Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a sauce mixing mechanism, a thickening device, and a stir-fry machine. Background Technology

[0002] This invention relates to the field of food processing equipment technology, and in particular to a sauce mixing mechanism for maintaining the uniformity of sauce in Chinese cooking, applicable to automated cooking machines, catering production lines and other scenarios.

[0003] In Chinese culinary techniques, the preparation and use of thickening sauce is a crucial step in enhancing the taste, color, and flavor of dishes. Thickening sauce is typically made by mixing starch with water and broth, and its uniformity directly affects the thickening effect. If the sauce settles, separates, or clumps, it will result in uneven thickness in certain areas, negatively impacting the cooking quality. With the increasing demand for automation and standardization in the catering industry, automated cooking machines and intelligent cooking equipment are becoming more widespread. These devices place higher demands on the continuous uniformity of thickening sauce, requiring specialized systems to dynamically adjust the sauce during storage and use.

[0004] Currently, existing starch slurry mixing techniques have the following drawbacks:

[0005] Firstly, traditional manual stirring relies on continuous human operation, which is not only inefficient but also makes it difficult to ensure the stability of the sauce's uniformity, thus failing to meet the continuous operation requirements of automated cooking equipment.

[0006] Secondly, some automated equipment uses a mechanical stirring structure with a built-in stirring paddle, which is directly immersed in the starch slurry for rotation and stirring. This type of structure has obvious shortcomings: on the one hand, the direct contact between the stirring paddle and the starch slurry can easily cause the starch slurry to adhere to the surface of the paddle blade, forming lumps or residues, affecting the purity of the subsequent starch slurry; on the other hand, the rotation range of the stirring paddle is limited, which can easily form stirring dead zones at the bottom or corners of the material box, leading to local sedimentation of the starch slurry, especially for high-concentration starch slurry, making it difficult to ensure uniform stirring.

[0007] Third, existing starch slurry processing devices that use pump-based circulation lack targeted flow-guiding structures in their inlet and outlet pipeline designs. For example, the outlet is mostly a direct-injection nozzle, where the sprayed starch slurry only forms turbulence in a localized area and cannot drive the starch slurry in the hopper to form an overall circulating vortex, resulting in poor circulation and stirring effects and significant differences in concentration between the upper and lower layers of starch slurry.

[0008] Fourth, some circulation systems do not take into account the directional design of the starch slurry flow. During the circulation process, the flow path of the starch slurry in the container is chaotic. This not only fails to enhance the mixing effect, but may also cause the starch slurry to splash or produce too many bubbles due to excessive local flow velocity, affecting the physical properties of the starch slurry. Utility Model Content

[0009] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide a thickening mechanism, a thickening device, and a cooking machine to solve the problems of low efficiency, easy sedimentation of thickening sauce, and uneven thickening sauce caused by easy stratification in the existing thickening technology.

[0010] To solve the above-mentioned technical problems, this utility model provides a starch slurry mixing mechanism to maintain the uniformity of the starch slurry; comprising:

[0011] A container, in which the thickening sauce is contained;

[0012] The circulating pump set includes a circulating pump, a feed pipe connected at one end to the inlet of the circulating pump, and a discharge pipe connected at one end to the outlet of the circulating pump. The other ends of the feed pipe and the discharge pipe extend into the material box. The circulating pump pumps the starch slurry into the circulating pump through the feed pipe, and then pumps the starch slurry into the material box through the discharge pipe to form a circulation.

[0013] A stirring nozzle is sleeved on the discharge end of the discharge pipe. The stirring nozzle is obliquely arranged towards the side wall of the material box. After the starch slurry is sprayed out from the stirring nozzle, it flows along the tangential direction of the side wall of the material box, forming a stirring vortex that drives the starch slurry in the material box to rotate as a whole.

