Abstract
Description
Technical Field
[0001] This specification relates to the field of food processing machinery technology, and in particular to a pulping method for a food processing machine. Background Technology
[0002] Accurate boiling point temperature is crucial during the pulping process in food processing machines. Boiling point identification technology precisely controls the heating temperature, ensuring ingredients are cooked at their optimal temperature. For example, in making soy milk, accurate boiling point identification allows the food processor to precisely control the heating temperature and time, ensuring proper thermal denaturation of the proteins in the soy milk, creating the necessary conditions for subsequent processing. During pulping, nutrients such as proteins, fats, and carbohydrates undergo thermal denaturation or dissolution at specific temperatures, affecting the taste and nutritional value of the food. Precise temperature control ensures these nutrients are extracted and retained at their optimal state, resulting in a smooth-textured and nutritious product. Furthermore, improper temperature control during pulping can easily lead to safety issues such as spillage and burning. Accurate boiling point identification technology allows the food processor to monitor the heating temperature in real time and adjust the heating power or stop heating when the boiling point is reached, effectively avoiding potential safety risks such as spillage and burning caused by improper temperature control. Therefore, accurate boiling point identification not only ensures that food is cooked at the optimal temperature, enhancing its taste and nutritional value, but also effectively prevents potential safety risks such as overflow and burning caused by improper temperature control, thus protecting the user experience and kitchen safety. Furthermore, boiling points differ at different altitudes, requiring different overflow control measures based on these varying boiling points. The boiling point at low altitudes differs from that at high altitudes; therefore, different boiling point temperatures are needed for overflow prevention at these altitudes. Since food processors themselves do not have altitude recognition capabilities, if the built-in boiling point temperature is the same as the temperature at low altitudes, the actual boiling point of the liquid will be lower than the built-in temperature when used at high altitudes due to the difference between the machine's internal boiling point temperature and the actual boiling point temperature. If the machine still uses the built-in boiling point temperature for overflow prevention, it may not be able to take timely measures to prevent overflow before the actual boiling point is reached, potentially leading to overflow problems.
[0003] Currently, the methods used by food processors on the market, such as high-speed blenders, to determine boiling points have significant drawbacks. For example, patents CN201610605755.3 and CN201610739993.3 use a boiling water method for boiling point identification. After the food processor is powered on, the user chooses whether to trigger the boiling point detection process. When triggered, the water inside the machine is heated, and the current boiling point is identified by detecting changes in the water's temperature. Subsequent processing is then performed based on this boiling point data. While this method can accurately identify boiling points, it is cumbersome and requires additional user intervention. Users are required to add only water without any other ingredients and initiate a special boiling process, increasing their workload. Although detailed operating procedures are provided in the product manuals, users often ignore them and do not follow the instructions when using the machine, meaning they do not perform the additional boiling water operation to determine the boiling point but simply use the food processor directly. If a food processor is used in a high-altitude area, it may be affected by changes in air pressure. If the food processor is started to make pulp without performing the boiling point identification process, the boiling point may be misjudged, leading to overflow, safety hazards, and food waste. Furthermore, the processed food will be far less effective than expected, significantly diminishing the user experience.
[0004] Besides the boiling method, patents CN201610881453.9 and CN201811232446.1 employ methods such as adding boiling point detection hardware. This involves embedding a pressure sensor within the food processing machine to detect the ambient air pressure and determine the boiling point during the pulping process through pressure conversion. While this method provides accurate boiling point data and addresses the issue of boiling point variations at high altitudes to some extent, adding hardware to the food processing machine presents several challenges. First, it increases the production cost of the food processing machine, leading to higher finished product quality and consequently affecting its selling price and market competitiveness. Second, embedding detection hardware places higher demands on the design and processing of the food processing machine. The hardware's placement must accurately detect air pressure while remaining unaffected by other processes, thus requiring high accuracy and stability. Since the boiling point varies with air pressure, insufficient accuracy of the pressure sensor can lead to incorrect boiling point identification. Furthermore, food processors may experience changes in environmental conditions during use, such as temperature and humidity. These changes can affect the stability of the pressure sensor, causing its measurements to drift or fluctuate. If the pressure sensor is not stable enough, the food processor may be unable to accurately control the temperature during heating, potentially leading to safety issues.
[0005] In summary, existing food processing machines require users to perform an additional water boiling operation to determine the boiling point when used at different altitudes. This places high demands on users and results in a poor user experience. If users do not perform the corresponding water boiling process, there are safety risks such as overflow during the pulping process. Summary of the Invention
[0006] This specification provides one or more embodiments of a food processing machine to make a pulp, which solves the following technical problem: When existing food processing machines are used under different altitude conditions, users are forced to perform an additional water boiling operation to determine the boiling point, which places high demands on users and results in a poor user experience. If users do not perform the corresponding water boiling process, there are risk factors that affect the safety of use, such as overflow, during the pulp making process.
[0007] One or more embodiments of this specification employ the following technical solutions:
[0008] This specification provides one or more embodiments of a food processing machine for pulping. Before pulverizing and cooking the material, the food processing machine includes a boiling-holding stage for obtaining the boiling point temperature. The method includes: during the boiling-holding stage, heating the slurry to trigger an overflow signal, detecting the impact resistance temperature, and determining a reference boiling point temperature based on the relationship between the impact resistance temperature and a preset first temperature threshold; ignoring the overflow signal, cyclically heating the slurry using a preset heating method, collecting the real-time slurry temperature after each heating cycle, updating the reference boiling point temperature after each real-time slurry temperature collection, and performing pulverizing and cooking operations after the boiling-holding stage ends; using the latest reference boiling point temperature after the boiling-holding stage ends as the current altitude boiling point temperature.
