Description

Technical Field

[0001] The present invention relates to the technical field of rice noodle production, and particularly relates to a process and equipment for preparing semi-dry rice noodles. Background Art

[0002] Rice noodles, also known as rice threads or rice noodles, are long strip-shaped rice products made from rice; rice noodles can be used as a staple food or a snack, and are commonly consumed by people in several southern provinces.

[0003] In the processing technology of rice noodles, it is necessary to add water to rice flour to make rice paste, then extrude the rice paste into strip-shaped rice noodles through an extrusion device, then cook the rice noodles in heated water, and then dry the cooked rice noodles to make the finished rice noodles. In another production method, before extrusion molding of the rice paste made from rice flour, the rice paste is first cooked and then extruded to obtain cooked rice noodles. By adjusting the water content of the rice flour, semi-dry rice noodles can be made for the use of rice noodles, reducing the production time of rice noodles.

[0004] After the semi-dry rice noodles are made by equipment, the extruded rice noodles are extruded into the container below. After extruding a certain length, it is necessary to cut them to facilitate taking and cooking during eating; in the continuous production of rice noodles, when the cut rice noodles fall into the container, the rice noodles are prone to be disorderly when stacked, which is not convenient for taking. For example, the Chinese patent publication number CN218043640U in the prior art discloses a semi-dry and fresh wet rice noodle manufacturing device, which starts the driving motor through a motor controller. The driving motor drives the core shaft to rotate through a pulley group and a belt. When the core shaft rotates, it will drive the spiral blade to rotate. When the spiral blade rotates at a high speed, at this time, in cooperation with an external heating box, the stirring and forward feeding of the rice slurry can be realized, and at the same time, the full heating of the rice slurry can be fully realized, achieving the primary heating of the rice flour and rice noodles, so as to cook the rice slurry. The cooked rice slurry will enter the powder outlet and be discharged. Through the disclosed solution, when the rice noodles extruded by this type of device fall into the containing container, the arrangement order of the rice noodles cannot be guaranteed, and the rice noodles are arranged in a disorderly manner and are not convenient for taking. Summary of the Invention

[0005] The purpose of the present invention is to solve the above technical problems and provide a process and equipment for preparing semi-dry rice noodles.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions to be realized:

[0007] An apparatus for preparing semi-dry rice noodles, comprising a frame, an extrusion device is installed on the frame, a forming die is arranged at the end of the extrusion device, and a heating device for heating and cooking the rice paste inside the extrusion device is arranged on the outer wall of the extrusion device; the discharging end of the forming die faces downward and is provided with forming holes for extruding the rice noodles, a turntable is rotatably connected to the bottom of the frame, a receiving barrel is placed on the turntable, and the receiving barrel is located below the forming die to hold the extruded formed rice noodles;

[0008] A cutting device is arranged on one side of the receiving barrel. The cutting device comprises a cutting frame and a moving block. A cutting knife for cutting the rice noodles is fixedly connected to the moving block. The cutting knife is located between the forming die and the receiving barrel.

[0011] Further, a locking rod is provided at one end of the mounting rod away from the moving block. An avoidance groove is formed on the side of the extrusion rod close to the mounting rod, and a locking groove is formed on the side wall of the avoidance groove. The end of the locking rod extends into the avoidance groove and is fixedly connected with a locking tongue that is snapped into the locking groove. A top rod is fixedly connected to the support frame. When the extrusion rod approaches the support frame, the top rod presses against the locking rod to push the locking tongue on the locking rod away from the locking groove, so that the locking tongue releases the locking of the extrusion rod.

[0012] Further, a sliding groove is provided on the side of the mounting rod close to the extrusion rod.

The second spring is located on the side of the locking rod away from the top rod, and one end of the second spring is fixed on the mounting rod, and the other end of the second spring is fixed on the locking rod.

