Description

Technical Field

[0001] The present invention relates to the technical field of meat processing, and in particular to an acid removal device capable of reducing the loss of cattle and sheep carcasses through intelligent control. Background Art

[0002] my country's beef and mutton production primarily comes in the form of hot fresh meat, chilled fresh meat, and frozen meat. Currently, the latter two types of fresh meat dominate the market, and both require a stage of acid removal during production. Acid removal refers to the post-mortem rigor mortis (rigor mortis) and maturation of carcasses or meat cuts at 4°C. This process triggers a series of physiological and biochemical reactions, resulting in pH changes and changes in tenderness caused by protein degradation. While this production step can effectively improve meat quality, it also reduces weight during these physiological and biochemical reactions, severely impacting production efficiency.

[0003] The factors that affect the deacidification of beef and mutton are primarily the deacidification storage environment, including temperature, humidity, and airflow velocity. Excessively high temperatures accelerate the spoilage of beef and mutton, while excessively low temperatures inhibit the activity of endogenous enzyme systems in the muscle and prolong the deacidification process. Excessively high humidity accelerates microbial growth, while excessively low humidity leads to a significant loss of moisture in the meat, affecting its tenderness and other qualities, and increasing losses and a decrease in its economic value. Furthermore, excessive airflow velocity can cause significant evaporation of moisture from the surface of the meat, increasing losses. Therefore, controlling appropriate temperature, humidity, and airflow velocity plays an important role in maintaining beef and mutton quality and reducing deacidification losses, and is therefore of great value to companies in improving their production efficiency.

[0004] Currently, the ambient temperature and humidity in the acid drainage warehouse are mostly controlled by refrigeration fans and atomizing sprays. However, these systems cannot intelligently adjust temperature and humidity according to carcasses at different locations and sizes within the acid drainage warehouse, resulting in a decline in carcass quality and increased losses. Based on previous research results, the present invention addresses the current situation in which beef and mutton production enterprises share a single acid drainage warehouse for cattle and sheep carcass acid drainage. This avoids the problem of declining beef and mutton quality and increased losses caused by the inability to simultaneously meet the acid drainage environmental requirements of cattle and sheep carcasses of different sizes. By intelligently regulating the ambient temperature, humidity, and airflow velocity within the acid drainage warehouse according to the size of the cattle and sheep carcasses, the acid drainage quality of cattle and sheep carcasses at different locations within the acid drainage warehouse is maintained while reducing acid drainage losses. Summary of the Invention

[0005] The purpose of the present invention is to make up for the shortcomings of the existing technology and provide an acid removal device that reduces the loss of cattle and sheep carcasses while using intelligent control. The present invention collects information in all dimensions through a multi-dimensional perception module, combined with dynamic control by an intelligent control module, to control the carcass loss to 3.0%-5.5%, which is more than 20% lower than the traditional loss; the environmental control module is independently controlled in different partitions to adapt to different carcass requirements and ensure stable quality; the structural design is adapted to industrial production, reducing energy consumption and significantly improving efficiency.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: an acid-discharging device that can reduce the loss of cattle and sheep carcasses while being intelligently controlled, the acid-discharging device comprising:

[0007] Acid drainage warehouse, equipped with movable hanging rails for carrying cattle and sheep carcasses;

[0008] Environmental control module, including independently controlled micro-atomizing spray group, cooling fan group and independent air supply unit;

[0009] Multi-sensory module, including:

[0010] Distributed temperature and humidity sensors, including rack-embedded sensors and warehouse reference sensors;

[0011] Image recognition unit, the number of deployments satisfies the relationship: N 摄 =ceil(S 库 ×ρ / A), where S 库 is the area of ​​the acid drainage storage, ρ is the carcass hanging density, and A is the effective field of view of a single camera;

[0012] Weight monitoring unit, realized by strain sensor on the bearing seat of rail pulley;

[0013] Air velocity sensor;

[0014] The intelligent control module is communicatively connected to the environmental control module and the multi-sensing module, and includes:

[0015] a control unit configured to generate a temperature and humidity control curve based on a convolutional neural network;

[0016] a real-time feedback unit configured to dynamically modify environmental parameters based on weight loss;

[0017] The alarm unit is configured to trigger calibration when the weight loss at a point exceeds a dynamic threshold value, wherein the dynamic threshold value is determined based on the carcass type, the acid drainage stage and the initial pH value and ranges from 1.5% to 4.5%.

[0018] Furthermore, the independent air supply unit adopts an air bag structure to realize zoned air supply, and the atomizing nozzles of the micro atomizing spray group are distributedly installed on the hanging rod at a spacing of 6 hooks, and the nozzle spacing D = 6-0.2×(V 气 -0.5), where V 气 To monitor the air flow velocity (m / s) in real time.

