Description

Technical Field

[0001] The invention relates to the technical field of rice processing equipment, in particular to a multi-roller polishing equipment for rice polishing. Background Art

[0002] After brown rice is milled, a small amount of bran powder still remains on the surface of the rice grains, which affects the appearance quality, storage quality and taste of the rice. By adding an appropriate amount of water for "polishing", it is helpful to completely remove the rice bran on the surface of the rice grains, and it can also gelatinize the starch on the surface of the rice grains, improve the smoothness of the rice, and improve the appearance of the rice while facilitating its preservation.

[0003] When polishing rice, a wetting component needs to be set at the feed port to wet the rice in advance. When the rice is wetted, not only the surface becomes relatively soft, but also the binding force between rice bran and rice is weakened, making the friction between the polishing equipment and the rice surface more uniform and the surface of the polished rice smoother. At the same time, after the wetting treatment, the rice absorbs a certain amount of water, the internal structure is softened to a certain extent, and the toughness is increased, which can effectively reduce the broken rice rate.

[0004] However, the prior art has the following deficiencies when polishing and wetting rice: first, only the upper layer of rice opposite to the water outlet pipe can be wetted, while the bottom rice cannot be wetted, the rice is not wetted evenly, and the contact time between the rice and water is short, so the wetting is not thorough, the broken rice rate is still high, and the rice processing quality is low; second, when polishing rice, the existing rice polishing machine generally transports the rice directly through the lower hopper to the polishing roller for polishing, and the bottom of the lower hopper is prone to blockage, which affects the efficiency of feeding. Summary of the invention

[0005] The invention aims to provide a multi-roller polishing device for rice polishing, which can solve the above technical problems, and has the effects of uniform and thorough rice wetting, uniform polishing, low rice breaking rate, high processing quality and smooth material loading.

[0006] The above technical purpose of the present invention is achieved through the following technical solutions: a multi-roller polishing equipment for rice polishing, including a shell, a feed port is provided above the shell, a polishing assembly is provided inside, a feed hopper is provided above the feed port, a circular cavity is connected to the bottom of the feed hopper, the feed port is connected below the cavity, a rotating shaft is rotatably connected in the cavity, a plurality of partition plates are evenly fixed along the circumference of the rotating shaft, the partition plates and adjacent partition plates form a temporary storage wetting space, a row of water spray pipes are respectively fixed on both sides of the partition plates, the water spray pipes on both sides of the same temporary storage wetting space are parallel and staggered up and down, the rotating shaft, the partition plates and the water spray pipes are hollow inside and connected to each other, molecular pores are evenly provided on the water spray pipes, and a water supply assembly for introducing wetting water into the rotating shaft is also included.

[0007] By adopting the above technical scheme, by arranging a rotating shaft, a partition plate and a water spray pipe in the cavity, the rice can be dropped into the temporary storage and wetting space formed by the two partition plates and then rotated to discharge the rice, which can extend the contact time between the rice and the wetting water. The water spray pipes arranged in parallel and staggered up and down are inserted into different upper and lower positions of the rice in the temporary storage and wetting space, thereby achieving uniform humidity and deep wetting of the rice, and effectively avoiding the problem of broken rice caused by uneven wetting; at the same time, the rice can obtain a longer period of wetting treatment during the polishing process, making the polishing effect more ideal; in addition, the circular cavity, the rotating shaft and the partition plate design at the bottom of the feed hopper enable the rice to fall into the shell in batches, which greatly improves the smoothness of the discharge, reduces the risk of blockage, and ensures the continuity and efficiency of the entire polishing process.

[0008] The present invention is further configured as follows: a baffle plate is provided at the bottom of the feed hopper, when the feed hopper is opposite to a temporary storage and moistening space, the baffle plate and a partition plate close to one side of the baffle plate are located on the same straight line, and the bottom of the baffle plate is rotatably connected to the partition plate.

[0009] By adopting the above technical solution, the setting of the baffle plate enables the rice in the feed hopper to fall into a single storage moistening space more accurately each time, ensuring that the temporary storage time of each batch of rice in the storage moistening space is consistent, thereby ensuring the consistency of rice moisture, further improving the polishing efficiency of the equipment and the quality of rice.

[0010] The present invention is further configured as follows: the polishing assembly comprises polishing rollers, at least two polishing rollers are provided, and the polishing rollers are rotatably arranged in the housing.

[0011] By adopting the above technical solution, two polishing rollers are arranged in the shell, so as to improve the polishing efficiency of rice, so that the rice can be polished more fully and evenly when passing through the polishing rollers.

