Description

Technical Field

[0001] The present invention relates to the field of harmless treatment, and particularly to a control method and a terminal for harmless treatment of diseased livestock and poultry. Background Art

[0002] Traditional methods for harmless treatment of livestock and poultry carcasses mostly adopt means such as high-temperature heating, incineration, and deep burial. Although these methods can effectively eliminate pathogenic microorganisms, there are many problems. First, it is difficult to monitor the heating time and temperature during the treatment process in real time, which easily leads to too long or insufficient heating time and cannot ensure the thoroughness of the treatment. Second, the traditional methods consume a large amount of energy and have high processing costs. Especially in the process of large-scale treatment, excessive heating not only wastes energy but also increases the economic burden. In addition, harmful gases or other pollutants may be released during the treatment process, further increasing the negative impact on the environment.

[0003] In order to address these problems, there are also some existing technical solutions that attempt to monitor the harmless treatment process, usually by controlling single parameters such as temperature and time to determine whether the treatment is completed. However, since a large amount of water evaporates during the treatment of livestock and poultry carcasses, single-parameter monitoring cannot accurately reflect the progress of the entire harmless treatment process, easily resulting in incomplete treatment or energy waste. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: to provide a control method and a terminal for harmless treatment of diseased livestock and poultry, and solve the problem that it is difficult to monitor the treatment situation of livestock and poultry carcasses.

[0022] Label Description:

[0023] 1. A control terminal for harmless treatment of diseased livestock and poultry; 2. Memory; 3. Processor. Detailed Embodiments

[0024] To describe the technical content, achieved objectives and effects of the present invention in detail, the following is described in conjunction with the embodiments and accompanied by the drawings.

[0025] Please refer to Figure 1 And Figure 2, a control method for harmless treatment of diseased livestock and poultry, comprising the steps:

[0026] S1. Measure the weight of the livestock and poultry carcasses to be treated;

[0027] S2. Put the livestock and poultry carcasses to be treated into a closed environment for heat treatment;

[0028] S3. Statistically analyze the mass of the steam generated in the closed environment, compare it with the weight of the livestock and poultry carcasses to be treated, and judge the degree of harmless treatment of the livestock and poultry carcasses based on the comparison result;

[0029] and / or,

[0030] Statistically analyze the humidity change rate in the closed environment, and judge the degree of harmless treatment of the livestock and poultry carcasses based on the humidity change rate.

[0031] It can be understood that the above method is executed in a closed environment with implementation conditions. This closed environment can be a heating chamber in a certain processing device or a certain closed processing space, which needs to be equipped with a heating function to heat the livestock and poultry carcasses to the harmless treatment temperature. At the same time, an exhaust pipe is provided in the closed environment to collect steam or dehumidify the space. Specifically, in order to monitor the degree of harmlessness in real time, at least a humidity sensor should be equipped in the above closed space to detect the humidity change in the closed space.

[0032] As can be seen from the above description, a control method for harmless treatment of diseased livestock and poultry is provided. The livestock and poultry carcasses are heated in a closed environment, and harmless treatment is achieved during the heating process. Since gasification occurs during the treatment of the livestock and poultry carcasses, in order to monitor the progress of harmless treatment, the livestock and poultry carcasses to be treated are weighed in advance, and the mass data of the steam generated during the treatment is collected. The degree of harmless treatment is judged based on the ratio of the steam mass data to the weight of the livestock and poultry carcasses; and / or, the humidity change rate in the closed environment is statistically analyzed, and the degree of harmless treatment is judged based on the humidity change rate, avoiding overheating and over-time heating in traditional treatment methods, realizing real-time monitoring of the harmless treatment process of diseased livestock and poultry carcasses, while reducing energy consumption and treatment costs.

[0033] In an embodiment of the present invention, step S3 specifically includes the steps:

[0034] Statistically analyze the mass of the steam generated in the closed environment, compare it with the weight of the livestock and poultry carcasses to be treated. If the corresponding ratio is greater than or equal to a preset threshold, it is considered that the harmless treatment is completed.

