[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.
[0018] like Figure 1 and Figure 2 As shown, a multi-layer paddle-type rice flavor enhancer mixing device includes: a shell 20, which is a hollow cylindrical shell with a conical bottom. A motor is installed on the top of the shell 20, and a feed pipe is also installed on the top of the shell 20. A discharge valve is installed on the bottom of the shell 20. The motor and the discharge valve are electrically connected to the corresponding power supply. This is existing technology and will not be described in detail here.
[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the impeller structure is disposed inside the cavity of the outer casing 20 for stirring inside the cavity of the outer casing 20. The impeller structure includes: a main shaft 30, a turbine 33, a ribbon impeller 34, and a turbopeller 35. The main shaft 30 is rotatably connected to the top of the cavity of the outer casing 20. A motor can drive the main shaft 30 to rotate. The turbine 33 is fixedly connected to the wall of the main shaft 30. The ribbon impeller 34 is fixedly connected to the wall of the turbine 33. The turbopeller 35 is fixedly connected to the top of the turbine 33.
[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the main shaft 30 is cylindrical, and the turbine 33 is located eccentrically on the main shaft 30. The turbine 33 is composed of symmetrical frustums, and the top and bottom planes of the turbine 33 have the same diameter as the main shaft 30. The outer edge of the turbine 33 is rounded. The ribbon propeller 34 is helical and located on the outer wall of the turbine 33. Multiple identical ribbon propellers 34 are evenly arranged in a ring on the outer wall of the turbine 33. The turboprop 35 is a rectangular plate, and multiple turboprops 35 are arranged in a ring on the top of the turbine 33. Each turboprop 35 is positioned at the top of the turbine 33. In the inclined position, the blade structure also includes a connecting rod 31, an upper ring 32, and a pumping propeller 36. The connecting rod 31 is symmetrically fixedly connected to the top of the main shaft 30, the upper ring 32 is fixedly connected to the wall of the symmetrical connecting rod 31, and the outer wall of the upper ring 32 can also be fixedly connected to the top wall of the ribbon propeller 34. The pumping propeller 36 is fixedly connected to the wall of the main shaft 30 below the turbine 33. The connecting rod 31 is a parallelogram-shaped rod, the upper ring 32 is a circular ring, the bottom end of the connecting rod 31 can be fixedly connected to the inner arc surface of the upper ring 32, and the pumping propeller 36 is a conical auger shape. In practical use, the desired flavoring agent is poured into the cavity of the outer shell 20 through the feed pipe at the top of the outer shell 20. Then, the power is turned on and rice is poured into the cavity of the outer shell 20 through the feed port. As the rice enters the cavity of the outer shell 20, it is soaked in the flavoring agent. With the motor turned on, the motor drives the main shaft 30 to rotate. The main shaft 30, when rotating, drives the connecting rod 31, the upper ring 32, the turbine 33, and the pumping propeller 36 to rotate synchronously within the cavity of the outer shell 20. The turbine 33, when rotating, drives the ribbon propeller 34 and the turboprop 35 to rotate synchronously. When the ribbon propeller 34 rotates, it agitates the flavor enhancer and rice in the cavity of the outer shell 20 to mix them. The pumping propeller 36 can guide and roll up the rice that has settled at the bottom of the cavity of the outer shell 20 when it rotates. The ribbon propeller 34 and the vortex propeller 35 will stir the cavity of the outer shell 20. At this time, when the ribbon propeller 34 rotates, it will form a vortex that converges towards the vortex propeller 35, and when the vortex propeller 35 rotates, it will form a vortex that expands outward towards the ribbon propeller 34. After the mixing is completed, the motor power is turned off and the discharge valve power is turned on to discharge the rice and flavor enhancer in the cavity of the outer shell 20. In summary, by setting up the blade structure, the convective vortex formed by the ribbon blade 34 and the turbo blade 35 during mixing can enhance the activity of rice in the cavity of the outer shell 20, while reducing the impact force on the rice through the inclined contact method. Furthermore, by using the pumping blade 36, rice can be prevented from settling in the cavity of the outer shell 20 and slowing down the mixing efficiency. Therefore, this solution can achieve both high mixing efficiency and reduce the probability of rice damage.
[0021] like Figure 2As shown, a guide ring 38 is fixedly connected to the inner wall of the cavity of the outer shell 20. The guide ring 38 is circular and the top of the guide ring 38 is inclined. Multiple guide rings 38 are evenly arranged inside the cavity of the outer shell 20. The cross-sectional dimension of each lower guide ring 38 is larger than that of the upper guide ring 38. A dividing blade 37 is fixedly connected to the connection between the cavity of the outer shell 20 and the feed pipe. The dividing blade 37 is a plate with a cross-shaped cross section. The position of the dividing blade 37 can be staggered from the upper ring 32. In actual use, when rice is poured in from the feed pipe, if there are clumps of rice, they will come into contact with the splitting blade 37. The splitting blade 37 will break up the clumps of rice. When the rice is being mixed inside the outer shell 20 cavity, the guide ring 38 will guide the rice towards the center of the outer shell 20 cavity through its inclined surface. In summary, by setting the splitting blade 37, clumped rice can be dispersed, preventing clumped rice from slowing down the mixing efficiency, while the guide ring 38 can always guide the rice towards the center of the cavity inside the outer shell 20, further enhancing the vitality of the rice.
[0022] Working principle: The required flavoring agent is poured into the cavity of the outer shell 20 through the feed pipe at the top of the outer shell 20. Then, the power is turned on and rice is poured into the cavity of the outer shell 20 through the feed port. As the rice enters the cavity of the outer shell 20, it will be soaked in the flavoring agent. When the motor is turned on, the motor will drive the main shaft 30 to rotate. When the main shaft 30 rotates, it can drive the connecting rod 31, the upper ring 32, the turbine 33 and the pumping paddle 36 to rotate synchronously in the cavity of the outer shell 20. When the turbine 33 rotates, it will drive the ribbon paddle 34 and the turbopaddle 35 to rotate synchronously. When the turbopaddle 35 and the ribbon paddle 34 rotate, they will stir the flavoring agent and rice in the cavity of the outer shell 20 to mix them. When the pumping paddle 36 rotates, it can guide and roll up the rice that has settled at the bottom of the cavity of the outer shell 20. After the mixing is completed, the motor power is turned off and the discharge valve power is turned on to discharge the rice and flavoring agent in the cavity of the outer shell 20.
