Description

Technical Field

[0001] This invention relates to the field of rice crust production technology, specifically to an extruded rice crust production equipment and a method for producing soybean rice crust. Background Technology

[0002] Soybean rice crust is indeed a crispy and delicious snack. It is mainly made of soybeans, often combined with rice, millet or corn flour, etc. Nowadays, after the soybean rice crust is produced, different spices are often sprayed on the surface of the rice crust to achieve different flavors.

[0003] Chinese patent CN212814223U discloses a seasoning dispenser for making rice crusts, including a storage cylinder, a cylindrical conveying component connected to the bottom of the storage cylinder, a discharge component with an opening at the bottom of the conveying component away from the storage cylinder, and a fixing bracket for fixing the conveying component. The central axis of the conveying component is either horizontal or inclined. A rotating shaft is rotatably mounted on the conveying component along its central axis. A reduction motor for driving the rotating shaft is mounted at the end of the rotating shaft near the storage cylinder. Spiral blades are mounted on the rotating shaft. This invention ensures uniform seasoning distribution by using the spiral blades to push the seasoning at a constant speed from the discharge component.

[0004] The above-mentioned technology still has certain drawbacks in practical use. For example, when using it, the powdered fragrance needs to be poured into the storage tank, which can easily cause the fragrance to spill when pouring the powdered fragrance. Some fragrances contain irritating ingredients, which can cause workers to sneeze after inhaling them. In addition, the above-mentioned technical solution cannot achieve quantitative spraying of fragrance, thus resulting in certain limitations. Summary of the Invention

[0020] A method for producing soybean rice crusts, using the aforementioned puffed rice crust production equipment.

[0021] Compared with the prior art, the present invention provides an equipment for producing puffed rice crust and a method for producing soybean rice crust, which has the following beneficial effects:

[0022] 1. In this invention, during the feeding process, the Roots pump is turned on and the dual-shaft motor is controlled to run at medium speed. At this time, the feeding drive unit operates, thereby driving the connecting pipe to open. The connecting pipe then connects to the external powdered spice box. The Roots pump then transports the powdered spice into the mixing drum, thus completing the feeding of the powdered spice. When the dual-shaft motor is running at medium speed, the mixing shaft is also driven to run at medium speed. At this time, the mixing shaft can agitate the powdered spice entering the mixing drum, thereby ensuring thorough mixing of the spices. This achieves convenient feeding of powdered spice while avoiding the problem of dust overflow during feeding, thus avoiding environmental pollution and injury to workers. Furthermore, the mixing shaft, rotating at medium speed, can also agitate the powdered spice, further enhancing its practicality.

[0023] 2. In this invention, during material feeding, the dual-shaft motor is controlled to operate at low speed. At this time, the feeding drive stops operating, and the locking device releases its lock on the reciprocating device. The stirring shaft is also in a low-speed operating state. After the feeding drive stops operating, the connecting pipe is closed, preventing the powdered fragrance from entering the mixing drum. After the locking device releases its lock on the reciprocating device, the reciprocating device starts operating. The reciprocating device then drives the feeding pipe to move up and down repeatedly. The powdered fragrance that has been mixed in the mixing drum is then transported to the conveying mechanism through the feeding pipe and then conveyed away by the conveying mechanism. During this process, the stirring shaft continuously agitates the powdered fragrance in the mixing drum, allowing the powdered fragrance to quickly enter the feeding pipe. Furthermore, the reciprocating movement of the feeding pipe enables quantitative feeding of the material, thereby further improving practicality and ease of use.

[0024] 3. In this invention, the locking electric push rod can lock the state of the feeding drive component when the connecting pipe is opened by the feeding drive component, so that the connecting pipe can be in a stable open state. In this way, with the cooperation of the Roots pump, a stable feeding effect can be achieved, further improving the ease of use. Attached Figure Description

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes an extruded rice crust production equipment and a method for producing soybean rice crust.

[0044] Example 1: Please refer to Figures 1-11 A puffed rice crust production equipment includes a mixing drum 1, a conveying mechanism 2 at the bottom of the mixing drum 1, a mixing shaft 5 inside the mixing drum 1, a dual-shaft motor 3 and a Roots pump 4 on the mixing drum 1. The dual-shaft motor 3 is used to drive the mixing shaft 5 to rotate, and the Roots pump 4 is used to transport powdered spices into the mixing drum 1.

[0045] The mixing drum 1 is equipped with a feeding mechanism 6 and a discharging mechanism 7. The feeding mechanism 6 includes a connecting pipe 61, a feeding drive component 62 and a locking electric push rod 63. The connecting pipe 61 is connected to the Roots pump 4. The feeding drive component 62 is used to switch the connecting pipe 61 on and off. The locking electric push rod 63 is used to lock the feeding drive component 62.

