Description

Technical Field

[0001] This invention relates to the field of food processing equipment, and more specifically, to an integrated device for mixing and cooling sauces with microwave-assisted sterilization function. Background Technology

[0002] Sauces require sterilization and cooling before bottling. Current processes often employ intermittent sterilization tanks or tubular heat treatment, followed by transfer of materials to a separate cooling tank for stirring and cooling after sterilization. This approach has several drawbacks: First, sterilization and cooling are handled by two separate systems, resulting in cumbersome material transfer, large equipment footprint, and high heat loss. Second, traditional heat sterilization often involves overall heating, making it difficult to process materials in sections continuously during sterilization, leading to uneven heating. Third, while microwave sterilization offers rapid heating and high efficiency, existing microwave devices are mostly single-tank units, disconnecting sterilization from downstream stirring and cooling processes. This can lead to secondary contamination during material transfer across equipment and poor temperature transitions. Fourth, the power systems for each process are independent, making it impossible to synchronously drive continuous operation of section sterilization and stirring / cooling using a single rotating component. Therefore, there is an urgent need for a device that integrates feeding, microwave-assisted sterilization, material transfer, and stirring / cooling into a single, continuously operating system.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

[0020] It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this application. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness or purpose of this application, should still fall within the scope of the technical content disclosed in this application.

Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this application.

[0021] The following is in conjunction with the appendix Figure 1-13 The present invention will be described in further detail below.

[0022] Example 1: like Figures 1-13As shown, an integrated sauce mixing and cooling device with microwave-assisted sterilization function includes: a feeding mechanism 1, a sterilization tank mechanism 2, a distributing wheel mechanism 3, a transfer pipe mechanism 4, a mixing mechanism 5, and a cooling tank mechanism 6; the distributing wheel mechanism 3 is rotatably connected to the sterilization tank mechanism 2 in a sealed manner, and the distributing wheel mechanism 3 divides the interior of the sterilization tank mechanism 2 into multiple sauce zones; one end of the feeding mechanism 1 is movably connected to the distributing wheel mechanism 3 to input sauce into the multiple sauce zones through the feeding mechanism 1; the other end of the feeding mechanism 1 is fixed to the outside of the sterilization tank mechanism 2; one end of the transfer pipe mechanism 4 is fixedly connected to the overflow outlet 201 above one side of the sterilization tank mechanism 2, and the other end of the transfer pipe mechanism 4 passes through the cooling tank mechanism 6; the mixing mechanism 5 is rotatably connected to the cooling tank mechanism 6, and the mixing mechanism 5 is drively connected to the distributing wheel mechanism 3. The sterilization tank mechanism 2 includes a horizontally placed tank body 202, with an overflow outlet 201 on one side. A microwave generator 203 is sealed to the top of the horizontally placed tank body 202, and a microwave transmission window is opened on the top of the horizontally placed tank body 202. Microwaves emitted by the microwave generator 203 enter the horizontally placed tank body 202 through the microwave transmission window. The horizontally placed tank body 202 is equipped with an automatic pressure relief and exhaust structure. The automatic pressure relief and exhaust structure automatically opens when the pressure inside the horizontally placed tank body 202 reaches a preset threshold to release the steam inside the chamber. The automatic pressure relief and exhaust structure includes a pressure relief port located at the top of the horizontally placed tank body 202 and a spring-loaded valve core that seals the pressure relief port. When the pressure inside the tank overcomes the spring force, the valve core lifts to release the pressure.

