Abstract
Description
Technical Field
[0001] This application relates to the technical field of feed processing, and in particular to a processing equipment and process for soft pellet feed for large yellow croaker. Background Technology
[0002] In the process of processing soft pellet feed for large yellow croaker, the raw materials are first processed into soft pellet structure through low-temperature extrusion, and then the feed pellets are sprayed with oil through an oil spraying device.
[0003] The most common oil spraying equipment is an oil spraying mixing drum. The expanded feed pellets are put into the mixing drum, and then the mixing drum is started to stir the feed pellets. At the same time, the nozzles on the mixing drum spray oil, so that the feed pellets are coated with oil.
[0004] However, the feed pellets after low-temperature puffing have a soft pellet structure. When collecting the feed sprayed from the puffing machine, the feed pellets are squeezed together and tend to stick together. During the oil spraying process, some feed pellets may be stuck together, resulting in some feed pellets not being in contact with the oil, which leads to uneven oil distribution. Summary of the Invention
[0005] In order to improve the uniformity of oil distribution in feed pellets, this application provides a processing equipment and process for soft pellet feed for large yellow croaker.
[0006] In the first aspect, this application provides a processing equipment for soft pellet feed of large yellow croaker, which adopts the following technical solution:
[0007] A processing equipment for soft pellet feed of large yellow croaker, including
[0008] The fuel injection tank has a fuel injection groove.
[0009] A feed box is located on top of the fuel injection tank, and the feed box is equipped with a feed valve;
[0010] A discharge box is located at the bottom of the oil spray box and away from the feed box, and the discharge box is equipped with a discharge valve.
[0011] A vacuum device is installed on the outer wall of the fuel injection tank, and the vacuum device is connected to the fuel injection slot.
[0012] The conveyor rollers are arranged in multiple sets, spaced vertically in a stepped manner, and the feed box conveys feed pellets to each set of conveyor rollers.
[0013] Each group of conveyor rollers has multiple rollers, which are evenly spaced along the horizontal direction toward the discharge box.
[0014] The drive unit, located in the oil injection box, drives the conveyor roller to convey feed pellets toward the discharge box.
[0015] The oil injection tank is equipped with a support plate, which is located between adjacent conveyor rollers in the same group, and the support plate restricts feed particles from falling between adjacent conveyor rollers in the same group;
[0016] The oil injection box is equipped with an oil supply pipe, which corresponds one-to-one with each group of the transmission rollers. The oil supply pipe is located above each group of the transmission rollers and away from the feed box.
[0017] Atomizing nozzles are disposed on and connected to the oil supply pipe, and there are multiple atomizing nozzles that are spaced apart along the extension direction of the oil supply pipe;
[0018] A fuel supply tank is located on the outer wall of the fuel injection tank, and a fuel supply pump is installed inside the fuel supply tank to supply fuel to the fuel supply pipe.
[0019] By adopting the above technical solution, during production, feed particles enter the oil spraying tank and then fall relatively evenly onto the conveyor roller. The feed particles are conveyed towards the discharge box under vacuum, and the volume of the feed particles gradually increases during the conveying process. At the same time, when the feed particles that are stuck together move to the center axis of the conveyor roller, the feed particles separate from each other under the action of gravity, so that the feed particles are dispersed. Finally, the oil is sprayed out through the atomizing nozzle, so that the outer periphery of the feed particles can be relatively evenly coated with oil, improving the uniformity of oil distribution in the feed particles.
[0020] Optionally, the outer periphery of the transmission roller is formed with multiple sets of actuating grooves along the circumferential direction, and each set of actuating grooves has multiple grooves and is evenly spaced along the axial direction of the transmission roller.
[0021] By adopting the above technical solution, the effect of the conveyor roller in rotating the feed pellets is improved.
[0022] Optionally, the transmission roller is provided with a toggle block that slides circumferentially in the toggle groove, and the transmission roller is provided with a drive assembly;
[0023] When the transmission roller rotates to a position where the actuating block is above and adjacent to the support plate, the drive assembly drives the actuating block to slide along the axial direction of the transmission roller.