[0013] Further, a reset pin is fixedly connected to the cutting frame. The reset pin is located on the side of the extrusion rod away from the mounting rod. When the extrusion rod moves towards the cutting frame, the reset pin abuts against the extrusion rod, and the extrusion rod moves towards the mounting rod under the abutting pressure of the reset pin, so that the locking tongue is snapped into the locking groove to lock the extrusion rod.

[0014] Further, a blower cylinder is provided on the support frame. The blower cylinder is located between the forming die and the guiding cylinder. A blower is installed in the blower cylinder. The output shaft of the blower is fixedly connected with a fan blade, and the fan blade rotates to blow air on the rice noodles extruded from the forming die.

[0015] Specifically, a slide rail is provided on the cutting frame. The moving block is sleeved on the slide rail and is slidably matched with the slide rail.

[0016] Further, a circular groove matching the outer shape of the bottom of the material receiving bucket is provided on the turntable to position the material receiving bucket.

[0017] Further, the extrusion device includes a driving motor, an extrusion barrel and a rotating shaft arranged in the extrusion barrel. The rotating shaft is rotatably connected with the extrusion barrel. A first spiral blade and a second spiral blade are arranged on the rotating shaft. A feed inlet is provided on the extrusion barrel. The first spiral blade is located at one end of the rotating shaft close to the feed inlet, and the second spiral blade is located at one end of the rotating shaft away from the feed inlet. The pitch of the blades on the first spiral blade gradually decreases along the direction away from the feed inlet, and the pitch of the blades of the second spiral blade is arranged at equal intervals. The forming die is fixed at the discharge end of the extrusion barrel. The driving motor is installed on the frame, and the driving motor is in transmission connection with the rotating shaft to drive the rotating shaft to rotate, driving the first spiral blade and the second spiral blade to rotate, so as to extrude the rice paste to the discharge end of the extrusion barrel and extrude it from the forming die.

[0018] Further, the heating device includes a heating cylinder fixed to the outer side of the extrusion barrel. A heating chamber for containing heating water is formed between the inner cavity of the heating cylinder and the outer wall of the extrusion barrel. A heating pipe is arranged in the heating chamber and is used to heat the heating water in the heating chamber. The heating chamber is located outside the relative position of the second spiral blade in the extrusion barrel.

[0019] Further, anti-slip patterns are arranged on the side surface of the extrusion rod close to the material receiving barrel, and anti-slip patterns are arranged on the outer wall of the material receiving barrel at the position opposite to the extrusion rod.

[0020] A process for preparing semi-dry rice noodles using the above-mentioned equipment for preparing semi-dry rice noodles includes the following steps:

[0021] 1. Pour the stirred rice noodle raw material rice paste into the feed port of the extrusion barrel, start the driving motor to drive the rotating shaft to rotate, and compress and convey the rice paste by driving the first spiral blade and the second spiral blade to rotate;

[0022] 2. Connect the heating pipe to electricity to heat the water in the heating cylinder, and heat and cook the rice paste in the extrusion barrel through the heating water;

[0023] 3. Convey the rice paste to the forming die through the rotation of the first spiral blade and the second spiral blade to extrude and form linear formed rice noodles;

[0024] 4. The formed rice noodles are extruded and fall, and the cutting knife cuts the rice noodles into set-length segments. After cutting, the material receiving barrel is driven to rotate, so that the rice noodles fall into the material receiving barrel and are coiled in the material receiving barrel to complete the production of rice noodles.

[0025] The process and equipment for preparing semi-dry rice noodles provided by the present invention have the following beneficial effects: The cutting knife is driven by the linear driving device to approach the rice noodles and cut the rice noodles. At the same time, the mounting rod connected to the moving block is driven to move to one side of the material receiving barrel, and the compression spring pushes out the extrusion rod so that the extrusion rod fits against the side wall of the material receiving barrel; after the rice noodles are cut, the linear driving device drives the moving block to move away from the material receiving barrel, drives the cutting knife to move away from the rice noodles, and thus drives the extrusion rod to move towards the cutting rack. The extrusion rod fits against the side wall of the material receiving barrel during the movement, so that the material receiving barrel rotates through the frictional force. After cutting, there is a certain distance between the lower end of the newly made rice noodles and the stored material in the material receiving barrel. The newly made rice noodles continue to be conveyed downward under continuous extrusion. When the lower end of the rice noodles touches the material in the material receiving barrel, due to the rotation of the material receiving barrel, the lower end of the rice noodles rotates with the material receiving barrel, while the rice noodles continue to descend, so that the rice noodles are coiled in the material receiving barrel, thus keeping the rice noodles neat.

