Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically a three-dimensional dynamic ultraviolet sterilization device for food processing. Background Technology

[0002] Food processing technology is a comprehensive branch that transforms raw materials into edible products through a series of industrial processes, involving the application of physical, chemical, and biological methods to ensure food safety, quality, and shelf life. This field includes processes such as cleaning, cutting, heating, cooling, sterilization, and packaging. Among these, a three-dimensional dynamic ultraviolet sterilization device for food processing refers to a device that uses ultraviolet radiation technology and is specifically designed for efficient and comprehensive sterilization of food surfaces during food processing.

[0003] Existing ultraviolet (UV) sterilization devices typically employ a static design, with UV lamps fixed to the inner wall of the chamber. This limits the direction and range of irradiation, preventing adaptive adjustments to cover all food surfaces. The fixed position of food after placement creates shadows on uneven areas or edges, resulting in blind spots and a higher risk of microbial residue. This limitation is particularly pronounced when processing irregularly shaped or large foods, such as fruit and vegetable pieces or meat products, where certain surfaces cannot be effectively exposed to UV light. Manual turning or repeated processing is required, increasing labor intensity and time costs, and slowing down production. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a three-dimensional dynamic ultraviolet sterilization device for food processing, which solves the problem that existing ultraviolet sterilization devices typically adopt a static design, with the ultraviolet lamp fixedly installed on the inner wall of the chamber, limiting the irradiation direction and range, and failing to adaptively adjust to cover all surfaces of the food.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a three-dimensional dynamic ultraviolet sterilization device for food processing, comprising a housing, a connecting plate fixedly connected to one side of the housing, a door rotatably connected inside the connecting plate, ultraviolet sterilization lamps fixedly connected to the inner walls of the housing and the door, a first motor fixedly connected to the lower surface of the housing, a drive shaft fixedly connected to the output end of the first motor, a mounting bracket fixedly connected to the upper surface of the drive shaft, rotating holes on both sides of the mounting bracket, a first rotating shaft fixedly connected to the inner wall of the rotating holes, a placement frame fixedly connected to the outer wall of the first rotating shaft, a second motor fixedly connected to the outer wall of the mounting bracket, and the first rotating shaft fixedly connected to the output end of the second motor.

[0006] As a preferred embodiment of this utility model, a connecting block is fixedly connected to the upper surface of the placement frame, a second rotating shaft is fixedly connected to the outer wall of the connecting block, and a cover is fixedly connected to the outer wall of the second rotating shaft.

[0007] As a preferred embodiment of this utility model, the outer walls of both the placement frame and the cover are provided with multiple perforations.

[0008] As a preferred technical solution of this utility model, the upper surface of the cover is provided with screw holes on both sides, and the inner wall of the screw holes is threaded with self-tightening screws.

[0009] As a preferred embodiment of this utility model, a slot is provided on one side of the box body, a buckle is fixedly connected inside the door body, the buckle is engaged with the inner wall of the slot, and a handle is fixedly connected to the outer wall of the door body.

[0010] As a preferred embodiment of this utility model, a bracket is fixedly connected to the lower surface of the box.

[0011] As a preferred technical solution of this utility model, the screw hole extends through the cover and into the interior of the placement frame.

[0012] In summary, this application includes at least one of the following beneficial technical effects: 1. This three-dimensional dynamic ultraviolet sterilization device for food processing, through the coordinated drive of a motor, drives the mounting frame to rotate via a transmission shaft. Simultaneously, a second motor, through a rotating shaft, causes the placement frame to rotate in an additional dimension. This causes the food to perform multi-directional, continuous three-dimensional dynamic movement during the sterilization process. This movement mechanism ensures that ultraviolet radiation evenly covers the food surface from all angles, eliminating blind spots and significantly improving the comprehensiveness and thoroughness of sterilization. Dynamic exposure optimizes the distribution of ultraviolet energy, reduces processing time, improves overall efficiency, and avoids local over- or under-irradiation, maintaining the original nutritional components and sensory quality of the food. Automated rotation reduces the need for manual intervention, enhances the continuity and reliability of the operation process, reduces energy consumption, and extends the service life of the equipment.

