Description

Technical Field

[0001] The invention relates to the field of industrial automatic control, and in particular to a method, a device and a medium for controlling the moisture content of a finished feed product. Background Art

[0002] Feed is the main way for animals to obtain essential nutrients such as energy, protein, minerals and vitamins. As a key link in the modern agricultural industry chain, feed production is not only directly related to the healthy growth of livestock and poultry and the sustainable development of the breeding industry, but also has a profound impact on social economy, environmental protection and human health. In the feed production process, microwave or near-infrared moisture sensors can be used to detect changes in feed moisture content in a timely manner, thereby adjusting the control parameters of the pelletizer and cooler to optimize the pelletizing and cooling processes and improve feed product quality and production efficiency.

[0003] However, the current feed production process faces multiple challenges in actual operation. Its detection scope is limited to the feed raw materials and finished product stages, resulting in limited detection accuracy; the on-site operation process is cumbersome and complicated, which increases labor costs and time consumption; at the same time, frequent calibration requirements make it difficult to improve production efficiency and achieve precise moisture control, making it difficult to quickly and efficiently produce feed products that meet the standards. Summary of the invention

[0004] The present invention provides a method, device and medium for controlling moisture in a finished feed product, so as to solve the problem that it is difficult to accurately control production control elements in a feed production process, thereby quickly and effectively generating finished feed products.

[0005] mixing feed raw materials to obtain a first feed;

[0006] The first feed is modulated, granulated and cooled to obtain a second feed; wherein the granulation is achieved by changing the extrusion force of the first feed by a frequency converter;

[0007] According to the comparison result of the moisture content of the second feed and the first feed, the modulation moisture content and cooling time of the second feed are adjusted so that the moisture content of the second feed reaches a preset standard to obtain a finished feed product.

[0008] The present invention can effectively understand the moisture changes of feed during the production process by comparing the moisture content of the first feed obtained after mixing the feed raw materials and the second feed obtained after modulation and preliminary cooling. This fixed-point monitoring method is more efficient than the traditional frequent sampling and detection, and reduces the time delays and errors caused by sampling and detection. According to the comparison results of the moisture content of the second feed and the first feed, the present scheme can adaptively adjust the modulation moisture and cooling time of the second feed. This adjustment mechanism enables the moisture content of the feed to reach the preset standard more accurately, avoiding feed quality problems caused by improper moisture control. At the same time, adaptive adjustment also reduces the frequency of manual intervention, and reduces the errors and calibration requirements caused by manual operation. In addition, since the frequency converter can automatically adjust the extrusion force, it can ensure the stability and consistency of the granulation process, and can prevent the occurrence of main motor overload and equipment slippage during the granulation process. Faults such as equipment wear and damage are reduced, thereby reducing equipment maintenance costs and the frequency of component replacement.

[0009] Compared with the prior art, the present invention can accurately capture the moisture changes of the feed during the production process by comparing the moisture content of the first feed and the second feed. This comparison is carried out in real time during the production process, rather than by sampling or frequent sampling after the production is completed, thereby ensuring the accuracy and effectiveness of monitoring, and can accurately control the production control factors including moisture. Therefore, it can solve the problem of difficulty in accurately controlling the production control factors in the feed production process, thereby quickly and effectively generating finished feed products.

[0010] As a preferred embodiment, the first feed is modulated, granulated and cooled to obtain the second feed, specifically:

[0011] The first feed is modulated by a plurality of modulators so that the modulated feed reaches a target moisture value, and based on the frequency converter, the feed with different moisture content after modulation is automatically adapted to be granulated by changing the extrusion force to obtain a plurality of feed pellets; wherein the frequency converter is used to change the speed of the main motor of the pelletizer;

[0012] The plurality of feed particles are cooled to obtain the second feed.

[0013] The cooling process of this preferred solution helps to reduce the moisture content of feed pellets, so that they meet the requirements of safe storage, while reducing moisture loss during storage and transportation. In addition, the frequency converter can automatically adjust the speed of the pelletizer main motor according to the actual moisture content of the feed after conditioning, thereby changing the extrusion force; when the moisture content of the feed is high, the frequency converter can ensure that the feed can be smoothly pressed into pellets by changing the speed, thereby avoiding the problem of insufficient extrusion force and easy slippage of the pressure roller; when the moisture content of the feed is low, the frequency converter can optimize the extrusion force by adjusting the speed, further reducing the extrusion force and reducing the risk of overloading the pelletizer main motor.