[0009] Furthermore, after each real-time slurry temperature acquisition, the reference boiling point temperature is updated. Specifically, this includes: in multiple real-time slurry temperature acquisitions, if the real-time slurry temperature acquired in the previous heating is not greater than the reference boiling point temperature, the reference boiling point temperature is maintained after the previous heating ends, and the heating method of the previous heating is maintained in subsequent heatings; if the real-time slurry temperature acquired in the previous heating is greater than the reference boiling point temperature, the reference boiling point temperature is replaced with the real-time slurry temperature acquired in the previous heating ends, and the heating power is lower than that of the previous heating method in subsequent heatings.
[0010] Furthermore, the slurry is circulated and heated in a preset heating method, specifically including: auxiliary heating of the slurry before each heating to heat the slurry temperature to a control point, wherein the control point is the reference boiling point temperature before the current heating.
[0011] Furthermore, the slurry is circulated and heated in a preset heating method, specifically including: the preset heating method is to heat the slurry with a preset heating power for n seconds and then stop for m seconds until the preset first heating duration corresponding to the current heating is met, and then the current heating ends. The first heating duration is an integer multiple of the sum of n seconds and m seconds, and the difference between n and m is not greater than 3 seconds.
[0012] Furthermore, the method further includes: heating the slurry from a first temperature to a second temperature before the boiling stage, and obtaining the heating time; determining the current production capacity based on the heating time; and determining the heating parameters and / or anti-overflow position of the preset heating method in the boiling stage based on the current production capacity.
[0013] Furthermore, the heating parameters include heating power, which is positively correlated with the current production capacity.
[0014] Further, based on the relationship between the anti-collision temperature and the preset first temperature threshold, a reference boiling point temperature is determined, specifically including: when the anti-collision temperature is not less than the first temperature threshold, the anti-collision temperature is used as the reference boiling point temperature; when the anti-collision temperature is less than the first temperature threshold, the overflow signal is ignored, and the slurry is continued to be heated to the first temperature threshold, and the first temperature threshold is used as the reference boiling point temperature.
[0015] Furthermore, during the boiling stage, when the slurry is heated to trigger an overflow signal, the impact protection temperature is detected. Based on the relationship between the impact protection temperature and a preset first temperature threshold, a reference boiling point temperature is determined. Specifically, this includes heating the slurry multiple times, each time heating to trigger an overflow signal, and determining the reference boiling point temperature based on the relationship between the impact protection temperature of the last heating and the first temperature threshold.
[0016] Furthermore, the pulverization and boiling operation includes a heating verification operation to verify the boiling point temperature at the current altitude; during the heating verification operation, the slurry is heated in a preset verification heating method, the overflow signal is ignored, and the real-time slurry temperature is acquired. When the real-time slurry temperature is greater than the boiling point temperature at the current altitude, the boiling point temperature at the current altitude is updated with the real-time slurry temperature.
[0017] Furthermore, ignoring the overflow signal, the slurry is circulated and heated in a preset heating method. When the circulation heating time meets the preset second preset time, the boiling stage ends.
[0018] The above-described at least one technical solution adopted in the embodiments of this specification can achieve the following beneficial effects:
[0019] 1. From an overall perspective, the pulping process involves finely crushing materials, mixing them with water, and boiling them. A boiling-holding stage is incorporated into the pulping process to obtain the boiling point temperature. This simplifies user operation compared to existing technologies, eliminating the need for additional boiling point detection procedures and the tedious extra step of boiling water, thus optimizing the user experience. It also eliminates the safety risks associated with not performing the boiling process. Furthermore, unlike existing technologies, boiling point detection can be achieved during pulping without the need for additional pressure detection components. This can be implemented within existing products, reducing hardware costs and simplifying the food processor's structure; only program-level settings are required. Before crushing and boiling, the boiling point temperature at the current altitude is obtained and used for temperature control during the crushing and boiling stages, ensuring safety during subsequent pulping.
[0020] 2. The actual boiling point temperature is relatively high compared to the impact protection temperature. Based on this, this solution ignores the overflow signal for a relatively short period of time and uses a preset heating method to further increase the slurry temperature in a very short time while ensuring that the slurry does not overflow. By collecting the real-time slurry temperature multiple times, the real-time slurry temperature is made closer to the true boiling point. The highest real-time slurry temperature is used as the boiling point temperature at the current altitude, making the boiling point detection more accurate.
[0021] 3. After the boiling stage, the food processor performs the pulverizing and cooking operation. Since the boiling point temperature has been accurately determined through the boiling stage, the food processor can more precisely control the heating process, including heating temperature, heating time, and heating method. Precise control of the boiling point temperature improves pulping efficiency. Accurate identification of the boiling point temperature also avoids safety hazards such as pulp overflow or scorching caused by excessively high temperatures, ensuring the safety and stability of the food processing process.

[0027] To enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments of this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this specification.
[0028] This specification provides a pulping method for a food processing machine. It should be noted that the executing entity in this specification can be a server, any device with data processing capabilities, or a controller installed in the food processing unit. This specification does not make any specific limitations here. Figure 1 This is a schematic flowchart of a pulping method for a food processing machine provided in an embodiment of this specification, as shown below. Figure 1 As shown, the main steps include the following:
[0029] In step S101, during the boiling stage, when the slurry is heated to the point where an overflow signal is triggered, the collision prevention temperature is detected, and the reference boiling point temperature is determined based on the relationship between the collision prevention temperature and a preset first temperature threshold.
