Description
Technical Field
[0001] The utility model relates to the field of rice processing, in particular to a small automatic rice polishing machine. Background Art
[0002] As an indispensable food in people's daily life, the importance of rice is self-evident. Brown rice has higher nutritional value than polished rice, but the taste of rice made from brown rice is poor. In order to improve the taste of rice while ensuring the quality of brown rice as much as possible, it is necessary to perform secondary processing on brown rice. The secondary processing of brown rice is generally processed by a rice polishing machine. The existing rice polishing machines are divided into medium and large rice polishing machines and small rice polishing machines. Among them, medium and large rice polishing machines have complex structures, occupy large space, and have high production costs; small rice polishing machines are small in size, but the current small rice polishing machines generally adopt an intermittent processing method, that is, a fixed amount of rice is added at a time for rice polishing, and the polished rice is manually taken out after the polishing is completed, and then the next rice polishing is performed. Due to the intermittent processing method, the current small rice polishing machine can only add a fixed amount of rice at a time, and cannot perform continuous rice polishing operations. In addition, the rice polishing machine processing process requires manual cooperation to take out the polished rice, so there are problems of inconvenience in operation and poor efficiency of rice polishing operations. Utility Model Content
[0003] The utility model aims to overcome the problem that the small-sized rice polishing machine in the prior art adopts an intermittent processing mode to polish rice, which is inconvenient to operate and affects the efficiency of the rice polishing operation, and provides a small-sized automatic rice polishing machine which is easy to operate, can realize continuous rice polishing operation, and improves the efficiency of the rice polishing operation.
[0004] The technical solution of the utility model is:
[0005] A small automatic rice polishing machine, comprising:
[0006] Brown rice hopper;
[0007] The bran removal net cylinder has an inner cavity forming a polishing chamber, a brown rice inlet and a polished rice outlet are arranged on the bran removal net cylinder, and a brown rice hopper is connected to the brown rice inlet;
[0008] The rice polishing knife is located on the bran removal net cylinder and extends along the axial direction of the bran removal net cylinder. The rice polishing knife is provided with a forward feeding part and a reverse feeding part formed by spiral extension, wherein the forward feeding part is close to the brown rice inlet, the reverse feeding part is close to the polished rice outlet, and the spiral directions of the forward feeding part and the reverse feeding part are opposite;
[0009] The driving motor drives the rice polishing knife to rotate. The specific operation of the small automatic rice polishing machine of this scheme is as follows:
[0010] The driving motor drives the rice polishing knife to rotate; brown rice is added into the brown rice hopper, and the brown rice in the brown rice hopper is input into the polishing chamber of the bran removing net cylinder through the brown rice inlet; the brown rice in the polishing chamber moves along the axial direction of the bran removing net cylinder toward the polished rice outlet under the propulsion of the rotating forward feed part, and in this process, the rice grains are rubbed against each other to obtain polished rice, and the processed polished rice is output from the polished rice outlet, and the bran generated during the processing is discharged through the mesh holes of the bran removing net cylinder; in this way, continuous rice polishing operation can be realized by adding brown rice into the brown rice hopper, the operation is convenient, and the efficiency of rice polishing operation can be improved.
[0011] Furthermore, in order to improve the polished rice processing effect within a short distance, the present invention provides a reverse feed portion on the polished rice knife near the polished rice outlet, and the spiral direction of the reverse feed portion is opposite to that of the forward feed portion. In this way, during the rotation of the polished rice knife, the reverse feed portion will provide the brown rice in the polishing chamber with a propulsion force opposite to that of the forward feed portion (propulsion force from the polished rice outlet to the brown rice inlet), thereby enhancing the mutual friction effect of the rice grains in the polishing chamber and extending the mutual friction time of the rice grains in the polishing chamber, which can not only improve the polished rice processing effect, but also help shorten the length of the bran removal net cylinder, reduce the volume of the rice polishing machine, and achieve the purpose of improving the polished rice processing effect within a short distance.
[0012] Preferably, the bran removing net cylinder is inclinedly distributed, and the bran removing net cylinder extends obliquely upward from the brown rice inlet to the polished rice outlet. During the rotation of the polished rice knife, the brown rice is pushed along the axial direction of the bran removing net cylinder toward the polished rice outlet by the feeding part. Since the bran removing net cylinder extends obliquely upward from the brown rice inlet to the polished rice outlet, the mutual friction effect of the rice grains in the polishing chamber can be enhanced, and the time for the rice grains to rub against each other in the polishing chamber can be prolonged, which can not only improve the polished rice processing effect, but also help to shorten the length of the bran removing net cylinder, reduce the volume of the rice polishing machine, and achieve the purpose of improving the polished rice processing effect within a short distance.