[0014] As a more preferred method, the discharge pipe and the inlet pipe extend vertically downwards to the bottom of the material box. The advantage of this is that the discharge pipe and the inlet pipe extend vertically downwards to the bottom of the material box, which allows the circulating pump to draw the starch slurry at the bottom of the material box to participate in the circulation, while sending the circulated starch slurry back to the bottom. This ensures that the starch slurry at different depths in the material box can be fully stirred and circulated, preventing the starch slurry at the bottom from settling and becoming unable to participate in the flow. This further improves the overall uniformity of the starch slurry and ensures the thoroughness of the stirring effect.

[0015] As a more preferred embodiment, the stirring nozzle is a right-angle elbow, with one end vertically upward and connected to the discharge pipe, and the other end horizontal and inclined towards the side wall of the material box. The advantage of this design is that the right-angle elbow, with one end vertically upward and connected to the discharge pipe, and the other end horizontal and inclined towards the side wall of the material box, allows for more precise control of the direction of the gravy spray, ensuring that the gravy flows tangentially along the side wall, thereby stably forming a stirring vortex. The right-angle elbow design is simple and easy to install, ensuring the impact force and flow stability of the gravy during spraying, enhancing the stirring effect of the vortex, and making the gravy mix more evenly.

[0016] As a preferred method, the outlet diameter of the stirring nozzle is smaller than the inlet diameter, increasing the outlet flow rate of the starch slurry. The beneficial effect is that, according to fluid mechanics principles, this smaller outlet diameter increases the outlet flow rate of the starch slurry. The faster flow rate results in a stronger impact force when the starch slurry is ejected, more effectively creating a vortex within the mixing box, enhancing the stirring intensity and range, accelerating the mixing speed, further improving the uniformity of the starch slurry, and also increasing the efficiency of the circulating stirring.

[0017] As a more preferred embodiment, the material box includes a base box and a lid that covers the base box. The advantage of this is that the material box, composed of a base box and a lid, allows the lid to close securely on the base box, providing a seal and preventing the thickening sauce from overflowing due to splashing during the stirring and circulation process, thus maintaining a clean working environment. Simultaneously, the sealed structure reduces the contact between the thickening sauce and outside air, lowering the risk of contamination and helping to maintain the quality of the thickening sauce.

[0018] As a more preferred embodiment, the cover is equipped with a first adapter and a second adapter. The lower ends of the first and second adapters are connected to the feed pipe and the discharge pipe, respectively, and the upper ends are connected to the inlet and outlet of the circulation pump, respectively. The advantage of this is that the first and second adapters on the cover connect the feed pipe, the discharge pipe, and the inlet and outlet of the circulation pump, respectively, making the pipeline connections more organized and avoiding the inconvenience of installation and maintenance caused by messy pipelines. The adapters also facilitate the connection and disassembly of the feed pipe, the discharge pipe, and the circulation pump, making equipment inspection and component replacement easier and improving equipment maintenance convenience.

[0019] As a preferred method, the discharge and inlet pipes are made of rigid materials to avoid fluctuations in the discharge and inlet pipes caused by the flow of starch slurry. The advantages are that the rigid materials used in the discharge and inlet pipes can resist the impact force generated by the flow of starch slurry, preventing the pipes from changing position or shape due to fluctuations, thus ensuring the stability and accuracy of the starch slurry circulation. At the same time, the rigid material is not easily deformed, extending the service life of the pipes, reducing malfunctions caused by pipe damage, and improving the overall reliability of the equipment.

[0020] As a more preferred method, the upper ends of the first adapter and the second adapter are respectively connected to the inlet and outlet of the circulating pump via hoses. The advantage of this method is that the upper ends of the first adapter and the second adapter are connected to the inlet and outlet of the circulating pump via hoses. The hoses have good flexibility and can adapt to the slight vibrations that may be generated when the circulating pump is working. This avoids the problem of stress concentration in the pipeline caused by hard connection, protects the connection parts of the pipeline and the adapter, reduces wear and leakage risk at the connection, and also facilitates the position adjustment and installation layout between the circulating pump and the material box.

