A low-temperature high-expansion food extrusion device includes:
[0025] The base 1 has a voltage regulator 12 fixedly mounted on the upper surface of the base 1, and a melt homogenizing tube 13 is fixedly connected to one side surface of the voltage regulator 12. A homogenizing screw 23 is provided inside the melt homogenizing tube 13, and a control component is provided at one end of the homogenizing screw 23. A molding chamber 16 is also provided on the upper surface of the base 1, and a cutting disc 15 is provided inside the molding chamber 16. A storage box 17 is provided below the cutting disc 15. A discharge plate 14 is provided at the end of the melt homogenizing tube 13, and the discharge plate 14 is located inside the molding chamber 16. A kneading chamber 10 is fixedly mounted on the upper surface of the voltage regulator 12, and a kneading inner tube 27 is provided inside the kneading chamber 10. The kneading inner tube 27 is connected to the melt The melting and homogenizing tubes 13 are connected through a feeding pipe 11, and an anti-sticking mechanism is further provided inside the kneading inner tube 27. A transfer tube 9 is fixedly installed on the upper surface of the kneading bin 10, and a feeding tube 7 is further provided on one side surface of the transfer tube 9. A feeding threaded rod 20 is provided inside the feeding tube 7, and a driving motor 19 for driving the feeding threaded rod 20 is further provided at one end of the feeding tube 7. A discharge connecting tube 8 is connected to the upper surface of the feeding tube 7, and a storage box 3 is fixedly installed on one side surface of the discharge connecting tube 8. A peek window 4 is provided on one side surface of the storage box 3, and a support frame 2 is fixedly installed on the bottom surface of the peek window 4. A loading assembly is further provided on one side surface of the storage box 3;
[0026] During use, the material enters the storage box 3 through the feeding mechanism, enters the feeding pipe 7 through the unloading connecting pipe 8, and moves to one end under the drive of the feeding threaded rod 20, and finally enters the kneading bin 10 through the transfer pipe 9 for pressurization and kneading. After entering the melt homogenization pipe 13 through the feeding pipe 11, the material loses the pressure effect, begins to melt and expands, and finally leaves the melt homogenization pipe 13 through the discharge plate 14, and is divided and formed by the cutting disk 15 to complete the overall production.
[0027] The anti-sticking mechanism includes: a kneading rod 21, which is located inside the kneading inner tube 27, and one end of the kneading rod 21 is provided with a control motor for driving it to rotate, a plurality of connecting rings 24 are provided on the surface of the kneading rod 21, a plurality of stirring branches 26 are provided on the surface of the connecting ring 24, and a receiving groove 25 is provided on both sides of the connecting ring 24. A plurality of scraping rings 28 are also provided on the surface of the kneading rod 21, a scraping ring 28 is provided between every two connecting rings 24, and each scraping ring 28 is connected by a connecting rod 29, and the end of the connecting rod 29 is connected to the end connecting rod 30, a rotatable rotating disk 22 is provided on one side surface of the kneading inner tube 27, and the connecting rod 29 passes through the surface of the rotating disk 22 and is connected to the end connecting rod 30, and a telescopic motor 31 is also provided on the surface of the rotating disk 22, and the end of the output shaft of the telescopic motor 31 is connected to one side surface of the end connecting rod 30;
[0028] The anti-sticking mechanism primarily prevents material from adhering to the inner wall of the kneading inner tube 27 through the rotation of the kneading rod 21 and the reciprocating motion of the scraper ring 28. When the control motor is started, the kneading rod 21 begins to rotate, and the multiple connecting rings 24 and the stirring branches 26 on its surface rotate accordingly, thoroughly mixing and kneading the material. At the same time, the scraper ring 28 between each two connecting rings 24 is connected to the telescopic motor 31 on the rotating disk 22 via the connecting rod 29 and the end connecting rod 30. The periodic telescopic motion of the telescopic motor 31 drives the scraper ring 28 to scrape the inner wall of the kneading inner tube 27 back and forth, effectively removing adhered material and ensuring the kneading effect and cleanliness of the equipment.
[0029] The feeding assembly includes: a feeding slide 5, which is fixedly mounted on the upper surface of the storage box 3. A lifting screw 32 is also provided on one side surface of the support frame 2. A servo motor is provided on the bottom surface of the lifting screw 32 to drive it to rotate. The surface of the lifting screw 32 is engaged with a feeding platform 6. A horizontal hole is opened at the center of the feeding platform 6, and a baffle 18 is provided inside the horizontal hole.
