Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other. Example

[0018] A rice noodle extrusion machine, such as Figure 1-3As shown, the system includes an extrusion chamber 1; each extrusion chamber 1 is rotatably equipped with an auger 2; a hopper 3 is connected to the upper part of one end of the extrusion chamber 1; a perforated plate 5 and a buffer chamber 6 are detachably installed at the end of the extrusion chamber 1 away from the hopper 3; the perforated plate 5 has several filter holes; and a discharge pipe 7 is connected to one end of the buffer chamber 6. There are two extrusion chambers 1, and the lower end of the hopper 3 is connected to both extrusion chambers 1; the walls of the two extrusion chambers 1 located below the hopper 3 are connected by a connecting plate 4; a flange is fixed to the outer wall of one end of each of the two extrusion chambers 1, and a flange is also fixed to the outer wall of one end of the buffer chamber 6; the perforated plate 5 is sandwiched between the two flanges. The function of the connecting plate 4 is to seal the gap between the two extrusion chambers to prevent material from falling through the gap.

[0019] The extrusion machine used for rice noodle processing adopts a double spiral extrusion, which makes the extrusion more stable. By adding a perforated plate 5, the resistance can be increased, allowing rice noodles that are not fully cooked to be cooked a second time, resulting in rice noodles with better toughness, more uniform thickness, and less breakage.

[0020] Specifically, one end of each of the two auger shafts 13 passes through the extrusion chamber 1 and is fitted with meshing gears 8; one end of one shaft 13 is fitted with a pulley 9. A pulley is connected to the output shaft of the motor 12. During operation, the motor 12 is turned on, driving the pulley 9 and one of the shafts 13 to rotate via a synchronous belt, and driving the other shaft 13 to rotate in the opposite direction under the action of the two meshing gears 8. In another embodiment, the pulley 9 and synchronous belt can be replaced with a sprocket and a transmission chain.

[0021] Specifically, a bearing housing 15 is installed at one end of the rotating shaft 13 that passes through the extrusion chamber 1; an end cap 16 is installed at one end of the bearing housing 15; a first bearing 17 and a second bearing 18 are installed inside the bearing housing 15; a shoulder 24 is provided on the rotating shaft 13; and mounting holes for installing the first bearing 17 and the second bearing 18 are opened at corresponding positions in the inner cavity of the bearing housing 15. The rotating shaft 13 is supported by the first bearing 17 and the second bearing 18.

[0022] Specifically, in order to improve the stability of the rotation of the shaft 13, a thrust bearing 19 is also installed in the bearing housing 15; a limiting ring 25 is fitted on the shaft 13; the limiting ring 25 is installed between the first bearing 17 and the thrust bearing 19; and several through holes 26 for disassembling the thrust bearing 19 are opened on the bearing housing 15.

[0023] Specifically, to improve sealing performance, a wing plate 14 is fixed to the outer wall of the extrusion chamber 1; a pad 20 is sandwiched between the bearing seat 15 and the wing plate 14; the bearing seat 15, the wing plate 14, and the pad 20 are connected by screws; and the inner sides of the end cover 16 and the pad 20 are provided with receiving grooves for placing the sealing ring 22.

[0024] Specifically, the side wall of the bearing housing 15 has an oil injection hole 21, and a plug is installed in the oil injection hole 21.

[0025] Specifically, a cooling pipe 10 is installed above the extrusion chamber 1, and one end of the cooling pipe 10 is connected to a water source and a pumping device. During operation, cooling water is introduced into the cooling pipe 10 and sprayed onto the extrusion chamber 1 below to cool it.

[0026] Specifically, to further improve the cooling effect, a base plate 23 is fixed to the bottom of the two extrusion chambers 1. Since there is a gap between the two extrusion chambers 1, some of the sprayed water can accumulate in the space enclosed by the opposite sides of the two extrusion chambers 1 and the base plate 23. As new sprayed water continuously flows out, water continuously overflows from the upper edge of the extrusion chamber 1, cooling the outer wall of the extrusion chamber 1.

[0027] Specifically, a dispersion cover 11 is provided above the two extrusion chambers 1; the dispersion cover 11 is in the shape of a truncated pyramid, and its surface has several drainage holes. The dispersion cover 11 can disperse the water flow from the cooling pipe 10.

[0028] The working principle of this utility model: During operation, motor 12 is turned on. Motor 12 drives pulley 9 and one of the rotating shafts 13 to rotate via a synchronous belt, and drives the other rotating shaft 13 to rotate in the opposite direction under the action of two meshing gears 8. The steamed material is controlled to enter hopper 3 and then into two extrusion chambers 1. The auger 2 rotates, pushing the material towards the other end of the extrusion chamber 1 and being extruded through the holes on the perforated plate 5. After extrusion, the material enters buffer chamber 6 and is finally discharged through discharge pipe 7. The next device after the extruder is the filament extruder. The material discharged from discharge pipe 7 enters the hopper of the filament extruder.

[0029] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