[0023] In operation, the integrated sauce mixing and cooling device of the present invention, which has a microwave-assisted sterilization function, divides the interior of the sterilization tank 2 into multiple sauce zones using a distributing wheel mechanism 3. Initially, the sauce is fed into the sauce zones of the sterilization tank 2 via the feeding mechanism 1. At this time, the height of the sauce in the sauce zones is lower than the height of the overflow outlet 201, preventing overflow. As the distributing wheel mechanism 3 continues to rotate within the sterilization tank 2, the sauce is mixed evenly within the sterilization tank 2. When a sauce section rotates with the dispensing wheel mechanism 3 to a position corresponding to the overflow outlet 201, microwaves emitted by the microwave generator 203, which is sealed and connected to the top of the horizontal tank 202, are transmitted into the horizontal tank 202 through the microwave transmission window at the top of the horizontal tank 202. The sauce at the top of the sauce section is effectively sterilized first. Then, the feeding mechanism 1 continuously injects sauce into the sauce section. The newly injected sauce lifts the sterilized sauce above, making it reach the height of the overflow outlet 201 and enter the transfer pipe mechanism 4 through the overflow outlet 201. Then, it is introduced into the cooling tank mechanism 6 through the transfer pipe mechanism 4. As the dispensing wheel mechanism 3 continues to rotate, the sauce area moves away from the overflow outlet 201 before being completely emptied. Only the sauce that has been microwave-sterilized at the top is output, while the sauce that was injected later and has not yet been effectively sterilized remains in the sauce area and continues to rotate with the dispensing wheel mechanism 3. When the sauce area rotates back to the corresponding position of the overflow outlet 201, the sauce above it is again sterilized by microwave irradiation and lifted out by the subsequently injected sauce. This cycle continues until the sauce is fully sterilized before it can be output through the overflow outlet 201. The sauce in multiple sauce areas undergoes the above process for sterilization and output. The sauce output to the cooling tank mechanism 6 is stirred by the stirring mechanism 5, which is driven and connected to the dispensing wheel mechanism 3, and then cooled by the cooling tank mechanism 6 before being discharged. In addition, the horizontal tank 202 is equipped with an automatic pressure relief and exhaust structure. When the pressure inside the horizontal tank 202 reaches a preset threshold due to steam generated by microwave heating, the automatic pressure relief and exhaust structure automatically opens to discharge the steam in the chamber, ensuring safe operation of the sterilization process.

[0024] This invention integrates the feeding mechanism 1, sterilization tank mechanism 2, distributing wheel mechanism 3, transfer pipe mechanism 4, stirring mechanism 5, and cooling tank mechanism 6 into one unit. Sterilization and cooling are continuously completed within the same device, eliminating the need for material transfer between equipment and reducing floor space and heat loss. The distributing wheel mechanism 3 divides the interior of the sterilization tank mechanism 2 into multiple sauce zones and mixes the sauces during continuous rotation. Combined with the irradiation of the microwave generator 203, the sauces are heated evenly, and the sterilization quality is stable. The microwave generator 203 irradiates through the microwave transmission window, ensuring that the sauces at the top of the sauce zones are effectively sterilized first. The sauces are then discharged through the overflow outlet 201 under the lifting effect of the subsequent continuous injection of sauces, achieving priority discharge of the sterilized sauces at the top and simultaneous sterilization and discharge. Due to the continuous rotation of the distributing wheel mechanism 3, the sauces in the sauce zones are not completely discharged. The microwave sterilization process begins with the overflow outlet 201 discharging only the sterilized sauce from the top. The sauce that is not yet fully sterilized continues to rotate with the distribution wheel mechanism 3, and is sterilized again upon reaching the same position before being discharged. This prevents the insufficiently sterilized sauce from being discharged short-circuited, ensuring thorough and reliable sterilization. After sterilization, the sauce is directly introduced into the cooling tank mechanism 6 through the overflow outlet 201 and the transfer pipe mechanism 4. It is then stirred and cooled by the stirring mechanism 5, which is connected to the distribution wheel mechanism 3, before being discharged. Sterilization and cooling are closely integrated, avoiding secondary contamination caused by exposure during transport. Furthermore, the same rotating component synchronously drives the zoned sterilization and stirring cooling, resulting in integrated power and coordinated operation. In addition, the automatic pressure relief and exhaust structure on the horizontal tank 202 automatically opens to release steam when the pressure inside the tank reaches a preset threshold, preventing overpressure during microwave sterilization and ensuring safe and reliable operation.

