Description

Technical Field

[0001] The invention relates to the technical field of rice noodle machines, in particular to dry and wet rice slurry stirring, extruding and molding assembly equipment for rice noodle and rice flour machines. Background Art

[0002] Rice noodle machine is a kind of mechanical equipment specially used for producing rice noodles. It processes rice or other grain raw materials into wet powder, and then makes it into rice noodle products of different shapes and specifications through a process. Rice noodle machine is widely used in food processing industry.

[0003] The existing Chinese patent with reference announcement number CN114190516B discloses a wet rice noodle production device, including an extruder, a steamer, two parallel first side plates, two parallel third side plates and two parallel second side plates, one side of the extruder is fixedly connected with two symmetrically arranged extrusion tubes, one side of the extrusion tube is provided with a plurality of extrusion holes, a plurality of heating tubes are arranged inside the steamer, and a third conveyor belt is arranged inside the steamer. The present invention has a simple structure, and the rice noodles are cooled by a cooling component, and the angles of multiple fans can be adjusted simultaneously by an adjustment component. The operation is simple and fast, and the angles of multiple fans can be ensured to be consistent. The rice noodles are bent by a bending component to avoid manual omission of folding, while reducing costs. The cooperation of a clamping component and a stretching component can realize the function of automatic bagging, greatly improving work efficiency.

[0004] Although the patented structure has the effect of wet rice noodle production, it does not have the function of assisting the reflux stirring of rice slurry. When the pressure change of the auger pitch cannot support the full stirring of the rice slurry, the particles inside the rice slurry may not be fully stirred, thereby obtaining granular rice slurry. When the rice slurry is formed into rice noodles, the particles will increase the probability of rice noodles breaking. Due to the insufficient mixing of the rice slurry, the possibility of uneven stress fracture or unripened internal particles after forming is greatly increased, so manual inspection is required, and then the granular rice slurry is poured into the auger again for secondary stirring, which increases the process and reduces the work efficiency. In addition, the structure adopts an open transmission structure. During the material transportation process, there may be a probability that debris falls onto the surface of the conveyor belt, increasing the probability of food safety risks. For this reason, the inventors have proposed a dry and wet rice slurry stirring and extruding molding assembly equipment for rice noodle and rice flour machines to solve the above-mentioned technical problems. Summary of the invention

[0009] The surface of the material distribution plate is provided with connecting holes for assisting the installation of the material distribution plate and the twist rod.

[0010] Furthermore, the distance between the macro-pitch twist pattern and the variable-pitch twist pattern is gradually reduced in a spiral manner. One end of the twist rod is connected to a rotating rod for assisting the twist rod in rotation. One end of the rotating rod is abutted against the twist rod through a rotating shaft. A support platform is installed between the twist rod and the rotating shaft. A support plate is provided in the middle of the support platform.

[0011] Furthermore, a chassis for connecting to an external driving wheel is installed at one end of the rotating rod, and the chassis and the rotating rod are coaxially arranged. A stirring block for increasing the contact area is installed on the surface of the distribution plate. The stirring block structure is symmetrically installed on the surface of the distribution plate, and the stirring block is a rectangular protruding structure.

[0012] Furthermore, the stirring structure includes a hopper, a driving motor, a stirring wheel and a stirring rod, wherein the stirring wheel is installed on the surface of the hopper, the stirring rod is located inside the hopper and abuts against one end of the stirring wheel, and the driving motor is connected to the stirring wheel through a stirring belt; a feeding structure is installed at the bottom of the hopper, the feeding structure includes a feeding rack and a feeding rod installed inside the feeding rack, the feeding rod is a spiral structure, the inside of the feeding rack is respectively connected with the inside of the hopper and the aging structure, and a plurality of stirring plates are installed on the surface of the stirring rod;

[0013] The stirring rod and the stirring plate increase the contact area with the rice slurry, making the distribution of the rice slurry in the hopper more even and improving the mixing effect. The stirring plate generates stronger shear force during rotation, which helps to break up the agglomerated rice slurry and ensure more complete mixing. The feeding rod with a spiral structure can effectively transport the rice slurry from the bottom of the hopper to the maturation structure, avoiding accumulation or blockage of the rice slurry. The spiral structure adopts the above-mentioned micro-pitch twist pattern and variable-pitch twist pattern structure, ensuring that the rice slurry can continuously and stably enter the subsequent maturation process, thereby improving production efficiency.

