Abstract
Description
Technical Field
[0001] This application relates to the field of food processing technology, and in particular to a food safety sterilization device. Background Technology
[0002] During food processing, sterilization is a crucial step in ensuring food safety and extending shelf life. Traditional food sterilization technologies are mainly divided into two categories: thermal sterilization and non-thermal sterilization. While thermal sterilization (such as pasteurization and high-temperature sterilization) is widely used, it has significant limitations: high temperatures easily damage the nutritional components (such as vitamins and active substances) and sensory qualities (such as color and taste) of food, especially heat-sensitive foods (such as juices, dairy products, and fresh meat). Among non-thermal sterilization technologies, irradiation sterilization has attracted attention because it does not require high temperatures and can preserve the original flavor of food. Its core principle is to use ionizing radiation such as gamma rays to destroy the DNA structure of microorganisms on food, thereby achieving sterilization.
[0003] In the existing technology, traditional food irradiation sterilization devices still have at least the following shortcomings in practical applications: In traditional devices, the food to be sterilized is mostly placed statically or simply transported, which can easily create dead zones for gamma ray irradiation due to stacking and obstruction, resulting in incomplete sterilization of some areas of the food and increasing food safety risks.
[0004] Therefore, we propose a food safety sterilization device to solve the above problems. Utility Model Content
[0005] The purpose of this application is to provide a food safety sterilization device that ensures that all parts of the food receive sufficient irradiation, eliminates sterilization dead spots, and achieves comprehensive and efficient sterilization of the food.
[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a food safety sterilization device, comprising a support frame and a radiation shielding cylinder fixedly mounted on the top of the support frame. A mesh-shaped material container is provided inside the radiation shielding cylinder. A horizontal shaft is fixedly mounted on the left outer wall of the mesh-shaped material container, with its left end rotatably penetrating through the left side wall of the radiation shielding cylinder. A second horizontal shaft is fixedly mounted on the right outer wall of the mesh-shaped material container, with its right end rotatably penetrating through the right side wall of the radiation shielding cylinder. An L-shaped seat is fixedly mounted on the right outer wall of the radiation shielding cylinder, with a motor fixedly mounted on the top of the L-shaped seat. The output shaft end of the motor is fixedly connected to the right end of the second horizontal shaft. A gamma-ray laser is positioned above the radiation shielding cylinder, with a gamma-ray emitting head fixedly connected to the bottom of the gamma-ray laser. A groove is formed on the top inner wall of the radiation shielding cylinder, with the bottom end of the gamma-ray emitting head extending into the groove.
[0007] By adopting the above technical solution, the motor drives the horizontal shaft two, which is fixedly connected to its output shaft, to rotate, thereby causing the mesh-shaped container to rotate. By using the gamma-ray laser, the gamma rays emitted by the gamma-ray emitter can pass through the mesh-shaped container and irradiate the food, achieving the effect of effective sterilization of the food.
[0008] A further feature of this application is that a U-shaped base is fixedly installed on the left outer wall of the radiation shielding cylinder, and the γ-ray laser is fixedly installed on the U-shaped base and is set at an angle.
[0009] By adopting the above technical solution, the U-shaped seat is used to support and fix the gamma-ray laser. By setting the gamma-ray laser in an inclined state, the gamma rays emitted from the gamma-ray emitting head can be fully irradiated onto the food inside the grid-shaped container.
[0010] A further feature of this application is that: positioning rings are fixedly installed on the left inner wall and the right inner wall of the radiation shielding cylinder, and guide rings are fixedly installed on the left outer wall and the right outer wall of the mesh-shaped material container, with the two guide rings rotatably installed in the corresponding positioning rings on the opposite sides.
[0011] By adopting the above technical solution, the stability of the mesh-shaped material container during rotation is guaranteed.
[0012] A further feature of this application is that the diameter of the mesh-shaped material container gradually decreases from the middle to both sides, and the outer wall of the middle part of the mesh-shaped material container slides and fits against the inner wall of the radiation shielding cylinder.