[0021] To solve the above problems, this utility model also provides a thickening device, including: the above-mentioned thickening sauce mixing mechanism; and a pump, wherein the inlet of the pump is connected to the material box of the thickening sauce mixing mechanism, and the outlet of the pump is used to spray the thickening sauce.

[0022] To solve the above problems, this utility model also provides a cooking machine, including the above-mentioned thickening device.

[0023] As described above, the sauce mixing mechanism, thickening device, and cooking machine of this invention have the following beneficial effects:

[0024] The thickening sauce mixing mechanism of this invention uses a circulating pump to circulate the thickening sauce in the container. Combined with angled stirring nozzles, the sauce flows tangentially along the side wall of the container after being sprayed from the nozzles, forming a stirring vortex. This ensures comprehensive and continuous mixing of the sauce within the container. This design effectively avoids problems such as sedimentation and stratification caused by static standing, maintaining the uniformity of the sauce and ensuring consistent taste and quality during thickening. Furthermore, the circulating flow eliminates the need for manual stirring, saving labor costs and improving work efficiency.

[0025] This invention relates to a thickening device that combines a thickening sauce mixing mechanism with a pump to form a thickening system. The thickening sauce mixing mechanism continuously maintains the uniformity of the thickening sauce, while the pump draws the uniform thickening sauce from the container and sprays it out, thus automating the thickening process. This design ensures that the sprayed thickening sauce has a uniform concentration, resulting in consistent thickening effects on dishes and improving the stability of dish quality. Simultaneously, the automated operation improves work efficiency in scenarios such as stir-frying.

[0026] This invention relates to a cooking machine that incorporates a thickening device. During the cooking process, this device automatically sprays a uniform thickening sauce, eliminating the need for manual thickening and reducing manual steps, thus increasing the automation level of the cooking machine. Simultaneously, the uniform thickening sauce ensures a more even flavor in the dishes, improving the quality and taste of the food prepared by the cooking machine, and enhancing its practicality and market competitiveness.

[0027] In summary, the thickening and mixing mechanism, thickening device, and cooking machine of this invention use a circulating pump to circulate the thickening liquid in the feed box, and with the addition of an angled stirring nozzle, achieve long-term homogenization of the thickening liquid. This solves the problems of low efficiency, easy sedimentation, and uneven thickening liquid caused by easy stratification in existing thickening and mixing technologies. Attached Figure Description

[0048] like Figure 1 as well as Figure 2 As shown, this utility model provides a starch slurry mixing mechanism to maintain the uniformity of the starch slurry; comprising:

[0049] Material box 1, the thickening sauce is contained in the material box 1;

[0050] The circulating pump group 2 includes a circulating pump 21, a feed pipe 22 connected to the inlet of the circulating pump 21 at one end, and a discharge pipe 23 connected to the outlet of the circulating pump 21 at one end. The other ends of the feed pipe 22 and the discharge pipe 23 extend into the material box 1. The circulating pump 21 pumps the starch slurry into the circulating pump 21 through the feed pipe 22, and then pumps the starch slurry into the material box 1 through the discharge pipe 23 to form a circulation.

[0051] A stirring nozzle 3 is sleeved on the discharge end of the discharge pipe 23. The stirring nozzle 3 is obliquely arranged towards the side wall of the material box 1. After the starch slurry is sprayed out from the stirring nozzle 3, it flows along the tangential direction of the side wall of the material box 1, forming a stirring vortex that drives the starch slurry in the material box 1 to rotate as a whole.

[0052] To better illustrate the thickening sauce mixing mechanism of this invention, its specific application is described below. The thickening sauce mixing mechanism uses a circulating pump unit 2 to circulate the thickening sauce within the material box 1. Combined with an angled stirring nozzle 3, the thickening sauce flows tangentially along the side wall of the material box 1 after being sprayed from the nozzle, forming a stirring vortex. This ensures comprehensive and continuous mixing of the thickening sauce within the material box 1. This design effectively avoids sedimentation and stratification problems caused by static standing, maintaining the uniformity of the thickening sauce and ensuring consistent taste and quality during thickening. Furthermore, the circulating flow eliminates the need for manual stirring, saving labor costs and improving work efficiency.

