[0043] Specifically, the extrusion barrel 100, the bottom side of the extrusion barrel 100 is provided with an extrusion assembly 101, the extrusion assembly 101 includes a first hollow shaft 101a rotatably connected to the inner wall of the extrusion barrel 100 and spike rods 101c evenly spaced along the circumferential direction of the first hollow shaft 101a, one end of the first hollow shaft 101a passes through the bearing on the inner wall of the extrusion barrel 100 and is transmission-connected to the first driving device 101b, one end of the extrusion barrel 100 is provided with a granulating mechanism 102, and the top side of the extrusion barrel 100 is connected to the first driving device 101b through a pipeline. It is connected to a mixing barrel 103; a water adding component 200, including a water tank 201 placed below the extrusion barrel 100 and a water outlet pipe 201a arranged at the bottom of the outer wall of one side of the water tank 201, and the other end of the water outlet pipe 201a is connected to the water pump 202 through a pipe joint; and an adjustment component 300, including a connecting frame 301 arranged on the outside of one end of the extrusion barrel 100 and a first motor 306 installed inside the connecting frame 301, and the front and rear ends of the connecting frame 301 are respectively fixedly connected with a first sealing block 302 and a second sealing block 303.

[0044] For details, please refer to Figure 8 , Fig.10 and Fig.11 The water outlet of the water pump 202 is connected to the first connecting pipe 202a through a pipe joint, and the other end of the first connecting pipe 202a is connected to the water inlet pipe 203 through a pipe joint, and the other end of the water inlet pipe 203 is rotatably connected to the inner outer end of the first hollow shaft 101a; the pipes on one side end faces of the first sealing block 302 and the second sealing block 303 are connected to the external steam pipe 304 through a pipe joint, and the top and bottom of the first sealing block 302 and the second sealing block 303 are both provided with internal steam pipes 305, and a driving chain is installed on the output shaft of the first motor 306. The outer wall of the driving sprocket 306a is connected to the outer wall of the driven sprockets 307b on both sides through a chain, and a first rotating shaft 307a is installed at the center of one end surface of the driven sprocket 307b. The other end of the first rotating shaft 307a passes through the adjacent first sealing block 302 and the bearing on the end surface of one side of the first sealing block 302 and is connected to one side wall of the four-way sealing column 307; wherein the internal steam pipe 305 is embedded in the inner wall of the extrusion barrel 100, and the four-way sealing column 307 is rotatably installed inside the first sealing block 302 and the second sealing block 303; When the above arrangement is used, the raw materials for feed production are crushed, stirred and mixed, and then introduced into the extruder barrel 100, and then the first hollow shaft 101a is driven to rotate by the first driving device 101b. The rotation of the first hollow shaft 101a will drive the spiral blades and multiple spike rods 101c on its outer wall to rotate. The rotation of the spiral blades will continuously squeeze the mixed raw materials to make them heat up and gelatinize, and then start the water pump 202. The water pump 202 operates to extract the mixed solution of mildew inhibitor and water in the water tank 201 through the outlet pipe 201a (mildew inhibitor is a liquid that is harmless to organisms), and then pass it into the first hollow shaft 101a from the water inlet pipe 203 through the first connecting pipe 202a, and then the mixed solution is discharged from the end of the spike rod 101c into the gelatinized raw materials, and at the same time, boiler steam is introduced through the external steam pipe 304, and then the high-temperature steam enters the four groups of internal steam pipes 305 respectively under the action of the four-way sealing columns 307 inside the first sealing block 302 and the second sealing block 303, and finally the high-temperature steam Steam is sprayed into the raw material through the nozzle on the internal steam pipe 305 to accelerate the gelatinization of the raw material, and the first motor 306 is started. The output shaft of the first motor 306 rotates to drive the driving sprocket 306a to rotate, and the outer wall of the driving sprocket 306a is connected to the outer wall of the driven sprocket 307b on both sides through a chain. Therefore, when the driving sprocket 306a rotates, it will drive the driven sprockets 307b on both sides to rotate synchronously, and drive the four-way sealing column 307 to rotate synchronously under the action of the first rotating shaft 307a, so that the opening and closing of the four groups of internal steam pipes 305 can be adjusted, which is convenient for adjusting the opening and closing number of the internal steam pipes 305. Corresponding adjustments can be made according to the raw materials for feed production and the amount of raw materials in the extrusion barrel 100 to ensure gelatinization efficiency and effect and increase the scope of application. In order to ensure the pressure of high-temperature steam, the higher the pressure, the less water content of the steam. Therefore, by adding a mixed solution of mildew inhibitor and water into the raw material, the situation of insufficient moisture in the conditioning can be avoided, and the risk of mildew inside the extrusion equipment can be avoided.

[0045] Furthermore, the spiked rod 101c is connected to the interior of the first hollow shaft 101a and is provided with a water spray hole. The first sealing block 302 and the second sealing block 303 are symmetrically arranged. The pipe joint serves as a pipeline connection.
