[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention solves the problem of uneven steam distribution in traditional sterilizers through the synergistic effect of the preheating component and the steam distribution component. The preheating component uses the closed-loop control of the heat-conducting tube, the heating ring and the temperature sensor to accurately preheat the inside of the tank, eliminating the problem of steam liquefaction caused by the cold start of the tank in traditional equipment, ensuring that the temperature of the steam is stable when it enters the tank, and avoiding the uneven distribution of steam caused by the liquefaction of steam due to the temperature difference; and the steam distribution duct on the steam distribution component will evenly distribute the steam in the tank, and use the Venturi effect to accelerate the nozzle, increase the steam flow rate and diffusion range, and promote the high-temperature steam to further evenly cover all areas in the tank, so that the sterilization uniformity is significantly improved, and the local sterilization failure caused by uneven steam distribution in traditional equipment is avoided.

[0018] 2. The present invention optimizes the dynamic distribution effect of steam by setting a Venturi effect acceleration nozzle. The nozzle provides additional power to the steam through the Venturi effect. Compared with the traditional fixed aperture nozzle, this design increases the steam flow rate and enhances its diffusion capacity, allowing the high-temperature steam to quickly penetrate the agricultural products in the breathable storage box, avoiding the local sterilization dead corners caused by insufficient steam flow rate in traditional equipment, and reasonably controlling the steam flow path, reducing energy waste, and improving the economy of the sterilization process.

[0023] See also Figure 1-Figure 8 A high-temperature steam sterilizer comprises a base 1 and a tank body 2 fixedly mounted on the base 1, a steam generating mechanism 3 is arranged on the top of the base 1, a steam distribution mechanism 4 is arranged in the inner cavity of the tank body 2, and a sealing placement mechanism 5 is arranged on the top of the tank body 2.

[0024] The steam distribution mechanism 4 includes a preheating component 41 and a steam distribution component 42 .

[0025] In some embodiments, see Figure 1-Figure 3 and Figure 6-Figure 7Structural schematic diagram, the preheating component 41 includes a heat-conducting tube 411 fixedly installed at the bottom of the inner cavity of the tank body 2, and a plurality of heating rings 412 located between the tank body 2 and the heat-conducting tube 411 are fixedly installed on the outer circumference of the heat-conducting tube 411. The plurality of heating rings 412 are connected by conductive columns, wherein a small electrical connection seat penetrating the tank body 2 is fixedly installed on the outer circumference of the conductive column; the tank body 2 is made of double-layer materials, which are 316L stainless steel layer and ceramic fiber blanket layer from outside to inside, a plurality of temperature sensors 413 are fixedly installed on the inner wall of the heat-conducting tube 411, and a plurality of heat-conducting parts 414 are fixedly installed on the inner circumference of the heat-conducting tube 411.

[0026] In this embodiment, after the steam generating mechanism 3 is started, a number of heating rings 412 are energized and heated through the conductive column and the small power connection seat, and the heat is transferred to the heat-conducting tube 411, and then the heat is evenly distributed inside the tank body 2 by the heat-conducting member 414. At the same time, the temperature sensor 413 monitors in real time and feeds back the temperature information to the controller 6 to ensure that the temperature inside the tank body 2 is always maintained within the preset range. The preheating component 41 is used to preheat the inside of the tank body 2, thereby avoiding the problem of uneven steam distribution caused by inappropriate temperature inside the tank, and improving the efficiency and effect of steam sterilization. At the same time, the double-layer material superposition structure (316L stainless steel layer and ceramic fiber blanket layer) adopted by the tank body 2 enhances the thermal insulation performance and further ensures the stability and efficiency of the sterilization process.

[0027] In some embodiments, see Figure 1-Figure 3 , Figure 6 and Figure 7 Structural schematic diagram, the steam distribution component 42 includes a plurality of conduit mounting parts 421 fixedly mounted on the bottom of the inner cavity of the heat-conducting tube 411 and penetrating the tank body 2 and the heat-conducting tube 411, a steam distribution conduit 422 connected to the inner cavity of the conduit mounting part 421 is fixedly mounted on the top of the conduit mounting part 421, and the steam distribution conduit 422 is made of stainless steel material, the steam distribution conduit 422 is adapted and fixedly connected to the heat-conducting part 414, and a plurality of Venturi effect acceleration nozzles 423 are fixedly mounted on the side of the steam distribution conduit 422 away from the inner circular surface of the heat-conducting tube 411.