[0053] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 2 As shown, the discharge pipe 23 and the inlet pipe 22 extend vertically downwards to the bottom of the material box 1. The beneficial effect is that the discharge pipe 23 and the inlet pipe 22 extend vertically downwards to the bottom of the material box 1, so that the circulating pump group 2 can draw the starch slurry at the bottom of the material box 1 to participate in the circulation, and at the same time send the circulated starch slurry back to the bottom, ensuring that the starch slurry at different depths in the material box 1 can be fully stirred and circulated, avoiding the starch slurry at the bottom from settling and being unable to participate in the flow, further improving the overall uniformity of the starch slurry, and ensuring the thoroughness of the stirring effect.

[0054] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 2As shown, the stirring nozzle 3 is a right-angle elbow. One end of the right-angle elbow is vertically upward and connected to the discharge pipe 23, while the other end is horizontal and inclined towards the side wall of the material box 1. Its advantage lies in the fact that the right-angle elbow structure, with one end vertically upward and connected to the discharge pipe 23, and the other end horizontal and inclined towards the side wall of the material box 1, allows for more precise control of the direction of the gravy spray, ensuring that the gravy flows tangentially along the side wall, thereby stably forming a stirring vortex. The right-angle elbow design is simple and easy to install, ensuring the impact force and flow stability of the gravy during spraying, enhancing the stirring effect of the vortex, and making the gravy mix more evenly.

[0055] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 2 As shown, the outlet diameter of the stirring nozzle 3 is smaller than the inlet diameter, increasing the flow rate of the starch slurry at the outlet. The beneficial effect is that, according to fluid mechanics principles, the smaller outlet diameter of the stirring nozzle 3 increases the flow rate of the starch slurry at the outlet. This faster flow rate results in a stronger impact force when the starch slurry is ejected, more effectively driving the starch slurry within the material box 1 to form a vortex, enhancing the stirring force and range, accelerating the mixing speed of the starch slurry, further improving the uniformity of the starch slurry, and also increasing the efficiency of the circulating stirring.

[0056] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 2 As shown, the material box 1 includes a base box 11 and a lid 12 that covers the base box 11. Its advantages are that the material box 1, composed of the base box 11 and the lid 12, allows the lid 12 to close onto the base box 11, providing a seal and preventing the thickening sauce from overflowing due to splashing during the stirring and circulation process, thus maintaining a clean working environment. Simultaneously, the sealed structure reduces the contact between the thickening sauce and outside air, lowering the risk of contamination and helping to maintain the quality of the thickening sauce.

[0057] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 2 As shown, the cover 12 is equipped with a first adapter 121 and a second adapter 122. The lower ends of the first adapter 121 and the second adapter 122 are connected to the feed pipe 22 and the discharge pipe 23, respectively, and the upper ends are connected to the inlet and outlet of the circulating pump 21, respectively. The advantage is that the first adapter 121 and the second adapter 122 on the cover 12 connect the feed pipe 22, the discharge pipe 23, and the inlet and outlet of the circulating pump 21, respectively, making the pipeline connections more orderly and avoiding the inconvenience of installation and maintenance caused by messy pipelines. The adapters also facilitate the connection and disassembly between the feed pipe 22, the discharge pipe 23, and the circulating pump 21, making equipment maintenance and component replacement easier and improving the convenience of equipment maintenance.

[0058] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 2 As shown, the discharge pipe 23 and the inlet pipe 22 are made of rigid material to prevent fluctuations in the discharge pipe 23 and the inlet pipe 22 caused by the flow of starch slurry. The beneficial effect is that the rigid material of the discharge pipe 23 and the inlet pipe 22 can resist the impact force generated by the flow of starch slurry, preventing the pipeline from changing position or shape due to fluctuations, thus ensuring the stability and accuracy of the starch slurry circulation. At the same time, the rigid material is not easily deformed, extending the service life of the pipeline, reducing malfunctions caused by pipeline damage, and improving the overall reliability of the equipment.