[0013] By adopting the above technical solution, it is possible to facilitate the smooth discharge of sterilized food and ensure that the food will not be discharged from the inlet or outlet during the process of the food being turned over by the mesh container.
[0014] A further feature of this application is that a feeding pipe is fixedly connected to the top center of the radiation shielding cylinder, and an upper end cap is threaded onto the top of the feeding pipe. An inlet / outlet hole is opened at the top center of the mesh-shaped material container, and the inlet / outlet hole is connected to the feeding pipe.
[0015] By adopting the above technical solution, it is easy to put food into the grid-shaped container.
[0016] A further feature of this application is that a discharge pipe is fixedly connected to the bottom center of the radiation shielding cylinder, and a lower end cap is threaded onto the bottom end of the discharge pipe.
[0017] By adopting the above technical solution, it is easy to discharge the sterilized food outside the radiation shielding cylinder.
[0018] A further provision of this application is that the inner diameters of the inlet / outlet port and the feed pipe are the same, and the inner diameters of the feed pipe and the outlet pipe are the same.
[0019] By adopting the above technical solution, the smoothness of material discharge is guaranteed.
[0020] A further feature of this application is that an indicator arrow is fixedly installed at the left end of the horizontal axis.
[0021] By adopting the above technical solution, the position of the feed hole can be easily determined.
[0022] A further feature of this application is that a bulk material assembly is provided inside the grid-shaped material container. The bulk material assembly includes a bulk material main rod and multiple bulk material support rods. The left and right ends of the bulk material main rod are fixedly connected to the left inner wall and the right inner wall of the grid-shaped material container, respectively. The multiple bulk material support rods are all fixedly installed on the bulk material main rod and are evenly distributed.
[0023] By adopting the above technical solution, the food inside the grid-shaped container can be stirred and dispersed during rotation, avoiding irradiation dead zones caused by food stacking, ensuring that each part of the food can receive sufficient gamma ray irradiation, and greatly reducing the risk of incomplete sterilization.
[0024] A further provision of this application is that the number of the bulk material assemblies is not less than two sets.
[0025] By adopting the above technical solutions, the effect of stirring and dispersing food is enhanced, ensuring comprehensive sterilization of food.
[0026] This application includes at least one of the following beneficial technical effects:
[0027] 1. This application utilizes a motor to drive the second horizontal shaft, the mesh-shaped material container, and the first horizontal shaft to rotate. During the rotation of the mesh-shaped material container, the food inside can be tumbled. At the same time, the combined action of the main material rod and the material support rod can stir and disperse the food, preventing it from piling up. Furthermore, gamma rays emitted by the gamma ray emitter pass through the hollow structure of the mesh-shaped material container and irradiate the food, ensuring that all parts of the food receive sufficient irradiation, eliminating sterilization dead spots, and achieving comprehensive and efficient sterilization of the food.
[0028] 2. This application utilizes indicator arrows to easily determine the position of the inlet and outlet holes. When the indicator arrow points upward, the inlet and outlet holes are located directly above, and the inlet and outlet holes are aligned and connected with the feeding pipe for easy feeding.

