Description

Technical Field

[0001] The invention relates to the technical field of rice processing, in particular to a processing technology and a preparation device for polygonatum rice. Background Art

[0002] Polygonatum sibiricum is a medicinal herb with rhizomes, which can nourish qi and yin, strengthen spleen, moisten lungs and benefit kidneys. It is an ideal nourishing product for the elderly, without the side effects of strong nourishing and warming products. In addition, Polygonatum sibiricum can lower blood pressure and blood sugar, increase coronary blood flow, reduce blood lipids and delay atherosclerosis.

[0003] Rice is the main food source for people in most parts of China. Currently, there is also polygonatum rice on the market that uses polygonatum extract to enhance the nutrition of rice and improve the health value of rice. In the preparation process of polygonatum rice, it is usually necessary to prepare polygonatum extract, prepare nutrient solution, spray nutrient solution, dry rice and screen rice particles to ensure that the final prepared polygonatum rice has good quality.

[0004] There is a patent application number CN202020663815.9 for a Huangjing rice powder processing and screening device, which shows the screening process of Huangjing rice preparation, including: "Connect the powered wire 7 to the external power supply to provide power to the device, and then press the switch A7, the switch A7 transmits the signal to the pumping pump 12, the pumping pump 12 discharges the Huangjing rice powder into the screening box through the discharge pipe 11 through the pumping pipe 13, and completes the feeding". Although the above scheme effectively avoids the overflow of Huangjing rice powder during the feeding process, when the pumping pump puts the Huangjing rice powder into the screening box through the discharge pipe, since the feed inlet is only located directly above the screening box, the sucked Huangjing rice will fall directly onto the screen of the screening box, which makes the qualified rice and the inferior rice fall on the central area of ​​the screen in a piled state at the same time. Due to the limited density of the sieve holes located in the center of the screen, this may cause some inferior rice to enter the collection bucket without screening along with the qualified rice, thereby reducing the overall screening quality of Huangjing rice. To this end, we propose a Huangjing rice processing technology and preparation device. Summary of the invention

Furthermore, in the process of continuous resistance, the ball will gradually move to the bottom of the protrusion. In this state, the vibrating screen will be lifted up a short distance. In continuous rotation, the ball will slide from the other side of the protrusion, causing the vibrating screen to drop down a short distance. In this process, the spring will be pulled back and switched between tension and compression. In this reciprocating manner, the vibrating screen will produce a continuous vibration effect under the intermittent resistance of the ball and the protrusion. The cooperation between the vibration component and the divergence component further enhances the screening effect of the Polygonatum odoratum rice and improves the overall screening quality of the rice.

[0022] 2. In the present invention, by setting a secondary screening component, when the qualified rice partially mixed with the secondary rice passes through the discharge port, the belt 2 located outside the main shaft will drive the fan blades outside the connecting shaft to rotate, and the suction force generated by the fan blades will drive the lighter secondary rice mixed in the qualified rice to be sucked into the cylinder body, and then these secondary rice will pass through the top of the cylinder body and enter the interior of the connecting cylinder, and finally be discharged at the end of the connecting cylinder, and enter the interior of the vibrating screen of the fuselage again for secondary screening. By using the secondary screening component, the screening of the Polygonatum odoratum rice is strictly subjected to secondary screening, thereby further enhancing the overall rice screening quality.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not 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.