[0036] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0038] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly. The connection described can be a direct connection or an indirect connection.

[0039] As Figures 1-8 shown, a device for preparing semi-dry rice noodles includes a frame 1. An extrusion device 2 is installed on the frame 1. A forming die 3 is provided at the end of the extrusion device 2. A heating device 4 for heating and cooking the rice paste inside the extrusion device 2 is provided on the outer wall of the extrusion device 2. The discharge end of the forming die 3 faces downward and is provided with forming holes 31 for extruding rice noodles. The bottom of the frame 1 is rotatably connected to a turntable 11. A receiving bucket 5 is placed on the turntable 11. The receiving bucket 5 is located below the forming die 3 to hold the extruded formed rice noodles 10.

[0040] A cutting device 6 is provided on one side of the receiving bucket 5. The cutting device 6 includes a cutting frame 61 and a moving block 62. A cutting knife 63 for cutting the rice noodles is fixedly connected to the moving block 62. The cutting knife 63 is located between the forming die 3 and the receiving bucket 5. A linear driving device 64 is installed on the cutting frame 61. The driving end of the linear driving device 64 is connected to the moving block 62 to drive the moving block 62 to move, thereby driving the cutting knife 63 to move to cut the rice noodles. A transmission device 7 is fixedly connected to the moving block 62. The transmission device 7 includes a mounting rod 71 fixed to the moving block 62. A pressing rod 72 is rotatably connected to the mounting rod 71. A compression spring 73 is provided in the mounting rod 71. The compression spring 73 abuts against the side of the pressing rod 72 away from the receiving bucket 5 to provide an elastic force to push the pressing rod 72 towards the receiving bucket 5. When the linear driving device 64 drives the cutting knife 63 to move towards the cutting frame 61, it drives the pressing rod 72 to move towards the cutting frame 61 and drives the receiving bucket 5 to rotate.

[0041] In this embodiment, a connecting frame 66 is fixedly connected to the moving block 62, the cutting knife is fixed on the connecting frame 66, a connecting rod 67 is fixedly connected to the lower end of the connecting frame 66, the connecting rod 67 extends downward, and the mounting rod 71 is fixedly connected to the connecting rod 67. Among them, the linear driving device 64 adopts one of a cylinder or a hydraulic cylinder, and the moving block 62 is fixed to the piston rod end of the cylinder or the hydraulic cylinder. By driving the moving block 62 to reciprocate through the cylinder or the hydraulic cylinder, the quick cutting of the rice noodles can be realized.

[0042] With the above technical solution, during the production process of the rice noodles, the linear driving device 64 drives the cutting knife 63 to approach the rice noodles and cut the rice noodles, and at the same time drives the mounting rod 71 connected to the moving block 62 to move to one side of the receiving barrel 5, and the compression spring 73 pushes out the extrusion rod 72 so that the extrusion rod 72 fits against the side wall of the receiving barrel 5; after the rice noodles are cut, the linear driving device 64 drives the moving block 62 to move away from the receiving barrel 5, driving the cutting knife 63 to move away from the rice noodles (that is, towards the cutting frame 61), thereby driving the extrusion rod 72 to move towards the cutting frame 61. The extrusion rod 72 fits against the side wall of the receiving barrel 5 during the movement, so that the receiving barrel 5 rotates through the frictional force. After cutting, there is a certain distance between the lower end of the newly produced rice noodles and the stored materials in the receiving barrel 5. The newly produced rice noodles continue to be conveyed downward under continuous extrusion. When the lower end of the rice noodles touches the materials in the receiving barrel 5, due to the rotation of the receiving barrel 5, the lower end of the rice noodles rotates with the receiving barrel 5, while the rice noodles continue to descend, so that the rice noodles 10 are coiled in the receiving barrel 5, thus keeping the rice noodles neat and avoiding the random tilting and disorderly stacking of the rice noodles in the receiving barrel 5 when the receiving barrel 5 is stationary and the rice noodles freely descend and touch the objects in the receiving barrel 5.