[0013] Preferably, the inclination angle of the bran removal net cylinder is 8-25 degrees. The inclination angle of the bran removal net cylinder cannot be too large or too small. If the inclination angle of the bran removal net cylinder is too large, it will not only affect the efficiency of the polished rice processing, but also cause excessive friction of the rice grains during the polishing process, which will reduce the nutritional value of the polished rice; if the inclination angle of the bran removal net cylinder is too small, it will not enhance the mutual friction of the rice grains in the polishing chamber. Therefore, this scheme sets the inclination angle of the bran removal net cylinder to 8-25 degrees. In this way, on the one hand, it can enhance the effect and duration of the mutual friction of the rice grains in the polishing chamber, which can not only improve the polishing effect, but also help to shorten the length of the bran removal net cylinder, reduce the volume of the rice polishing machine, and achieve the purpose of improving the polishing effect of rice within a short distance; on the other hand, it can avoid the problem of excessive friction of rice grains, which reduces the nutritional value of polished rice.
[0014] Preferably, a bran inner cylinder is further included, wherein the bran removing net cylinder is located inside the bran inner cylinder, and a bran outlet is provided at the bottom of the bran inner cylinder. Thus, during the polished rice processing, the bran discharged through the mesh holes of the bran removing net cylinder will be collected by the bran inner cylinder and discharged through the bran outlet.
[0015] As preferably, also comprise bran container, bran container is positioned at bran outlet below, to collect bran discharged from bran outlet.Like this, in the polished rice processing, the bran discharged through bran outlet will be collected in bran container, is convenient for user to handle the bran produced in the polished rice processing.
[0016] Preferably, the rice container further comprises a rice container and a rice output channel, the polished rice outlet is connected to the rice output channel, a feeding port is provided at the bottom of the rice output channel, and the rice container is located below the rice container. In this way, during the polished rice processing, the polished rice outputted from the polished rice outlet will be discharged through the rice output channel and the feeding port and collected in the rice container, so that the user can process the processed polished rice.
[0017] As preferred, the driving motor is connected to the root of the polished rice knife, the feed portion is located at the root of the polished rice knife, and the bran removal net cylinder is opened at one end away from the root of the polished rice knife, and the opening forms a polished rice outlet. Such a layout is convenient for the installation and production of the small automatic rice polishing machine.
[0018] As preferably, the bran removal net cylinder can be detachably installed on the small automatic rice polishing machine. After the small automatic rice polishing machine uses for a period of time, the bran removal net cylinder can be disassembled from the rice polishing machine, so that the bran removal net cylinder is cleaned, to improve the use effect and prolong the service life.
[0019] Preferably, a valve plate and a driving member are provided at the bottom of the brown rice hopper, and the driving member drives the valve plate to open or close the bottom of the brown rice hopper. In this way, the valve plate can be driven by the driving member to control the opening or closing of the bottom of the brown rice hopper, which is convenient for actual polished rice processing operation.
[0020] Preferably, the rice polishing machine further comprises a control unit, the control unit communicates with the driving motor, and the control unit has a control unit for the user to control the speed of the driving motor.

The bran removal net cylinder 3 is provided with a brown rice inlet 3.1 and a polished rice outlet 3.2. The brown rice inlet 3.1 and the polished rice outlet 3.2 are sequentially distributed along the axial direction of the bran removal net cylinder 3. The brown rice hopper 2 is connected to the brown rice inlet 3.1.
[0039] The rice polishing knife 4 is located on the bran removal net cylinder 3 and extends along the axial direction of the bran removal net cylinder 3. The rice polishing knife 4 is provided with a forward feeding part 4.1 and a reverse feeding part 4.2 formed by spiral extension, wherein the forward feeding part 4.1 is close to the brown rice inlet 3.1, and the reverse feeding part 4.2 is close to the polished rice outlet 3.2. The spiral directions of the forward feeding part 4.1 and the reverse feeding part 4.2 are opposite.
[0040] The driving motor 5 is installed on the frame, and the conveying shaft of the driving motor 5 is connected with the rice polishing knife 4 to drive the rice polishing knife 4 to rotate.
[0041] The specific operation of the small automatic rice polishing machine of the present embodiment is as follows:

[0043] Brown rice is added into the brown rice hopper 2, and the brown rice in the brown rice hopper 2 is input into the polishing chamber of the bran removal net cylinder 3 through the brown rice inlet 3.1.