[0030] In one embodiment of this specification, the food processor can be a blender, soymilk maker, mixer, or other hand-washable, automatically water-filling food processor, or it can be any other machine that processes food. Regarding the overflow prevention control process, based on the type of overflow detection, food processors can be divided into those using air-to-air detection and those using overflow electrode detection. For example... Figure 2 , Figure 3 The diagram shown is a structural schematic of a food processing machine based on air-to-air detection provided in an embodiment of this specification. The food processing machine in this example is a food processing device for making soy milk beverage. The food processing machine includes a cup body 1 and a cup lid 2 mounted on the cup body 1. A motor 3 and a temperature sensor (not shown in the figure) are provided at the bottom of the cup body 1. A crushing blade 4 is connected to the end of the rotating shaft driven by the motor 3. A detection plate 5 for air-to-air detection of liquid level is installed on the outer side wall of the glass container inside the cup body. The detection plate 5 is hidden between the glass container and the handle. Figure 3 This is a schematic diagram of the structure of a detection plate provided in an embodiment of this specification, such as... Figure 3 As shown, the side of the detection plate 5 facing the glass container has multiple spaced capacitor plates, for example, capacitor plate 51 is one of the lower capacitor plates. Figure 2 and Figure 3 The food processing machine shown has a different overflow prevention position for each capacitor electrode during overflow detection. By monitoring the capacitance changes of each electrode, it identifies whether the liquid level during the pulping process triggers the overflow prevention level corresponding to that electrode, thus achieving overflow detection. Furthermore, Figure 4 This specification provides a schematic diagram of the structure of a food processing machine based on an anti-overflow electrode, as shown in the embodiments. Figure 4 As shown, the food processor in this example includes a cup body 6, a lid 7, and a base 8. A fixed anti-overflow electrode (not shown) is provided on the lid 7. In... Figure 4 In the spill prevention control process of the food processor shown, one end of the spill prevention electrode is embedded in the cup lid, while the other end is suspended and extends into the cup body. When the spill prevention electrode is heated, the rising slurry conducts electricity to the heating element and triggers the spill prevention signal, thus achieving spill prevention detection. It should be noted that the food processor in the embodiments of this specification is as follows... Figure 2 and Figure 3 The food processing machine shown is based on air-to-air detection.
[0031] In the embodiments of this specification, the food processing machine includes a boiling-holding stage to obtain the boiling point temperature before pulverizing and boiling the material. The boiling-holding stage maintains the slurry temperature near the actual boiling point, softening and sterilizing the material through high temperature. During this process, an anti-overflow signal is used for liquid level detection to prevent overflow, while a temperature signal is used to control the slurry temperature and collect the boiling point. In other words, in the embodiments of this specification, a boiling-holding temperature is set to obtain the current boiling point temperature of the food processing machine, eliminating the need for the user to manually select a boiling process or add extra water before the slurry preparation process, thus reducing additional user operations and greatly improving ease of use. Furthermore, obtaining the boiling point temperature in existing food processing machines does not rely on hardware detection; no additional pressure detection hardware is required, further reducing the manufacturing cost of the food processing machine and enhancing its market competitiveness.
[0032] In one embodiment of this specification, during the set boiling-holding stage, the slurry is heated. When the slurry level reaches the overflow prevention position during the heating process, an overflow prevention signal is triggered. After detecting the overflow prevention signal, i.e., after the slurry level has been heated to the overflow prevention position, the current overflow prevention temperature is collected. Additionally, a detection process for determining the overflow prevention position can be set before the boiling-holding stage. It should be noted that in the steps before heating the slurry in the boiling-holding stage, the slurry is preheated to a set temperature value, typically 87 degrees Celsius. The boiling-holding stage begins at 87 degrees Celsius.
[0033] In the heating process for determining the reference boiling point temperature, a pure heating method using a specified heating power is employed. This specified heating power should not be set too high; a balance between heating rate and thermal inertia must be struck. If the heating power is set too high, the thermal inertia of the slurry may cause a rapid temperature rise, increasing the risk of overflow. Furthermore, excessive power may lead to localized overheating of the slurry, affecting the taste and quality of the food. Conversely, if the heating power is set too low, while reducing the risk of overflow, it will prolong heating time, reduce food processing efficiency, and increase the user's waiting time. For example, to balance heating rate and thermal inertia, a heating power setting of level 6 can be selected. Level 6 provides a moderate heating rate, avoiding both excessively rapid heating that could lead to a rapid temperature rise and increased risk of overflow, and excessively slow heating that could negatively impact the user experience.
[0034] The reference boiling point temperature is determined based on the relationship between the spill prevention temperature (collected when the liquid level is heated to the anti-overflow position) and a preset first temperature threshold. The purpose of adding anti-overflow detection here is to accommodate easily foaming materials present in the pulping process of the food processor. The preset first boiling point temperature can be 91℃ or a pre-set fixed value. In other words, the reference boiling point temperature of the food processor in the current pulping process is determined by the relationship between the spill prevention temperature and the preset first temperature threshold. It is understandable that if only temperature detection is used during the boiling stage, viscous materials may coat the temperature acquisition device, leading to inaccurate temperature readings and potentially causing overflow. Conversely, if only anti-overflow detection is used during the boiling stage, the anti-overflow signal may be interfered with by water vapor or foam, potentially resulting in inaccurate boiling point readings. By detecting both the anti-overflow and temperature signals together, and updating the boiling point throughout the subsequent pulping process, the accuracy of the obtained boiling point temperature can be guaranteed.
[0035] When the slurry is heated to the point where an overflow signal is triggered, the impact protection temperature is detected. Based on the relationship between the impact protection temperature and a preset first temperature threshold, a reference boiling point temperature is determined. Specifically, the slurry is heated multiple times, each time until an overflow signal is triggered. Based on the relationship between the impact protection temperature of the last heating and the first temperature threshold, the reference boiling point temperature is determined.
[0036] When determining the reference boiling point temperature during the boiling stage, the relationship between the spill prevention temperature and the first temperature threshold is referenced. However, in actual spill prevention detection, water vapor interference can occur during the heating process of the food processing machine. Under water vapor interference, the spill prevention signal will still be triggered, but this trigger does not indicate that the actual liquid level has reached the spill prevention position; rather, it is a false spill triggered by water vapor. To ensure the accuracy of the spill prevention temperature, in one embodiment of this specification, the slurry is heated multiple times during the boiling stage. During these multiple heating processes, the slurry is heated to the spill prevention position and the spill prevention signal is triggered. The real-time slurry temperature is then collected to obtain the spill prevention temperature corresponding to each spill prevention signal trigger. The number of heating cycles can be preset and written into the control program, and the slurry is heated according to the preset number of heating cycles. The reference boiling point temperature is determined based on the relationship between the spill prevention temperature of the last heating cycle and the first temperature threshold. Assuming that the number of heating cycles is two, after the first 6-level pure heating ends, wait for 1 minute to allow the near-boiling slurry to gradually stabilize before starting the second 6-level pure heating cycle. The second 6-level heating cycle follows the same processing logic, and then heating is stopped. To ensure the accuracy of temperature data acquisition, temperature data can be collected during the waiting period.