[0037] See also Figure 1-12The present invention provides a technical solution: a processing technology and a preparation device for polygonatum rice. The solution solves the problems raised in the background technology. The solution makes corresponding improvements to the above problems, including a body 1, a plurality of supports 2 are provided at the bottom of the body 1 to support it, and the ends of the supports 2 are fixedly connected to the body 1, a feed pipe 3 for the polygonatum rice to flow is provided above the body 1, the feed pipe 3 runs through the body 1, an extraction pump 4 is provided outside the feed pipe 3, and the extraction pump 4 can suck the polygonatum rice to be screened into the body 1 through the feed pipe 3, and a vibration screen 5 is provided inside the body 1 to receive the polygonatum rice, the outer wall of the vibration screen 5 is in contact with the inner wall of the body 1, and the vibration screen 5 can slide up and down inside the body 1, the vibration screen 5 includes a raised part 51 and a flat part 52, and a plurality of sieve holes 6 for sub-rice to pass through are provided on the surface of the vibration screen 5, and the size of the sieve holes 6 can only allow sub-rice to pass through, which meets the screening index of sub-rice and qualified rice, and a dispersion group for breaking up the rice is provided above the vibration screen 5. The diverging assembly 7 in this scheme includes a main shaft 71 located inside the vibrating screen 5, a connecting rod 72 is provided outside the main shaft 71, the connecting rod 72 is rotatably connected to the main shaft 71, one end of the connecting rod 72 is fixedly connected to the inner wall of the fuselage 1, the main shaft 71 passes through the vibrating screen 5 and is rotatably connected thereto, one end of the main shaft 71 is provided with a conical screen 73 and is fixedly connected thereto, a belt 74 is provided on the surface of the main shaft 71, the belt 74 passes through the fuselage 1, and a motor 75 is provided on one side of the fuselage 1. The rotating shaft of the motor 75 is located on the inner wall of the belt 1 74 and drives it to rotate. The belt 1 74 can simultaneously drive the main shaft 71 and the rotating shaft of the motor 75 to rotate. A fixing frame 76 is provided on the outside of the motor 75 and is fixedly connected thereto. One side of the fixing frame 76 is fixedly connected to the outer wall of the fuselage 1. The outer wall of the conical screen 73 is provided with a plurality of oblique bars 8 distributed symmetrically with the center. The bottom of the oblique bars 8 is fixedly connected to the conical screen 73. Two adjacent oblique bars 8 form a divergent ditch 9, and the divergent ditch 9 is for the polygonatum rice to flow.

[0038] The staff can start the extraction pump 4 to suck the Huangjing rice to be screened into the body 1 through the feed pipe 3. After the rice falls from the top of the body 1, it will directly fall on the top of the conical screen 73. The fallen rice will diverge in all directions along the conical screen 73, thereby preliminarily breaking up the rice. At the same time, the staff can turn on the motor 75 on one side of the body 1, so that the motor 75 shaft drives the belt 1 74 and the main shaft 71 located at the center of the vibrating screen 5 to rotate, and the main shaft 71 will drive the conical screen 73 to enter. The vibrating screen 5 rotates, so the fallen rice will flow through the divergent ditch 9 formed by the two oblique bars 8, and with the centrifugal force of the conical screen 73, it will further diverge into the fuselage 1 from all directions. Due to the inclined effect of the raised portion 51 of the vibrating screen 5, the rice on the vibrating screen 5 will automatically slide to the straight portion area, thereby enhancing the divergent effect of the rice. Through the divergent component 7, the polygonatum rice to be screened can be evenly distributed on the surface of the vibrating screen 5, which is beneficial to improving the overall screening quality of the polygonatum rice.

[0039] Furthermore, a vibration assembly 10 for driving the vibration screen 5 to vibrate up and down is provided inside the fuselage 1, and the vibration assembly 10 includes a plurality of springs 101 located at the bottom of the vibration screen 5, one end of the spring 101 is provided with an annular strip 102, the outer wall of the annular strip 102 is fixedly connected to the inner wall of the fuselage 1, and the two ends of the spring 101 are respectively fixedly connected to the vibration screen 5 and the annular strip 102, and a plurality of protrusions 103 are further provided at the bottom of the vibration screen 5, and the plurality of protrusions 103 are all fixedly connected to the bottom of the vibration screen 5, and both sides of the protrusions 103 are arc-shaped, and a connecting block 104 is provided on the outer wall of the main shaft 71 and fixedly connected thereto, and a fixing rod 105 is provided on one side of the connecting block 104, and one end of the fixing rod 105 is provided with a sphere 106 and fixedly connected thereto, and one end of the sphere 106 is in contact with the bottom surface of the vibration screen 5;

