Description

Technical Field

[0001] This invention relates to the technical field of producing powdered feed for laying hens, and more particularly to a system for producing powdered feed for laying hens. Background Technology

[0002] Laying hens in their mid-to-late stages of growth need to be fed powdered feed. To produce high-quality laying hen powdered feed, multiple process steps are required, mainly including raw material cleaning and screening, raw material crushing, ingredient mixing, addition of additives, and feed maturation and sterilization to reduce bacteria and viruses, promote the gastrointestinal health of laying hens, and increase palatability. Existing feed mill production lines are basically unable to meet all production process requirements at the same time. Manual labor is required to handle the transfer of feed in different production stages. This work is labor-intensive, inefficient, and easily causes feed contamination and grading, thus affecting the safety and uniformity of the finished feed.

[0003] Simply connecting the equipment at each production stage with pipes makes it impossible to adapt the processing to different raw materials and different batches of the same raw material. This results in a lot of unnecessary mechanized repetition in the raw material processing, leading to low work efficiency, poor feed yield, and an inability to meet the current large demand for feed. Furthermore, the high temperature during the cooking and sterilization process of feed can cause vitamins and other trace elements in the additives to lose their activity due to high-temperature conditioning. Therefore, there is an urgent need for an integrated layer hen powder feed production system that can personalize the processing of feed raw materials and ensure the activity of additives. Summary of the Invention

[0008] Furthermore, the first pipeline is connected to a second pipeline via a No. 1 three-way valve, and the other end of the second pipeline is connected to the second scraper conveyor.

[0009] It should be noted in the scheme that the corn impurity removal and screening device includes a double drum screen connected to the corn feeding port, the double drum screen is connected to a TAS combined screen through a sixth pipe, the TAS combined screen is connected to the first pipe, a No. 6 three-way valve is installed on the sixth pipe, the No. 6 three-way valve is connected to the second pipe, and both the double drum screen and the TAS combined screen are connected to impurity bins.

[0010] It is further worth noting that the raw material crushing device group includes a double roller crusher and a hammer crusher connected to the crushing chamber, and both the double roller crusher and the hammer crusher are connected to the batching chamber.

[0011] In a preferred embodiment, a third scraper conveyor is further provided between the first mixer and the powder silo to be heated, and the third scraper conveyor is connected to the batching silo.

[0012] In a preferred embodiment, a fourth scraper machine is further provided between the first mixer and the powder silo to be heated, located below the third scraper machine, and the fourth scraper machine is connected to the third scraper machine.

[0019] Compared with the prior art, the laying hen powder feed production system provided by the present invention includes at least the following:

[0020] Beneficial effects:

[0021] Based on the quality of the purchased corn raw materials, appropriate processing is carried out. Corn of average quality needs to be screened for impurities and then enters the color sorting bin through the first pipe. Then, it enters the corn color sorting device through the third pipe via the first and second scraper conveyors at the bottom of the color sorting bin. The corn color sorting device filters out moldy and defective material, which is then sent to the defective material bin. Good material enters the corn steel silo. Corn of poor quality needs to be screened for impurities and then returned to the corn color sorting device for a second color sorting after screening and color sorting. High-quality corn without mold needs to be screened for impurities and removed by the corn impurity screening device. After removing dust and impurities of all sizes, it can directly enter the corn steel silo through the No. 3 three-way valve of one of the third pipes, bypassing the corn color sorting device. This achieves personalized processing of the main raw materials in the feed. Corresponding cleaning procedures are matched to different cleaning needs of corn, avoiding the mechanical repetition of making all corn undergo the complete cleaning process, and improving the efficiency of cleaning the main raw materials.

[0022] The soybean meal impurity removal device removes impurities from soybean meal, which is used in large quantities in laying hen feed. The removed soybean meal does not need to be crushed and can be directly fed from the soybean meal steel silo into the feed mixing silo through the fifth pipe. Corn raw materials that need to be crushed are fed from the corn steel silo into the crushing silo through the fourth pipe. After being crushed by the raw material crushing device, they are fed into the feed mixing silo. If the purchased soybean meal particles are large, they can also be fed into the crushing silo through the fifth pipe and the No. 5 three-way valve. The above design adapts to the different processing needs of different raw materials and can also be flexibly adjusted for different purchase batches of the same raw material to ensure that the stability of feed quality will not fluctuate greatly due to changes in raw materials.

[0023] By adding additives and mixing them a second time after the feed has been cooked, sterilized, and cooled, the vitamins and other trace elements in the additives can be prevented from losing their activity at the high temperature during the cooking and sterilization process. This not only reduces the bacteria and viruses in the feed during cooking, but also ensures that the additives that can supplement the feed nutrition remain active, thus improving the quality of the produced laying hen feed.

