Description

Technical Field

[0001] This invention relates to the field of ice cream production technology, and more specifically, to an ice cream production sterilization equipment and a sterilization method thereof. Background Technology

[0002] Sterilization of ice cream packaging boxes is a crucial step in ensuring the quality and safety of ice cream products. Its core objective is to kill bacteria, mold, yeast, and other microorganisms adhering to the surface of the packaging boxes, preventing contamination of the ice cream and thus avoiding product spoilage or health risks to consumers. Ice cream packaging box sterilization must also balance sterilization effectiveness with the stability of the packaging material to prevent deformation, damage, or the release of harmful substances during the sterilization process. In actual production processes, packaging box sterilization is usually integrated into the pre-filling process, achieving automated continuous operation. For example, packaging boxes pass through the sterilization area sequentially via a conveyor line, and after sterilization, they directly enter the filling stage, reducing the possibility of secondary contamination. Furthermore, the parameters of the sterilization process need strict control. For instance, the intensity and duration of ultraviolet irradiation, the temperature and duration of hot air, must be precisely adjusted according to the material and size of the packaging boxes to ensure both the required microbial kill rate and the maintenance of the packaging box's appearance and structural integrity, thereby providing a safe and hygienic packaging carrier for ice cream products.

[0003] However, the sterilization devices for packaging boxes in the current ice cream production process are generally too simple, such as simple ultraviolet irradiation or simple high-temperature sterilization. This single method is difficult to effectively kill the bacteria remaining on the ice cream packaging boxes. In addition, the packaging boxes are three-dimensional during the sterilization process and need to be sterilized in an all-round way. However, the existing sterilization devices cannot turn the packaging boxes over during the sterilization process, which leads to the problem of incomplete sterilization of the packaging boxes.

[0014] A method for sterilizing ice cream production includes the following steps: S1: The packaging box is conveyed by the conveyor belt through the inside of the sterilization chamber. The electric heating rod inside the installation slot can heat the inside of the sterilization chamber, so that the inside of the sterilization chamber is in a high temperature state. When the packaging box passes through the inside of the sterilization chamber, it is sterilized at high temperature. When the packaging box reaches the flipping mechanism, it is flipped and conveyed to another sterilization chamber for sterilization on the other side. S2: When the packaging box that has passed through one of the sterilization chambers reaches the flipping mechanism, the rotation of motor one can drive the rotating shaft one to rotate, which in turn can drive the flipping frame, connecting frame, clamping frame one and clamping frame two to rotate 180 degrees, so that the packaging box can be flipped from the top of one conveyor belt and placed on the top of another conveyor belt for sterilization on the other side. S3: By controlling the rotation of motor 2, the mounting shaft 1 is driven to rotate inside the extension frame 1. Under the action of the tilting frame and the fixed sleeve, the connecting shaft is driven to swing inside the limiting ring frame 1 and the limiting ring frame 2, thereby driving the connecting shaft to swing and enabling multi-angle sterilization of the packaging boxes passing below. S4: When the first gear rotates, it drives the second gear to rotate synchronously. Under the action of the convex column and the rectangular frame, it drives the round rod and the inside of the fixed mounting cylinder to move back and forth. During the movement, it can draw the air heated by the electric heating rod inside the mounting groove into the inside of the fixed mounting cylinder, and then discharge it into the air distribution plate through the conveying pipe. Finally, it sprays the air through the nozzle onto the packaging box, thereby realizing a second high-temperature sterilization operation on the packaging box.

[0015] The present invention provides an ice cream production sterilization device and sterilization method, the beneficial effects of which include: 1. By setting up a flipping mechanism, the rotation of motor one drives the rotation of shaft one, which in turn drives the flipping frame, connecting frame, clamping frame one and clamping frame two to rotate 180 degrees. This allows the packaging box to be flipped from the top of one conveyor belt to the top of another conveyor belt for sterilization on the other side. When the packaging box reaches clamping frame two, the extension and retraction of the electric telescopic rod drives two locking blocks to move towards each other inside the slide, clamping the packaging box between the two clamping frames two, and then flipping it over. This achieves the purpose of flipping and placing the packaging box.