[0044] The brown rice in the polishing chamber moves along the axial direction of the bran removal net cylinder 3 toward the polished rice outlet 3.2 under the propulsion of the rotating forward feeding part 4.1. In this process, the rice grains are rubbed against each other to obtain polished rice. The processed polished rice is output from the polished rice outlet 3.2, and the bran generated during the processing is discharged through the mesh of the bran removal net cylinder 3. In this way, continuous polished rice processing can be achieved by adding brown rice to the brown rice hopper 2, which is easy to operate and can improve the efficiency of the polished rice processing operation. Furthermore, in order to improve the polished rice processing effect within a short distance, the present embodiment is provided with a reverse feed portion 4.2 on the polished rice knife 4 near the polished rice outlet 3.2, and the spiral direction of the reverse feed portion 4.2 is opposite to that of the forward feed portion 4.1. Thus, during the rotation of the polished rice knife 4, the reverse feed portion 4.2 will provide the brown rice in the polishing chamber with a propulsion force opposite to that of the forward feed portion 4.1 (propulsion force from the polished rice outlet 3.2 to the brown rice inlet 3.1), thereby enhancing the mutual friction effect of the rice grains in the polishing chamber and extending the mutual friction time of the rice grains in the polishing chamber, which can not only improve the polished rice processing effect, but also help to shorten the length of the bran removal net cylinder 3, reduce the volume of the rice polishing machine, and achieve the purpose of improving the polished rice processing effect within a short distance.
[0045] Specific embodiment 2, as Figure 1 , Figure 2 , Figure 3 As shown, a small automatic rice polishing machine includes a frame, a brown rice hopper 2, a bran removal net cylinder 3, a rice polishing knife 4 and a driving motor 5.
[0046] The bran removal net cylinder 3 is installed on the frame. The inner cavity of the bran removal net cylinder 3 forms a polishing chamber. The bran removal net cylinder 3 is provided with a brown rice inlet 3.1 and a polished rice outlet 3.2. The brown rice inlet 3.1 and the polished rice outlet 3.2 are sequentially distributed along the axial direction of the bran removal net cylinder 3. In this embodiment, the brown rice inlet 3.1 is located at or near one end of the bran removal net cylinder 3, and one end of the bran removal net cylinder 3 where the brown rice inlet 3.1 is located is closed. The polished rice outlet 3.2 is located at or near the other end of the bran removal net cylinder 3.
[0047] The brown rice hopper 2 is fixed on the frame. The brown rice hopper 2 is communicated with the brown rice inlet 3.1.
[0048] The rice polishing knife 4 is located on the bran removal net cylinder 3 and extends along the axial direction of the bran removal net cylinder 3. The rice polishing knife 4 is provided with a forward feeding part 4.1 and a reverse feeding part 4.2 formed by spiral extension, wherein the forward feeding part 4.1 is close to the brown rice inlet 3.1, and the reverse feeding part 4.2 is close to the polished rice outlet 3.2. The spiral directions of the forward feeding part 4.1 and the reverse feeding part 4.2 are opposite.
[0049] The driving motor 5 is installed on the frame, and the conveying shaft of the driving motor 5 is connected with the rice polishing knife 4 to drive the rice polishing knife 4 to rotate.
[0050] The specific operation of the small automatic rice polishing machine of the present embodiment is as follows:
[0051] The driving motor 5 drives the rice polishing knife 4 to rotate. Brown rice is added to the brown rice hopper 2, and the brown rice in the brown rice hopper 2 is input into the polishing chamber of the bran removal net cylinder 3 through the brown rice inlet 3.1. The brown rice in the polishing chamber moves along the axial direction of the bran removal net cylinder 3 toward the polished rice outlet 3.2 under the propulsion of the rotating forward feed part 4.1. In this process, the rice grains are rubbed against each other to obtain polished rice. The processed polished rice is output from the polished rice outlet 3.2, and the bran generated during the processing is discharged through the mesh of the bran removal net cylinder 3. In this way, continuous polished rice processing can be achieved by adding brown rice to the brown rice hopper 2, which is easy to operate and can improve the efficiency of the polished rice processing operation. Furthermore, in order to improve the polished rice processing effect within a short distance, the present embodiment is provided with a reverse feed portion 4.2 on the polished rice knife 4 near the polished rice outlet 3.2, and the spiral direction of the reverse feed portion 4.2 is opposite to that of the forward feed portion 4.1. Thus, during the rotation of the polished rice knife 4, the reverse feed portion 4.2 will provide the brown rice in the polishing chamber with a propulsion force opposite to that of the forward feed portion 4.1 (propulsion force from the polished rice outlet 3.2 to the brown rice inlet 3.1), thereby enhancing the mutual friction effect of the rice grains in the polishing chamber and extending the mutual friction time of the rice grains in the polishing chamber, which can not only improve the polished rice processing effect, but also help to shorten the length of the bran removal net cylinder 3, reduce the volume of the rice polishing machine, and achieve the purpose of improving the polished rice processing effect within a short distance.