[0035] As can be seen from the above description, the total mass of steam discharged during the process can be calculated by time accumulation. Since the moisture content of livestock and poultry carcasses is about 60-70%, during the high-temperature sterilization process, the degraded part is basically discharged in the form of water vapor. The degraded mass of livestock and poultry carcasses can be obtained by the cumulative mass of steam discharged.

[0036] Preferably, during the heating process in a closed environment, the data of each sensor are transmitted to the central processing unit (MCU or PLC) of the electrical system. This unit calculates the cumulative mass of steam discharged according to the mathematical formula of steam cumulative mass and compares it with the initial mass of the livestock and poultry carcasses, and judges whether the sterilization process is completed according to the degradation rate value set by the electrical system.

[0037] Specifically, the steam mass is calculated by the following formula:

[0038] ;

[0039] In the formula, represents the steam mass (g); represents the pressure of water vapor gas in the pipeline (hPa); represents the absolute temperature (K); represents the cross-sectional area of the pipeline (m 2 ); represents the steam flow velocity (m / s); represents the sampling time interval (s); and respectively represent different moments, that is, the calculated value of the formula is the steam mass (g) in the time period from to .

[0040] In the embodiment of the present invention, step S3 specifically includes the steps of:

[0041] Statistical data of the absolute humidity in the closed environment, and calculate the humidity increment data in the closed environment per unit time. If the humidity increment data conforms to the preset law, it is considered that the harmless treatment is completed.

[0042] It can be understood that during the heating process of livestock and poultry carcasses, due to the continuous evaporation of the moisture in the carcasses, the humidity in the closed space presents different states during this process. According to empirical statistics, during the moisture discharge process in the closed space, the humidity increment first increases, then decreases until it becomes a certain negative value. If the humidity change rate presents this law, it is considered that the harmless treatment is completed.

[0043] In the embodiment of the present invention, step S3 specifically includes the steps of:

[0044] Statistically analyze the mass of the steam generated in the enclosed environment and compare it with the weight of the livestock and poultry carcasses to be treated. If the corresponding ratio is greater than or equal to the preset threshold, then statistically analyze the absolute humidity data in the enclosed environment, and calculate that the humidity increment data in the enclosed environment per unit time falls within the preset range, then it is considered that the harmless treatment is completed.

[0045] As can be seen from the above description, through the dual monitoring means of steam quality and humidity increment, the precise control of the harmless treatment process of diseased livestock and poultry is realized. Specifically, by statistically analyzing the mass of the steam generated in the enclosed environment and comparing it with the initial weight of the livestock and poultry carcasses, if the ratio reaches the preset threshold, then further monitor the absolute humidity data in the enclosed environment and calculate the humidity increment data per unit time. When the humidity increment data falls within the preset range, the system automatically determines that the harmless treatment is completed. By using the method of double verification, the accuracy of the harmlessness degree judgment is improved, and the risk of early destruction of the enclosed space environment and increased leakage of hazards due to misjudgment is avoided. The specific example is as follows: when the proportion of the collected steam mass is 60%-70% of the total weight of the treated carcasses, the humidity increment is statistically analyzed. At this stage, the humidity increment gradually decreases and finally falls into a negative value. If the humidity increment meets the preset range, it is considered that the harmless treatment is completed at this time.

[0046] A control terminal for the harmless treatment of diseased livestock and poultry includes a memory, a processor, and a computer program stored on the memory and executable on the processor. When the processor executes the computer program, the steps in a control method for the harmless treatment of diseased livestock and poultry are completed. That is, an execution terminal for a control method for the harmless treatment of diseased livestock and poultry is provided to execute the steps in the above method as a carrier.

[0047] The present invention provides a control method and terminal for the harmless treatment of diseased livestock and poultry, which are mainly applied to monitor the degree of harmless treatment of livestock and poultry carcasses. The following is a specific description in combination with embodiments.