[0043] It should be noted that if the receiving barrel 5 is stationary, when the rice noodles are descending and the rice noodles touch the materials in the receiving barrel 5, the rice noodles randomly bend and tilt to the side, and the rice noodles randomly bend and stack in the receiving barrel 5, making the rice noodles disorderly and inconvenient for subsequent use; while when the receiving barrel 5 is rotating, when the lower end of the rice noodles touches the internal materials of the receiving barrel 5, the rotation of the receiving barrel 5 causes the lower end of the rice noodles to move with the receiving barrel 5, and the subsequent rice noodles 10 are inclined in the inclined direction at the time of contact. After the receiving barrel 5 stops rotating, the rice noodles 10 continue to coil in the initial coiling and bending direction, so that the coiling directions are the same. Specifically, at the start of production, when the rice noodles are extruded from the forming die 3, a cutting operation can be performed to cut the unruly rice noodles just extruded, and at the same time drive the receiving barrel 5 to rotate, so as to facilitate the coiling of the rice noodles in the receiving barrel 5.

[0044] Specifically, a support frame 12 is fixedly connected to the frame 1. A guiding cylinder 8 is fixedly connected to the support frame 12. A baffle 81 is fixedly connected to the lower end of the guiding cylinder 8. The baffle 81 is semi-circular and located on the side of the guiding cylinder 8 away from the cutting knife 63. The guiding cylinder 8 and the material receiving barrel 5 are eccentrically arranged. The guiding cylinder 8 is used to constrain and guide the rice noodles when the rice noodles pass through the guiding cylinder 8. The cutting edge of the cutting knife 63 is set as an arc structure matching the inner wall of the baffle 81. When cutting the rice noodles, the cutting knife 63 approaches the baffle 81 and jointly squeezes the rice noodles passing through the guiding cylinder 8 with the baffle 81. By arranging the guiding cylinder 8 to constrain the rice noodles, the extruded formed rice noodles neatly pass through the guiding cylinder 8 and fall into the material receiving barrel 5, preventing the rice noodles from spreading and falling into the material receiving barrel 5, making the rice noodles more neatly arranged. At the same time, the rice noodles are constrained in the guiding cylinder 8 by the guiding cylinder 8, facilitating the cutting knife 63 to cut the rice noodles.

[0045] Specifically, a locking rod 74 is arranged at one end of the mounting rod 71 away from the moving block 62. An avoidance groove 721 is formed on the side of the pressing rod 72 close to the mounting rod 71. A locking groove 722 is formed on the side wall of the avoidance groove 721. The end of the locking rod 74 extends into the avoidance groove and is fixedly connected with a locking tongue 75 that is snapped into the locking groove 722. A top rod 13 is fixedly connected to the support frame 12. When the pressing rod 72 approaches the support frame 12, the top rod 13 presses on the locking rod 74 to push the locking tongue 75 on the locking rod 74 away from the locking groove 722, so that the locking tongue 75 releases the locking of the pressing rod 72. The pressing rod 72 is locked by the locking tongue 75 snapping into the locking groove 722 and is limited on one side of the mounting rod 71. When the linear driving device 64 drives the cutting knife 63 to approach the rice noodles, the mounting rod 71 synchronously moves to one side of the material receiving barrel 5. At this time, the pressing rod 72 is limited in the mounting rod 71 and has no contact with the material receiving barrel 5, and cannot drive the material receiving barrel 5 to rotate. When the cutting knife 63 cuts the rice noodles, the mounting rod 71 moves towards the top rod 13. The top rod 13 presses the locking rod 74 to make the locking tongue 75 release the locking of the pressing rod 72. The pressing rod 72 pops out and fits on the side wall of the material receiving barrel 5. When the pressing rod 72 moves away from the rice noodles, it drives the material receiving barrel 5 to rotate. It is realized that when the cutting knife 63 moves towards the rice noodles, the material receiving barrel 5 is not driven, and when the cutting knife 63 moves away from the rice noodles, the pressing rod 72 fits on the outer wall of the material receiving barrel 5 to drive the material receiving barrel 5 to rotate, so as to guide the initial inclination direction of the cut rice noodles so that the rice noodles are coiled in the material receiving barrel 5, and the driving direction is the same each time, so as to keep the winding direction of the rice noodle bundle in the material receiving barrel 5 around the inner wall of the material receiving barrel 5 consistent and not affect normal cutting.

