Description

Technical Field

[0001] The invention relates to the field of intelligent feed production, and in particular to a livestock feed production control method. Background Art

[0002] In modern animal husbandry, feed is an important material basis for livestock growth, development and production. High-quality feed can ensure that livestock obtain adequate nutrition and improve production performance and health level. However, it is not easy to produce high-quality livestock feed that meets various standards. On the one hand, the market has increasingly higher requirements for the quality and safety of livestock products, which requires strict control from the source of feed. The composition, nutritional value, and hygiene indicators of feed need to be precisely controlled to avoid livestock health problems caused by feed problems, which in turn affects the quality of the final livestock products. On the other hand, the feed production process involves many links, including raw material procurement, processing technology, storage conditions, etc. Problems in any link may affect the overall quality of the feed.

This solution uses a mixing box to mix the feed, drives the rotating shaft and the stirring blades through a driving motor, and extracts feed samples to a detection box for detection. This helps to timely grasp the quality status of the produced feed, so as to promptly discover problems and make adjustments, improve the controllability and scientificity of the production process, and prevent unqualified feed from entering the market.

[0005] Second, the program extracts feed samples into the test box for testing, but does not explicitly mention real-time quality testing during the production process, such as the specific parameters involved in conditioning, the moisture content and temperature of livestock feed, etc. This may lead to unstable quality of the products produced, failure to detect potential quality problems in a timely manner, and increase the probability of unqualified products.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1 and Figure 2 As shown, the present invention provides a livestock feed production control method, which includes the following steps: S1. Raw material detection: detecting the quality parameters of the livestock feed raw materials, the quality parameters including standard particle size specific gravity and moisture content.

[0039] The specific analysis method of the raw material detection is as follows: the first step is to prepare a sieve group according to the set particle size classification, recorded as each particle size sieve, and randomly select a part of the livestock feed raw material as a random inspection sample, recorded as the livestock feed raw material random inspection sample, and weigh the livestock feed raw material random inspection sample, recorded as , the sample of animal husbandry feed raw material is evenly spread on each particle size sieve for sieving, and the specific gravity of each particle size of animal husbandry feed raw material is obtained by weighing, which is recorded as , extract the preset standard particle size distribution range from the management database, screen out the proportion of the particle size of the livestock feed raw materials within the preset standard particle size distribution range from the particle size proportions of the livestock feed raw materials, and add them up to obtain the standard particle size proportion of the livestock feed raw materials, recorded as By setting the particle size classification and using the screen group, the particle size of livestock feed raw materials can be divided more accurately, which helps to ensure that the particle size of the feed raw materials meets the standard requirements, thereby ensuring the quality of the feed.

[0040] It should be noted that the specific analysis method for weighing the specific gravity of each particle size of the livestock feed raw material is: weigh the livestock feed raw material sample retained on the sieve of each particle size, and record it as the amount of livestock feed raw material of each particle size ,in Indicates The number of granularity, , Represents the number of granularities, through the formula Get the particle size ratio of livestock feed raw materials .

[0041] The second step is to put the sample of animal feed raw material into the oven, set the oven to a fixed temperature, and take several time points at the set time intervals to perform real-time detection of the weight of the sample of animal feed raw material at each time point when it is dried at a fixed temperature, and record it as the weight of the sample of animal feed raw material at the corresponding time point. , substituting it into the formula Get the weight difference of the livestock feed raw material sampling samples at two adjacent time points , Indicates The number of the time point, , select the minimum value from the weight difference of the livestock feed raw material sampling samples at two adjacent time points, record the time point corresponding to the minimum weight difference of the livestock feed raw material sampling samples at two adjacent time points as the drying time point of the livestock feed raw material sampling samples, and extract the weight corresponding to the drying time point of the livestock feed raw material sampling samples from the weight of the livestock feed raw material sampling samples at the corresponding time point, and record it as , through the formula Get the moisture content of livestock feed raw materials By real-time monitoring of weight changes at different time points at a fixed temperature, the moisture content of feed raw materials can be accurately calculated, providing reliable data for quality assessment. The appropriate moisture content has an important impact on the storage, use and nutritional value of feed.

[0042] S2. Raw material analysis: The quality evaluation coefficient of livestock feed raw materials is obtained based on the quality parameter analysis of livestock feed raw materials. .

