Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine preservation, and more specifically, to a nitrogen-locking device for wild Cordyceps sinensis. Background Technology

[0002] Wild Cordyceps sinensis, as an extremely precious traditional Chinese medicine, is rich in various nutrients such as cordyceps polysaccharides, adenosine, cordycepic acid, and cordyceps polypeptides, and has extremely high medicinal and economic value.

[0003] A search revealed an existing patent (publication number: CN222094172U) that discloses a Cordyceps sinensis cleaning device, including a cleaning tank, a filter circulation assembly, and a water outlet pipe. The other end of the water outlet pipe is detachably inserted through one side wall of the cleaning tank. A rotating drum is rotatably mounted inside the cleaning tank. Multiple placement cylinders are detachably threaded onto the side wall of the rotating drum, and multiple through holes are opened on the side wall of each placement cylinder. A circular tube is installed inside the rotating drum, and a water supply pipe is provided at the position of each placement cylinder on the side wall of the circular tube. One end of the circular tube is connected to a rotating pipe that rotatably penetrates one side wall of the cleaning tank, and the other end of the rotating pipe is rotatably connected to the water outlet pipe. The cleaning tank contains cleaning water sufficient to soak the rotating drum and multiple placement cylinders. This invention combines two methods—cleaning by impact and soaking—to improve the overall cleaning efficiency while enhancing the cleaning and protection of Cordyceps sinensis.

[0004] The existing method of using open containers to temporarily hold liquid nitrogen for wild Cordyceps sinensis involves manually splashing it onto the surface of the container. The liquid nitrogen evaporates very quickly, and the large droplets can only cool the bottom of the container. The Cordyceps sinensis on the top oxidizes and turns yellow due to insufficient cooling, which limits its use. In addition, the patent documents cited above do not propose any solutions to solve the above problems.

[0005] Therefore, a nitrogen-based freshness-locking device for wild Cordyceps sinensis is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a nitrogen-locking equipment for wild Cordyceps sinensis to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a nitrogen-based fresh-locking device for wild Cordyceps sinensis, comprising a sealed container, a connecting cap that is snapped onto the upper end of the sealed container, a fresh-keeping component being provided on the upper end of the connecting cap, the fresh-keeping component comprising a liquid nitrogen storage tank, a spray pipe being fixedly provided on one side of the liquid nitrogen storage tank, atomizing nozzles being fixedly provided at equal intervals at the bottom of the spray pipe, connecting rods being fixedly provided at all four ends of the bottom of the spray pipe, and a temperature sensor being fixedly provided on one side of the spray pipe.

[0008] Preferably, the sealed container is provided with a connecting assembly, which includes a fixing plate. The fixing plate is symmetrically and fixedly disposed on the inner wall of the sealed container, and a mesh plate is slidably connected to the outside of the fixing plate.

[0009] Preferably, each of the mesh plates has a connecting block fixedly connected to its upper end. A limiting rod is connected through the inside of the connecting block, and the limiting rod passes through a limiting hole inside the fixed plate. A limiting sleeve is sleeved on one side of the limiting rod.

[0010] Preferably, a sealing strip is fixedly provided at the bottom of the connecting cover, and the sealing strip is in close contact with the surface of the sealing container.

[0011] Preferably, an air exhaust pipe is fixedly installed on one side of the upper end of the connecting cover, and a one-way valve is fixedly installed on one side of the air exhaust pipe.

[0012] Preferably, an injection pipe is provided on one side of the upper end of the connecting cover, a pressure sensor is provided on one side of the injection pipe, and a flow control valve is provided on one side of the pressure sensor.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] Compared with existing technologies, this nitrogen-locking equipment for wild Cordyceps sinensis features a preservation component. The storage tank provides a continuous supply of liquid nitrogen, which is then delivered to the atomizing nozzle through a spray pipe. The nozzle atomizes the liquid nitrogen into micron-sized droplets that evenly cover the container surface. The resulting ice crystals are small, reducing damage to the cell structure and better preserving the original quality and nutritional components of the Cordyceps sinensis. Furthermore, the spraying time and flow rate can be automatically adjusted to ensure that each batch of Cordyceps sinensis is frozen within the optimal time, avoiding over-freezing or under-freezing, thus enhancing the practicality of the device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] As attached Figures 1 to 4 The device shown is a nitrogen-based fresh-locking device for wild Cordyceps sinensis, including a sealed container 1. A connecting cover 2 is snapped onto the upper end of the sealed container 1. A fresh-keeping component 3 is provided on the upper end of the connecting cover 2. The fresh-keeping component 3 includes a liquid nitrogen storage tank 31. A spray pipe 32 is fixedly provided on one side of the liquid nitrogen storage tank 31. Atomizing nozzles 33 are fixedly provided at equal intervals at the bottom of the spray pipe 32. Connecting rods 34 are fixedly provided at all four ends of the bottom of the spray pipe 32. A temperature sensor 35 is fixedly provided on one side of the spray pipe 32.