[0013] By adopting the above technical scheme, the polishing motor drives the driving wheel and the polishing roller to rotate, and the belt rotation drives the driven wheel and the other polishing roller to rotate. Through the design of the driving wheel and the driven wheel, the synchronous rotation between the polishing rollers is achieved, ensuring the stability and uniformity of the rice during the polishing process; two parallel polishing rollers are set to polish the rice, and the polishing efficiency is high; the driving wheel and the driven wheel are set in a protective cover to protect the driving wheel and the driven wheel, and it can also avoid accidental injury to the staff when the driving wheel and the driven wheel rotate at high speed, which is safer.

[0014] The present invention is further configured as follows: a material discharge channel is provided at one end of the housing away from the polishing motor.

[0015] By adopting the above technical solution, a feeding channel is provided to facilitate the feeding of polished rice.

[0016] The present invention is further configured to include a drive motor, which is used to drive the rotating shaft to rotate.

[0017] By adopting the above technical solution and arranging a driving motor to drive the rotating shaft to rotate, the rotating speed can be adjusted, thereby controlling the material feeding speed and saving manpower.

[0019] By adopting the above technical solution, the water pump pumps the moistening water in the water tank into the rotating shaft through the water inlet pipe, so that the moistening water fills the rotating shaft. After flowing through the rotating shaft and the partition plate, the moistening water is sprayed onto the surface of the rice through the molecular holes on the water spray pipe to form a uniform wet layer, which not only ensures the wetness of the rice during the polishing process, but also avoids the reduction of the polishing effect due to excessive moisture.

[0020] The present invention is further configured as follows: a plurality of rows of molecular pores are arranged, and the plurality of rows of molecular pores are evenly arranged along the circumference of the water spray pipe.

[0021] The beneficial effects of the present invention are:

[0022] 1. The present application can drop rice into a temporary storage and wetting space formed by two adjacent partitions by arranging a rotating shaft, a partition plate, and a water spray pipe. The rotating shaft rotates to realize the rice dropping to the feed port in batches. In the process of rotating with the rotating shaft, the rice will not only be temporarily stored in the temporary storage and wetting space for a period of time to ensure that the rice is fully humidified, but will also turn over in the temporary storage and wetting space as the rotating shaft rotates, further ensuring the wetting uniformity, so that the rice is evenly polished, reducing physical damage to the rice, and improving the polishing efficiency and rice quality; at the same time, the water spray pipes arranged in parallel and staggered up and down in the temporary storage and wetting space are inserted into different upper and lower positions of the rice in the temporary storage and wetting space, thereby realizing all-round humidification and polishing of the rice, effectively avoiding the problem of uneven wetting, and having the advantages of high and sufficient humidification efficiency.

[0023] 2. The present application forms a plurality of temporary storage and moistening spaces by setting a rotating shaft and a partition plate, and sets a rotating component to drive the partition plate and the rotating shaft to rotate, thereby driving the loading and unloading of rice in the temporary storage and moistening space.

DETAILED DESCRIPTION

[0030] The technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment, a rice polishing multi-roller polishing device, such as Figure 1 , Figure 2 , Figure 3 As shown, it includes a shell 1, a feed port 2 is provided on the top of the shell 1, a polishing component 3 is provided inside, a feed hopper 4 is provided above the feed port 2, a circular cavity 5 is connected to the bottom of the feed hopper 4, the bottom of the cavity 5 is connected to the feed port 2, and a rotating shaft 6 is rotatably connected inside, a plurality of partition plates 7 are evenly fixed along the circumference of the rotating shaft 6, the partition plates 7 and adjacent partition plates 7 form a temporary storage wetting space 8, a row of water spray pipes 9 are respectively fixed on both sides of the partition plates 7, the water spray pipes 9 on both sides of the same temporary storage wetting space 8 are parallel and staggered up and down, the rotating shaft 6 and the partition plates 7 are hollow inside and connected to each other, the water spray pipes 9 are hollow inside and are connected to the partition plates 7, and molecular pores 10 are evenly provided on the water spray pipes 9, and also include a water supply component 11 for introducing wetting water into the rotating shaft 6, including a water pump 112, a water storage tank 111, and a water inlet pipe 113, and a driving motor 14 for driving the rotating shaft 6 to rotate.