[0024] By adopting the above technical solution, the driving actuating block is slidable, thereby improving the oil spraying effect of the feed pellets.
[0025] Optionally, the drive assembly includes a drive column, a drive spring, and a push block;
[0026] The drive column slides axially on the transmission roller. There are multiple drive columns and they correspond to each group of actuating blocks. The actuating blocks in the same group are respectively arranged on the same drive column.
[0027] The drive spring is disposed inside the transmission roller, and the drive spring drives the end of the drive column to protrude outside the transmission roller, and the end of the drive column slides on the wall of the oil injection groove;
[0028] The push block is symmetrically arranged on the wall of the oil injection groove. The push block is located adjacent to the support plate. The push block forms a push surface for the drive column to slide. When the drive column slides on the push surface, the drive column slides into the transfer roller.
[0029] By adopting the above technical solution, the push block and the drive spring cooperate with each other to push the drive column to slide, so that the agitator block slides in the agitator groove, thereby realizing the agitation of feed pellets.
[0030] Optionally, the peripheral corners of the actuating block are each formed with an arc surface structure.
[0031] By adopting the above technical solution, the possibility of feed pellets being scraped and falling off when the agitator moves the feed pellets is reduced.
[0032] Optionally, multiple oil leakage holes are formed on the support plate.
[0033] By adopting the above technical solution, the oil can drip downwards, making it easy to recycle; and during the dripping process, it can come into contact with the feed pellets below, further improving the oil spraying effect of the feed pellets.
[0034] Optionally, the fuel injection tank is equipped with a fuel pump located at the bottom of the fuel injection slot, and the fuel pump is equipped with a fuel delivery pipe connected to the fuel supply tank.
[0035] By adopting the above technical solution, the oil pump extracts the collected grease, making it convenient to recycle and reuse the grease.
[0036] Secondly, this application provides a processing technology for soft pellet feed for large yellow croaker, employing the following technical solution:
[0037] A processing method for soft pellet feed for large yellow croaker includes the following steps:
[0038] S1: Raw material mixing;
[0039] S2: The mixed raw materials are ultra-finely pulverized and sieved before being steam-conditioned;
[0040] S3: Low-temperature extrusion of conditioned feed;
[0041] S4: The low-temperature puffed feed pellets are placed into the feed box, oil is sprayed onto the feed pellets through the oil spray box, and then the oiled feed pellets are output from the discharge box.
[0042] By adopting the above technical solution, oil is sprayed through an oil spraying box during the feed pellet production process, which separates the sticky feed pellets and improves the uniformity of the oil after the feed pellets are sprayed.
[0043] In summary, this application includes at least one of the following beneficial effects:
[0044] 1. The feed pellets gradually increase in volume under vacuum. During the transmission process, when the feed pellets are stuck together and move to the center of the transmission roller, they separate from each other under the action of gravity, which helps to improve the uniformity of oil distribution in the feed pellets after oil spraying.
[0045] 2. By moving the feed pellets with the agitator, the uniformity of contact between the feed pellets and the oil is improved. Attached Figure Description

[0054] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.
[0055] This application discloses a processing equipment for soft pellet feed of large yellow croaker. See also: Figure 1 and Figure 2 The processing equipment includes an oil spray box 1, a feed box 2, and a discharge box 3. The oil spray box 1 is placed on the ground via its own support. The oil spray box 1 has a cuboid structure with its length parallel to the ground, and an oil spray groove 11 extending along its length is formed inside. The feed box 2 is fixedly located at the top of the oil spray box 1, near its width. The feed box 2 is connected to a feed pipe, through which the low-temperature puffed feed pellets are fed into the feed box 2. The feed box 2 is connected to the oil spray groove 11 and is equipped with a feed valve 21. During production, the feed valve 21 controls the speed and quantity of feed delivered from the feed box 2 into the oil spray groove 11. The discharge box 3 is fixed at the bottom of the oil spray box 1, near its other width, and is located away from the feed box 2. The discharge box 3 is connected to the oil spraying tank 11 and the discharge pipe is connected to the discharge box 3. The discharge box 3 is equipped with a discharge valve 31. The oil-sprayed feed particles are collected in the discharge box 3, and the discharge valve 31 controls the discharge box 3 to output the oil-sprayed feed particles into the discharge pipe.