[0014] Furthermore, the ripening structure includes a ripening frame and a base, the base is installed at one end of the ripening frame, a stirring screw for assisting the stirring and ripening of the rice slurry is arranged inside the ripening frame, a feeding funnel and a discharging pipe are respectively installed on the surface of the ripening frame, the feeding funnel and the discharging pipe are both connected with the inside of the ripening frame, one end of the discharging pipe is abutted with one end of the feeding pipeline, one end of the stirring screw extends beyond the outside of the ripening frame, and is a toothed rotating wheel, the surface of the rotating wheel is connected with a driving belt, one end of the driving belt is connected with a rotating wheel, and one end of the rotating wheel is installed at one end of the twisted rod;

[0015] The stirring screw in the ripening rack rotates continuously to ensure that the rice slurry can be evenly heated during the ripening process, avoiding local overheating or undercooking, and making the rice slurry constantly turned and mixed during the ripening process, which promotes the gelatinization of starch and the denaturation of protein, improves the ripening effect, and effectively transports the rice slurry from the inside of the feed funnel and the hopper to the discharge pipe, avoiding material accumulation or blockage, and ensuring the continuous and stable flow of materials. In addition, this process can be installed with a frequency converter for speed regulation, and the speed of the stirring screw is adjusted by frequency conversion slow twisting or fast twisting to accurately control the residence time of the rice slurry in the ripening rack to ensure the best ripening effect.

[0016] Furthermore, a discharging head is installed at one end of the shell, and a forming screen for assisting the discharging of rice slurry is installed inside the discharging head. A plurality of holes are opened on the surface of the forming screen, and the discharging head is connected with the inside of the shell; the holes on the forming screen can ensure that the rice slurry is evenly extruded into a predetermined shape and size during the discharging process, thereby improving the forming accuracy of the product, and by controlling the size and distribution of the holes, it can be ensured that the diameter and length of each rice noodle or rice product are consistent, thereby improving the consistency of product quality, and when the rice slurry is extruded into rice noodles, the rice noodles can be cooled by blowing air with a fan, which plays the role of cooling and blowing away the rice noodles, avoiding the clumping structure during molding, and also reducing the viscosity of the rice noodles by cooling.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The micro-pitch twist pattern structure is adopted to stir at a uniform speed under the state of micro pitch, so that the rice slurry is fully stirred. By adding variable pitch twist patterns, the instantaneous pressure formed by the reduced pitch after the rice slurry is stirred at a uniform speed increases the pressure resistance of the rice slurry, thereby further reducing the particles inside the rice slurry. The structure of uniform stirring followed by variable pitch stirring essentially constitutes a pressure stirring method after isobaric stirring;

[0019] 2. The rice slurry enters the decompression chamber and the pressure holding chamber in turn through the feeding chamber, and slows down the fluidity of the rice slurry in the decompression chamber, which has a buffering effect. Under the push of pressure, the rice slurry enters the pressure holding chamber through the flow channel, and then enters the discharge groove inside the pressure holding chamber, and is discharged through a hole-shaped opening on the top of the discharge groove, thereby entering the stirring range of the micro-pitch twisted pattern and the variable-pitch twisted pattern again, completing the reflux effect. The multiple stirrings formed by the reflux make the rice slurry more delicate and soft, improve the product quality, and reduce the steps of re-pouring the rice slurry for stirring, thereby improving the work efficiency.