[0046] Specifically, a chute 711 is provided on one side of the mounting rod 71 close to the extrusion rod 72. One end of the locking rod 74 is located in the chute 711 and is in sliding fit with the chute 711. A second spring 76 is provided on the mounting rod 71. The second spring 76 is located on the side of the locking rod 74 away from the ejector rod 13. One end of the second spring 76 is fixed to the mounting rod 71, and the other end of the second spring 76 is fixed to the locking rod 74. By providing the second spring 76 to provide elastic force, the locking tongue 75 on the locking rod 74 is kept inserted into the locking groove 722. When the ejector rod 13 presses the locking rod 74, the second spring 76 contracts, and the locking tongue 75 moves away from the locking groove 722 to disengage from the locking groove 722. The extrusion rod 72 pops out away from the mounting rod 71 under the elastic force of the compression spring 73. After the extrusion rod 72 pops out, it abuts against the material receiving bucket 5 and fits against the outer wall of the material receiving bucket 5.

[0047] Specifically, a reset pin 14 is fixedly connected to the cutting frame 61. The reset pin 14 is located on the side of the extrusion rod 72 away from the mounting rod 71. The reset pin 14 abuts against the extrusion rod 72 when the extrusion rod 72 moves towards the cutting frame 61. The extrusion rod 72 moves towards the mounting rod 71 under the abutting and pressing of the reset pin 14, so that the locking tongue 75 is inserted into the locking groove 722 to lock the extrusion rod 72. When the extrusion rod 72 retracts, it abuts against the reset pin 14. Since the end of the extrusion rod 72 close to the material receiving bucket 5 is in a popped-out state after unlocking, during the process of the extrusion rod 72 moving towards the cutting frame 61, the reset pin 14 contacts and presses the extrusion rod 72, causing the extrusion rod 72 to move towards the mounting rod 71. The locking groove 722 on the extrusion rod 72 approaches the locking tongue 75. The extrusion rod 72 continues to retract, causing the locking tongue 75 to be inserted into the locking groove 722, thereby locking the extrusion rod 72 and the mounting rod 71, and further preventing the extrusion rod 72 from touching the material receiving bucket 5 when the moving block 62 is pushed towards the material receiving bucket 5 by the linear driving device 64, realizing the unidirectional driving of the material receiving bucket 5 to rotate. A guiding inclined surface is provided on the side of the locking tongue 75 away from the mounting rod 71, so that when the locking tongue 75 is inserted into the extrusion rod 72, the guiding inclined surface contacts the extrusion rod 72 and the locking tongue 75 is moved and inserted into the locking groove 722 by the inclined surface extrusion.

[0048] Specifically, a flared structure is provided at the upper end of the guiding cylinder 8. Through the guiding of the flared structure with a larger opening, it is convenient for the rice noodles to penetrate into the guiding cylinder 8 during opening.

[0049] Specifically, a blower cylinder 9 is provided on the support frame 12. The blower cylinder 9 is located between the forming die 3 and the guiding cylinder 8. A blower 91 is installed in the blower cylinder 9. The output shaft of the blower 91 is fixedly connected with a fan blade 92. The fan blade 92 rotates to blow air on the rice noodles extruded from the forming die 3. By driving the fan blade 92 to rotate by the blower 91 to blow air on the rice noodles, the surface of the rice noodles is dried, and the effect of adjusting the semi-dry state of the rice noodles is achieved.