[0056] The processing equipment also includes a vacuum device 12, which mainly consists of a vacuum pump and an air extraction pipe. The air extraction pipe is fixed to and connected to the vacuum pump. The vacuum device 12 is fixed to the outer wall of the oil spray tank 1. When the vacuum device 12 is activated, it extracts the air from the oil spray tank 11 through the air extraction pipe, creating a vacuum environment in the oil spray tank 11. At this time, the feed pipe and the discharge pipe are closed. When the oil spray tank 11 is in a vacuum environment, feed particles enter the oil spray tank 11, and as time goes by, the volume of the feed particles gradually expands and grows.
[0057] The processing equipment also includes transfer rollers 13 and a drive unit. The transfer rollers 13 are rotatably connected to the oil injection box 1 and located within the oil injection groove 11. The length direction of the transfer rollers 13 is perpendicular to the length direction of the oil injection box 1. There are multiple sets of transfer rollers 13, arranged in a stepped structure with vertical spacing. The distance between the lowermost set of transfer rollers 13 and the side wall of the oil injection box 1 adjacent to the feed box 2 in the width direction is the smallest, while the distance between the uppermost set of transfer rollers 13 and the side wall of the oil injection box 1 adjacent to the feed box 2 in the width direction is the largest. When feed pellets are fed into the feed box 2, the feed pellets can fall onto each set of transfer rollers 13. There are multiple sets of transfer rollers 13, which are evenly spaced along the length direction of the oil injection box 1 on the horizontal plane. The drive unit is located in the oil injection box 1 and is used to drive the transfer rollers 13 to rotate synchronously, so that the transfer rollers 13 transport the feed pellets from the feed box 2 side to the discharge box 3 side. At the same time, when the feed pellets are separated from each set of conveyor rollers 13, the feed pellets fall downwards under the action of gravity until they fall into the discharge box 3, thus achieving the effect of collecting the feed pellets after oil spraying.
[0058] The fuel injection tank 1 is equipped with multiple support plates 14, which are respectively positioned between two adjacent conveyor rollers 13 in the same group. The support plates 14 are located near the bottom of the conveyor rollers 13 and are used to support the feed pellets. When feed pellets fall from the feed box 2 onto the conveyor rollers 13, the feed pellets are small in size and some of them stick together. At this time, as the conveyor rollers 13 transport the feed pellets from the feed box 2 side to the discharge box 3 side, the support plates 14 support the feed pellets, reducing the possibility of feed pellets falling between two adjacent conveyor rollers 13. During the transport process, the feed pellets gradually expand and grow. At the same time, when the sticky pellets pass through the conveyor rollers 13 one after another, when the sticky feed pellets move to the top of the conveyor rollers 13, the feed pellets separate away from the sticky position under the action of gravity, which helps the feed pellets gradually disperse into individual pellet structures during the transport process.
[0059] See Figure 2 and Figure 3 The drive unit includes a drive motor 4, a drive gear 41, a connecting gear 42, a connecting chain 43, and a drive chain 44. The same end of each transmission roller 13 extends outward from the fuel injection tank 1, and the end of the transmission roller 13 protruding from the fuel injection tank 1 is connected to the fuel injection tank 1 via a rotary seal. The drive gear 41 corresponds one-to-one with the transmission roller 13 and is fixed to the end of the transmission roller 13, and the drive gear 41 is located outside the fuel injection tank 1.