[0014] As a preferred solution, the first feed is modulated by a plurality of modulators so that the modulated feed reaches the target moisture value, specifically:

[0015] The first feed is preliminarily modulated by a modulator of a feed pelleting measurement and control system to obtain a preliminarily modulated feed; wherein the feed pelleting measurement and control system is composed of a loss-in-weight feed mechanism, the modulator, a moisture sensor and a modulator steam system;

[0016] Detecting the moisture content of the preliminary prepared feed by the moisture sensor to obtain a moisture detection result;

[0017] The steam flow and steam pressure of the modulator steam system are controlled according to the moisture detection result, and the modulation time is controlled by the loss-in-weight feeding mechanism and the modulator, so that the temperature and humidity of the preliminary modulated feed reach the preset standards; wherein the modulator changes the modulation time by a frequency converter.

[0018] The weight-loss feeder of the preferred solution can accurately control the amount of feed fed to the modulator by real-time monitoring of changes in material weight, ensuring accurate feed ratios during the modulation process. By accurately controlling the moisture content of the feed, it can ensure that the feed maintains an appropriate humidity during the pelleting process, which helps to improve the quality and stability of the feed.

[0021] The moisture content of the first feed is detected by the moisture sensor to obtain a mixed moisture detection result, and the first feed is stored in the storage device.

[0022] The moisture sensor in this preferred solution can monitor the moisture content of the first feed in real time. Through precise moisture control, the stability and consistency of the feed in the subsequent pelleting process can be ensured, and feed quality problems caused by excessively high or low moisture can be avoided. Storing the mixed feed in a storage device can ensure that the feed maintains appropriate temperature and humidity conditions before pelleting.

[0023] As a preferred solution, according to the comparison result of the moisture content of the second feed and the first feed, the modulation moisture content and cooling time of the second feed are adjusted so that the moisture content of the second feed reaches a preset standard to obtain a finished feed product, specifically:

[0024] The moisture content of the second feed is detected by a moisture sensor of a feed cooling measurement and control system to obtain a cooling moisture detection result; wherein the feed cooling measurement and control system is composed of a cooler, a moisture sensor and a material level measurement and control device;

[0025] If the cooling moisture detection result is lower than the mixed moisture detection result, the modulation moisture of the second feed is adjusted, and the time for the cooler to cool the second feed is adjusted by the material level measurement and control device, so that the moisture of the second feed reaches a preset standard, and the finished feed is obtained;

[0026] If the cooling moisture detection result is higher than or equal to the mixed moisture detection result, the second feed is defined as the finished feed product.

[0027] In this preferred solution, by comparing the cooling moisture detection result with the mixed moisture detection result, the material level measurement and control equipment can adaptively adjust the cooling time of the cooler. If the cooling moisture detection result is lower than the mixed moisture detection result, the system will automatically adjust the cooling time to change the moisture content of the feed; if the cooling moisture detection result is higher than or equal to the mixed moisture detection result, no further adjustment is required, and the feed is directly defined as a finished feed product. This adaptive adjustment mechanism ensures precise control of feed moisture and avoids feed quality problems caused by excessively high or low moisture. This solution reduces the need for manual intervention through automated control and real-time monitoring of the feed cooling measurement and control system, thereby reducing errors and uncertainties, and avoiding the need to frequently calibrate feed moisture during feed processing and the inability to accurately control feed moisture.

[0065] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0066] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "several" means two or more.

[0067] A moisture control method for a finished feed product provided in an embodiment of the present application is mainly used in situations where it is necessary to accurately control production control factors including time, temperature, and moisture in the feed production process, so as to quickly and effectively generate finished feed products, reduce feed production losses, and improve the qualified rate of finished products.

[0068] Embodiment 1:

[0069] See also Figure 1 The embodiment of the present application provides a method for controlling moisture in a finished feed product, including S1 to S3, and the specific implementation steps are as follows:

[0070] S1. Mix feed raw materials to obtain a first feed.

[0071] Step S1 of the embodiment of the present application is specifically as follows:

[0072] Obtain feed raw materials; wherein, feed raw materials include livestock and poultry feed, aquatic feed, aquatic extruded feed, pet feed and other derivative feeds.

[0073] The feed raw materials are mixed by a feed mixer of the feed mixing and measuring control system to obtain a first feed; wherein the feed mixing and measuring control system is composed of a feed mixer, a moisture sensor, an elevator and a storage device, and the storage device can be selected from a granulation bin, a material distribution bin (drum) and a buffer bin and other equipment with material storage and mixing functions;

[0074] Detecting the moisture of the first feed by using a moisture sensor to obtain a mixed moisture detection result;

[0075] The first feed is input into and stored in the storage device through the elevator.