[0052] Specifically, the small automatic rice polishing machine also includes a control unit. The control unit communicates with the drive motor 5. In this embodiment, the control unit communicates with the drive motor 5 through wireless communication (such as Bluetooth wireless communication); or the control unit communicates with the drive motor 5 through wired communication, that is, the control unit and the drive motor 5 are connected through a signal line. The control unit has a control unit 7 for the user to operate to control the speed of the drive motor 5. In this way, the user can set the speed of the drive motor 5 through the control unit 7 to achieve different rice polishing levels. In this way, the user can choose different rice polishing levels according to their own needs, which is conducive to improving the user experience.
[0053] In this embodiment, the small automatic rice polishing machine further comprises a housing 1 , which is mounted on a frame. A control unit 7 is arranged on an outer side of the housing 1 .
[0054] In one implementation of this embodiment, Figure 1 As shown, the control unit 7 is a control knob, which has 3-5 polished rice processing gears, each of which corresponds to a speed of the driving motor 5. The user controls the speed of the driving motor 5 by rotating the control knob to different polished rice processing gears to select different polished rice processing levels.
[0055] In another implementation of this embodiment, the control unit 7 is a plurality of rice polishing gear buttons (not shown in the figure), each of which corresponds to a driving motor speed. The user controls the speed of the driving motor by pressing different rice polishing gear buttons to select different rice polishing levels.
[0056] In a third implementation of the present embodiment, the control unit 7 is a liquid crystal panel (not shown in the figure), and the liquid crystal panel has a plurality of rice polishing gear buttons, each of which corresponds to a driving motor speed. The user controls the speed of the driving motor by pressing different rice polishing gear buttons to select different rice polishing levels.
[0057] Further, such as Figure 1 As shown, the driving motor 5 is connected to the root of the rice polishing knife 4. The forward feeding part 4.1 is located at the root of the rice polishing knife 4. The reverse feeding part 4.2 is located at the front end of the rice polishing knife 4. Such a layout is convenient for the installation and production of a small automatic rice polishing machine.
[0058] In this embodiment, the thread pitch of the forward feed part 4.1 is smaller than the thread pitch of the reverse feed part 4.2. During the rice polishing process, the propulsion force of the forward feed part 4.1 on the rice grains is greater than the propulsion force of the reverse feed part 4.2 on the rice grains.
[0059] Further, such as Figure 1 As shown, the bran removal net cylinder 3 has an opening at one end away from the root of the rice polishing knife 4, and the opening forms a polished rice outlet 3.2. This facilitates the manufacture of the bran removal net cylinder 3 and is also conducive to the transportation of polished rice through the polished rice outlet 3.2. Of course, it should be noted that the polished rice outlet 3.2 can also be set at the lower part of the side wall of the bran removal net cylinder 3.
[0060] Further, such as Figure 1 , Figure 2 As shown, the small automatic rice polishing machine also includes a bran inner cylinder 6. The bran removing net cylinder 3 is located in the bran inner cylinder 6, and a bran outlet 6.1 is provided at the bottom of the bran inner cylinder 6. In this way, during the polished rice processing, the bran discharged through the mesh of the bran removing net cylinder 3 will be collected by the bran inner cylinder 6 and discharged through the bran outlet 6.1.
[0061] The small automatic rice polishing machine further comprises a bran container 10. The bran container 10 is located below the bran outlet 6.1 to collect the bran discharged from the bran outlet 6.1. The upper end of the bran container 10 is open. Thus, during the rice polishing process, the bran discharged through the bran outlet 6.1 will be collected in the bran container 10, which is convenient for the user to handle the bran generated during the rice polishing process.
[0062] In this embodiment, the bran container 10 is a bran storage barrel, and the bottom of the small automatic rice polishing machine is provided with a receiving cavity 11 with one side opening. The bran outlet 6.1 extends to the top of the receiving cavity 11. The bran container 10 is placed on the bottom surface of the receiving cavity 11, and the bran container 10 is placed in the receiving cavity 11 or taken out of the receiving cavity 11 through the one side opening of the receiving cavity 11.
[0063] Further, such as Figure 1 , Figure 2 As shown, the small automatic rice polishing machine also includes a rice container 9 and a rice output channel 8. The polished rice outlet 3.2 is communicated with the rice output channel 8. A feeding port 8.1 is provided at the bottom of the rice output channel 8. The rice container 9 is located below the rice container 9. The upper end of the rice container 9 is open. In this way, during the polished rice processing, the polished rice output by the polished rice outlet 3.2 will pass through the rice output channel 8 and the feeding port 8.1, be discharged and collected in the rice container 9, so that the user can handle the processed polished rice.