[0059] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 2 As shown, the upper ends of the first adapter 121 and the second adapter 122 are respectively connected to the inlet and outlet of the circulating pump 21 via hoses 5. The beneficial effect is that the upper ends of the first adapter 121 and the second adapter 122 are connected to the inlet and outlet of the circulating pump 21 via hoses 5. The hoses 5 have good flexibility and can adapt to the slight vibration that may be generated when the circulating pump 21 is working. This avoids the problem of stress concentration in the pipeline caused by hard connection, protects the connection parts of the pipeline and the adapter, reduces wear and leakage risk at the connection, and also facilitates the position adjustment and installation layout between the circulating pump 21 and the material box 1.

[0060] To solve the above problems, this utility model also provides a thickening device, including: the above-mentioned thickening sauce mixing mechanism; and a pump 4, wherein the inlet of the pump 4 is connected to the material box 1 of the thickening sauce mixing mechanism, and the outlet of the pump 4 is used to spray the thickening sauce.

[0061] To better illustrate the thickening device of this invention, its specific application is described below: This thickening device combines a slurry mixing mechanism with a pump 4 to form a thickening apparatus. The slurry mixing mechanism continuously maintains the uniformity of the slurry, while the pump 4 extracts the uniform slurry from the container 1 and sprays it out, thus automating the thickening process. This design ensures that the sprayed slurry has a uniform concentration, resulting in consistent thickening effects on the dishes and improving the stability of dish quality. Simultaneously, the automated operation improves work efficiency in scenarios such as stir-frying.

[0062] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 2As shown, a third adapter 123 is provided on the box cover 12. The lower end of the third adapter 123 is connected to the extraction tube, which extends vertically downward to the bottom of the material box 1 and is also made of rigid material. The upper end of the third adapter 123 is connected to the inlet of the extraction pump 4 via a flexible hose 5. Its advantages are that the extraction tube connected to the third adapter 123, extending vertically downward to the bottom of the material box 1 and made of rigid material, can extract the gravy from the bottom of the material box 1, avoiding excessive gravy residue and waste. The rigid material extraction tube has good stability and will not shake due to the flow of gravy or the operation of the extraction pump 4, ensuring the smoothness of the extraction process. Simultaneously, the connection to the extraction pump 4 via the flexible hose 5 also buffers vibration, protects the connection parts, and improves the reliability of the extraction pump 4.

[0063] To solve the above problems, this utility model also provides a cooking machine, including the above-mentioned thickening device.

[0064] To better illustrate the cooking machine of this invention, its specific application is described below: This cooking machine incorporates a thickening device. During the cooking process, this device automatically sprays a uniform thickening sauce, eliminating the need for manual thickening and reducing manual steps, thus increasing the automation level of the machine. Simultaneously, the uniform thickening sauce ensures a more even flavor in the dishes, improving the quality and taste of the food prepared by the machine, and enhancing its practicality and market competitiveness. In summary, the thickening sauce mixing mechanism, thickening device, and cooking machine of this invention, through the circulation pump group 2 driving the thickening sauce in the material box 1 to circulate, combined with the angled stirring nozzles 3, achieve long-term homogenization of the thickening sauce, solving the problems of low efficiency, easy sedimentation, and uneven thickening sauce caused by stratification in existing thickening sauce mixing technologies.

[0065] As described above, the sauce mixing mechanism, thickening device, and cooking machine of this invention have the following beneficial effects:

[0066] 1. Stir continuously until the sauce is evenly mixed.

[0067] The thickening sauce mixing mechanism drives the thickening sauce in the material box 1 to circulate through the circulating pump group 2. In conjunction with the inclined stirring nozzle 3, the thickening sauce flows along the tangential direction of the side wall of the material box 1 to form a stirring vortex, which is fully and continuously stirred to avoid sedimentation and stratification of the thickening sauce, maintain uniformity, improve the quality of thickening, save manpower, and improve efficiency.