[0040] When the motor 75 drives the main shaft 71 to rotate, the rotating main shaft 71 will drive the connecting block 104 and the fixed rod 105 and the ball 106 above the connecting block 104 to rotate together. During the rotation process, the surface of the ball 106 located at one end of the fixed rod 105 will resist each other with the arc surface area on the side of the protrusion 103. Further, during the continuous resistance process, the ball 106 will gradually move to the bottom of the protrusion 103. In this state, the vibration screen 5 will be lifted up a short distance. During the continuous rotation, the ball 106 will slide from the other side of the protrusion 103, thereby causing the vibration screen 5 to drop down a short distance. During this process, the spring 101 will be pulled back and switched between the tension and compression states. In this reciprocating manner, the vibration screen 5 will produce a continuous vibration effect under the intermittent resistance of the ball 106 and the protrusion 103. Through the cooperation between the vibration component 10 and the divergence component 7, the screening effect of the Polygonatum odoratum rice is further enhanced, and the overall screening quality of the rice is improved.

[0041] In addition, a discharge port 11 is provided on the surface of the fuselage 1, and an anti-overflow component 12 is provided on the inner wall of the fuselage 1. The anti-overflow component 12 is used to reduce the direct discharge of rice from the discharge port 11 without screening. The anti-overflow component 12 includes a baffle 121 for blocking the discharge port 11, and one end of the baffle 121 is shaped as an inclined surface. A fixed block 122 is provided above the baffle 121, and the bottom of the fixed block 122 is fixedly connected to the baffle 121. A spring 2 123 is provided on one side of the fixed block 122, and a fixed block 2 124 is provided at one end of the spring 2 123. Both ends of the spring 2 123 are fixedly connected to the fixed block 122 and the fixed block 2 124 respectively. One side of the fixed block 2 124 is fixedly connected to the inner wall of the fuselage 1, and a connecting rod 2 125 is provided inside the fixed block 2 124. The connecting rod 2 125 is slidably connected to the fixed block 2 124, and one end of the connecting rod 2 125 The main shaft 71 is fixedly connected to the baffle 121, and a connecting ring 126 is provided on the outside of the main shaft 71. A limiting groove 20 is provided inside the main shaft 71 for the connecting ring 126 to slide up and down. The connecting ring 126 is slidably connected to the main shaft 71, and the connecting ring 126 can rotate together with the main shaft 71. The limiting groove 20 provides a sufficient sliding range for the connecting ring 126, so that when the vibrating screen 5 vibrates, the connecting ring 126 has enough sliding space. The bottom of the connecting ring 126 is in contact with the vibrating screen 5. A connecting rod 3 127 is provided on the outside of the connecting ring 126 and is fixedly connected thereto. One end of the connecting rod 3 127 is provided with a scraper 128 for breaking up the rice on the vibrating screen 5. One end of the connecting rod 3 127 is fixedly connected to the scraper 128. One end of the scraper 128 is provided with an arc plate 129 and is fixedly connected thereto. One end of the arc plate 129 is shaped as an inclined surface.

[0042] When the main shaft 71 rotates, the main shaft 71 will drive the connecting ring 126 to rotate, and then the connecting ring 126 will drive the connecting rod 3 127 and the scraper 128 to rotate on the sieve plate. The rotating scraper 128 can, on the one hand, break up the Huangjing rice on the vibrating screen 5, and on the other hand, the scraper 128 can also effectively gather the rice on the vibrating screen 5 and gradually push it toward the discharge port 11. In this process, the inclined surface of the arc plate 129 on one side of the scraper 128 will collide with the inclined surface of the baffle 121. The second spring 123 will resist each other, and then under the resistance of the inclined surfaces of the two, the baffle 121 will gradually rise, and the spring 123 will be in a compressed state. In this state, the discharge port 11 is in an open state, and then the scraper 128 can push the rice out of the discharge port 11 until the top of the arc plate 129 and the bottom of the baffle 121 lose their resistance, and the elastic force of the spring 123 will make the baffle 121 resist the discharge port 11 again, so as to prevent some unscreened inferior rice from being discharged from the discharge port 11, resulting in a decrease in the overall screening quality of the Polygonatum odoratum rice.