[0076] To apply the embodiments of this application, please refer to Figure 2 , Figure 2 1 is a structural diagram of a livestock and poultry feed mixing measurement and control system provided in an embodiment of the present application, indicating that in the first embodiment, the specific structure of the livestock and poultry feed mixing measurement and control system is taken as an example to specifically explain the feed mixing measurement and control system;

[0077] like Figure 2 As shown, the livestock and poultry feed mixing measurement and control system includes: 1.1 mixer, 1.2 elevator and auxiliary equipment, 1.3 pelletizing bin / feeding bin (drum) / buffer bin, 1.4 moisture sensor / humidity sensor (including 1.4.1~1.4.4);

[0078] The specific operation method is as follows: livestock and poultry raw materials enter the livestock and poultry feed mixer (1.1) for mixing, each batch of raw materials after the mixing process is completed is placed in a buffer hopper, the moisture / humidity of the mixed raw materials is collected through a moisture sensor / humidity sensor (1.4.1~1.4.4), and the raw materials after the moisture / humidity collection are input into a pelletizing bin / feeding bin (drum) / buffer bin (1.3) for storage through an elevator and auxiliary equipment (1.2).

[0079] It should be noted that in the first embodiment of the present application, a moisture sensor is used to flexibly detect the moisture content of the feed, and a humidity sensor can also be used to flexibly detect the humidity of the feed. In addition, the number of these sensors is very flexible and can be set to single or multiple according to actual needs; and these sensors are all online sensors that can detect the status of the device or system in real time and uninterruptedly.

[0080] In this embodiment S1, the moisture sensor can monitor the moisture content of the first feed in real time. Through precise moisture control, the stability and consistency of the feed in the subsequent pelleting process can be ensured, and feed quality problems caused by excessively high or low moisture can be avoided. The mixed feed is stored in the pelleting bin to ensure that the feed maintains appropriate temperature and humidity conditions before pelleting.

[0081] S2. Modulating, granulating and cooling the first feed to obtain a second feed; wherein the granulation is achieved by changing the extrusion pressure of the first feed by a frequency converter.

[0082] Step S2 of the embodiment of the present application includes S2.1 to S2.2, specifically:

[0083] S2.1. Inputting the first feed into the feed pelleting measurement and control system through the loss-in-weight weighing feeding mechanism of the feed pelleting measurement and control system; wherein the feed pelleting measurement and control system is composed of the loss-in-weight weighing feeding mechanism, the modulator, the moisture sensor and the modulator steam system;

[0084] Performing preliminary modulation processing on the first feed by a modulator of the feed pelleting measurement and control system to obtain a preliminary modulated feed;

[0085] The moisture content of the preliminarily prepared feed is detected by a moisture sensor to obtain a moisture detection result;

[0086] The steam flow and steam pressure of the modulator steam system are controlled according to the moisture detection result, and the modulation time is controlled by the loss-in-weight feeding mechanism and the modulator, so that the temperature and humidity of the preliminary modulated feed reach the preset standards; and based on the frequency converter, the feed with different moisture content after modulation is automatically adapted to be granulated by changing the extrusion force to obtain a transitional feed; wherein, the modulator changes the modulation time by controlling the configured frequency converter; and the frequency converter is used to change the speed of the main motor of the pelletizer, and the extrusion force is changed by changing the speed of the main motor of the pelletizer.

[0087] To apply the embodiments of this application, please refer to Figure 3 , Figure 3 1 is a structural diagram of a livestock and poultry feed pelleting measurement and control system provided in an embodiment of the present application, indicating that in the first embodiment, the specific structure of the livestock and poultry feed pelleting measurement and control system is taken as an example to specifically explain the feed pelleting measurement and control system;

[0088] like Figure 3 As shown, the livestock and poultry feed pelleting measurement and control system includes: 2.1 loss-in-weight feeder, 2.2 pelletizer (including modulator), 2.3 modulator steam system, 2.4 pelletizer modulator (including 2.4.1 to 2.4.4), 2.5 moisture sensor / humidity sensor (including 2.5.1 to 2.5.4);

[0089] The specific operation method is as follows: the first feed enters the pelletizer modulator (2.4.1~2.4.4) after passing through the loss-in-weight weighing feeding mechanism (2.1), and the moisture / humidity of the modulated raw materials is collected through the moisture sensor / humidity sensor (2.5.1~2.5.4); at the same time, the system controls the modulated steam flow and steam pressure according to the moisture / humidity of the raw materials modulated by each layer of modulators, in conjunction with the modulator-associated steam system (2.3), and changes the modulation time through the frequency converter configured by the modulator control, so as to achieve the goal of controlling the feed raw material modulation process.