[0050] Specifically, the cutting frame is provided with a slide rail 65, and the moving block 62 is sleeved on the slide rail 65 and slidably cooperates with the slide rail 65. The slide rail 65 cooperates with the moving block 62, so that the moving block 62 slides along the slide rail 65, thereby improving the stability of the movement of the moving block 62, and maintaining the consistency of the moving position of the cutting knife 63 each time during the process of cutting the rice noodles.

[0051] Specifically, the rotating disk 11 is provided with a circular groove 15 matching the bottom shape of the receiving barrel 5 to position the receiving barrel 5. When the receiving barrel 5 is placed on the rotating disk 11, the bottom of the receiving barrel 5 is placed in the circular groove 15, and the receiving barrel 5 is limited by the circular groove 15, so as to ensure that the receiving barrel 5 is placed in the same position each time, and avoid the position of the receiving barrel 5 from being offset; when taking out the receiving barrel 5, one side of the receiving barrel 5 can be raised and pulled out. Specifically, the receiving barrel 5 is provided with a handle, and when the receiving barrel 5 is full, the handle is lifted, so that the receiving barrel 5 can be pulled out to replace the receiving barrel 5.

[0052] Specifically, the extrusion device 2 includes a driving motor 21, an extrusion barrel 22 and a rotating shaft 23 arranged in the extrusion barrel 22, the rotating shaft 23 is rotatably connected to the extrusion barrel 22, a first spiral blade 24 and a second spiral blade 25 are arranged on the rotating shaft 23, a feed port 26 is arranged on the extrusion barrel 22, the first spiral blade 24 is located at the end of the rotating shaft 23 close to the feed port 26, the second spiral blade 25 is located at the end of the rotating shaft 23 away from the feed port 26, the blade pitch on the first spiral blade 24 gradually decreases in the direction away from the feed port 26, and the blade pitch of the second spiral blade 25 is equidistantly arranged; the molding die 3 is fixed at the discharge end of the extrusion barrel 22, the driving motor 21 is installed on the frame 1, and the driving motor 21 is transmission-connected with the rotating shaft 23 to drive the rotating shaft 23 to rotate and drive the first spiral blade 24 and the second spiral blade 25 to rotate, thereby squeezing the rice paste to the discharge end of the extrusion barrel 22 and extruding it from the molding die 3. By arranging a first spiral blade 24 with a gradually decreasing pitch on the rotating shaft 23, the rice paste is squeezed during the rotating conveying process of the first spiral blade 24, so that the rice paste is squeezed densely, and the second spiral blade 25 continues to convey the rice paste, and then conveys the rice paste to the forming mold 3 to extrude and form linear rice noodles.

[0053] Specifically, the heating device 4 includes a heating cylinder 41 fixed on the outer side of the extrusion barrel 22. A heating chamber for containing heating water is formed between the inner cavity of the heating cylinder 41 and the outer wall of the extrusion barrel 22. A heating pipe 42 is arranged in the heating chamber. The heating pipe 42 is used to heat the heating water in the heating chamber. The heating chamber is located outside the relative position of the second spiral blade 25 in the extrusion barrel 22. The heating water in the heating chamber is heated by the heating pipe 42, and the heating water heats the extrusion barrel 22, thereby heating and ripening the rice paste in the extrusion barrel 22, so that the rice paste is bonded together after ripening.

[0054] Specifically, anti-slip lines are arranged on the side surface of the extrusion rod 72 close to the material receiving barrel 5, and anti-slip lines are arranged on the outer wall of the material receiving barrel 5 at the position opposite to the extrusion rod 72. When the extrusion rod 72 is in close contact with the material receiving barrel 5, the anti-slip lines of the two are abutted against each other, thereby increasing the friction between them and facilitating the rotation of the material receiving barrel 5 driven by the movement of the extrusion rod 72.