[0031] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] The core of this invention is to provide a layer hen powder feed production system that can personalize and adapt feed ingredients, ensure the activity of additives, and improve feed production rate to flexibly adapt to various production situations.

[0033] Figure 1 This is a schematic diagram of a layer hen powder feed production system provided by the present invention.

Figure 4 This is a schematic diagram of the location of the eighth scraper conveyor provided by the present invention. Figure 5 See the schematic diagram of the position of the ninth scraper conveyor provided by the present invention. Figures 1 to 5 As shown.

[0034] Example 1

[0035] A layer hen meal production system includes a corn impurity removal screening device 1 and a soybean meal impurity removal device 2 for removing impurities from corn and soybean meal. See [link to documentation]. Figure 1The corn impurity removal and screening device 1 is connected to the color sorting bin 4 via the first pipe 3. Before production, the purchased corn undergoes quality inspection by workers, and can be roughly divided into three grades based on impurity content and mold growth: good quality (only some dust and impurities, no mold), average quality (with dust, impurities, and a small amount of mold), and poor quality (with a large amount of dust, impurities, and mold). The average quality corn enters the color sorting bin 4 after being screened by the corn impurity removal and screening device 1 to remove dust and impurities of all sizes, preparing for color sorting. A first scraper conveyor 5 is connected to the bottom of bin 4. The first scraper conveyor 5 is connected to a second scraper conveyor 6. The second scraper conveyor 6 is connected to a corn color sorting device 8 through multiple third pipes 7. After impurities are removed in the color sorting bin 4, the corn is simultaneously fed into the corn color sorting device 8 through the first scraper conveyor 5 and the second scraper conveyor 6 via the multiple third pipes 7 for color sorting. The bottom of the corn color sorting device 8 is connected to a corn steel silo 10. The corn that has been color sorted is stored in the corn steel silo 10. The moldy and spoiled material that has been screened out is sent to the spoilage bin 1 at the bottom of the corn color sorting device 8. 1. At this point, corn of average quality undergoes two processes—corn impurity removal and screening device 1 and corn color sorting device 8—to remove dust, impurities of different sizes, and moldy corn, meeting the raw material cleaning quality requirements. A third pipe 7 is connected to a corn steel silo 10 via a three-way valve 9. Corn of good quality, after manual inspection, flows into the color sorting silo 4 after impurity removal and into the third pipe 7 equipped with the three-way valve 9, directly entering the corn steel silo 10 for storage, bypassing the color sorting process. The top and bottom of the corn color sorting device 8 are connected. Corn of poor quality, after manual inspection, returns from the bottom of the corn color sorting device 8 to its top for secondary color sorting before entering the corn steel silo 10. This ensures that this batch of lower-quality corn meets the raw material quality requirements. This design allows for matching appropriate cleaning processes to different cleaning needs for corn of varying quality, avoiding the need for uniform, mechanized cleaning and screening of all corn raw materials. This eliminates unnecessary mechanization and improves the cleaning efficiency of corn, the main raw material in laying hen feed.

[0036] Soybean meal, after impurities are removed by the soybean meal impurity removal device 2, enters the soybean meal steel silo 12 connected to the device. Generally, soybean meal particles are small and do not require further crushing; therefore, they can directly enter the batching silo 14 from the soybean meal steel silo 12 through the fifth pipe 13. Corn, however, has larger particles and requires crushing. Therefore, the corn in the corn steel silo 10 enters the crushing chamber 16 through the fourth pipe 15. The crushing chamber 16 is connected to a raw material crushing device group 17, which is connected to the batching silo 14. The crushed corn is then fed into the batching silo 14. This process is suitable for both corn and soybean meal. The system can be adapted to different processing needs, enabling personalized processing of the main raw materials in laying hen feed formulations. While cleaning and improving the quality of raw materials, it also ensures processing efficiency. Since there are times when soybean meal particles are purchased in large quantities, in order to avoid fluctuations in feed quality due to the situation of the purchased raw materials, which would affect the uniformity of the finished powder, the fifth pipe 13 is connected to the grinding chamber 16 through the No. 5 three-way valve 18. Larger batches of soybean meal can also enter the grinding chamber 16 through the No. 5 three-way valve 18 to participate in the raw material grinding process, making the processing of the same raw materials with different purchase batches and different quality conditions more flexible and reliable.

