Description

Technical Field

[0001] This invention relates to the field of rice noodle production technology, and in particular to a rice soaking device for producing nutritious rice noodles. Background Technology

[0002] Rice noodles are a type of food made primarily from rice. Their history can be traced back to the Qin Dynasty. According to folklore, they were invented by the Qin army when they marched south to adapt to the southern diet. Later, they gradually developed into a representative delicacy of southern China and Southeast Asia.

[0003] Currently, rice noodles have developed into many categories. Traditional rice noodles use rice as a single ingredient, which has problems such as limited nutrition and weak functional properties. Rice noodles that combine with seafood ingredients are the current mainstream innovation direction in the industry, which can supplement consumers with high-quality protein, dietary fiber, minerals and other scarce nutrients.

[0004] Based on the above, the inventor believes that the current rice noodle processing still requires soaking for a certain period of time to allow the rice to fully absorb water, soften the starch structure, and facilitate subsequent grinding and other processes. Traditionally, after soaking, the rice needs to be transported through pipelines to the rice-water separation process for further processing, and then the filtered rice is sent to the next process. The entire operation is quite lengthy and time-consuming. Therefore, an improved soaking device is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a rice soaking device for the production of nutritious rice flour, which optimizes the traditional soaking and processing mode and improves production efficiency.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a rice soaking device for producing nutritional rice flour, comprising a soaking tank, a rice receiving tray at the outlet of the soaking tank, a water recovery chamber below the rice receiving tray, the outside of the soaking tank being fixed to the placement surface by a mounting bracket, and a feed pipe and a spray nozzle being fixed on the upper surface of the soaking tank, rice being fed into the soaking tank through the feed pipe and then soaking water being provided by the spray nozzle, the outside of the rice receiving tray being connected to a shifting component, and the rice receiving tray being detachably connected to the soaking tank through the shifting component; The bottom of the soaking tank is an inverted cone shape, and the bottom surface of the inverted cone is a flat surface. A circular discharge port is provided on the flat surface. The rice receiving tray includes a cutting component that is detachably connected to the discharge port and a receiving component that is detachably set on the cutting component.

[0007] A further feature of the present invention is that an electromagnetic component is fixedly provided on the bottom surface of the soaking tank, and the material cutting component includes a material cutting column whose outer wall is inserted into the discharge port, and the outer side of the material cutting column is electromagnetically connected to the electromagnetic component through a bonding ring.

[0008] By adopting the above technical solution, the magnetic attraction force generated by the electromagnetic component can stably attract and hold the adhesive ring.

[0010] By adopting the above technical solution, the cutting column can be connected to the connecting pipe in a supporting manner through the connecting ring.

[0011] A further feature of the present invention is that the shifting assembly is arranged symmetrically on the outside of the frame. The shifting assembly includes an adjusting plate whose upper surface is in contact with the frame and an electric push rod whose piston rod is fixedly connected to the adjusting plate. The adjusting plate can be linearly displaced along the height direction of the mounting frame. The adjusting plate and the frame are detachably connected by a docking structure.

[0012] By adopting the above technical solution, it is convenient to remove and install the frame.

[0013] A further embodiment of the present invention is that the docking structure includes a slot formed on the frame and a plug fixed on the adjustment plate, wherein the outer side of the plug is inserted into the slot.

[0014] By adopting the above technical solution, the frame can be stably installed on the adjustment plate and easily removed.

[0015] A further provision of the present invention is that the soaking tank and the mounting frame are connected by a buffer, and the bottom end of the soaking tank is connected to a uniform material component.

[0016] By adopting the above technical solution, the rice is helped to receive a certain uniform vibration force during soaking.

[0017] A further provision of the present invention is that the buffer is provided at two or more locations on the outside of the soaking tank. The buffer includes a protective cover whose bottom end is fixedly connected to the mounting frame and a slider that can slide up and down along the inner wall of the protective cover. The outside of the slider is fixedly connected to the soaking tank, and the bottom end of the slider is fixedly connected to the mounting frame through a first spring.

