Description

Technical Field

[0001] This invention relates to the field of rice processing technology, and in particular to a rice processing equipment and a rice processing technology. Background Technology

[0002] Rice, also known as paddy rice, is a food made from paddy rice through cleaning, hulling, milling, and finishing processes. Rice contains nearly 64% of the nutrients found in paddy rice and over 90% of the nutrients needed by the human body. It is a staple food for people in most parts of China. When rice matures, it is harvested using combine harvesters, then threshed to obtain paddy rice, which is then processed to remove the husks. Paddy rice is nutritious and reasonably priced, and after processing, it appears on people's tables, consistently being a popular staple food. With the improvement of people's living standards, their demands for rice quality are increasing.

[0003] In the rice processing process, rice is typically screened to classify its quality. However, existing rice processing equipment requires numerous screening steps, making the process more complex and requiring more equipment. Therefore, to achieve both precise screening and a simplified, faster process, this paper proposes a rice processing device and technology. Summary of the Invention

However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the present invention, and these aspects of the invention can be implemented even without these specific details.

[0029] like Figure 1As shown, a rice processing equipment and process includes a chassis 1, which is mounted on a support base 6. The support base 6 supports and fixes the chassis 1. A self-locking caster wheel 8 is provided at the bottom of the support base 6, allowing the support base 6 to be moved or locked in a fixed position. A feed hopper 11 is located on the top right side of the chassis 1, through which rice enters the interior of the chassis 1. A first guide plate 12 is located below the feed inlet of the feed hopper 11, positioned on the upper right side wall inside the chassis 1. Rice entering from the feed hopper 11 falls onto the first guide plate 12. Below the first guide plate 12 is a... The blowing assembly 2 disperses the rice falling from the first guide plate 12. A second guide plate 13 is located below the blowing assembly 2, onto which any pebbles that are not blown away fall. A rice milling box 3 is located on the upper left side wall inside the machine housing 1, used to remove the rice husk. A sieve 4 is located below the rice milling box 3, onto which the husk-removed rice falls. A third discharge port 14 is located at the bottom of the machine housing 1, below the sieve 4. The bottom of the machine housing 1 has a conical structure, and the third discharge port 14 is located at the bottom of this conical structure. The rice falling from the sieve 4 flows out through the third discharge port 14. The blowing assembly 2 of this invention disperses the rice falling from the first guide plate 12, causing the rice to fall into the rice milling box 3, while pebbles and other heavy objects fall onto the second guide plate 13, thus removing the pebbles.

[0030] In an embodiment of the present invention, a dust removal device 7 is provided on the left and lower right sides of the top of the casing 1. The dust removal device 7 is used to treat dust, rice dust, and other substances. The dust removal device 7 is provided with a dust collection pipe 71, which extends into the interior of the casing 1. Dust, rice dust, and other substances enter the dust removal device 7 through the dust collection pipe 71 for treatment. One end of the first guide plate 12 is connected to the upper right side wall inside the casing 1. A vibrator 15 is provided at the bottom of the first guide plate 12. The vibrator 15 drives the first guide plate 12 to vibrate, causing the rice to separate and not clump. The first guide plate 12 is inclined to the left side of the casing 1, so that the rice flows down to the left side of the casing 1. The left end of the second guide plate 13 is connected to the right end of the rice milling box 3, and the right end of the second guide plate 13 is connected to the casing 1. The right end of the second guide plate 13 is provided with a first discharge port 131. The second guide plate 13 is inclined to the right side of the casing 1. Rice falling from the first guide plate 12 is blown by the blower assembly 2 below the first guide plate 12 to the top of the rice milling box 3. The stones that are not blown away fall onto the second guide plate 13 and flow out from the first discharge port 131.

[0031] like Figure 2As shown, the blowing assembly 2 includes a fan 21, an air supply pipe 22, and an air outlet box 24. The fan 21 is mounted on a fan support 25, which supports and fixes the fan 21. One end of the air supply pipe 22 is connected to the fan 21, and the other end of the air supply pipe 22 is connected to two guide pipes 23. The guide pipes 23 are connected to the air outlet box 24, and the air outlet box 24 is provided with an air outlet 26. The air generated by the fan 21 enters the two guide pipes 23 through the air supply pipe 22, enters the air outlet box 24 from the two guide pipes 23, and then exits through the air outlet 26 of the air outlet box 24, thereby blowing the rice above the rice milling box 3, and then the rice falls into the rice milling box 3.