[0037] When determining the reference boiling point temperature during the boiling stage, considering the potential for false overflow due to water vapor interference during the food processing machine's heating process, a method of multiple heating cycles and collecting the overflow temperature at each trigger of the overflow signal is adopted. By repeatedly heating and triggering the overflow signal, multiple overflow temperature data can be collected, providing a more comprehensive reflection of the true temperature state of the slurry near the overflow position. This reduces the random errors that may arise from a single measurement. Multiple measurements can also, to some extent, offset the impact of water vapor interference on the overflow temperature measurement, as water vapor interference is usually random and unpredictable, and multiple measurements can smooth out these random interferences. The reference boiling point temperature is determined based on the relationship between the overflow temperature of the last heating cycle and a first temperature threshold, ensuring that the reference boiling point temperature is derived from temperature data closest to the actual overflow conditions. Furthermore, by calculating the average of multiple overflow temperatures to determine a reference overflow temperature and comparing it with the first temperature threshold, errors can be further reduced, improving the accuracy and reliability of the reference boiling point temperature.
[0038] In addition to the methods described above, the spill prevention temperature can be collected each time the anti-overflow signal is triggered. Based on the multiple spill prevention temperatures corresponding to these triggers, a reference spill prevention temperature can be determined and compared with a first temperature threshold. For example, the reference boiling point temperature can be determined by calculating the average spill prevention temperature of multiple spill prevention temperatures and comparing it with the first temperature threshold.
[0039] Based on the relationship between the impact protection temperature and the preset first temperature threshold, a reference boiling point temperature is determined, specifically including: when the impact protection temperature is not less than the first temperature threshold, the impact protection temperature is used as the reference boiling point temperature; when the impact protection temperature is less than the first temperature threshold, the overflow signal is ignored, and the slurry is continued to be heated to the first temperature threshold, and the first temperature threshold is used as the reference boiling point temperature.
[0040] In one embodiment of this specification, when determining the reference boiling point temperature based on the relationship between the spill prevention temperature and the first temperature threshold, regardless of whether the spill prevention temperature is collected during a single heating cycle, the last spill prevention temperature collected during multiple heating cycles, or the average spill prevention temperature across multiple heating cycles, the overflow prevention signal is ignored after each spill prevention, and the following procedure is followed: If the spill prevention temperature is not less than the first temperature threshold, the spill prevention temperature is directly used as the reference boiling point temperature. That is, if the temperature of the slurry at the overflow prevention position is already higher than or equal to the first temperature threshold, the spill prevention temperature at this time can be used as the reference boiling point temperature for subsequent operations. If the spill prevention temperature is less than the first temperature threshold, the slurry continues to be heated until the slurry temperature reaches the first temperature threshold. In this case, the first temperature threshold, representing the minimum boiling point temperature that the slurry must reach during the heating process, is used as the reference boiling point temperature. By setting a clear first temperature threshold as the minimum boiling point temperature that the slurry must reach during this stage of heating, the temperature control logic can be simplified. When the spill prevention temperature meets or exceeds this threshold, it is directly used as the reference boiling point temperature without the need for complex calculations or adjustments.
[0041] Step S102: Ignore the overflow signal, circulate and heat the slurry using a preset heating method, collect the real-time slurry temperature after each heating cycle, update the reference boiling point temperature after each real-time slurry temperature collection, and perform the pulverizing and boiling operation after the boiling stage ends.
[0042] In one embodiment of this specification, after determining the reference boiling point, the overflow signal generated at the anti-overflow temperature is ignored. It should be noted that after the slurry is initially heated to the anti-overflow temperature, this temperature is slightly lower than the actual boiling point temperature; that is, the overflow signal triggered here is not a true overflow. After detecting the overflow signal, it is ignored for a short period, and the slurry is cyclically heated using a preset heating method to ensure that the slurry heats up uniformly and stably without overflowing during each heating process. The real-time slurry temperature is collected after each heating cycle, making the collected temperature closer to the true boiling point. The highest real-time slurry temperature is used as the current altitude boiling point temperature, making boiling point detection more accurate. It should be noted that the preset heating method may include specific heating power, heating time, etc., to ensure that the slurry heats up stably and uniformly during each heating cycle. The reference boiling point temperature is updated after each real-time slurry temperature is collected. Furthermore, after the boiling-holding stage, a pulverizing and boiling operation is performed.
[0043] In order to obtain an accurate boiling point temperature during the boiling stage, after determining the reference boiling point temperature, the previous anti-overflow signal is ignored, and the slurry is heated in a cyclic heating manner so that the slurry gradually approaches the boiling point during the heating process. The reference boiling point temperature is updated with the real-time slurry temperature collected after each heating cycle.
[0044] The slurry is circulated and heated using a preset heating method, specifically including: auxiliary heating of the slurry before each heating to raise the slurry temperature to a control point, wherein the control point is the reference boiling point temperature before the current heating.
[0045] In one embodiment of this specification, before each heating, the slurry is auxiliaryly heated using the reference boiling point temperature before the current heating as the temperature control point to raise the slurry temperature to the control point. For example, in the first heating process of a cycle, the slurry is heated at a preset heating power for a certain period of time using the initially determined reference boiling point temperature as the temperature control point to provide auxiliary heating and control the slurry temperature to approach the reference boiling point temperature. Similarly, in subsequent heating processes, the updated reference boiling point temperature before the current heating is used as the control point to provide auxiliary heating and control the slurry temperature to approach the updated reference boiling point temperature. For example, the auxiliary heating method here could be to use level 3 to heat the slurry at a constant temperature for 5 seconds before each heating process.
