Description

Technical Field

[0001] This utility model relates to the field of sterilization equipment technology, specifically a sterilization device for food production. Background Technology

[0002] In the food production industry, sterilization is a crucial step in ensuring food quality and safety and extending shelf life. Sterilization equipment, as the core device for this process, directly impacts food production efficiency and safety standards. With the increasing scale of the food industry, the market demands higher levels of automation, sterilization uniformity, ease of cleaning, and energy efficiency from sterilization equipment.

[0003] Currently, the sterilization equipment commonly used in food production on the market has the following shortcomings: First, the sterilization methods are relatively simple, with most equipment relying solely on fixed-position sterilization lamps or high-temperature hot air for sterilization. This fixed sterilization mode easily leads to incomplete sterilization of certain areas of food, and some areas may experience deterioration in taste and nutrient loss due to prolonged exposure to high-intensity sterilization (such as continuous high temperature or strong light), making it difficult to meet the differentiated needs of different types of food for sterilization intensity and uniformity. Second, the power system design of the equipment is relatively decentralized, usually requiring separate drive motors for the conveying device, sterilization mechanism, and cleaning device. Multi-motor drive not only increases the manufacturing cost and energy consumption of the equipment, but may also lead to mismatches in conveying speed, sterilization efficiency, and cleaning frequency due to asynchronous operation of each motor, affecting the stability of the overall production process, and also increasing the difficulty and cost of later equipment maintenance. Third, the cleaning problem of the conveyor belt has not been effectively solved. During food transportation, residues and debris easily adhere to the conveyor belt. If not cleaned promptly, this can not only breed bacteria, leading to secondary contamination of subsequently transported food, but also affect the transmission stability of the conveyor belt and shorten the equipment's lifespan. Existing equipment often requires regular manual cleaning of the conveyor belt, which not only increases labor costs but may also leave food safety hazards due to untimely or incomplete cleaning.

[0021] Example 1 Reference Figure 1-5This is the first embodiment of the present utility model, which adopts the following technical solution, including a conveying device 2 and a sterilization box 1 fixedly installed on the top of the conveying device 2 for sterilization. A fixed frame 3 is fixedly installed on the front side of the conveying device 2. A drive shaft 5 is rotatably installed inside the fixed frame 3. A drive motor 4 is fixedly connected to the left side of the fixed frame 3. The output end of the drive motor 4 is fixedly installed with the drive shaft 5. It also includes a cleaning component set on the right side of the conveying device 2 for cleaning the conveyor belt. The sterilization mechanism is located inside the sterilization chamber 1 and is used to sterilize the food on top of the conveying device 2; The sterilization drive assembly is located on the top of the fixed frame 3 and is used to transmit the power of the drive motor 4 to the sterilization mechanism to make it rotate. The cleaning drive mechanism is located on the side of the fixed frame 3 away from the drive motor 4 and is used to drive the cleaning assembly. The cleaning assembly includes a sixth bevel tooth 7, a cleaning shaft 71 and a shaft frame 72. The shaft frame 72 is fixedly installed on the front and rear sides of the left side of the conveying device 2. The cleaning shaft 71 is rotatably installed inside the shaft frame 72. The sixth bevel tooth 7 is fixedly connected to the end of the cleaning shaft 71 near the drive shaft 5.

[0022] Specifically, the sixth bevel tooth 7 can be driven to rotate by the fifth bevel tooth 56, and the sixth bevel tooth 7 can drive the cleaning shaft 71 to rotate. When the cleaning shaft 71 rotates, the shaft frame 72 can ensure the rotation is stable. The rotation of the cleaning shaft 71 can clean the surface of the conveyor belt of the conveying device 2, ensuring that there are no residues on the surface of the conveyor belt after sterilization, and avoiding affecting the next conveying and sterilization operation.