[0046] The feeding mechanism 7 includes a feeding pipe 71, a locking member 72, and a reciprocating member 73. The feeding pipe 71 is connected to the mixing drum 1 and the conveying mechanism 2. The feeding pipe 71 is used to convey the powdered spices in the mixing drum 1 to the conveying mechanism 2. The locking member 72 is used to lock the reciprocating member 73. The reciprocating member 73 is used to drive the feeding pipe 71 to move up and down reciprocally.

[0047] The dual-axis motor 3 includes two modes: medium speed and low speed.

[0048] During the medium-speed stage, the feeding drive 62 drives the connecting pipe 61 to open, and the locking electric push rod 63 locks the feeding drive 62. At this time, the stirring shaft 5 rotates at medium speed. At the same time, the Roots pump 4 delivers the external powdered spices into the stirring drum 1, and the locking part 72 locks the reciprocating part 73.

[0049] During the low-speed phase, the feeding drive 62 drives the connecting pipe 61 to close. At this time, the stirring shaft 5 rotates at low speed. Simultaneously, the Roots pump 4 stops feeding, and the locking component 72 releases the lock on the reciprocating component 73. Then, the reciprocating component 73 drives the discharge pipe 71 to move back and forth, conveying the powdered spices in the stirring drum 1 to the conveying mechanism 2.

[0050] During feeding, the Roots pump 4 is turned on, and the dual-shaft motor 3 is controlled to run at medium speed. The medium-speed operation of the dual-shaft motor 3 drives the stirring shaft 5 to run at medium speed. At this time, the locking component 72 locks the reciprocating component 73, preventing the reciprocating component 73 from driving the discharge pipe 71 to move, thus preventing feeding. Simultaneously, the feeding drive component 62 is driven by the medium-speed operation of the dual-shaft motor 3, which drives the connecting pipe 61 to open, connecting the connecting pipe 61 to the Roots pump 4. Then, the locking electric push rod 63 locks the feeding drive component 62, ensuring that the connecting pipe 61 remains stably open. Afterward, the Roots pump 4 delivers the external feed to the mixing drum 1. After the powdered spices enter the mixing drum 1, the stirring shaft 5 stirs the powdered spices, ensuring thorough mixing. After mixing is complete, the dual-shaft motor 3 is controlled to run at low speed. Then, the locking electric push rod 63 releases the lock on the feeding drive 62, and the feeding drive 62 drives the connecting pipe 61 to close, stopping the feeding. During this period, the locking part 72 releases the lock on the reciprocating part 73, and the reciprocating part 73 operates, thereby driving the feeding pipe 71 to move up and down reciprocally. When the feeding pipe 71 moves upward, the powdered spices in the mixing drum 1 enter the conveying mechanism 2 through the feeding pipe 71. When the feeding pipe 71 moves downward, the feeding of the powdered spices stops. After the powdered spices enter the conveying mechanism 2, the conveying mechanism 2 conveys the powdered spices. This achieves the goal of making it convenient for users to feed the spices, while avoiding the problem of dust overflowing during feeding. It can also stir the spices, so that they can be fully mixed, and can automatically perform quantitative feeding, thereby greatly improving practicality and ease of use.

[0051] Example 2: See Figures 1-11Unlike Embodiment 1 described above, the two ends of the connecting pipe 61 are respectively connected to an inlet pipe 611, an outlet pipe 612, and a fan plate 613. The inlet pipe 611 is connected to an external powdered spice container, and the outlet pipe 612 is connected to the Roots pump 4. The fan plate 613 is rotatably connected to the inner side of the connecting pipe 61, and the outer side of the fan plate 613 is fixedly connected to a worm gear 614 via a rotating shaft. The outer side of the worm gear 614 is meshed with a worm 615, which is rotatably connected to the connecting pipe 61. One end of the worm 615 is fixedly connected to a drive gear 616. The feeding drive component 62 The device includes a drive wheel 621, which is fixedly connected to the output shaft of the dual-axis motor 3. A driven wheel 622 is connected to the inner side of the drive wheel 621 via a transmission belt. A feeding tray 623 is coaxially fixedly connected to the outer side of the driven wheel 622. Several circumferentially distributed sliding protrusions 624 are slidably connected to the feeding tray 623. A feeding spring 625 is fixedly connected to the inner side of the sliding protrusions 624. The end of the feeding spring 625 away from the sliding protrusions 624 is fixedly connected to the feeding tray 623. A roller 626 is provided on the inner side of the sliding protrusions 624. The feeding drive component 62 also includes a mounting plate 627, which is mounted on the mixing drum 1. A rack 628 is slidably connected to the mounting plate 627. A limit spring 629 is fixedly connected to the outer side of the rack 628. The limit spring 629 is fixedly connected to the mounting plate 627. When the rack 628 moves, it can drive the drive gear 616 to rotate. A locking electric push rod 63 is mounted on the mounting plate 627. A locking hole 631 is opened on the rack 628. After the connecting pipe 61 is opened, the output shaft of the locking electric push rod 63 can be inserted into the locking hole 631.

