[0002] As living standards improve, consumers are increasingly demanding higher standards for the food safety, freshness, and taste of grains such as rice. Rice milling equipment, a common grain processing device in homes or small commercial settings, primarily functions to remove the husk from paddy rice and grind it into polished rice.

[0003] However, traditional rice milling equipment often lacks a real-time monitoring and feedback mechanism for the condition of paddy rice and finished rice during use, making it difficult for users to determine whether the grain has deteriorated, fermented, or been contaminated before consumption, posing a significant food safety hazard. Summary of the Invention

[0022] When there are at least two reference functional chambers, if the difference in the first odor result is greater than a first threshold, and the difference in each of the second odor results is less than the first threshold, then the detection result of the functional chamber is determined to be a material abnormality.

[0023] In one embodiment, the controller is further configured to:

[0064] 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.

[0065] It should be noted that the terms "first," "second," etc., used in this application can be used to describe various alarm prompts, but these alarm prompts are not limited by these terms. These terms are only used to distinguish between the first alarm prompt and the second alarm prompt. 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 solutions, or any combination of multiple solutions.

[0066] Traditional rice milling equipment (such as rice milling machines) lacks monitoring of the entire life cycle of grain, resulting in the following shortcomings: Lack of raw material detection, meaning it cannot identify early mold or fermentation in stored rice, leading to spoiled raw materials entering the processing stage and affecting food safety; Gap in process monitoring, as localized high temperatures and humidity during milling can easily cause secondary spoilage, and existing equipment lacks real-time gas monitoring methods, making it difficult to detect anomalies in a timely manner; Unclear finished product status, as rice grains in the receiving bin and user's rice box are prone to moisture absorption and odor, but existing technologies mostly rely on indirect judgment based on temperature and humidity, lacking direct odor perception and unable to accurately assess freshness and remaining shelf life; Limitations of single parameters, as relying solely on temperature and humidity data is prone to false alarms, and existing single-point sampling schemes have slow response and poor anti-interference capabilities, failing to meet the needs of high-precision monitoring. Therefore, there is an urgent need for a method for accurately identifying and providing early warning of the entire life cycle of grain in rice milling equipment.

[0067] Based on the above analysis, in one embodiment, such as Figure 1 As shown, this application provides a rice milling device. The rice milling device 10 includes: at least two functional chambers 101 arranged sequentially along the material conveying direction; odor conveying devices 102 respectively connected to each functional chamber 101; and gas sensors 103 respectively connected to each odor conveying device 102; and a controller 104 communicatively connected to the gas sensors 103.

[0068] Specifically, the gas sensor 103 is used to obtain odor data of the functional room by conveying the odor in the functional room through the odor conveying device 102; the controller 104 is used to determine the reference functional room associated with each functional room according to the material conveying direction; and to obtain the detection result of the functional room based on the odor data of the functional room and the odor data of the reference functional room.

[0069] In rice milling equipment, a functional chamber refers to the cavity space that undertakes the processing steps. The material conveying direction refers to the spatial flow of the material to be processed within the rice milling equipment, moving from one functional chamber to the next according to a pre-set processing sequence. For example, the functional chambers in a rice milling equipment include the rice inlet silo, rice milling silo, bran discharge silo, and rice receiving silo. The rice inlet silo is the storage cavity used to hold the material to be processed; it is the first station for the material entering the rice milling equipment. The rice milling silo is the functional chamber located downstream of the rice inlet silo, used to apply a grinding action to the material to remove its outer shell. The bran discharge silo is the functional chamber located downstream of the rice milling silo, used to receive the ground material and separate the detached outer shell from the main material, allowing the separated outer shell to exit the rice milling equipment and the main material to enter the rice receiving silo. The rice receiving silo is the functional chamber located downstream of the bran discharge silo, used to collect the main material obtained after separation in the bran discharge silo and to temporarily store the processed material.

[0070] For example, taking paddy rice as the material, the rice inlet is used to hold the paddy rice to be processed; the rice milling bin is used to apply a milling action to the paddy rice to remove the rice husk, so as to obtain a mixture of rice grains and rice husks; the husk discharge bin is set up to receive the mixture of rice grains and rice husks, and to separate the rice husks from the rice grains, so that the rice husks are discharged from the rice milling equipment and the rice grains enter the rice receiving bin; the rice receiving bin is used to collect and temporarily store the rice grains obtained after separation by the husk discharge bin.

[0071] Each functional room is equipped with an odor delivery device, and odor data refers to the detection data characterizing the odor conditions within the functional room. The controller is the electronic control unit in the rice milling equipment that performs logical operations and outputs control commands; it is the core component for achieving automated operation and intelligent monitoring of the rice milling equipment. For example, the controller is a microcontroller unit (MCU) located on the mainboard of the rice milling equipment.

[0072] Among them, the types of gas sensors may include, but are not limited to: metal oxide semiconductor (MOS) gas sensors, electrochemical gas sensors, infrared gas sensors, and thermal conductivity gas sensors.

[0073] In an optional embodiment, each gas sensor is connected to the controller via shielded twisted-pair cables. For example, the gas sensors are analog output MOS gas sensors, and the signal output terminals of each gas sensor are connected to different analog-to-digital converter (ADC) channels of the MCU. The MCU polls and collects the voltage values ​​of each channel at a certain frequency and converts them into odor detection results corresponding to each functional compartment; that is, the controller can obtain the odor detection results corresponding to the odor data of the functional compartment by processing the odor data transmitted by the gas sensors. Alternatively, the MCU can obtain the odor detection results corresponding to the odor data of the functional compartment by polling and collecting the voltage values ​​of each channel at a certain frequency and performing filtering processing.

[0074] Among these methods, the reference functional room associated with each functional room can be determined based on the material conveying direction, as exemplified below:

[0075] In an optional embodiment, reference functional rooms associated with each functional room are determined from among the functional rooms according to the material conveying direction. This includes: if the functional room is the first functional room in the material conveying direction, determining each functional room located after the functional room as a reference functional room associated with it. For example, if the functional room is the rice entering the silo, the corresponding reference functional rooms include the rice milling silo, the bran discharge silo, and the rice receiving silo.