[0090] The number of the granulator modulators can be flexibly configured, and can be one or more.

[0091] The loss-in-weight feeder mechanism of S2.1 of this embodiment can accurately control the amount of feed fed to the modulator by real-time monitoring of changes in material weight, ensuring accurate feed ratio during the modulation process. By accurately controlling the moisture content of the feed, it can ensure that the feed maintains an appropriate humidity during the pelleting process, which helps to improve the quality and stability of the feed. Through the integrated moisture sensor, steam system and loss-in-weight feeder mechanism, the system can achieve intelligent management of the feed modulation process to ensure the stability and consistency of feed quality;

[0092] Moreover, in the current feed production technology, if the moisture content of feed preparation is improperly controlled, two serious problems will be caused: first, when the moisture content of the raw material is too low, the required extrusion force will increase abnormally, which will easily cause the main motor of the pelletizer to bear too much load and overload; second, when the moisture content of the raw material is too high, the extrusion force will be relatively insufficient, which will cause the equipment to slip and the pelletizing operation cannot be carried out normally, and eventually the main motor of the pelletizer will be overloaded due to improper load. In this solution, the frequency converter can automatically adjust the speed of the main motor of the pelletizer according to the actual moisture content of the feed after preparation, thereby changing the extrusion force. This automatic adjustment ability enables the pelletizing process to flexibly respond to feeds with different moisture content, avoiding pelletizing failures caused by inappropriate moisture content; when the moisture content of the feed is high, the frequency converter can ensure that the feed can be smoothly pressed into pellets by changing the speed, thereby avoiding the problem of insufficient extrusion force and easy slipping of the roller; when the moisture content of the feed is low, the frequency converter can optimize the extrusion force by adjusting the speed, further reducing the extrusion force and reducing the risk of overloading the main motor of the pelletizer.

[0093] S2.2, the ring die is rotated, and the pressing roller is controlled to rotate under the action of friction force, and the transition feed is extruded and compressed by the two together to obtain a number of feed particles after granulation;

[0094] A plurality of feed particles are cooled by a cooler of the feed cooling measurement and control system to obtain a second feed.

[0095] The cooling process of S2.2 of this embodiment helps to reduce the moisture content of the feed pellets, so that they meet the requirements of safe storage, and reduce the moisture loss during storage and transportation. The pelletized feed pellets have regular shapes and uniform sizes, which are convenient for packaging and transportation, and can reduce the breakage rate and loss during transportation.

[0096] S3. According to the comparison result of the moisture content of the second feed and the first feed, the prepared moisture content and cooling time of the second feed are adjusted so that the moisture content of the second feed reaches a preset standard, thereby obtaining a finished feed product.

[0097] Step S3 of the embodiment of the present application is specifically as follows:

[0098] The second feed is stored in a finished product bin of a feed cooling and control system; wherein the feed cooling and control system is composed of a cooler, a moisture sensor, a material level measurement and control device, and a finished product bin;

[0099] The moisture content of the second feed is detected by a moisture sensor to obtain a cooling moisture detection result;

[0100] If the cooling moisture detection result is lower than the mixed moisture detection result, the material level measurement and control device is used to adjust the cooling time of the second feed by the cooler, and the modulated moisture of the second feed is adjusted so that the moisture of the second feed reaches the preset standard, thereby obtaining a finished feed product; among them, the material level measurement and control device can select "radar level meter / electric push rod + material level meter / electric push rod + inductive material level meter" and other devices that can monitor and control the position, height or state of the material;

[0101] If the cooling moisture detection result is higher than or equal to the mixed moisture detection result, the second feed is defined as a finished feed product.

[0102] To apply the embodiments of this application, please refer to Figure 4 , Figure 4 1 is a structural diagram of a livestock and poultry feed cooling measurement and control system provided in an embodiment of the present application, indicating that in the first embodiment, the livestock and poultry feed cooling measurement and control system is specifically described by taking the specific structure of the livestock and poultry feed cooling measurement and control system as an example;

[0103] like Figure 4 As shown, the livestock and poultry feed cooling measurement and control system includes: 3.1, cooler; 3.2, dust collector / sakron; 3.3, crusher; 3.4, elevator; 3.5, finished product warehouse; 3.6, moisture sensor / humidity sensor (including 3.6.1~3.6.2); 3.7, finished product grading screen; 3.8, radar level sensor / electric push rod + level sensor / electric push rod + inductive level sensor.