[0018] By adopting the above technical solution, when the soaking tank is subjected to an external force of vertical displacement, the external force can be synchronously applied by the sliding of the slider inside the protective cover.

[0024] By adopting the above technical solution, the motor can drive the rotating wheel to rotate.

[0025] The beneficial effects of this invention are: Rice is soaked in a soaking tank. When it is time to discharge, the receiving part simply moves the cutting part to quickly separate from the discharge port. The rice-water mixture falls quickly into the filter screen due to gravity, thus quickly separating the soaked rice from the soaking liquid. The filtered rice can then be quickly removed and poured into the next processing step, shortening the time required for rice filtration. At the same time, the soaking water can be quickly recycled, avoiding water waste and promoting environmentally friendly production. In addition, the combination of buffer and uniform material components during rice soaking allows the rice to receive uniform vibration force during soaking, reducing the amount of rice that comes into contact with the soaking water due to stacking, thereby improving the soaking effect.

[0029] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example

[0030] This invention provides a rice soaking device for producing nutritious rice flour, including a soaking tank 1. A rice receiving tray 2 is provided at the discharge end of the soaking tank 1, and a water recovery chamber 3 is provided below the rice receiving tray 2. After the rice is discharged, the rice can be quickly separated from the clean water through the rice receiving tray, and the soaking water can be quickly collected through the water recovery chamber 3. A connecting pipe for connecting to an external pipeline is fixed on the water recovery chamber 3, so that the external water recovery pipeline can be connected to the water recovery chamber 3 through the connecting pipe to facilitate the removal of the soaking water, thereby avoiding excessive water loss during the soaking process. At the same time, it can also facilitate water recycling and save water resources.

[0031] The soaking tank 1 is fixed to the placement surface by the mounting bracket 11 on the outside, and the upper surface of the soaking tank 1 is fixed with a feed pipe 12 and a spray nozzle 13. In practice, the spray nozzle 13 is connected to the soaking water supply pipeline of the production system. After the rice is fed into the soaking tank 1 through the feed pipe 12, the spray nozzle 13 provides soaking water, so that the rice can be soaked stably after being fed into the soaking tank 1, which meets the soaking needs during rice production.

[0032] The outer side of the rice receiving tray 2 is connected to the shifting component 4. The rice receiving tray 2 is detachably connected to the soaking tank 1 through the shifting component 4. By controlling the rice receiving tray 2, the rice after soaking can be discharged quickly and the rice and water can be separated, thereby optimizing the operation mode and improving efficiency.

[0033] Specifically, the bottom of the soaking tank 1 is an inverted cone shape, and the bottom surface of the inverted cone is a plane with a circular discharge port. The rice receiving tray 2 includes a cutting component 21 that is detachably connected to the discharge port and a receiving component 22 that is detachably set on the cutting component 21. The cutting component 21 controls the discharge of the soaked rice, and the receiving component 22 performs quick rice-water separation, thereby completing the quick rice-water separation step after the rice is discharged, shortening the operation time required between the two steps and improving efficiency.

[0034] Furthermore, an electromagnetic component 7 is fixedly provided on the bottom surface of the soaking tank 1. The electromagnetic component 7 is an existing component capable of generating magnetic force. The part that generates magnetic force is a circular ring structure. The top side of the electromagnetic component 7 is fixedly connected to the soaking tank 1, and the bottom side is a planar structure connected to the cutting component 21. At present, electromagnetic technology has been relatively mature. Regarding the specific structure and operation mode of the electromagnetic component 7, those skilled in the art can consult and customize it with professional manufacturers to adapt it to the functions required by this technical solution. The relevant implementation methods will not be described in detail here.

[0035] The material cutting component 21 includes a material cutting column 211 whose outer wall is inserted into the discharge port. The outer side of the material cutting column 211 is in close contact with the discharge port to improve the sealing performance. The outer side of the material cutting column 211 is electromagnetically connected to the electromagnetic component 7 through a bonding ring 212. The upper surface of the bonding ring 212 is in close contact with the lower surface of the electromagnetic component 7. The bonding ring 212 is made of iron, so that after the electromagnetic component 7 generates a magnetic attraction force, it can stably attract the bonding ring 212, thereby improving the sealing performance of the material cutting component 21 by means of traditional magnetic sealing.

