Description

Technical Field

[0001] This invention relates to the field of rice soaking equipment technology, and in particular to a rice soaking equipment and process for a pre-processed rice product production line. Background Technology

[0002] In the industrial production of rice-based foods such as rice noodles, rice vermicelli, rice cakes, and instant rice, rice, as the main raw material, needs to be soaked before processing. This allows the rice to absorb an appropriate amount of water, softens the grain structure, and removes light impurities from the rice, facilitating subsequent cooking or shaping processes. Traditional soaking methods often involve using static water tanks or simple containers. During this process, rice is manually poured into a fixed container, water is added, and the mixture is left to stand for several hours until the grains absorb water and swell. After this, the rice is drained and used.

[0003] However, during the rice soaking process, light impurities should float to the surface for separation, but due to the excessively high feeding density, a large number of rice grains sink to form a dense layer, causing some impurities to be pressed to the bottom or mixed in, making it difficult for them to float effectively. Current methods of removing impurities mainly rely on manual netting or fixed overflow outlets for surface skimming, which can only remove a small amount of floating impurities and is ineffective against impurities trapped at the bottom. If increased stirring is used to promote the floating of impurities, it can easily cause violent friction between rice grains, resulting in grain breakage, starch dissolution, and consequently, increased slurry viscosity, uneven sedimentation, affecting the stability of subsequent cooking and shaping processes, and reducing the consistency of product taste and quality.

[0009] Furthermore, it is particularly preferred that the fixing rod is provided with two symmetrically distributed first sliding blocks, the upper first sliding block being slidably connected to the adjacent fixing rod, and the lower first sliding block being fixedly connected to the adjacent fixing rod. A second tension spring is fixedly connected between the fixing rod and the first sliding block near the sliding plate.

A second spring limiting pin is provided inside the fixed shell, and the second spring limiting pin is used to lock the first sliding block.

[0010] Furthermore, it is particularly preferred that the connecting frame is fixedly connected with a ring-shaped array of extrusion pins, each extrusion pin corresponding to a first spring limiting pin, and the extrusion pin is used to extrude the corresponding first spring limiting pin.

[0014] A rice soaking process for a pre-processed rice product production line, characterized by the following specific steps according to the aforementioned rice soaking device for a pre-processed rice product production line: Step 1: Before soaking the rice, put the rice into the filter cloth, then put the filter cloth into the rotating tank and add water to the filter cloth; Step 2: Once the water level reaches the required amount, the rice needs to be soaked for the specified time. Step 3: After the rice has been soaked, turn on the electric control valve to connect the rotating tank to the outside through the connecting pipe. The telescopic end of the electric push rod drives the sliding plate to rise, so that light impurities are squeezed out. Step 4: After the light impurities have been removed, close the electric control valve, and the drive unit will rotate the rotating tank 180° to invert the rice. Then, the drive unit will rotate the rotating tank 180° in the opposite direction. Step 5: After the rice has finished soaking, the telescopic end of the electric push rod moves down, switching to the mode for treating the residual moisture in the rice. Step 6: During the process of treating the residual moisture in the rice, the telescopic end of the electric push rod drives the sliding plate to move upward. The sliding plate clamps the filter cloth through the squeezing column, causing the lower part of the filter cloth to twist as it is lifted upward. Step 7: When the sliding plate moves down rapidly, it disengages from the filter cloth, the filter cloth resets, and the residual water in the rice is shaken out; Step 8: After removing the residual moisture from the rice, remove the rice.

[0015] The beneficial effects are as follows: This invention uses a sliding plate to move inside a rotating tank, raising the water and rice. The rising liquid level pushes the light impurities floating on the surface into the connecting pipe for discharge, simulating the principle of "pressing a needle tube to release air" to achieve automatic impurity discharge. After discharge, the electric control valve closes the connecting pipe to seal the tank. The drive component drives the tank to rotate, causing the rice to flip and turn upside down, breaking the dense layer, releasing the bottom impurities and promoting their floating to the surface, creating conditions for the discharge of subsequent impurities. The entire process does not require vigorous stirring, reducing rice grain damage and starch dissolution, and ensuring the stability of subsequent processes. During the rice soaking process, the rice is first placed inside the filter cloth to prepare for the removal of residual water from the rice. When it is necessary to remove the residual water from the rice, the sliding plate drives the fixed column to rotate and rise upwards. The squeezing column clamps the filter cloth, simulating the action of grabbing the bottom of a plastic bag and twisting it. After the sliding plate moves to its limit position, it quickly returns to its original position and gets out of contact with the filter cloth. Through the return of the filter cloth, the rice is rotated in the rotating tank, which shakes out the residual water from the rice and shortens the time for removing water from the rice.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] The base frame 1 is equipped with a control terminal, and all electrical components mentioned in this invention are electrically connected to the control terminal.

