Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a sterilization device for food processing. Background Art

[0002] In the food processing industry, sterilization is a key link in ensuring food safety and extending shelf life. Traditional sterilization equipment often has some shortcomings, such as incomplete sterilization, significant impact on food quality, complex operation, and high energy consumption.

[0003] On the one hand, some sterilization equipment cannot ensure that all parts of the food are heated evenly, resulting in the inability to completely kill microorganisms in some areas, affecting the sterilization effect; on the other hand, some equipment may destroy the nutritional content and taste of the food due to factors such as high temperature during the sterilization process, thereby reducing the quality of the food; at the same time, the existing sterilization equipment is not precise enough in the control of steam input and discharge, and steam leakage or external air entry may easily occur, affecting the stability and reliability of sterilization.

[0004] To this end, we propose a sterilization device for food processing. Utility Model Content

[0005] The main purpose of the present utility model is to provide a sterilization device for food processing, in order to prevent stability and reliability problems caused by incomplete sterilization, damage to food quality and inaccurate steam control, thereby improving the overall performance of the sterilization device for food processing, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A sterilization device for food processing, comprising a sterilization box, a pressure pipe and an exhaust pipe, wherein the pressure pipe and the exhaust pipe are respectively arranged horizontally at both ends of the sterilization box, a bracket is fixedly connected to the inner wall of the bottom end of the sterilization box and located between the pressure pipe and the exhaust pipe, a sterilization cylinder is rotatably connected to the inner side of the bracket through a bearing, a plurality of sterilization chambers are arranged in an annular array inside the sterilization cylinder, and a sealing door is rotatably connected to the plurality of sterilization chambers, a gear ring is provided on the outer wall of the sterilization cylinder, a drive motor is fixedly mounted on the outer wall of one side of the bracket, an output shaft of the drive motor is fixedly connected to a drive gear, one side of the drive gear extends into the bracket and meshes with the gear ring;

[0008] Both ends of the multiple sterilization chambers are provided with connecting pipes, and the inner walls of the ends of the pressure supply pipe and the exhaust pipe close to the connecting pipes are provided with supporting nets, and the inner walls of the ends of the connecting pipes away from the supporting nets are provided with protective nets. A spring bracket is fixedly provided on the inner wall of the connecting pipe close to the protective net, and a one-way blocking ring is fixedly provided on the inner wall of the connecting pipe close to the supporting net. An air hole is provided at the center of the one-way blocking ring, and a one-way blocking ball is movably provided at one end of the one-way blocking ring. A push column is inserted into the one-way blocking ball close to the inner side of the support net, and the outer end of the push column is designed as a curved surface. The diameter of the one-way blocking ball is larger than the diameter of the air hole. A spring is fixedly installed on one end of the spring bracket, and the other end of the spring is fixedly installed on the one-way blocking ball.

[0009] By adopting the above technical solution, in the preparation stage, the food to be sterilized is placed in each sterilization chamber and the sealing door is closed. At this time, the entire equipment is in a sealed state, ready for the subsequent sterilization process;

[0010] When the equipment is started, high-temperature steam enters the sterilization box through the pressure pipe. The steam first contacts the support net inside the connecting pipe at one end of the pressure pipe. The support net plays a certain role in filtering and stabilizing the steam flow. The steam pressure acts on the outside of the one-way blocking ball and the support net acts on the push column. Since the outer end of the push column is designed as a curved surface, the support net will push the push column inward, and then push the one-way blocking ball out of the air hole. At this time, the high-temperature steam is able to enter the sterilization chamber through the air hole. At the same time, the drive motor is started, and the output shaft of the drive motor drives the drive gear to rotate. Since the drive gear is engaged with the gear ring on the outer wall of the sterilization cylinder, it drives the sterilization cylinder to rotate on the inner side of the bracket through the bearing. In this way, the food in each sterilization chamber can be heated evenly, thereby improving the sterilization effect.

