Description

Technical Field

[0001] This utility model relates to the field of lotus root powder sterilization technology, specifically to an ozone sterilization device for fresh lotus root powder. Background Technology

[0002] Fresh lotus root powder, as a nutritious natural food ingredient, is highly favored by the market due to its delicate taste and health benefits. In the production process of fresh lotus root powder, sterilization is a key step to ensure product quality and extend shelf life. Among them, ozone sterilization is widely used in the food processing field because of its advantages such as high efficiency, no residue, and easy decomposition. However, fresh lotus root powder contains moisture during processing, and it is prone to clumping during static storage or transportation. Existing ozone sterilization devices mostly use static stacking or simple transportation methods, which are difficult to effectively deal with the clumping problem. The lotus root powder particles inside the clumping cannot fully contact the ozone, resulting in incomplete sterilization and local microbial contamination. At the same time, clumping can also cause conveyor blockage, affecting production continuity, increasing equipment maintenance costs, and restricting the efficiency and quality stability of industrial production of fresh lotus root powder.

This invention features a novel structure, combining a crushing and cutting structure with an airflow dispersion structure. The crushing and cutting structure breaks large clumps into small particles, while the airflow dispersion structure further disperses the particles and prevents secondary clumping, keeping the lotus root powder in a loose state. This ensures sufficient contact with ozone during sterilization, significantly improving the uniformity and thoroughness of sterilization and effectively reducing the risk of localized microbial contamination.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a fresh lotus root powder ozone sterilization device, comprising a sterilization box, two support plates fixedly connected to the upper side of the sterilization box, an mounting plate fixedly connected to the upper side of the two support plates, a crushing hopper fixedly connected to the upper side of the mounting plate, a crushing mechanism provided on one side of the crushing hopper, a conical shell provided on the upper side of the sterilization box, a conveying pipe fixedly connected to the lower end of the conical shell, and a sterilization mechanism provided inside the sterilization box.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Please refer to Figures 1 to 5This utility model provides a technical solution: an ozone sterilization device for fresh lotus root powder, including a sterilization box 1. Two support plates 2 are fixedly connected to the upper side of the sterilization box 1. An mounting plate 3 is fixedly connected to the upper side of the two support plates 2. A crushing hopper 4 is fixedly connected to the upper side of the mounting plate 3. A crushing mechanism 5 is provided on one side of the crushing hopper 4. A conical shell 6 is provided on the upper side of the sterilization box 1. A conveying pipe 7 is fixedly connected to the lower end of the conical shell 6. A sterilization mechanism 8 is provided inside the sterilization box 1. An air pump 9 is installed on the upper side of the mounting plate 3. A ring pipe 10 is fixedly connected to the outer side of the lower end of the feeding pipe 58. A connecting pipe 11 is provided between the output end of the air pump 9 and the ring pipe 10. Multiple jet nozzles 12 that cooperate with the feeding pipe 58 are installed on the lower side of the ring pipe 10. The lower end of the jet nozzle 12 is inclined towards the lower end of the feeding pipe 58. The two ends of the connecting pipe 11 are fixedly connected to the output end of the air pump 9 and the upper side of the ring pipe 10, respectively. A pressure balancing valve 13 is installed on the upper side of the sterilization chamber 1. Fresh lotus root powder first enters the crushing hopper 4. The drive motor 51 on the mounting plate 3 starts, driving the crushing and cutting roller 52 to rotate. Through the meshing of the drive gear 54 and the driven gear 55, the cooperating cutting roller 53 rotates synchronously in opposite directions. The two cooperate to cut and crush the clumps of lotus root powder, breaking up large clumps into small particles. The crushed lotus root powder falls into the inclined collection shell 56 and is guided to the discharge pipe 58 through the conveying shell 57. At this time, the air pump 9 starts and delivers compressed air to the ring pipe 10 through the connecting pipe 11. Multiple jet nozzles 12 on the lower side of the ring pipe 10 (inclined towards the lower end of the discharge pipe 58) spray airflow to further disperse the falling lotus root powder and prevent secondary clumping. At the same time, the pressure balancing valve 13 on the upper side of the sterilization chamber 1 can adjust the air pressure inside the chamber to ensure stable airflow. In this stage, through the dual action of mechanical crushing and airflow dispersion, the lotus root powder is made into a loose state before entering the subsequent stages, improving the uniformity of sterilization.