[0020] To address the problem that existing equipment, when soaking rice, forms a dense layer due to overly dense feeding, causing some light impurities to be pressed to the bottom and unable to float, and that current scooping methods can only remove surface impurities and are difficult to completely remove them, while increasing stirring to help them float can easily lead to rice grain damage and starch dissolution, affecting the properties of the slurry and subsequent processes, and reducing product quality; Example 1 A rice soaking device for a pre-processed rice product production line, please refer to... Figures 1-7The system includes a base frame 1, a rotating tank 2 rotatably connected to the base frame 1, and a drive unit 3 for rotating the rotating tank 2. The drive unit 3 consists of a motor and a gear transmission box. A sealing cover 4 is detachably connected to the upper side of the rotating tank 2. A frustum-shaped groove is provided inside the sealing cover 4 to guide light impurities. This frustum-shaped groove is located below the connecting pipe 6. The sealing cover 4 is fixedly connected to and communicates with the connecting pipe 6. In this invention, there are two connecting pipes 6. The connecting pipes 6 are fixedly connected to and communicate with an electric control valve 7. An electric push rod 8 is provided at the bottom of the base frame 1. In this invention, there are two electric push rods 8. A sliding plate 9 is provided inside the rotating tank 2. In this embodiment, the sliding plate 9 is slidably connected to the rotating tank 2. The telescopic end of the electric push rod 8 is used to push the sliding plate 9 inside the rotating tank 2. The sliding plate 9 is fixedly connected to the bottom of the rotating tank 2 and connected to a drain pipe 10. The drain pipe 10 is provided with a stretchable corrugated part. By moving the sliding plate 9 inside the rotating tank 2, the water and rice inside the rotating tank 2 are both lifted upwards. By using the rise in liquid level, light impurities floating on the surface rise with the liquid level and enter all the connecting pipes 6, achieving automatic discharge. By simulating the way of pressing the needle tube to release air, the liquid level is raised and light impurities are driven to be discharged autonomously. The connecting pipes 6 are blocked by the electric control valve 7, making the rotating tank 2 a sealed tank. Then, the rotating tank 2 is driven to rotate by the driving component 3, causing the rice to flip and turn upside down, thereby breaking the dense structure of the rice layer, causing the light impurities stuck at the bottom to break away from the rice grains and float to the liquid surface, creating conditions for the discharge of impurities when the liquid level rises later.

[0021] Working principle: Before soaking the rice, the staff first removes the sealing cover 4, puts the required amount of rice and water into the rotating tank 2, and then installs the sealing cover 4 back into its original position. Then, the staff connects the upper side of the electric control valve 7 to the external collection tank (this tank is used to collect the water after the rice is soaked). At that time, as the rice soaking time increases, some light impurities in the rice will float to the surface of the liquid.

[0022] When it is necessary to treat impurities on the liquid surface, the staff opens the electric control valve 7 through the control terminal, so that the rotating tank 2 is connected to the outside through the connecting pipe 6. Then, the sliding plate 9 is lifted upward by controlling the extension end of the two electric push rods 8. As the sliding plate 9 moves upward, the water and rice in the rotating tank 2 are lifted upward. Under the action of the rising liquid level, the light impurities floating on the surface rise with the liquid level and enter all the connecting pipes 6, and then flow into the external collection tank to achieve the collection of light impurities floating on the surface.

[0023] After the light impurities on the liquid surface are removed, the connecting pipe 6 is sealed by the electronically controlled valve 7, making the rotating tank 2 a sealed tank. Then, the rotating tank 2 is driven to rotate 180° by the drive component 3, causing the rice to flip over and break the dense structure of the rice layer. This allows the light impurities stuck at the bottom to detach from the rice grains and float to the liquid surface, creating conditions for the impurities to be discharged when the liquid level rises. After the rotating tank 2 rotates 90°, the rotating tank 2 is driven to rotate in the opposite direction by the drive component 3, so that the rotating tank 2 returns to the state shown in the attached figure. At this time, the process of removing light impurities from the liquid surface can be repeated. After the rice has been soaked, the staff first opens the drain pipe 10 to drain the water in the rotating tank 2. Finally, the staff takes out the rice.