[0011] After the high-temperature steam enters the sterilization chamber, it sterilizes the food in the chamber. The high temperature of the steam can destroy the proteins, enzymes, cell membranes and nucleic acids of the microorganisms, making them inactive and thus achieving the purpose of sterilization. As the sterilization cylinder rotates continuously, the food in each sterilization chamber can fully contact the steam, ensuring comprehensive and thorough sterilization.

[0012] When the sterilization process is completed, the steam needs to be discharged. At this time, the one-way blocking ball in the connecting pipe at one end of the exhaust pipe blocks the air hole under the action of the spring to prevent external air from entering the sterilization chamber. The push column in the sterilization chamber, under the action of the support net, will push the one-way blocking ball to the side away from the exhaust pipe, so that the steam enters the connecting pipe through the air hole and is discharged from the exhaust pipe after being filtered by the protective net. The protective net can prevent impurities from entering the exhaust pipe and also play a certain role in buffering the steam flow. When the steam is discharged, the spring will push the one-way blocking ball to the air hole, blocking the air hole again, and preparing for the next sterilization process.

[0013] Furthermore, a heating barrel is fixedly installed on the inner wall of the bottom end of the sterilization box and is located directly below the pressure pipe, and a heating element is provided on the inner wall of the bottom end of the heating barrel.

[0014] By adopting the above technical solution, when the equipment is started, the heating element starts working, and the heating element converts electrical energy into thermal energy to heat the water in the heating barrel. As the heating progresses, the temperature of the water continues to rise. When it reaches a certain temperature, the water begins to boil and produces a large amount of high-temperature steam. Due to its low density, this high-temperature steam will move upward. As the steam rises, it gradually approaches the pressure pipe. Under the guidance of the pressure pipe, the steam enters the interior of the sterilization box, ready to sterilize the food in each sterilization cavity in the sterilization cylinder. Through the cooperation of the heating barrel and the heating element, high-temperature steam is continuously provided for the entire sterilization process, ensuring that the temperature and pressure conditions required for sterilization are met. This design enables the equipment to generate steam quickly and stably when sterilization is required, ensuring the efficient sterilization work.

[0015] Furthermore, a gas pipe is fixedly connected to the middle of the bottom end of the heating barrel.

[0016] By adopting the above technical solution, the gas pipe fixedly connected to the middle part of the bottom end of the heating barrel provides a specific output channel for the steam.

[0017] Furthermore, the top end of the gas pipe is fixedly connected to the bottom end of the outer wall of the pressure pipe, and the gas pipe is communicated with the pressure pipe.

[0018] By adopting the above technical solution, when the equipment is started, the heating element heats the water in the heating barrel, and the water boils to produce a large amount of high-temperature steam. The steam directly enters the pressure pipe through the gas pipe. By connecting the gas pipe and the pressure pipe, the flow and pressure of the steam can be better controlled to ensure that the steam enters the sterilization box in a stable state, thereby improving the stability and reliability of the sterilization process. At the same time, this connection method also makes the structure of the equipment more compact, reduces the energy loss of steam during transmission, and improves energy utilization efficiency.

[0019] Furthermore, a water supply pipe is fixedly connected to the upper portion of one end of the heating barrel away from the sterilization box, and the other end of the water supply pipe passes through one end of the sterilization box and extends to the outside.

[0020] By adopting the above technical solution, when the equipment has been running for a period of time, if the amount of water in the heating barrel is insufficient, water can be added to the heating barrel through the water adding pipe, and the external water source flows into the heating barrel through the water adding pipe. Under the guidance of the water adding pipe, the water can be accurately injected into the heating barrel. Since the connection position of the water adding pipe and the heating barrel is relatively high, interference with the heating element at the bottom of the heating barrel can be avoided during the water adding process, ensuring that the heating element can work continuously and stably; at the same time, the design of the water adding pipe passing through one end of the sterilization box and extending to the outside is convenient for the operator to add water at any time during the operation of the equipment without opening the sterilization box, thereby ensuring the continuity and stability of the sterilization process; in addition, combined with the one-way valve arranged inside the water adding pipe, it can prevent the water or steam in the heating barrel from flowing back through the water adding pipe during the operation of the equipment, ensuring the safety and reliability of the water adding process, and providing a strong guarantee for the equipment to continuously generate steam for sterilization operations.