[0018] In this embodiment, the crushing mechanism 5 includes a drive motor 51 mounted on the upper side of the mounting plate 3. A crushing and cutting roller 52 is rotatably fitted on one side of the inner wall of the crushing hopper 4, and a cooperating cutting roller 53 is rotatably fitted on the other side of the inner wall of the crushing hopper 4. One end of the crushing and cutting roller 52 extends to the outer side of the crushing hopper 4 and is fixedly connected to a drive gear 54. One end of the cooperating cutting roller 53 extends to the outer side of the crushing hopper 4 and is fixedly connected to a driven gear 55 that meshes with the drive gear 54. An inclined collecting shell 56 is fixedly connected to the lower side of the crushing hopper 4. A conveying shell 57 is fixedly connected to one side of the inclined collecting shell 56, and a feeding pipe 58 is fixedly connected to the lower side of the conveying shell 57. The crushing and cutting roller 52 and the cooperating cutting roller 53 cooperate with each other. The output end of the drive motor 51 is fixedly connected to one end of the crushing and cutting roller 52, and the lower end of the feeding pipe 58 extends into the interior of the conical shell 6. In the crushing mechanism 5, the drive motor 51 continuously drives the crushing and cutting roller 52 and the cooperating cutting roller 53 to rotate. Through the interlocking shearing of the teeth, the agglomerated lotus root powder is completely crushed. The crushed lotus root powder is collected by the inclined collection shell 56 and then falls into the conical shell 6 through the feeding pipe 58. The conical shell 6 plays a buffering and guiding role, so that the lotus root powder enters the lower conveying pipe 7 smoothly and finally falls accurately into the conveying mesh cylinder 81 inside the sterilization box 1. This process avoids the accumulation and blockage of lotus root powder during transportation through the structured conveying path, and at the same time ensures that the material enters the sterilization area evenly, laying the foundation for efficient sterilization.

[0019] In this embodiment, the sterilization mechanism 8 includes a conveying mesh cylinder 81 installed on the inner wall of the sterilization chamber 1. A conveying auger 82 is rotatably fitted to the inner wall of the conveying mesh cylinder 81. A conveying motor 83 is installed on one side of the sterilization chamber 1. A discharge pipe 84 is fixedly connected to the lower end of the conveying mesh cylinder 81. A spiral tube 85 is installed on the upper side of the inner wall of the sterilization chamber 1. An air inlet pipe 86 is fixedly connected to one end of the spiral tube 85, and an air outlet pipe 87 is fixedly connected to the other end of the spiral tube 85. A plurality of air outlet micro-holes 88 are evenly arranged on the side of the spiral tube 85 facing the conveying mesh cylinder 81. The upper ends of the air inlet pipe 86 and the air outlet pipe 87 both extend to the upper side of the sterilization chamber 1. The output end of the conveying motor 83 extends into the interior of the sterilization chamber 1 and is fixedly connected to one end of the conveying auger 82. The lower end of the discharge pipe 84 extends to the lower side of the sterilization chamber 1. The mating part between the conveying mesh cylinder 81 and the spiral tube 85 is a stainless steel powder sintered mesh. The lower end of the conveying pipe 7 extends into the interior of one end of the conveying mesh cylinder 81. After the sterilization mechanism 8 is started, the conveying motor 83 drives the conveying auger 82 inside the conveying mesh cylinder 81 to rotate, pushing the lotus root powder to move slowly along the conveying mesh cylinder 81. The external ozone generator introduces ozone into the spiral tube 85 through the air inlet pipe 86. The ozone is sprayed out through the spiral tube 85 toward multiple air outlet micro-holes 88 of the conveying mesh cylinder 81. It fully contacts the lotus root powder inside through the stainless steel powder sintered mesh (which has both air permeability and barrier properties) of the conveying mesh cylinder 81, achieving sterilization. The sterilized lotus root powder is discharged through the discharge pipe 84. The residual ozone that has not participated in the reaction is discharged and treated through the air outlet pipe 87. In this stage, the combination of dynamic conveying and ozone penetration ensures that the lotus root powder is in continuous contact with ozone during the movement, improving the sterilization efficiency and thoroughness, while preventing ozone leakage.

[0020] When using the device, fresh lotus root powder is first mechanically crushed by the crushing and cutting rollers 52 and 53 of the crushing mechanism 5, and then dispersed by the airflow from the jet head 12 driven by the air pump 9 to form loose particles. The loose lotus root powder enters the conveying mesh cylinder 81 of the sterilization box 1 through the conical shell 6 and the conveying pipe 7, and is pushed forward by the conveying auger 82. At the same time, ozone sprayed from the spiral tube 85 passes through the conveying mesh cylinder 81 and comes into contact with the lotus root powder to complete sterilization. Finally, the sterilized lotus root powder is discharged from the discharge pipe 84. The air pressure balance valve 13 and the air outlet pipe 87 respectively regulate the air pressure in the box and treat residual ozone. The entire process improves the problem of incomplete sterilization caused by lotus root powder clumping through the continuous design of pretreatment dispersion, dynamic conveying and ozone penetration sterilization, and achieves continuous and efficient sterilization.