[0025] Example 2: like Figures 1-13 As shown, in an integrated sauce mixing and cooling device with microwave-assisted sterilization function according to the present invention, the dispensing wheel mechanism 3 includes: a guide sleeve 301, a cylindrical dispensing box 302, and a guide shaft 303 coaxially and fixedly connected from left to right; the guide sleeve 301 and the guide shaft 303 are respectively sealed and rotatably connected to the left and right end caps of the horizontal tank 202; the cylindrical dispensing box 302 is located inside the horizontal tank 202, and its left and right side surfaces slide against the inner surfaces of the left and right end caps of the horizontal tank 202. The cylindrical dispensing box 302 has multiple dispensing baffles 304 evenly fixed circumferentially on its outer circumferential surface. The outer ends of the dispensing baffles 304 are sealed and slidably fitted to the inner wall of the horizontal tank 202. Multiple sauce zones are formed between the outer circumferential surface of the cylindrical dispensing box 302, the inner wall of the horizontal tank 202, and between two adjacent dispensing baffles 304. Multiple dispensing holes 305 are evenly opened circumferentially on the cylindrical dispensing box 302. Each dispensing hole 305 communicates with a sauce zone and with the inner cavity of the guide sleeve 301. A driven pulley is fixed on the guide sleeve 301, and the driven pulley is connected to the driving pulley at the output end of the drive motor via a synchronous belt.

[0026] This embodiment specifically defines the structure and driving method of the distributing wheel mechanism 3 based on embodiment 1. The distributing wheel mechanism 3 is composed of a guide sleeve 301, a cylindrical distributing box 302, and a guide shaft 303, which are coaxially fixedly connected from left to right. The guide sleeve 301 and the guide shaft 303 are respectively sealed and rotatably connected to the left and right end caps of the horizontal tank body 202, forming a rotating shaft system supported at both ends and sealing the inside of the sterilization tank mechanism 2. A driven pulley is fixed on the guide sleeve 301. The driving pulley at the output end of the drive motor drives the driven pulley to rotate through a synchronous belt, thereby driving the guide sleeve 301, the cylindrical distributing box 302, and the guide shaft 303 to rotate as a whole. The cylindrical dispensing box 302 is located inside the horizontal tank 202. Its left and right sides slide and engage with the inner sides of the left and right end caps of the horizontal tank 202 to form an axial seal, preventing axial leakage of sauce between adjacent sauce areas. Multiple dispensing baffles 304 are evenly fixed circumferentially on the outer circumferential surface of the cylindrical dispensing box 302. Their outer ends are sealed and slide to engage with the inner wall of the horizontal tank 202, so that multiple independent sauce areas are formed between the outer circumferential surface of the cylindrical dispensing box 302, the inner wall of the horizontal tank 202, and two adjacent dispensing baffles 304. As the cylindrical dispensing box 302 rotates, it passes sequentially through the inlet position and the overflow outlet 201. During feeding, the sauce is fed into the inner cavity of the guide sleeve 301 through the feeding mechanism 1. Since each group of multiple feeding holes 305 evenly opened along the circumference of the cylindrical feeding box 302 is connected to a sauce area and is also connected to the inner cavity of the guide sleeve 301, as the cylindrical feeding box 302 rotates, each group is aligned with the discharge position of the feeding mechanism 1 in turn. The sauce enters the corresponding sauce area through the aligned feeding holes 305, realizing batch feeding to each sauce area. When each sauce zone rotates to the overflow outlet 201 position with the cylindrical dispensing box 302, as described in Example 1: the sauce at the top of the sauce zone is first sterilized by microwave irradiation through the microwave transmission window of the microwave generator 203, and then guided into the cooling tank mechanism 6 through the overflow outlet 201 and the transfer pipe mechanism 4 under the lifting of the continuously injected sauce; as the dispensing wheel mechanism 3 rotates continuously, the sauce zone rotates away before it is completely emptied, and only the upper layer of sterilized sauce is discharged, while the lower layer of sauce that has not been fully sterilized circulates with the rotation, and is sterilized again and discharged when it reaches the same position again, to ensure thorough sterilization.