[0046] The preset heating method is to heat the slurry with a preset heating power for n seconds and then pause for m seconds until the preset first heating time corresponding to the current heating is met, and then the current heating ends.
[0047] In one embodiment of this specification, the preset heating method involves heating the slurry at a preset heating power for n seconds, then pausing for m seconds, performing intermittent small-cycle heating. The preset heating power is related to the heating power used in the auxiliary heating process, i.e., the constant-temperature heating. Generally, the preset heating power for intermittent small-cycle heating is higher than the heating power of the auxiliary heating process. For example, when the auxiliary heating power is level 3, the heating power for intermittent small-cycle heating can be set to a power greater than level 3, such as level 7 or level 8. During the cyclic heating of the slurry using the preset heating method, the standard for ending each heating cycle can be the heating duration of that cycle or the number of small-cycle heating cycles in the intermittent small-cycle heating.
[0048] When the heating cycle ends based on the heating duration of the current heating process, intermittent small-cycle heating continues until the preset first heating duration for that cycle is met. It should be noted that the first heating duration is an integer multiple of the sum of the heating duration (n seconds) and the stop duration (m seconds), and the difference between n and m is no greater than 3 seconds. For example, when heating for 8 seconds and stopping for 7 seconds, the first heating duration for that cycle can be an integer multiple of (8+7) seconds, such as 60 seconds. When the heating cycle ends based on the number of small-cycle heating cycles in the current heating process, a preset reference number of small-cycle heating cycles is set, for example, 4 times. The small-cycle heating cycle count is incremented by one after each n-second heating and m-second stop. The heating cycle ends when the total number of small-cycle heating cycles meets the reference number.
[0049] It should be noted that if the initial reference boiling point temperature, i.e., the reference boiling point temperature determined in step S101, is not greater than 92℃, then the first heating time in the first heating process of the cyclic heating process is doubled. Continuing with the example of 60 seconds in the previous case, the first heating time is doubled, with 120 seconds (60*2) serving as the first heating time for the first heating process. This prevents the boiling point from being too low due to false triggering of the anti-overflow signal during the first data acquisition. Doubling the heating time ensures that the temperature gradually returns to the actual boiling point, avoiding the impact of low pulp temperature on the pulping effect.
[0050] After each real-time slurry temperature is collected, the reference boiling point temperature is updated. Specifically, this includes: if the real-time slurry temperature collected in the previous heating is not greater than the reference boiling point temperature, the reference boiling point temperature is maintained after the previous heating ends, and the heating method of the previous heating is maintained in the subsequent heating; if the real-time slurry temperature collected in the previous heating is greater than the reference boiling point temperature, the reference boiling point temperature is replaced with the real-time slurry temperature collected in the previous heating ends, and the heating power is lower than that of the previous heating method in the subsequent heating.
[0051] In one embodiment of this specification, after the slurry is cyclically heated using a preset heating method, the real-time slurry temperature is collected during each heating process. If, among the multiple collected real-time slurry temperatures, the real-time slurry temperature from the previous heating process is not greater than the reference boiling point temperature, it indicates that no temperature higher than the reference boiling point temperature was collected, and the reference boiling point temperature is maintained. It should be noted that maintaining the reference boiling point temperature is also a form of updating, which can be understood as the temperature value being updated. In this case, it indicates that no temperature higher than the reference boiling point temperature was collected during the previous heating process, and the same heating method as the previous heating is maintained in subsequent heating processes, i.e., the heating method of the previous heating process remains unchanged. Conversely, if the real-time slurry temperature from the previous heating process is greater than the reference boiling point temperature, it indicates that a new boiling point temperature has appeared during the current heating process, and the reference boiling point temperature is updated using the real-time slurry temperature collected during the previous heating process. The updated reference boiling point temperature is the real-time slurry temperature collected during the previous heating process. Since a new boiling point temperature was obtained during the previous heating process, using the same heating method in subsequent heating processes would increase the risk of slurry overflow. Therefore, a power reduction approach is adopted, using a heating power lower than the previous heating method. The pure heating power is reduced during the cyclic heating process because pure heating does not involve temperature control. As the heating process progresses, the slurry temperature gets closer and closer to the actual boiling point. Reducing the heating power allows for a gradual approach to the actual boiling point with lower power, resulting in lower thermal inertia and reducing the likelihood of overflow.
[0052] In one embodiment of this specification, the overflow signal is ignored, and the slurry is circulated and heated using a preset heating method. If the circulation heating time corresponding to the circulation heating process meets a preset second preset time, the boiling stage ends. For example, the second preset time can be set to 300 seconds.
[0053] In addition to the above methods, the reference for ending the cyclic heating can also be determined by the number of cyclic heating cycles. After each cyclic heating process ends, if the real-time slurry temperature collected during the heating process is not greater than the reference boiling point temperature, the heating cycle count is performed. When the cumulative count meets the preset count threshold, the boiling stage ends. For example, the preset count threshold here can be 3 times.
[0054] During the boiling stage, a cyclic heating method is adopted. The reference boiling point temperature is updated based on the real-time slurry temperature collected each time. By cyclically heating, the slurry is gradually brought closer to the boiling point. After each heating, the real-time slurry temperature is collected to update the reference boiling point temperature. Compared with heating to the boiling point all at once, this method more accurately reflects the actual boiling point of the slurry and avoids the problem of a lower boiling point due to false triggering of the anti-overflow signal. Before each heating, the slurry is auxiliary heated to ensure that the slurry temperature is close to the reference boiling point temperature before the current heating. This helps the slurry to rise steadily during the heating process and reduces temperature fluctuations. An intermittent small-cycle heating method is adopted. By heating for n seconds and stopping for m seconds, the slurry is effectively heated while avoiding the risk of slurry overflow caused by continuous heating. The heating power is flexibly adjusted based on the comparison between the real-time slurry temperature and the reference boiling point temperature. When the real-time pulp temperature is not higher than the reference boiling point temperature, the heating method remains unchanged; when the real-time pulp temperature is higher than the reference boiling point temperature, the heating power is reduced to minimize the risk of overflow. For cases where the initially determined reference boiling point temperature is not higher than 92℃, a strategy of doubling the initial heating time is adopted, further improving the accuracy of boiling point measurement and avoiding subsequent heating problems caused by inaccurate initial measurements. Through preset parameters such as heating time and heating power, intelligent control of the heating process is achieved, reducing manual intervention, improving the automation level of the pulping process, ensuring that the pulp can fully react during heating, and improving pulping effect and product quality. Furthermore, the adjustment of circulating heating and heating power helps the components in the pulp to fully dissolve and mix, improving the uniformity and stability of the pulp.