[0104] The specific operation mode is as follows: the conditioned transition feed is squeezed through a ring die and a pressure roller to obtain pelletized feed particles;

[0105] The pelletized feed pellets are fed into a cooler (3.1) for cooling;

[0106] The dust collector / sakron (3.2) removes a large amount of dust generated during the feed processing to ensure the purity of the feed and the health of the workers;

[0107] The cooled livestock and poultry feed particles enter the crusher (3.3), the elevator (3.4), the finished product bin (3.5), and the moisture sensor / humidity sensor (3.6.2) configured between the cooler (3.1) and the elevator (3.4); wherein the crusher (3.3) is used to crush granular or block feed raw materials into smaller particles to meet the livestock and poultry's needs for feed of different particle sizes; the elevator (3.4) is used to lift the material from a low place to a high finished product bin; the finished product bin (3.5) is used to store feed that has been processed by cooling, dust removal, crushing, etc., and a moisture sensor / humidity sensor (3.6) is configured in the finished product bin (3.5) to collect the moisture content of the finished feed;

[0108] The cooling moisture detection result collected by the moisture sensor / humidity sensor (3.6) in the finished product bin (3.5) is compared with the mixed moisture detection result obtained after the livestock and poultry raw materials are first mixed; according to the moisture comparison result, by changing the control parameters of the "(3.8.1) radar level meter or (3.8.2) electric push rod + level meter / electric push rod + inductive level meter" configured by the cooler (3.1), the cooling time of the feed particles is controlled to obtain the finished livestock and poultry feed;

[0109] The finished product grading screen (3.7) is used to screen out larger particles in the finished livestock and poultry feed, making the finished feed more uniform and fine.

[0110] In this embodiment S3, by comparing the cooling moisture detection result with the mixed moisture detection result, the material level measurement and control device can adaptively adjust the cooling time of the cooler. If the cooling moisture detection result is lower than the mixed moisture detection result, the system will automatically adjust the cooling time to change the moisture content of the feed; if the cooling moisture detection result is higher than or equal to the mixed moisture detection result, no further adjustment is required, and the feed is directly defined as a finished feed product. This adaptive adjustment mechanism ensures precise control of feed moisture and avoids feed quality problems caused by excessively high or low moisture. This solution reduces the need for manual intervention through automated control and real-time monitoring of the feed cooling measurement and control system, thereby reducing errors and uncertainties, and avoids the need to frequently check the feed moisture during feed processing and the problem of being unable to accurately control the feed moisture.

[0111] Overall, this embodiment has the following beneficial effects:

[0112] This application can effectively understand the moisture changes of feed during the production process by comparing the moisture content of the first feed obtained after mixing the feed raw materials and the second feed obtained after modulation and preliminary cooling. This fixed-point monitoring method is more efficient than the traditional frequent sampling and detection, and reduces the time delays and errors caused by sampling and detection. According to the comparison results of the moisture content of the second feed and the first feed, this solution can adaptively adjust the modulation moisture and cooling time of the second feed. This adjustment mechanism enables the moisture content of the feed to reach the preset standard more accurately, avoiding feed quality problems caused by improper moisture control. At the same time, adaptive adjustment also reduces the frequency of manual intervention and reduces the errors and calibration requirements caused by manual operation. In addition, since the frequency converter can automatically adjust the extrusion force, it can ensure the stability and consistency of the granulation process, and can prevent the occurrence of main motor overload and equipment slippage during the granulation process. Faults such as equipment wear and damage are reduced, thereby reducing equipment maintenance costs and the frequency of component replacement.

[0113] In summary, this application relies on the Internet of Things technology and edge computing technology. By targeting the key links in the feed process such as mixing / granulation / cooling, relevant online detection sensors and automatic control components are added, especially in the key links in the preparation process such as granulation / cooling. Through the Internet of Things technology, the three elements of time, temperature and moisture can be visualized and standardized. Through edge computing technology, the standardization, visualization and automation of the feed production process can be achieved, and effective and real-time detection and control of moisture in the feed production process can be realized.