[0043] The specific analysis method of the raw material analysis is: reading the standard particle size specific gravity of the livestock feed raw material , moisture content , substituting it into the formula Get the quality evaluation coefficient of livestock feed raw materials ,in They represent the weight factors of the set standard particle size specific gravity and moisture content respectively. Indicates the set standard moisture content; it is convenient to compare the quality differences of different batches of feed raw materials, which is conducive to screening high-quality products, and can detect quality problems in time and take corresponding measures to reduce potential risks and losses.

[0044] It should be noted that, in a specific embodiment, It can be set to 0.5. It can be set to 0.5. If the processing and use of feed have high requirements on particle size, such as certain specific feeding stages or animal species are very sensitive to feed particle size, then the weight of the standard particle size ratio may be relatively large, because the appropriate particle size helps animals digest and absorb and improves feed utilization, and the moisture content also has a great impact on feed storage, stability during processing, and nutritional components. If in a specific situation, the fluctuation of moisture content has a more significant impact on feed quality, the weights of the standard particle size ratio and moisture content are equal.

[0045] S3. Raw material preparation: Livestock feed is prepared according to the specific nutritional needs of livestock at a specific growth stage.

[0046] The specific analysis method for raw material allocation is as follows: the first step is to extract the specific nutritional needs of livestock at a specific growth stage from the management database, and at the same time read the nutritional components of various livestock feed raw materials; this can achieve precise feeding, allocate feed according to the actual needs of livestock, improve feeding efficiency and effects, help optimize feed formulas, reduce unnecessary waste of nutrients, reduce costs, better meet the nutritional needs of livestock at a specific growth stage, and promote their healthy growth and development.

[0047] The second step is to select appropriate feed raw materials from various types of livestock feed raw materials based on the specific nutritional needs of livestock at a specific growth stage, and determine the proportion of each feed raw material; this can ensure that livestock obtain the most suitable nutritional combination to meet their growth and production needs, and improve the health level and production performance of livestock.

[0048] The third step is to obtain the total amount of livestock feed required, weigh each feed raw material according to the proportion of each feed raw material, put the weighed raw materials into the mixing equipment, and obtain livestock feed by fully stirring and mixing; clarifying the total amount of feed required can accurately control the input and avoid waste or shortage. Weighing each raw material in proportion ensures the nutritional balance and targeting of the feed to meet the needs of livestock at specific stages. Putting the raw materials into the mixing equipment and fully stirring can make the various ingredients evenly distributed, so that the livestock can take in comprehensive nutrition in every bite, thereby improving the utilization rate and effect of the feed.

[0049] S4. Raw material crushing: Obtain the specific gravity of each particle size of the crushed livestock feed, analyze the crushing uniformity of the livestock feed, and determine whether the crushing uniformity is qualified.

[0050] The specific analysis method of the raw material crushing is: obtain livestock feed, put it into a crusher for crushing, record the crushed livestock feed as crushed livestock feed, analyze the crushed livestock feed according to the method of analyzing the specific gravity of each particle size of livestock feed, and obtain the specific gravity of each particle size of the crushed livestock feed, which is recorded as , Indicates the first The number of granularity, The average particle size ratio of the crushed livestock feed is obtained by taking the average value of each particle size ratio of the crushed livestock feed, which is recorded as , substituting it into the formula Get the uniformity of the crushing of livestock feed , It indicates the number of particle sizes of crushed livestock feed. The crushing uniformity of the livestock feed is compared with the preset crushing uniformity threshold. If the crushing uniformity of the livestock feed is less than the preset crushing uniformity threshold, it means that the crushing uniformity of the livestock feed is unqualified, and the livestock feed is crushed again. If the crushing uniformity of the livestock feed is greater than or equal to the preset crushing uniformity threshold, it means that the crushing uniformity of the livestock feed is qualified, and it is judged whether it needs to be tempered; crushing the livestock feed can increase the surface area of ​​the feed, which is beneficial to animal digestion and absorption and improves the feed utilization rate. By analyzing the specific gravity of each particle size, the crushing degree and uniformity of the feed can be accurately grasped to ensure the stable quality of each batch of feed.

[0051] S5. Tempering parameter detection: Detect the tempering parameters of livestock feed, including viscosity value and temperature.

[0052] The specific analysis method for the conditioning parameter detection is as follows: the first step is to extract a certain amount of the livestock feed as a conditioning test sample, which is recorded as the livestock feed sample, and the rotational viscometer is completely immersed in the livestock feed sample, and a fixed speed is set for the rotational viscometer, and each rotation time is divided according to the set time increment, and the rotational viscometer is started to measure in turn, and the viscosity value displayed by the rotational viscometer is recorded after each rotation time, which is recorded as the viscosity value of each rotation time of the livestock feed , Indicates The number of rotation durations, , substituting it into the formula Obtain the viscosity value of livestock feed , Indicates the number of rotation times; by using a rotational viscometer and setting a fixed rotation speed and dividing the time increment for measurement, the viscosity data at different rotation times can be obtained more accurately, and the viscosity characteristics of the feed can be fully understood.