[0068] 2. Insert the pipe deep into the bottom and mix thoroughly.

[0069] The discharge pipe 23 and the feed pipe 22 extend vertically downward to the bottom of the material box 1, ensuring that the circulating pump group 2 can draw and send back the bottom starch slurry, so that starch slurry at different depths can fully participate in the circulating stirring, avoid bottom sedimentation, further improve overall uniformity, and ensure stirring effect.

[0070] 3. Right-angle elbow nozzle, stabilizing vortex

[0071] The stirring nozzle 3 adopts a right-angle elbow design, with one end vertically upward connected to the discharge pipe 23, and the other end horizontally inclined towards the side wall of the material box 1, which precisely controls the direction of the starch slurry spray, stably forms a stirring vortex, enhances the stirring effect, and makes the starch slurry mix more evenly.

[0072] 4. Narrow nozzle enhances flow rate and mixing force.

[0073] The outlet diameter of the stirring nozzle 3 is smaller than the inlet diameter. Based on the principle of fluid mechanics, this increases the flow rate of the starch slurry, enhances the spraying impact, and drives the starch slurry in the material box 1 to form a stronger vortex, thereby accelerating the mixing speed, improving the uniformity, and increasing the circulation mixing efficiency.

[0074] 5. Seal material box 1 to prevent splashing and contamination.

[0075] The material box 1 consists of a base box 11 and a lid 12. The lid 12 is sealed to prevent the starch slurry from splashing out during the stirring and circulation process, keeping the working environment clean, reducing the contact between the starch slurry and the outside air, reducing the risk of contamination, and maintaining the quality of the starch slurry.

[0076] 6. The adapter neatly organizes the piping and facilitates maintenance.

[0077] The cover 12 is equipped with first and second adapters 122, which are respectively connected to the feed pipe 22, the discharge pipe 23 and the inlet and outlet of the circulating pump 21, so that the pipeline connection is neat and orderly, which facilitates installation, maintenance and component replacement, and improves the convenience of equipment maintenance.

[0078] 7. Rigid piping for stable circulation

[0079] The discharge pipe 23 and the feed pipe 22 are made of rigid materials to resist the impact of the starch flow, avoid pipeline fluctuations, ensure the stability and accuracy of the circulating flow, extend the service life of the pipeline, and improve the reliability of the equipment.

[0080] 8. Flexible hose connection 5, for vibration damping.

[0081] The upper ends of the first and second adapters 122 are connected to the inlet and outlet of the circulation pump 21 via hoses 5. The flexibility of the hoses 5 adapts to the vibration of the circulation pump 21, avoids stress concentration, reduces wear and leakage risks, and facilitates position adjustment and installation layout.

[0082] 9. Automated thickening equipment improves dish quality.

[0083] The thickening device combines a thickening sauce mixing mechanism and an extraction pump 4 to automate the thickening process. The extraction pump 4 sprays the thickening sauce evenly to ensure consistent thickening concentration, improve the stability of dish quality, and increase work efficiency.

[0084] 10. Integrated cooking machine enhances automation and quality.

[0085] The cooking machine integrates a thickening device that automatically sprays evenly thickening sauce, reducing manual operation, increasing automation, ensuring uniform flavor in dishes, and enhancing the cooking machine's practicality and market competitiveness.

[0086] This invention's thickening and mixing mechanism, thickening device, and stir-fry machine achieve efficient circulation and mixing of the thickening sauce through a circulating pump group 2 and an inclined stirring nozzle 3, effectively solving the problems of easy sedimentation, layering, and low mixing efficiency of the thickening sauce in existing technologies. Its ingenious design, combined with optimized measures such as a sealed material box 1, rigid pipelines, and flexible hose connections 5, further enhances the stability and reliability of the equipment. The integrated application of the thickening device and stir-fry machine automates the thickening process, significantly improving dish quality and work efficiency, demonstrating significant practicality and market competitiveness.

[0087] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0088] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model.
