Description

Technical Field

[0001] This utility model relates to the technical field of processing equipment for instant grain noodles, specifically a twin-screw extrusion cutter device for anti-sticking instant grain noodles. Background Technology

[0002] Instant multigrain noodles contain grains such as buckwheat, oats, corn, and black beans, providing B vitamins, dietary fiber, and minerals. They have a low glycemic index, which helps stabilize blood sugar and increase satiety. Compared with traditional refined noodles, they have a higher dietary fiber content, which can promote digestion and prevent constipation. Because instant multigrain noodles require a high degree of mixing of multigrain ingredients, twin-screw extrusion is often used in actual production to achieve a high degree of mixing of multigrain noodles. After extrusion with a custom die at the end of the twin screw, the noodles are cut and shaped by a rotary cutter. Therefore, twin-screw extruders, as processing equipment with mixing function, are one of the common production equipment for instant multigrain noodles.

[0003] In existing technologies, the production and processing of multigrain instant noodles first requires mixing multigrain powder and wheat flour according to the formula design, controlling the proportion of multigrain to balance fiber content and formability. Then, the raw materials are premixed with water and sent to a modulator. The temperature and humidity are regulated by steam to promote starch pregelatinization. Through the synergistic action of twin screws, the material forms a high-pressure chamber under the push of the meshing screws. The screw assembly includes a conveying section, a shearing section, and a melting section. The temperature is controlled in stages. The material expands instantly under high pressure and high temperature, forming a porous structure. Finally, the expanded melt is extruded through a customized mold, such as a noodle die, and cut into segments with the help of rotating cutters. The segments are then sent to a multi-layer belt dryer for drying, completing the production process.

[0004] While the aforementioned existing technologies have significant beneficial effects, they still have shortcomings:

[0005] In the above production process, the combination of twin-screw extrusion and customized export mold forms the mixing and rapid production of mixed grain instant noodles. However, when the puffed melt of the noodles is extruded through the die, the noodles themselves are not dried and are moist. When the noodles are cut into segments by the rotating cutter, the noodles are easy to stick to the structure of the cutter itself. This makes it impossible for the rotating cutter to stably cut the noodles in subsequent segment cutting, affecting production efficiency. To address this, a twin-screw extrusion cutter device for anti-sticking mixed grain instant noodles is proposed. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a twin-screw extrusion cutter device for anti-sticking mixed grain instant noodles. The production process is formed by connecting the port frame with the discharge port of the twin-screw extruder. The surface of the rotary cutter adopts an inclined surface design, which can form an angled blade during the rotary cutting process, reducing the contact area with the noodles and thus reducing the occurrence of sticking. At the same time, high-pressure air blowing with the assistance of the air blowing pipe prevents sticking.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a twin-screw extrusion cutter device for anti-sticking instant grain noodles, comprising an extrusion cutter end, an extrusion die frame engaged on one side of the inner wall of the extrusion cutter end, the extrusion cutter end including a port frame, threaded grooves formed around the inner wall of the port frame, a connecting frame fixed to the top of the port frame, a pneumatic pipe passing through the middle of the top of the connecting frame, a motor frame fixed to the outer wall of the other end of the connecting frame, a rotary cutting post fixed to the inner wall of the other end of the connecting frame, a motor shaft rotatably connected to the axis of the rotary cutting post, a pneumatic chamber formed around the inner perimeter of the rotary cutting post, an air blowing pipe distributed at one end of the pneumatic chamber, a rotary cutting shaft fixed to one end of the motor shaft, and rotary cutting blades fixed to the outer walls on both sides of the rotary cutting shaft.

[0008] Preferably, the outer wall of the rotary cutter is inclined, and the rotary cutter forms a rotating structure with the rotary cutting pile through the rotary cutting shaft and the motor shaft.

[0009] Preferably, the motor shaft is rotatably coupled to the connecting frame via the motor frame, and the rotary cutting pile is fixedly connected to the port frame via the connecting frame.

[0010] Preferably, one side of the rotary cutting blade is in contact with the outer wall of the extrusion die holder, and the rotary cutting blades are symmetrically distributed along both sides of the rotary cutting axis.

[0011] Preferably, the air pressure connector is connected to the air blowing pipe through the air pressure chamber, and the air blowing pipe is inclined along both sides of the end of the rotary cutting pile.

[0012] Preferably, the extrusion die holder includes a die plate base, with a port frame attached to the outer walls of the die plate base, limiting grooves formed at both ends of the die plate base, an extrusion die fixed to one side of the die plate base, and a forming opening formed inside the extrusion die.

[0013] Preferably, the die plate seat is fastened to one side of the inner wall of the port frame through a limiting groove, and the die plate seat is fixedly connected to the extrusion die.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model connects the port frame with the discharge port of a twin-screw extruder to form a production process. With the rotation of the rotary cutter of the port frame, the instant noodles formed by the extrusion die can be quickly rotary cut and discharged. The surface of the rotary cutter is designed with an inclined surface, which can form an angled blade during the rotary cutting process, reducing the contact area with the noodles and thus reducing the occurrence of adhesion. At the same time, with the assistance of high-pressure air blowing through the air blowing pipe, if adhesion occurs, it can be treated by intermittent air blowing to avoid adhesion, thereby avoiding the impact of subsequent rotary cutting and improving production and processing efficiency.