[0076] In an optional embodiment, reference functional rooms associated with each functional room are determined from among the functional rooms according to the material conveying direction. This includes: if the functional room is the last functional room in the material conveying direction, determining the functional rooms preceding the functional room as reference functional rooms associated with it. For example, if the functional room is a rice receiving bin, the corresponding reference functional rooms include a rice entering bin, a rice milling bin, and a bran discharging bin.

[0077] In an optional embodiment, a reference functional room associated with each functional room is determined from among the functional rooms according to the material conveying direction. This includes: if the functional room is the last functional room in the material conveying direction, determining any functional room other than the first functional room that is located before the functional room as the reference functional room associated with it. For example, if the functional room is a rice receiving bin, the corresponding reference functional room is a rice milling bin or a bran discharging bin.

[0078] In an optional embodiment, a reference functional room associated with each functional room is determined from among the functional rooms according to the material conveying direction. This includes: if the functional room is any functional room other than the first and last functional rooms in the material conveying direction, then any functional room other than the first and last functional rooms and located before the functional room is determined as the reference functional room associated with the functional room. For example, if the functional room is a bran discharge bin, the corresponding reference functional rooms are the rice milling bin and the rice entering bin.

[0079] The test results can refer to the test results on the state of materials in the functional room, or to the test results on the processing environment of the functional room.

[0080] In the above embodiments, by installing odor conveying devices in each functional chamber arranged sequentially along the material conveying direction, and detecting the odor in each functional chamber through gas sensors connected to each odor conveying device, real-time monitoring of the odor status of each functional chamber during the entire rice milling process is achieved. This provides a data foundation for subsequent status monitoring and overcomes the technical deficiency of traditional rice milling equipment lacking real-time monitoring methods. The controller determines reference functional chambers associated with each functional chamber based on the material conveying direction, and comprehensively judges the odor data of each functional chamber and its reference functional chambers to obtain the detection results of each functional chamber. Therefore, the detection results of each functional chamber provide a more comprehensive and reliable basis for evaluating each functional chamber, effectively avoiding food safety hazards caused by a lack of monitoring methods, and significantly improving the intelligence level and material safety management capabilities of the rice milling equipment.

[0081] In one embodiment, the odor delivery device includes a delivery inlet, an odor transmission channel, and a first vent pipe connected in sequence. An odor transmission port is provided on the wall of the functional chamber. The delivery inlet is connected to the odor transmission port, and the outlet of the first vent pipe is connected to the inlet of the gas sensor.

[0082] In an optional embodiment, the first air guide tube may be made of polytetrafluoroethylene (PTFE) tubing or other types of tubing, and its inner diameter may be in the range of [0.3 mm, 1.5 mm].

[0083] Understandably, because PTFE material is hydrophobic and chemically inert, it can prevent gas adsorption and corrosion. Therefore, through the first gas guide tube, the gas in the functional room can be transmitted to the gas sensor without pollution and in its original state. This avoids the distortion of odor data caused by gas adsorption or chemical reaction in the pipeline during transmission, ensuring that the odor delivered by the odor delivery equipment can truly reflect the odor in the functional room, improving the accuracy of odor detection results, and further improving the accuracy of functional room status monitoring.

[0084] In an optional embodiment, the first gas guide tube can be sleeved onto the odor transmission channel. This achieves a sealed connection between the first gas guide tube and the odor transmission channel, ensuring that gas can smoothly flow from the odor transmission channel into the first gas guide tube and further be delivered to the gas sensor. Simultaneously, the sleeved connection method has the advantages of simple structure, convenient installation, and reliable connection, which helps simplify the assembly process of the odor delivery equipment, improve production efficiency, and maintain good airtightness and connection stability during long-term use.

[0085] In an optional embodiment, the diameter of the inlet is greater than or equal to that of the odor transmission port. This allows the gas exiting the odor transmission port to enter the inlet completely, preventing diffusion or dilution by outside air at the interface. This ensures that the gas sample delivered by the odor delivery device accurately reflects the functional chamber, thus improving the accuracy of odor detection results for the functional chamber.

[0086] In an optional embodiment, the air inlet and the odor transmission port are connected by a rubber sealing ring. This creates a sealed gas passage between the air inlet and the odor transmission port, preventing external air from mixing in at the connection point or gas from escaping from the functional room. This ensures that the gas sample delivered by the odor delivery device accurately reflects the functional room, providing accurate and reliable raw data for the controller.

[0087] In an optional embodiment, the odor delivery device further includes a fixing hole through which the odor delivery device is mounted on the outer wall of the functional chamber. For example, the fixing hole is secured to the outer wall of the functional chamber via a threaded interface or a snap-fit ​​structure. This achieves a stable installation of the odor delivery device on the outer wall of the functional chamber, preventing misalignment from affecting the alignment accuracy and sealing effect between the air inlet and the odor delivery outlet.

[0088] In an optional embodiment, the gas sensor is located outside the functional chamber. This avoids direct exposure of the gas sensor to the high temperature, high humidity, and high dust environment inside the functional chamber, preventing contamination, corrosion, or damage to the sensor's sensitive elements caused by temperature rises, moisture, or rice bran dust generated during rice milling. This extends the gas sensor's lifespan and ensures long-term stable detection performance. Furthermore, placing the gas sensor outside the functional chamber facilitates its installation, maintenance, calibration, and replacement. Maintenance can be performed without disassembling the functional chamber, reducing equipment maintenance difficulty and costs.