[0052] When the dual-axis motor 3 is running at medium speed, the drive wheel 621 rotates synchronously. The rotation of the drive wheel 621 drives the driven wheel 622 to rotate via the transmission belt. The rotation of the driven wheel 622 drives the loading plate 623 to rotate. Since the dual-axis motor 3 is running at medium speed at this time, when the loading plate 623 rotates, the centrifugal force on its outer sliding convex plate 624 is greater than the elastic force of the loading spring 625. At this time, under the action of centrifugal force, the sliding convex plate 624 gradually moves to the outside of the loading plate 623. The movement of the sliding convex plate 624 drives the roller 626 to move. The roller 626 gradually contacts the rack 628 and drives the rack 628 to move towards the drive gear 616. The movement of the rack 628 compresses the limiting spring 629 and drives the drive gear 616 to rotate. The rotation of the drive gear 616 drives the worm 615 to rotate. The rotation of the worm 615 drives the worm wheel 614 to rotate. The rotation of the worm wheel 614 drives the fan plate 613 to flip. At this time, the connecting pipe When 61 is opened, powdered spices from the outside enter the connecting pipe 61 through the feed pipe 611, then enter the discharge pipe 612, and then enter the mixing drum 1 through the Roots pump 4. After the rack 628 moves to its maximum position, the locking electric push rod 63 is turned, thereby inserting the output shaft into the locking hole 631 on the rack 628. At this time, the position of the rack 628 is locked, so that the fan plate 613 can be opened stably. When the dual-shaft motor 3 is running at low speed, the locking electric push rod 63 is reset, and the rack 628 is released from locking. At this time, because the centrifugal force on the feeding plate 623 is small, the sliding convex plate 624 is retracted under the influence of the spring force of the feeding spring 625. At the same time, the rack 628 is reset by the limiting spring 629. During this process, the rack 628 drives the drive gear 616 to reverse. Similarly, the fan plate 613 in the connecting pipe 61 is driven to reset. At this time, the connecting pipe 61 is closed, so that feeding can no longer be carried out.

[0053] It should be noted that the locking electric push rod 63 is electrically connected to an external PLC controller. A pressure sensor is installed on the mounting plate 627, distributed along the stroke of the rack 628. A pressure sensor is also installed on the output shaft of the locking electric push rod 63. Both pressure sensors are electrically connected to the external PLC controller. When the rack 628 moves to its maximum position and drives the connecting pipe 61 to open, the pressure sensor on the mounting plate 627 can detect this and send a signal back to the PLC controller. The PLC controller then controls the locking electric push rod 63 to operate, thereby locking the rack 628. When the rack 628 resets, it exerts pressure on the output shaft of the locking electric push rod 63. The pressure sensor on the locking electric push rod 63 can detect this and send a signal back to the PLC controller. Similarly, the PLC controller controls the output shaft of the locking electric push rod 63 to reset.

[0054] Example 3, see Figures 1-11Unlike Embodiment 2 described above, the reciprocating component 73 includes a central gear 731 and a right-angle plate 738. The central gear 731 is fixedly connected to the output shaft of the dual-axis motor 3. Symmetrically distributed planetary gears 732 mesh with the outer side of the central gear 731. A connecting frame 733 is provided on the outer side of the planetary gears 732, and the connecting frame 733 is rotatably connected to the output shaft of the dual-axis motor 3. A gear ring 734 meshes with the outer side of the planetary gears 732, and a shaft bracket 735 is fixedly connected to the outer side of the gear ring 734. A fixing plate 736 is rotatably connected to the outer side of the shaft bracket 735. The fixing plate 736 is mounted on the stirring drum 1. A cam 737 is fixedly connected to the shaft bracket 735. A right-angle plate 738 is fixedly connected to the stirring drum 1. A protruding rod 739 is slidably connected to the right-angle plate 738. A connecting spring 7310 is fixedly connected to the bottom of the protruding rod 739. The end of the connecting spring 7310 away from the protruding rod 739 is fixedly connected to the right-angle plate 738. A connecting plate 739 passes through the right-angle plate 738 and is fixedly connected to it. 311, the connecting plate 7311 is fixedly connected to the feed tube 71. When the cam 737 rotates, it can contact the cam 739. The feed tube 71 has several feed holes 711 on its round table. The locking member 72 includes a feed plate 721, which is fixedly connected to the output shaft of the dual-axis motor 3. Several circumferentially distributed movable cams 722 are slidably connected to the feed plate 721. A feed spring 723 is fixedly connected to the inner side of the movable cam 722. The feed spring 723 is away from the movable cam 722. One end is fixedly connected to the feeding plate 721. A round wheel 729 is rotatably connected to the movable convex plate 722. The locking member 72 also includes a fixing frame 724 and an insertion hole 728. The fixing frame 724 is installed on the mixing drum 1. A bracket 725 is slidably connected to the fixing frame 724. A return spring 726 is fixedly connected to the bracket 725. The return spring 726 is fixedly connected to the fixing frame 724. An insertion rod 727 is fixedly connected to the bracket 725. The insertion hole 729 is circumferentially opened on the gear ring 734.

