Description

Technical Field

[0001] This utility model relates to the field of starch processing equipment, specifically to a device for preparing and dispensing water starch on the spot. Background Technology

[0002] Cornstarch, made from starch and water, absorbs water and gelatinizes when heated to 60 degrees Celsius, becoming sticky, smooth, and glossy. Chefs utilize these properties of cornstarch when thickening sauces. Near the end of cooking, the prepared cornstarch mixture is poured over the surface of the dish to increase its viscosity and thickness, maintaining the dish's crispness and tenderness. Thickening also helps to integrate the sauce and the main ingredient, highlighting the main ingredient and giving it a bright appearance. Additionally, the thickened sauce helps retain heat in the dish.

[0003] Before cooking, the chef prepares a cornstarch slurry in a container according to the specified ratio. Over time, the cornstarch slurry will settle. Before the dish is finished cooking, the chef must use a spatula to disperse the cornstarch slurry, and then add it to the dish. The chef relies on experience to measure the cornstarch slurry, and it cannot be precisely measured. When adding it, it should not be spread out over a large area of ​​the dish. After adding it, it must be quickly stir-fried so that the cornstarch slurry can quickly coat the dish. If it is not stirred in time or is added to the surface of the pan without any other ingredients, the cornstarch will stick to the pan.

[0004] To address the aforementioned technical issues, Chinese patent publication CN219000126U, entitled "Intelligent Mixer for Making Sauce in a Stir-Fry Machine," requires adding water and cornstarch to a storage hopper and using ultrasonic vibration to mix the powder and water, achieving uniform mixing through the cavitation effect of sound waves. Its drawbacks are: the ultrasonic effect is weakened in high-viscosity liquids, leading to decreased mixing uniformity. Furthermore, the amount of water and cornstarch needed can only be estimated beforehand; if the actual usage is small, the pre-mixed starch mixture will be wasted; if the actual usage is large, water and cornstarch must be added again for mixing, resulting in limited convenience and adaptability.

[0005] Chinese patent publication CN 112869595A, entitled "Automatic Thickening System, Food Processor, and Automatic Thickening Control Method," describes a system that uses pneumatic drive and a sealed cavity to mix powder and water. A controller regulates the water pump and screw feeding. In operation, a measured amount of water is first injected into the thickening liquid container. Then, an air pump blows air into the powder delivery pipe, transporting the thickening powder to the sealed cavity where it mixes with water to form a thickening liquid. The rising gas in the water causes it to swirl, promoting the blending of the thickening powder and water into a uniform thickening liquid. However, this system has several drawbacks: it requires an air source, which needs air filtration. In a kitchen, this necessitates an additional air source, increasing operating costs. Furthermore, this patent also requires prior estimation of the required usage. Utility Model Content

[0006] The purpose of this invention is to provide a water starch mixing device that can effectively solve the problem that existing water starch mixing equipment requires estimating the usage amount before mixing, and cannot accurately mix according to the usage amount.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] A device for preparing and dispensing starch on demand, comprising:

[0009] A dry starch conveying mechanism is configured to store and quantitatively convey dry starch.

[0010] A liquid delivery mechanism configured to quantitatively deliver water; and,

[0011] The mixing assembly includes a mixing joint connected to the dry starch conveying mechanism and the liquid conveying mechanism. A mixing channel is connected downstream of the mixing joint. The mixing channel is provided with a turbulence generating structure, which is configured to generate turbulence by changing the fluid flow path or velocity distribution, thereby mixing dry starch and water into water starch.

[0012] In the above-mentioned water starch preparation and dispensing device, the inner wall of the mixing channel is provided with a blocking element to form the turbulence generation structure.

[0013] In the aforementioned water starch preparation and addition device, the blocking element is spirally arranged on the inner wall of the mixing channel.

[0014] In the aforementioned water starch mixing and dispensing device, the pitch of the spiral blades gradually decreases along the fluid flow direction to improve mixing uniformity.

[0015] In the above-mentioned water starch preparation and dispensing device, the blocking components are arranged in multiple alternating stages on the inner wall of the mixing channel to form a meandering flow channel.

[0016] In the above-mentioned water starch preparation and addition device, the mixing channel is at least partially spiral-shaped to form the turbulence generation structure; or, the cross-sectional area of ​​the mixing channel alternately shrinks and expands to generate the Venturi effect and form the turbulence generation structure.

[0017] In the above-mentioned water starch on-site mixing and dispensing device, the dry starch conveying mechanism includes a dry starch container, a metering screw and a drive motor. The bottom of the dry starch container is provided with an output channel that connects to the mixing connector. The metering screw extends into the output channel at the bottom of the dry starch container. The drive motor is connected to the metering screw to drive it to rotate.

[0018] In the aforementioned water starch on-site mixing and dispensing device, the dry starch conveying mechanism further includes a first solenoid valve for controlling the on / off state of the output channel.