[0089] It is understandable that a large amount of fine dust (rice bran powder, rice husk fragments) is generated during the rice milling process. If the gas sensor is directly exposed inside the milling chamber, this dust can easily enter the micropores inside the sensor or cover the heating wire, leading to decreased sensor sensitivity, slower response, or even permanent damage. Using a PTFE hydrophobic and breathable membrane and a slender gas guide tube, solid particles can be effectively intercepted, allowing only gas molecules to pass through, significantly extending the sensor's lifespan. Furthermore, the rice milling chamber experiences high temperatures during processing, potentially accompanied by localized overheating. Gas sensors (such as MOS gas sensors) are temperature-sensitive; high temperatures can alter their baseline drift characteristics, affecting detection accuracy. Installing the sensor body in an area away from the heat source on the main control board and sampling through a thin tube with poor thermal conductivity avoids thermal shock to the sensor's core components, ensuring data stability. Moreover, if the gas sensor is installed in the functional chamber, replacement or calibration requires opening the chamber for disassembly, which is complex and easily compromises the seal. Since the gas sensor is fixed to the main board, maintenance does not require contact with the internal components; only the external filter membrane needs to be inspected or cleaned, greatly improving the maintainability of the equipment.

[0090] In the above embodiments, the odor delivery device forms a complete and closed gas flow path between the functional chamber and the gas sensor through the above structure. This allows the gas in the functional chamber to be smoothly and leak-free delivered to the gas sensor along the path, passing through the odor transmission port, the delivery inlet, the odor transmission channel, and the first gas guide pipe in sequence. This ensures the sealing and integrity of the odor delivery and avoids distortion of the detection results due to leakage or path interruption during the gas delivery process. It provides a structural basis for the gas sensor to obtain accurate odor data.

[0091] In one embodiment, the odor delivery device further includes at least one second air guide pipe disposed between the delivery inlet and the odor transmission channel. Thus, the second air guide pipe extends the gas delivery path from the functional chamber to the gas sensor, buffering and stabilizing the airflow during delivery, preventing fluctuations in the gas sensor detection value due to airflow pulsation or pressure changes, and improving the stability and consistency of the odor detection results.

[0092] In one embodiment, the odor delivery device further includes a filter layer; the air inlet is connected to the odor transmission port through the filter layer. Thus, by setting up the filter layer, solid particles (such as rice bran dust, impurities, etc.) in the gas can be intercepted, preventing them from entering the odor delivery device and the gas sensor. This avoids pipe blockage or contamination of sensor sensitive elements due to particle accumulation, which could affect detection accuracy and service life. Simultaneously, it ensures that the gas composition passes through the filter layer unaffected, improving the reliability of the delivered gas and the operational stability of the gas sensor.

[0093] For example, the filter layer is a hydrophobic and breathable membrane with a pore size of 0.22 micrometers ( This membrane allows volatile organic molecules such as ethanol and aldehydes to pass freely, while blocking rice grain dust, water droplets, and large particulate impurities from entering the conduit, thus protecting the gas sensor from contamination.

[0094] Taking rice milling equipment as an example, such as rice milling machine Figure 2 The diagram shows a schematic of a rice milling machine. The functional chambers of the rice milling machine are a rice inlet hopper 201, a rice milling hopper 202, a bran discharge hopper 203, and a rice receiving hopper 204. Through the division of labor and cooperation among these functional chambers, a complete material processing path is formed, from material input, milling, shell separation to finished product collection, achieving continuous and automated rice milling operations.

[0095] Taking the functional room as an example, such as the rice storage room Figure 3 The diagram shows the installation location of an odor conveying device in a rice inlet silo. The odor conveying device can be installed on the side wall of the rice inlet silo below the user feeding funnel to detect the freshness of newly added rice.

[0096] Taking the rice milling silo as an example, such as Figure 4 The diagram shows the installation location of an odor conveying device in a rice milling silo. The odor conveying device can be installed on the side wall of the rice milling and hulling chamber to detect odors generated during processing due to frictional heating or mold growth from residual impurities.

[0097] Taking the bran storage bin as an example, such as Figure 5 The diagram shows the installation location of an odor conveying device in a rice bran discharge bin. The odor conveying device can be installed near the rice bran outlet. Due to the large surface area and strong adsorption capacity of rice bran, the odor at this location can sensitively reflect the spoilage status inside the rice grains.

[0098] Taking the functional room as the rice receiving compartment as an example, such as Figure 6 The diagram illustrates the installation location of an odor conveying device in a rice receiving bin. The odor conveying device can be positioned above the rice receiving box or container from which the finished rice flows out, to monitor the storage status of the finished rice and whether it has been contaminated by external sources.

[0099] Therefore, by using odor transmission devices installed in each functional room, the odor of each functional room can be collected independently and without interference and transmitted to the corresponding gas sensor for detection, thereby obtaining the odor data of each functional room and providing a data basis for the controller to determine the status of each functional room.

[0100] like Figure 7The diagram shows a cross-sectional view of an odor delivery device. The odor delivery device includes a housing 1021, an air inlet (not shown), at least one second air guide pipe 1022, an odor delivery channel 1023, a first air guide pipe 1024, and a filter layer 1025. Specifically, the air inlet is connected to an odor delivery port on the wall of the functional chamber via the filter layer; the outlet of the first air guide pipe is connected to the inlet of a gas sensor; and the outlet of the first air guide pipe 1024 is connected to the inlet of a gas sensor 103. Thus, the air inlet, second air guide pipe, odor delivery channel, first air guide pipe, and filter layer are integrated into a single modular odor delivery device with filtering capabilities. This achieves both fixed relative positions and sealed connections between components, and removes solid particles through the filter layer before the gas enters the odor delivery channel, preventing dust contamination of the pipelines and gas sensor, and improving the operational stability and reliability of the odor delivery device.

[0101] exist Figure 7 Based on the diagram shown, as Figure 8 The diagram shows a schematic of an odor delivery device. The odor delivery device includes a fixing hole 1026, which secures the device to the outer wall of the functional chamber. This ensures the relative position and alignment accuracy between the air inlet and the odor delivery outlet, preventing sealing failure or gas leakage at the gas connection point due to loosening or displacement of the device. This ensures the positional stability of the odor delivery device and the reliability of the gas connection during operation.