[0055] On the other hand, a process for preparing semi-dry rice noodles uses the above-mentioned equipment for preparing semi-dry rice noodles and includes the following steps:

[0056] 1. Pour the stirred rice noodle raw material rice paste into the feed port 26 of the extrusion barrel 22, start the driving motor 21 to drive the rotating shaft 23 to rotate, and compress and convey the rice paste by driving the first spiral blade 24 and the second spiral blade 25 to rotate;

[0057] 2. Connect the heating pipe 42 to electricity to heat the water in the heating cylinder 41, and heat and ripen the rice paste in the extrusion barrel 22 through the heating water;

[0058] 3. Convey the rice paste to the forming die 3 through the rotation of the first spiral blade 24 and the second spiral blade 25 to extrude into linear formed rice noodles;

[0059] 4. The formed rice noodles are extruded and fall, and the cutting knife 63 cuts the rice noodles into set-length segments. After cutting, the material receiving barrel 5 is driven to rotate, so that the rice noodles fall into the material receiving barrel 5 and are coiled in the material receiving barrel 5 to complete the production of rice noodles.

[0060] Working principle of a device for preparing semi-dry rice noodles in the present invention: During operation, the well-stirred rice paste is poured into the feed port 26 of the extrusion barrel 22. The driving motor 21 drives the rotating shaft 23 to rotate, thereby causing the first spiral blade 24 and the second spiral blade 25 to rotate and compress and convey the rice paste to the forming die 3. During the conveying process of the rice paste through the extrusion barrel 22, the rice paste is heated and cooked by the heating device 4. The cooked rice paste is extruded into linear formed rice noodles through the forming die 3. The extruded formed rice noodles pass through the guiding cylinder 8 and fall downward into the receiving barrel 5. The linear driving device 64 drives the moving block 62 to move towards the receiving barrel 5, thereby driving the cutting knife 63 to move towards the guiding cylinder 8. After the cutting knife 63 abuts against the baffle 81, the rice noodles passing through the guiding cylinder 8 are cut off. While the cutting knife 63 moves towards the guiding cylinder 8, the moving block 62 drives the mounting rod 71 to move to the side of the receiving barrel 5 and the ejector rod 13 abuts against the locking rod 74. The ejector rod 13 presses the locking rod 74, causing the lock tongue 75 on the locking rod to disengage from the locking groove 722, releasing the locking of the extrusion rod 72. Under the action of the compression spring 73, the end of the extrusion rod 72 close to the ejector rod 13 pops out towards the receiving barrel 5. After the extrusion rod 72 pops out, it fits on the outer wall of the receiving barrel 5. After the cutting knife 63 cuts off the rice noodles, the linear driving device 64 drives the moving block 62 to move away from the receiving barrel 5, thereby driving the extrusion rod 72 to move away from the receiving barrel 5. When the extrusion rod 72 fits on the outer wall of the receiving barrel 5 and moves, it drives the receiving barrel 5 to rotate through friction. At the same time, the rice noodles fall into the receiving barrel 5, and the lower end of the rice noodles contacts the rotating receiving barrel 5. The lower end of the rice noodles 10 moves along with the receiving barrel 5, and the subsequent rice noodles are inclined in the inclined direction of the rice noodles 10 at the time of contact. After the receiving barrel 5 stops rotating, the rice noodles 10 continue to coil in the initial coiling and bending direction in the receiving barrel 5, so that the coiling direction of the rice noodles after each cutting is the same. The extrusion rod 72 continues to move away from the receiving barrel 5. The extrusion rod 72 contacts the reset pin 14. The reset pin 14 presses the extrusion rod 72, causing the extrusion rod 72 to move towards the mounting rod 71. The locking groove 722 on the extrusion rod 72 approaches the lock tongue 75. The extrusion rod 72 continues to retract, causing the lock tongue 75 to snap into the locking groove 722, thereby locking the extrusion rod 72 and the mounting rod 71 and completing the reset of the extrusion rod 72.