[0024] When rice is soaked in a container, it is usually drained along with water through a drain outlet at the bottom of the container. During this process, the static pressure of the upper rice grains and water is concentrated in the area of ​​the bottom drain pipe (existing drainage section), causing the rice grains near the drain outlet to be subjected to greater pressure, making them prone to crushing and affecting the integrity of the rice grains. At the same time, in the initial stage of drainage, the water flow carries the rice grains to the drain outlet rapidly, easily causing rice grain accumulation and blockage. This not only affects the discharge efficiency but also leads to equipment malfunctions or the need for frequent shutdowns for cleaning, increasing labor intensity and reducing production continuity. In addition, clearing blockages often requires increasing water pressure or manual intervention, further exacerbating the risk of rice grain breakage, which is detrimental to the stable production of high-quality rice products. To solve the above problems, this invention is described in the following paragraphs: Example 2 Based on Example 1, please refer to Figure 3 and Figure 4 The sealed cover 4 is fixed with a filter cloth 5 located inside the rotating tank 2, in preparation for the subsequent removal of residual moisture in the rice. The sliding plate 9 is used to push the filter cloth 5.

[0025] Please refer to Figure 4 and Figures 6-10A fixed cylinder 11 is fixedly connected to the lower side of the rotating tank 2. The drain pipe 10 passes through the fixed cylinder 11. The fixed cylinder 11 is rotatably connected to a connecting frame 12. The connecting frame 12 is slidably connected to a connecting cylinder 13. A first tension spring is fixedly connected between the lower side of the connecting cylinder 13 and the fixed cylinder 11. The first tension spring is used to drive the connecting cylinder 13 to reset. The connecting cylinder 13 is provided with a ring-shaped array of first spring limiting pins 14. The fixed cylinder 11 is provided with a ring-shaped array of guide grooves. The first spring limiting pins 14 correspond one-to-one with the guide grooves on the fixed cylinder 11. Pin 14 is slidably connected to the corresponding guide groove on the fixed cylinder 11. In this invention, there are two first spring limiting pins 14 and two guide grooves in the fixed cylinder 11. The guide grooves are spiral-shaped and are used to drive the connecting cylinder 13 to rotate relative to the fixed cylinder 11 during the sliding of the first spring limiting pins 14 along the guide groove in the fixed cylinder 11. The connecting cylinder 13 is fixedly connected to the connecting frame 15. The connecting frame 15 is fixedly connected to the connecting ring 16 located in the rotating tank 2. The sliding plate 9 is fixedly connected to the fixed rods 17 distributed in a ring array. The fixed rods 17 pass through the connecting ring 16.

[0026] Please refer to Figure 7 and Figure 10 The fixed rod 17 is provided with two symmetrically distributed first sliding blocks 18. The upper first sliding block 18 is slidably connected to the adjacent fixed rod 17, and the lower first sliding block 18 is fixedly connected to the adjacent fixed rod 17. The first sliding block 18 is frustum-shaped. The diameter of the upper first sliding block 18 gradually increases from top to bottom, and the diameter of the lower first sliding block 18 gradually increases from bottom to top. The maximum diameter of the upper first sliding block 18 is greater than the maximum diameter of the lower first sliding block 18. The fixed rod 17 is fixedly connected to the first sliding block 18 near the sliding plate 9. There is a second tension spring, which is used to drive the adjacent first sliding block 18 to reset. The connecting ring 16 is fixedly connected to a fixed shell 19 distributed in a ring array. The fixed rod 17 corresponds to the fixed shell 19 one by one. The fixed rod 17 passes through the corresponding fixed shell 19. A second spring limiting pin 20 is provided inside the fixed shell 19. The second spring limiting pin 20 is used to lock the first sliding block 18. The upper side of the second spring limiting pin 20 is provided with an inclined surface. When the second spring limiting pin 20 is located between two first sliding blocks 18, the fixed shell 19 and the fixed rod 17 move synchronously.

[0027] Please refer to Figure 9 and Figure 10The connecting frame 12 is fixedly connected with a ring-shaped array of pressing pins 21, each corresponding to a first spring limiting pin 14. The pressing pins 21 are used to press the corresponding first spring limiting pins 14. In this invention, there are two pressing pins 21, each with an inclined surface on its lower side. The first spring limiting pins 14 can be made of a magnetically adsorbable material. The connecting frame 12 is slidably connected with a ring-shaped array of second sliding blocks 22, which are magnets. A spring is provided between the second sliding block 22 and the connecting frame 12. The second sliding block 22 corresponds to the first spring limiting pin 14. Correspondingly, the second sliding block 22 is used to adsorb the first spring limiting pin 14. Under normal circumstances, the distance between the second sliding block 22 and the corresponding first spring limiting pin 14 is far, and the second sliding block 22 does not adsorb the first spring limiting pin 14. When the first spring limiting pin 14 contacts the extrusion pin 21, it is extruded by the extrusion pin 21, causing the first spring limiting pin 14 to disengage from the corresponding guide groove on the fixed cylinder 11, and causing the first spring limiting pin 14 to adsorb with the second sliding block 22. The sliding plate 9 is fixedly connected to the extrusion column 24, which is provided with a protrusion for holding the filter cloth 5.

