Abstract
Description
Technical Field
[0001] This utility model relates to the field of food storage technology, specifically a food moisture-proof storage device. Background Technology
[0002] Food has a shelf life after production, which is a standard used to measure the growth of microorganisms. When the microbial count exceeds the standard, consumption will lead to adverse reactions in the human body. High humidity during food storage will accelerate this process, causing the food to expire prematurely and resulting in food safety issues. Therefore, it is recommended that food manufacturers take appropriate moisture-proofing and dehumidification measures during food processing and storage.
[0003] Currently, most food moisture-proof storage devices on the market have a simple structure. They contain several desiccant packets that are replaced periodically for static solid adsorption and dehumidification. While they can achieve a certain dehumidification effect in a small space, the air inside the device is not flowing, and the desiccant packets are stacked on top of each other, resulting in a limited contact area between the desiccant and the air. This leads to low dehumidification efficiency and makes it difficult to determine whether the desiccant can still be used, which is not conducive to the replacement and management of the desiccant packets. In addition, the food industry has high requirements for air cleanliness. Bacteria in the air can accelerate the spoilage of food and shorten its storage period. Spoiled food can also produce odors and harmful gases in the air. Therefore, sterilizing the air and purifying it of odors and harmful gases is also an essential step. Utility Model Content
[0004] The purpose of this invention is to provide a food moisture-proof storage device that solves the problem in the prior art where desiccants are used for drying, but the gas inside the device does not flow and the desiccant packets are stacked on top of each other, resulting in a limited contact area between the desiccant and the air and low dehumidification efficiency.
[0005] To achieve the above objectives, a food moisture-proof storage device is provided, comprising a storage box, a door hinged to the outer end of the storage box, a second moisture-proof box penetrating through one outer end of the storage box, an air inlet pipe penetrating through the other end of the second moisture-proof box, an air inlet fan disposed in the middle of the air inlet pipe, a first moisture-proof box penetrating through the other outer end of the storage box, an exhaust pipe penetrating through the other end of the first moisture-proof box, and an exhaust fan disposed in the middle of the exhaust pipe;

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4 This utility model provides a technical solution: a food moisture-proof storage device, including a storage box 1, a door 10 hinged to the outer end of the storage box 1, a moisture-proof box 2 7 passing through one end of the outer side of the storage box 1, an air inlet pipe 8 passing through the other end of the moisture-proof box 2 7, an air inlet fan 9 in the middle of the air inlet pipe 8, a moisture-proof box 2 passing through the other end of the outer side of the storage box 1, an exhaust pipe 4 passing through the other end of the moisture-proof box 2, and an exhaust fan 3 in the middle of the exhaust pipe 4. By activating the air inlet fan 9 and the exhaust fan 4, air circulation inside the storage box 1 can be ensured, thereby improving the storage effect of food.
[0023] The storage box 1 is fixedly connected to a placement plate 5 inside. A humidity sensor 11 is fixedly connected to the upper inner side of the storage box 1. An ultraviolet germicidal lamp 12 is installed on one side of the humidity sensor 11. A bracket 6 is fixedly connected to the four ends of the bottom of the storage box 1. The humidity sensor 11 can monitor the humidity inside the box in real time. A controller is set on the door 10. When the humidity inside the box exceeds the preset value, the controller can control the air intake and exhaust components at both ends to work. The ultraviolet germicidal lamp 12 can sterilize and disinfect the air inside the box. The ultraviolet germicidal lamp 12 usually only needs to be turned on for half an hour. It does not need to be turned on for too long to avoid damaging the food.
[0024] A fixing plate 18 is fixedly connected inside both the first and second moisture-proof boxes 2 and 7. A mounting bracket 14 is installed at the inner end of the fixing plate 18. A drying box 15 is installed at the bottom inner side of the mounting bracket 14. An activated carbon adsorption mesh plate 16 is installed at the other end of the drying box 15. A filter plate 17 is installed at the other end of the activated carbon adsorption mesh plate 16. After the air enters the moisture-proof box, it can filter and adsorb dust and impurities in the air through the internal filter plate 17 and activated carbon adsorption mesh plate 16, thereby improving the protection of food. The desiccant inside the drying box 15 can dry the air, thereby achieving the ventilation and moisture-proof storage effect of the entire storage device. The drying shell 15 has a through-hole design at both ends and is filled with desiccant. The air can be dried after passing through the desiccant, achieving a rapid drying effect.
[0025] Both the inner ends of the first and second moisture-proof boxes 2 and 7 are provided with sliding grooves 19. A sliding rod 22 is fixedly connected to the inner end of the sliding groove 19. A slider 21 is slidably connected to the sliding rod 22. A movable plate 20 is fixedly connected to the slider 21 outwards. A spring 23 is sleeved on the sliding rod 22. One end of the spring 23 is fixedly connected to the slider 21, and the other end is fixedly connected to the inner end of the sliding groove 19. Two pairs of positioning posts 13 are fixedly connected to one end of the movable plate 20. Positioning holes 24 are provided through the fixed plate 18 and the mounting bracket 14. The positioning posts 13 correspond to the positioning holes 24. When the operator needs to disassemble the moisture-proof filter assembly, they first pull the movable plate 20 outwards. Under the action of the slider 21 and the spring 23, the movable plate 20 moves outwards. At this time, the movable plate 20 drives the positioning posts 13 away from the inside of the positioning holes 24. The operator can then directly pull out the mounting bracket 14 to disassemble and replace the moisture-proof filter assembly, improving the filtration and moisture-proof effect of the device.
[0026] Working principle: During use, the staff places the food on the placement plate 5 and closes the cabinet door 10 to store the food. The cabinet door 10 is equipped with a controller that is electrically connected to the internal humidity sensor 11 and ultraviolet germicidal lamp 12. The controller controls the coordinated operation of the two electronic components. The humidity sensor 11 and ultraviolet germicidal lamp 12 work to sterilize and disinfect the air inside the cabinet. At the same time, the humidity sensor 11 can detect the humidity. When the humidity inside the cabinet exceeds the preset value, the intake fan 9 and exhaust fan 3 are activated, thereby allowing the air inside the cabinet to circulate and achieve the effect of ventilation storage. After the air enters the moisture-proof cabinet, it passes through the internal filter plate 17 and activated carbon adsorption mesh plate 16 to filter and adsorb dust and impurities in the air, improving the protection of food. The desiccant inside the drying box 15 can dry the air, thereby achieving the ventilation and moisture-proof storage effect of the entire storage device.
[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