[0055] Step S103: Use the latest reference boiling point temperature after the end of the boiling stage as the current altitude boiling point temperature.
[0056] In one embodiment of this specification, the latest reference boiling point temperature after the boiling-holding stage is used as the current altitude boiling point temperature. In the example above, the boiling-holding stage involves a total of 5 boiling point updates, processed using a specific waiting mode. During the waiting process, the NTC value is collected every 100ms, for a total of 66 values. The maximum and minimum values are obtained from these 66 values, then the 66 values are added together, and the maximum and minimum values are subtracted. The final value is divided by 64 to obtain the sampled boiling point. If it is the first time the boiling point is collected, the boiling point is recorded. If the boiling point obtained in subsequent collections is greater than the previous value, the boiling point is updated. By continuously sampling the NTC values, subtracting the maximum and minimum values, and then averaging, a more accurate boiling point value is obtained, avoiding data deviations caused by temperature fluctuations.
[0057] The above technical solution, viewed as a whole, involves finely crushing materials and mixing them with water until boiling. A boiling-holding stage is incorporated into the pulping process to obtain the boiling point temperature. This simplifies user operation, eliminating the need for additional boiling point detection procedures and the tedious step of boiling water, thus optimizing the user experience. Furthermore, boiling point detection can be achieved during pulping without the need for additional air pressure detection equipment, building upon existing products without incurring additional hardware costs. During the boiling stage, when the slurry is heated to the point that it triggers an overflow signal, the contact temperature is first detected. This utilizes the changes in the slurry's characteristics before overflow, providing an important reference for determining the baseline boiling point temperature. Combining the overflow signal and contact temperature detection results allows for a more accurate determination of the slurry's boiling point temperature. Relying solely on a temperature sensor for monitoring can lead to distorted temperature readings when the material becomes viscous and may coat the sensor, potentially triggering an overflow risk. Conversely, relying solely on the overflow detection mechanism can be misled by moisture or foam interference, resulting in inaccurate boiling point data. Therefore, combining overflow and temperature signal monitoring methods, which work synergistically, allows for a more accurate determination of the slurry's boiling point temperature. By comparing the contact temperature with a preset first temperature threshold, a more precise baseline value close to the actual boiling point can be determined. This calibration method based on actual phenomena is more adaptable to variations in material properties and environmental conditions compared to directly relying on a temperature sensor. After ignoring overflow signals, the food processor uses a preset heating method to circulate and heat the slurry. After each heating cycle, the corresponding real-time slurry temperature is collected. By continuously collecting and comparing the real-time slurry temperature with the current reference boiling point temperature, the reference boiling point temperature can be dynamically updated. This dynamic feedback mechanism allows for real-time updates to the reference boiling point temperature to adapt to changes in slurry properties, ensuring the continuous accuracy of the obtained boiling point temperature. After the boiling-holding stage, the food processor officially performs the pulverizing and cooking operation. Because the boiling point temperature has been accurately determined in the previous boiling-holding stage, the food processor can more precisely control the heating process, including heating temperature, heating time, and heating method. Precise control of the boiling point temperature improves slurry production efficiency. Accurate identification of the boiling point temperature avoids safety hazards such as slurry overflow or scorching due to excessive temperature, ensuring the safety and stability of the food processing process.
[0058] In one embodiment of this specification, a heating stage is provided before step S101, that is, before the boiling stage. In other words, the first stage of pulping is the heating stage. During the heating stage, an anti-overflow detection is activated to prevent the user from adding too much initial material or water. When the function is activated, the anti-overflow signal is detected immediately. If the material or water volume exceeds the upper limit, an alarm is directly triggered to remind the user.
[0059] During the heating phase, the slurry temperature should be controlled to reach the set temperature quickly. To achieve this, a full-power heating mode can be used at this stage. By monitoring the real-time slurry temperature, different temperature ranges are determined, and different heating strategies are employed within each range. For example, before reaching 40℃, full-power constant-temperature heating without stirring is used to ensure the slurry temperature in the entire liquid container stabilizes at 40℃. Heating is stopped when the temperature is above or equal to 40℃ and started when it is below 40℃. Within the temperature range of 40℃ to 80℃, an intermittent heating mode is used, i.e., heating for 30 seconds and stirring for 5 seconds. To ensure more accurate temperature measurement, this intermittent stirring method is employed, with temperature monitoring performed during stirring. Stirring causes the slurry to rotate, allowing the temperature to reach a balance, resulting in more accurate temperature readings. The final step in the heating phase is from 80℃ to 87℃. Heating to 87℃ is to accommodate the boiling point at an altitude of 2000 meters and to allow for a certain temperature margin to prevent overflow due to thermal inertia.
[0060] Before the boiling stage, the slurry is heated from a first temperature to a second temperature, and the heating time is recorded. Based on the heating time, the current production capacity is determined. Based on the current production capacity, the heating parameters and / or anti-overflow positions for the preset heating method during the boiling stage are determined. The heating parameters include heating power, which is positively correlated with the current production capacity.