[0028] Referring to the above description, the specific matching process of the components of this embodiment is as follows: The steam enters the steam distribution conduit 422 through the conduit mounting part 421. These conduits are evenly distributed in the tank body 2 in a circular shape. Then, the steam is ejected from the Venturi effect acceleration nozzle 423 on the steam distribution conduit 422. The Venturi effect is used to provide additional power for the steam, so that it can be more evenly covered on the sterilized items, and the steam flow rate is reasonably controlled to ensure that the steam can evenly penetrate into various areas in the tank. By optimizing the distribution and flow of steam, the utilization rate and sterilization effect of steam are improved, and the problem of incomplete sterilization or local overheating caused by uneven steam distribution is avoided, thereby ensuring the uniformity and efficiency of the sterilization process.

[0029] When used specifically, the working principle of the present invention is as follows: When the high-temperature steam sterilizer of the present invention is working, the preheating component 41 and the steam distribution component 42 work together to effectively solve the problem that uneven steam distribution affects the sterilization effect. Specifically, the preheating component 41 is fixedly installed on the bottom of the inner cavity of the tank body 2 through a heat-conducting tube 411 and several heating rings 412 on its outer cylindrical surface, and uses a conductive column and a small electrical connection seat to generate electricity (the preheating component 41 is controlled by the controller 6) to transfer heat to the heat-conducting tube 411. The double-layer material (316L stainless steel layer, ceramic fiber blanket layer) design of the tank body 2 enhances the thermal insulation effect. Several temperature sensors 413 on the inner wall of the heat-conducting tube 411 monitor the temperature in real time and feed back to the controller 6 to ensure that the temperature inside the tank body 2 is appropriate and uniform. At the same time, the heat-conducting member 414 on the inner cylindrical surface of the heat-conducting tube 411 evenly distributes the heat inside the tank body 2. The preheating process avoids partial liquefaction of steam due to inappropriate temperature when entering, which affects the steam distribution. Subsequently, the steam enters the steam distribution component 42, which evenly distributes the steam in the tank body 2 to ensure that the steam can cover every corner of the tank body 2. Specifically, the steam evenly enters the circularly distributed steam distribution duct 422 through the duct mounting member 421, and is finally ejected from the Venturi effect acceleration nozzle 423. The design of the Venturi effect acceleration nozzle 423 not only provides additional power for the steam so that the steam evenly covers the agricultural products, but also reasonably controls the steam flow rate to ensure that the steam evenly penetrates into each area of ​​the tank, thereby fully sterilizing each part of the agricultural products and significantly improving the sterilization effect.

[0030] In some embodiments, see Figure 1-Figure 3 and Figure 8 Structural diagram, the sealed storage mechanism 5 includes a sealing cover 51 bolted to the top of the tank body 2, a handle is fixedly installed on the top of the sealing cover 51 and directly above the motor 52, the motor 52 is fixedly installed at the center of the top of the sealing cover 51, the output end of the motor 52 passes through the sealing cover 51 and is fixedly installed with a shaft 53, the lower end of the shaft 53 is fixedly installed with a cross connecting frame 54, the end of the cross connecting frame 54 away from the shaft 53 is fixedly installed with a bottom frame 55, and the top of the bottom frame 55 is fixedly installed with A spiral dislocation frame 56, the inner circular surface of which is fixedly mounted with a plurality of breathable storage boxes 57, wherein the plurality of breathable storage boxes 57 are staggeredly mounted on the spiral dislocation frame 56, wherein the breathable storage boxes 57 are woven from a plurality of steel wires; a pressure monitoring gauge 58 located on one side of the motor 52 is fixedly mounted on the top of the sealing cover 51, a safety valve 59 and an air release valve 510 located on the other side of the motor 52 are fixedly mounted on the top of the sealing cover 51, and the safety valve 59 and the air release valve 510 are connected to the inner cavity of the tank body 2.

[0031] Referring to the above description, the specific matching process of the components of this embodiment is as follows: The controller 6 controls the motor 52 to start, and its output end drives the shaft 53 to rotate, and then drives the spiral offset frame 56 and the breathable storage box 57 installed offset thereon to rotate together through the cross connecting frame 54 and the base frame 55. This rotation design promotes the uniform penetration of steam into the agricultural products in the breathable storage box 57. At the same time, the pressure monitoring gauge 58 monitors the pressure changes inside the tank 2 in real time to ensure the safety and controllability of the sterilization process. Once the pressure is abnormal, the safety valve 59 will respond quickly and open automatically to release excess pressure and protect the safety of equipment and personnel. The staggered installation and wire braided structure of the breathable storage box 57 significantly improve the uniformity of steam distribution, ensure uniform distribution of heat and good circulation of steam, thereby improving the sterilization effect and avoiding local overheating or insufficient sterilization of agricultural products due to being in the same position for a long time. In addition, the breathable storage box 57 is staggered on the spiral staggered frame 56. Compared with the traditional overlapping placement, this cross-cage installation method significantly improves the uniformity of steam distribution, facilitates the circulation of steam in the tank body 2, and ensures uniform distribution of heat and good circulation of steam.