[0102] In one embodiment, the controller is further configured to: acquire a first ambient odor detection result of a functional room and a second ambient odor detection result of a reference functional room; determine a first odor result difference based on the odor data of the functional room and the first ambient odor detection result; determine a second odor result difference based on the odor data of the reference functional room and the second ambient odor detection result; and obtain the detection result of the functional room based on the first odor result difference and the second odor result difference.

[0103] The first environmental odor detection result refers to the odor detection result detected in the functional room when the detection conditions are met, and is used as the odor status benchmark for the functional room. For example, when the functional room is idle, it is determined that the functional room meets the detection conditions, such as at 2:00 AM, when no new rice is entering the functional room and there is no processing activity; the detected odor result can be determined as the first environmental odor detection result. Alternatively, the functional room is determined to meet the detection conditions when the duration of the inactive processing step exceeds a set time threshold. Similarly, the second environmental odor detection result refers to the odor detection result detected in a reference functional room when the detection conditions are met.

[0104] Specifically, when the functional room meets the detection conditions, the odor in the functional room is transmitted to the corresponding gas sensor through an odor collection device connected to the functional room. The gas sensor then obtains the first ambient odor data of the functional room through the transmitted gas. The controller analyzes the first ambient odor data to obtain the first ambient odor detection result of the functional room. Similarly, a second ambient odor detection result for a reference functional room can be obtained.

[0105] In an optional embodiment, determining the first odor result difference based on the odor data of the functional room and the first environmental odor detection result includes: determining the difference between the odor detection result corresponding to the odor data of the functional room and the first environmental odor detection result as the first odor result difference.

[0106] Alternatively, the odor data from the functional room can be filtered to obtain first processed data; the first processed data can be analyzed to obtain the odor detection result of the functional room; the difference between the odor detection result of the functional room and the first environmental odor detection result is determined as the first odor result difference. Thus, by filtering the odor data from the functional room, the controller can remove high-frequency interference signals introduced by vibrations from the rice milling equipment, airflow pulsations, and sensor noise, enabling the first processed data to accurately reflect the slow changing trend of the odor state within the functional room. This avoids misjudgments caused by transient noise and helps improve the accuracy and reliability of the functional room detection results.

[0107] The filtering process can include moving average filtering, etc., to remove instantaneous noise.

[0108] In an optional embodiment, determining the second odor result difference based on the odor data of the reference functional room and the second environmental odor detection result includes: determining the difference between the odor detection result corresponding to the odor data of the reference functional room and the second environmental odor detection result as the second odor result difference.

[0109] Alternatively, the odor data from the reference functional room can be filtered to obtain second-processed data; this second-processed data can then be analyzed to obtain the odor detection results for the reference functional room; the difference between the odor detection results from the reference functional room and the second-environment odor detection results can be defined as the second odor result difference. Thus, by filtering the odor data from the reference functional room, it can be ensured that the reference functional room provides an accurate reference for the status monitoring of the functional room.

[0110] In the above embodiments, by calculating the difference between the real-time odor detection results of each functional room and their respective environmental odor detection results, the interference of environmental odors in the functional rooms on the odor detection results can be effectively eliminated. This ensures that the difference between the first odor result and the difference between the second odor result can truly reflect the change in the odor state within each functional room, improving the reliability and accuracy of the detection data. Furthermore, by comprehensively comparing the odor result differences of the functional rooms with the odor result differences of a reference functional room, compared to judging solely based on the absolute odor detection value or a single difference value of a single functional room, a more comprehensive reference basis can be provided for determining the detection results, further improving the reliability and accuracy of the detection results.

[0111] In one embodiment, the controller is further configured to: if the difference in the first odor result is greater than a first threshold and the difference in the second odor result is less than the first threshold, when the number of reference functional chambers is one, determine that the detection result of the functional chamber is a material abnormality.

[0112] The first threshold is a pre-set threshold, which can be set based on experience or obtained through experimental testing. In an optional embodiment, the first threshold corresponding to any functional compartment can be the same or different. That is, different functional compartments can flexibly configure different first thresholds according to their respective process characteristics, material properties, and environmental conditions to adapt to the differentiated detection needs of different functional compartments in the actual processing.

[0113] For example, the functional room is the rice milling silo, and the corresponding reference functional room is the rice entering silo. If the difference in the first odor result corresponding to the rice milling silo is greater than the first threshold, and the difference in the second odor result corresponding to the rice entering silo is less than the first threshold, the problem with the raw material itself can be ruled out. This indicates that there is old slag and mold in the rice milling silo during the processing, or that the grains are fermenting locally due to poor heat dissipation.

[0114] The controller is also used to: when there is only one reference functional room, if the difference in the first odor result is greater than a first threshold and the difference in the second odor result is greater than the first threshold, then determine that the detection result of the functional room is an abnormal cross-contamination.

[0115] For example, the functional room is the rice receiving compartment, and the corresponding reference functional room is the rice milling compartment or the bran discharge compartment. If the difference in the first odor result corresponding to the rice receiving compartment is greater than the first threshold, and the difference in the second odor result corresponding to the rice milling compartment or the bran discharge compartment is greater than the first threshold, it can be said that the pollution is continuous, that is, the freshly milled rice has already carried the moldy substances from the processing stage.

[0116] In the above embodiments, the controller can further classify the odor anomalies of the functional chamber into two types, "material anomalies" and "cross-contamination", based on whether the difference in the second odor result exceeds a first threshold under the single reference functional chamber architecture, thereby improving the precision of the detection results.

[0117] In one embodiment, the controller is further configured to: when there are at least two reference functional chambers, if the difference in the second odor result of the reference functional chamber located after the functional chamber is greater than a first threshold, and the difference in the first odor result is greater than the difference in the second odor result of the reference functional chamber located before the functional chamber, then determine that the detection result of the functional chamber is an abnormal processing environment.

