Feed extrusion technology, with its advantages of improving nutrient digestibility, enhancing palatability, and extending shelf life, has become a key technology in feed processing.
[0003] However, traditional poultry and livestock feed extrusion equipment has several problems in use: Due to the wide variety of feed types, different molds are required. In actual production, when changing molds to produce different types of feed, the heavy weight of the molds makes disassembly and assembly inconvenient. Furthermore, ensuring the molds are installed in the optimal position during installation and calibration often requires operators to spend a considerable amount of time. This not only reduces production efficiency and increases labor costs, but also can lead to unstable feed product quality, such as shape deviations and inconsistent extrusion degrees, due to improper mold positioning.

[0023] Combination Figures 1 to 6 As shown, the present invention discloses a poultry and livestock feed processing extrusion device, comprising a base 1, an extrusion box 2, a pre-conditioner 3, and an extrusion die 5.

A drive motor 4 is installed at the rear end of the top of the base 1. A pulley 41 is fixed to the shaft at the front end of the drive motor 4. The pulley 41 is connected to the pulley 43 via a belt. A pulley 42 is fixed to the front end of the pulley 41. The pulley 42 is connected to the pulley 44 via a belt.
[0026] The cutting assembly includes a material cover 6 located at the front end of the extrusion die 5. A servo motor 61 is installed at the front end of the material cover 6. The shaft of the servo motor 61 extends into the interior of the material cover 6 and a cutting wheel 62 is fixed thereon. The cutting wheel 62 is in contact with the front end of the extrusion die 5.
[0027] The replacement component includes an installation groove 73 inside the extrusion die 5, an insert block 7 is installed inside the installation groove 73, an extrusion hole 71 is opened inside the insert block 7, the position of the extrusion hole 71 corresponds to the position of the discharge through hole 51, and a fixing block 72 is fixed on the top of the insert block 7, the fixing block 72 is in contact with the top of the extrusion die 5.
[0028] Fixing holes 721 are provided around the fixing block 72, and fixing screw holes 723 are provided around the top of the mounting groove 73. The fixing screw holes 723 correspond to the fixing holes 721. Fixing bolts 722 are provided inside the fixing holes 721, and the bottom of the fixing bolts 722 extends into the fixing screw holes 723.
[0029] The mounting groove 73 has guide grooves 731 on both sides inside, and guide blocks 732 are fixed on both sides of the embedded block 7. The guide grooves 731 and guide blocks 732 are matched in size, and the guide blocks 732 can slide into the guide grooves 731.
[0030] Specifically, firstly, various feed ingredients, such as grains, beans, and protein ingredients, are mixed according to a certain formula ratio. These ingredients usually need to undergo pretreatment such as crushing and screening to ensure uniform particle size for easy subsequent processing. They are then fed into the preconditioner 3, where steam and an appropriate amount of water are introduced to heat and humidify the ingredients, bringing their moisture content and temperature to a suitable range.
[0031] The pre-conditioned raw material in the pre-conditioner 3 is injected into the extrusion box 2. The drive motor 4 is started to drive pulley 1 41 and pulley 2 42 to rotate. Pulley 1 41 drives pulley 3 43 to rotate through the belt. Pulley 2 42 drives pulley 44 to rotate through the belt. The rotating pulley 3 43 drives the feeding screw 32 in the feeding pipe 31 to rotate, and the pre-conditioned feed raw material in the pre-conditioner 3 is injected into the extrusion box 2 through the feeding hopper 21.
[0032] The rotating pulley 44 drives the extrusion screw 22 to rotate in the puffing chamber of the feed hopper 21. When the feed raw material enters the puffing chamber 2, the rotation of the extrusion screw 22 propels the raw material forward in the puffing chamber. At the same time, due to the gradually decreasing pitch and diameter of the extrusion screw 22, and the resistance of the inner wall of the puffing chamber, the raw material is subjected to strong extrusion, shearing, and friction. During this process, the internal pressure of the raw material rises rapidly, reaching 10-20 MPa, and the temperature also rises to 120℃-180℃. Under the action of high temperature and high pressure, the starch in the raw material is completely gelatinized, the protein is further denatured, and the moisture in the raw material is also in a superheated state. When the raw material is squeezed to the outlet of the puffing chamber, due to the sudden drop in pressure at the outlet, the superheated moisture evaporates instantly, causing the raw material volume to expand rapidly, forming a porous structure, thereby realizing the puffing of the feed.
[0033] The extruded feed passes through the extrusion die 5 installed at the outlet. The extruded feed enters the extrusion hole 71 inside the embedded block 7 through the discharge through-hole 51 at the rear end of the extrusion die 5, and is then extruded through the discharge through-hole 51 at the front end of the extrusion die 5, thus forming the extruded feed into various shapes, such as granules, flakes, and strips. Simultaneously, to control the particle size of the feed, the servo motor 61 is activated to drive the cutting wheel 62 to rotate. The cutting wheel 62 can be of different types of blades. The cutting wheel 62 rotates and cuts at the outlet of the extrusion die 5, cutting the continuously extruded extruded feed into appropriate lengths, thus completing the feed processing and extrusion operation.
[0034] Furthermore, for different types of feed extrusion needs, the insert block 7 with different types of extrusion holes 71 can be directly replaced. The fixing bolt 722 is unscrewed from the fixing screw hole 723 and the fixing hole 721. The fixing block 72 is pulled up to pull the insert block 7 out of the mounting groove 73. Then, the insert block 7 with the required type of extrusion hole 71 is inserted into the mounting groove 73. The guide blocks 732 on both sides of the insert block 7 slide into the guide groove 731 to guide the installation of the insert block 7 and ensure the installation position of the insert block 7.
[0035] When the bottom of the embedded block 7 is in close contact with the inner bottom wall of the mounting groove 73, and the fixing block 72 on the top of the embedded block 7 is in close contact with the top of the extrusion mold 5, the fixing bolt 722 is then inserted through the fixing hole 721 and screwed into the fixing screw hole 723. The fixing bolt 722 is used to fix the fixing block 72 to ensure that the embedded block 7 can be stably installed in the mounting groove 73, thereby completing the change of the mold hole type.
[0036] By replacing the inserts 7 with different types of extrusion holes 71, the extrusion die 5 can be adapted to the puffing requirements of different types of feed. Compared to directly replacing the entire extrusion die 5, the die is designed to be detachable, which not only reduces the overall size of the die, but also avoids the problem of disassembling and reassembling the entire die due to its weight. The smaller die size makes it easier for workers to replace the die, simplifying the operation. More importantly, the installation position of the larger die remains unchanged. Only the small module of the die needs to be disassembled and reassembled, eliminating the need for repositioning and calibration, and placing it in the optimal processing position. This is much more convenient than disassembling the entire die and then reinstalling, adjusting, and calibrating it.