[0053] The second step is to spread the livestock feed flat and divide it into several equal-sized areas. Insert the thermocouple probe into the center of each area of ​​the livestock feed and read its temperature, which is recorded as the temperature of each area of ​​the livestock feed. , Indicates The number of the region, , through the formula Get the temperature of livestock feed , Indicates the number of areas; spreading livestock feed flat and dividing it into areas for temperature measurement can provide a more comprehensive and accurate understanding of the overall temperature distribution of the feed, helping to ensure the consistency of feed temperature and avoid local overheating or overcooling.

[0054] Step 3: Read the moisture content of livestock feed raw materials , substituting it into the formula Get the modulation requirement coefficient of livestock feed , They respectively represent the set standard values ​​of viscosity, temperature, and moisture content; they can more accurately adjust and control the feed production process, improve production efficiency and effects, and ensure the nutritional intake and growth and development of animals in animal husbandry.

[0055] It should be noted that, in a specific embodiment, It can be set to 0.2. It can be set to 0.3. It can be set to 0.5. Generally speaking, moisture content may be more important because it has a more direct and critical impact on the storage stability, processing performance and nutritional components of feed. Suitable temperature is important for the preparation process of certain feeds (such as fermentation) and maintaining the quality of feed. The importance of viscosity value depends on the specific feed type and preparation purpose. If the viscosity of the feed has a greater impact on its subsequent use or processing, then its weight may be higher, otherwise it may be relatively low. Therefore, the weight corresponding to moisture content is higher.

[0056] S6. Conditioning parameter analysis: read the conditioning parameters of livestock feed, and combine the moisture content of livestock feed raw materials to obtain the conditioning requirement coefficient of livestock feed, and then determine whether conditioning is needed.

[0057] The specific analysis method of the conditioning parameter analysis is: comparing the modulation requirement coefficient of the livestock feed with the preset modulation requirement coefficient threshold value; if the modulation requirement coefficient of the livestock feed is greater than or equal to the preset modulation requirement coefficient threshold value, it means that the modulation requirement coefficient of the livestock feed is unqualified and the livestock feed needs to be tempered; if the modulation requirement coefficient of the livestock feed is less than the preset modulation requirement coefficient threshold value, it means that the modulation requirement coefficient of the livestock feed is qualified and the livestock feed is pelletized; this is conducive to maintaining the stability and consistency of feed production and ensuring the stability of the quality of the final product, thereby better meeting the needs of animal husbandry and providing reliable feed guarantee for the healthy growth of animals.

[0058] S7. Pellet testing: hardness of livestock feed pellets Conduct testing.

[0059] The specific analysis method of the granulation detection is as follows: obtaining the conditioned livestock feed, preparing it into granules, recorded as livestock feed granules, extracting a portion from the livestock feed granules as samples, recorded as livestock feed granule samples, obtaining livestock feed granule sample images, placing the livestock feed granule samples under a pressure device, applying pressure to the livestock feed granule samples in sequence according to set pressure levels, obtaining livestock feed granule sample images at each pressure level after a set time, and obtaining deformation degrees of the livestock feed granule samples at each pressure level by superimposing the livestock feed granule sample images with the livestock feed granule sample images at each pressure level, and sorting the deformation degrees of the livestock feed granule samples at each pressure level in order from small to large, and comparing them with preset deformation degree thresholds respectively, and recording the pressure level at which the deformation degree of the first livestock feed granule sample is greater than or equal to the preset deformation degree threshold as the maximum pressure level. , through the formula Get the hardness of livestock feed pellets , Indicates the preset reference pressure; by acquiring sample images and performing pressure testing and analysis, the deformation of feed particles under different pressures can be accurately understood, thereby evaluating its hardness and other characteristics, which helps to ensure that the produced livestock feed pellets have appropriate hardness and mechanical properties and maintain good stability during storage, transportation and use.

[0060] It should be noted that the specific analysis method of the deformation degree of the livestock feed pellet samples at each pressure level is: superimposing the livestock feed pellet sample image with the livestock feed pellet sample image at each pressure level, and obtaining the number of pixels overlapped between the livestock feed pellet sample image and the livestock feed pellet sample image at each pressure level, which is recorded as , Indicates The number of the pressure level, , Represents the number of pressure levels, and the total number of pixels of the livestock feed pellet sample image is extracted, recorded as , through the formula Obtain the deformation degree of livestock feed pellet samples under each pressure level .