[0021] Furthermore, one-way valves are provided inside the pressure pipe, exhaust pipe, gas pipe and water pipe.

[0022] By adopting the above technical solution, the one-way valve in the pressure pipe allows steam to flow from the heating barrel or the gas pipe to the sterilization cylinder in the sterilization box, preventing steam from flowing in the opposite direction, ensuring that steam can stably enter the sterilization chamber for sterilization operation, and ensuring a stable supply of steam pressure during the sterilization process;

[0023] The one-way valve in the exhaust pipe allows the sterilized steam to be discharged from the sterilization chamber to the outside, preventing external air from entering the sterilization chamber during the non-discharge phase, preventing external impurities and bacteria from contaminating the sterilized food, and also helps maintain the pressure balance in the sterilization chamber;

[0024] The one-way valve in the gas pipe ensures that steam can only flow from the heating barrel to the pressure pipe, preventing the steam in the pressure pipe from flowing back to the heating barrel, thus ensuring the unidirectional and stable steam delivery;

[0025] The one-way valve in the water filling pipe allows water to flow from the external water source into the heating barrel, while preventing the water or steam in the heating barrel from flowing out in the opposite direction during the operation of the equipment, ensuring the safety and stability of the water filling process and providing guarantee for the continuous generation of steam;

[0026] The setting of these one-way valves ensures the one-way flow of fluid in each pipeline of the equipment, improves the reliability and safety of equipment operation, and provides strong support for the effective sterilization of food.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] (1) The utility model relates to a sterilization device for food processing, which drives the sterilization cylinder to rotate through a driving motor so that the food in each sterilization chamber can be evenly heated, ensuring that the steam can fully contact all parts of the food. The high-temperature steam can effectively destroy the proteins, enzymes, cell membranes and nucleic acids of microorganisms, making the microorganisms inactive, thereby achieving the purpose of thorough sterilization.

[0029] (2) The utility model is a sterilization device for food processing.

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0036] In order to prevent incomplete sterilization, damage to food quality and stability and reliability problems caused by inaccurate steam control, and thus improve the overall performance of sterilization equipment for food processing, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, a sterilization device for food processing includes a sterilization box 1, a pressure pipe 2 and an exhaust pipe 3, the pressure pipe 2 and the exhaust pipe 3 are respectively arranged horizontally at the two ends of the sterilization box 1, and a bracket 4 is fixedly connected to the inner wall of the bottom end of the sterilization box 1 and located between the pressure pipe 2 and the exhaust pipe 3. A sterilization cylinder 5 is rotatably connected to the inner side of the bracket 4 through a bearing. The interior of the sterilization cylinder 5 is provided with a plurality of sterilization chambers 6 in an annular array, and a sealing door 8 is rotatably connected to the plurality of sterilization chambers 6. The outer wall of the sterilization cylinder 5 is provided with a gear ring 7, and a drive motor 9 is fixedly installed on the outer wall of one side of the bracket 4. The output shaft of the drive motor 9 is fixedly connected to a drive gear 10, and one side of the drive gear 10 extends into the bracket 4 and meshes with the gear ring 7;