[0019] In the above-mentioned water starch on-site mixing and dispensing device, the dry starch container is provided with an opening, the dry starch conveying mechanism further includes an end cap that closes the opening of the dry starch container, the drive motor is fixed on the end cap, and the end cap is also provided with a powder adding hole.

[0020] In the aforementioned water starch on-site preparation and dispensing device, the liquid conveying mechanism includes a water pipe connected to a water source, a flow meter for monitoring the water volume in the water pipe, and a second solenoid valve for controlling the on / off state of the water pipe and the water flow rate.

[0021] Compared with the prior art, the advantages of this utility model are:

[0022] By setting up a mixing channel with a turbulence generation structure, the problem of existing water starch mixing equipment requiring estimated usage before mixing, which cannot accurately mix according to the usage, is solved.

[0023] The dry starch conveying mechanism stores and quantitatively delivers dry starch, while the liquid conveying mechanism quantitatively delivers water. These two mechanisms ensure precise delivery of dry starch and water according to a preset ratio during the preparation of starch-water mixtures. In the mixing assembly, a mixing joint connects the dry starch and liquid conveying mechanisms, allowing the dry starch and water to initially converge. The downstream mixing channel is equipped with a turbulence-generating structure, which generates turbulence by altering the fluid flow path or velocity distribution to achieve mixing. The generation of turbulence significantly increases the contact area and mixing intensity between the dry starch and water. Compared to traditional simple stirring and mixing methods, this turbulence-based mixing method achieves better mixing results in a shorter time, enabling on-site preparation and dispensing.

[0024] Because dry starch and water are mixed within the mixing channel via a turbulence-generating structure, this device can prepare starch slurry on demand based on actual usage, avoiding waste or shortages caused by pre-estimating usage. This improves convenience and adaptability, overcoming the shortcomings of existing technologies that require pre-estimating the amount of water and starch to be added, where the actual usage differs from the estimate. The mixing channel of the mixing component is equipped with a turbulence-generating structure, which generates turbulence by changing the fluid flow path or velocity distribution to achieve mixing of dry starch and water. Compared to ultrasonic vibration mixing or pneumatically driven mixing, this method is unaffected by high-viscosity liquids and can ensure uniform mixing of dry starch and water into starch slurry under various conditions, improving the uniformity and stability of the mixing.

[0025] Furthermore, the inner wall of the mixing channel is equipped with baffles to form the turbulence-generating structure. These baffles alter the flow path and velocity distribution of the fluid, causing turbulence between the dry starch and water within the mixing channel. In turbulent conditions, the irregular movement of the fluid increases the collisions, friction, and shearing between the dry starch and water, resulting in more thorough mixing and improved uniformity of the starch mixture. Forming the turbulence-generating structure by using baffles on the inner wall of the mixing channel eliminates the need for complex equipment or special techniques. The baffles can be simple protrusions, grooves, or other shaped structures, making them easy to manufacture and install, thus reducing the design and manufacturing costs of the device. This relatively simple structure, without excessive complex components, makes the internal structure of the mixing channel clearer, facilitating inspection, maintenance, and cleaning during use. If dry starch or other impurities adhere to the baffles or the inner wall of the channel, they are also relatively easy to clean, helping to maintain the normal operation of the device and the stability of the mixing effect.

[0026] Furthermore, the baffle is spirally arranged on the inner wall of the mixing channel. This spiral arrangement guides the fluid along a spiral path, creating not only radial turbulence but also axial spiral flow between the dry starch and water within the mixing tube. This combined flow pattern significantly increases the mixing intensity between the fluids, prolonging the contact time between the dry starch and water within the mixing tube, allowing them to more fully interpenetrate and diffuse, thereby significantly improving the uniformity of the mixture and ensuring that the final product has a fine texture and uniform concentration of starch.

[0027] Furthermore, the pitch of the helical blades gradually decreases along the fluid flow direction to improve mixing uniformity. As the pitch gradually decreases, the flow velocity and direction of the fluid within the mixing channel continuously change. In the initial section with a larger pitch, the fluid has relatively large flow space, enabling rapid initial mixing; while at the end with a smaller pitch, the fluid is further compressed and sheared, deepening the mixing. This process continuously increases the contact area between the dry starch and water, enhancing diffusion and convection, allowing starch granules to be more evenly dispersed in the water. This ensures that the final water-starch solution has a consistent concentration and uniform texture, effectively improving product quality and guaranteeing consistency in taste and appearance in applications such as cooking and food processing.