[0043] In addition, a secondary screening component 13 for re-screening the rice located at the discharge port 11 is provided on one side of the fuselage 1, and the secondary screening component 13 includes a cylinder 131 located on one side of the fuselage 1, a connecting shaft 132 is provided inside the cylinder 131, and a connecting rod 133 is provided on the outer wall of the connecting shaft 132, and the connecting rod 133 is rotatably connected to the connecting shaft 132, and one end of the connecting rod 133 is fixedly connected to the inner wall of the cylinder 131, and a belt 134 is further provided on the outer wall of the connecting shaft 132, and the belt 134 is located on the outer wall of the main shaft 71, and the belt 134 can drive the main shaft 71 and the connecting shaft 132 to rotate at the same time, and the diameter of the main shaft 71 is larger than the diameter of the connecting shaft 132, and a fan blade 135 is provided on the outside of the connecting shaft 132 and is fixedly connected thereto. Since the diameter of the main shaft 71 is larger than the diameter of the connecting shaft 132, the rotation speed of the connecting shaft 132 transmitted by the belt 134 will be greater than the rotation speed of the main shaft 71, and then ... The fixedly connected fan blades 135 will have enough wind force to suck the lighter sub-meters located at the discharge port 11 into the interior of the cylinder 131 and the connecting cylinder 136. A connecting cylinder 136 is provided at one end of the cylinder 131 and is connected to each other. The connecting cylinder 136 passes through the fuselage 1 and is fixedly connected to it. The bottom of the cylinder 131 is located just above the discharge port 11. A cover 14 is provided at one end of the cylinder 131 to shield its port. A fixed shaft 15 is provided inside the cover 14 and is fixedly connected to it. A connecting block 2 16 is provided outside the fixed shaft 15. The connecting block 2 16 is rotatably connected to the fixed shaft 15. One side of the connecting block 2 16 is fixedly connected to the outer wall of the cylinder 131. A cover 2 17 is also provided outside the fixed shaft 15 and is fixedly connected to it. The cover 2 17 is located at the bottom of the cylinder 131. A plurality of fine holes 18 are provided on the surface of the cover 2 17 for dust to pass through. A handle 19 is also provided outside the fixed shaft 15 and is fixedly connected to it.

[0044] When the qualified rice partially mixed with secondary rice passes through the discharge port 11, the belt 134 located outside the main shaft 71 will drive the connecting shaft 132 to rotate, and then drive the fan blades 135 outside the connecting shaft 132 to rotate. The suction force generated by the fan blades 135 will drive the lighter secondary rice mixed in the qualified rice to be sucked into the cylinder 131, and then these secondary rice will pass through the top of the cylinder 131 and enter the interior of the connecting cylinder 136, and finally be discharged from the end of the connecting cylinder 136, and enter the vibrating screen 5 of the fuselage 1 again for secondary screening. The secondary screening component 13 is used to perform strict secondary screening on the Huangjing rice, and further On the other hand, when the screening quality of the rice reaches the qualified index, the staff can rotate the fixed shaft 15 through the handle 19 to rotate the cover body 17 at one end of the fixed shaft 15 to cover the bottom of the cylinder 131. In this state, the cover body 14 will be separated from the cover on the top of the cylinder 131. Since the diameter of the pores 18 on the surface of the cover body 17 is small, only some dust with a small diameter can pass through. Therefore, part of the dust of the qualified rice discharged through the discharge port 11 can be sucked out and finally discharged to the outside from the opening at the uppermost end of the cylinder 131, which is beneficial to improving the final screening quality of the Polygonatum sibiricum rice.

[0045] A processing technology for a polygonatum rice preparation device comprises the following steps:

[0046] S1: The rice to be screened is fed into the machine body 1 through the feed pipe 3 by the extraction pump 4;

[0047] S2: Start the motor 75, so that the belt 1 74 drives the main shaft 71 to rotate, and then drives the conical screen 73 at one end of the main shaft 71 to rotate. The rotating conical screen 73 will effectively scatter the fallen rice in all directions;

[0048] S3: The rotating main shaft 71 drives the ball 106 at one end of the fixed rod 105 to resist the protrusion 103, thereby driving the vibrating screen 5 to shake up and down, and effectively screen the rice;

[0049] S4: The qualified rice after screening is discharged from the discharge port 11, and the main shaft 71 drives the belt 2 134 to transmit, so that the connecting shaft 132 and the fan blade 135 rotate, and the lighter secondary rice at the discharge port 11 is sucked out, and enters the interior of the fuselage 1 again through the cylinder 131 and the connecting cylinder 136 for secondary screening.
