Description

Technical Field

[0001] This invention relates to the field of feed preparation technology, and in particular to a feed preparation method and system that can improve the intestinal tract of piglets. Background Technology

[0002] Piglets are piglets that grow to a weight of about 30 kilograms from birth. They are also called piglets or seedlings. They have weak thermoregulation and an underdeveloped digestive system. Their stomach weight can increase during the lactation period (by 60 days of age, their stomach weight is several times that at birth, and they grow rapidly). However, they lack immunity and need to obtain antibodies through colostrum. Piglets' respiratory, urinary, and blood systems are similar to those of human newborns, and they are widely used in developmental biology and medical research.

[0003] The core objective of piglet feed preparation is to mimic the high nutritional and digestibility characteristics of breast milk while smoothly transitioning to plant-based feed to support their rapid growth and development and compensate for the weakness of their immature digestive system.

[0004] Existing piglet feed requires post-coating after pelleting. During post-coating, the feed pellets usually contain fine particles and powder, which gradually absorb the coating oil and form oily clumps inside the coating chamber, affecting equipment operation. At the same time, the oily clumps may adhere to the surface of the pellets, causing feed to clump in the subsequent packaging bags, affecting feed quality. Summary of the Invention

[0005] This invention discloses a feed preparation method and system that can improve the intestinal tract of piglets, aiming to solve the technical problem in the background art that feed pellets usually contain fine particles and fine powder, which will form oily powder clumps as the subsequent spraying is carried out, affecting the operation of equipment. At the same time, the oily powder clumps may adhere to the surface of the pellets, causing feed clumping and affecting feed quality.

[0006] This invention proposes a method for preparing feed that can improve the intestinal tract of piglets, comprising the following steps: S1. Raw material selection and pretreatment: High digestibility raw materials such as puffed corn, low-temperature whey powder, steamed fish meal, peeled puffed soybean meal, plasma protein powder, and lactose are selected. Plant-based raw materials such as corn and soybean meal are puffed or cooked to eliminate anti-nutritional factors and improve starch gelatinization. Then all raw materials are crushed. S2. Functional additive premix: Prepare the core premix and add functional ingredients such as probiotics, prebiotics, compound acidifiers, enzyme preparations, zinc sources, taurine and glutamine to the mixture; S3. Mixing process: The pretreated raw materials and premixed materials are put into the mixer to mix them and ensure that all components are evenly distributed; S4. Granulation and Conditioning: Low-temperature granulation process is adopted, and the conditioning temperature is controlled between 60-70℃ to reduce damage to heat-sensitive components and complete the granulation process. S5. Post-coating: After the pellets have cooled, use a pre-coating spraying device to evenly spray oil, heat-sensitive enzyme preparation, probiotics and flavoring agent onto the surface of the pellets to complete feed preparation.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] The present invention discloses a feed preparation method and system that can improve the intestines of piglets. It is mainly applied to scenarios where feed pellets usually contain fine particles and fine powder, and oily powder clumps are formed during the subsequent spraying process, which affects the operation of equipment. At the same time, the oily powder clumps may adhere to the surface of the pellets, causing feed clumping and affecting feed quality.

[0021] Reference Figure 1 A method for preparing feed that can improve the intestinal tract of piglets includes the following steps: S1. Raw material selection and pretreatment: High digestibility raw materials such as puffed corn, low-temperature whey powder, steamed fish meal, peeled puffed soybean meal, plasma protein powder, and lactose are selected.

The conveying hopper 7 is located inside the preparation chamber frame 1. A drive motor 6 is mounted on the conveying bin 7. The output shaft of the drive motor 6 is connected to a spiral conveying roller 8 via a coupling. The spiral conveying roller 8 is located inside the conveying bin 7. Connecting pipe 2 is installed on the preparation chamber frame 1; Spraying separation unit 3 is disposed on the preparation chamber frame 1. Spraying separation unit 3 includes a spraying chamber body 303 and an inner spraying frame 312. The inner spraying frame 312 is disposed on the spraying chamber body 303 and has multiple sieve holes 311. Feed screening module 5 is set on the preparation chamber frame 1. Feed screening module 5 includes screening frame 504 and crushing chamber 502. Multiple screen holes 505 are opened on screening frame 504.

[0023] Reference Figures 2-7 In a preferred embodiment, the spray separation unit 3 further includes: Two electric telescopic rods 301 are provided on the preparation chamber frame 1, and the output ends of the two electric telescopic rods 301 are provided with fixing parts 307. Two tilting motors 302 are respectively mounted on two fixing parts 307. The output shafts of the two tilting motors 302 are connected to the same mounting ring frame 310 through a coupling. The spraying chamber body 303 is mounted on the mounting ring frame 310. Passive gear ring 316 is disposed on the inner spray frame 312 and is located outside the spray chamber body 303.

[0024] In this invention, the spray separation unit 3 further includes: A fixed bracket 306 is mounted on the spray booth body 303. An active motor 315 is mounted on the fixed bracket 306. The output shaft of the active motor 315 is connected to a mounting shaft 327 via a coupling. The driving gear 313 is mounted on the mounting shaft 327 and meshes with the driven gear ring 316. The discharge pipe 304 is installed on the spray booth body 303.