[0028] Furthermore, multiple obstructions are arranged in a multi-level, staggered pattern on the inner wall of the mixing channel, forming a meandering flow path. This meandering flow path makes the flow path of dry starch and water within the mixing channel complex and tortuous. As the fluid flows through the multi-level, staggered obstructions, it continuously changes its flow direction and velocity, resulting in multiple collisions, splitting, and merging. This significantly increases the contact area and mixing intensity between the dry starch and water, allowing for more thorough and uniform mixing and improving the mixing quality of the starch-water mixture. The multi-level, staggered obstructions can be flexibly adjusted according to different flow rates and the characteristics of the dry starch and water. For larger flow rates, the meandering flow path effectively disperses the fluid, preventing insufficient mixing due to excessive flow velocity. For dry starches of different particle sizes or viscosities, the mixing effect can be optimized by adjusting the number of obstruction levels, the staggering pattern, and the spacing, giving the device strong adaptability and versatility. The meandering flow path extends the residence time of dry starch and water within the mixing channel. This allows the two materials more time to mix, contributing to improved mixing uniformity and stability. Especially for situations where thorough mixing is required to achieve the desired effect, such as preparing high-precision starch, a longer residence time can ensure the consistency of the mixing quality.

[0029] Furthermore, the mixing channel is at least partially spiral-shaped, forming the turbulence-generating structure; or, the cross-sectional area of ​​the mixing channel alternately shrinks and expands, generating a Venturi effect to form the turbulence-generating structure. The spiral-shaped mixing channel causes the fluid to form a spiral flow path, increasing the flow distance and time, generating centrifugal force, and promoting radial and axial movement of dry starch and water, ensuring full contact and mixing, improving the uniformity of water-starch, and guiding the fluid to form a regular spiral flow, avoiding turbulence or local dead zones, maintaining a stable turbulent state, improving the consistency and repeatability of mixing, and ensuring the stable quality of water-starch prepared each time; within a limited space, by increasing the length of the fluid flow path, the channel space is fully utilized, the mixing efficiency is improved, and the device structure is made more compact. The Venturi effect causes the fluid velocity to increase where the cross-sectional area of ​​the channel decreases and decrease where it increases. This rapid change in velocity induces turbulence. This method can efficiently mix dry starch and water under high-speed flow and pressure changes, improving mixing efficiency. Due to the periodic changes in velocity and pressure, the dry starch and water in the fluid are repeatedly stirred and mixed, which can effectively avoid local uneven mixing and thus obtain water starch with high uniformity.

[0030] Furthermore, the dry starch conveying mechanism includes a dry starch container, a metering screw, and a drive motor. The bottom of the dry starch container has an output channel that connects to the mixing connector. The metering screw extends into the output channel at the bottom of the dry starch container. The drive motor is connected to the metering screw to drive its rotation. By controlling the speed and number of rotations of the drive motor, the output amount of dry starch can be precisely controlled. This allows for accurate addition of dry starch according to a preset ratio when preparing starch slurry, ensuring a stable and consistent concentration and quality of starch slurry each time, and avoiding poor cooking results or product quality problems caused by inaccurate dosage of dry starch.

[0031] Furthermore, the dry starch conveying mechanism also includes a first solenoid valve for controlling the opening and closing of the output channel. The first solenoid valve can quickly and accurately control the opening and closing of the output channel. When dry starch needs to be conveyed, the solenoid valve opens, allowing the dry starch to smoothly pass through the output channel into the mixing joint; when dry starch is not needed, the solenoid valve quickly closes, cutting off the conveying path of the dry starch, precisely controlling the start and stop of dry starch conveying, avoiding excessive conveying or continuous leakage of dry starch, and helping to improve the accuracy of water starch preparation. The solenoid valve has an extremely fast response speed, completing the opening and closing actions in a short time. This allows the dry starch conveying mechanism to quickly respond to the system's control commands, adjusting the conveying status of dry starch in a timely manner according to actual production needs, improving the automation level and production efficiency of the entire water starch preparation system. By controlling the opening and closing of the output channel through the first solenoid valve, it is possible to effectively prevent the accidental leakage of dry starch when it is not needed, avoiding waste and environmental pollution caused by dry starch leakage. At the same time, the solenoid valve has high reliability, maintaining a stable working state during long-term operation, reducing abnormal dry starch conveying caused by mechanical failures, and improving the stability and reliability of the entire dry starch conveying mechanism and even the water starch preparation system.

[0032] Furthermore, the dry starch container has an opening, and the dry starch conveying mechanism also includes an end cap that seals the opening of the dry starch container. The drive motor is fixed to the end cap, and the end cap also has a powder-adding hole. The end cap seals the dry starch container, providing stable structural support. The drive motor is fixed to the end cap, ensuring a stable motor position, reducing vibration and displacement during operation, and guaranteeing that the metering screw can rotate accurately and smoothly, thereby achieving stable quantitative conveying of dry starch. Stable motor installation helps extend the service life of the equipment, reduces noise during operation, ensures the stability of the entire device during operation, and improves the reliability of the equipment. The powder-adding hole on the end cap provides a convenient way to add dry starch to the container. Operators can directly add dry starch through the powder-adding hole without disassembling the entire dry starch conveying mechanism, saving time and labor costs. The design of the powder-adding hole also avoids dust flying due to frequent opening of the container during the addition of dry starch, maintaining a clean working environment, while reducing the risk of dry starch becoming damp or contaminated, ensuring the quality and performance of the dry starch.