[0036] It is worth noting that the top surface of the cutting column 211 has a conical structure to facilitate the centrifugal throwing and discharge of rice along its top surface, thus improving the convenience of discharge.

[0037] Furthermore, a connecting ring 213 is fixedly provided on the outer wall of the cutting column 211. The receiving component 22 includes a frame 221 and a connecting tube 222 whose inner wall is inserted into the cutting column 211. The bottom surfaces of the frame 221 and the connecting tube 222 are fixedly connected by a filter screen 223. The filter screen 223 can be made of alloy steel and has strong supporting rigidity. The mesh size of the filter screen 223 is smaller than the size of rice to facilitate filtering out the rice and allowing the soaking water to fall into the water recovery chamber 3. The top end of the connecting tube 222 abuts against the connecting ring 213, so that the cutting column 211 can be connected to the connecting tube 222 in a supporting manner through the connecting ring 213, so that the connecting tube 222 provides a supporting force to prevent the cutting column 211 from falling.

[0038] Specifically, the shifting component 4 is arranged symmetrically on the outside of the frame 221. The shifting component 4 includes an adjusting plate 41 whose upper surface is in contact with the frame 221 and an electric push rod 42 whose piston rod is fixedly connected to the adjusting plate 41. During normal use, the bottom surface of the frame 221 is placed on the adjusting plate 41. The adjusting plate 41 provides support for the frame 221. Therefore, when the adjusting plate 41 moves up or down, it will drive the frame 221 to move up and down synchronously.

[0039] The adjusting plate 41 can be linearly displaced along the height direction of the mounting frame 11. In practice, a sliding groove 44 is provided on the adjusting plate 41. A guide bar 45 extending along its height direction is fixedly provided on the side of the mounting frame 11 near the adjusting plate 41. The inner wall of the sliding groove 44 is slidably connected to the guide bar 45, so that the adjusting plate 41 can slide stably along the guide bar 45.

[0040] The adjustment plate 41 and the frame 221 are detachably connected by a docking structure to facilitate the removal and installation of the frame 221.

[0041] Specifically, the docking structure includes a slot 224 opened on the frame 221 and a plug 43 fixed on the adjustment plate 41. The outer side of the plug 43 is inserted into the slot 224, so that the frame 221 can be stably installed on the adjustment plate 41 and easily removed.

[0042] In this technical solution, when it is necessary to discharge the soaked rice, the electromagnetic component 7 is first de-energized. At this time, the bottom of the cutting column 211 is supported only by the frame 221 and the connecting pipe 222. Subsequently, the adjusting plate 41 can be moved down by the electric push rod 42. After the frame 221 moves down, the cutting column 211 can move down and separate from the discharge port, so that the rice and soaking water in the soaking tank 1 can be centrifugally thrown downward along the top surface of the cutting column 211, allowing the rice to be filtered through the filter screen. The soaking water falls into the water recovery chamber 1. After that, the cutting column 211 is reset upward and repositioned with the electromagnetic component 7. At this time, the adjusting plate 41 can move the frame 221 downward, so that the connecting tube 212 is separated from the cutting column 221. Then the frame 221 can be moved off the adjusting plate 41, and the filtered soaked rice can be moved and poured into the next processing step. After that, the frame 221 is reset and installed on the adjusting plate 41. The adjusting plate 41 is then moved upward so that the connecting tube 222 can be inserted into the cutting column 211, and the connecting ring 213 can come into contact with the connecting tube 222.

[0043] It is worth noting that when rice is thrown out of the discharge port, some rice grains will fall onto the affix ring 212. When the affix ring 212 needs to be reset, workers can first manually wipe and clean it to avoid rice grains and water stains on the contact surface when the affix ring 212 comes into contact with the electromagnetic component 7. Example

[0044] This invention provides a rice soaking device for producing nutritious rice flour. Unlike embodiment one, the soaking tank 1 is connected to the mounting frame 11 by a buffer 5, and the bottom of the soaking tank 1 is connected to a uniform material 6. The uniform material 6 helps the rice to receive a certain uniform vibration force during soaking, preventing the rice from being piled up too long and improving the contact effect between the rice and the soaking water.