[0020] 3. The rice slurry is stirred multiple times by the cooperation of the stirring structure and the ripening structure. For viscous rice slurry such as dry slurry with different stirring degrees or wet slurry that needs to be evenly stirred and mixed, the processing effect can be improved to achieve the effect of not picking slurry. The stirring structure and the ripening structure both adopt a sealing structure during the stirring process to effectively avoid the situation where the rice noodles turn black due to oil leakage. The heating and ripening method is adopted to play a pressure-keeping and preheating effect, while maintaining the degree of temperature change, and maintaining the maturity of the rice slurry to the maximum extent, so as to achieve the effect of forming the product;

[0021] 4. The performance feature of the present invention is that the rice noodles adopt an automated production and control system, which realizes the standardization and continuity of the production process, avoids the influence of human factors, thereby improving the stability and reliability of the output. Through parameter setting, real-time adjustment can be made according to production needs and changes, ensuring the consistency of product taste and quality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0046] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0047] For this example, please refer to Figure 1-Figure 23 The invention discloses a rice noodle and rice flour machine for mixing and extruding dry and wet rice slurry, comprising a frame 24, a mixing structure, a cooking structure and a variable pitch auger structure, wherein the mixing structure, the cooking structure and the variable pitch auger structure are all mounted on the surface of the frame 24, one end of the mixing structure is in contact with the cooking structure and they are interconnected, the variable pitch auger structure comprises a twist rod 1, a micro twist pattern 2 and a variable pitch twist pattern 3, the micro twist pattern 2 and the variable pitch twist pattern 3 are all mounted on the surface of the twist rod 1 and are in an external thread structure, one end of the twist rod 1 is a mounting platform 4, a material distribution plate 5 is mounted on the surface of the mounting platform 4, and the interior of the twist rod 1 is respectively provided with There are a decompression chamber 6 and a pressure-maintaining chamber 7. The interior of the mounting platform 4 is a mounting groove 8 and a feeding chamber 9. The mounting groove 8 is connected with the feeding chamber 9, and the feeding chamber 9 is connected with the decompression chamber 6. A partition 10 is provided between the decompression chamber 6 and the pressure-maintaining chamber 7. A flow channel 11 is provided in the middle of the partition 10. The flow channel 11 is used to make the decompression chamber 6 and the pressure-maintaining chamber 7 communicate with each other. A discharge groove 12 is provided inside the pressure-maintaining chamber 7. A hole-shaped opening is provided at the top of the discharge groove 12. The hole-shaped opening is connected with the discharge groove 12 and passes through the surface of the twist rod 1. A shell 25 is installed on the outside of the twist rod 1. The aging structure abuts against one end of the shell 25 through a feeding pipe 26.

[0048] The structure of the micro pitch twisted pattern 2 is adopted to stir the rice slurry at a uniform speed under the state of micro pitch adjustment, so that the rice slurry is fully stirred. By adding the variable pitch twisted pattern 3, the instantaneous pressure formed by the reduced pitch after the rice slurry is stirred at a uniform speed increases the compressibility of the rice slurry, thereby further reducing the particles inside the rice slurry. The structure of uniform stirring followed by variable pitch stirring essentially constitutes a pressure stirring method after isobaric stirring.

[0049] The discharged rice slurry enters the decompression chamber 6 and the pressure holding chamber 7 in turn through the feed chamber 9, which slows down the fluidity of the rice slurry in the decompression chamber 6 and has a buffering effect. Under the push of pressure, the rice slurry enters the pressure holding chamber 7 through the flow channel 11, and then enters the discharge groove 12 inside the pressure holding chamber 7, and is discharged through a hole-shaped opening on the top of the discharge groove 12, thereby entering the stirring range of the micro-pitch twisted pattern 2 and the variable-pitch twisted pattern 3 again, completing the reflux effect. The multiple stirrings formed by reflux make the rice slurry more delicate and soft, improve the product quality, and reduce the step of re-pouring the rice slurry for stirring, thereby improving work efficiency.

[0050] The feed chamber 9, the decompression chamber 6, the flow channel 11, the pressure-maintaining chamber 7, the discharge trough 12 and a hole-shaped opening on the top of the trough 12 constitute a reflux structure for assisting the reflux of wet slurry; the structure is adopted to optimize the flow of wet slurry, and by setting the reflux structure, it is ensured that the flow of wet slurry between the various chambers is more stable, and turbulence and pressure fluctuations are reduced, thereby improving the stability of the entire system, helping the wet slurry to be more evenly distributed in the entire system, avoiding the problem of excessively high or low local concentrations, and at the same time shortening the processing time of each batch and improving production efficiency; in addition, through an effective reflux mechanism, the wet slurry can be utilized to the maximum extent, and the loss and waste of rice slurry can be reduced;