[0061] In one embodiment of this specification, when the slurry is heated from a first temperature to a second temperature, the heating time corresponding to this temperature rise range is obtained. Generally, the first temperature can be 40°C, and the second temperature can be 80°C. Intermittent heating is used within the temperature range of 40°C to 80°C. Therefore, the heating time corresponding to this temperature rise range is the working time of the heating component. The slope of the slurry temperature rise is determined by the ratio of the temperature rise value within this temperature rise range to the working time of the heating component. The current production capacity is determined by referring to a pre-stored correspondence table based on the slope of the slurry temperature rise. It should be noted that the system pre-stores a correspondence table containing various rise slopes and the production capacity corresponding to each rise slope. Besides using the rise slope matching method, the correspondence between temperature change time and production capacity can also be pre-set in the system. By collecting the heating time of the heating component corresponding to the temperature rise from the first temperature to the second temperature, the actual temperature change time is determined, and the current production capacity corresponding to the current slurry preparation process is obtained by looking up the corresponding table. When determining the spill prevention position, a detection plate with electrodes is used. Each electrode corresponds to a different physical location, i.e., a different production capacity. Each electrode detects a corresponding spill prevention position; that is, each production capacity corresponds to a different spill prevention position. The current production capacity is used to match the corresponding spill prevention position. It should be noted that in this embodiment, the food processing machine used for matching spill prevention positions to different production capacities is as follows: Figure 2 , Figure 3 The food processing machine shown is based on air-to-air detection.
[0062] In one embodiment of this specification, the current production flow rate can be a capacity parameter, such as 800 ml, or a capacity level, such as high capacity, medium capacity, or low capacity. After determining the current production capacity, different production processes correspond to different production capacities. Here, we take capacity level as an example to explain the heating parameters for the boiling stage. For instance, the heating power of the first cycle heating in low capacity is set lower than the heating power of the first cycle heating in medium and high capacity. That is, the power starting point is different during the power reduction cycle in the cyclic heating process. The following are examples of heating parameters for the cyclic heating mode of the boiling stage under different production capacities provided in the embodiments of this specification:
[0063] During the cyclic heating process, assuming that the real-time pulp temperature collected each time is lower than the reference boiling point temperature corresponding to the current heating process, the cyclic heating mode under low capacity is as follows: The first cyclic heating uses level 3 constant temperature heating for 5 seconds (boiling point temperature control), followed by level 7 pure heating for 8 seconds, waiting for 7 seconds, and then repeats for 60 seconds before collecting the temperature of the first cyclic heating; The second cyclic heating uses level 3 constant temperature heating for 5 seconds (boiling point temperature control), followed by level 6 pure heating for 8 seconds, waiting for 7 seconds, and then repeats for 60 seconds before collecting the temperature of the second cyclic heating; The third cyclic heating uses level 3 constant temperature heating for 5 seconds (boiling point temperature control), followed by level 5 pure heating for 8 seconds, waiting for 7 seconds, and repeats for 210 seconds before collecting the temperature of the third cyclic heating; The fourth cyclic heating uses level 3 constant temperature heating for 5 seconds (boiling point temperature control), followed by level 4 pure heating for 5 seconds, waiting for 5 seconds, and repeats for 15 seconds before collecting the temperature of the fourth cyclic heating, and then the cyclic heating ends.
[0064] The circulating heating mode for medium capacity is as follows: The first circulating heating uses a constant temperature heating at level 3 for 5 seconds (boiling point temperature control), followed by a cycle of pure heating at level 8 for 6 seconds, then a wait of 9 seconds, for a total of 60 seconds before the first circulating heating temperature is collected; The second circulating heating uses a constant temperature heating at level 3 for 5 seconds (boiling point temperature control), followed by a cycle of pure heating at level 7 for 6 seconds, then a wait of 9 seconds, for a total of 60 seconds before the second circulating heating temperature is collected; The third circulating heating uses a constant temperature heating at level 3 for 5 seconds (boiling point temperature control), followed by a cycle of pure heating at level 6 for 5 seconds, then a wait of 5 seconds, for a total of 210 seconds before the third circulating heating temperature is collected; The fourth circulating heating uses a constant temperature heating at level 3 for 5 seconds (boiling point temperature control), followed by a cycle of pure heating at level 5 for 5 seconds, then a wait of 5 seconds, for a total of 15 seconds before the fourth circulating heating temperature is collected, and the circulating heating ends.
[0065] The high-capacity circulating heating mode is as follows: The first circulating heating uses level 3 constant temperature heating for 5 seconds (boiling point temperature control), followed by level 8 pure heating for 4 seconds, waiting for 6 seconds, and then the temperature of the first circulating heating is collected after 60 seconds; The second circulating heating uses level 3 constant temperature heating for 5 seconds (boiling point temperature control), followed by level 7 pure heating for 4 seconds, waiting for 6 seconds, and then the temperature of the second circulating heating is collected after 60 seconds; The third circulating heating uses level 3 constant temperature heating for 5 seconds (boiling point temperature control), followed by level 6 pure heating for 4 seconds, waiting for 6 seconds, and then the temperature of the third circulating heating is collected after 120 seconds; The fourth circulating heating uses level 3 constant temperature heating for 5 seconds (boiling point temperature control), followed by level 5 pure heating for 4 seconds, waiting for 6 seconds, and then the temperature of the fourth circulating heating is collected after 120 seconds, and then the circulating heating ends.
[0066] By employing the above technical solutions, different heating powers or waiting times can better accommodate pulping effects of varying capacities. Each cycle begins with constant-temperature heating for temperature control, followed by pure heating at a higher setting to bring the pulp temperature close to the boiling point. The waiting period aims to reduce thermal inertia and prevent overflow caused by excessive thermal inertia from continuous heating.
[0067] The pulping process in the food processing machine also includes a grinding and cooking stage. During this stage, the grinding and cooking operation includes a heating verification operation to check the boiling point temperature at the current altitude. In this heating verification operation, the pulp is heated using a preset verification heating method, ignoring overflow signals, and the real-time pulp temperature is acquired. When the real-time pulp temperature is higher than the boiling point temperature at the current altitude, the boiling point temperature at the current altitude is updated using the real-time pulp temperature.