[0048] Please refer to Figure 1 , the first embodiment of the present invention is:

[0049] A control method for the harmless treatment of diseased livestock and poultry includes the steps:

[0050] S1. Measure the weight of the livestock and poultry carcasses to be treated;

[0051] S2. Put the livestock and poultry carcasses to be treated into an enclosed environment for heat treatment;

[0052] S3. Statistically analyze the mass of the steam generated in the enclosed environment and compare it with the weight of the livestock and poultry carcasses to be treated. If the corresponding ratio is greater than or equal to the preset threshold, it is considered that the harmless treatment is completed.

[0053] That is, in this embodiment, the data of each sensor is transmitted to the central processing unit (MCU or PLC) of the electrical system, which calculates the cumulative mass of the discharged steam according to the mathematical formula of the cumulative mass of steam and compares it with the initial mass of the livestock and poultry carcasses, and determines whether the sterilization process is completed according to the degradation rate value set by the electrical system.

[0054] Specifically, the steam mass is calculated by the following formula:

[0055] ;

[0056] represents the steam mass (g); represents the water vapor gas pressure in the pipeline (hPa); represents the absolute temperature (K); represents the cross-sectional area of the pipeline (m 2 ) represents the steam flow velocity (m / s); represents the sampling time interval (s); and respectively represent different moments, that is, the calculated value of the formula is to the steam mass (g) in the time period. By obtaining the scene conditions of the closed environment, the steam mass generated in a certain time period is calculated.

[0057] The following table is the steam discharge mass table sampled and calculated every 0.5 seconds. The steam discharge mass column is the mass of the steam discharged every 0.5 seconds, and the total column is the total mass of the steam discharged within 0-5 seconds.

[0058]

[0059] Specifically, the harmless treatment is divided into two modes: sterilization and frying and drying. Sterilization mainly uses the degradation rate as an index, and its output is used as the raw material for organic fertilizer; frying and drying uses the evaporation of water as an index, and its output is oil and oil residue. According to multiple tests, the corresponding thresholds for different harmless treatments are as follows:

[0060] When the harmless treatment target is sterilization, step S3 is:

[0061] Statistically analyze the steam mass generated in the closed environment and compare it with the weight of the livestock and poultry carcasses to be treated. If the range of the corresponding ratio falls within 60%-70%, it is considered that the harmless treatment is completed.

[0062] When the harmless treatment target is frying and drying, step S3 is:

[0063] Statistically calculate the rate of change of the steam mass generated in the closed environment and compare it with the weight of the livestock and poultry carcasses to be processed. If the corresponding ratio is less than or equal to 0.5% and lasts for a preset duration, it is considered that the harmless treatment is completed.

[0064] Embodiment 2 of the present invention is as follows:

[0065] The difference from Embodiment 1 is that step S3 specifically includes the steps of:

[0066] Statistically calculate the absolute humidity data in the closed environment and calculate the humidity increment data in the closed environment per unit time. If the humidity increment data conforms to a preset rule, it is considered that the harmless treatment is completed.

[0067] That is, during the heat treatment of the livestock and poultry carcasses, due to the continuous evaporation of the moisture in the carcasses, different states of humidity change occur in the closed space. According to empirical statistics, during the moisture discharge process in the closed space, the humidity increment first increases, then decreases until it becomes a certain negative value. If the humidity change rate presents this rule, it is considered that the harmless treatment is completed.

[0068] Embodiment 3 of the present invention is as follows:

[0069] The difference from Embodiment 1 is that step S3 specifically includes the steps of:

[0070] Statistically calculate the steam mass generated in the closed environment and compare it with the weight of the livestock and poultry carcasses to be processed. If the corresponding ratio is greater than or equal to a preset threshold, then statistically calculate the absolute humidity data in the closed environment and calculate that the humidity increment data in the closed environment per unit time falls within a preset range, and it is considered that the harmless treatment is completed.