[0037] The feed mixing hopper 14 is connected to a weighing hopper 19, which stores various raw materials for preparing laying hen feed. The weighing hopper 19 is connected to a first mixer 20. Specified amounts of each raw material are weighed out by the weighing hopper 19 and fed into the first mixer 20. The first mixer 20 is connected to a preheating powder hopper 21, where the evenly mixed feed is stored for maturation. A preheating powder maturation device 22 is connected to the bottom of the preheating powder hopper 21. This device performs high-temperature steaming and sterilization on the mixed powder, removing a large amount of mycotoxins and bacteria from the raw feed to improve the digestibility, palatability, and particle size uniformity of the laying hen feed. The preheating powder maturation device 22 is connected to a semi-finished product hopper 23, where the cooked feed, after maturation and sterilization and cooling to room temperature, enters. The semi-finished product hopper 23 is connected to the weighing hopper 19. The top of the weighing hopper 19 is connected to a premixed additive bin 24. The weighing hopper 19 weighs a specified proportion of the cooked semi-finished product and the premixed additives, which are then fed into a second mixer 25 connected to the weighing hopper 19 for secondary mixing. The second mixer 25 is connected to a finished product bin 26. The finished feed, after being evenly mixed with the cooked semi-finished product and the premixed additives, is stored in the finished product bin 26 for shipment. By first mixing all raw materials except for additives, which may be deactivated by high temperatures, cooking and sterilizing them, and then cooling them, the additives are added for secondary mixing. This avoids the loss of activity of trace elements such as vitamins in the additives due to high-temperature conditioning during the cooking and sterilization process, thus ensuring the biological activity of the laying hen feed. Furthermore, the secondary mixing can prevent the separation of feed caused by hot powder conditioning, ensuring that the finished laying hen feed achieves optimal uniformity.

[0038] See Figure 2 To further improve the efficiency of raw material cleaning, the first pipeline 3 is connected to the second pipeline 28 via the first three-way valve 27. The other end of the second pipeline 28 is connected to the second scraper conveyor 6. Corn with good quality that does not need to be color sorted can flow directly through the second pipeline 28 and the second scraper conveyor 6 into the third pipeline 7 equipped with the third three-way valve 9, and then directly into the corn steel silo 10 through the third three-way valve 9, passing over the waiting color sorting silo 4 and the corn color sorting device 8. In actual production, if the waiting color sorting silo 4 or the corn steel silo 10 malfunctions, both can serve as emergency reserve silos for each other.

[0039] In one feasible implementation, the corn impurity removal and screening device 1 includes a double-drum screen 110 connected to the corn feed inlet 100. The double-drum screen 110 is connected to a TAS combined screen 130 via a sixth pipe 120. The TAS combined screen 130 is connected to a first pipe 3. Corn of average and poor quality enters the double-drum screen 110 from the corn feed inlet 100 for primary screening, and then enters the TAS combined screen 130 for secondary screening. A No. 6 three-way valve 140 is installed on the sixth pipe 120, and the No. 6 three-way valve 140 is connected to the second pipe 3. Pipeline 28 connects the corn, which, after passing through the double drum screen 110 for one screening, can enter the second pipeline 28 through the No. 6 three-way valve 140, bypassing the color sorting bin 4 and the corn color sorting device 8, and directly enter the corn steel silo 10. Impurities of different sizes screened out by the double drum screen 110 and the TAS combined screen 130 enter the impurity bin 150 connected to the two. By flexibly applying the two-stage screening, more refined processing can be carried out according to the quality of the corn raw materials, ensuring the corn cleaning effect while improving the cleaning efficiency.

[0040] In one feasible implementation, the raw material crushing device group 17 includes a roller crusher 170 and a hammer crusher 171 connected to the crushing chamber 16. Both the roller crusher 170 and the hammer crusher 171 are connected to the feeding chamber 14. The roller crusher 170 and the hammer crusher 171 can crush corn raw materials into two different particle sizes of corn powder. When preparing laying hen feed, mixing corn of two different particle sizes can improve the nutritional value of the laying hen feed and promote the intestinal absorption and health of the laying hens.

[0041] Example 2

[0042] Based on Example 1, see [link / reference] Figure 2To improve the stability of the entire production system, an emergency contingency plan is designed to address potential production errors or interruptions caused by unforeseen circumstances that could paralyze feed production. This plan aims to respond appropriately to emergencies, promptly restore or correct production errors, and avoid irreparable economic losses. A third scraper conveyor 29 is also installed between the first mixer 20 and the waiting powder silo 21. The third scraper conveyor 29 is connected to the batching silo 14. In the event of a sudden power outage, the powder that has not been fully mixed in the first mixer 20 can be returned to the batching silo 14 via the third scraper conveyor 29, and then re-enter the first mixer 20 through the batching hopper 19 for further mixing. This ensures that the powder that was not fully mixed before the power outage is mixed evenly before entering the subsequent maturation process.