[0068] In one embodiment of this specification, to ensure that the determined boiling point temperature matches the actual altitude boiling point when determining the current altitude boiling point temperature, a heating verification operation is included during the execution of the essential grinding and cooking process of the food processing machine to verify the current altitude boiling point temperature. The heating verification operation refers to heating the slurry using a preset heating method during the grinding and cooking stage, ignoring overflow signals, and collecting the real-time slurry temperature during this stage. The preset heating method here can be a three-level constant temperature heating method. To distinguish it from the real-time slurry temperature collected multiple times during the boiling stage in step S102, this can be called the real-time collected slurry temperature. The current altitude boiling point temperature is verified based on the relationship between the real-time slurry temperature and the latest reference boiling point temperature after the boiling stage ends. If the real-time collected slurry temperature obtained during the grinding and cooking stage is greater than the current altitude boiling point temperature, the current altitude boiling point temperature is updated using the real-time collected slurry temperature. By verifying the boiling point temperature at the current altitude during the crushing and cooking stage, the boiling point temperature at the current altitude can be determined more accurately. This avoids the limitation of updating the boiling point only during the boiling stage. The boiling point update process is carried out throughout the entire pulping process, which can ensure that the obtained boiling point temperature at the current altitude is closer to the actual boiling point.
[0069] In one embodiment of this specification, the initial grinding stage employs a rotation speed of 5000-8000 rpm, constant temperature heating at level 3, and a waiting period for three rounds. The constant temperature heating process uses the boiling point of the current altitude as the temperature control point. The low rotation speed in the initial grinding stage is for noise reduction, allowing the material to achieve a preliminary grinding effect. Constant temperature heating is used to prevent rapid temperature loss after low-to-medium volume stirring, and temperature compensation is achieved through constant temperature heating. High-speed grinding uses constant temperature heating at level 3, a waiting period, and a rotation speed of 9000-10000 rpm, cyclically executed for 10-15 minutes. Here, the constant temperature heating process uses a temperature one degree below the boiling point of the current altitude as the temperature control point. The increased rotation speed in high-speed grinding ensures the grinding effect. Boiling point temperature control is used for initial grinding because the low rotation speed leads to faster temperature loss. High-speed grinding uses boiling point -1 degree Celsius temperature control because prolonged high-speed stirring causes a slight rise in slurry temperature; to avoid complete boiling and foaming, the temperature needs to be controlled slightly below the boiling point to prevent overflow. Throughout the pulverization stage, if the slurry temperature is detected to be higher than the boiling point, the boiling point is updated based on the real-time slurry temperature collected, adjusting the boiling point according to the current altitude. It should be noted that the constant-temperature heating time is automatically adjustable. The heating time is dynamically adjusted based on the difference between the real-time slurry temperature and the boiling point. If the difference is greater than 2 degrees Celsius, the heating time is automatically increased by 5 seconds each time; if the difference is less than 2 degrees Celsius, the time is not adjusted.
[0070] In addition, during the boiling stage, a temperature one degree below the current altitude's boiling point is used as the temperature control point. A constant temperature heating setting (Level 1) is used, followed by pure heating at Level 4. After heating, the power is reduced to pure heating at Level 1, and a waiting period is observed, repeating this cycle for 4-6 minutes. The specific cycle duration can be set according to the different total boiling times based on the capacity. During the boiling process, if the real-time sampled pulp temperature is higher than the current altitude's boiling point, the current altitude's boiling point temperature is updated. The main purpose of the boiling stage is to enhance aroma and increase boiling effect. Constant temperature heating maintains the temperature, followed by short-term heating at medium power to achieve a simmering effect, and then low power heating to prevent rapid temperature loss. This process is repeated for 4-6 minutes depending on the three capacity levels (high, medium, and low). The heating time can also be dynamically adjusted. If constant temperature heating fails to reach the boiling point (-1 degree), the subsequent two pure heating cycles are each increased by 2 seconds, and the waiting time is reduced by 4 seconds to maintain the total time.
[0071] In one embodiment of this specification, the boiling point update during the pulverization or cooking stage is performed during a waiting step. Depending on the waiting time, a pulp temperature data point is collected every 100ms. After removing the maximum and minimum values, the average value is calculated, and this average temperature is used as the real-time pulp temperature. If the real-time pulp temperature is higher than the boiling point temperature at the current altitude, the boiling point temperature at the current altitude is updated. Both the pulverization and cooking stages have waiting steps. Updating during these waiting steps avoids temperature fluctuations during stirring and temperature rises during heating. By removing the maximum and minimum values and then averaging, the collected temperature becomes more accurate.
[0072] In one embodiment of this specification, when performing overflow detection, a conventional overflow probe method or an air-to-air overflow method can be used, mainly to detect the liquid level during the heating and boiling stages to prevent overflow.
[0073] In one embodiment of this specification, when performing temperature detection, a probe-type NTC can be used. By installing a probe-type NTC on the bottom or side wall of the cup, the probe structure is less affected by the material and heating plate, making the temperature measurement more accurate and further ensuring the accuracy of the collected temperature.
[0074] Through the above technical solution, the pulping process involves finely crushing materials and mixing them with water until boiling. Accurate boiling point identification during pulping not only simplifies user operation and eliminates the tedious step of additional boiling, but also significantly optimizes the user experience. Furthermore, continuously using the boiling point detection system throughout the entire pulping cycle effectively avoids the limitations of monitoring boiling point only during the holding-boil stage. Specifically, relying solely on temperature sensors (such as NTC) for monitoring can lead to distorted temperature readings when materials become viscous and may coat the sensor, potentially triggering an overflow risk. On the other hand, relying solely on the overflow detection mechanism can be misled by water vapor or foam interference, resulting in inaccurate boiling point data. Therefore, combining overflow and temperature signal monitoring methods, which complement each other, ensures data accuracy while further improving the precision of boiling point identification through continuous monitoring and real-time updates of boiling point data throughout the pulping process, providing users with a safer, more efficient, and reliable pulping experience.