[0116] Among them, the livestock and poultry feed mixing measurement and control system 10 is used to mix livestock and poultry raw materials to obtain the first feed;

[0117] The livestock and poultry feed pelleting measurement and control system 20 and the livestock and poultry feed cooling measurement and control system 30 are used to modulate, pelletize and cool the first feed to obtain the second feed; wherein the pelletizing is achieved by changing the extrusion force of the first feed by a frequency converter;

[0119] In one embodiment, the livestock and poultry feed mixing measurement and control system 10 is composed of a livestock and poultry feed mixer, a moisture sensor, an elevator and a storage device. The storage device can be selected from a pelletizing bin, a material distribution bin (drum) and a buffer bin, etc., which have material storage and mixing functions;

[0121] A moisture sensor is used to detect the moisture of the first feed and obtain a mixed moisture detection result;

[0122] The elevator is used for inputting the first feed into the storage device and storing it.

[0123] The storage device is used for storing the first feed.

[0124] To apply the embodiments of this application, please refer to Figure 2 , Figure 2 is a structural diagram of the livestock and poultry feed mixing measurement and control system provided in the embodiment of the present application, which shows the specific structure of the livestock and poultry feed mixing measurement and control system in the second embodiment of the present application;

[0125] like Figure 2 As shown, the livestock and poultry feed mixing measurement and control system includes: 1.1 mixer, 1.2 elevator and auxiliary equipment, 1.3 pelletizing bin / feeding bin (drum) / buffer bin, 1.4 moisture sensor / humidity sensor (including 1.4.1~1.4.4);

[0126] The specific operation method is as follows: livestock and poultry raw materials enter the livestock and poultry feed mixer (1.1) for mixing, each batch of raw materials after the mixing process is completed is placed in a buffer hopper, the moisture / humidity of the mixed raw materials is collected through a moisture sensor / humidity sensor (1.4.1~1.4.4), and the raw materials after the moisture / humidity collection are input into a pelletizing bin / feeding bin (drum) / buffer bin (1.3) for storage through an elevator and auxiliary equipment (1.2).

[0127] It should be noted that in the second embodiment of the present application, a moisture sensor is used to flexibly detect the moisture content of the feed, and a humidity sensor can also be used to flexibly detect the humidity of the feed. In addition, the number of these sensors is very flexible and can be set to single or multiple according to actual needs; and these sensors are all online sensors that can detect the status of the device or system in real time and uninterruptedly.

[0128] In the livestock and poultry feed mixing measurement and control system 10 of this embodiment, the moisture sensor can monitor the moisture content of the first feed in real time. Through accurate moisture control, the stability and consistency of the feed in the subsequent pelleting process can be ensured, and feed quality problems caused by excessively high or low moisture can be avoided. The mixed feed is stored in the pelleting bin to ensure that the feed maintains appropriate temperature and humidity conditions before pelleting.

[0129] In one embodiment, the livestock and poultry feed pelleting measurement and control system 20 is composed of a loss-in-weight feed mechanism, a modulator, a moisture sensor, a modulator steam system, and a frequency converter;

[0130] Among them, the weight-loss type feeding mechanism is used to input the first feed into the livestock and poultry feed pelleting measurement and control system;

[0131] A modulator, used for performing preliminary modulation processing on the first feed to obtain a preliminary modulated feed;

[0132] Moisture sensor, used to detect the moisture of the preliminary prepared feed and obtain the moisture detection result;

[0133] The modulator steam system, the weight-loss type feeding mechanism and the modulator are also used to control the steam flow and steam pressure according to the moisture detection result, and control the modulation time, so that the temperature and humidity of the preliminary modulated feed reach the preset standard to obtain the transition feed; wherein, the modulator changes the modulation time by controlling the configured frequency converter;

[0134] The frequency converter is used to automatically adapt to the feed with different moisture content after modulation by changing the extrusion pressure before obtaining the transition feed so as to granulate the preliminary modulated feed; and the frequency converter is used to change the speed of the main motor of the granulator, and the extrusion pressure is changed by changing the speed of the main motor of the granulator.