[0027] The present invention has the following technical effects: First, the guide sleeve 301, the cylindrical dispensing box 302, and the guide shaft 303 are coaxially fixedly connected, and their two ends are respectively sealed and rotatably supported on the left and right end caps of the horizontal tank 202, ensuring stable rotation and reliable sealing of the inside of the sterilization tank mechanism 2, preventing sauce leakage; Second, the left and right sides of the cylindrical dispensing box 302 slide with the inner side of the end cap, and the outer end of the dispensing baffle 304 slides with the inner wall of the horizontal tank 202, forming a double seal in the axial and circumferential directions, making multiple sauce zones independent of each other, avoiding cross-contamination between adjacent sauce zones, and ensuring the accuracy of zoned sterilization; Third, the continuous and stable operation of the dispensing wheel mechanism 3 is achieved through the driven pulley on the guide sleeve 301, the synchronous belt, and the active pulley at the output end of the drive motor. The fixed rotation provides reliable power for zoned feeding, mixing and sterilization, and cyclic replenishment sterilization; fourth, the multi-group feeding holes 305 are evenly opened circumferentially, and each group is connected to a sauce area and to the inner cavity of the guide sleeve 301. As the cylindrical feeding box 302 rotates, each group is aligned with the feeding mechanism 1 to discharge, realizing batch feeding to each sauce area. Combined with the layered sterilization, lifting overflow and cyclic replenishment sterilization process of Example 1, it ensures that the sauce in each sauce area is fully sterilized before being discharged through the overflow outlet 201, and the sterilization is thorough and reliable; in addition, the feeding wheel mechanism 3 simultaneously undertakes multiple functions of zoning, feeding, mixing and transmission, with a high degree of structural integration. It is also connected to the stirring mechanism 5 for transmission, and the same rotating part synchronously drives sterilization and downstream stirring and cooling, making the system compact and coordinated in operation.

[0028] Example 3: like Figures 1-13 As shown, in an integrated sauce mixing and cooling device with microwave-assisted sterilization function according to the present invention, the feeding mechanism 1 includes: a feeding hopper 101 fixed to the side of a horizontal tank 202 by a bracket; the bottom of the feeding hopper 101 is connected to one end of a feeding horizontal pipe 102 via a right-angle bend; the middle part of the feeding horizontal pipe 102 is rotatably and sealed within a guide sleeve 301; the other end of the feeding horizontal pipe 102 is fixedly connected to the inlet of a feeding cylinder 103; the feeding cylinder 103 is rotatably and sealed within a cylindrical distributing box 302; and a feeding mechanism is provided at the top of the feeding cylinder 103. Outlet 104: When the cylindrical dispensing box 302 rotates so that its dispensing hole 305 moves above the feeding outlet 104, the sauce in the feeding cylinder 103 can enter the sauce area through the feeding outlet 104 and the dispensing hole 305. The feeding mechanism 1 also includes: a rotating shaft 105 coaxially fixedly connected to the guide shaft 303, on which a first feeding auger 106 and a second feeding auger 107 are fixed. The first feeding auger 106 is rotatably fitted inside the feeding horizontal pipe 102, and the second feeding auger 107 is rotatably fitted inside the feeding cylinder 103. The cooling tank mechanism 6 is arranged below the sterilization tank mechanism 2, so that the driven bevel gear at the upper end of the stirring tube 501 meshes with the transmission bevel gear at the right end of the guide shaft 303.