[0025] In this invention, the spray separation unit 3 further includes: A rotating frame 326 is mounted on the inner spraying frame 312, and a linkage wheel 325 is mounted on the rotating frame 326. The drive wheel 314 is mounted on the mounting shaft 327, and the drive wheel 314 and the linkage wheel 325 are provided with the same linkage belt 317. A delivery pump 308 is mounted on a rotating frame 326. A connecting pipe 309 is provided at the input end of the delivery pump 308, and a rear spray agent tank 305 is provided on the connecting pipe 309.

[0026] In this invention, the spray separation unit 3 further includes: Spraying pipe 323 is mounted on delivery pump 308, passes through rotating frame 326, and is located inside inner spraying frame 312; Multiple spray nozzles 322 are provided on the spray pipe 323, and multiple cleaning nozzles 321 are also provided on the spray pipe 323.

[0027] In this invention, the spray separation unit 3 further includes: Two electric push rods 324 are mounted on the rotating frame 326. The output ends of the two electric push rods 324 are provided with the same outer sleeve 319. The inner wall of the outer sleeve 319 is in contact with the outer wall of the spray pipe 323. Multiple spray nozzles 318 are provided on the outer tube 319, and multiple cleaning ports 320 are also provided on the outer tube 319.

[0028] Specifically, during spraying, feed pellets enter the inner spray frame 312. At this time, the rear spray agent tank 305 is connected to the connecting pipe 309. Simultaneously, the delivery pump 308 and the drive motor 315 operate. The drive motor 315 drives the mounting shaft 327 and the drive gear 313 to rotate. Since the drive gear 313 meshes with the passive gear ring 316, the drive motor 315 can drive the inner spray frame 312 to rotate, causing the feed pellets inside to move and be subjected to a certain centrifugal force. At the same time, the delivery pump 308 delivers the spraying additive in the rear spray agent tank 305 to the inside of the spray pipe 323 and sprays it out through the spray nozzle 322. During spraying, the drive wheel 314 can work with the linkage wheel 325 and the linkage belt 317 to drive the rotating frame 326 and the spray pipe 323 to rotate until the spraying operation is completed. At this time, the centrifugal force can throw out the newly generated and entrained fine powder inside the bin in real time. After spraying, the electric telescopic rod 301 operates, which drives the fixed part 307, the tilting motor 302, the mounting ring frame 310 and the spraying chamber body 303 to move, so that one end of the inner spraying frame 312 moves out to connect to the connecting pipe 2. Then, the tilting motor 302 drives the mounting ring frame 310 and the spraying chamber body 303 to tilt and rotate, so that one end of the inner spraying frame 312 faces downward, thereby completing the unloading operation. During spray cleaning, clean water is delivered into the spray pipe 323 through the connecting pipe 309 and the delivery pump 308. At the same time, the electric push rod 324 is operated to push the outer sleeve 319 to move, so that the outer sleeve 319 blocks the spray nozzle 322. Meanwhile, the cleaning port 320 exposes the cleaning nozzle 321, so that the active motor 315 can run again to clean. In specific application scenarios, the spray separation unit 3 is suitable for the spraying stage after piglet feed preparation. That is, the spray separation unit 3 can make feed particles and other materials subject to centrifugal force through the inner spray frame 312 during spraying. As the spraying progresses, the newly generated and entrained fine powder inside the spray chamber body 303 can be thrown out in real time, avoiding the accumulation of fine powder in the chamber and repeated contact with oil. This reduces the chance of fine powder mixing with oil in the spray chamber body 303 to form oily mud, reduces the risk of scaling and clogging, avoids affecting the spraying operation of the spraying equipment, and increases the effectiveness of the device. At the same time, it removes fine powder that would "steal" the spray liquid, improves the proportion and uniformity of functional additives (such as probiotics and enzymes) effectively adhering to the target particles, and improves the quality of feed preparation. It should be noted that the rear spray tank 305 is detachable. When cleaning the equipment, the device can be removed and a cleaning fluid pipeline can be connected to the end of the connecting pipe 309 to assist in cleaning and increase the effectiveness of the device. During cleaning, the device can switch between the cleaning nozzle 321 and the spray nozzle 322 on the spray pipe 323 to ensure the impact force of the cleaning water flow and increase the cleaning effect of the device.

[0029] Reference Figure 2 , Figure 3 , Figure 8 , Figure 9 and Figure 10 In a preferred embodiment, the feed screening module 5 further includes: Mounting bracket 506 is mounted on the preparation chamber frame 1. Mounting bracket 506 is provided with a fixed shaft 507. Fixed shaft 507 is provided with a connecting bracket 515. Servo motor 508 is mounted on mounting bracket 506, and the output shaft of servo motor 508 is connected to one end of fixed shaft 507 via coupling. Mounting frame 511 is mounted on connecting bracket 515. Multiple telescopic springs 509 are mounted on mounting frame 511. One end of each telescopic spring 509 is mounted on the same fixed outer frame 510. Screening frame 504 is mounted on fixed outer frame 510.