[0034] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0035] See Figure 1 , Figure 2 , Figure 3 and Figure 4This application provides a food safety sterilization device, including a support frame 1 and a radiation shielding cylinder 2 fixed to the top of the support frame 1. A mesh-shaped material container 3 is disposed inside the radiation shielding cylinder 2. A horizontal shaft 4 is fixedly installed on the left outer wall of the mesh-shaped material container 3, with its left end rotatably penetrating the left side wall of the radiation shielding cylinder 2. A second horizontal shaft 5 is fixedly installed on the right outer wall of the mesh-shaped material container 3, with its right end rotatably penetrating the right side wall of the radiation shielding cylinder 2. An L-shaped seat 6 is fixedly installed on the right outer wall of the radiation shielding cylinder 2, and a motor 7 is fixedly installed on the top of the L-shaped seat 6. The output shaft end of the motor 7 is fixedly connected to the right end of the second horizontal shaft 5. The motor 7 drives the second horizontal shaft 5, which is fixedly connected to its output shaft end, to rotate, thereby causing the mesh-shaped material container 3 to rotate. A [further details about the device are missing]. A gamma-ray laser 8 is installed, and a gamma-ray emitting head 9 is fixedly connected to the bottom of the gamma-ray laser 8. A groove 10 is opened on the top inner wall of the radiation shielding cylinder 2, and the bottom end of the gamma-ray emitting head 9 extends into the groove 10. By turning on the gamma-ray laser 8, the gamma rays emitted by the gamma-ray emitting head 9 can pass through the mesh-shaped container 3 and irradiate the food. This can directly hit the DNA molecules of microorganisms on the food, causing DNA strand breaks (single-strand or double-strand breaks) and base damage (such as base loss, oxidation, or cross-linking), causing the genetic material to break into fragments. Microorganisms cannot replicate genetic information and thus lose their ability to reproduce, thereby achieving effective sterilization. Furthermore, the use of gamma-ray irradiation for food sterilization does not require high temperature, making it suitable for the sterilization of heat-sensitive foods and preserving the original flavor and nutritional components of the food.
[0036] In this embodiment, a U-shaped base 11 is fixedly installed on the left outer wall of the radiation shielding cylinder 2. The gamma-ray laser 8 is fixedly installed on the U-shaped base 11 and is set at an angle. The design of the U-shaped base 11 serves to support and fix the gamma-ray laser 8, ensuring that the gamma-ray laser 8 is used stably. By setting the gamma-ray laser 8 to an angled state, the gamma rays emitted from the gamma-ray emitting head 9 can fully irradiate the food inside the grid-shaped container cylinder 3.
[0037] In this embodiment, positioning rings 12 are fixedly installed on the left and right inner walls of the radiation shielding cylinder 2, and guide rings 13 are fixedly installed on the left and right outer walls of the mesh-shaped material container 3. The two guide rings 13 are rotatably installed in the corresponding positioning rings 12 on the opposite sides. The cooperation between the positioning rings 12 and the guide rings 13 ensures the stability of the mesh-shaped material container 3 when it rotates.
[0038] In this embodiment, the diameter of the mesh-shaped container 3 gradually decreases from the middle to both sides. The outer wall of the middle part of the mesh-shaped container 3 slides and fits against the inner wall of the radiation shielding cylinder 2, which not only helps the sterilized food to be discharged smoothly, but also ensures that the food will not be discharged from the inlet / outlet hole 16 during the process of the mesh-shaped container 3 being turned over.
[0039] In this embodiment, the top center of the radiation shielding cylinder 2 is fixedly connected to the feeding pipe 14, and the top end of the feeding pipe 14 is threaded with an upper end cap 15. The top center of the mesh-shaped container cylinder 3 is provided with an inlet / outlet hole 16, which is connected to the feeding pipe 14 so as to put food into the mesh-shaped container cylinder 3.
[0040] In this embodiment, a discharge pipe 17 is fixedly connected to the bottom center of the radiation shielding cylinder 2. A lower end cap 18 is threaded onto the bottom end of the discharge pipe 17 to facilitate the discharge of sterilized food out of the radiation shielding cylinder 2. It should be noted that a portion of the lower end cap 18 is inserted into the discharge pipe 17, so that during the food sterilization process, some food will not fall into the discharge pipe 17.
[0041] In this embodiment, the inner diameters of the inlet / outlet hole 16 and the feed pipe 14 are the same, and the inner diameters of the feed pipe 14 and the outlet pipe 17 are the same, to ensure smooth material discharge.
[0042] In this embodiment, an indicator arrow 19 is fixedly installed on the left end of the horizontal axis 4, which can facilitate the determination of the position of the inlet hole 16, such as... Figure 2 As shown, when the indicator arrow 19 points upward, the inlet / outlet hole 16 is located directly above, and the inlet / outlet hole 16 is aligned and connected with the feeding pipe 14 for easy feeding; when the indicator arrow 19 points downward, the inlet / outlet hole 16 is located directly below, and the inlet / outlet hole 16 is aligned and connected with the discharge pipe 17 for easy discharge.