[0029] Based on the above embodiments, this invention specifically defines the structure and feeding process of the feeding mechanism 1. The feeding hopper 101 is fixed to the side of the horizontal tank 202 by a bracket, serving as a fixed inlet for the sauce and remaining stationary. After the sauce is added to the feeding hopper 101, it changes its flow direction under gravity through the right-angle bend at its bottom, changing from vertical to horizontal flow and entering one end of the feeding horizontal pipe 102. The middle part of the feeding horizontal pipe 102 is sealed and rotatably connected to the guide sleeve 301, and its other end is fixedly connected to the inlet of the feeding cylinder 103. Since the feeding hopper 101 is fixed, the feeding horizontal pipe 102 and the feeding cylinder 103 remain stationary relative to the distributing wheel mechanism 3. However, the guide sleeve 301 and the cylindrical distributing box 302 rotate in a sealed manner around the feeding horizontal pipe 102 and the feeding cylinder 103 when the distributing wheel mechanism 3 rotates. The sealed rotational connection and sealed rotational cooperation between the two ensures relative rotational freedom while preventing the sauce from leaking from the cooperation gap. The feeding cylinder 103 is located inside the cylindrical distributing box 302, and its top is provided with a feeding outlet 104. The feeding mechanism 1 also includes a rotating shaft 105 coaxially fixedly connected to the guide shaft 303. Since the guide shaft 303 rotates synchronously with the distributing wheel mechanism 3, the rotating shaft 105 rotates accordingly, and drives the first feeding auger 106 and the second feeding auger 107 fixed thereon to rotate synchronously. The first feeding auger 106 is rotatably fitted inside the feeding horizontal tube 102, and pushes the sauce entering the feeding horizontal tube 102 to the feeding cylinder 103 in a horizontal spiral direction. The second feeding auger 107 is rotatably fitted inside the feeding cylinder 103, and continues to push the sauce to the feeding outlet 104 at the top of the feeding cylinder 103. When the cylindrical dispensing box 302 rotates, causing a certain group of dispensing holes 305 on it to move directly above the feeding outlet 104, the sauce that has accumulated at the feeding outlet 104 through the spiral push in the feeding cylinder 103 enters the corresponding sauce area through the feeding outlet 104 and the dispensing hole 305 of that group; as the cylindrical dispensing box 302 continues to rotate, each group moves sequentially to the top of the feeding outlet 104 and connects with it, thereby realizing batch and sequential feeding to multiple sauce areas. When each sauce zone rotates with the cylindrical dispensing box 302 to the position of the overflow outlet 201, the sauce at the top of the sauce zone is first sterilized by microwave irradiation through the microwave transmission window of the microwave generator 203. Then, under the lifting of the continuously injected sauce, it is introduced into the cooling tank mechanism 6 through the overflow outlet 201 and the transfer pipe mechanism 4. As the dispensing wheel mechanism 3 continues to rotate, the sauce zone rotates away before it is completely emptied, and only the upper layer of sterilized sauce is discharged. The lower layer of sauce that has not been fully sterilized circulates with the rotation. When it reaches the position again, it is sterilized again and then discharged to ensure thorough sterilization.

[0030] This invention forms a feeding channel that is stationary relative to the distributing wheel mechanism 3 by fixing the feeding hopper 101 to the side of the horizontal tank 202 and connecting it to the feeding cylinder 103 located in the cylindrical distributing box 302 via a right-angle bend and the feeding horizontal pipe 102. Meanwhile, the guide sleeve 301 and the cylindrical distributing box 302 rotate in a sealed manner around the feeding horizontal pipe 102 and the feeding cylinder 103, achieving reliable coupling between fixed feeding and rotating distributing. The structure is compact, and the sealing at the joints prevents sauce leakage. The rotating shaft 105 is coaxially fixed with the guide shaft 303, and the rotation of the distributing wheel mechanism 3 synchronously drives the first feeding spire 106 and the second feeding spire 103. The feeding auger 107 does not require a separate feeding power source, resulting in high power integration. The two-stage augers are synchronously pushed within the feeding horizontal pipe 102 and the feeding cylinder 103, respectively, ensuring that the viscous sauce is stably and quantitatively delivered to the feeding outlet 104 at the top of the feeding cylinder 103, preventing blockages and ensuring continuous and reliable feeding. The feeding outlet 104 rotates with the cylindrical distribution box 302 and aligns with each group in sequence, enabling batch feeding to each sauce area. Combined with the layered sterilization, lifting overflow, and circulating replenishment sterilization process of Example 1, it ensures that the sauce in each sauce area is fully sterilized and discharged through the overflow outlet 201, ensuring thorough and reliable sterilization.