[0016] 2. By setting up a multi-angle sterilization mechanism, when the packaging box passes through the inside of the sterilization chamber, the rotation of motor 2 can drive the installation shaft 1 to rotate inside the extension frame 1. Under the action of the tilting frame and the fixed sleeve frame, the connecting shaft can be driven to swing inside the limiting ring frame 1 and the limiting ring frame 2. This allows the connecting shaft to swing, enabling multi-angle sterilization of the packaging box passing below. In conjunction with the high-temperature sterilization of the heating rod, the sterilization effect of the packaging box is further enhanced.

[0017] 3. By setting up a high-temperature sterilization mechanism, during the rotation of the mounting shaft one, the second shaft can be driven to rotate inside the outer frame one and the outer frame two under the action of the second pulley, the first pulley and the transmission belt. During the rotation, the gear plate one can be driven to rotate synchronously. Since the gear plate one and the gear plate two are meshed with each other, when the gear plate one rotates, it can drive the gear plate two to rotate synchronously. Then, under the action of the convex column and the rectangular frame, the round rod and the inside of the fixed mounting cylinder can be driven to move back and forth. During the movement, the air heated by the electric heating rod inside the mounting groove can be drawn into the inside of the fixed mounting cylinder, and then discharged into the inside of the air distribution plate through the conveying pipe. Finally, it is sprayed out onto the packaging box through the nozzle, thereby realizing the high-temperature sterilization operation of the packaging box again. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Reference Figures 1-8 This invention provides a technical solution: an ice cream production sterilization device, including a main frame 1, of which there are two main frames 1, which are placed symmetrically. Multiple support legs 4 are fixedly installed on the bottom surface of each main frame 1, and a sterilization chamber 3 is fixedly installed on the top surface of each main frame 1. A conveyor belt 2 is installed inside each main frame 1, and a flipping mechanism 5 is installed between the two main frames 1. Installation grooves 6 are provided on both inner walls of the sterilization chamber 3, and multiple heating rods 7 are installed inside the installation grooves 6. The sterilization chamber 3 is equipped with a multi-angle sterilization mechanism 8 and a high-temperature sterilization mechanism 9. In actual use, the ice cream to be sterilized is first placed... The packaging box to be sterilized is placed above one of the conveyor belts 2. As the conveyor belt 2 is conveyed, the packaging box passes through the interior of the sterilization chamber 3 for sterilization. After the packaging box enters the interior of the sterilization chamber 3, the electric heating rod 7 inside the mounting slot 6 heats the interior of the sterilization chamber 3, making the interior of the sterilization chamber 3 a high temperature state. As the packaging box passes through the interior of the sterilization chamber 3, it undergoes high-temperature sterilization. When the packaging box reaches the flipping mechanism 5, it is flipped by the flipping mechanism 5 and conveyed to the interior of another sterilization chamber 3 for sterilization on the other side, thereby greatly improving the sterilization effect of the packaging box. The flipping mechanism 5 includes a fixed plate 51, which is fixedly installed between two main frames 1. Multiple mounting brackets 52 are fixedly installed on the bottom surface of the fixed plate 51 for stable installation. Two uprights 58 are fixedly installed on the top surface of the fixed plate 51. A rotating shaft 59 is rotatably installed inside the uprights 58. A positioning frame 54 is fixedly installed on the top surface of the fixed plate 51. A motor 53 is fixedly installed inside the positioning frame 54. The output end of the motor 53 is fixedly connected to one end of the rotating shaft 59. A flipping frame 511 is fixedly installed on the outer surface of the rotating shaft 59. A connecting frame 541 is fixedly installed at one end of the flipping frame 511. A clamping frame 542 is fixedly installed at one end of the connecting frame 541. A sliding groove 543 is provided inside the clamping frame 542, and the sliding groove 543 is used for movable engagement. There are two locking blocks 544, and a clamping frame 546 is fixedly installed at one end of each locking block 544. An electric telescopic rod 545 is installed between the two locking blocks 544. A mounting frame 55 is fixedly installed on the top surface of the fixing plate 51. A locking groove 56 is opened inside the mounting frame 55. A gear 510 is fixedly installed on the outer surface of the rotating shaft 59. A toothed plate 57 is movably locked inside the locking groove 56. The toothed plate 57 and the gear 510 mesh with each other. Through the gear 510 and the toothed plate 57, when the motor 53 drives the rotating shaft 59 to rotate, the toothed plate 57 can move inside the locking groove 56 during the meshing of the gear 510 and the toothed plate 57, thereby ensuring the stability of the rotating shaft 59 during rotation, which can improve the stability of the packaging box during the flipping process.