[0051] A discharge trough 13 is provided on the surface of the distribution plate 5. The discharge trough 13 is a concave structure and is arranged in a ring on the surface of the distribution plate 5. The distance between two adjacent discharge troughs 13 is equidistant. A feed hole 14 is provided on the surface of the distribution plate 5 to assist the reflux of wet slurry. The feed hole 14 is connected with the feed cavity 9. When the rice slurry passes through the area between the variable pitch twist pattern 3 and the distribution plate 5, the circular shape of the distribution plate 5 is avoided to hinder the movement of the rice slurry. The discharge trough 13 is opened on the surface of the distribution plate 5 to guide the discharge of the rice slurry, thereby reducing the pressure and avoiding splashing and damage to the distribution plate 5 caused by the rice slurry impacting the distribution plate 5. The feed hole 14 assists the reflux of the rice slurry. The rice slurry enters the interior of the decompression cavity 6 and the pressure maintaining cavity 7 through the feed hole 14 to prepare for the reflux of the wet slurry.

[0052] The surface of the material distribution plate 5 is provided with a connection hole 15 for assisting the installation of the material distribution plate 5 and the twist rod 1. A connection block 16 is installed on the surface of the connection hole 15. The connection block 16 and the material distribution plate 5 are detachable structures. The material distribution plate 5 and the twist rod 1 are detachable structures. A support ring 22 is installed between the connection block 16 and the connection hole 15.

[0053] The detachable structure makes the installation and disassembly between the material distribution plate 5 and the twisted rod 1 more convenient, reducing the maintenance and replacement time, and the combined design of the material distribution plate 5, the connecting block 16 and the support ring 22 allows the configuration to be flexibly adjusted according to different application scenarios, thereby improving the adaptability and versatility of the equipment. In addition, the presence of the support ring 22 enhances the contact area between the connecting hole 15 and the connecting block 16, provides additional support force, ensures the stability of the connection, disperses the force applied to the connecting hole 15, avoids damage caused by excessive local force, and prolongs the service life of the components;

[0054] The distance between the macro-pitch twist pattern 2 and the variable-pitch twist pattern 3 is gradually reduced by a spiral descending method; the spiral descending design makes the transition of the rice slurry from the macro-pitch twist pattern 2 to the variable-pitch twist pattern 3 smoother, reduces the impact and uneven distribution of the rice slurry during the stirring process, thereby better controlling the flow speed and direction of the rice slurry, ensuring that it is evenly dispersed throughout the stirring process, and improving the processing efficiency. In addition, the spiral descending design helps to more fully mix the rice slurry between different pitches, and can improve the processing effect for sticky rice slurry such as dry slurry with different stirring degrees or wet slurry that needs to be evenly stirred and mixed. By gradually reducing the pitch, the rice slurry is more easily pushed to the end, reducing the possibility of residue on the surface or in the cavity of the twisted rod 1, and reducing the difficulty of cleaning.

[0055] One end of the twist rod 1 is connected to a rotating rod 17 for assisting the twist rod 1 to rotate. One end of the rotating rod 17 is connected to the twist rod 1 through a rotating shaft 18. A support platform 19 is installed between the twist rod 1 and the rotating shaft 18. A support plate 20 is provided in the middle of the support platform 19. The rotating rod 17, the rotating shaft 18, the support platform 19 and the support plate 20 are all coaxially arranged with the twist rod 1. The coaxial arrangement ensures that the components maintain a consistent center line during the rotation process, reduces vibration and unstable movement caused by eccentricity, makes the force transmission more uniform, avoids damage caused by excessive local force, and enhances the overall mechanical properties. The support platform 19 and the support plate 20 provide support. The connection stability between the twist rod 1 and the rotating rod 17 is enhanced, and the shaking during operation is reduced; one end of the rotating rod 17 is installed with a chassis 21 for connecting the external drive wheel, and the chassis 21 and the rotating rod 17 are coaxially arranged. The coaxial arrangement between the chassis 21 and the rotating rod 17 improves the transmission efficiency, mechanical stability and performance. When the external drive wheel rotates, the force generated instantly is offset by the chassis 21, so that the force generated when the chassis 21 rotates is less than the force of the drive wheel, and the rotating rod 17 is then driven by the slowed down force to rotate, which reduces the risk of wear and failure, and reduces the maintenance cost in long-term operation.