[0135] To apply the embodiments of this application, please refer to Figure 3 , Figure 3 is a structural diagram of the livestock and poultry feed pelleting measurement and control system provided in the embodiment of the present application, which shows the specific structure of the livestock and poultry feed pelleting measurement and control system in the second embodiment;

[0136] like Figure 3 As shown, the livestock and poultry feed pelleting measurement and control system includes: 2.1 loss-in-weight feeder, 2.2 pelletizer (including modulator), 2.3 modulator steam system, 2.4 pelletizer modulator (including 2.4.1 to 2.4.4), 2.5 moisture sensor / humidity sensor (including 2.5.1 to 2.5.4);

[0137] The specific operation method is as follows: the first feed enters the pelletizer modulator (2.4.1~2.4.4) after passing through the loss-in-weight weighing feeding mechanism (2.1), and the moisture / humidity of the modulated raw materials is collected through the moisture sensor / humidity sensor (2.5.1~2.5.4); at the same time, the system controls the modulated steam flow and steam pressure according to the moisture / humidity of the raw materials modulated by each layer of modulators, in conjunction with the modulator-associated steam system (2.3), and changes the modulation time through the frequency converter configured by the modulator control, so as to achieve the goal of controlling the feed raw material modulation process.

[0138] The number of the granulator modulators can be flexibly configured, and can be one or more.

[0139] The loss-in-weight feed mechanism of the livestock and poultry feed pelletizing measurement and control system 20 of this embodiment can accurately control the amount of feed fed to the modulator by real-time monitoring of changes in material weight, ensuring accurate feed ratio during the modulation process. By accurately controlling the moisture content of the feed, it can be ensured that the feed maintains appropriate humidity during the pelletizing process, which helps to improve the quality and stability of the feed. Through the integrated moisture sensor, steam system and loss-in-weight feed mechanism, the system can realize intelligent management of the feed modulation process and ensure the stability and consistency of feed quality;

[0140] Moreover, in the current feed production technology, if the moisture content of feed preparation is not properly controlled, two serious problems will be caused: First, when the moisture content of the raw material is too low, the required extrusion pressure will increase abnormally, which will easily cause the main motor of the pelletizer to bear too much load and overload; second, when the moisture content of the raw material is too high, the extrusion pressure will be relatively insufficient, which will cause the equipment to slip and the pelletizing operation to fail normally, and eventually the main motor of the pelletizer will be overloaded due to improper load. In this solution, the frequency converter can automatically adjust the speed of the main motor of the pelletizer according to the actual moisture content of the feed after preparation, thereby changing the extrusion pressure. This automatic adjustment capability enables the pelletizing process to flexibly respond to feeds with different moisture content, avoiding pelletizing failures caused by inappropriate moisture content; when the moisture content of the feed is high, the frequency converter can ensure that the feed can be smoothly pressed into pellets by changing the speed, thereby avoiding the problem of insufficient extrusion pressure and easy slippage of the roller; when the moisture content of the feed is low, the frequency converter can optimize the extrusion pressure by adjusting the speed, further reducing the extrusion pressure and reducing the risk of overloading the main motor of the pelletizer;

[0141] In addition, the cooling process helps reduce the moisture content of feed pellets to meet the requirements for safe storage, while reducing moisture loss during storage and transportation. The pelletized feed pellets are regular in shape and uniform in size, which is convenient for packaging and transportation, and can reduce the breakage rate and loss during transportation.

[0142] In one embodiment, the livestock and poultry feed cooling measurement and control system 30 is composed of a cooler, a moisture sensor, a material level measurement and control device, and a finished product bin;

[0143] The cooler is used to cool a plurality of feed particles to obtain a second feed; wherein the plurality of feed particles are obtained by rotating the ring die and controlling the pressing roller to rotate under the action of friction, and the two together perform extrusion and compression processing on the transition feed;

[0144] Finished product warehouse, used to store the second feed;

[0145] A moisture sensor is used to detect the moisture of the second feed and obtain a cooling moisture detection result;

[0146] The material level measurement and control equipment is used to adjust the modulated moisture of the second feed when the cooling moisture detection result is lower than the mixed moisture detection result, and adjust the cooling time of the second feed by the cooler so that the moisture of the second feed reaches the preset standard to obtain the finished livestock and poultry feed; among them, the material level measurement and control equipment can select "radar level meter / electric push rod + material level meter / electric push rod + inductive level meter" and other equipment that can monitor and control the position, height or state of the material;

[0147] Furthermore, if the cooling moisture detection result is lower than or equal to the mixed moisture detection result, the second feed is defined as a finished livestock and poultry feed product.