[0060] There are multiple drive chains 44, each corresponding to a group of transmission rollers 13. Each drive chain 44 is connected end-to-end and sleeved on the outer periphery of the drive gear 41 of the same group of transmission rollers 13. In use, the drive chains 44 drive the same group of transmission rollers 13 to rotate synchronously. There are multiple connecting gears 42, each corresponding to a group of transmission rollers 13. The connecting gears 42 are fixed on the outer periphery of the end of the transmission rollers 13 and located outside the fuel injection tank 1. Connecting chains 43 are connected end-to-end and sleeved on the outer periphery of the connecting gears 42. In use, the connecting chains 43 realize the synchronization of each group of transmission rollers 13.
[0061] The drive motor 4 is fixed to the outer periphery of the fuel injection tank 1 by its own bracket, and the output shaft of the drive motor 4 is fixedly connected to one of the uppermost conveyor rollers 13. When the drive motor 4 starts, it drives the conveyor roller 13 to rotate. Then, the adjacent conveyor rollers 13 are linked by the drive chain 44, and the upper and lower adjacent conveyor rollers 13 are linked by the connecting chain 43. When the conveyor rollers 13 rotate synchronously, the feed pellets are conveyed from the feed box 2 to the discharge box 3.
[0062] See Figure 2 and Figure 4 The oil injection box 1 is equipped with oil supply pipes 15. There are multiple sets of oil supply pipes 15, and each set of oil supply pipes 15 corresponds to a set of transmission rollers 13. At the same time, each set of oil supply pipes 15 is located directly above the corresponding transmission roller 13 and away from the feed box 2. There are multiple sets of oil supply pipes 15, which are evenly spaced along the length of the oil injection box 1, and each set of oil supply pipes 15 is interconnected.
[0063] The processing equipment also includes an atomizing nozzle 16 and an oil supply tank 17 (the oil supply tank 17 is located in...). Figure 1 (Selected from the bid) There are multiple atomizing nozzles 16, which are evenly spaced along the length of the oil supply pipe 15. The atomizing nozzles 16 are located at the bottom of the oil supply pipe 15 and are connected to each other.
[0064] See Figure 1 and Figure 2 The fuel supply tank 17 is fixed to the outer wall of the fuel injection tank 1. A fuel supply pump 171 is fixedly connected inside the fuel supply tank 17 and is connected to the fuel supply pipe 15. A suction pump 18 is fixedly connected to the fuel injection tank 1. The suction pump 18 is located on the bottom wall of the fuel injection slot 11 and is fixedly connected to a delivery pipe 181, which is connected to the fuel supply tank 17. During use, the suction pump 18 draws the grease collected at the bottom of the fuel injection slot 11 and then transfers it to the fuel supply tank 17 through the delivery pipe 181, which facilitates the recycling of the grease.
[0065] See Figure 4 During oil injection, the grease is stored in the oil supply tank 17 (oil supply tank 17 is in Figure 1Within the feed pellets (as indicated by the bid), the oil pump 171 draws the grease stored in the oil supply tank 17 and first transmits it through the oil supply pipe 15. Then, the atomizing nozzle 16 atomizes the grease in the oil supply pipe 15 and sprays it downwards, allowing the passing feed pellets to come into contact with the grease. Because the outer periphery of the dispersed feed pellets has an arc-shaped structure, the conveying roller 13 can drive the feed pellets to rotate during the conveying process, increasing the contact area with the atomized grease and improving the uniformity of grease distribution within the feed pellets.
[0066] Meanwhile, oil leakage holes 141 are evenly spaced on the support plate 14. The grease that falls on the support plate 14 drips down through the oil leakage holes 141. On the one hand, the grease can come into contact with the grease being transported during the dripping process, and on the other hand, the grease can flow down continuously until it collects at the bottom of the oil spray groove 11.
[0067] See Figure 5 In other embodiments, to further improve the conveying effect of the conveyor roller 13 and its ability to rotate feed pellets during conveying, actuation grooves 131 are formed on the outer periphery of the conveyor roller 13. Multiple sets of actuation grooves 131 are spaced circumferentially, with each set containing multiple grooves evenly spaced along the axial direction of the conveyor roller 13. Each actuation groove 131 extends along the length of the conveyor roller 13. During the conveying of feed pellets by the conveyor roller 13, some feed pellets become lodged in the actuation grooves 131, thus improving the actuation effect of the conveyor roller 13.