[0033] Furthermore, the liquid delivery mechanism includes a water pipe connected to a water source, a flow meter that monitors the water volume in the pipe, and a second solenoid valve that controls the opening and closing of the pipe and the water flow rate. The flow meter can monitor the water volume in the pipe in real time, providing data support for precise control. In conjunction with the second solenoid valve, the water flow rate can be accurately controlled according to a preset formula, ensuring precise water delivery each time, thereby guaranteeing a stable starch concentration to meet different cooking needs. The combination of the flow meter and the second solenoid valve facilitates automated control. The entire liquid delivery process can be precisely regulated by an electronic control system, automatically completing water delivery and flow rate adjustment according to a preset program, reducing manual intervention and improving the automation level and consistency of production.

Detailed Implementation

[0038] A device for preparing and dispensing starch on demand, comprising:

[0039] The dry starch conveying mechanism 10 is configured to store and quantitatively convey dry starch.

[0040] Liquid delivery mechanism 20, configured to deliver water in a metering manner; and,

[0041] The mixing assembly 30 includes a mixing joint 31 connected to the dry starch conveying mechanism 10 and the liquid conveying mechanism 20. A mixing channel is connected downstream of the mixing joint 31. The mixing channel is provided with a turbulence generating structure 32. The turbulence generating structure 32 is configured to generate turbulence by changing the fluid flow path or flow velocity distribution, so as to mix dry starch with water to form water starch.

[0042] By setting up a mixing channel with a turbulence generation structure 32, the problem of existing water starch mixing equipment requiring estimation of usage before mixing, and not being able to accurately mix according to usage, is solved.

[0043] The dry starch conveying mechanism 10 is responsible for storing and quantitatively conveying dry starch, while the liquid conveying mechanism 20 quantitatively conveys water. These two mechanisms ensure that dry starch and water are precisely conveyed according to a preset ratio during the preparation of starch-water mixtures. In the mixing assembly 30, the mixing joint 31 connects the dry starch and liquid conveying mechanism 20, allowing the dry starch and water to initially converge. The downstream mixing channel is equipped with a turbulence generating structure 32, which generates turbulence by changing the fluid flow path or velocity distribution to achieve mixing. The generation of turbulence greatly increases the contact area and mixing intensity between the dry starch and water. Compared to traditional simple stirring mixing methods, this turbulence-based mixing method achieves better mixing results in a shorter time.

[0044] Because dry starch and water are mixed within the mixing channel via the turbulence-generating structure 32, this device can prepare starch-water mixtures on demand, avoiding waste or shortages caused by pre-estimating usage. This improves convenience and adaptability, overcoming the shortcomings of existing technologies where water and starch must be added in advance, and the actual usage may differ from the estimate. The mixing channel of the mixing component 30 is equipped with the turbulence-generating structure 32, which generates turbulence by changing the fluid flow path or velocity distribution to achieve mixing of dry starch and water. Compared to ultrasonic vibration mixing or pneumatically driven mixing, this method is unaffected by high-viscosity liquids and can ensure uniform mixing of dry starch and water into starch-water mixtures under various conditions, improving the uniformity and stability of the mixing.

[0045] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0047] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0048] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0049] See Figure 1 , Figure 2 This invention relates to an embodiment of a water starch on-site mixing and dispensing device. The device includes a dry starch conveying mechanism 10, a liquid conveying mechanism 20, and a mixing component 30. The dry starch conveying mechanism 10 is mainly used to store and quantitatively convey dry starch; the liquid conveying mechanism 20 is mainly used to quantitatively convey water; the mixing component 30 includes a mixing connector 31 and a turbulence generating structure 32. The mixing component 30 is used to connect the dry starch conveying mechanism 10, the liquid conveying mechanism 20, and the turbulence generating structure 32. The turbulence generating structure 32 uses the kinetic energy of liquid flow to mix dry starch and water into water starch.

[0050] Traditional thickening requires pre-prepared starch slurry, which settles after standing and necessitates manual stirring. This device, however, achieves instant mixing of dry starch and water through real-time synchronous delivery within the mixing component 30 using liquid kinetic energy. This eliminates the need for storing starch slurry, completely eliminating the risk of sedimentation and ensuring uniform mixing. By adjusting the delivery rate of dry starch and water and strictly adhering to the preset ratio, it avoids the dosage deviations caused by reliance on chef experience in traditional thickening methods. Furthermore, since dry starch and water are simultaneously delivered to the turbulence generator 32 for mixing, they are readily available, eliminating the need for quantity estimation and completely resolving the problems of "insufficient estimation requiring re-preparation" or "excessive waste," thus improving resource utilization. The mixing component 30 is driven by liquid flow kinetic energy, eliminating the need for ultrasonic waves or air pumps, thus reducing additional equipment such as air filtration, lowering operating and maintenance costs, and making it more suitable for kitchen environments.

