Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a rice bran screening device for selenium-enriched rice production. Background Art

[0002] Rice, as one of the most common crops, has an increasing production volume. In the process of processing rice into polished rice, the outer shell and the pericarp, seed coat, endosperm, aleurone layer and embryo, which account for about 10% of the total weight, must be removed. Traditional rice bran, that is, the current national standard rice bran, is mainly made from pericarp, seed coat, endosperm, aleurone layer and embryo. Therefore, a small amount of rice husk and a certain amount of dust and microorganisms will be mixed in during the processing. Therefore, rice bran can only be used as feed and is the main by-product of rice processing. If the bran is not screened, it will greatly affect the consumption. Therefore, a bran screening device is required to remove the rice bran from the rice to meet people's taste requirements.

[0003] The existing rice bran screening equipment has low screening efficiency and poor screening effect, is not suitable for industrial application, and greatly reduces the user experience.

[0023] See also Figures 1 to 3 A rice bran screening device for selenium-rich rice production includes a feeding box 10 for inputting rice and rice bran, a receiving box 20 installed on a first side of the feeding box 10 and connected to the feeding box 10, a blowing component 30 installed on a second side of the feeding box 10 opposite to the first side and used to blow the rice bran dropped in the feeding box 10 into the receiving box 20, a filtering box 40 installed at the bottom of the feeding box 10 and used to receive the rice and rice bran output from the discharge port of the feeding box 10 and filter them to output rice, a first scattering component 50 installed in the filtering box 40 and used to scatter the rice and rice bran, and a sliding box 60 installed at the bottom of the filtering box 40 and used to receive the rice output from the filtering box 40.

[0024] Specifically, in this embodiment, during operation, rice and rice bran are input into the feeding box 10 from the feeding port above the feeding box 10. During the falling process, the lighter rice bran is blown into the receiving box 20 driven by the blowing component 30 for initial screening. After entering the filter box 40, the smaller rice is output from the bottom of the filter box 40 to the sliding box 60, and is transported to the next process driven by the sliding box 60, while the larger rice bran stays in the filter box 40 waiting to be removed for secondary screening. During the filtering process, the first scattering component 50 fully scatters and stirs the rice and rice bran, thereby effectively improving the filtering effect.

[0025] The utility model relates to a rice bran screening device for selenium-rich rice production. The arrangement of a blowing component 30, a filter box 40 and a first breaking component 50 can effectively perform secondary screening on rice and rice bran, thereby achieving good filtering effect, being suitable for industrial applications, and greatly improving the user experience.

[0026] In a specific embodiment, a first filter net 401 is disposed at the bottom of the filter box 40. In this embodiment, the first filter net 401 is disposed so that rice can be effectively filtered out of the filter box 40.

[0027] In a specific embodiment, the blowing assembly 30 includes a mounting plate 301 mounted on the second side of the material box 10, and a plurality of blowing fans (not shown in the figure) mounted on the mounting plate 301 for blowing the rice bran falling in the material box 10 into the material receiving box 20. In this embodiment, by providing a plurality of blowing fans, the rice bran can be quickly blown into the material receiving box 20, thereby improving the primary screening efficiency.

[0028] In a specific embodiment, the first breaking up assembly 50 includes a first rotating shaft 501 installed in the filter box 40, a plurality of connecting rods 502 installed side by side on the outer periphery of the first rotating shaft 501, a first stirring rod 503 connected to the plurality of connecting rods 502, and a first driving unit connected to the first rotating shaft 501 for driving the first rotating shaft 501 to rotate. Specifically, in this embodiment, the first driving unit drives the first rotating shaft 501 to rotate, and then drives the stirring shaft to rotate through the connecting rod 502, so that when the filter box 40 is filtering, the rice bran and the rice are effectively broken up, thereby improving the filtering effect of the filter box 40. Further, the first driving unit includes a first driving motor 504 and a reducer 505 connected to the driving motor and the rotating shaft. In this embodiment, the first driving motor 504 drives the rotating shaft to rotate through the reducer 505.

[0029] In a specific embodiment, a second scattering assembly 70 for scattering rice and rice bran is provided in the material box 10. In this embodiment, the second scattering assembly 70 can effectively scatter the rice and rice bran falling into the material box 10, so that the blowing assembly 30 can effectively blow the rice bran into the receiving box 20. Furthermore, the second scattering assembly 70 includes a second rotating shaft installed in the material box 10, a second driving unit connected to the second rotating shaft and used to drive the second rotating shaft to rotate, and a second stirring rod 701 installed on the outer periphery of the second rotating shaft. Specifically, during operation, the second driving unit drives the second rotating shaft to rotate, thereby driving the second stirring rod 701 to rotate, so as to effectively scatter the rice and rice bran. The second driving unit includes a second driving motor 702 connected to the second rotating shaft. The material box 10 is divided from top to bottom into a material box for receiving the rice and rice bran transported from the outside, and a transition chamber connected to the material box and the filter box 40; the material box 20 and the blowing assembly 30 are respectively installed on two opposite sides of the transition chamber; the second scattering assembly 70 is installed in the material box. Specifically, in this embodiment, the arrangement of the material box and the transition chamber effectively prevents the second scattering assembly 70 from affecting the blowing assembly 30 and the material box 20 when scattering the rice and rice bran.

[0030] In a specific embodiment, the side of the filter box 40 is provided with a communication port 402. In this embodiment, the communication port 402 is used to connect an external exhaust pipe, so that when not in use, the rice bran in the filter box 40 can be conveniently removed through the exhaust pipe. It should be noted that when the filter box 40 is working, the communication port 402 can be closed by a baffle, etc., so as to prevent the rice or rice bran from escaping from the communication port 402 when the first scattering assembly 50 is working.

[0031] The utility model relates to a rice bran screening device for selenium-rich rice production. The arrangement of a blowing component 30, a filter box 40 and a first breaking component 50 can effectively perform secondary screening on rice and rice bran, thereby achieving good filtering effect, being suitable for industrial applications, and greatly improving the user experience.

[0032] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
