in operating current, the control unit compares the change in operating current with a preset threshold value for the change in operating current, and determines how to adjust the cleaning intensity parameter based on the comparison result. If the change in operating current is greater than or equal to the preset threshold value, the cleaning intensity parameter is adjusted by a predetermined reduction ratio to decrease the cleaning intensity during self-cleaning of the food processing equipment.

[0114] The threshold value for the change in operating current is preset by those skilled in the art and stored in the storage space of the control unit. The control unit obtains the threshold value for the change in operating current by direct call.

[0115] In some embodiments, when the control unit adjusts the cleaning intensity parameter value according to a preset reduction ratio, it can determine the reduction weight of the parameter value based on the operating current value, and adjust the cleaning intensity parameter value according to the reduction weight, so as to reduce the cleaning intensity when the food processing equipment performs self-cleaning. The reduction weight of the parameter value takes a value between 0 and 1.

[0116] In some embodiments, when the control unit adjusts the cleaning intensity parameter value according to a preset reduction ratio, it can also gradually adjust the cleaning intensity parameter value according to a preset reduction gradient, so as to reduce the cleaning intensity of the food processing equipment during self-cleaning. The parameter value reduction gradient is a fixed ratio, preset by those skilled in the art; as an example, the parameter value reduction gradient can be 5%.

[0117] In some embodiments, when the control unit adjusts the value of the cleaning intensity parameter according to the preset parameter value reduction ratio, it can do so in a time cycle. In each parameter value reduction cycle, the parameter value of the cleaning intensity parameter is adjusted only once until the change value of the working current is less than the threshold value of the change value of the working current.

[0118] In this embodiment, the cleaning intensity of the food processing equipment during self-cleaning decreases synchronously as the stains are rapidly removed. In the final stage of self-cleaning, the food processing equipment does not require a high cleaning intensity, at which point energy consumption is prioritized. The technical solution provided in this application reduces the cleaning intensity in the second self-cleaning stage, thereby reducing energy consumption and minimizing unnecessary mechanical wear and heat accumulation caused by prolonged high-intensity operation of components used for self-cleaning, such as ultrasonic transducers and drive motors, under low or no cleaning load conditions. This helps to extend the overall service life of the food processing equipment.

[0119] In some feasible embodiments, the food processing equipment further includes a heating unit, and the method further includes the following steps.

[0120] When the preset self-cleaning termination conditions are met, the heating unit is controlled to operate in order to heat and sterilize the food processing equipment.

[0121] The self-cleaning termination condition includes the food processing equipment being in self-cleaning mode for a time greater than or equal to a preset time and / or the change in operating current being less than a preset threshold value for change in operating current.

[0122] Specifically, the control unit continuously determines whether a preset self-cleaning termination condition is met. If the condition is met, the control unit controls the heating unit to operate, heating and sterilizing the food processing equipment. In some embodiments, the self-cleaning termination condition includes the food processing equipment being in self-cleaning mode for a time greater than or equal to a preset time. The preset time is set by those skilled in the art; as an example, the preset duration could be 15 minutes. In some embodiments, the self-cleaning termination condition includes the operating current change value being less than a preset operating current change value threshold. In other embodiments, the self-cleaning termination condition includes the food processing equipment being in self-cleaning mode for a time greater than or equal to a preset time, and the operating current change value being less than a preset operating current change value threshold.

[0123] A heating unit is installed on the food processing equipment and connected to a control unit. The heating unit heats the food container of the food processing equipment to achieve sterilization. As an example, the heating unit can be a heating plate or a heating film. When the control unit determines that the preset self-cleaning termination conditions are met, it sends a control command to the heating unit. The heating unit then heats the liquid medium in the food container according to a preset power and duration, raising its temperature to a level sufficient for sterilization (e.g., above 70°C), thereby sterilizing the food container, rotating blades, and other components of the food processing equipment.

[0124] In this embodiment, the food processing equipment performs self-cleaning followed by heating sterilization, further enhancing the hygiene and safety of the food processing equipment.

[0125] In conjunction with the above embodiments, refer to Figure 7 In the first self-cleaning stage of the self-cleaning mode, the self-cleaning control method for the food processing equipment provided in this application specifically includes the following steps.

In this embodiment, the food processing equipment includes a heating unit.

[0137] S801: Perform the second self-cleaning step.

[0138] S802: Obtain the change value of the operating current of the ultrasonic generator.

[0139] S803: Is the change in operating current greater than or equal to the threshold value for change in operating current?

This ensures that the self-cleaning process does not exceed the maximum working current value of the ultrasonic generator while accelerating the self-cleaning process. Furthermore, the cleaning speed can be maximized by changing the control program without increasing the circuit structure cost.