[0051] Furthermore, for the mixing connector 31, this embodiment adopts a three-way structure, including a first inlet, a second inlet, and an outlet. The first inlet connects to the outlet of the dry starch conveying mechanism 10, the second inlet connects to the outlet of the liquid conveying mechanism 20, and the outlet communicates with the turbulence generating structure 32. The two inlets, respectively connecting to dry starch and liquid, allow the dry starch and water to initially contact and converge before entering the turbulence generating structure 32, and to initially mix during the flow process. Further mixing occurs upon entering the turbulence generating structure 32, which helps improve the uniformity of the mixture. For example, at the instant that dry starch and water simultaneously enter the three-way connector, the impact force of the water flow can disperse some of the aggregated dry starch particles, making them more evenly distributed in the water flow. This lays the foundation for thorough mixing in the subsequent turbulence generating structure 32, thereby ensuring that the final generated water-starch has stable quality and consistent concentration.

[0052] The T-joint structure of the hybrid connector 31, as an independent component, offers significant advantages in equipment maintenance and upgrades. If the hybrid connector 31 malfunctions, it can be disassembled, repaired, or replaced independently without requiring large-scale disassembly of the entire system, reducing maintenance costs and downtime. Furthermore, during equipment upgrades, if a higher-performance hybrid connector 31 needs to be replaced or the connection method adjusted, its relatively independent structure simplifies operation, enhancing the equipment's scalability and adaptability. Besides the T-joint structure, coaxial sleeves, branched pipes, and other structures can also be used.

[0053] For the turbulence generating structure 32, the inner wall of the mixing channel is provided with a baffle 321 to generate turbulence in the fluid. This baffle 321 in the inner wall of the mixing channel can generate turbulence in the fluid. When dry starch and water enter the mixing channel, under the action of turbulence, the fluid's motion becomes complex and disordered. The dry starch particles are more fully dispersed and dispersed in the water, greatly increasing the contact area between the dry starch and water, accelerating the mixing speed, significantly improving the mixing effect, and making the final water-starch more uniform. This effectively avoids problems such as starch agglomeration and sedimentation, ensuring that the water-starch can play a stable and good role in cooking or other applications, improving the quality of the finished product. The mixing channel structure of this structure is relatively simple, without complex moving parts. Compared with mixing equipment with dynamic parts such as stirrers and rotors, its manufacturing process is simpler, reducing manufacturing costs. Moreover, due to the absence of wear from moving parts, it has higher stability and a lower failure rate during long-term use. Once a problem occurs, it is also easier to inspect and repair, reducing equipment maintenance time and costs, and improving equipment efficiency. The aforementioned turbulence-generating structure 32 of the mixing channel will not suffer fatigue damage due to frequent component movement during operation. The internal baffles 321 are fixed to the pipe wall, preventing loosening or detachment and ensuring the stability and continuity of the mixing effect. This stability helps extend the overall service life of the equipment, reduces the frequency of equipment replacement, and provides users with a long-term reliable user experience, while also aligning with the concept of sustainable development. The turbulence-generating structure 32 can also be a vortex tube, a labyrinthine channel, or a corrugated pipe, etc.

[0054] Furthermore, the blocking component 321 is fixed spirally to the inner wall of the mixing channel, forming a spiral blade. This spiral blocking component 321 guides the fluid along the spiral path, causing the dry starch and water to generate not only radial turbulence but also axial spiral flow within the mixing tube. This composite flow pattern significantly increases the mixing intensity between the fluids, prolonging the contact time between the dry starch and water within the mixing tube, allowing them to more fully interpenetrate and diffuse, thereby significantly improving the uniformity of the mixture and ensuring that the final starch solution has a fine texture and uniform concentration. For example, in the process of thickening sauces, this ensures that each use of starch solution has the same consistency and adhesion, improving the quality of the dish.