[0043] Furthermore, when the hot powder curing device 22 is damaged, a fourth scraper 30 is installed between the first mixer 20 and the powder waiting to be heated silo 21, located below the third scraper 29. The fourth scraper 30 is connected to the third scraper 29. A fifth scraper 31 is installed between the second mixer 25 and the finished product silo 26, connected to the fourth scraper 30. The raw material on the fourth scraper 30 that has not yet entered the powder waiting to be heated silo 21 can pass over the damaged hot powder curing device 22 and directly enter the finished product silo 26 through the fifth scraper 31, so as to avoid interruption of feed supply to the farm, causing the laying hens to run out of feed and thus damaging the growth and development of the laying hens, resulting in irreparable economic losses. In this case, direct delivery of raw material can be used as an emergency alternative.

[0044] See Figure 3 Preferably, essential fatty acids can maintain the stability of cells in laying hens and ensure their growth and development. Oil is the main source of essential fatty acids. Therefore, the first mixer 20 is also connected to an oil adding device 32. Oil can be added to the raw materials in the first mixer 20 through the oil adding device 32. After the raw materials and oil are evenly mixed in the first mixer 20, they are sent to the hot powder cooking device 22. The high-temperature cooking process of the hot powder cooking device 22 can make the powder and oil mix more thoroughly.

[0045] Preferably, the powder after maturation exhibits a certain degree of clumping. By setting a safety screen 33 between the hot powder maturation device 22 and the semi-finished product silo 23 to screen out large pieces of material in the maturation, the uniformity of the subsequent finished powder can be avoided.

[0046] When the corn steel silo 10 malfunctions, to ensure the safety of stored quality, a sixth scraper 34 is installed between the corn color sorting device 8 and the corn steel silo 10. A seventh scraper 35 connected to the fourth pipe 15 is also installed at the bottom of the corn steel silo 10. The sixth scraper 34 and the seventh scraper 35 are connected. The color-sorted corn can be directly transported from the fourth pipe 15 through the sixth scraper 34 and the seventh scraper 35 to the crushing bin 16, ensuring that the production system can continue to operate after the corn steel silo 10 is damaged. When the demand for laying hen feed is high, and the total amount of cleaned corn is basically balanced with the demand for preparing laying hen feed, the corn no longer passes through the corn steel silo 10, but is directly transported to the next crushing process, which can further improve the production rate of laying hen feed.

[0047] See Figure 4 and Figure 5 Preferably, during storage, the corn and soybean meal in the corn silo 10 and soybean meal silo 12 continuously release heat due to seed respiration, causing the corn and soybean meal to heat up. Therefore, an eighth scraper 36 is also installed between the seventh scraper 35 and the fourth pipe 15, located below the seventh scraper 35. The eighth scraper 36 is connected to the top of the corn silo 10. The corn in the corn silo 10 can flow out of the corn silo 10 and then return to the corn silo 10 via the eighth scraper 36, so as to realize the dynamic circulation of corn from one corn silo 10 to another corn silo 10 or using the same corn silo 10, so that the corn... The corn inside the steel silo 10 is cooled during this transfer process. A ninth scraper conveyor 37 is also installed between the soybean meal steel silo 12 and the fifth pipe 13. The ninth scraper conveyor 37 is connected to the top of the soybean meal steel silo 12. The ninth scraper conveyor 37 can be used to transfer the soybean meal inside the soybean meal steel silo 12 to reduce the temperature of the soybean meal. The eighth scraper conveyor 36 and the ninth scraper conveyor 37 can solve the problem of heat generated by the respiration of corn and soybean meal, improve storage safety and the flow and ventilation of corn and soybean meal, ensure the quality of raw material storage, and prevent corn and soybean meal from becoming moldy due to heat and insufficient ventilation during storage in the corn steel silo 10 and soybean meal steel silo 12.

[0048] This invention personalizes the processing of key feed ingredients, matching corresponding cleaning processes to different cleaning needs of the same ingredient. High-quality corn only requires impurity removal and screening, while average-quality corn requires both impurity removal and color sorting. Low-quality corn is returned to the corn color sorting device 8 for secondary color sorting. This avoids unnecessary mechanical repetition of different quality ingredients undergoing the same cleaning process. Furthermore, it adapts the processing to the different needs of corn and soybean meal. Corn requiring crushing enters the crushing bin 16, while soybean meal that does not require crushing goes directly to the mixing bin 14. If the purchased soybean meal particles are large, they can also be processed through five... The three-way valve 18 leads into the grinding chamber 16, which avoids the impact of raw materials on feed quality and improves raw material cleaning efficiency. The secondary mixing additive can prevent the vitamins and other trace elements in the additive from losing their activity at high temperatures during the cooking and sterilization process. To improve the stability of the entire production system, emergency backup measures are designed for sudden power outages, damage to the hot powder cooking device 22, and the storage quality and safety of the corn steel silo 10 and soybean meal steel silo 12. This enables the production system to respond properly to emergencies, restore or correct production errors in a timely manner, and avoid irreparable economic losses caused by the paralysis of laying hen powder production due to emergencies.