[0028] Please refer to Figure 6 The sliding plate 9 is fixedly connected to an air bladder 25 that contacts the inside of the rotating tank 2. In this embodiment, the sliding plate 9 slides inside the rotating tank 2 via the air bladder 25. During the process of removing light impurities from the rice, the pressure inside the air bladder 25 is high, the friction between the air bladder 25 and the rotating tank 2 is high, and the two remain sealed. During the process of treating residual moisture in the rice, the pressure inside the air bladder 25 is low, the friction between the air bladder 25 and the rotating tank 2 is low, but the two still remain sealed. The telescopic end of the electric push rod 8 is fixedly connected to a fixing post 801. A ball bearing is provided inside the fixing post 801. The ball bearing is used to abut the bottom of the sliding plate 9. Both the fixing post 801 and the ball bearing are made of silicone.

[0029] Working principle: Before soaking the rice, the staff first put the rice that meets the working requirements into the filter cloth 5, then remove the sealing cover 4, and put the filter cloth 5 and rice into the rotating tank 2. Then, water is injected into the filter cloth 5. The water passes through the filter cloth 5 and enters the rotating tank 2. The injection is stopped when the water meets the working requirements. At the same time, the staff connects the external pressure control device to the air bag 25.

[0030] When the rice soaking is complete and the drainage process is underway, the external pressure control device reduces the pressure inside the air bladder 25, thereby reducing the friction between the air bladder 25 and the rotating tank 2. Then, the operator controls the telescopic ends of the two electric push rods 8 to move downwards via the control terminal. At this point, the telescopic ends of the two electric push rods 8 no longer press against the sliding plate 9. Under the weight provided by the water, the sliding plate 9 is pressed downwards. During the movement of the sliding plate 9, the fixed rod 17 moves downwards (during the movement of the sliding plate 9, it disengages from the filter cloth 5, and the filter cloth 5 then droops).

[0031] During the movement of the fixed rod 17, the lower first sliding block 18 presses against the corresponding second spring limiting pin 20, causing the second spring limiting pin 20 to move and store force. When the first sliding block 18 moves to be limited by the corresponding second spring limiting pin 20 (the second spring limiting pin 20 is located between the two first sliding blocks 18), the telescopic ends of the two electric push rods 8 have already moved to this position, and at this time the sliding plate 9 has contacted the ball on the fixed column 801. Through the above actions, the mode is switched, so that the device is now in the mode of treating residual moisture in rice.

[0032] After the mode switch is completed, the operator controls the telescopic ends of the two electric push rods 8 to move upward via the control terminal (the distance the telescopic ends of the electric push rods 8 extend is the distance the first spring limiting pin 14 slides from the lower part to the upper part of the inclined groove of the fixed cylinder 11). The telescopic ends of the electric push rods 8 drive the sliding plate 9 to move synchronously. The sliding plate 9 moves upward synchronously via the fixed rod 17, the corresponding second spring limiting pin 20, the fixed shell 19, the connecting ring 16, the connecting frame 15, the connecting cylinder 13 and its auxiliary parts. During the upward movement of the connecting cylinder 13, the first spring limiting pin 14 moves along the fixed cylinder 11. 1. The inclined groove moves from bottom to top. During the movement, guided by the inclined groove of the fixed cylinder 11, the first spring limiting pin 14, the connecting cylinder 13 and its upper parts and the sliding plate 9 rotate on their own during the upward movement (during this process, the connecting cylinder 13 slides relative to the connecting frame 12 and the fixed cylinder 11, the connecting frame 12 rotates relative to the fixed cylinder 11, and the first tension spring is stretched and twisted at this time). During the rotation of the sliding plate 9, the filter cloth 5 is clamped by the squeezing column 24, causing the lower part of the filter cloth 5 to rotate as well (this action simulates the action of clamping the lower part of the plastic bag and twisting it).