[0030] The feeding component realizes automatic feeding of materials through the lifting screw 32 driven by the servo motor. After the servo motor is started, it drives the lifting screw 32 to rotate. Due to the meshing relationship between the lifting screw 32 and the surface of the feeding platform 6, the feeding platform 6 is gradually lifted, and the material slides from the feeding slope 5 to the feeding platform 6. As the feeding platform rises, the material is transported to the storage box 3. At the same time, the baffle 18 at the center of the feeding platform 6 plays a role in blocking the material during the lifting process, ensuring that the material can enter the storage box in an orderly and uniform manner.
[0031] The control assembly includes: a movable ring plate 33, which is sleeved on the surface of the homogenizing screw 23 to form threads on the surface of the homogenizing screw 23. A small motor 35 is provided on one side of the movable ring plate 33. A hidden groove for accommodating the small motor 35 is provided on the upper surface of the homogenizing screw 23. A retractable shielding plate 34 is provided on the upper surface of the hidden groove;
[0032] The control component drives the movable ring plate 33 to extend and retract on the surface of the homogenizing screw 23 through a small motor 35, thereby controlling the pitch of the threads on the surface of the homogenizing screw 23, so that the user can control the pitch of the threads on the surface of the homogenizing screw 23 according to the characteristics of the material. When the small motor 35 drives the movable ring plate 33 to rise, the threads on the surface are squeezed, and the spacing between the threads becomes smaller, and vice versa. The appropriate spacing can be adjusted according to the material of the food, so that the material is subjected to sufficient squeezing force, thereby achieving an ideal puffing effect.
[0033] The working principle of the low-temperature, high-expansion food extrusion device provided by the utility model is as follows:
[0034] When in use, the staff starts the feeding assembly to realize automatic feeding of materials through the lifting screw 32 driven by the servo motor. After the servo motor is started, the lifting screw 32 is driven to rotate. Due to the meshing relationship between the lifting screw 32 and the surface of the feeding platform 6, the feeding platform 6 is gradually lifted, and the material slides from the feeding slope 5 to the feeding platform 6. As the feeding platform rises, the material is transported to the storage box 3. At the same time, the baffle 18 at the center of the feeding platform 6 plays a role in blocking the material during the lifting process, ensuring that the material can enter the storage box in an orderly and uniform manner.
[0035] After the material enters the storage box 3 through the feeding mechanism, it enters the feeding pipe 7 through the unloading connecting pipe 8 and moves to one end under the drive of the feeding threaded rod 20. Finally, it enters the kneading chamber 10 through the transfer pipe 9 for pressurization and kneading. After entering the melting and homogenizing pipe 13 through the feeding pipe 11, the material loses the pressure effect, begins to melt and expands, and finally exits the melting and homogenizing pipe 13 through the discharge plate 14 and is divided and formed by the cutting disk 15 to complete the overall production.
[0036] The anti-sticking mechanism primarily functions when the material enters the kneading chamber 10. The rotation of the kneading rod 21 and the reciprocating motion of the scraper ring 28 prevent the material from adhering to the inner wall of the kneading inner tube 27. When the control motor is activated, the kneading rod 21 begins to rotate, and the multiple connecting rings 24 and the stirring branches 26 on its surface rotate accordingly, thoroughly mixing and kneading the material. Simultaneously, the scraper ring 28 between each two connecting rings 24 is connected to the telescopic motor 31 on the rotating disk 22 via a connecting rod 29 and an end connecting rod 30. The periodic telescopic motion of the telescopic motor 31 drives the scraper ring 28 to scrape back and forth against the inner wall of the kneading inner tube 27, effectively removing adhered material and ensuring kneading effectiveness and equipment cleanliness.
[0037] The control component drives the movable ring plate 33 to extend and retract on the surface of the homogenizing screw 23 through a small motor 35, thereby controlling the pitch of the threads on the surface of the homogenizing screw 23, so that the user can control the pitch of the threads on the surface of the homogenizing screw 23 according to the characteristics of the material. When the small motor 35 drives the movable ring plate 33 to rise, the threads on the surface are squeezed, and the spacing between the threads becomes smaller, and vice versa. The appropriate spacing can be adjusted according to the material of the food, so that the material is subjected to sufficient squeezing force, thereby achieving an ideal puffing effect.