[0016] 2. The rotary cutter of this twin-screw extrusion cutter device maintains stable rotary cutting and output during noodle extrusion by adhering to the surface of the extrusion die, thereby generating sufficient shearing force. The inclination angle of the air blowing pipe is aligned with the angle of the rotary cutter, which can stably provide high-pressure air blowing assistance to the blade surface.

[0017] 3. The extrusion die of this twin-screw extrusion cutter device can be stably connected to the end frame through the limiting grooves opened at both ends of the die plate seat. At the same time, the die plate seat can also be replaced at any time during disassembly, which is convenient for adjustment according to different production needs of different surface shapes.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4This embodiment of a twin-screw extrusion cutter device for anti-sticking instant grain noodles includes an extrusion cutter end 1. An extrusion die frame 2 is engaged on one side of the inner wall of the extrusion cutter end 1. The extrusion cutter end 1 includes a port frame 101. Threaded grooves 102 are formed around the inner wall of the port frame 101. A connecting frame 103 is fixed to the top of the port frame 101. An air pressure pipe 104 passes through the middle of the top of the connecting frame 103. A motor frame 105 is fixed to the outer wall of the other end of the connecting frame 103. A rotary cutting post 106 is fixed to the inner wall of the other end of the connecting frame 103. A motor shaft 107 is rotatably connected to the axis of the rotary cutting post 106. An air pressure chamber 108 is formed around the inside of the rotary cutting post 106. An air blowing pipe 109 is distributed at one end of the air pressure chamber 108. A rotary cutting shaft 110 is fixed to one end of the motor shaft 107. Rotary cutting blades 111 are fixed to the outer walls on both sides of the rotary cutting shaft 110.

[0026] like Figure 1-4As shown, the twin-screw extrusion cutter device of this utility model is similar in structure to the existing twin-screw extrusion cutter device. The main improvement of this utility model is that the production process is formed by connecting the port frame 101 with the discharge port of the twin-screw extruder. The surface of the rotary cutter 111 is designed with an inclined surface, which can form an angled blade during the rotary cutting process, reducing the contact area with the noodles and thus reducing the occurrence of adhesion. At the same time, the high-pressure air blowing assisted by the air blowing pipe 109 prevents adhesion. In this utility model, both the port frame 101 and the motor frame 105 are existing... With this technology, when using this twin-screw extrusion cutter device, the matching extrusion die holder 2 can be rotated to fit the desired instant noodle shape. Then, the die plate seat 201 of the extrusion die holder 2 is fastened to the inner wall of the port holder 101. At this time, the entire port holder 101 is connected to the outlet of the twin-screw extruder along the threaded groove 102. Production can then proceed. When the grain noodles are extruded by the twin-screw extruder, they are shaped by the extrusion die holder 2. Subsequently, the motor frame 105 is started, driving the motor shaft 107 and the integrated rotary cutting shaft 110 to rotate. The rotating rotary cutting shaft 110 drives the rotary cutting blades 111 on both sides to cut the instant noodles at the forming outlet at a uniform speed. Simultaneously, the air pressure pipe 104 is connected to a booster pump, blowing air pressure into the air pressure chamber 108 through the air pressure pipe 104. This air pressure is then discharged through the air blowing pipe 109, which is connected to one end of the air pressure chamber 108, intermittently blowing high-pressure air onto the rotary cutting blades 111 during the rotary cutting process. This causes the instant noodle material on the surface of the rotary cutting blades 111 to be quickly blown off, thus completing the production process. This twin-screw extrusion cutting device is connected to the twin screws via the port frame 101. The extruder's outlet docks to form the production process. In conjunction with the rotation of the rotary cutter 111 on the port frame 101, the instant noodles formed by the extrusion die 203 can be quickly rotary cut and discharged. The surface of the rotary cutter 111 is designed with an inclined surface, which can form an angled blade during the rotary cutting process, reducing the contact area with the noodles and thus reducing the occurrence of adhesion. At the same time, with the assistance of high-pressure air blowing through the air pipe 109, when adhesion occurs, intermittent air blowing can be used to prevent adhesion, thereby avoiding the impact of subsequent rotary cutting and improving production efficiency.

[0027] The aforementioned rotary cutter 111 adheres to the surface of the extrusion die 203, thereby maintaining stable rotary cutting and forming sufficient shearing force during noodle extrusion. The inclination angle of the air blowing pipe 109 is aligned with the angle of the rotary cutter 111, which can stably provide high-pressure air blowing assistance to the blade surface.

[0028] like Figure 2-4As shown, the extrusion die holder 2 includes a die plate base 201. A port frame 101 is attached to the outer walls of the die plate base 201. Limiting grooves 202 are formed at both ends of the die plate base 201. An extrusion die 203 is fixed to one side of the die plate base 201. A forming opening 204 is formed inside the extrusion die 203. During installation, the extrusion die holder 2 can be placed into the inner wall of the port frame 101, while simultaneously ensuring the limiting grooves 202 at both ends of the die plate base 201 are in place. Aligning with the rails on both sides of the inner wall of the port frame 101, the die plate seat 201 is securely installed. After the port frame 101 is screwed tightly to the discharge port of the extruder, the die plate seat 201 is also secured to the inner wall of the port frame 101, thus completing its installation and use. The extrusion die 203 can be stably connected to the port frame 101 through the limiting grooves 202 opened at both ends of the die plate seat 201. At the same time, the die plate seat 201 can also be replaced at any time during disassembly, making it convenient to adjust according to different surface production requirements.

[0029] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