[0032] In some embodiments, see Figure 1-Figure 5 Structural schematic diagram, the steam generating mechanism 3 includes a water box 31 fixedly mounted on the top of the base 1 and located between the base 1 and the tank body 2, the top of the water box 31 is open, the connection between the water box 31 and the tank body 2, and the connection between the water heating element 34 and the water box 31 are both well sealed, and a water injection pipe 32 and a drainage pipe 33 connected to the inner cavity of the water box 31 are fixedly mounted on the water box 31 from top to bottom, and a water heating element 34 that penetrates the water box 31 is fixedly mounted on the bottom of the inner cavity of the water box 31, and the lower end of the water heating element 34 is fixedly connected to a large electrical connection seat that penetrates the base 1.

[0033] Referring to the above description, the specific matching process of the components of this embodiment is as follows: The steam generating mechanism 3 includes a water box 31 fixedly mounted on the top of the base 1 and located between the base 1 and the tank body 2. The top of the water box 31 is open, and the joints with the water box 31, the tank body 2, and the water heating element 34 are all well sealed. The water box 31 is provided with a water injection pipe 32 and a drainage pipe 33 connected to the inner cavity, which are convenient for water filling and drainage operations. The bottom of the water box 31 is fixedly installed with a water heating element 34 running through the inside thereof. The water heating element 34 is connected to the controller 6 through a large electrical connection seat. The controller 6 is connected to an external power supply, and the controller 6 controls the operation of the water heating element 34. When the steam generating mechanism 3 is started, the water heating element 34 transfers heat to the water in the water box 31, causing it to vaporize rapidly and generate a large amount of high-temperature steam. These high-temperature steams then enter the tank body 2 through the steam distribution mechanism 4 to perform high-temperature steam sterilization on the agricultural products. The design of the steam generating mechanism 3 ensures the high efficiency and stability of the sterilization process, and the cooperation of its sealing and the water heating element 34 ensures the efficiency of steam generation and transmission, thereby improving the sterilization effect. At the same time, the provision of the water filling pipe 32 and the drainage pipe 33 facilitates the filling and drainage of the water box 31 and is convenient for maintenance and operation.

[0034] Furthermore, the water heating element 34 includes a heating rod 341 , a plurality of heating fins 342 are fixedly mounted on the outer circumferential surface of the heating rod 341 , and a plurality of hemispherical heating protrusions 343 are fixedly mounted on the heating fins 342 .

[0035] Referring to the above description, the specific matching process of the components of this embodiment is as follows: A plurality of heating fins 342 are fixedly mounted on the outer surface of the heating rod 341, and a plurality of hemispherical heating protrusions 343 are further fixedly mounted on these heating fins 342. When the steam generating mechanism 3 is started, the current is transmitted to the water heating element 34 through the large electrical connection seat, and the heating rod 341, the heating fins 342 and the hemispherical heating protrusions 343 begin to generate heat. Such a design greatly increases the contact area between the water heating element 34 and the water, improves the heat transfer efficiency, and ensures that the heat can be quickly and evenly transferred to the water in the water box 31, so that it quickly vaporizes and generates a large amount of high-temperature steam for use in the steam sterilizer. This process reflects the key role of the water heating element 34 in efficient heating and steam generation.

[0036] In some embodiments, see Figure 1-Figure 5 Structural schematic diagram, a controller 6 is fixedly installed on the front of the tank body 2, and the controller 6 is electrically connected to the temperature sensor 413, the water heating element 34 and the motor 52.

[0037] Referring to the above description, the specific matching process of the components of this embodiment is as follows: The controller 6 plays a regulatory role in the working process of the high-temperature steam sterilizer. It realizes the control of the entire sterilization process by being electrically connected with the temperature sensor 413, the water heating element 34 and the motor 52. During operation, the controller 6 receives the temperature information in the tank body 2 fed back by the temperature sensor 413 in real time, ensures that the preheating component 41 and the steam generating mechanism 3 work as required, and maintains a suitable and uniform temperature environment inside the tank body 2. At the same time, it controls the heating rod 341, the heating fins 342 and the hemispherical heating protrusion 343 of the water heating element 34 to work together, efficiently transfer heat to the water in the water box 31, so that it quickly vaporizes and produces a large amount of high-temperature steam. In addition, the controller 6 also instructs the motor 52 to start, drive the spiral dislocation frame 56 and the breathable storage box 57 thereon to rotate, and promote the uniform penetration of steam into agricultural products. During the entire sterilization process, the regulation of the controller 6 ensures the uniform distribution of steam, the stable control of temperature and the effective sterilization of agricultural products, thereby improving the sterilization efficiency and quality, and ensuring the safety and quality of agricultural products.