[0055] The spiral structure makes the fluid flow within the pipe more orderly and efficient. Compared to ordinary straight baffles 321, spiral baffles 321 can more effectively utilize the fluid's kinetic energy and reduce energy loss. During the spiral propulsion process, the fluid is continuously divided and recombined, accelerating the mixing process and achieving good mixing results within a shorter pipe length. This means that mixing efficiency can be improved without increasing equipment size and energy consumption, meeting the needs of rapid production or cooking, such as increasing the yield of starch per unit time in food processing production lines. The special structure of the spiral baffle 321 helps reduce the adhesion and accumulation of dry starch on the inner wall of the mixing pipe. During fluid flow, the spiral flow trajectory generates a certain scouring effect, which can promptly remove starch particles that may adhere to the pipe wall, preventing starch deposition that could lead to pipe blockage or reduced mixing efficiency. This self-cleaning characteristic not only keeps the mixing pipe unobstructed and reduces equipment maintenance frequency but also ensures the stability and continuity of the mixing process, reducing production costs. The spiral baffle 321 can also rectify and stabilize the fluid entering the mixing pipe. When dry starch and water enter the mixing tube from different inlets, the spiral baffle 321 guides them to quickly form a stable spiral flow, preventing uneven mixing or local pressure fluctuations caused by fluid impact and turbulence. This is crucial for applications requiring high fluid stability, such as high-precision food processing, ensuring the stability of the production process and the consistency of product quality.

[0056] Furthermore, the pitch of the spiral-shaped baffle 321 gradually decreases along the flow direction to improve mixing uniformity. As the pitch gradually decreases, the flow velocity and direction of the fluid within the mixing channel continuously change. In the initial section with a larger pitch, the fluid has relatively large flow space, enabling rapid initial mixing; while at the end with a smaller pitch, the fluid is further compressed and sheared, deepening the mixing. This process continuously increases the contact area between the dry starch and water, enhancing diffusion and convection, allowing starch particles to be more evenly dispersed in the water, ensuring consistent water starch concentration and uniform texture. In applications such as cooking and food processing, this effectively improves product quality and guarantees consistency in taste and appearance. In the initial stage of mixing, the concentration difference between dry starch and water is large, and a larger pitch allows the fluid to flow rapidly, initially mixing a large amount of material; as mixing progresses, the concentration difference decreases, and a smaller pitch better handles the remaining insufficiently mixed portion, refining the mixing process. This design dynamically adjusts the mixing intensity according to the mixing process, making the mixing process more efficient and rational, meeting the mixing needs under different ratios and flow rates, and enhancing the versatility and adaptability of the device. Whether for small-scale mixing of starch and water or large-scale industrial production, it can achieve good mixing results. The reduced screw pitch intensifies fluid turbulence, creating more complex flow patterns within the pipe and accelerating the mixing speed. Compared to a design with a constant screw pitch, this gradually varying screw pitch structure completes the mixing process in a shorter time, increasing the output per unit time.

[0057] In addition to the aforementioned spiral-shaped obstruction 321, the turbulence generating structure 32 can also incorporate multiple obstructions 321 arranged in a multi-stage, staggered manner on the inner wall of the mixing channel, forming a meandering flow path. When the fluid flows through the obstruction 321, the flow cross-section suddenly narrows, and the flow velocity accelerates at the leading edge of the obstruction 321. At the trailing edge, a low-pressure zone forms due to cross-sectional expansion, causing the fluid to detach from the wall and generate boundary layer separation, forming a Karman vortex street. Before the vortices generated by the first layer of obstructions 321 dissipate, the fluid enters the second layer of staggered obstruction regions. The new vortices interact with the residual vortices, generating secondary flow and forming a three-dimensional turbulent field. Each stage of obstructions 321 creates a velocity gradient in the fluid. After multi-stage series connection, the total shear rate can reach 3-5 times that of a single stage, significantly reducing the time compared to traditional stirring methods and greatly improving the uniformity of starch dispersion.

[0058] A liquid outlet pipe can also be connected to the outlet of the mixing connector 31. The liquid outlet pipe contains a mixing channel, and part of the liquid outlet pipe is spiral-shaped, forming a turbulence generating structure 32. When the fluid enters the spiral pipe, a high-pressure zone is generated on the outer wall due to centrifugal force, while a low-pressure zone is formed on the inner wall, creating a pair of rotating "water vortices" that continuously tumble, thereby achieving rapid and forceful mixing of starch and water. Alternatively, the cross-sectional area of ​​the mixing channel can alternately shrink and expand, generating a Venturi effect to form the turbulence generating structure 32. Through the three-stage mechanism of kinetic energy accumulation in the contraction section, shear instability in the throat, and flow separation in the expansion section, laminar flow is transformed into high-intensity turbulence. The multi-stage series design can significantly improve the starch-water mixing efficiency. Its core advantage lies in achieving microsecond-level instantaneous mixing without any mechanical moving parts.