[0037] Both ends of the multiple sterilization chambers 6 are provided with connecting pipes 12, and the inner walls of the pressure supply pipe 2 and the exhaust pipe 3 near the connecting pipe 12 are provided with a support net 11, and the inner walls of the connecting pipe 12 away from the support net 11 are provided with a protective net 18. A spring bracket 16 is fixedly provided on the inner wall of the connecting pipe 12 near the protective net 18, and a one-way blocking ring is fixedly provided on the inner wall of the connecting pipe 12 near the support net 11. An air hole 13 is provided at the center of the one-way blocking ring, and a one-way blocking ball 15 is movably provided at one end of the one-way blocking ring. A push column 14 is inserted into the one-way blocking ball 15 near the inner side of the support net 11, and the outer end of the push column 14 is a curved surface design. The diameter of the one-way blocking ball 15 is larger than the diameter of the air hole 13. A spring 17 is fixedly installed on one end of the spring bracket 16, and the other end of the spring 17 is fixedly installed on the one-way blocking ball 15.

[0038] When in use, in the preparation stage, the food to be sterilized is placed in each sterilization chamber 6 and the sealing door 8 is closed. At this time, the entire device is in a sealed state, ready for the subsequent sterilization process;

[0039] When the equipment is started, high-temperature steam enters the sterilization box 1 through the pressure pipe 2. The steam first contacts the support mesh 11 in the connecting pipe 12 at one end of the pressure pipe 2. The support mesh 11 plays a certain role in filtering and stabilizing the steam flow. The pressure of the steam acts on the outside of the one-way blocking ball 15 and the support mesh 11 acts on the pushing column 14. Since the outer end of the pushing column 14 is a curved surface design, the support mesh 11 will push the pushing column 14 inward, and then push the one-way blocking ball 15 out of the air hole 13. At this time, the high-temperature steam is able to enter the sterilization chamber 6 through the air hole 13. At the same time, the drive motor 9 is started, and the output shaft of the drive motor 9 drives the drive gear 10 to rotate. Since the drive gear 10 is engaged with the gear ring 7 on the outer wall of the sterilization cylinder 5, it drives the sterilization cylinder 5 to rotate on the inner side of the bracket 4 through the bearing. In this way, the food in each sterilization chamber 6 can be evenly heated, thereby improving the sterilization effect;

[0040] After the high-temperature steam enters the sterilization chamber 6, it sterilizes the food in the chamber. The high temperature of the steam can destroy the proteins, enzymes, cell membranes and nucleic acids of the microorganisms, making the microorganisms inactive and thus achieving the purpose of sterilization. As the sterilization cylinder 5 continues to rotate, the food in each sterilization chamber 6 can fully contact the steam, ensuring comprehensive and thorough sterilization.

[0041] When the sterilization process is completed, the steam needs to be discharged. At this time, the one-way blocking ball 15 in the connecting pipe 12 at one end of the exhaust pipe 3 blocks the air hole 13 under the action of the spring 17 to prevent external air from entering the sterilization chamber 6. The push column 14 in the sterilization chamber 6 will push the one-way blocking ball 15 to the side away from the exhaust pipe 3 under the action of the support net 11, so that the steam enters the connecting pipe 12 through the air hole 13 and is discharged from the exhaust pipe 3 after being filtered by the protective net 18. The protective net 18 can prevent impurities from entering the exhaust pipe 3, and can also play a certain role in buffering the steam flow. When the steam is discharged, the spring 17 will push the one-way blocking ball 15 to the air hole 13, blocking the air hole 13 again, and preparing for the next sterilization process.

[0042] For example, Figure 1 、 Figure 2 、 Figure 3 As shown, the present invention further includes a heating barrel 19 fixedly mounted on the inner wall of the bottom end of the sterilization box 1 and located directly below the pressure pipe 2 , and a heating element 20 is provided on the inner wall of the bottom end of the heating barrel 19 .

