Description

Technical Field

[0001] This utility model relates to the field of rice flour processing technology, and in particular to a rice flour raw material mixing device. Background Technology

[0002] Rice flour is a powdered basic food ingredient made primarily from rice. It is widely used in the production of traditional rice products such as rice noodle rolls and rice vermicelli. During use, it needs to be mixed with water to revert to a uniform rice flour paste. Currently, to improve mixing efficiency and product quality, existing technologies generally employ a high-speed dispersing head within the mixing tank for mixing. The powder is usually manually added to the silo or mixing container. While this method can exert a strong shearing effect on the paste in the tank and effectively break up some particles, it is difficult to solve the problem of "bridging" and clumping of rice flour in the upstream silo or container due to factors such as moisture absorption and static electricity. Once the powder clumps in the silo, it not only easily clogs the discharge port but also enters the mixing tank in lumps of varying sizes. These pre-formed lumps quickly become wetted upon contact with liquid, forming a lubricating film with a stubborn structure. Even after being processed by a high-speed dispersing head, fine clumps of particles can still remain, ultimately affecting the overall uniformity and quality stability of the rice flour paste.

[0003] In existing technologies, powder is usually dispersed by adding a stirring device in the silo. However, such solutions often use independent drive systems, which leads to complex equipment structures, increased energy consumption, and difficulty in achieving process synergy between material dispersion and main stirring. More importantly, simple silo stirring often only solves local problems and fails to form an organic connection with subsequent mixing processes, resulting in the risk of secondary agglomeration of powder during the conveying and feeding stages, which restricts further improvement in mixing efficiency and finished product quality.

The mixing structure includes an annular groove formed on the inner wall of the mounting shell, an external gear ring rotatably disposed inside the annular groove, a gear meshing on one side of the external gear ring, a connecting shaft fixed inside the gear, a movable rod rotatably disposed on one side of the hopper, a first synchronous pulley fixed to the bottom end of the movable rod and the outer circular wall of the connecting shaft, a first synchronous belt meshing between two first synchronous pulleys, a rotating rod rotatably disposed inside the hopper, a plurality of horizontal shafts fixed to the outer circular wall of the rotating rod, a second synchronous pulley fixed to the top end of both the rotating rod and the movable rod, a second synchronous belt meshing between two second synchronous pulleys.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This rice slurry powder mixing device, through its mixing structure, allows the first motor to drive the stirring mechanism in the hopper via a synchronous transmission system to pre-disperse the rice slurry powder, preventing clumping from the source. Simultaneously, gear transmission drives the stirring blades in the mixing tank to rotate, achieving macroscopic mixing. This integrated design ensures synchronous pre-stirring in the hopper and rotation of the tank, significantly simplifies the overall structure, and improves power utilization efficiency. Pre-dispersion in the hopper ensures uniform powder feeding, rotational stirring achieves initial mixing, and the high-speed dispersing disc completes fine homogenization. This process effectively solves the quality problems caused by initial powder clumping in traditional mixing, significantly improving the uniformity and stability of the rice slurry.

[0022] Reference Figures 1-4 A rice flour powder mixing device includes a mixing tank 1, with a mounting shell 2 fixed to the top surface of the mixing tank 1. The mixing tank 1 communicates with the interior of the mounting shell 2. A hopper 3 is fixed inside the mounting shell 2. The mounting shell 2 has a mixing structure for mixing the rice flour powder. The mixing structure includes an annular groove 201 formed on the inner wall of the mounting shell 2. An external gear ring 202 is rotatably arranged inside the annular groove 201. A gear 203 meshes with one side of the external gear ring 202. A connecting shaft 204 is fixed inside the gear 203. A movable rod 205 is rotatably arranged on one side of the hopper 3. First synchronous pulleys 206 are fixed to the bottom end of the movable rod 205 and the outer circular wall of the connecting shaft 204. A first synchronous belt 207 meshes between 06 and 205. A rotating rod 208 is rotatably installed inside the hopper 3. Several horizontal shafts 209 are fixed on the outer circular wall of the rotating rod 208. A second synchronous wheel 210 is fixed at the top of both the rotating rod 208 and the movable rod 205. A second synchronous belt 211 meshes between the two second synchronous wheels 210. When the gear 203 rotates, it drives the movable rod 205 to rotate through the first synchronous wheel 206 and the first synchronous belt 207. When the movable rod 205 rotates, it drives the rotating rod 208 to rotate through the second synchronous wheel 210 and the second synchronous belt 211. When the rotating rod 208 rotates, it causes the several horizontal shafts 209 to disperse the powder in the hopper 3, preventing the powder from clumping and bridging.