[0023] During operation, when a packaged box passing through one of the sterilization chambers 3 reaches the flipping mechanism 5, the rotation of motor 53 drives the rotating shaft 59 to rotate, which in turn drives the flipping frame 511, connecting frame 541, clamping frame 542 and clamping frame 546 to rotate 180 degrees. This flips the packaged box from the top of one conveyor belt 2 to the top of another conveyor belt 2 for sterilization on the other side. When the packaged box reaches clamping frame 546, the extension and retraction of the electric telescopic rod 545 drives two locking blocks 544 to move towards each other inside the slide groove 543, clamping the packaged box between the two clamping frames 546, and then flipping it over. This achieves the purpose of flipping the packaged box, which means achieving double-sided sterilization of the packaged box and greatly improving the sterilization effect.

[0024] The multi-angle sterilization mechanism 8 includes a mounting plate 81, which is fixedly installed on the inner bottom surface of the sterilization chamber 3. An extension frame 1 82, an extension frame 2 83, and an extension frame 3 84 are fixedly installed on one side of the mounting plate 81. An installation shaft 1 87 is rotatably installed inside the extension frame 1 82. A limiting ring frame 1 85 and a limiting ring frame 2 86 are respectively fixedly installed at one end of the extension frame 2 83 and the extension frame 3 84. A connecting shaft 88 is provided inside the limiting ring frame 1 85 and the limiting ring frame 2 86. An ultraviolet lamp plate 813 is fixedly installed at one end of the connecting shaft 88, and the connecting shaft 88 is located at the limiting ring frame 1 85. Conical blocks 89 and 810 are fixedly installed on the outer surfaces of the limiting ring frame 85 and 86, respectively. The conical surface of conical block 89 is in contact with the bottom surface of the limiting ring frame 85, and the conical surface of conical block 810 is in contact with the top surface of the limiting ring frame 86. An inclined frame 811 is fixedly connected to the outer surface of the mounting shaft 87. A fixed sleeve 812 is fixedly connected to one end of the inclined frame 811. One end of the connecting shaft 88 is sleeved inside the fixed sleeve 812. A motor 814 is fixedly installed on the top surface of the sterilization chamber 3. The output end of the motor 814 is fixedly connected to one end of the mounting shaft 87. During operation, when the packaging box passes through the interior of the sterilization chamber 3, the rotation of the control motor 814 drives the mounting shaft 87 to rotate inside the extension frame 82. This, in turn, under the action of the tilting frame 811 and the fixed sleeve 812, causes the connecting shaft 88 to swing inside the limiting ring frame 85 and the limiting ring frame 86. This allows the connecting shaft 88 to swing, enabling multi-angle sterilization of the packaging box passing below. Combined with the high-temperature sterilization of the heating rod 7, this further enhances the sterilization effect of the packaging box. The set conical block 810 and conical block 89 ensure the stability of the ultraviolet lamp plate 813 during the swinging process.