[0023] Example 2 The second embodiment of this utility model adopts the following technical solution: the sterilization mechanism includes a sterilization lamp 8, a ventilation frame 81, a fan 82, and an electric heating wire 83. The sterilization lamp 8 is disposed inside the sterilization chamber 1. The ventilation frame 81 is fixedly connected to both sides of the sterilization lamp 8. The fan 82 is fixedly connected to the bottom of the ventilation frame 81. The electric heating wire 83 is fixedly connected to the top of the ventilation frame 81. The sterilization drive assembly includes a first bevel gear 51, a second bevel gear 52, a driven shaft 6, a synchronization gear 61, a synchronization belt 62, a screw 63, and a second synchronization gear 65. The bottom of the screw 63 passes through the second synchronization gear 65 and the sterilization chamber 1 from top to bottom and is fixedly connected to the top of the sterilization lamp 8. A keyway is provided on one side of the screw 63. The second synchronization gear 65 and the interior of the sterilization chamber 1 are longitudinally slidably engaged with the screw 63 through the keyway. The second synchronization gear 65 is longitudinally slidably mounted on the surface of the screw 63 through the keyway and is located at the top of the sterilization chamber 1. The driven shaft 6 is rotatably mounted on the top of the fixed frame 3. The synchronous gear 61 is fixedly mounted on the top of the driven shaft 6. The second bevel gear 52 is fixedly mounted on the bottom of the surface of the driven shaft 6 and meshes with the first bevel gear 51. The first bevel gear 51 is fixedly connected to the side of the drive shaft 5 near the drive motor 4. The synchronous belt 62 is sleeved on the surface of the synchronous gear 61. The synchronous gear 61 is connected to the synchronous gear 65 through the synchronous belt 62. The cleaning drive mechanism includes a third bevel gear 53, a fourth bevel gear 54, a driven shaft 55, and a fifth bevel gear 56. The third bevel gear 53 is fixedly connected to the end of the drive shaft 5 away from the drive motor 4. The driven shaft 55 is rotatably mounted on the side of the fixed frame 3 away from the drive motor 4. The fourth bevel gear 54 is fixedly connected to the top of the driven shaft 55 and meshes with the third bevel gear 53. The fifth bevel gear 56 is fixedly connected to the bottom of the driven shaft 55 and meshes with the sixth bevel gear 7.

[0024] Specifically, the germicidal lamp 8 is driven to rotate by the screw 63. When the germicidal lamp 8 rotates, it can perform sterilization over a large area evenly, avoiding sterilization at a single fixed point. At the same time, the rotation of the germicidal lamp 8 drives the ventilation rack 81 and the fan 82 to rotate, and the rotating parts will perform high-temperature sterilization, avoiding sterilization at a single location and preventing the food from being affected by excessively high local temperature. The electric heating wire 83 can heat the air blown by the fan 82 to achieve high-temperature sterilization. The drive motor 4 can drive the drive shaft 5 to rotate, and then the drive shaft 5 drives the first bevel gear 51 fixed to it to rotate. The first bevel gear 51 then drives the second bevel gear 52 meshing with it to rotate. After the second bevel gear 52 rotates, it drives the driven shaft 6 fixed to it to rotate. The driven shaft 6 drives the synchronous gear 61 to rotate, and then the synchronous belt 62 drives the synchronous gear 61 to rotate. The rotation of the second 65 is driven by the keyway transmission between the second 65 and the screw 63. The rotation of the second 65 drives the screw 63 to rotate, which in turn drives the germicidal lamp 8 fixed to it to rotate, achieving a rotational sterilization effect. The drive shaft 5 is driven to rotate by the drive motor 4, which in turn drives the third bevel gear 53 to rotate. The third bevel gear 53 drives the fourth bevel gear 54, which meshes with it, to rotate. Then, the lateral power output is converted into longitudinal power transmission, which drives the driven shaft 55, which is fixed to the fourth bevel gear 54, to rotate. The driven shaft 55 drives the fifth bevel gear 56 to rotate, which causes the sixth bevel gear 7, which meshes with the fifth bevel gear 56, to rotate synchronously. This causes the sixth bevel gear 7 to drive the cleaning shaft 71 to rotate, achieving a cleaning effect. At this time, the synchronous rotation of the first bevel gear 51 and the third bevel gear 53 can drive the sterilization mechanism and the cleaning component to operate synchronously.

[0025] Example 3 In the third embodiment of this utility model, the following technical solution is adopted: the surface of the screw 63 is threaded with an adjusting nut 64, the bottom of the adjusting nut 64 is located at the top of the synchronous gear 65, the adjusting nut 64 is used to adjust the sterilization height of the sterilizing lamp 8, and several sets of sealing curtains 11 are fixedly connected to both sides of the sterilization box 1 for sealing the sterilizing hot air inside the sterilization box 1.

[0026] Specifically, the rotation height of the screw 63 can be adjusted by connecting the adjusting nut 64 to the screw 63 via a threaded connection. When the adjusting nut 64 is rotated, the position of the adjusting nut 64 on the screw 63 changes, which in turn changes the rotation height of the sterilization lamp 8, achieving the effect of adjusting the sterilization height according to the food sterilization requirements. The sealing curtain 11 facilitates the entry of food into the sterilization chamber 1, while also preventing the hot air inside the sterilization chamber 1 from dissipating, thus ensuring a stable sterilization temperature inside the sterilization chamber 1.