[0059] Based on the above embodiments, the dry starch conveying mechanism 10 includes a dry starch container 11, a metering screw 12, and a drive motor 13. The bottom of the dry starch container 11 has an output channel 14 that connects to the mixing connector 31. The metering screw 12 extends partially into the output channel 14 at the bottom of the dry starch container 11. The drive motor 13 is connected to the metering screw 12 to drive its rotation, thereby quantitatively conveying dry starch. The metering screw 12 extends into the output channel 14 at the bottom of the dry starch container 11, and the drive motor 13 drives its rotation to achieve quantitative conveying of dry starch. By controlling the speed and number of rotations of the drive motor 13, the output amount of dry starch can be precisely controlled. This allows for accurate addition of dry starch according to a preset ratio when preparing starch slurry, ensuring stable concentration and consistent quality of the prepared starch slurry each time, avoiding poor cooking results or product quality problems caused by inaccurate dry starch dosage. In large-scale food processing, precise quantitative conveying ensures the standardization of product taste and quality. The bottom of the dry starch container 11 has an output channel 14 that directly connects to the mixing connector 31, reducing the complexity and length of pipe connections and making the dry starch conveying path shorter and more direct. This compact structural design saves space and facilitates equipment integration and installation, making it particularly suitable for small kitchen equipment with limited space or production scenarios with high requirements for equipment compactness. At the same time, the simple structure also reduces the risk of material residue and facilitates equipment cleaning and maintenance. The combined operation of the metering screw 12 and the drive motor 13 is relatively stable. The mechanical structure of the metering screw 12 ensures the continuity and stability of dry starch conveying and is not easily affected by external factors.

[0060] Furthermore, the dry starch conveying mechanism 10 also includes a first solenoid valve 15 that controls the opening and closing of the output channel 14. The first solenoid valve 15 can precisely control the opening and closing of the dry starch output channel 14. When dry starch needs to be conveyed, the solenoid valve opens quickly, ensuring that the dry starch pushed by the metering screw 12 smoothly enters the mixing joint 31; when the preset dry starch conveying amount is reached, the solenoid valve closes in time to prevent excess dry starch from entering, ensuring the accurate mixing ratio of dry starch and water. This precise control improves the accuracy of the water-starch ratio and ensures the quality stability of the final product, for example, ensuring consistent thickening effects for each dish during cooking. After the dry starch conveying is completed, the solenoid valve closes the output channel 14, effectively preventing further leakage of dry starch from the dry starch container 11 and avoiding residue and accumulation of dry starch in the pipes. Without the solenoid valve, residual dry starch may become damp and clump together, clogging the pipes and affecting the normal operation of the equipment. The solenoid valve reduces this risk, ensuring continuous and stable operation of the equipment and reducing equipment failures and maintenance costs caused by blockages. By precisely controlling the conveying process of dry starch, the first solenoid valve 15 avoids additional damage to the equipment caused by over-conveying or material residue. In emergencies, the solenoid valve can quickly cut off the dry starch conveying channel, providing safety protection. For example, when the equipment malfunctions or malfunctions, the solenoid valve can be immediately closed to prevent continuous conveying of dry starch, avoiding safety issues caused by uncontrolled material flow, such as the risk of explosion due to starch dust accumulation. This provides strong protection for the safety of equipment operation and operators.

[0061] In addition, in this embodiment, the dry starch container 11 of the dry starch conveying mechanism 10 has an opening at the top, and an end cap 16 is provided at the top of the dry starch container 11 to close the opening. The drive motor 13 is fixed on the end cap 16, and a powder filling hole 17 is provided on the end cap 16. The powder filling hole 17 can also be covered to ensure the airtightness of the dry starch container 11. The end cap 16 closes the dry starch container 11, providing stable structural support for the dry starch container 11. The drive motor 13 is fixed on the end cap 16, making the motor position stable, reducing vibration and displacement during motor operation, and ensuring that the metering screw 12 can rotate accurately and smoothly, thereby achieving stable quantitative conveying of dry starch. Stable motor installation helps to extend the service life of the equipment, reduce the noise during equipment operation, ensure the stability of the entire device during operation, and improve the reliability of the equipment. In scenarios such as food processing where the stability requirements of the equipment are high, stable dry starch conveying is a key factor in ensuring the consistency of product quality. The powder filling hole 17 on the end cap 16 provides a convenient way to add dry starch to the dry starch container 11. Operators can replenish dry starch directly through the powder filling hole 17 without disassembling the entire dry starch conveying mechanism 10, saving time and labor costs. The design of the powder filling hole 17 also avoids dust flying due to frequent opening of the container during the addition of dry starch, maintaining a clean working environment, while reducing the risk of dry starch getting damp and contaminated, ensuring the quality and performance of the dry starch. In continuous production processes in commercial kitchens or food factories, quick and convenient replenishment of dry starch can improve production efficiency and reduce downtime. The sealed end cap 16 effectively prevents the dry starch in the dry starch container 11 from leaking, getting damp, and becoming contaminated. Dry starch maintains good performance when stored in a dry environment, and the sealing effect of the end cap 16 can prevent external moisture, dust, and impurities from entering the container, ensuring the stability of the dry starch quality. For some special starches with high requirements for storage conditions, the sealing protection of the end cap 16 is particularly important, preventing starch deterioration from affecting the final preparation and use of water-based starch, reducing material loss and production costs. The presence of the end cap 16 makes the maintenance and repair of the dry starch conveying mechanism 10 more convenient. Since the drive motor 13 is fixed to the end cover 16, when the motor or other related components malfunction, inspection and repair can be carried out directly by disassembling the end cover 16, without the need for complex disassembly of the entire dry starch container 11. This simplifies the maintenance process and reduces maintenance difficulty and cost. In addition, the connection between the end cover 16 and the dry starch container 11 is usually simple, facilitating quick disassembly and installation, improving equipment maintenance efficiency, reducing equipment downtime, and ensuring production continuity.

