[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0020] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0021] The rice bran cooling and extracting device comprises a cooling box 1, wherein a rice bran separation cylinder 2 is rotatably installed inside the cooling box 1, gear plates 3 are fixedly sleeved on both ends of the outer wall of the rice bran separation cylinder 2, a feeding pipe 4 is rotatably installed in the middle of one end of the rice bran separation cylinder 2 through a first rotating shaft, and a discharge pipe 5 is rotatably installed in the middle of the other end of the rice bran separation cylinder 2 through a second rotating shaft, and a valve is occasionally installed on the discharge pipe 5. A rice collecting box 10 is provided at the bottom of one side of the cooling box 1, and a rice bran collecting box 11 is provided at the bottom of the rice collecting box 10. A suction fan 12 is fixedly installed on one side, and the output end of the suction fan 12 is fixedly penetrated by the interior of the rice bran collecting box 11. The rice rolls in the rice bran separation drum 2, which can help the rice to contact with the cooling air more quickly, thereby achieving a rapid cooling effect. Rapid cooling helps prevent the rice from absorbing too much moisture, thereby reducing the risks brought by moisture and improving the quality of rice processing. The rice rolling in the rice bran separation drum 2 can filter the rice bran through the mesh holes on the surface of the rice bran separation drum 2, and the rice bran can also be filtered during the cooling process.

[0022] In this embodiment, the outer walls of the two gear plates 3 are meshed with driving gears 7, and the two driving gears 7 are connected by a connecting rod 8. The two driving gears 7 are rotatably connected to the inner wall of the cooling box 1. A motor 9 is fixedly installed on one side of the cooling box 1. The output end of the motor 9 passes through the cooling box 1 and is fixedly connected to the middle part of one end of the driving gear 7. The cooperation of the driving gear 7, the connecting rod 8 and the motor 9 drives the gear plate 3 to rotate, and further drives the rice bran separation drum 2 to rotate.

[0023] In this embodiment, a lower hopper 14 is fixedly passed through the bottom end of the cooling box 1, and a connecting pipe 13 is fixedly connected to the bottom end of the lower hopper 14. One end of the connecting pipe 13 is fixedly passed through the other side of the rice bran collecting box 11. The setting of the lower hopper 14 and the connecting pipe 13 serves to guide the rice bran to the inside of the rice bran collecting box 11.

[0024] In this embodiment, a filter screen 15 is slidably connected to one side of the inner wall of the rice bran collecting box 11 close to the suction fan 12. One end of the filter screen 15 is movably penetrated with the front of the rice bran collecting box 11. A handle 16 is fixedly installed in the middle of the front of the filter screen 15. The setting of the filter screen 15 plays a role in filtering impurities, preventing impurities from entering the interior of the suction fan 12 and causing damage to the suction fan 12. In addition, the sliding setting of the filter screen 15 allows it to be disassembled and cleaned separately when too many impurities adhere to the surface of the filter screen 15.

[0025] In this embodiment, a top plate 6 is snap-fitted to the top of the cooling box 1 . The snap-fitting installation of the top plate 6 facilitates subsequent disassembly, thereby facilitating centralized cleaning of the interior of the cooling box 1 .

[0026] Working principle: When in use, the rice that needs to be cooled after processing is first guided to the rice bran separation drum 2 inside the cooling box 1 through the feeding pipe 4 for cooling. At this time, the driving motor 9 is running, and the two gear plates 3 are driven to rotate synchronously under the connection of the connecting rod 8, which further drives the rice bran separation drum 2 to rotate. The rice rolls in the rice bran separation drum 2, so that it contacts the cooling air in the rice bran separation drum 2 more quickly, thereby accelerating the entire cooling process. At the same time, the suction fan 12 is driven to operate to generate negative pressure, so that the air carrying rice bran passes through the rice bran separation drum 2 for filtration, and then enters the rice bran collecting box 11 for centralized collection through the discharge hopper 14 and the connecting pipe 13. The provided filter screen 15 filters the air and intercepts impurities such as rice bran on the filter screen 15. The subsequent pulling handle 16 can clean the filter screen 15 centrally. After completion, the valve on the discharge pipe 5 is opened, so that the cooled and bran-removed rice is discharged through the discharge pipe 5 to the rice collecting box 10 for centralized collection.