[0032] In an embodiment of the present invention, the air outlet box 24 includes an upper top plate 241, a lower bottom plate 242, a rear side plate 243, and an arc-shaped air guide plate 244. The rear side plate 243 is connected to the upper top plate 241 and the lower bottom plate 242 respectively, and is fixed to the upper top plate 241 and the lower bottom plate 242 by welding. A side plate 245 is connected between the upper top plate 241 and the lower bottom plate 242, and is fixed to the upper top plate 241 and the lower bottom plate 242 by welding. The arc-shaped air guide plate 244 is connected to the upper top plate 241, and is fixed to the upper top plate 241 by welding. The arc-shaped air guide plate 244 is connected to an upper air outlet plate 246, and the lower bottom plate 242 is connected to a lower air outlet plate 247. The upper air outlet plate 246 and the lower air outlet plate 247 form an air outlet 26. The bottom plate 242 is provided with two holes and connected to two air guide pipes 23. After the two air guide pipes 23 enter the air outlet box 24, they are blown out from the air outlet 26 formed by the upper air outlet plate 246 and the lower air outlet plate 247 through the arc-shaped air guide plate 244.

[0033] like Figure 1 and Figure 3As shown, the left end of the rice milling box 3 is connected to the upper left side wall inside the machine casing 1. A rice milling motor 31 is installed on the outer left side wall of the machine casing 1. The rice milling motor 31 is connected to the machine casing 1. The output end of the rice milling motor 31 is connected to a first rice milling screen roller 32. The rice milling motor 31 drives the first rice milling screen roller 32 to rotate. One end of the first rice milling screen roller 32 is connected to a drive gear 33. The drive gear 33 follows the rotation of the first rice milling screen roller 32. The drive gear 33 is meshed with a drive gear... A driven gear 34 rotates following a driving gear 33. The driven gear 34 is connected to one end of a second rice milling screen roller 35, which rotates with the driven gear 34. The second rice milling screen roller 35 and the first rice milling screen roller 32 are respectively disposed inside the rice milling box 3, with a gap 36 between them. Rice falls into the gap 36 and is milled by the second rice milling screen roller 35 and the first rice milling screen roller 32 to remove the rice husk. When the rice milling motor 31 is started, it drives the first rice milling screen roller 32 to rotate. The driving gear 33 rotates with the first rice milling screen roller 32, and the driven gear 34 rotates with the driving gear 33, thereby causing the second rice milling screen roller 35 to rotate with the driven gear 34. This further causes the rice falling into the rice milling box 3 to have its husk removed by the first rice milling screen roller 32 and the second rice milling screen roller 35.

[0034] like Figure 1 and Figure 4 As shown, mounting holes 41 are respectively provided on the lower left and lower right sides of the casing 1. A connecting block 42 is provided inside the mounting hole 41. A screen motor 43 is connected to the outer end of the connecting block 42. Vibration springs 44 are respectively connected to the upper and lower ends of the connecting block 42. The vibration springs 44 can support the connecting block 42 and also play a buffering role during operation, reducing the impact and wear on the equipment. The vibration springs 44 are located inside the mounting hole 41, and one end of the vibration springs 44 is connected to the casing 1. The screen 4 is connected to the inner end of the connecting block 42. The screen 4 is inclined to the right side of the casing 1. A second discharge port 45 is provided at the right end of the screen 4. Rice from the rice milling box 3 falls onto the screen 4. The screen motor 43 drives the screen 4 to screen. The dust removal device 7 on the lower right side of the casing 1 treats the rice surface. The rice on the screen 4 flows out from the second discharge port 45, and the rice under the screen 4 flows out from the third discharge port 14.

[0035] A rice processing technology includes the following steps:

[0036] (1) The blowing assembly removes stones from the rice, causing the rice to fall into the rice milling box. Dust and other substances enter the dust removal device, and the stones fall onto the second guide plate and flow out. The blower of the blowing assembly sends air to the air outlet box through the air supply pipe. The air comes out through the air outlet of the air outlet box and blows away the rice falling from the first guide plate. The rice falls into the rice milling box, and the dust and other substances are processed by the dust removal device. The stones and other heavy objects fall onto the second guide plate and go out from the first discharge port, thus achieving the removal of stones.

[0037] (2) The rice husk is crushed off by the first and second rice milling rollers in the rice milling box, and the rice falls onto the screen below the rice milling box; the rice milling box drives the first and second rice milling rollers through the rice milling motor to crush off the rice husk and the rice falls onto the screen below the rice milling box.

[0038] (3) The rice is screened by a screen. The screen motor drives the screen to vibrate. The rice skin is treated by a dust removal device. The rice on the screen flows out from the second discharge port and the rice under the screen flows out from the third discharge port. The screen motor drives the screen to screen. The dust removal device on the lower right side of the machine box treats the rice skin. The rice on the screen flows out from the second discharge port and the rice under the screen flows out from the third discharge port, thus achieving the screening of high-quality rice.
