Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vegetable processing, in particular to a steam return water sterilization device for drying dehydrated vegetables. Background Art
[0002] As people's focus on healthy eating continues to grow, dehydrated vegetables, as a convenient food format that preserves nutrients, are increasingly in demand in the food market. Consumers are also increasingly demanding the quality and safety of dehydrated vegetables, prohibiting the presence of harmful microorganisms and pathogens. Traditional drying processes may not completely eliminate microbial contamination, necessitating the introduction of effective sterilization devices in the drying process.
[0003] In traditional dehydrated vegetable drying and sterilization equipment, vegetables are often kept stationary, making it impossible to turn them over during the drying and sterilization process. This leads to uneven heating and sterilization treatment of different parts of the dehydrated vegetables. For example, during drying, the top of the vegetable may become over-dried or even burnt due to prolonged contact with the bottom of the drying equipment, while the bottom may still not reach the ideal dryness, with a high amount of residual moisture, affecting the overall drying effect and product quality consistency. Furthermore, due to the inability to turn the vegetables over, one side of the vegetable may be fully sterilized, while the other side may be incompletely sterilized, leaving harmful microorganisms. This greatly increases the risk of product deterioration during subsequent storage and transportation, posing a potential threat to consumer health. Furthermore, when drying and sterilization are suspended, the drying fan and UV sterilizer are idle. Due to their poorly designed location, they can easily be located below the steam pipe, causing moisture to enter key components such as the driver board. Once the driver board gets damp, it may cause problems such as circuit short circuit and corrosion, which not only affects the normal service life of the equipment, but also increases equipment maintenance costs and downtime, reduces production efficiency, and has an adverse impact on the company's economic benefits.

Detailed implementation mode
[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0024] As Figures 1-5 shown, the present invention provides a technical solution: a steam return water sterilization device for dehydrated vegetable drying, including a drying and sterilizing bin 1, a material rack 2 fixedly connected inside the drying and sterilizing bin 1, a position adjustment bin 3 fixedly connected to the top of the drying and sterilizing bin 1, a position adjustment motor 4 fixedly connected to the left part of the top of the position adjustment bin 3, a position adjustment lead screw 5 fixedly connected to the driving end of the position adjustment motor 4, the position adjustment lead screw 5 passing through the top of the position adjustment bin 3 and rotatably connected to the inner wall of the bottom of the position adjustment bin 3, a position adjustment plate 6 threadedly connected to the position adjustment lead screw 5, an ultraviolet lamp 7 fixedly connected to the bottom of the position adjustment plate 6, a drying fan 8 fixedly connected to the bottom of the position adjustment plate 6, a mounting frame 9 fixedly connected to the middle of the right side of the drying and sterilizing bin 1, a steam generator 10 fixedly connected to the top of the mounting frame 9, the material rack 2 including a fixed bin 11 and a turning motor 12, a through slot 13 opened at the bottom of the fixed bin 11, two turning guide bars 14 fixedly connected to the inner wall of the bottom of the fixed bin 11, a turning material bin 15 slidably connected inside the fixed bin 11, two return springs 16 fixedly connected to the left side of the turning material bin 15, the turning motor 12 fixedly connected to the inner wall of the right side of the drying and sterilizing bin 1, a turning cam 17 fixedly connected to the driving end of the turning motor 12, a threaded hole 18 for threaded connection with the position adjustment lead screw 5 opened on the position adjustment plate 6, an avoidance groove 19 opened on the position adjustment plate 6, two guide holes 20 opened on the position adjustment plate 6 on both sides before and after the threaded hole 18, and two guide rods 21 fixedly connected to the left side inside the position adjustment bin 3 and adapted to the guide holes 20;
