Description

Technical Field

[0001] The utility model relates to the field of rice production and processing, in particular to a rice polishing and anti - breaking rice milling roll. Background Art

[0002] After the paddy is husked, it becomes brown rice. After most of the cortex and a part of the embryo are removed from the brown rice, it becomes rice. There is still a small amount of bran powder on the surface of the white rice grains, which affects the appearance quality, storability of the rice and the taste of the cooked rice. Therefore, it is necessary to remove this part of bran powder through the "polishing" process. Polishing is one of the key processes in the processing of clean rice. Since polishing can remove the bran powder on the surface of the rice grains, appropriate polishing can gelatinize the starch on the surface of the rice grains, presenting a certain luster, with good appearance effect and improved commercial value. At present, most of the rice polishing is carried out by using a rice milling roll with protrusions to stir the rice.

[0003] However, in order to ensure the cleaning effect of the bran powder on the rice grains, usually the distance between the protrusions of the rice milling roll and the outer filter cylinder is reduced, and it is easy to crush the rice grains when the rice grains are stirred and polished. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a rice polishing and anti - breaking rice milling roll, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical scheme: A rice polishing and anti - breaking rice milling roll, including a filter cylinder and a rice milling roll. At both ends of the inner side wall of the filter cylinder, rotating ear plates are annularly arrayed. Inside the rotating ear plates, there are ash - hitting plates. Between the ash - hitting plates and the rotating ear plates, there are elastic rotating shafts. On one side of the ash - hitting plates, there are support blocks installed on the inner side wall of the filter cylinder. On the outer side wall of the rice milling roll, installation chucks are annularly arrayed. Inside the installation chucks, there are brushes, and positioning bolts are installed between the brushes and the installation chucks.

[0006] As a further scheme of the utility model: Between two adjacent installation chucks, on the side surface of the rice milling roll, there are convex ribs, and inside the rice milling roll between the convex ribs and the installation chucks, there are cleaning spray holes.

[0007] As a further scheme of the utility model: At both ends of the rice milling roll, there are transmission shafts installed, and filter holes are opened inside the filter cylinder.

[0008] As a further scheme of the utility model: The ash - hitting plates are movably connected to the rotating ear plates through the elastic rotating shafts.

[0009] As a further scheme of the utility model: The support blocks are fixedly connected to the filter cylinder.

[0010] As a further solution of the utility model: the convex ribs are fixedly connected with the rice milling roller, and the cleaning spray holes are arranged through the rice milling roller.

[0011] As a further solution of the utility model: the brush is fixedly engaged with the mounting seat through the positioning bolt.

[0012] As a further solution of the utility model: the transmission shaft is fixedly connected with the rice milling roller, and the filter holes are arranged through the filter cylinder.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] When the rice grains continue to move and pass through the brush, they will be continuously cleaned, so that the rice bran is cleaned and intercepted by the mounting seat. When there is residual rice bran inside the brush, the rotation of the rice milling roller will drive the brush to impact the ash-beating plate, and then the rice bran remaining inside the brush will be scattered. It is not necessary to set the length of the convex ribs too long, reducing the occurrence of broken rice during polishing.

[0015] During rotation, the brush can also sweep down the rice bran blocking the filter holes on the filter cylinder, facilitating the discharge of the shaken-off rice bran to the outside and preventing the rice grains from adhering to the rice bran when the rotation stops.

Detailed Embodiment

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figures 1-4 shown, this embodiment provides a rice polishing and anti-breaking rice milling roller, which includes a filter cylinder 1 and a rice milling roller 2. Rotating ear plates 4 are annularly arranged at both ends of the inner side wall of the filter cylinder 1. A dusting plate 102 is arranged inside the rotating ear plate 4. An elastic rotating shaft 103 is installed between the dusting plate 102 and the rotating ear plate 4. The dusting plate 102 is movably connected to the rotating ear plate 4 through the elastic rotating shaft 103. A support block 104 is installed on one side of the dusting plate 102 on the inner side wall of the filter cylinder 1. The support block 104 is fixedly connected to the filter cylinder 1. The support block 104 is installed in the direction of the dusting plate 102 resetting towards the inner side wall of the filter cylinder 1, which can support the dusting plate 102 and prevent the dusting plate 102 from fitting to the inner side wall of the filter cylinder 1. Installation seats 203 are annularly arranged on the outer side wall of the rice milling roller 2. A brush 204 is arranged inside the installation seat 203. A positioning bolt 205 is installed between the brush 204 and the installation seat 203. The brush 204 is fixedly engaged with the installation seat 203 through the positioning bolt 205.

[0023] As Figures 2-3 shown, in this embodiment, a rib 201 is installed on the side surface of the rice milling roller 2 between two adjacent installation seats 203. The rib 201 is fixedly connected to the rice milling roller 2. A cleaning spray hole 202 is opened inside the rice milling roller 2 between the rib 201 and the installation seat 203. The cleaning spray hole 202 is used for spraying water and gas. The cleaning spray hole 202 is communicated with the rice milling roller 2. Transmission shafts 3 are installed at both ends of the rice milling roller 2. The transmission shafts 3 are fixedly connected to the rice milling roller 2. Filter holes 101 are opened inside the filter cylinder 1. The filter holes 101 penetrate through the filter cylinder 1.

[0024] The working principle of the present utility model is as follows: during use, the rice milling roller 2 is integrally installed inside the filter cylinder 1, and the rice is entirely put into the gap between the rice milling roller 2 and the filter cylinder 1. By driving the overall rotation of the rice milling roller 2, the rotation direction is set to be opposite to the reset direction of the ash scraping plate 102. First, after injecting a certain amount of water into the interior through the cleaning spray holes 202 by external clean water, the water can weaken the binding force between the endosperm and a small amount of rice bran remaining on the rice, which is beneficial to thoroughly removing the rice bran and improving the smoothness and polishing uniformity of the rice. During rotation, the ribs 201 provided on the outer side of the rice milling roller 2 are used to agitate the rice grains. When the rice grains are agitated and rotated, the rice bran above will be shaken off. When the rice grains continue to move and pass through the brush 204, they will be continuously cleaned, so that the rice bran is intercepted and cleaned by the mounting seat 203. When there is residual rice bran inside the brush 204, the rotation of the rice milling roller 2 will drive the brush 204 to impact the ash scraping plate 102, and the rice bran remaining inside the brush 204 will be scattered. At the same time, during rotation, the brush 204 can also sweep down the rice bran blocked in the filter holes 101 on the filter cylinder 1, which facilitates the discharge of the shaken-off rice bran to the outside and prevents the rice grains from continuing to adhere to the rice bran when the rotation stops.

[0025] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