[0045] Specifically, the buffer 5 is provided in two or more places on the outside of the soaking tank 1 to improve the buffering stability of the soaking tank 1 after being subjected to force. The buffer 5 includes a protective cover 51 whose bottom end is fixedly connected to the mounting bracket 11 and a slider 52 that can slide up and down along the inner wall of the protective cover 51. The outside of the slider 52 is fixedly connected to the soaking tank 1, and the bottom end of the slider 52 is fixedly connected to the mounting bracket 11 through the first spring 53. This allows the slider 52 to be synchronously subjected to the external force of vertical displacement when the soaking tank 1 is subjected to the external force through the sliding of the slider 52 in the protective cover 51, and to be buffered by the elastic tension of the first spring 53, and to be easily reset by the spring.

[0046] Furthermore, a side frame 14 is fixedly connected to the outside of the mounting frame 11. The material leveling component 6 includes multiple material leveling rings 61 that abut against the conical structure at the bottom of the soaking tank 1. The material leveling rings 61 are fixedly connected to each other by a bracket 62. The material leveling rings 61 are slidably engaged with the side frame 14 through a sliding frame. The outside of the sliding frame is connected to a driving component. The driving component drives the sliding frame to move, so that the material leveling rings 61 can move synchronously with the sliding frame and apply a material leveling impact force to the outside of the soaking tank 1, thereby improving the rice soaking effect.

[0047] Specifically, the uniform feeding ring 61 includes a ring body 611 that is coaxially fitted with the soaking tank 1. The upper surface of the ring body 611 is fixed with a protrusion 612 whose top end abuts against the soaking tank 1. There are two or more protrusions 612, so that the protruding ring 612 can repeatedly contact and strike the outer wall of the soaking tank 1 to achieve uniform feeding of rice in the soaking tank 1.

[0048] The sliding frame includes a support frame 631 fixedly connected to the outer side of the ring 611. The support frame 631 is slidably engaged with the side frame 14 via a sliding rod 632. A rail 141 is provided on the side frame 14. The sliding rod 632 slides vertically up and down along the rail 141. Limiting plates 633 are fixedly provided on both the inner and outer sides of the side frame 14. The adjacent surfaces of the limiting plates 633 are in sliding contact with the side frame 14, so that the sliding rod 632 can slide stably up and down.

[0049] In practice, the slide bar 632 is provided with a reset structure. The reset mechanism includes two mounting plates 634 that are fixed to the limiting plate 633 and the side plate 14 respectively. A second spring 635 is fixedly installed between the two mounting plates 634. When the slide bar 632 moves down, the second spring 635 will be compressed and generate an elastic force to provide upward reset for the slide bar 632.

[0050] The driving component includes a pressure rod 641 whose outer wall slides in contact with the slide rod 632. Four pressure rods 641 are equidistantly arranged on the rotating wheel 642. The pressure rods 641 are fixedly installed on the outside of the rotating wheel 642. The rotating wheel 642 is driven to rotate by a motor 643. The motor 643 is fixedly installed on the side plate 14, and the output shaft of the motor 643 passes through the side plate 14 and is fixedly connected to the rotating wheel 642. Thus, the motor 643 can drive the rotating wheel 642 to rotate, causing the pressure rod 641 to move and apply downward pressure to the slide rod 632. After the slide rod 632 moves down to the height where the pressure rod 641 separates, the slide rod 632 is reset by the second spring 635. Then, the next pressure rod 641 causes the slide rod 632 to move down again, realizing the repeated up and down movement of the slide rod 632.

[0051] When the slide bar 632 moves, it will drive the uniform material ring 61 to move synchronously, so that the protrusion 612 first separates from the soaking tank 1 downwards and then contacts the soaking tank 1 to strike it. This is repeated, so that the rice soaking in the soaking tank 1 can receive uniform material vibration force, reduce the stacking of rice, and improve the soaking effect.