[0064] In this embodiment, the rice container 9 is a rice storage barrel, and the feeding port 8.1 extends to the top of the accommodating cavity 11. The rice container 9 is placed on the bottom surface of the accommodating cavity 11, and the rice container 9 is placed into the accommodating cavity 11 or taken out of the accommodating cavity 11 through an opening on one side of the accommodating cavity 11. In this embodiment, the bran container 10 and the rice container 9 are arranged together in the accommodating cavity 11, so that it is convenient for users to handle the processed polished rice and bran, which is conducive to improving user experience.
[0065] Furthermore, a valve plate and a driving member are provided at the bottom of the brown rice hopper. The driving member drives the valve plate to open or close the bottom of the brown rice hopper. In this embodiment, the driving member is a rotary motor, and the driving member drives the valve plate to rotate to open or close the bottom of the brown rice hopper. In this way, the opening or closing of the bottom of the brown rice hopper can be controlled by driving the valve plate by the driving member, which is convenient for the actual polished rice processing operation. In this embodiment, an end cover is provided at the upper port of the brown rice hopper.
[0066] Specific embodiment 3: The rest of the structure of this embodiment refers to specific embodiment 2, except that:
[0067] like Figure 1As shown, the bran removal net cylinder 3 is inclinedly distributed, and the bran removal net cylinder 3 extends obliquely upward from the brown rice inlet 3.1 to the polished rice outlet 3.2. During the rotation of the polished rice knife 4, the brown rice is pushed along the feeding part 4.1 to move along the bran removal net cylinder 3 axially to the polished rice outlet 3.2. Since the bran removal net cylinder 3 extends obliquely upward from the brown rice inlet 3.1 to the polished rice outlet 3.2, the mutual friction effect of the rice grains in the polishing chamber can be enhanced, and the time for the rice grains to rub against each other in the polishing chamber can be extended, which can not only improve the polished rice processing effect, but also help to shorten the length of the bran removal net cylinder 3, reduce the volume of the rice polishing machine, and achieve the purpose of improving the polished rice processing effect within a short distance.
[0068] In this embodiment, the inclination angle of the bran removal net cylinder 3 is 8-25 degrees, for example, the inclination angle of the bran removal net cylinder 3 is 10 degrees, 15 degrees or 20 degrees. The inclination angle of the bran removal net cylinder 3 cannot be too large or too small. If the inclination angle of the bran removal net cylinder 3 is too large, it will not only affect the efficiency of the polished rice processing, but also cause excessive friction of the rice grains during the polishing process, which will reduce the nutritional value of the polished rice; if the inclination angle of the bran removal net cylinder 3 is too small, it will not enhance the effect of mutual friction between the rice grains in the polishing chamber. Therefore, this scheme sets the inclination angle of the bran removal net cylinder 3 to 8-25 degrees. In this way, on the one hand, it can enhance the effect and duration of mutual friction between the rice grains in the polishing chamber, which can not only improve the polishing effect, but also help to shorten the length of the bran removal net cylinder 3, reduce the volume of the rice polishing machine, and achieve the purpose of improving the polishing effect in a short distance; on the other hand, it can avoid the problem of excessive friction of rice grains, which reduces the nutritional value of polished rice.
[0069] Specific embodiment 4: The rest of the structure of this embodiment refers to specific embodiment 2 or specific embodiment 3, the difference is that:
[0070] In this embodiment, the bran removal net cylinder 3 can be detachably mounted on the frame of the small automatic rice polishing machine. The bran removal net cylinder 3 is mounted on the frame by bolts or buckles. In this way, after the small automatic rice polishing machine is used for a period of time, the bran removal net cylinder 3 can be removed from the rice polishing machine so as to clean the bran removal net cylinder 3 to improve the use effect and extend the service life.
[0071] In the present embodiment, the rice polishing knife 4 is rotatably mounted on the frame of the small automatic rice polishing machine. In this way, after the small automatic rice polishing machine has been used for a period of time, the bran removal net cylinder 3 and the rice polishing knife 4 can be disassembled from the rice polishing machine to clean the bran removal net cylinder 3 and the rice polishing knife 4 to improve the use effect and extend the service life.
[0072] The above description is only a preferred embodiment of the present invention and does not constitute any limitation to the present invention. Any simple modification, change and equivalent transformation made to the above embodiments according to the technical essence of the present invention shall still fall within the protection scope of the technical solution of the present invention.