[0071] Specifically, by statistically calculating the steam mass generated in the closed environment and comparing it with the initial weight of the livestock and poultry carcasses, if this ratio reaches the preset threshold, then further monitor the absolute humidity data in the closed environment and calculate the humidity increment data per unit time. When the humidity increment data falls within the preset range, the system automatically determines that the harmless treatment is completed. In a double-verification manner, the accuracy of the harmlessness degree judgment is improved, and the risk of early destruction of the closed space environment and increased leakage of hazards due to misjudgment is avoided. The following is a specific example: when the collected steam mass accounts for 60%-70% of the total weight of the processed carcasses, the humidity increment is statistically calculated. At this stage, the humidity increment gradually decreases and finally falls into a negative value. If the humidity increment conforms to the preset range, it is considered that the harmless treatment is completed at this time.

[0072] Embodiment 4 of the present invention is as follows:

[0073] In any of the disease-free livestock and poultry harmless treatment control methods disclosed in Embodiments 1 to 3 above, it further includes step S0:

[0074] Keep the air pressure in the closed environment at a negative pressure state.

[0075] That is, under negative pressure conditions, when consuming the same amount of energy, the sterilization temperature becomes lower, the heating energy is reduced, and the time for harmless treatment can be shortened.

[0076] Specifically, the above method is executed by the following harmless treatment equipment. The equipment includes:

[0077] At least one closed chamber, and the closed chamber is provided with a heating component;

[0078] At least one negative pressure generator, which is used to communicate with the closed chamber and keep the chamber in a negative pressure state;

[0079] A sensor assembly, at least including a steam mass sensor and a humidity sensor. The sensor assembly is arranged in the communication pipeline between the negative pressure generator and the closed chamber. During the operation of the negative pressure generator, the sensor assembly is used to perform flow mass statistics and humidity measurement on the gas pumped out of the chamber.

[0080] Please refer to Figure 2 , Embodiment 5 of the present invention is:

[0081] A harmless treatment control terminal 1 for diseased livestock and poultry includes a memory 2, a processor 3, and a computer program stored on the memory 2 and executable on the processor 3. When the processor 3 executes the computer program, it completes the steps in any one of the above-mentioned harmless treatment control methods for diseased livestock and poultry in Embodiments 1 to 4.

[0082] In summary, the comprehensive beneficial effects of the present invention are as follows:

[0083] (1) Improve the accuracy of harmless treatment: The present invention realizes the precise control of the harmless treatment process of diseased livestock and poultry through the comprehensive monitoring of multiple indicators such as steam quality and humidity increment. Each embodiment adopts specific steam quality ratios and humidity change laws according to different treatment objectives (such as sterilization or frying and drying), ensuring the scientificity and reliability of the treatment process, avoiding incomplete treatment or misjudgment in traditional methods, and thus ensuring the effect of harmless treatment.

[0084] (2) Double verification to enhance safety: In some embodiments, the present invention adopts a double verification method of steam quality and humidity increment. After reaching the preset threshold of steam quality, the monitoring of humidity increment is further used to verify the treatment degree. This double judgment mechanism not only improves the accuracy of harmless treatment but also avoids the risk of prematurely opening the closed environment, prevents the leakage of harmful substances, and enhances the safety of the overall treatment process.

[0085] (3) Reduce energy consumption and lower costs: By monitoring the real-time changes in steam quality and humidity, the present invention can immediately stop heating after the processing is completed, avoiding energy waste caused by overheating. Meanwhile, in Example 4, by conducting the processing under a negative pressure state, the temperature required for the processing is effectively reduced, further reducing energy consumption. This energy-saving design not only improves the processing efficiency but also greatly reduces the operating costs.

[0086] (4) Flexible processing modes: The present invention supports different processing modes (such as sterilization and frying and drying), and different judgment thresholds are set according to different processing requirements. This flexibility enables the method to meet the harmless treatment requirements in different scenarios. It can not only use the output as organic fertilizer but also extract oil and oil residues, broadening the application scope of the treatment and enhancing the versatility of the equipment.

[0087] The above are only the embodiments of the present invention and do not limit the patent scope of the present invention accordingly.