[0023] Specifically, the device is equipped with an atomizing nozzle 33, which provides a continuous supply of liquid nitrogen through a liquid nitrogen storage tank 31. The liquid nitrogen is then transported to the atomizing nozzle 33 through a spray pipe 32. The atomizing nozzle 33 atomizes the liquid nitrogen into micron-sized droplets and evenly covers the surface of the container. The resulting ice crystals are small, which reduces damage to the cell structure and better preserves the original quality and nutritional components of Cordyceps sinensis, thereby enhancing the practicality of the device.

[0024] Example 2

[0025] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0026] In a preferred embodiment, a connecting component 4 is provided inside the sealed container 1. The connecting component 4 includes a fixing plate 41, which is symmetrically and fixedly disposed on the inner wall of the sealed container 1. A mesh plate 42 is slidably connected to the outside of the fixing plate 41. Furthermore, by providing the mesh plate 42, the cordyceps is stored, making it more convenient to use.

[0027] In a preferred embodiment, a connecting block 44 is fixedly connected to the upper end of the mesh plate 42. A limiting rod 45 is connected through the inside of the connecting block 44, and the limiting rod 45 passes through the limiting hole 43 inside the fixing plate 41. A limiting sleeve 46 is sleeved on one side of the limiting rod 45. Furthermore, by setting the limiting sleeve 46, the limiting rod 45 is effectively limited, avoiding the phenomenon that the limiting rod 45 will fall off and cause the mesh plate 42 to fall off, thereby improving the stability of the mesh plate 42.

[0028] In a preferred embodiment, a sealing strip 5 is fixedly provided at the bottom of the connecting cover 2, and the sealing strip 5 is in close contact with the surface of the sealing container 1; furthermore, by providing the sealing strip 5, its sealing effect is further improved.

[0029] In a preferred embodiment, an air exhaust pipe 6 is fixedly provided on one side of the upper end of the connecting cover 2, and a one-way valve 7 is fixedly provided on one side of the air exhaust pipe 6; furthermore, by providing an air exhaust pipe 6, it is convenient to effectively exhaust air, which can effectively prevent the Cordyceps sinensis from being oxidized by oxygen in the air, thus enhancing the practicality of the device.

[0030] In a preferred embodiment, an injection pipe 8 is provided on one side of the upper end of the connecting cover 2, a pressure sensor 9 is provided on one side of the injection pipe 8, and a flow control valve 10 is provided on one side of the pressure sensor 9; furthermore, by providing the flow control valve 10, nitrogen is injected into the sealed container 1 at a suitable flow rate, thereby facilitating effective regulation and making its use more convenient.

[0031] The working process of this utility model is as follows:

[0032] In use, firstly, the Cordyceps sinensis is placed on the upper end of the mesh plate 42 inside the sealed container 1. Connecting blocks 44 are provided at both ends of the mesh plate 42, and a limiting rod 45 passes through the connecting blocks 44 and extends into the limiting hole 43 inside the fixed plate 41, thus limiting the mesh plate 42. This allows for height adjustment between the mesh plates 42 according to actual needs, making it more convenient to use. Furthermore, a limiting sleeve 46 is fitted onto one side of the limiting rod 45, further improving the stability of the connection between the mesh plate 42 and the fixed plate 41. Secondly, an injection pipe 8 is provided at the upper end of the connecting cover 2, and it works in conjunction with the flow control valve 10 on the injection pipe 8 to inject nitrogen into the sealed container 1 at a suitable flow rate. By observing the changes in the pressure sensor 9 and simultaneously monitoring the air discharge at the air exhaust pipe 6, when the pressure sensor 9 indicates that the pressure inside the sealed container 1 has reached normal atmospheric pressure and there is no longer significant gas discharge from the air exhaust pipe 6, it indicates that the air inside the sealed container 1 has been basically replaced. The flow control valve 10 is then closed. This system effectively prevents Cordyceps sinensis from being oxidized by oxygen in the air, while inhibiting its aerobic respiration and reducing the accumulation of metabolites, thus maintaining the freshness of Cordyceps sinensis. In addition, the sealing effect is further improved by connecting the cap 2 at the top of the sealed container 1 through the sealing strip 5, and it is also convenient to take out the Cordyceps sinensis inside, making it more convenient to use. Furthermore, a liquid nitrogen storage tank 31 is set on one side of the upper end of the connecting cap 2, and a spray pipe 32 is connected to the outside of the liquid nitrogen storage tank 31. Liquid nitrogen is then sprayed out through the atomizing nozzle 33 at the bottom of the spray pipe 32, and is evenly sprayed on the surface of the sealed container 1. The injection of nitrogen has a certain pre-cooling effect on the Cordyceps sinensis inside the sealed container 1. Then, the liquid nitrogen spraying is conducive to the rapid freezing of the Cordyceps sinensis in the container, reducing the amount of liquid nitrogen used and reducing costs. At the same time, the pre-cooling before liquid nitrogen spraying and freezing can effectively reduce the formation of large ice crystals, maximize the preservation of the cell structure of Cordyceps sinensis, improve its quality and nutritional components, and thus improve its practicality to a certain extent, making it more widely used.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