[0031] Example 4: like Figures 1-13As shown, in an integrated sauce mixing and cooling device with microwave-assisted sterilization function according to the present invention, the cooling tank mechanism 6 includes: a cooling tank body 601, a top cover 602 sealed to the top of the cooling tank body 601, a stirring mechanism 5 rotatably connected to the central through hole of the top cover 602, and the lower end of the stirring mechanism 5 inserted into the cooling tank body 601; a cooling material outlet 603 is provided above the side wall of the cooling tank body 601, and a tail material outlet 604 is provided at the bottom of the cooling tank body 601, with a detachable sealed plug inside the tail material outlet 604; a cooling jacket is provided on the outer wall of the cooling tank body 601, and a cooling cavity 605 for injecting coolant is formed between the cooling jacket and the cooling tank body 601, with the coolant inlet at the bottom of the cooling jacket and the coolant outlet above the side of the cooling jacket both communicating with the cooling cavity 605. The stirring mechanism 5 includes: a stirring tube 501 rotatably connected to the central through hole of the top cover 602; the stirring tube 501 is inserted into the tube body inside the cooling tank body 601 and fixed with multiple upper and lower stirring impellers 502; a driven bevel gear is fixed to the upper end of the stirring tube 501; a transmission bevel gear is fixed on the guide shaft 303, and the transmission bevel gear meshes perpendicularly with the driven bevel gear. The stirring mechanism 5 also includes: multiple inclined stirring rods 503 uniformly surrounding and fixed to the lower end of the stirring tube 501; the multiple inclined stirring rods 503 are fixedly connected to a bottom scraper 504 that slides and engages with the bottom surface inside the cooling tank body 601; the multiple bottom scrapers 504 are fixedly connected to a side wall scraper 505 that slides and engages with the inner wall of the cooling tank body 601. The transfer pipe mechanism 4 includes: an inclined pipe body 401, an elbow pipe body 402, and a vertical pipe body 403, which are fixedly connected in sequence; the inclined pipe body 401 is connected to the overflow outlet 201, and the horizontal height of the connection end is higher than the horizontal height of the connection end between the inclined pipe body 401 and the elbow pipe body 402; the middle part of the vertical pipe body 403 is sealed and rotatably fitted inside the stirring pipe 501, and the bottom of the vertical pipe body 403 extends to the bottom of the stirring pipe 501.

[0032] This embodiment, based on the above embodiment, specifically defines the structure and cooperative relationship of the cooling tank mechanism 6, the stirring mechanism 5, and the transfer pipe mechanism 4. The sauce output from the overflow outlet 201 of the sterilization tank mechanism 2 is sequentially introduced into the cooling tank mechanism 6 through the inclined pipe 401, the elbow pipe 402, and the vertical pipe 403 of the transfer pipe mechanism 4; wherein the horizontal height of the end of the inclined pipe 401 connected to the overflow outlet 201 is higher than that of the end connected to the elbow pipe 402, so that the sauce flows down along the inclined pipe 401 under the action of gravity, turns after the elbow pipe 402, and enters the vertical pipe 403 for downward conveying. The middle part of the vertical tube 403 is sealed and rotatably fitted inside the stirring tube 501 of the stirring mechanism 5, with its bottom extending below the stirring tube 501. The sauce is discharged from the bottom of the vertical tube 403 and falls into the cooling tank body 601. Since the vertical tube 403 is fixed with the transfer tube mechanism 4, the stirring tube 501 rotates around the vertical tube 403 in a sealed manner. The two rotate relative to each other while being sealed and fitted together, preventing the sauce from leaking from the fitting point. The top of the cooling tank body 601 is sealed and connected to the top cover 602, and the stirring tube 501 is sealed and rotatably connected to the central through hole of the top cover 602, with its lower end inserted into the cooling tank body 601. The rotational power of the stirring mechanism 5 comes from the distributing wheel mechanism 3: the guide shaft 303 rotates synchronously with the distributing wheel mechanism 3, driving the transmission bevel gear fixed on it to rotate. The transmission bevel gear meshes perpendicularly with the driven bevel gear fixed at the upper end of the stirring tube 501, converting the horizontal rotation into the vertical rotation, driving the stirring tube 501 to rotate. When the stirring tube 501 rotates, multiple upper and lower stirring impellers 502, fixed to it and inserted into the inner tube of the cooling tank body 601, stir the sauce inside the cooling tank body 601. Multiple inclined stirring rods 503, fixed to the lower end of the stirring tube 501, rotate with the stirring tube 501, stirring the sauce at the bottom and driving the bottom scraper 504, which is fixedly connected to it, to slide along the inner bottom surface of the cooling tank body 601, and the side wall scraper 505 to slide along the inner wall of the cooling tank body 601, scraping off the sauce that has settled and stuck to the wall. At the same time, the coolant enters the cooling chamber 605 from the coolant inlet at the bottom of the cooling jacket, rises along the cooling chamber 605 and exchanges heat with the sauce through the wall of the cooling tank body 601. After absorbing heat, it flows out from the coolant outlet above the side of the cooling jacket, forming a coolant flow path that enters from the bottom and exits from the top. The coolant fills the cooling chamber 605 from the bottom and exits from the top. Combined with the stirring of the stirring mechanism 5, the sauce and coolant exchange heat fully through the wall of the cooling tank body 601, resulting in high cooling efficiency and continuous cooling of the sauce. After being stirred and cooled, the sauce is discharged from the cooling material outlet 603 above the side wall of the cooling tank body 601; when the machine is stopped for cleaning, the blockage in the tail material outlet 604 at the bottom of the cooling tank body 601 is opened to discharge the residual tail material at the bottom.