[0062] Based on the above embodiments, the liquid conveying mechanism 20 includes a water pipe connected to a water source, a flow meter 21 for detecting the water volume in the pipe, and a second solenoid valve 22 for controlling the opening and closing of the pipe and the water flow rate. The flow meter 21 monitors the water volume in real time and adjusts the water flow rate through the second solenoid valve 22 to achieve synchronous mixing with the dry starch. The water pipe equipped with the second solenoid valve 22 can be directly connected to an external water source. The pipe can be filled with tap water or supplied with water from a water tank at the appropriate mixing temperature, or other liquids can be connected to it. Through the monitoring of the flow meter 21 and the control of the second solenoid valve 22, the concentration and quality of the mixed starch are ensured to be stable each time, avoiding poor cooking results or product quality problems caused by improper mixing. In cooking, precise mixing ensures stable taste, color, and texture of the dish; in the food processing industry, it enables standardized production, improving product quality and market competitiveness.

[0063] This on-site mixing and dispensing device for water starch boasts significant technological advantages. Its biggest highlight is that mixing can be completed solely through water flow, eliminating the need for additional power equipment such as air sources or ultrasonic vibrators. Furthermore, pre-mixing is unnecessary; simply opening the dry starch conveying mechanism 10 and the liquid conveying mechanism 20 yields the prepared water starch. In the dry starch conveying stage, the device consists of a dry starch container, a metering screw 12, a drive motor 13, and a first solenoid valve 15. The bottom of the dry starch container has an output channel 14 that connects to the mixing connector 31. Part of the metering screw 12 extends through this channel and is driven by the drive motor 13 to precisely control the amount of dry starch conveyed. The first solenoid valve 15 enables rapid control of the opening and closing of the output channel 14. On the liquid conveying mechanism 20 side, a water pipe is connected to a water source, and a flow meter 21 and a second solenoid valve 22 are installed on the pipe. The former monitors the water volume in the pipe in real time, while the latter flexibly controls the opening and closing of the pipe and the water flow rate. When water flows through the liquid conveying mechanism 20 into the mixing component 30, it propels the dry starch flow using its own power, achieving initial mixing. In the mixing channel, a unique design further enhances the mixing effect. The mixing channel is at least partially spiral-shaped, or generates a Venturi effect through alternating contractions and expansions in cross-sectional area, while the inner wall of the channel is equipped with multi-level staggered baffles 321, forming a meandering flow path. These designs generate strong turbulence in the fluid, allowing the dry starch and water to fully contact and mix evenly. This mixing method, relying solely on the flow force of water, brings many advantages. First, it reduces the complexity and operating cost of the equipment, eliminating the need for additional air sources or ultrasonic vibrators, thus saving on equipment purchase costs and subsequent maintenance costs. Second, it improves the stability and reliability of the system, reducing operational problems caused by additional equipment failures. In addition, the system structure is more compact, saving installation space in the kitchen and perfectly meeting the actual needs of kitchen use. From raw material delivery to mixing and molding, every step of the entire system works closely together, significantly improving the efficiency and convenience of cooking while enhancing the quality of the water-starch preparation.

[0064] Based on the above embodiments, a synchronization controller can be added. The synchronization controller is configured to synchronously start the dry starch conveying mechanism 10 and the liquid conveying mechanism 20, and during the conveying process, adjust the conveying rate of the dry starch conveying mechanism 10 and the flow rate of the liquid conveying mechanism 20 in real time according to the preset ratio of dry starch to water. This ensures that the mixing ratio of dry starch to water is adapted to the mixing efficiency of the turbulence generating structure 32 until the preset ratio is achieved. The synchronization controller works in conjunction with the dry starch conveying mechanism 10 and the liquid conveying mechanism 20, adjusting the dry starch conveying rate and water flow rate in real time according to the preset ratio to ensure accurate mixing. The flow meter 21 monitors the water volume, and the metering screw 12 controls the amount of dry starch. The error can be controlled within a very small range, ensuring consistent water-starch concentration in each batch, meeting the stringent requirements for mixing accuracy in cooking and industrial production, and improving product quality stability. The synchronization controller achieves automated control; operators only need to set parameters, and the equipment can automatically complete the conveying, mixing, and spraying process of dry starch and water, reducing manual intervention, lowering labor intensity, improving work efficiency, and avoiding errors caused by human factors.