[0023] In this embodiment, two fixing plates 301 are fixed on the top surface of the external gear ring 202, and rotating rods 302 are fixed on the bottom surface of the two fixing plates 301. Several stirring blades 303 are fixed on the outer circular wall surface of the rotating rods 302. The stirring blades 303 are evenly distributed along the length direction of the rotating rods 302. While the gear 203 drives the external gear ring 202 to rotate, the external gear ring 202 drives the two rotating rods 302 to revolve in the mixing tank 1, thereby performing macroscopic slow mixing.

[0024] In this embodiment, a first motor 4 is fixed to the top surface of the mounting shell 2. The output end of the first motor 4 passes through the top surface of the mounting shell 2 and is fixed to the top end of the connecting shaft 204. A second motor 401 is fixed to the top surface of the mounting shell 2. The output end of the second motor 401 passes through the top surface of the mounting shell 2 and is fixed to the mounting rod 402. Two dispersing discs 403 are fixed to the outer circular wall of the mounting rod 402. The two dispersing discs 403 are spaced apart. The dispersing discs 403 are existing technology. The first motor 4 is a geared motor and the second motor 401 is a servo motor. When the powder in the hopper 3 enters the mixing tank 1, the first motor 4 drives the gear 203 to rotate and disperse the powder in the hopper 3 to prevent blockage. At the same time, the rotating rod 302 performs macroscopic mixing and stirring through the stirring blade 303. The second motor 401 starts and drives the mounting rod 402 to rotate at high speed, so that the dispersing discs 403 quickly mix the powder and liquid.

[0025] In this embodiment, a protective shell 5 is fixed on the top surface of the hopper 3. The second synchronous pulley 210 and the second synchronous belt 211 are both located inside the protective shell 5. The protective shell 5 protects the second synchronous pulley 210 and the second synchronous belt 211 to prevent accidental contact by outsiders during operation.

[0026] In this embodiment, a feeding pipe 6 is fixedly connected to the bottom surface of the silo 3. The bottom end of the feeding pipe 6 is fixedly connected to the mixing tank 1. A conveying pipe 601 is fixedly connected to one side of the mixing tank 1. A butterfly valve (not shown in the figure) is fixed to one end of the feeding pipe 6. The silo 3 feeds material into the mixing tank 1 through the feeding pipe 6. The conveying pipe 601 can convey liquid into the mixing tank 1.

[0027] In this embodiment, a bracket 7 is fixed on the outer circular wall of the mixing tank 1, the inner bottom surface of the mixing tank 1 is funnel-shaped, and a discharge port 701 is opened on the bottom surface of the mixing tank 1. The discharge port 701 is controlled by a valve to discharge material.

[0028] Working principle: When the operator starts the first motor 4, its output shaft directly drives the connecting shaft 204 to rotate. The gear 203 fixed on the connecting shaft 204 rotates accordingly. This action generates two parallel power transmission paths, realizing the synchronous operation of multiple functions. The rotation of the gear 203 transmits power to the moving rod 205 through the two first synchronous pulleys 206 fixed on the connecting shaft 204 and the moving rod 205, and the first synchronous belt 207 meshing with them, causing it to start rotating. The rotation of the moving rod 205 then drives the rotating rod 208 to rotate inside the hopper 3 through the second synchronous pulley 210 and the second synchronous belt 211 at its top. Finally, several horizontal shafts 209 fixed on the rotating rod 208 continuously rotate, stir, and mechanically disperse the rice paste powder in the hopper 3. This process effectively destroys the physical structure of the powder before it is fed in, fundamentally preventing bridging and clumping, and ensuring that the powder can be conveyed downward in a loose and uniform state.

[0029] When gear 203 rotates, it drives the outer gear ring 202 that meshes with it to rotate along the annular groove 201. The two fixed plates 301 fixed on the top surface of the outer gear ring 202 also revolve, and drive the rotating rod 302 and stirring blade 303 below it to perform a large-scale, slow circular motion in the mixing tank 1. This revolving stirring creates a mild and dead-zone-free macroscopic environment for the initial mixing of powder and liquid.

[0030] When the pre-dispersed powder enters the mixing tank 1 through the feeding pipe 6, and the liquid is injected through the conveying pipe 601, the mixing process enters its core stage. At this time, the high-speed shearing system driven by the second motor 401 is activated. The second motor 401 directly drives the mounting rod 402 and the two spaced-apart dispersion discs 403 on it to rotate at high speed. The high-speed rotating dispersion discs 403 generate extremely strong shearing force and turbulence in local areas, which can instantly break up any tiny particles that may exist in the initially mixed slurry and achieve a high degree of homogeneous fusion of powder and liquid, thereby obtaining an extremely fine and uniform final rice slurry. Throughout the mixing process, the protective shell 5 located on top of the hopper 3 provides effective safety protection for the second synchronous pulley 210 and the second synchronous belt 211. After mixing is completed, the final product is discharged through the outlet 701 located at the funnel-shaped bottom of the mixing tank 1, thus completing a complete work cycle.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
