Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural product preservation, and in particular relates to a lotus root anti-brown spot preservation container. Background Art

[0002] Lotus root is a nutritious and widely consumed aquatic plant. Its storage and preservation have always been an important issue of concern to the agriculture and food industry. Lotus root is prone to brown spots and corruption during storage, resulting in a significant decrease in its commercial value and edible value. There are many existing preservation methods, but they still face some technical difficulties.

[0003] The main reason for the brown spots on lotus roots during storage is the activity of polyphenol oxidase (PPO). Phenol oxidase catalyzes the oxidation reaction of polyphenols to generate quinones, which further polymerize to form brown pigments, causing brown spots on the surface of lotus roots. In addition, the respiration of lotus roots during storage will produce moisture. If the humidity inside the container is too high, mold and bacteria are likely to grow, causing the lotus roots to rot and deteriorate. Traditional preservation methods, such as the use of chemical preservatives and low-temperature storage, can delay the occurrence of brown spots and corruption of lotus roots to a certain extent, but there are problems of chemical residues and high energy consumption, which cannot meet the requirements of modern people for health and environmental protection.

[0004] However, the prior art still has some shortcomings. The existing fresh-keeping containers may have problems such as complicated operation, difficulty in cleaning, and uneven release of antioxidants and microbial inhibitors during design and use. In addition, how to improve the preservation effect of lotus root without increasing the cost of the container is still a technical problem that needs to be solved urgently. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a lotus root anti-brown spot preservation container, which can realize an efficient, environmentally friendly and easy-to-operate lotus root anti-brown spot preservation container, thereby significantly improving the storage quality and preservation effect of lotus root.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A lotus root anti-brown spot preservation container comprises a base, a splicing bin is arranged on the top of the base, the number of the splicing bins is set to be multiple, and a bin cover is arranged above the top splicing bin;

[0008] Both ends of the splicing bin are symmetrically provided with quick-release lock buckles, which are used to connect the adjacent base, splicing bin and bin cover together;

[0009] The interior of the splicing bin is movably connected with a partition by plugging, and a filling bin is provided on the top of the partition, and the filling bin is filled with an antioxidant;

[0010] A receiving cavity is provided on the top of the base, and a sponge pad is laid on the bottom of the receiving cavity.

[0011] Furthermore, through grooves are evenly opened at the bottom of the splicing bin, limiting grooves are opened at the top of the bin cover, and second air holes are evenly opened at the bottom of the limiting grooves.

[0012] Furthermore, an inner support piece is engaged with the inner side of the limiting groove, a gripping rod is fixedly connected to the middle of the inner support piece, and a microporous membrane is laid between the inner support piece and the limiting groove.

[0013] Furthermore, a plug-in block adapted to the through slot is fixedly connected to the bottom of the separator;

[0014] First ventilation holes are evenly opened on both sides of the partition.

[0015] Furthermore, a first positioning member is fixedly connected to the bottom of the splicing bin, and a second positioning member is fixedly connected to the bottom of the bin cover, and both the first positioning member and the second positioning member are in contact with the inner side of the bin opening of the splicing bin;

[0016] Both ends of the splicing bin are provided with hand grip grooves.

[0017] Furthermore, a foot pad is symmetrically fixedly connected to the bottom of the base.

[0018] Furthermore, the quick-release lock includes a support plate and a positioning plate;

[0019] A pin-jointed plate is symmetrically and fixedly connected to the side surface of one end of the support plate, and an elbow is fixedly connected to one end of the positioning plate;

[0020] A driving arm is rotatably connected inside the pin-jointed plate, a pin-jointed hole is penetrated through the side surface of the driving arm, a pull rod is rotatably connected inside the driving arm, and a positioning ring is arranged at one end of the pull rod.

[0021] Furthermore, a pin connection seat is provided on the pull rod, and the pull rod is connected to the pin connection hole through a pin.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] First, the utility model sets a filling bin inside the splicing bin, and puts natural antioxidants, such as vitamin C or tea polyphenols, in the filling bin. Antioxidants can inhibit the activity of phenol oxidase (PPO), delay the oxidation of phenolic substances, and prevent brown spots from appearing on the surface of lotus roots. This design makes full use of the preservation effect of natural substances, avoids the use of chemical preservatives, and meets the needs of modern people for health and environmental protection.

[0024] Secondly, microbial inhibitors, such as lactic acid bacteria fermentation liquid or grapefruit seed extract, are placed in the container. These inhibitors can effectively inhibit the growth of mold and bacteria, preventing the lotus root from spoiling during storage. Combined with the use of sponge pads, it can absorb excess moisture generated during the breathing process of the lotus root, keep the inside of the container dry, and further prevent mold growth.

[0025] Furthermore, the microporous membrane inside the container allows gas exchange but prevents microorganisms from entering, thereby controlling the oxygen and carbon dioxide concentrations inside the container. This design helps inhibit the activity of phenol oxidase, prevents the formation of brown spots, and also inhibits the growth of mold. The application of microporous membrane improves the storage quality of lotus root and extends its shelf life.

[0026] In addition, the utility model designs a quick-release lock structure for the splicing bin and the bin cover, making the installation and removal of the container more convenient and quick. The quick-release lock realizes a stable connection between the splicing bins through the operation of the driving arm and the positioning ring, ensuring the stability and sealing of the container during use. The partitions arranged inside the splicing bin can not only isolate the lotus roots and prevent mechanical damage, but also ensure air circulation inside the container through the first air vent and the through groove design, providing a suitable storage environment.