[0025] The high-temperature sterilization mechanism 9 includes an external frame 1 91 and an external frame 2 92. External frame 1 91 and external frame 2 92 are respectively fixedly installed on the outer surfaces of limiting ring frame 1 85 and limiting ring frame 2 86. A rotating shaft 2 93 is rotatably installed inside external frame 1 91 and external frame 2 92. A geared disc 1 94 is fixedly installed on the outer surface of rotating shaft 2 93 located between external frame 1 91 and external frame 2 92. An installation shaft 2 98 is rotatably installed on the inner bottom surface of the sterilization chamber 3. A geared disc 2 99 is fixedly installed at the bottom end of installation shaft 2 98. Geared disc 2 99 meshes with geared disc 1 94. A fixed installation cylinder 910 is fixedly installed inside the installation groove 6. A sealing plug 911 is sealed and engaged inside the fixed installation cylinder 910. A conveying pipe 912 and an air inlet are fixedly connected to the outer surface of the fixed installation cylinder 910. A distribution plate 914 is fixedly installed on the outer surface of the tube 913 and the ultraviolet lamp plate 813. One end of the conveying pipe 912 is fixedly connected to the distribution plate 914. Multiple nozzles 915 are fixedly connected to the bottom surface of the distribution plate 914. One-way valves with opposite flow directions are installed on the outer surfaces of the air inlet pipe 913 and the conveying pipe 912, respectively. A protruding post 918 is fixedly connected to the bottom surface of the toothed disc 99. A rectangular frame 917 is provided on the outside of the protruding post 918. Round rods 916 are fixedly installed on both sides of the rectangular frame 917. The other end of the round rods 916 is fixedly installed on one side surface of the sealing plug plate 911. A pulley 95 is fixedly installed at the top of the rotating shaft 93. A pulley 96 is fixedly installed on the outer surface of the mounting shaft 87. A transmission belt 97 is sleeved between the pulley 95 and the pulley 96.

[0026] During operation, as the mounting shaft 87 rotates, it drives the rotating shaft 93 to rotate inside the outer frame 91 and outer frame 92 under the action of the pulley 96, pulley 95, and transmission belt 97. This rotation synchronously drives the gear disc 94 to rotate. Since gear disc 94 and gear disc 99 mesh with each other, the rotation of gear disc 94 drives gear disc 99 to rotate synchronously. This, in turn, drives the round rod 916 and the fixed mounting cylinder 910 to move back and forth under the action of the protruding post 918 and rectangular frame 917. During this movement, air heated by the heating rod 7 inside the mounting groove 6 is drawn into the fixed mounting cylinder 910, and then... The air is discharged through the conveying pipe 912 into the air distribution plate 914, and finally sprayed onto the packaging boxes through the nozzle 915, thereby achieving a second high-temperature sterilization of the packaging boxes and further improving the sterilization effect. As the ultraviolet lamp plate 813 swings, it can drive the air distribution plate 914 and the nozzle 915 to swing, so that the hot air sprayed by the nozzle 915 can contact the packaging boxes at multiple angles, thereby further improving the sterilization effect of the packaging boxes. Moreover, this device achieves comprehensive sterilization of packaging boxes through high-temperature sterilization, multi-angle ultraviolet sterilization, and multi-angle second high-temperature sterilization. Compared with the single sterilization device in the prior art, its sterilization effect is bound to be superior to the existing sterilization devices.