[0027] Working principle: The core power source of the equipment is the drive motor 4, which is fixedly installed on the left side of the fixed frame 3 in front of the conveying device 2. When the equipment is started, the drive motor 4 outputs power, which drives the drive shaft 5, which is fixedly connected to it, to rotate stably inside the fixed frame 3. The drive shaft 5 serves as the core of power distribution. Through different transmission components fixed on the surface, the power is transmitted to the sterilization drive assembly and the cleaning drive mechanism respectively, ensuring the synchronous operation of each mechanism. When the drive shaft 5 rotates, it drives the first bevel tooth 51 on the side of its surface closest to the drive motor 4 to rotate synchronously; the first bevel tooth 51 drives the second bevel tooth 52 that it meshes with through gear meshing; the second bevel tooth 52 is fixed to the bottom of the surface of the driven shaft 6, thereby driving the driven shaft 6 to rotate on the top of the fixed frame 3; the synchronous tooth 61 fixed on the top of the driven shaft 6 rotates with the shaft, and transmits power to the synchronous tooth 65 on the top of the sterilization box 1 through the synchronous belt 62 sleeved on its surface, so that the synchronous tooth 65 rotates synchronously. Synchronous gear 65 forms a longitudinal sliding fit and transmission connection with screw 63 through a keyway. Therefore, when synchronous gear 65 rotates, it will drive screw 63 to rotate. The bottom of screw 63 passes through sterilization box 1 and is fixed to the top of sterilization lamp 8, thereby driving sterilization lamp 8 to rotate inside sterilization box 1, realizing uniform sterilization in multiple angles and over a large area, avoiding sterilization dead corners and local damage to food caused by fixed sterilization. As the sterilization lamp 8 rotates, the ventilation racks 81 fixed on both sides of it also rotate. The fan 82 fixed at the bottom of the ventilation rack 81 rotates synchronously, and the electric heating wire 83 at the top of the ventilation rack 81 generates heat after being energized. The fan 82 converts the heat generated by the electric heating wire 83 into high-temperature hot air, which is then blown evenly onto the food on the conveyor device 2 as the ventilation rack 81 rotates, forming a dual sterilization mode of "ultraviolet light + high-temperature hot air" to further enhance the sterilization effect. The screw 63 is threaded with an adjusting nut 64, and the bottom of the adjusting nut 64 is located at the top of the second synchronous tooth 65. When it is necessary to adjust the position of the sterilizing lamp 8 according to the height of the food, the adjusting nut 64 is rotated, and the adjusting nut 64 is longitudinally displaced on the screw 63. By squeezing or releasing the second synchronous tooth 65, the screw 63 is driven to move longitudinally as a whole, so as to achieve flexible adjustment of the sterilization height of the sterilizing lamp 8 and meet the sterilization needs of foods of different thicknesses. A third bevel tooth 53 is fixed at the end of the drive shaft 5 away from the drive motor 4. When the drive shaft 5 rotates, it drives the third bevel tooth 53 to rotate synchronously. The third bevel tooth 53 drives the fourth bevel tooth 54 that it is engaged with to rotate through gear meshing. This process realizes the power transfer from the transverse drive shaft 5 direction to the longitudinal driven shaft 2 55 direction. The fourth bevel tooth 54 is fixed at the top of the driven shaft 2 55, thereby driving the driven shaft 2 55 to rotate longitudinally on the side of the fixed frame 3 away from the drive motor 4. The fifth bevel tooth 56 fixed at the bottom of the driven shaft 2 55 rotates with the shaft and drives the sixth bevel tooth 7 that it is engaged with to rotate through gear meshing. The sixth bevel tooth 7 is fixed at one end of the cleaning shaft 71 near the drive shaft 5. The cleaning shaft 71 is rotatably installed inside the shaft brackets 72 on the front and rear sides of the left side of the conveyor device 2. The shaft brackets 72 ensure the stable rotation of the cleaning shaft 71. When the sixth bevel tooth 7 rotates, it drives the cleaning shaft 71 to rotate synchronously. During the rotation, the cleaning shaft 71 scrapes or sweeps the surface of the conveyor belt of the conveyor device 2 to remove food residues and debris on the conveyor belt in a timely manner, avoid secondary pollution, and ensure smooth transmission of the conveyor belt. Several sets of sealing curtains 11 are fixedly connected to both sides of the sterilization chamber 1. When food enters or leaves the sterilization chamber 1 with the conveyor device 2, the sealing curtains 11 can be opened and closed flexibly with the push of the food to facilitate the entry and exit of the food. After the food enters the sterilization chamber 1, the sealing curtains 11 can automatically reset and seal the openings on both sides of the sterilization chamber 1, effectively preventing the leakage of hot air for high-temperature sterilization inside the chamber, ensuring the stability of the internal temperature of the sterilization chamber 1, reducing energy waste, and at the same time preventing external impurities from entering the chamber and affecting the sterilization effect.