[0032] Its working principle is: first, the rice to be polished is loaded into the feed hopper 4, and the rice will enter the cavity 5 through the feed hopper 4. Since a partition plate 7 is provided in the cavity 5, the rice will be stored in the temporary storage and moistening space 8 formed by the partition plate 7 and the inner wall of the cavity 5. Then, the rotating shaft 6 rotates a certain angle, and the subsequent rice is dropped into the next temporary storage and moistening space 8. The rotating shaft 6 rotates multiple times to achieve continuous dropping. At this time, the rice will be temporarily stored in the temporary storage and moistening space 8 for a period of time. The parallel and vertically staggered water spray pipes 9 are inserted into different upper and lower positions of the rice for moistening. The humidification efficiency is high and the polishing is more uniform. When the temporary storage and moistening space 8 moves to the feed port 2, the rice is dropped into the shell 1 by its own gravity. At this time, the polishing component 3 starts to work. The rice is separated from the rice bran under the action of the polishing component 3, and the surface of the rice gradually becomes smooth.

[0033] Specifically, the water supply assembly 11 includes a water tank 111 and a water pump 112. The water pump 112 is used to pump the moist water in the water tank 111 into the interior of the rotating shaft 6 through a water inlet pipe 113. The water inlet pipe 113 is rotatably connected to the rotating shaft 6 through a bearing seal.

[0034] Secondly, when humidifying the rice, the water pump 112 is started to pump the wetting water in the water storage tank 111 into the rotating shaft 6 through the water inlet pipe 113, so that the wetting water fills the rotating shaft 6, flows through the rotating shaft 6 through the partition plate 7, and then is sprayed to the surface of the rice through the molecular holes 10 on the water spray pipe 9 to form a uniform wetting layer. When the rice falls from the feed hopper 4, it is wetted by the water spray pipe 9. At the same time, when the rice is stacked, the water spray pipe 9 is located inside the rice and is wetted. The rice will also turn over in the temporary storage wetting space 8 as the rotating shaft 6 rotates, further ensuring the wetting uniformity, thereby improving the polishing efficiency.

[0035] Specifically, a baffle plate 12 is provided at the bottom of the feed hopper 4. When the feed hopper 4 is opposite to the temporary storage and moistening space 8, the baffle plate 12 and the partition plate 7 close to one side of the baffle plate 12 are located on the same straight line, and the bottom of the baffle plate 12 is rotatably connected to the partition plate 7.

[0036] like Figure 3 As shown, by setting a baffle plate 12 at the bottom of the feed hopper 4, the rice in the feed hopper 4 can fall into a single storage moistening space more accurately each time, ensuring that each batch of rice has a consistent temporary storage time in the storage moistening space, thereby ensuring consistent rice moisture content, further improving polishing efficiency and rice quality.

[0037] Specifically, the polishing assembly 3 includes a polishing roller 31 . At least two polishing rollers 31 are provided. The polishing rollers 31 are rotatably disposed in the housing 1 .

[0038] Specifically, two polishing rollers 31 are provided, and the two polishing rollers 31 are arranged in parallel. A protective cover 32 is provided on the outside of the shell 1, and a polishing motor 33 is provided outside the protective cover 32. A driving wheel 34 is fixedly provided at one end of one polishing roller 31, and a driven wheel 35 is provided at one end of the other polishing roller 31. The driving wheel 34 and the driven wheel 35 are connected by a belt 36, and the polishing motor 33 is used to drive the driving wheel 34 to rotate.

[0039] like Figure 2 As shown, the rice is polished by arranging two parallel polishing rollers 31, and the polishing efficiency is high; the polishing motor 33 drives the driving wheel 34 and the polishing roller 31 to rotate, so that the belt 36 rotates to drive the driven wheel 35 and the other polishing roller 31 to rotate. Through the design of the driving wheel 34 and the driven wheel 35, the synchronous rotation between the polishing rollers 31 is achieved, and the stability and uniformity of the rice during the polishing process are ensured; the driving wheel 34 and the driven wheel 35 are rotatably arranged in the protective cover 32, which plays a role in protecting the driving wheel 34 and the driven wheel 35, and can also avoid accidental injury to the staff when the driving wheel 34 and the driven wheel 35 rotate at high speed, which is safer.

[0040] Specifically, a discharge channel 13 is provided at one end of the housing 1 away from the polishing motor 33 to facilitate the discharge of polished rice.

[0041] Specifically, the molecular holes 10 are arranged in multiple rows, and the multiple rows of molecular holes 10 are evenly arranged along the circumference of the water spray pipe 9, so that the multiple rows of molecular holes 10 are evenly arranged around the circumference of the water spray pipe 9, and the rice around the water spray pipe 9 can be wetted, further increasing the wetted area of ​​the rice and strengthening the wetting effect of the water spray pipe 9.