[0118] For example, the functional room is the rice milling bin, and the corresponding reference functional rooms are the rice feeding bin and the bran discharge bin. If the difference in the first odor result corresponding to the rice milling bin is greater than the difference in the second odor result corresponding to the rice feeding bin, it indicates that the concentration of off-odors generated in the rice milling bin is significantly higher than that of the rice itself, suggesting that new substances (fermentation of accumulated residue or overheating) were generated during processing. If a high concentration of odor is detected in the bran discharge bin, that is, the difference in the second odor result corresponding to the bran discharge bin is greater than the first threshold, it can be used as cross-validation. Because rice bran has a large surface area, if the rice deteriorates inside, the bran will release volatile substances first. Therefore, when "the increase in the rice milling bin is significantly greater than that in the feeding bin" and "the bran discharge bin reaches the abnormal threshold", it is highly likely that it is due to the mold growth of old accumulated residue or thermal degradation of the grain caused by local high temperature, rather than simply a problem with new rice. In other words, if the difference in the second odor result corresponding to the bran discharge bin is greater than the first threshold, and the difference in the first odor result corresponding to the rice milling bin is greater than the difference in the second odor result corresponding to the rice entering bin, it can be said that there is old slag and mold in the rice milling bin, that is, the processing environment is abnormal, or the rice milling bin has local grain fermentation due to poor heat dissipation, that is, the material is abnormal.

[0119] The controller is also used to: when there are at least two reference functional chambers, if the difference in the first odor result is greater than a first threshold and the difference in each of the second odor results is less than the first threshold, then determine that the detection result of the functional chamber is a material abnormality.

[0120] For example, the functional room is the rice storage silo, and the corresponding reference functional rooms include the rice milling silo, the bran discharge silo, and the rice receiving silo. If the difference in the first odor result corresponding to the rice milling silo is greater than a first threshold, and the differences in the second odor results corresponding to the rice milling silo, the bran discharge silo, and the rice receiving silo are all less than the first threshold, it can be indicated that the newly stored rice has become damp or has undergone early fermentation. In other words, if the differences in the second odor results corresponding to each of the reference functional rooms located after the functional room are all less than the first threshold, and the differences in the first odor results corresponding to the functional room are greater than the first threshold, then the detection result of the functional room is determined to be an abnormality in the material.

[0121] For example, the functional room is the rice receiving compartment, and the corresponding reference functional rooms include the rice entering compartment, the rice milling compartment, and the bran discharging compartment. If the difference in the first odor result corresponding to the rice receiving compartment is greater than a first threshold, and the differences in the second odor results corresponding to the rice entering compartment, the rice milling compartment, and the bran discharging compartment are all less than the first threshold, it can be indicated that the finished rice has become damp or absorbed external odors during storage in the rice receiving compartment. In other words, if the differences in the second odor results corresponding to each reference functional room preceding the functional room are all less than the first threshold, and the differences in the first odor results corresponding to the functional room are greater than the first threshold, then the detection result of the functional room is determined to be an abnormality in the material.

[0122] In the above embodiments, the controller can further distinguish the odor abnormality of the functional chamber into two types, "processing environment abnormality" and "material abnormality", based on the abnormality of the upstream and downstream reference functional chambers in the multi-reference functional chamber architecture. This improves the precision of the detection results and enhances the intelligent monitoring level of the rice milling equipment.

[0123] In one embodiment, the controller is further configured to: determine a first alarm message and an alarm execution action matching the functional room when the detection result of the functional room indicates an anomaly; and output the first alarm message when executing the alarm execution action.

[0124] In an optional embodiment, a first alarm message and alarm execution action matching the functional room are determined based on a preset correspondence between the name of the functional room, the alarm message, and the alarm execution action.

[0125] In an optional embodiment, the first alarm notification is output via a display device or via the user terminal corresponding to the rice milling equipment. Thus, the first alarm notification can be presented intuitively to the user via the display device or user terminal, allowing the user to promptly obtain the detection results of the functional chambers in the rice milling equipment and take appropriate action based on the results. This avoids delays in handling anomalies due to the user's inability to know the status of the functional chambers, further ensuring food safety during the rice milling process.

[0126] Here, "display device" can refer to the display screen in rice milling equipment or other types of devices with display functions. "User terminal" refers to user-side electronic equipment.

[0127] Abnormal test results in functional rooms can indicate abnormalities in materials, processing environment, or cross-contamination.

[0128] For example, if the functional room is the rice silo, and an abnormality is detected in the rice silo, the first alarm message could be: "Raw materials are suspected of being spoiled; it is recommended to check the raw materials." The corresponding alarm action could be to control the yellow light in the rice milling equipment to flash.

[0129] For example, if the functional room is a rice milling silo, and an abnormal processing environment is detected in the rice milling silo, the corresponding first alarm message could be: "The rice milling silo needs cleaning; an odor from accumulated residue has been detected." The corresponding alarm action could be to control the red light in the rice milling equipment to flash slowly and to control the buzzer to sound briefly.

[0130] For example, if the functional room is a rice receiving compartment, and an abnormality is detected in the rice receiving compartment, the corresponding first alarm message could be: "The finished rice is damp; please consume it promptly or clean the user's container." The corresponding alarm action could be to keep the red light in the rice milling equipment constantly on and to make the buzzer sound a continuous alarm.

[0131] For example, if the functional compartment is a rice receiving compartment, and cross-contamination is detected in the rice receiving compartment, the corresponding first alarm message could be: "Discharge port closed. Cross-contamination may exist in the rice milling compartment before the rice receiving compartment. Please clean and try again." The corresponding alarm action could be to lock the discharge motor to prevent rice from flowing out and to prevent contaminated rice from entering the user's container.

[0132] In one embodiment, the controller is further configured to: generate a discharge lock command and a second alarm message if, for each functional chamber, the difference in the first odor result of a functional chamber is greater than a second threshold; lock the discharge motor in the rice milling equipment according to the discharge lock command, and output the second alarm message.

[0133] Among them, there is at least one functional room where the difference in the first odor result is greater than the second threshold. The second threshold is greater than the first threshold, and the second threshold is a preset threshold, which can be set based on experience or obtained from experimental testing.