[0055] When the dual-axis motor 3 is running at medium speed, both the feed plate 721 and the central gear 731 rotate. Because the dual-axis motor 3 rotates at a relatively high speed at this time, the centrifugal force on the moving cam 722 on the feed plate 721 is large, allowing the moving cam 722 to overcome the elastic force of the feed spring 723. The moving cam 722 then moves outward, driving the wheel 728 to gradually move outward from the feed plate 721. The movement of the wheel 728 causes the bracket 725 to move upward, which in turn compresses the reset spring 726 and drives the insertion rod 727 to advance. Insertion hole 729, at this time the gear ring 734 is fixed. Since the gear ring 734 is fixed at this time, when the central gear 731 rotates, the planetary gear 732 on the outside of the central gear 731 is driven to move along the inner circumference of the gear ring 734. At this time, the feed tube 71 cannot move. When the dual-shaft motor 3 is running at low speed, the centrifugal force on the moving cam 722 is less than the elastic force of the feed spring 723. At this time, the moving cam 722 is reset by the feed spring 723, and at the same time, it loses the lifting force of the moving cam 722. The bracket 725 will also be reset under the action of the reset spring 726. As the bracket 725 resets, the insertion rod 727 separates from the insertion hole 729 on the gear ring 734. At this point, the gear ring 734 is unlocked and no longer restricted. When the central gear 731 rotates, the planetary gear 732 on its outer side drives the gear ring 734 to rotate. The rotation of the gear ring 734 drives the shaft bracket 735 to rotate, which in turn drives the cam 737 to rotate. The cam 737 gradually contacts the cam rod 739 and drives the cam rod 739 to move downward. The downward movement of the cam rod 739 compresses the connecting spring 7310 and drives the connecting plate 7311. The connecting plate 7311 moves downward, causing the feeding pipe 71 to move downward. After the feeding pipe 71 moves downward, its feeding hole 711 is removed from the mixing drum 1. At this time, the feeding pipe 71 can no longer feed the powdered fragrance in the mixing drum 1. Then, the cam 737 separates from the cam 739. At this time, the connecting spring 7310 drives the cam 739 to reset. Then the feeding pipe 71 moves upward. After the feeding pipe 71 moves upward, the feeding hole 711 moves into the mixing drum 1. At this time, the powdered fragrance in the mixing drum 1 enters the feeding pipe 71 through the feeding hole 711 and is then discharged through the feeding pipe 71.

[0056] It should be noted that when the feed pipe 71 moves to its maximum position, its upper end will not contact the stirring shaft 5, and its lower end will not separate from the conveying mechanism 2.

[0057] Example 4, see Figures 1-11Unlike the above embodiment 3, the top of the stirring shaft 5 is fixedly connected to a driven bevel gear 51, and the outer side of the driven bevel gear 51 is meshed with a driving bevel gear 52. The driving bevel gear 52 is fixedly connected to the output shaft of the dual-shaft motor 3. The conveying mechanism 2 includes a conveying pipe 21, which is provided with a feed inlet 22 and a discharge outlet 25. The discharge pipe 71 is inserted into the inner side of the feed inlet 22. A drive motor 23 is provided on the outer side of the conveying pipe 21. The output shaft of the drive motor 23 passes through the conveying pipe 21 and is fixedly connected to a spiral shaft 24. The Roots pump 4 is provided with a pipe structure that communicates with the stirring drum 1.

[0058] When the dual-shaft motor 3 is running at medium speed, it drives the active bevel gear 52 to rotate, which in turn drives the driven bevel gear 51 to rotate. The driven bevel gear 51 then drives the stirring shaft 5 to rotate, which in turn drives the stirring shaft 5 to rotate. The stirring shaft 5 rotates to quickly stir the powdered spices in the mixing drum 1, thus ensuring thorough mixing. Similarly, when the dual-shaft motor 3 is running at low speed, the stirring shaft 5 rotates at a slower speed. At this time, the stirring shaft 5 can "drive" the powdered spices in the mixing drum 1 into the feeding pipe 71. After the packaged spices enter the conveying pipe 21, the drive motor 23 is started. The drive motor 23 rotates to drive the spiral shaft 24 to rotate, which then conveys the powdered spices until they are discharged from the outlet 25.