[0043] During use, after the device is started, the heating element 20 starts working. The heating element 20 converts electrical energy into thermal energy to heat the water in the heating barrel 19. As the heating progresses, the temperature of the water continues to rise. When it reaches a certain temperature, the water begins to boil and produces a large amount of high-temperature steam. These high-temperature steams will move upward due to their low density. As the steam rises, it gradually approaches the pressure pipe 2. Under the guidance of the pressure pipe 2, the steam enters the interior of the sterilization box 1, ready to sterilize the food in each sterilization cavity 6 in the sterilization cylinder 5. Through the cooperation of the heating barrel 19 and the heating element 20, high-temperature steam is continuously provided for the entire sterilization process to ensure that the temperature and pressure conditions required for sterilization are met. This design enables the equipment to generate steam quickly and stably when sterilization is required, ensuring the efficient sterilization work.

[0044] For example, Figure 1 、 Figure 2 、 Figure 3 As shown, the present invention further includes that a gas pipe 21 is fixedly connected to the middle portion of the bottom end of the heating barrel 19 .

[0045] When in use, the gas pipe 21 fixedly connected to the middle part of the bottom end of the heating barrel 19 provides a specific output channel for steam.

[0046] For example, Figure 1 、 Figure 2 、 Figure 3 As shown, the present invention further includes that the top end of the gas pipe 21 is fixedly connected to the bottom end of the outer wall of the pressure pipe 2 , and the gas pipe 21 is communicated with the pressure pipe 2 .

[0047] During use, when the equipment is started, the heating element 20 heats the water in the heating barrel 19, and the water boils to produce a large amount of high-temperature steam. The steam directly enters the pressure pipe 2 through the gas pipe 21. By connecting the gas pipe 21 and the pressure pipe 2, the flow and pressure of the steam can be better controlled to ensure that the steam enters the sterilization box 1 in a stable state, thereby improving the stability and reliability of the sterilization process. At the same time, this connection method also makes the structure of the equipment more compact, reduces the energy loss of steam during transmission, and improves energy utilization efficiency.

[0048] For example, Figure 1 、 Figure 2 、 Figure 3 As shown, the present invention further includes that a water supply pipe 22 is fixedly connected to the upper portion of one end of the heating barrel 19 away from the sterilization box 1 , and the other end of the water supply pipe 22 passes through one end of the sterilization box 1 and extends to the outside.

[0049] During use, after the equipment has been running for a period of time, if the amount of water in the heating barrel 19 is insufficient, water can be added to the heating barrel 19 through the water adding pipe 22, and the external water source flows into the heating barrel 19 through the water adding pipe 22. Under the guidance of the water adding pipe 22, the water can be accurately injected into the heating barrel 19. Since the connection position of the water adding pipe 22 and the heating barrel 19 is relatively high, interference with the heating element 20 at the bottom of the heating barrel 19 can be avoided during the water adding process, ensuring that the heating element 20 can work continuously and stably; at the same time, the design of the water adding pipe 22 passing through one end of the sterilization box 1 and extending to the outside is convenient for the operator to add water at any time during the operation of the equipment without opening the sterilization box 1, thereby ensuring the continuity and stability of the sterilization process; in addition, combined with the one-way valve arranged inside the water adding pipe 22, it can prevent the water or steam in the heating barrel 19 from flowing back through the water adding pipe 22 during the operation of the equipment, ensuring the safety and reliability of the water adding process, and providing a strong guarantee for the equipment to continuously generate steam for sterilization operations.

[0050] For example, Figure 1 、 Figure 2 、 Figure 3 As shown, the present invention further includes that the pressure pipe 2 , the exhaust pipe 3 , the gas pipe 21 and the water pipe 22 are all provided with a one-way valve.