[0134] In an optional embodiment, the second threshold corresponding to any functional compartment can be the same or different. That is, different functional compartments can be flexibly configured with different second thresholds according to their respective process characteristics, material properties and environmental conditions, so as to adapt to the differentiated detection needs of different functional compartments in the actual processing.

[0135] The second alarm message is used to indicate that the rice milling equipment is in a high-risk state. For example, the second alarm message could be: "Rice milling equipment malfunction, please stop the machine immediately for cleaning or contact after-sales service."

[0136] In one embodiment, for each functional room, the historical odor result differences of the functional room in the previous N historical moments before the current moment are obtained; if the first odor result difference of the functional room is greater than the differences of each historical odor result, and the differences of each historical odor result show an upward trend, then it is determined whether the first odor result difference of the functional room is greater than the second threshold.

[0137] Where N is greater than or equal to 3. It is understandable that if the difference in the first odor result of the functional chamber is greater than the difference in each historical odor result, and the difference in each historical odor result shows an upward trend, it indicates that the abnormal state of the functional chamber is continuously deteriorating. Therefore, by determining whether the difference in the first odor result of the functional chamber is greater than the second threshold, corresponding material discharge locking and alarm measures can be implemented in a timely manner when the current odor result difference reaches the second threshold, so as to improve the timeliness of response to high-risk states of rice milling equipment and the timeliness of safety intervention.

[0138] In the above embodiments, if the difference in the first odor result is greater than the second threshold, it indicates that the functional chamber in the rice milling equipment is in a high-risk state, which may be accompanied by severe mold or toxin release. Therefore, by generating a discharge lock command and a second alarm message, at the physical level, the discharge lock command prevents the rice milling equipment from continuing to discharge, thus preventing high-risk materials (such as severely moldy or toxin-containing materials) from entering the subsequent circulation or consumption stages. At the information level, the second alarm message informs the user that the functional chamber is in a high-risk state, reminding the user to take timely measures. In this way, the food safety of the rice milling process is protected in two dimensions: physical blocking and information prompting, thereby minimizing food safety risks.

[0139] Taking a rice milling machine with functional chambers including a paddy inlet, a rice milling chamber, a bran discharge chamber, and a rice receiving chamber as an example, Bc1 represents the odor detection result of the paddy inlet, and Bg1 represents the environmental odor detection result of the paddy inlet; Bc2 represents the odor detection result of the rice milling chamber, and Bg2 represents the environmental odor detection result of the rice milling chamber; Bc3 represents the odor detection result of the bran discharge chamber, and Bg3 represents the environmental odor detection result of the bran discharge chamber; Bc4 represents the odor detection result of the rice receiving chamber, and Bg4 represents the environmental odor detection result of the rice receiving chamber. Then, the odor difference in the paddy inlet is B1 = Bc1 - Bg1, the odor difference in the rice milling chamber is B2 = Bc2 - Bg2, the odor difference in the bran discharge chamber is B3 = Bc3 - Bg3, and the odor difference in the rice receiving chamber is B4 = Bc4 - Bg4. T1 represents the first threshold, and T2 represents the second threshold. Based on the above settings, as follows... Figure 9 The diagram shows a flowchart of a method for testing rice milling equipment, wherein:

[0140] S901, for each functional room, obtain the differences in historical odor results of the previous N historical times before the current time for each functional room.

[0141] S902, determine whether there is a difference in the first odor result of a functional room that is greater than the difference in each historical odor result, and whether the difference in each historical odor result shows an upward trend.

[0142] If it exists, then execute S903; otherwise, return to execute S901.

[0143] In S903, it is determined whether the difference of the first odor result of the functional chamber is greater than T2.

[0144] Wherein, if any Bi>T2 (i=1~4), it indicates that the rice milling equipment is in a high-risk state, which may be accompanied by severe mildew or toxin release, then S904 is executed, that is, the corresponding execution action is: forcibly locking the discharging motor, prohibiting rice from flowing out to prevent contaminated rice from being output; meanwhile, sending a highest-level alarm to the user, prompting "System fault, please stop the machine immediately for cleaning or contact after-sales service for processing". Otherwise, S905 is executed.

[0145] In S904, the discharging motor is forcibly locked, rice is prohibited from flowing out to prevent contaminated rice from being output; meanwhile, a highest-level alarm is sent to the user, prompting "Rice milling equipment fault, please stop the machine immediately for cleaning or contact after-sales service for processing".

[0146] In S905, it is determined whether B1>T1, and B2<T1, B3<T1, B4<T1.

[0147] Wherein, if B1>T1, and B2<T1, B3<T1, B4<T1, it is determined that the newly stored rice has absorbed moisture or undergone early fermentation, then S906 is executed, that is, the corresponding execution action is: controlling the indicator light to blink in yellow, and pushing a prompt on the display device or user terminal: "Raw material is suspected of deterioration, it is recommended to inspect the raw material". Otherwise, S907 is executed.

[0148] In S907, it is determined whether B2>T1 and B1<T1, or B3>T1 and B2>B1.

[0149] Wherein, if B2>T1 and B1<T1 (excluding the problem of the raw material itself), or B3>T1 and B2>B1, it is determined that aged accumulated residues in the rice milling chamber are moldy, or local grain fermentation occurs due to poor heat dissipation, then S908 is executed, that is, the corresponding execution action is: controlling the indicator light to blink slowly in red, making the buzzer beep shortly, and prompting on the screen: "The rice milling chamber needs to be cleaned, abnormal odor from accumulated residues is detected". Otherwise, S909 is executed.

[0150] In S909, it is determined whether B4>T1, and B1<T1, B2<T1, B3<T1.

[0151] Wherein, if B4>T1, and B1<T1, B2<T1, B3<T1, it is determined that the finished rice has absorbed moisture or absorbed external odor during storage in the rice receiving chamber, then S910 is executed, that is, the corresponding execution action is: controlling the indicator light to stay on in red, making the buzzer alarm with a long beep, and prompting on the screen: "The finished rice has absorbed moisture, please consume it in time or clean the container". Otherwise, S911 is executed.