[0030] In this invention, the feed screening module 5 further includes: Mounting plate 513 is mounted on mounting frame 511 and a general motor 512 is mounted on mounting plate 513. Cam component 514 is mounted on the output shaft of general-purpose motor 512 via a coupling, and the outer wall of cam component 514 is in contact with the outer wall of fixed outer frame 510.

[0031] In this invention, the feed screening module 5 further includes: Screening guide frame 503 is set on crushing chamber 502, and crushing chamber 502 is set on preparation chamber frame 1; The discharge port 501 is located on the crushing chamber 502.

[0032] Specifically, during screening, feed pellets enter the screening frame 504. At this time, the general-purpose motor 512 drives the cam component 514 to rotate, so that the cam component 514, in conjunction with the telescopic spring 509, drives the fixed outer frame 510 to reciprocate up and down and vibrate, thereby screening the feed pellets. After screening is completed, the servo motor 508 runs, and the servo motor 508 drives the fixed shaft 507 to rotate, and further drives the connecting bracket 515, the mounting frame 511, the fixed outer frame 510 and the screening frame 504 to rotate, so that feed pellets with excessive size inside the screening frame 504 enter the screening guide frame 503 and are further conveyed to the crushing chamber 502 for crushing. After crushing, the feed is discharged through the discharge port 501, completing the feed screening and recycling pretreatment. In specific application scenarios, the feed screening module 5 is suitable for the post-spraying feeding stage of piglet feed. That is, when the feed screening module 5 is in use, it can screen the piglet feed to remove larger particles, thereby ensuring the palatability of the piglet feed and increasing the effectiveness of the device. At the same time, the device can transport the oversized piglet feed after screening to the crushing chamber 502 and crush it, so that the device can effectively recycle this part of the feed (that is, when producing feed, a small amount of this part of the feed can be added to the fresh feed to reduce feed loss), further increasing the effectiveness of the device. It should be noted that during screening, the cooperation of the general-purpose motor 512, the cam component 514 and the telescopic spring 509 can cause the fixed outer frame 510 and the screening frame 504 to vibrate, thus preventing blockage during feeding and screening.

[0033] Working principle: In use, feed pellets are conveyed into the conveying bin 7 through the feed pipe 4 and screened at this time. Then, the drive motor 6 and the screw conveyor roller 8 run to convey the screened feed into the inner spraying frame 312 and perform the post-spraying operation to complete the feed preparation. During screening, feed pellets enter the screening frame 504. At this time, the general motor 512 drives the cam 514 to rotate, which in turn drives the fixed outer frame 510 to reciprocate up and down in conjunction with the telescopic spring 509, thereby screening the feed pellets. After screening, the servo motor 508 runs, which drives the fixed shaft 507 to rotate, and further drives the connecting bracket 515, the mounting frame 511, the fixed outer frame 510 and the screening frame 504 to rotate, so that feed pellets with excessive size inside the screening frame 504 enter the screening guide frame 503 and are further conveyed to the crushing chamber 502 for crushing. After crushing, the feed is discharged through the discharge port 501, completing the feed screening and recycling pretreatment. During spraying, feed pellets enter the inner spray frame 312. At this time, the rear spray agent tank 305 is connected to the connecting pipe 309. Simultaneously, the delivery pump 308 and the drive motor 315 operate. The drive motor 315 drives the mounting shaft 327 and the drive gear 313 to rotate. Since the drive gear 313 meshes with the passive gear ring 316, the drive motor 315 can drive the inner spray frame 312 to rotate, so that the feed pellets inside move and are subjected to a certain centrifugal force. At the same time, the delivery pump 308 delivers the spraying additive in the rear spray agent tank 305 to the inside of the spray pipe 323 and sprays it out through the spray nozzle 322. During spraying, the drive wheel 314 can work with the linkage wheel 325 and the linkage belt 317 to drive the rotating frame 326 and the spray pipe 323 to rotate until the spraying operation is completed. At this time, the centrifugal force can throw out the newly generated and entrained fine powder inside the bin in real time. After spraying, the electric telescopic rod 301 operates, which drives the fixed part 307, the tilting motor 302, the mounting ring frame 310 and the spraying chamber body 303 to move, so that one end of the inner spraying frame 312 moves out to connect to the connecting pipe 2. Then, the tilting motor 302 drives the mounting ring frame 310 and the spraying chamber body 303 to tilt and rotate, so that one end of the inner spraying frame 312 faces downward, thereby completing the unloading operation. During spray cleaning, clean water is delivered into the spray pipe 323 through the connecting pipe 309 and the delivery pump 308. At the same time, the electric push rod 324 operates to push the outer sleeve 319 to move, so that the outer sleeve 319 blocks the spray nozzle 322. Meanwhile, the cleaning port 320 exposes the cleaning nozzle 321, so that the active motor 315 can run again to clean.