[0051] When in use, the one-way valve in the pressure pipe 2 allows steam to flow from the heating barrel 19 or the gas pipe 21 to the sterilization cylinder 5 in the sterilization box 1, preventing steam from flowing in the opposite direction, ensuring that steam can stably enter the sterilization chamber 6 for sterilization operation, and ensuring a stable supply of steam pressure during the sterilization process;

[0052] The one-way valve in the exhaust pipe 3 allows the sterilized steam to be discharged from the sterilization chamber 6 to the outside, preventing external air from entering the sterilization box 1 during the non-discharge phase, preventing external impurities and bacteria from contaminating the sterilized food, and also helps maintain the pressure balance in the sterilization box 1;

[0053] The one-way valve in the gas pipe 21 ensures that steam can only flow from the heating barrel 19 to the pressure pipe 2, preventing the steam in the pressure pipe 2 from flowing back to the heating barrel 19, thus ensuring the unidirectionality and stability of steam delivery;

[0054] The one-way valve in the water adding pipe 22 allows water to flow from the external water source into the heating barrel 19, while preventing the water or steam in the heating barrel 19 from flowing out in the opposite direction during the operation of the equipment, thereby ensuring the safety and stability of the water adding process and providing guarantee for the continuous generation of steam;

[0055] The setting of these one-way valves ensures the one-way flow of fluid in each pipeline of the equipment, improves the reliability and safety of equipment operation, and provides strong support for the effective sterilization of food.

[0056] It should be noted that the present invention is a sterilization device for food processing, in which the food to be sterilized is placed in each sterilization chamber 6 in an orderly manner, and then the sealing door 8 is closed to ensure that the device is in a sealed state and ready for the subsequent sterilization process;

[0057] Start the heating element 20 on the inner wall of the bottom end of the heating barrel 19, which converts electrical energy into thermal energy and begins to heat the water in the heating barrel 19. At the same time, start the drive motor 9 on the outer wall of one side of the bracket 4. The output shaft of the drive motor 9 drives the drive gear 10 to rotate. Since the drive gear 10 is engaged with the gear ring 7 on the outer wall of the sterilization cylinder 5, the sterilization cylinder 5 is driven to rotate on the inner side of the bracket 4 through the bearing. As the water temperature in the heating barrel 19 increases, the water boils and produces high-temperature steam. High-temperature steam enters the sterilization chamber 1 through the pressure pipe 2. The steam first contacts the support mesh 11 in the connecting pipe 12 at one end of the pressure pipe 2. The support mesh 11 filters and stabilizes the steam flow. The steam pressure acts on the outside of the one-way blocking ball 15 and the support mesh 11 acts on the push column 14. Since the outer end of the push column 14 is a curved surface, the support mesh 11 will push the push column 14 inward, thereby pushing the one-way blocking ball 15 out of the air hole 13. At this time, the high-temperature steam can enter the sterilization chamber 6 through the air hole 13. As the sterilization cylinder 5 continues to rotate, the food in each sterilization chamber 6 is evenly heated. The high temperature of the steam destroys the proteins, enzymes, cell membranes and nucleic acids of the microorganisms, making the microorganisms inactive and achieving the purpose of sterilization. Ensure that the food in each sterilization chamber 6 can fully contact the steam to ensure the comprehensiveness and thoroughness of the sterilization.

[0058] After the sterilization is completed, the steam is ready to be discharged. At this time, the one-way blocking ball 15 in the connecting pipe 12 at one end of the exhaust pipe 3 blocks the air hole 13 under the action of the spring 17 to prevent external air from entering the sterilization chamber 6. The push column 14 in the sterilization chamber 6, under the action of the support net 11, will push the one-way blocking ball 15 to move away from the exhaust pipe 3, so that the steam enters the connecting pipe 12 through the air hole 13 and is discharged from the exhaust pipe 3 after being filtered by the protective net 18. The protective net 18 prevents impurities from entering the exhaust pipe 3 and plays a role in buffering the steam flow. When the steam is discharged, the spring 17 will push the one-way blocking ball 15 to the air hole 13, blocking the air hole 13 again, and preparing for the next sterilization process;

[0059] After the equipment has been running for a period of time, if the water level in the heating barrel 19 is insufficient, water can be added to the heating barrel 19 through the water adding pipe 22. The external water source flows into the heating barrel 19 through the water adding pipe 22. The one-way valve inside the water adding pipe 22 can prevent the water or steam in the heating barrel 19 from flowing out in the opposite direction.