[0025] In this embodiment, by providing a material rack 2 that can turn over dehydrated vegetables, it is ensured that the materials are turned over during drying and sterilization, and the materials are no longer in a static state. After placing the materials in the turnover bin 15, start the steam generator 10 to generate high-temperature steam, and transport the steam to the drying and sterilization bin 1 through the steam pipe 22 for energy-saving sterilization. Then start the turnover motor 12, and the turnover motor 12 drives the turnover cam 17 to rotate, so that the turnover bin 15 slides inside the fixed bin 11 through the turnover guide bar 14. When the convex end of the cam reaches the other side, the turnover bin 15 is reset due to the power provided by the return spring 16. Repeating this way, the dehydrated vegetables inside the turnover bin 15 can be turned over by moving left and right. Also provided is an adjustment plate 6 that can drive the ultraviolet lamp 7 and the drying fan 8 to adjust their positions. When the steam head 23 transports steam, the adjustment motor 4 can be started to drive the adjustment screw rod 5 to rotate. Through the thread connection and the guidance of the guide rod 21, the adjustment plate 6 moves upward. At this time, the adjustment plate 6 is located above the steam outlet. After the steam transportation process ends, start the adjustment motor 4 to rotate in the opposite direction, so that the adjustment plate 6 moves downward, making the ultraviolet lamp 7 and the drying fan 8 closer to the materials, facilitating secondary sterilization and drying. The steam generator 10 heats water to the boiling point, converting it from a liquid state to a gaseous state, thereby generating steam. When the steam reaches a certain pressure, it is output to the drying and sterilization bin 1 through the steam pipe 22. The drying fan 8 is equipped with an impeller to suck in air, and there is an electric heating wire at the air outlet to heat the air. The heated air dries the materials.
[0026] As Figures 1-3 shown, the top of the steam generator 10 is fixedly connected to a steam pipe 22, and the other end of the steam pipe 22 is fixedly connected to a steam head 23. The steam head 23 is located in the middle of the adjustment bin 3. The bottom of the drying and sterilization bin 1 is fixedly connected to a return water bin 24. A return water pipe 25 is fixedly connected between the return water bin 24 and the steam generator 10. An inlet water pipe 26 is fixedly connected to the steam generator 10. A filter plate 27 is provided between the drying and sterilization bin 1 and the return water bin 24. The front of the filter plate 27 is fixedly connected to a filter plate handle 28. The front of the drying and sterilization bin 1 is hinged with a sealing door 29. An observation window 30 is fixedly connected to the sealing door 29. A door handle 31 is fixedly connected to the front of the sealing door 29;
[0027] In this embodiment, after the steam releases heat in the drying and sterilization bin 1, it will turn into return water. This return water is recovered through the return water pipe 25. After removing impurities through the filter plate 27, it can be re-circulated back to the steam generator 10 for re-heating. After putting in the materials, the sealing door 29 can be closed to ensure the tightness of the device during drying and steam disinfection.
[0028] Working principle: By setting up a material rack 2 that can turn over dehydrated vegetables, it can ensure that the materials are turned over during drying and sterilization, and the materials are no longer in a static state. After placing the materials in the turnover bin 15, start the steam generator 10 to generate high-temperature steam, and transport the steam to the drying and sterilization bin 1 through the steam pipe 22 for energy-saving sterilization. Then start the turnover motor 12, and the turnover motor 12 drives the turnover cam 17 to rotate, so that the turnover bin 15 slides inside the fixed bin 11 through the turnover guide bar 14. When the convex end of the cam reaches the other side, the turnover bin 15 is reset due to the power provided by the return spring 16. Repeating this way, the dehydrated vegetables inside the turnover bin 15 can be turned over by moving left and right. Also, a position adjustment plate 6 is provided that can drive the ultraviolet lamp 7 and the drying fan 8 to adjust their positions. When the steam head 23 transports steam, the position adjustment motor 4 can be started to drive the position adjustment screw rod 5 to rotate. Through the thread connection and the guidance of the guide rod 21, the position adjustment plate 6 moves upward. At this time, the position adjustment plate 6 is above the steam outlet. After the steam transportation process ends, start the position adjustment motor 4 to rotate in the opposite direction, so that the position adjustment plate 6 moves downward, making the ultraviolet lamp 7 and the drying fan 8 closer to the materials, facilitating secondary sterilization and drying.
