Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of feed feeding, and in particular to a high-efficiency water supply TMR mixing method and system. Background Art
[0002] A total mixed ration (TMR) is a nutritionally balanced diet made by thoroughly mixing and stirring raw materials such as roughage, concentrate, minerals, vitamins, and various additives according to scientific proportions. Its core purpose is to ensure that every bite of feed consumed by livestock contains an even distribution of nutrients, thereby avoiding the picky eating problems common in traditional feeding methods, such as livestock only consuming concentrate and ignoring roughage, resulting in nutritional imbalance. TMR technology breaks down feed stratification through physical mixing, ensuring nutritional comprehensiveness and consistency. The widespread adoption of TMR has become a key support for modern intensive animal husbandry, but its implementation still faces many technical challenges.
[0003] Existing TMR systems typically use a fixed water addition method in the water supply process, and are unable to dynamically adjust according to the real-time initial moisture content of the feed ingredients. This can lead to localized over-wetting or drying of the final mixed ration due to fluctuations in the moisture content of the raw materials, affecting the uniformity and quality of the feed mix. Traditional TMR systems lack dedicated additive addition devices, and the additive delivery process relies on manual operation or simple machinery, resulting in uneven addition and chaotic timing. Additives in different physical forms, such as powder, liquid, or granules, lack isolation measures when added, making them prone to mixing, agglomeration, or cross-contamination in pipelines. For example, powdered additives are prone to dust and adhere to the inner wall of the equipment during the addition process, while liquid additives may penetrate into the untreated material layer, disrupting the uniformity of the formula. This defect increases the risk of feed agglomeration and reduces the uniformity of the distribution of trace components. Existing agitators mostly use a fixed speed mode and cannot be dynamically adjusted according to the form of the additive or the state of the material. A single stirring speed is not effective when processing additives with different physical properties. Low-speed stirring makes it difficult to fully crush granular additives, while high-speed stirring easily causes powdered additives to spread dust, reduce mixing uniformity, and cause excessive crushing or unstretching of feed fibers, affecting the digestion and absorption efficiency of livestock.
[0004] Therefore, it is of great significance to design an efficient water supply TMR mixing method and system to solve the above problems. Summary of the Invention

[0029] Example 1. This example uses the preparation process of a total mixed ration at a goat farm as an example to introduce the specific implementation process of a high-efficiency water supply TMR mixing method of the present invention. The specific formula used in this example includes basic raw materials such as hay and silage corn, as well as three additives: premix, vitamin powder and calcium carbonate particles. When the system is started, the operator enters the formula parameters through the control system 6, including the total weight of the feed. kg, target humidity , target weight of each additive, premix kg, vitamin powder kg, calcium carbonate granules kg. The feeding conveyor 4 first continuously transports the hay and silage corn in proportion to the feed port of the mixer 1. At this time, the control system 6 synchronously starts the water supply device 2. This system uses a submersible pump 22 to inject water at a high flow rate of 30L / min, and uses a weight sensor to monitor the weight change of the water tank 23 in real time: first record the initial weight, and after the submersible pump 22 is started, the control system 6 calculates the cumulative water injection volume every 0.5 seconds. .
[0030] In the formula, the original theoretical water requirement L, control system 6 is based on the total weight of feed design kg and the initial average humidity of the raw materials monitored in real time by the humidity sensor , combined with the preset water-absorbing material compensation coefficient The compensation coefficient is determined by the previous goat feed calibration experiment, or designed based on experience, and the corrected target water volume is calculated. L. When When the feed is heated, the submersible pump 22 is immediately shut down to avoid the moisture content deviation problem caused by the initial humidity fluctuation of the feed raw materials, so that the final mixed humidity error is controlled within ±0.8%.
[0031] During the water injection process, the additive feeding device 3 feeds the materials in batches according to the preset sequence. First, add the powdered premix Type 1: the control system 6 opens the electromagnetic valve corresponding to the storage tank 31, the oscillator 32 vibrates at a frequency of 50Hz to promote the flow of powder, and the weight sensor monitors the weight of the storage tank 31 from the initial value. kg dropped to kg, that is kg, the solenoid valve is closed. The design process takes into account the dust-prone nature of powder and sets a pause time. s, wait for the dust to settle before adding liquid vitamin powder Type 2. When adding liquid additives, the speed of stirrer 1 will automatically increase from the basic 200rpm to rpm, accelerates liquid dispersion; after addition is completed s, finally add granular calcium carbonate Type 3, at this time the stirring speed is further adjusted to rpm to crush particles and delay time s ensures that the particles fully enter the mixing zone. The phased feeding strategy, combined with the physical form differentiation delay, completely eliminates the risk of cross-contamination and agglomeration between different additives. In the above process, the mixing time for the premix is 5 minutes, the mixing time for the vitamin powder is 2 minutes, and the mixing time for the calcium carbonate is 8 minutes.
[0032] Based on the high fiber content of goat feed, the speed is gradually increased to allow the roughage fiber to fully stretch and disperse. After all additives are added, the overall mixing stage begins. The speed of the agitator 1 is linearly increased from 500 rpm to rpm for 8 minutes. When the mixing is finished, the control system 6 opens the discharge door of the stirrer 1 and the finished product is discharged through the discharge conveyor 5.
[0033] It can be seen from Example 1 that the humidity deviation is solved by the coordinated control of the high-speed water supply of the submersible pump 22 and the dynamic water volume correction; a batch strategy of additives based on physical form is designed to eliminate cross contamination; and a staged variable speed stirring mechanism is used to improve mixing uniformity.
[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