[0148] To apply the embodiments of this application, please refer to Figure 4 , Figure 4 is a structural diagram of the livestock and poultry feed cooling measurement and control system provided in the embodiment of the present application, which shows the specific structure of the livestock and poultry feed cooling measurement and control system in the second embodiment of the present application;

[0149] like Figure 4 As shown, the livestock and poultry feed cooling measurement and control system includes: 3.1, cooler; 3.2, dust collector / sakron; 3.3, crusher; 3.4, elevator; 3.5, finished product warehouse; 3.6, moisture sensor / humidity sensor (including 3.6.1~3.6.2); 3.7, finished product grading screen; 3.8, radar level sensor / electric push rod + level sensor / electric push rod + inductive level sensor.

[0150] The specific operation mode is as follows: the conditioned transition feed is squeezed through a ring die and a pressure roller to obtain pelletized feed particles;

[0151] The pelletized feed pellets are fed into a cooler (3.1) for cooling;

[0152] The dust collector / sakron (3.2) removes a large amount of dust generated during the feed processing to ensure the purity of the feed and the health of the workers;

[0153] The cooled livestock and poultry feed particles enter the crusher (3.3), the elevator (3.4), the finished product bin (3.5), and the moisture sensor / humidity sensor (3.6.2) configured between the cooler (3.1) and the elevator (3.4); wherein the crusher (3.3) is used to crush granular or block feed raw materials into smaller particles to meet the livestock and poultry's needs for feed of different particle sizes; the elevator (3.4) is used to lift the material from a low place to a high finished product bin; the finished product bin (3.5) is used to store feed that has been processed by cooling, dust removal, crushing, etc., and the finished product bin (3.5) is configured with a moisture sensor / humidity sensor (3.6.1) to collect the moisture content of the finished feed;

[0154] The cooling moisture detection result collected by the moisture sensor / humidity sensor (3.6.1) in the finished product bin (3.5) is compared with the mixed moisture detection result obtained after the livestock and poultry raw materials are first mixed; according to the moisture comparison result, by changing the control parameters of the "(3.8.1) radar level meter or (3.8.2) electric push rod + level meter / electric push rod + inductive level meter" configured by the cooler (3.1), the cooling time of the feed particles is controlled to obtain the finished livestock and poultry feed;

[0155] The finished product grading screen (3.7) is used to screen out larger particles in the finished livestock and poultry feed, making the finished feed more uniform and fine.

[0156] The livestock and poultry feed cooling measurement and control system 30 of this embodiment can adaptively adjust the cooling time of the cooler by comparing the cooling moisture detection result with the mixed moisture detection result. If the cooling moisture detection result is lower than the mixed moisture detection result, the system will automatically adjust the cooling time to change the moisture content of the feed; if the cooling moisture detection result is higher than or equal to the mixed moisture detection result, no further adjustment is required, and the feed is directly defined as a finished livestock and poultry feed product. This adaptive adjustment mechanism ensures precise control of feed moisture and avoids feed quality problems caused by excessively high or low moisture. This solution reduces the need for manual intervention through automated control and real-time monitoring of the livestock and poultry feed cooling measurement and control system, thereby reducing errors and uncertainties, and avoiding the need to frequently check feed moisture during feed processing and the problem of being unable to accurately control feed moisture.

[0157] Overall, this embodiment has the following beneficial effects:

[0158] This application can effectively understand the moisture changes of feed during the production process by comparing the moisture content of the first feed obtained after mixing livestock and poultry raw materials and the second feed obtained after modulation and preliminary cooling. This fixed-point monitoring method is more efficient than the traditional frequent sampling and detection, and reduces the time delays and errors caused by sampling and detection. According to the comparison results of the moisture content of the second feed and the first feed, this solution can adaptively adjust the modulation moisture and cooling time of the second feed. This adjustment mechanism enables the moisture content of the feed to reach the preset standard more accurately, avoiding feed quality problems caused by improper moisture control. At the same time, adaptive adjustment also reduces the frequency of manual intervention and reduces errors and calibration requirements caused by manual operation. In addition, since the frequency converter can automatically adjust the extrusion force, it can ensure the stability and consistency of the granulation process, and can prevent the occurrence of main motor overload and equipment slippage during the granulation process. Faults such as equipment wear and damage are reduced, thereby reducing equipment maintenance costs and the frequency of component replacement.

[0159] In summary, this application relies on the Internet of Things technology and edge computing technology, and adds relevant online detection sensors and automatic control components to the key links in the livestock and poultry feed process such as mixing / granulation / cooling, especially in the key links in the preparation process such as granulation / cooling. Through the Internet of Things technology, the three elements of time, temperature and moisture can be visualized and standardized, and the livestock and poultry feed production process can be standardized, visualized and automated through edge computing technology, realizing effective and real-time detection and control of moisture in the feed production process.