[0033] This invention uses the inclined pipe 401, the elbow pipe 402, and the vertical pipe 403 of the transfer pipe mechanism 4 to gravity guide the sauce overflowing from the sterilization tank mechanism 2 into the cooling tank body 601. The vertical pipe 403 is sealed and rotatably fitted inside the stirring pipe 501, with its bottom extending below the stirring pipe 501 for discharge, forming a concentric structure of "inner pipe feeding, outer pipe stirring." This achieves continuous sauce introduction while avoiding interference between the transfer and stirring. The stirring mechanism 5 is driven by the guide shaft 303 via a vertical meshing of a transmission bevel gear and a driven bevel gear, converting the horizontal rotation of the distributing wheel mechanism 3 into the vertical rotation of the stirring pipe 501. No separate stirring power is required; it shares the same power source as the sterilization mechanism, resulting in a high degree of power integration. 1. Coordinated operation: Multiple upper and lower stirring impellers 502 on the stirring tube 501 thoroughly stir the sauce. The inclined stirring rod 503 at the lower end, the bottom scraper 504, and the side wall scraper 505 scrape off the deposited sauce on the bottom and inner wall of the cooling tank body 601 as the stirring tube 501 rotates, which enhances heat exchange and prevents sauce residue. The coolant enters the cooling chamber 605 from the coolant inlet at the bottom of the cooling jacket and flows out from the coolant outlet at the top side, so that the coolant fills the cooling chamber 605 and exchanges heat with the sauce in the opposite direction, resulting in high cooling efficiency. After cooling, the sauce is discharged through the cooled material outlet 603. When stopping the machine, the bottom tail material can be discharged by opening the plug of the tail material outlet 604, which is convenient for discharge and cleaning.

[0034] Example 5: like Figures 1-13 As shown, in the integrated sauce mixing and cooling device with microwave-assisted sterilization function of the present invention, the cooling tank mechanism 6 further includes: a circular seat 606 fixed in the middle of the bottom surface of the cooling tank body 601, the lower end of a one-way plug 607 is sealed and slidably connected inside the circular seat 606, and the lower end of the one-way plug 607 is fixedly connected to the bottom surface of the cooling tank body 601 through a pressure spring 608; the conical surface of the upper end of the one-way plug 607 is sealed and fitted to the bottom opening of the vertical tube 403.

[0035] This embodiment further defines the unidirectional discharge structure of the cooling tank mechanism 6 based on the above embodiment. A circular seat 606 is fixed in the middle of the bottom surface of the cooling tank body 601. The lower end of the unidirectional plug 607 is slidably connected to the circular seat 606, so that the unidirectional plug 607 can slide up and down along the axial direction of the circular seat 606 and maintain a seal with the circular seat 606. The lower end of the unidirectional plug 607 is fixedly connected to the bottom surface of the cooling tank body 601 through a pressure spring 608. The pressure spring 608 applies an upward elastic force to the unidirectional plug 607, so that the tapered surface at its upper end seals the bottom opening of the vertical tube 403 in the default state. During operation, the sterilized sauce, conveyed downwards through the vertical pipe body 403 of the transfer pipe mechanism 4, accumulates at the bottom of the vertical pipe body 403. When the downward pressure of the sauce overcomes the elastic force of the pressure spring 608 and the buoyancy of the sauce in the cooling tank body 601 on the one-way plug 607, it pushes the one-way plug 607 to slide downwards along the annular seat 606. Its upper conical surface separates from the bottom opening of the vertical pipe body 403, the opening is opened, and the sauce is discharged through the opened opening. The sauce enters the cooling tank body 601, is stirred by the stirring mechanism 5, and cooled by the coolant in the cooling chamber 605 before being discharged from the cooling material outlet 603. When the pressure of the sauce in the vertical tube 403 decreases, such as when feeding stops or decreases, the pressure spring 608 rebounds and pushes the one-way plug 607 to slide upwards and reset. Its upper conical surface re-seals the bottom opening of the vertical tube 403, preventing the sauce in the cooling tank body 601 from flowing back into the vertical tube 403. In this way, the sauce output from the sterilization tank mechanism 2 can only flow into the cooling tank body 601 unidirectionally through the vertical tube 403 and cannot flow back in reverse, ensuring the isolation between the sterilization section and the cooling section.