[0068] The transmission roller 13 is provided with actuating blocks 5, which correspond one-to-one with actuating grooves 131, and the actuating blocks 5 slide along the axial direction of the transmission roller 13 within the actuating grooves 131. The shape of the actuating blocks 5 is adapted to the actuating grooves 131, and the side of the actuating blocks 5 away from the central axis of the transmission roller 13 has an arc surface structure, which is the same as the extension trajectory of the outer periphery of the transmission roller 13.
[0069] The transmission roller 13 is equipped with a drive assembly, which includes a drive column 6, a drive spring 61, and a push block 62. There are multiple drive columns 6, each corresponding to a set of actuating blocks 5. The transmission roller 13 has an axially extending drive groove 132, with one side of the drive groove 132 extending beyond the transmission roller 13. The drive column 6 slides in the drive groove 132, with its central axis parallel to the central axis of the transmission roller 13. The actuating block 5 is fixed to the outer periphery of the drive column 6 near the central axis of the transmission roller 13. The drive spring 61 corresponds to each drive column 6 and is installed within the drive groove 132. One end of the drive spring 61 abuts against the drive column 6, and the other end abuts against the groove wall of the drive groove 132 away from the groove opening. When the drive spring 61 is released elastically, it pushes the drive column 6 to protrude beyond the drive groove 132, at which point the actuating block 5 abuts against one side of the groove wall of the actuating groove 131.
[0070] See Figure 6 and Figure 7Multiple push blocks 62 are fixed on the side wall of the fuel injection slot 11 facing the opening of the drive slot 132. The push blocks 62 are located on the support plate 14 (the support plate 14 is in Figure 4 The position is located above and near the support plate 14 (marked in the middle). The push block 62 is inclined to form a push surface 621, and the end of the drive column 6 has an arc surface structure.
[0071] See Figure 5 and Figure 7 During the rotation of the transmission roller 13, the end of the drive column 6 slides on the pushing surface 621. At this time, the pushing block 62 pushes the drive column 6 into the drive groove 132, and the drive column 6 drives the agitator block 5 to slide in the agitator groove 131. When the drive column 6 moves away from the pushing block 62, the drive spring 61 is released elastically, pushing the drive column 6 to slide out of the drive groove 132. At this time, the drive column 6 drives the agitator block 5 to slide in the same direction. When the feed pellets are conveyed by the transmission roller 13 through the support plate 14, the agitator block 5 slides back and forth. At this time, the agitator block 5 agitates the feed pellets circumferentially along the transmission roller 13, so that the area of the feed pellets that can contact the oil is increased. In addition, the corners of the agitator block 5 are formed with arc surface structures, reducing the possibility of scraping off some feed pellets during the contact between the agitator block 5 and the feed pellets.
[0072] The implementation principle of the large yellow croaker soft pellet feed processing equipment in this application embodiment is as follows:
[0073] Low-temperature expanded feed pellets in feed box 2 enter oil spray tank 11, and then fall onto conveyor roller 13, being conveyed towards discharge box 3. During the conveying process, the sticky feed pellets gradually disperse, and a vacuum is drawn in oil spray tank 11, causing the feed pellets to gradually expand and grow. Then, during the conveying process, they come into contact with atomized oil, achieving oil spraying treatment of the feed pellets.
[0074] On the other hand, this application discloses a processing technology for soft pellet feed for large yellow croaker, including the following steps:
[0075] Step 1: Mix the proportioned feed ingredients;
[0076] Step 2: The mixed raw materials are pulverized using an ultra-fine pulverizer and then sieved through an 80-mesh sieve before being steam-conditioned.
[0077] Step 3: Perform low-temperature puffing on the conditioned feed;
[0078] Step 4: Place the low-temperature puffed feed pellets into the feed box 2, spray oil onto the feed pellets through the oil spray box 1, and then output the oiled feed pellets from the discharge box 3.
[0079] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