[0152] In S911, it is determined whether B4>T1, and (B2>T1 or B3>T1).

[0153] If B4 > T1, and (B2 > T1 or B3 > T1), it indicates that while the finished product warehouse has an odor, the processing warehouse or the bran discharge warehouse also has an odor, indicating that the contamination is continuous. That is, the freshly milled rice already carries moldy substances from the processing stage, thus it is judged as an abnormal cross-contamination. In this case, S912 is executed, which means: immediately lock the discharge motor to prevent rice from flowing out, prevent contaminated rice from entering the user's container, and display the message "Discharge port closed, cross-contamination may exist in the rice milling warehouse, please clean and try again." Otherwise, the process ends.

[0154] In the above embodiments, real-time monitoring, trend prediction, anomaly location, cross-contamination identification, and graded response of the odor status of each functional chamber of the rice milling equipment are realized, which effectively solves the technical problems of traditional rice milling equipment lacking monitoring and feedback mechanisms, being unable to distinguish anomaly types, and being unable to actively block the output of problematic materials when risks occur, and significantly improves the food safety assurance capability and intelligence level of the rice milling equipment.

[0155] like Figure 10 The diagram illustrates a flowchart of a detection method for rice milling equipment. In this method, odor transmission devices are deployed in each functional chamber of the rice milling equipment (such as the rice inlet chamber, rice milling chamber, bran discharge chamber, and rice receiving chamber), and these devices are connected to corresponding gas sensors. This allows the controller to obtain odor data from each functional chamber. Based on this odor data, the controller can determine the status of each functional chamber and issue alarms. The content of the status determination and alarm notifications can be found in the preceding description.

[0156] In one embodiment, such as Figure 11 As shown, a method for detecting rice milling equipment is provided. Taking the application of this method to the controller of rice milling equipment as an example, the method includes the following steps:

[0157] S1102, acquire odor data for each of at least two functional chambers arranged sequentially along the material conveying direction in the rice milling equipment.

[0158] In an optional embodiment, the rice milling equipment includes: an odor delivery device connected to each functional chamber, and a gas sensor connected to each odor delivery device. The gas sensor is used to obtain odor data of the functional chambers by transmitting odors from the functional chambers through the odor delivery devices.

[0159] The structure of the odor delivery device can refer to the aforementioned content, or other forms of structure can be adopted, as long as it can achieve the purpose of delivering the odor in the functional room to the gas sensor.

[0160] S1104, for each functional room, determine the reference functional room associated with the functional room from each functional room according to the material conveying direction.

[0161] In an optional embodiment, reference functional rooms associated with each functional room are determined from among the functional rooms according to the material conveying direction. This includes: if the functional room is the first functional room in the material conveying direction, determining each functional room located after the functional room as a reference functional room associated with it. For example, if the functional room is the rice entering the silo, the corresponding reference functional rooms include the rice milling silo, the bran discharge silo, and the rice receiving silo.

[0162] In an optional embodiment, reference functional rooms associated with each functional room are determined from among the functional rooms according to the material conveying direction. This includes: if the functional room is the last functional room in the material conveying direction, determining the functional rooms preceding the functional room as reference functional rooms associated with it. For example, if the functional room is a rice receiving bin, the corresponding reference functional rooms include a rice entering bin, a rice milling bin, and a bran discharging bin.

[0163] In an optional embodiment, a reference functional room associated with each functional room is determined from among the functional rooms according to the material conveying direction. This includes: if the functional room is the last functional room in the material conveying direction, determining any functional room other than the first functional room that is located before the functional room as the reference functional room associated with it. For example, if the functional room is a rice receiving bin, the corresponding reference functional room is a rice milling bin or a bran discharging bin.

[0164] In an optional embodiment, a reference functional room associated with each functional room is determined from among the functional rooms according to the material conveying direction. This includes: if the functional room is any functional room other than the first and last functional rooms in the material conveying direction, then any functional room other than the first and last functional rooms and located before the functional room is determined as the reference functional room associated with the functional room. For example, if the functional room is a bran discharge bin, the corresponding reference functional rooms are the rice milling bin and the rice entering bin.

[0165] S1106. Based on the odor data of the functional room and the odor data of the reference functional room, the test results of the functional room are obtained.

[0166] In the above embodiments, by acquiring odor data from multiple functional chambers in the rice milling equipment, a comprehensive perception of the odor state at multiple stages of the entire rice milling process is achieved, overcoming the technical deficiency of traditional rice milling equipment lacking a real-time monitoring and feedback mechanism. Simultaneously, by introducing odor data from a reference functional chamber as a judgment benchmark, a comprehensive comparison of the functional chamber's own odor data with the reference functional chamber's odor data provides a more comprehensive and reliable basis for assessing the material state of each functional chamber. This effectively avoids judgment bias caused by the limitations of a single data source, improving the accuracy and reliability of the detection results. Therefore, by outputting the detection results of each functional chamber, this application enables users to promptly obtain the material state of each functional chamber in the rice milling equipment, promptly detect abnormalities during grain processing, and take corresponding measures. This effectively avoids the safety hazards of traditional rice milling equipment where users only discover grain spoilage when consuming the grain due to the lack of monitoring and feedback mechanisms, significantly improving the intelligence level of the rice milling equipment and the grain safety management capability.

[0167] In one embodiment, obtaining the detection result of a functional room based on odor data of the functional room and odor data of a reference functional room includes: acquiring a first environmental odor detection result of the functional room and a second environmental odor detection result of the reference functional room; determining a first odor result difference based on the odor data of the functional room and the first environmental odor detection result; determining a second odor result difference based on the odor data of the reference functional room and the second environmental odor detection result; and obtaining the detection result of the functional room based on the first odor result difference and the second odor result difference.

[0168] In one embodiment, obtaining the detection result of a functional chamber based on the difference between the first odor result and the difference between the second odor result includes: when the number of reference functional chambers is one, if the difference between the first odor result and the difference between the second odor result and the first threshold are greater than the first threshold, then the detection result of the functional chamber is determined to be a material abnormality.