[0027] A method for sterilizing ice cream production includes the following steps: S1: The packaging box can be conveyed by the conveyor belt 2 through the inside of the sterilization box 3. The electric heating rod 7 inside the mounting slot 6 can heat the inside of the sterilization box 3, so that the inside of the sterilization box 3 is in a high temperature state. When the packaging box passes through the inside of the sterilization box 3, the high temperature sterilization operation is carried out. When the packaging box reaches the flipping mechanism 5, it is flipped by the flipping mechanism 5 and conveyed to the inside of another sterilization box 3 for the sterilization operation on the other side. S2: When the packaging box passes through one of the sterilization boxes 3 and reaches the flipping mechanism 5, the rotation of motor 1 53 can drive the rotating shaft 1 59 to rotate, which in turn can drive the flipping frame 511, connecting frame 541, clamping frame 1 542 and clamping frame 2 546 to rotate 180 degrees, so that the packaging box can be flipped from the top surface of one of the conveyor belts 2 and placed on the top surface of another conveyor belt 2 for sterilization on the other side. S3: By controlling the rotation of motor 2 814, the mounting shaft 1 87 is driven to rotate inside the extension frame 1 82, thereby driving the connecting shaft 88 to swing inside the limiting ring frame 1 85 and the limiting ring frame 2 86 under the action of the tilting frame 811 and the fixed sleeve frame 812, thereby driving the connecting shaft 88 to swing, which can realize multi-angle sterilization of the packaging box passing below. S4: When the gear disc 94 rotates, it can drive the gear disc 99 to rotate synchronously. In turn, under the action of the convex column 918 and the rectangular frame 917, it can drive the round rod 916 and the inside of the fixed mounting cylinder 910 to move back and forth. During the movement, the air heated by the electric heating rod 7 inside the mounting groove 6 can be drawn into the inside of the fixed mounting cylinder 910, and then discharged into the inside of the air distribution plate 914 through the conveying pipe 912. Finally, it is sprayed out through the nozzle 915 onto the passing packaging box, thereby realizing the high-temperature sterilization operation of the packaging box again.

[0028] Specifically, the working process or principle of this ice cream production sterilization equipment and its sterilization method is as follows: In use, the packaging box to be sterilized is first placed above one of the conveyor belts 2. As the conveyor belt 2 moves, the packaging box passes through the interior of the sterilization chamber 3 for sterilization. After the packaging box enters the sterilization chamber 3, the heating rod 7 inside the mounting slot 6 heats the interior of the sterilization chamber 3, bringing it to a high temperature. As the packaging box passes through the sterilization chamber 3, high-temperature sterilization occurs. When the packaging box reaches the flipping mechanism 5, it is flipped and conveyed to another... The sterilization process is carried out inside the sterilization chamber 3 on the other side. When the packaging box passes through one of the sterilization chambers 3 and reaches the flipping mechanism 5, the rotation of motor 53 drives the rotating shaft 59 to rotate, which in turn drives the flipping frame 511, connecting frame 541, clamping frame 542 and clamping frame 546 to rotate 180 degrees. This flips the packaging box from the top of one conveyor belt 2 and places it on top of the other conveyor belt 2 for sterilization on the other side. When the packaging box passes through the inside of the sterilization chamber 3, the rotation of motor 814 drives the mounting shaft 87 to rotate inside the extension frame 82. The movement of the connecting shaft 88, under the action of the tilting frame 811 and the fixed sleeve 812, allows it to swing within the limiting ring frame 1 85 and the limiting ring frame 2 86. This swinging motion enables multi-angle sterilization of the packaging boxes passing below, and, combined with the high-temperature sterilization of the heating rod 7, further enhances the sterilization effect. As the gear disc 1 94 rotates, it drives the gear disc 2 99 to rotate synchronously, which, under the action of the protruding column 918 and the rectangular frame 917, causes the round rod 916 and the fixed mounting cylinder 910 to move back and forth. During the process, the air heated by the electric heating rod 7 inside the mounting slot 6 is drawn into the fixed mounting cylinder 910, then discharged into the air distribution plate 914 through the delivery pipe 912, and finally sprayed onto the packaging box through the nozzle 915, thereby achieving a second high-temperature sterilization of the packaging box and further improving the sterilization effect. As the ultraviolet lamp plate 813 swings, it can drive the air distribution plate 914 and the nozzle 915 to swing, so that the hot air sprayed by the nozzle 915 can contact the packaging box at multiple angles, thereby further improving the sterilization effect of the packaging box.

[0029] It should be noted that motor 1 53 and motor 2 814 are existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