[0061] S8. Cooling detection: obtain the thermal map of each temperature time point of each livestock feed pellet, and analyze the temperature uniformity of livestock feed cooling .

[0062] The specific analysis method of the cooling detection is: cooling the prepared livestock feed pellets, and selecting a number of livestock feed pellets therefrom, taking time points at fixed time intervals, recording them as temperature time points, scanning and imaging each livestock feed pellet at each temperature time point by an infrared thermal imager, generating a heat map of each temperature time point of each livestock feed pellet, and reading the chromaticity value of each pixel point in the heat map of each temperature time point of each livestock feed pellet, recording them as , Indicates The number of the livestock feed pellet heat map, , Indicates The number of each temperature time point, , Indicates The number of pixels, By taking the average value, we can get the average chromaticity value of each temperature and time of each livestock feed pellet thermal map, which is recorded as , substituting it into the formula Get the temperature uniformity of livestock feed cooling , Indicates the number of pixels. represents the number of temperature time points, Indicates the number of thermal maps of livestock feed pellets; generating thermal maps and analyzing color values ​​can provide a detailed understanding of the temperature distribution of each part of the feed pellets, thereby ensuring the uniformity of the cooling process, which is beneficial to ensuring the consistency of feed pellet quality and avoiding adverse effects on feed quality caused by local overheating or overcooling.

[0063] S9. Comprehensive analysis: Based on the quality evaluation coefficient of livestock feed raw materials, the hardness of livestock feed particles, and the uniformity of cooling temperature, the comprehensive evaluation index of livestock feed is obtained and feedback is provided.

[0064] See also Figure 3 As shown, the specific analysis method of the comprehensive analysis is: read the quality evaluation coefficients of livestock feed raw materials respectively , Hardness of livestock feed pellets , Temperature uniformity of livestock feed cooling , substituting it into the formula Get the comprehensive evaluation index of livestock feed , Represents the weight factor of the set quality evaluation coefficient, represents the weight factor of the set hardness, The weight factor representing the set temperature uniformity, It represents the hardness reference value set, and compares the comprehensive evaluation index of livestock feed with the preset comprehensive evaluation index threshold. If the comprehensive evaluation index of livestock feed is greater than or equal to the preset comprehensive evaluation index threshold, it means that the comprehensive evaluation index of livestock feed is qualified. If the comprehensive evaluation index of livestock feed is less than the preset comprehensive evaluation index threshold, it means that the comprehensive evaluation index of livestock feed is unqualified, and feedback is given to it. By comprehensively considering multiple factors such as the quality evaluation coefficient of feed raw materials, feed particle hardness and cooling temperature uniformity, the overall quality of livestock feed can be evaluated more comprehensively and objectively.

[0065] It should be noted that, in a specific embodiment, It can be set to 0.5. It can be set to 0.3. It can be set to 0.2. In the comprehensive evaluation index of livestock feed, the quality evaluation coefficient is usually more important because it is a comprehensive consideration of the overall quality of the feed, which may cover multiple important aspects. Although hardness is not as critical as the quality evaluation coefficient, it also has a certain influence. For example, for some situations that require a specific degree of chewing to promote digestion or meet the behavioral needs of animals, the suitability of hardness is more important. The importance of temperature uniformity requires specific analysis. If the temperature uniformity of the feed has a significant impact on the quality of the feed, microbial growth, etc. during production, storage or use, and thus affects the feeding and health of livestock, then its weight will increase accordingly. However, if in specific circumstances, temperature uniformity is not the main consideration and has little impact on the overall feed, then its weight may be smaller, so the weight corresponding to the quality evaluation coefficient is higher.

[0066] The present invention obtains a quality evaluation coefficient of a livestock feed raw material according to quality parameter analysis of the livestock feed raw material, obtains a modulation requirement coefficient of the livestock feed by reading the conditioning parameters of the livestock feed and analyzing the moisture content of the livestock feed raw material, and then determines whether conditioning is needed. The comprehensive evaluation index of the livestock feed is obtained according to the quality evaluation coefficient of the livestock feed raw material, the hardness of the livestock feed particles, and the temperature uniformity of cooling, and feedback is provided to the comprehensive evaluation index, thereby achieving comprehensive consideration and analysis of multiple key links and parameters in the livestock feed production process and ensuring a comprehensive evaluation of the feed quality.