[0013] 2. This three-dimensional dynamic ultraviolet sterilization device for food processing features an openable and closable cover structure with a rotating shaft connection for smooth opening and closing, facilitating food loading and unloading, reducing operational interruption time, and improving process continuity. Perforations distributed on the placement frame and cover surface allow ultraviolet light to penetrate from multiple directions, enhancing irradiation coverage, eliminating potential blind spots, and ensuring uniform and thorough sterilization. Self-tightening screws provide quick fixing and unlocking functions through threaded connections, simplifying the sealing process of the cover and improving operational convenience and reliability. The cooperation of the slot and buckle allows the door to be tightly locked, enhancing sealing, effectively preventing ultraviolet leakage, ensuring operational safety, and the bracket supports the overall structure, increasing stability, reducing vibration during equipment operation, and extending service life.

Detailed Implementation

[0016] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0017] Please see Figure 1-4 In this embodiment: a three-dimensional dynamic ultraviolet sterilization device for food processing includes a housing 1, a connecting plate 2 fixedly connected to one side of the housing 1, a door 3 rotatably connected inside the connecting plate 2, ultraviolet sterilization lamps 4 fixedly connected to the inner wall of the housing 1 and the inner wall of the door 3, a first motor 5 fixedly connected to the lower surface of the housing 1, a drive shaft fixedly connected to the output end of the first motor 5, a mounting bracket 6 fixedly connected to the upper surface of the drive shaft, rotating holes 7 on both sides of the mounting bracket 6, a first rotating shaft 8 fixedly connected to the inner wall of the rotating holes 7, a placement frame 9 fixedly connected to the outer wall of the first rotating shaft 8, a second motor 10 fixedly connected to the outer wall of the mounting bracket 6, and the first rotating shaft 8 fixedly connected to the output end of the second motor 10.

[0018] In this embodiment, through the coordinated drive of the motor, the transmission shaft drives the mounting frame 6 to rotate, while the second motor 10 causes the placement frame 9 to rotate in an additional dimension via the rotating shaft. This causes the food to perform multi-directional, continuous three-dimensional dynamic movement during the sterilization process. This movement mechanism ensures that ultraviolet radiation evenly covers the food surface from all angles, eliminating blind spots and significantly improving the comprehensiveness and thoroughness of sterilization. Dynamic exposure optimizes the distribution of ultraviolet energy, reduces processing time, improves overall efficiency, and avoids local over-irradiation or under-irradiation, maintaining the original nutritional components and sensory quality of the food. Automated rotation reduces the need for manual intervention, enhances the continuity and reliability of the operation process, and reduces energy consumption while extending the service life of the equipment.

[0019] Preferably, a connecting block 11 is fixedly connected to the upper surface of the placement frame 9, a second rotating shaft 12 is fixedly connected to the outer wall of the connecting block 11, and a cover 13 is fixedly connected to the outer wall of the second rotating shaft 12.

[0020] Among them, the openable and closable cover 13 structure and the rotating shaft connection enable smooth opening and closing actions, which facilitates food loading and unloading, reduces operation interruption time, and improves process continuity.

[0021] Preferably, both the outer walls of the placement frame 9 and the cover 13 are provided with multiple perforations 14.

[0022] The perforations 14 are distributed on the surface of the placement frame 9 and the cover 13, allowing ultraviolet rays to penetrate from multiple directions, enhancing the irradiation coverage, eliminating potential blind spots, and ensuring uniform and thorough sterilization.

[0023] Furthermore, screw holes 15 are provided on both sides of the upper surface of the cover 13, and self-tightening screws 16 are threaded into the inner wall of the screw holes 15. The screw holes 15 penetrate the cover 13 and extend into the interior of the placement frame 9.

[0024] The self-tightening screw 16 provides quick fixing and unlocking functions through threaded connection, simplifying the sealing process of the cover 13 and improving the ease of operation and reliability.