[0056] The surface of the distribution plate 5 is installed with a stirring block 23 for increasing the contact area. The stirring block 23 is symmetrically installed on the surface of the distribution plate 5, and the stirring block 23 is a rectangular protrusion structure; the rectangular protrusion structure increases the contact area between the stirring block 23 and the rice slurry, so that the rice slurry is more evenly distributed during the stirring process, and the mixing effect is improved. The symmetrically installed stirring block 23 can generate shear force during the rotation process, which helps to break up the agglomerated rice slurry and ensure more sufficient mixing. The use of the rectangular protrusion structure effectively guides the material flow path, avoids the accumulation of powder including the rice slurry, and promotes the uniform dispersion of the rice slurry.

[0057] The stirring structure includes a hopper 27, a driving motor 28, a stirring wheel 29 and a stirring rod 30. The stirring wheel 29 is installed on the surface of the hopper 27. The stirring rod 30 is located inside the hopper 27 and abuts against one end of the stirring wheel 29. The driving motor 28 is connected to the stirring wheel 29 through a stirring belt 31. A feeding structure is installed at the bottom of the hopper 27. The feeding structure includes a feeding rack 32 and a feeding rod 33 installed inside the feeding rack 32. The feeding rod 33 is a spiral structure. The inside of the feeding rack 32 is respectively connected with the inside of the hopper 27 and the ripening structure. A plurality of stirring plates 34 are installed on the surface of the stirring rod 30.

[0058] The stirring rod 30 and the stirring plate 34 increase the contact area with the rice slurry, making the distribution of the rice slurry in the hopper 27 more uniform and improving the mixing effect. The stirring plate 34 generates stronger shear force during rotation, which helps to break up the agglomerated rice slurry and ensure more sufficient mixing. The feeding rod 33 with a spiral structure can effectively transport the rice slurry from the bottom of the hopper 27 to the maturation structure, avoiding the accumulation or blockage of the rice slurry. The spiral structure adopts the above-mentioned macro-pitch twisted pattern 2 and variable-pitch twisted pattern 3 structure, ensuring that the rice slurry can continuously and stably enter the subsequent maturation process, thereby improving production efficiency.

[0059] The ripening structure includes a ripening frame 35 and a base 36, the base 36 is installed at one end of the ripening frame 35, the ripening frame 35 is provided with a stirring screw 37 for assisting the stirring and ripening of the rice slurry, the surface of the ripening frame 35 is respectively installed with a feeding funnel 38 and a discharging pipe 39, the feeding funnel 38 and the discharging pipe 39 are both connected with the inside of the ripening frame 35, one end of the discharging pipe 39 abuts against one end of the feeding pipeline 26, one end of the stirring screw 37 extends beyond the outside of the ripening frame 35, and is a toothed rotating wheel 40, the surface of the rotating wheel 40 is connected with a driving belt 41, one end of the driving belt 41 is connected with a rotating wheel 42, one end of the rotating wheel 42 is installed at one end of the twisted rod 1, the spiral structure of the stirring screw 37 adopts the above-mentioned micro-pitch twisted pattern 2 and variable pitch twisted pattern 3 structure, which ensures that the rice slurry can continuously and stably enter the subsequent feeding and extrusion molding process, thereby improving the production efficiency;

[0060] The stirring screw 37 in the ripening rack 35 rotates continuously to ensure that the rice slurry can be evenly heated during the ripening process, avoiding local overheating or undercooking, and making the rice slurry constantly turned and mixed during the ripening process, promoting the gelatinization of starch and the denaturation of protein, improving the ripening effect, and effectively transporting the rice slurry from the inside of the feed funnel 38 and the hopper 27 to the discharge pipe 39, avoiding material accumulation or blockage, and ensuring the continuous and stable flow of the material. In addition, this process can be equipped with a frequency converter for speed regulation, using a variable frequency slow twist or fast twist method. The rotation speed of the stirring screw 37 is adjusted to accurately control the residence time of the rice slurry in the ripening rack 35 to ensure the best ripening effect. In addition, a soft start can be added to save power or protect the inverter from overload. Two schemes are used for ripening standby. When a single condition cannot meet the ripening process, the other scheme can be started to reduce the risk of process interruption. In addition, a heating structure can be installed on the outer side or inside of the ripening rack 35. The heating structure includes an electric heating wire or an electric heating block to assist the operation of the ripening process by heat preservation and heating.