[0019] Furthermore, the image recognition unit includes a top-mounted wide-angle camera, a column-mounted panoramic camera, and a laser scanning unit, and is configured to perform:

[0020] Carcass type is determined through bone feature extraction and contour convex hull analysis, with feature deviation allowed to be ≤15%, and dynamically corrected through a staged verification mechanism of a convolutional neural network;

[0021] The carcass is fitted into a tetrahedron based on the laser ranging data, and the carcass volume is calculated according to the volume formula:

[0022]

[0023] Among them, V1, V2, V3 and V4 are the coordinates of the tetrahedron vertices, N 分 is the number of tetrahedrons to be split.

[0024] Furthermore, the deployment of the air flow velocity sensor satisfies:

[0025] Every 4 hooks are equipped with a hot film anemometer;

[0026] Each conveying line is equipped with two differential pressure array probes.

[0027] Furthermore, the optimal temperature and humidity range output by the control unit is defined by the functional relationship:

[0028] T opt =T base +ΔT·f(species,volume)

[0029] H opt =H base +ΔH·f(species,volume)

[0030] Where: T base , H base is the species benchmark temperature and humidity, ΔT and ΔH are the temperature and humidity adjustment spans, and f(·) is the feature fusion operator based on the RELU activation function.

[0031] Furthermore, the correction algorithm of the real-time feedback unit is:

[0032]

[0033] Where: ΔW is the difference between the current weight loss and the target loss, k T ,k H ,k v is the loss proportional coefficient, c T , c H is the time-varying accumulation coefficient, S 体 is the carcass surface area.

[0034] Furthermore, when the alarm unit is triggered, the following steps are executed:

[0035] Freeze the current environmental control parameters;

[0036] Generate intervention instructions containing the coordinates of abnormal points;

[0037] Record historical environmental data for parameter calibration.

[0038] Furthermore, the real-time feedback unit performs feedback calibration every 3 hours, and the airflow speed setting value v set and carcass surface area S 体 Inversely correlated.

[0039] Furthermore, the hanging rail load-bearing structure is integrated with a strain sensor component, and the cooling fans of the refrigeration air unit are unevenly distributed according to the acid discharge storage area.

[0040] Furthermore, the deployment density of the distributed temperature and humidity sensors on the hanging rack is positively correlated with the carcass hanging density, and the wind speed adjustment accuracy of the independent air supply unit is ±0.1m / s.

[0041] Compared with the existing technology, the acid removal device that reduces cattle and sheep carcass losses through intelligent control has the following beneficial effects:

[0042] 1. This invention achieves full-dimensional information collection through a multi-sensing module: Distributed temperature and humidity sensors (deployed in direct correlation with hanging density) capture the carcass surface microenvironment and the warehouse's global benchmark at close range. An image recognition unit accurately identifies carcass type (feature deviation ≤ 15%) and calculates volume by fitting a tetrahedron. A weight monitoring unit tracks losses in real time. Airflow velocity sensors (one hot-film anemometer for every four hanging hooks and two differential pressure probes for each conveyor line) accurately acquire local wind speed. Combined with the intelligent control module's convolutional neural network temperature and humidity curve model and a real-time feedback correction algorithm (calibrated every three hours, with wind speed inversely correlated with carcass surface area), this system dynamically matches the optimal acid-draining environment for carcasses of different types and sizes, strictly controlling weight loss within a dynamic threshold of 3.0%-5.5%. This reduces losses by over 20% compared to traditional acid-draining devices, significantly improving the company's economic benefits.

[0043] 2. The present invention utilizes an environmental control module with a partitioned independent control design: the micro-atomizing spray group is distributedly installed according to the hook spacing, and the nozzle spacing is dynamically adjusted with the air flow speed (D = 6-0.2×(Vgas-0.5)). The independent air supply unit uses air bags to realize partitioned air supply and the wind speed adjustment accuracy reaches ±0.1m / s. The refrigeration fan unit is unevenly distributed to adapt to the partition requirements in the warehouse. In conjunction with the intelligent control module based on the characteristic fusion control of carcass type and volume (species benchmark and dynamic correction of Topt and Hopt), it can simultaneously meet the differentiated environmental requirements of different carcasses such as cattle and sheep in the same acid drainage warehouse, avoid the quality decline of some carcasses (such as over-drying, corruption or incomplete acid drainage) caused by the homogenization of the environment in traditional acid drainage warehouses, and ensure that the quality indicators such as tenderness and pH value of all carcasses after acid drainage are stable and meet the standards.

[0044] Third, the present invention integrates a strain sensor assembly into the movable hanging track, balancing load-bearing and weight monitoring functions. The deployment of environmental control and sensing modules is designed based on practical scenarios such as carcass hanging density and warehouse zoning (for example, the number of image recognition units is calculated as N = ceil(S × ρ / A)), eliminating the need for large-scale modifications to existing acid drainage warehouses. Furthermore, the zoning control of independent air supply units and the distributed design of atomizing sprays reduce overall energy consumption (avoiding energy waste from global environmental regulation), meeting the high-efficiency and energy-saving requirements of industrialized production.