[0033] When the telescopic end of the electric push rod 8 extends to contact the upper side of the inclined groove of the first spring limiting pin 14 and the fixed cylinder 11, the first spring limiting pin 14 is pressed by the corresponding pressing pin 21, causing the first spring limiting pin 14 to temporarily disengage from the inclined groove of the fixed cylinder 11 and attract the second sliding block 22. At the same time, the telescopic end of the electric push rod 8 quickly retracts (retracts to the position of receiving the sliding plate 9). Under the action of the first tension spring on the lower side of the connecting cylinder 13, the connecting cylinder 13 drives the parts on it to move rapidly downward. During the movement, the first spring limiting pin 14 drives the second sliding block 22 to move synchronously. During the process, the spring is squeezed (the elastic force of the spring gradually increases during the squeezing process). The above working principle is achieved so that the sliding plate 9 can be squeezed by the squeezing column 24 to hold the filter cloth 5 during the upward movement, and the lower part of the filter cloth 5 will also rotate. However, at this time, the first spring limiting pin 14 is no longer in contact with the inclined groove of the fixed cylinder 11. This makes the downward movement speed of the sliding plate 9 faster than the reset speed of the filter cloth 5, so as to realize the rapid reset of the sliding plate 9 and no longer interfere with the reset action of the filter cloth 5. Through the reset of the filter cloth 5, the rice is driven to rotate in the rotating tank 2, and the residual water in the rice is thrown out, shortening the time for dehydration of the rice.

[0034] When the magnetic force between the first spring limiting pin 14 and the second sliding block 22 is less than the squeezing force provided by the adjacent spring of the second sliding block 22, the spring drives the second sliding block 22 to reset upward, while the first spring limiting pin 14 continues to move downward to reset. Under the action of elasticity, the first spring limiting pin 14 moves back towards the fixed cylinder 11 and gradually moves to contact the inclined groove on the fixed cylinder 11. When the sliding plate 9 moves to contact the inner ball of the fixed column 801 again, the above action can be repeated.

[0035] When it is no longer necessary to remove residual moisture from the rice, the telescopic end of the electric push rod 8 continues to retract. After the sliding plate 9 loses its support, it drives the fixed rod 17 to move downward. During this process, the upper first sliding block 18 first presses the corresponding second spring limit pin 20, causing the second spring limit pin 20 to move and store force. When the upper first sliding block 18 is located below the corresponding second spring limit pin 20, the second spring limit pin 20 resets, and the sliding plate 9 contacts the ball bearing inside the fixed post 801. At this time, the telescopic end of the electric push rod 8 moves upward, and the upper first sliding block 18, under the blocking action of the second spring limit pin 20, undergoes relative displacement with the fixed rod 17 (during this process, the second tension spring is stretched). (Extend), and the two first sliding blocks 18 are in contact. As the sliding plate 9 continues to move upward, it drives the two first sliding blocks 18 to move upward synchronously through the fixed rod 17. The upper first sliding block 18 squeezes the second spring limiting pin 20, causing the second spring limiting pin 20 to move and store force. Thus, the two first sliding blocks 18 move upward synchronously with the fixed rod 17 (when the two first sliding blocks 18 pass the second spring limiting pin 20, the second spring limiting pin 20 returns to its original position). At this time, the processing mode for residual moisture in the rice has been switched to the normal mode. When the sliding plate 9 moves to the position shown in the attached figure, the processing of the rice is completed. At this point, the filter cloth 5 and the rice are taken out.

[0036] Example 3 Based on Example 2, please refer to Figures 1-10 A rice soaking process for a pre-processed rice product production line, characterized by the following specific steps according to the aforementioned rice soaking device for a pre-processed rice product production line: Step 1: Before soaking the rice, put the rice into filter cloth 5, then put filter cloth 5 into rotating tank 2 and add water into filter cloth 5. Step 2: Once the water level reaches the required amount, the rice needs to be soaked for the specified time. Step 3: After the rice has been soaked, open the electric control valve 7 to connect the rotating tank 2 to the outside world through the connecting pipe 6. The telescopic end of the electric push rod 8 drives the sliding plate 9 to rise, so that light impurities are squeezed out. Step 4: After the light impurities have been processed, close the electric control valve 7, drive the rotating tank 2 to rotate 180° to invert the rice, and then drive the rotating tank 2 to rotate 180° in the opposite direction. Step 5: After the rice has finished soaking, the telescopic end of the electric push rod 8 moves down, switching to the mode for processing the residual moisture in the rice. Step 6: During the process of treating the residual moisture in the rice, the telescopic end of the electric push rod 8 drives the sliding plate 9 to move upward. The sliding plate 9 clamps the filter cloth 5 through the squeezing column 24, causing the lower part of the filter cloth 5 to twist as it is lifted upward. Step 7: When the sliding plate 9 moves down rapidly, it disengages from the filter cloth 5, the filter cloth 5 returns to its original position, and the residual water in the rice is shaken out; Step 8: After removing the residual moisture from the rice, remove the rice.

[0037] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