[0169] In one embodiment, obtaining the detection result of a functional room based on the difference between the first odor result and the difference between the second odor result includes: if the number of reference functional rooms is one, and the difference between the first odor result and the difference between the second odor result are both greater than the first threshold, then the detection result of the functional room is determined to be an abnormal cross-contamination.

[0170] In one embodiment, obtaining the detection result of a functional room based on the difference in the first odor result and the difference in the second odor result includes: when there are at least two reference functional rooms, if the difference in the second odor result of a reference functional room located after the functional room is greater than a first threshold, and the difference in the first odor result is greater than the difference in the second odor result of a reference functional room located before the functional room, then the detection result of the functional room is determined to be an abnormal processing environment.

[0171] In one embodiment, obtaining the detection result of a functional chamber based on the difference between the first odor result and the difference between the second odor result includes: when there are at least two reference functional chambers, if the difference between the first odor result is greater than a first threshold and the differences between each second odor result are less than the first threshold, then the detection result of the functional chamber is determined to be a material abnormality.

[0172] In one embodiment, the method further includes: when the detection result of the functional room indicates an anomaly, determining a first alarm prompt message and an alarm execution action that match the functional room; and outputting the first alarm prompt message when executing the alarm execution action.

[0173] In one embodiment, the method further includes: for each functional chamber, if the difference in the first odor result of a functional chamber is greater than a second threshold, generating a discharge locking command and a second alarm message; locking the discharge motor in the rice milling equipment according to the discharge locking command, and outputting the second alarm message.

[0174] In one embodiment, the method further includes: for each functional room, obtaining the historical odor result differences of the functional room in the previous N historical times before the current time; if the first odor result difference of the functional room is greater than the differences of each historical odor result, and the differences of each historical odor result show an upward trend, then determining whether the first odor result difference of the functional room is greater than a second threshold.

[0175] In summary, such as Figure 12 As shown, a method for detecting rice milling equipment is provided. Taking the application of this method to the controller of rice milling equipment as an example, the method includes the following steps:

[0176] S1202, Obtain odor data for each of at least two functional chambers arranged sequentially along the material conveying direction in the rice milling equipment.

[0177] S1204, for each functional room, determine the reference functional room associated with the functional room from each functional room according to the material conveying direction.

[0178] S1206, Obtain the first environmental odor detection result of the functional room and the second environmental odor detection result of the reference functional room.

[0179] S1208, Based on the odor data of the functional room and the odor detection results of the first environment, determine the difference in the first odor results.

[0180] S1210, based on the odor data of the reference functional room and the odor detection results of the second environment, determine the difference in the second odor results.

[0181] S1212, based on the difference between the first odor result and the difference between the second odor result, the test results of the functional chamber are obtained.

[0182] S1214, If the detection results of the functional room indicate an abnormality, determine the first alarm prompt information and alarm execution action that match the functional room.

[0183] S1216, when performing an alarm execution action, output the first alarm prompt message.

[0184] The specific contents of S1202 to S1216 can be found in the aforementioned description.

[0185] As described above, this application achieves full coverage from raw material storage to finished product storage by installing odor conveying devices in each functional chamber of the rice milling equipment (such as the rice inlet, rice milling chamber, bran discharge chamber, and rice receiving chamber), and by using odor sensors to collect odor data from these functional chambers and aggregate it to the controller. This not only intercepts spoiled raw rice but also monitors heat and fermentation during processing, provides early warning of finished product storage contamination, and eliminates detection blind spots.

[0186] Specifically, the gas sensor is located on the main board of the rice milling equipment, and the air inlet of the odor delivery device is connected to the odor transmission port on the wall of the functional chamber through a filter layer. This design allows gas molecules to enter while blocking rice dust and moisture, solving the problems of sensor clogging and short lifespan in high-dust environments and ensuring long-term stable operation. Furthermore, by comparing the differences in odor results for each functional chamber with threshold values ​​using the controller, monitoring of each functional chamber is achieved. If only the rice silo is abnormal, it is determined that the raw material itself has deteriorated; if the rice milling silo shows a significant increase in temperature (while the rice intake is normal), it is determined that residual impurities in the silo are moldy or that there is localized heat fermentation; if only the rice receiving silo is abnormal, it is determined that the finished product is stored at a damp or contaminated temperature. Thus, the source of the problem can be located through odor distribution. In particular, it can distinguish between "new rice spoiled" and "old rice with mold," significantly reducing false alarms caused by changes in environmental humidity and allowing users to clearly identify the fault. Furthermore, by triggering different levels of alerts based on the degree of spoilage (e.g., a flashing yellow light suggesting inspection, a solid red light accompanied by a buzzer alarm), and displaying the specific location of the odor source on the screen, it transforms passive waiting into proactive notification. When severe spoilage is detected, it promptly reminds users to stop using the rice and clean the corresponding compartments (e.g., cleaning accumulated residue in the rice milling compartment) to prevent moldy rice from leaking out or being accidentally ingested, thus ensuring food safety.

[0187] In summary, this application achieves high-precision end-to-end monitoring at low cost, solving the pain points of traditional equipment being "invisible, unmanageable, and prone to misjudgment," and significantly improving food safety and user experience in both home and commercial settings. In other words, this application achieves low-cost, high-reliability end-to-end monitoring of grain, effectively solving the problem that traditional rice milling machines cannot detect the source of grain spoilage, and improving the level of food safety assurance.

[0188] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages in other steps. It is understood that the steps in different embodiments can be freely combined as needed, and all non-contradictory solutions formed by such combinations are within the scope of protection of this application.

[0189] Based on the same inventive concept, this application also provides a rice milling equipment testing device for implementing the rice milling equipment testing method described above. The solution provided by this device is similar to the solution described in the above method; therefore, the specific limitations in one or more embodiments of the rice milling equipment testing device provided below can be found in the limitations of the rice milling equipment testing method described above, and will not be repeated here.