[0036] The one-way valve structure of the present invention, consisting of a circular seat 606, a one-way plug 607, and a pressure spring 608, has the following synergistic effects; First, this invention employs a continuous operation mode where the distributing wheel mechanism 3 rotates continuously and each sauce zone overflows sequentially. The sauce output from the sterilization tank mechanism 2 is a pulsed flow that overflows intermittently as the distributing wheel mechanism 3 rotates. Meanwhile, the sauce in the cooling tank mechanism 6 is in a state of dynamic disturbance under the continuous stirring of the stirring mechanism 5. Without unidirectional isolation, the cooled sauce in the cooling tank body 601 is easily backflowed into the sterilization tank mechanism 2 via the vertical pipe 403 due to liquid level differences, stirring disturbances, or pressure fluctuations. This causes the cooled sauce to mix with the unsterilized sauce, disrupting the layered sterilization process described in Example 1, where the upper layer is sterilized and discharged first, and the lower layer is circulated and replenished. The sterilization process is completely out of control. In this embodiment, the one-way plug 607, under the action of the pressure spring 608, defaults to blocking the bottom opening of the vertical pipe 403. It only opens to discharge when the pressure of the sauce in the vertical pipe 403 overcomes the elasticity of the pressure spring 608 and the buoyancy of the sauce in the cooling tank body 601. It automatically closes when the pressure decreases, thereby ensuring that the sauce in the sterilization tank mechanism 2 can only flow into the cooling tank body 601 in one direction and never flow back in the opposite direction. This maintains the stable operation of the layered sterilization and cyclic replenishment process, ensuring thorough and reliable sterilization. This is a technical requirement and unexpected effect that does not exist in segmented sterilization and cooling equipment, but is unique to the continuous integrated device of this invention.

[0037] Secondly, the pressure spring 608 enables the one-way plug 607 to adaptively respond to the pressure fluctuations caused by the pulse overflow in the sterilization section, realizing an adaptive discharge rhythm of discharge when there is material and closing when there is no material. There is no need to set up active control components such as sensors or solenoid valves. The structure is simple and the operation is reliable. In addition, the pressure spring 608 has a buffering effect on the pulse flow, making the sauce entering the cooling tank body 601 relatively stable and avoiding the impact of sudden changes in liquid level on the stirring and cooling.

[0038] Third, the tapered surface at the upper end of the one-way plug 607 and the bottom opening of the vertical tube 403 have an automatic centering function. Even if there is a slight deviation in the sliding of the one-way plug 607, the tapered surface can still fit and seal with the opening, ensuring reliable sealing. The annular seat 606 simultaneously serves the dual functions of guiding the sliding of the one-way plug 607 and sealing it. It not only restricts the one-way plug 607 to slide only along the axial direction and prevents deflection and jamming, but also prevents the sauce from leaking between the one-way plug 607 and the bottom surface of the cooling tank body 601, resulting in a high degree of structural integration.

[0039] Fourth, the cooling material outlet 603 is located above the side wall of the cooling tank body 601, so that the liquid level in the cooling tank body 601 does not exceed the height of the cooling material outlet 603, thereby limiting the maximum immersion depth of the one-way plug 607 and setting an upper limit on the buoyancy it experiences. Combined with the elasticity design of the pressure spring 608 and the downward action of the one-way plug 607's own weight, it ensures that the one-way plug 607 can reliably overcome buoyancy and slide down to open under the pressure of the sauce in the vertical tube 403, and will not become stuck or fail due to increased buoyancy, ensuring stable and reliable operation.