[0043] In this embodiment, a material dispersing assembly is provided inside the mesh-shaped material container 3. The number of material dispersing assemblies is not less than two sets. The material dispersing assembly includes a main material dispersing rod 20 and multiple material dispersing support rods 21. The left and right ends of the main material dispersing rod 20 are fixedly connected to the left inner wall and the right inner wall of the mesh-shaped material container 3, respectively. The multiple material dispersing support rods 21 are all fixedly installed on the main material dispersing rod 20 and are evenly distributed. The material dispersing assembly composed of the main material dispersing rod 20 and multiple material dispersing support rods 21 rotates synchronously with the mesh-shaped material container 3, which can stir and disperse the food, avoid the irradiation dead corners caused by food stacking, ensure that each part of the food can receive sufficient γ-ray irradiation, and greatly reduce the risk of incomplete sterilization.
[0044] In this embodiment, it should be noted that the radiation shielding cylinder 2 is made of an outer lead cylinder layer and an inner stainless steel layer. The feeding pipe 14, the upper end cover 15, the discharge pipe 17, and the lower end cover 18 are made of the same material as the radiation shielding cylinder 2. Therefore, during the food sterilization process, it can be ensured that the emitted γ-rays will not cause damage to the workers' bodies. The motor 7 and the γ-ray laser 8 can be purchased on the market or customized in the factory. Their circuit connection and controllability are mature technologies in the field and have been fully disclosed. Therefore, they will not be described in detail here.
[0045] With the above structure, when the food safety sterilization device provided in this application is used, firstly, the motor 7 is controlled to run, which drives the second horizontal shaft 5, the mesh-shaped material container 3 and the first horizontal shaft 4 to rotate. The indicator arrow 19 follows the rotation of the first horizontal shaft 4. When the indicator arrow 19 points vertically upward, the motor 7 stops running. At this time, the inlet and outlet hole 16 is located directly above, and the inlet and outlet hole 16 is aligned and connected with the feeding pipe 14. Then, the upper end cap 15 at the top of the feeding pipe 14 is unscrewed, and the food to be sterilized is put into the mesh-shaped material container 3 through the feeding pipe 14 and the inlet and outlet hole 16. After the feeding is completed, the upper end cap 15 is tightened to ensure the sealing of the inside of the radiation shielding cylinder 2.
[0046] Next, the motor 7 and the gamma-ray laser 8 are started. The output shaft of the motor 7 drives the horizontal shaft 5 to rotate, which in turn drives the mesh-shaped material container 3 to rotate. During this process, the cooperation between the positioning ring 12 and the guide ring 13 ensures the stability of the rotation of the mesh-shaped material container 3. During the rotation of the mesh-shaped material container 3, the food inside it tumbles. At the same time, the synergistic effect of the bulk material main rod 20 and the bulk material support rod 21 plays a role in stirring and dispersing the food, preventing the food from piling up.
[0047] At the same time, the gamma-ray laser 8 emits gamma rays through the gamma-ray emitting head 9. The gamma rays pass through the hollow structure of the mesh-shaped material container 3 and irradiate the food. The gamma rays directly destroy the DNA molecules of microorganisms on the food, causing them to lose their ability to reproduce, thereby achieving effective sterilization. Because the mesh-shaped material container 3 rotates continuously and the rays cover at an angle, coupled with the comprehensive stirring and dispersing effect of the main material rod 20 and the material support rod 21 on the food, it can be ensured that all parts of the food can receive sufficient irradiation, eliminating sterilization dead corners and achieving comprehensive and efficient sterilization of the food.
[0048] After the food has been sterilized for a certain period of time, the gamma-ray laser 8 is turned off. When the indicator arrow 19 rotates to a vertical position, the motor 7 is stopped. At this time, the inlet / outlet hole 16 is aligned and connected with the outlet pipe 17. The lower end cover 18 is unscrewed, and the sterilized food falls into the outlet pipe 17 through the inlet / outlet hole 16 under the action of gravity. Finally, it is discharged from the bottom of the outlet pipe 17, thus completing the entire sterilization process.