[0061] A discharging head 43 is installed at one end of the shell 25, and a forming screen 44 for assisting the discharging of rice slurry is installed inside the discharging head 43. A plurality of holes are opened on the surface of the forming screen 44, and the discharging head 43 is connected with the inside of the shell 25; the holes on the forming screen 44 can ensure that the rice slurry is evenly extruded into a predetermined shape and size during the discharging process, thereby improving the forming accuracy of the product, and by controlling the size and distribution of the holes, it can be ensured that the diameter and length of each rice noodle or rice product are consistent, thereby improving the consistency of product quality, and when the rice slurry is extruded into rice noodles, the rice noodles can be cooled by blowing air with a fan, which plays the role of cooling and blowing away the rice noodles, avoiding the clumping structure during molding, and reducing the viscosity of the rice noodles by cooling.

[0062] The key points of the design of the present invention are: the structure of the micro-pitch twisted pattern 2 is adopted to stir at a uniform speed under the state of micro pitch, so that the rice slurry is fully stirred, and the variable pitch twisted pattern 3 is added to increase the instantaneous pressure formed by the reduced pitch after the rice slurry is stirred at a uniform speed, thereby increasing the compressibility of the rice slurry, thereby further reducing the particles inside the rice slurry. The structure of uniform stirring followed by variable pitch stirring essentially constitutes a pressure stirring method after isobaric stirring;

[0063] The rice slurry enters the decompression chamber 6 and the pressure-holding chamber 7 in sequence through the feed chamber 9, and plays a role in slowing down the fluidity of the rice slurry in the decompression chamber 6, and plays a buffering effect. Under the push of pressure, the rice slurry enters the pressure-holding chamber 7 through the flow channel 11, and then enters the discharge groove 12 inside the pressure-holding chamber 7, and is discharged through a hole-shaped opening at the top of the discharge groove 12, so as to enter the stirring range of the micro-pitch twisted pattern 2 and the variable-pitch twisted pattern 3 again, and complete the reflux effect. The multiple stirrings formed by the reflux make the rice slurry more delicate and soft, improve the product quality, and reduce the steps of re-pouring the rice slurry for stirring, thereby improving the work efficiency.

[0064] In addition, the rice slurry is stirred multiple times by cooperating with the stirring structure and the maturation structure. The processing effect can be improved for sticky rice slurries such as dry slurry with different stirring degrees or wet slurry that needs to be evenly stirred and mixed, so as to achieve the effect of not being picky about slurry. A sealing structure is adopted during the stirring process of the stirring structure and the maturation structure to effectively avoid the situation where oil leakage causes the rice noodles to turn black. The heating and maturation method is adopted to maintain the pressure and preheating effect, while maintaining the degree of temperature change, and maintaining the maturity of the rice slurry to the maximum extent, so as to achieve the effect of forming the product.

[0065] The action process of the present invention is as follows: rice flour is poured into the interior of the hopper 27, and then the driving motor 28 is started. The driving force generated by the driving motor 28 causes the stirring wheel 29, the stirring rod 30 and the stirring plate 34 to stir the rice slurry, and then the rice slurry enters the interior of the feeding rack 32, and the rice slurry is squeezed into the interior of the ripening rack 35 by the feeding rod 33, and the rice slurry is pressurized by the stirring screw 37 so that the rice slurry passes through the discharge pipe 39 and the feeding pipeline 26 and enters the interior of the shell 25, and then the rice slurry is stirred and squeezed by the variable pitch auger inside the shell 25, and the rice slurry is formed through the discharge head 43 and the forming screen 44 by the extrusion force, thereby completing the manufacturing process of rice noodles.

For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as the protection scope of the present invention.