[0025] Furthermore, a slot 17 is provided on one side of the box body 1, and a buckle 18 is fixedly connected inside the door body 3. The buckle 18 is engaged with the inner wall of the slot 17, and a handle 19 is fixedly connected to the outer wall of the door body 3.

[0026] The combination of the slot 17 and the buckle 18 allows the door 3 to be tightly engaged, enhancing its sealing performance, effectively preventing ultraviolet leakage, and ensuring operational safety.

[0027] Preferably, a bracket 20 is fixedly connected to the lower surface of the housing 1.

[0028] Among them, the bracket 20 supports the overall structure, increases stability, reduces vibration during equipment operation, and extends service life.

[0029] The working principle and usage process of this utility model are as follows: By combining mechanical transmission with ultraviolet radiation, dynamic sterilization of food is achieved from multiple angles without blind spots. After the equipment is started, the first motor 5 located below the chamber 1 drives the transmission shaft to rotate, and the transmission shaft drives the mounting frame 6 on its top to revolve horizontally. At the same time, the second motor 10 fixed on the mounting frame 6 starts, driving the first rotating shaft 8, causing the placement frame 9 to rotate around its own axis. The combined motion of revolution and rotation causes the food placed in the frame to undergo complex three-dimensional dynamic tumbling, completely changing its spatial posture. During this process, multiple ultraviolet germicidal lamps 4 fixed to the inner wall of the chamber 1 and the inner wall of the door 3 continuously emit ultraviolet light of a specific wavelength. The perforations 14 throughout the placement frame 9 and its top cover ensure that ultraviolet light can fully penetrate from all directions and irradiate every surface of the food. This dynamic exposure mode completely eliminates the shadows and blind spots under static irradiation, causing the DNA or RNA structure in microbial cells to be inactivated by absorbing ultraviolet light, thereby achieving efficient and uniform sterilization. The housing 1 and the door 3 are tightly closed by the buckle 18 and the slot 17 to form a closed cavity, which effectively prevents ultraviolet leakage and ensures operational safety.

[0030] Operating Procedures: Preparation: Confirm the power connection is normal and that the bracket 20 firmly supports the housing 1. Check the inner wall of housing 1 and the UV lamps inside the door 3 for damage. Clean and disinfect the placement frame 9 and lid 13 before use to ensure hygiene. Load food, pull the handle 19 on the door 3 outwards to release the internal latch 18 from the slot 17 of housing 1, and open the door 3. Place the food to be sterilized evenly into the placement frame 9, ensuring the stack is not too thick to allow effective UV light penetration. Rotate the lid 13 to close via the second pivot 12, covering the placement frame 9. Manually screw in the self-tightening screw 16, allowing its threaded end to pass through the screw hole 15 of the lid 13 and into the placement frame 9, thus securing the lid 13 and placement frame 9 together to prevent accidental opening or material spillage during operation. Closing and Setting. Close door 3, ensuring the latches 18 on door 3 are accurately engaged in the slots 17 on the side of cabinet 1. A crisp click indicates the door is completely sealed. Based on the type of food to be sterilized, the initial bacterial count, and process requirements, set appropriate sterilization time, motor speed, and other operating parameters on the equipment control panel. Start the machine, confirming the parameters are correct and door 3 is tightly closed, then start the equipment. The first motor 5 and the second motor 10 begin working collaboratively according to the set program, driving the placement frame 9 in three-dimensional dynamic motion. The ultraviolet lamps inside the cabinet simultaneously illuminate, providing all-around sterilization of the continuously tumbling food. Operators should stay away from the equipment's observation window and avoid direct contact with the ultraviolet light source. After the running time is complete, the equipment automatically stops, the motors stop, and the ultraviolet lamps turn off. Wait a moment for the equipment to completely stop before opening door 3. Loosen and remove the self-tightening screws 16, open the cover 13, and remove the sterilized food. Transfer the food to the next processing step or package it.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
