Storage and preservation device for panax japonicus

Abstract

This utility model discloses a storage and preservation device for bamboo-joint ginseng, including a sealed box. A light-shielding layer is fixedly installed on the inner wall of the sealed box, and the box is divided into multiple inner cavities by at least one dividing layer. A drawer unit is slidably installed in each inner cavity, and the bottom of the drawer unit is provided with a wavy, hollowed-out elastic silicone mesh tray. The light-shielding layer is connected to the lower part of the dividing layer via a disassembly and assembly mechanism. This utility model offers upgraded physical protection: the hollowed-out structure of the wavy, elastic silicone mesh tray disperses the stress on the bamboo-joint ginseng nodes, resulting in a reduced fracture rate when the ginseng is subjected to a 500g load. The light-shielding layer is efficiently disassembled and assembled: the Y-shaped insertion groove and the inclined guide design of the limiting block shorten the replacement time of the light-shielding layer, and the elastic component automatically locks to prevent loosening.

Description

Technical Field

[0001] This utility model belongs to the technical field of storage and preservation devices, and particularly relates to a storage and preservation device for bamboo joint ginseng. Background Technology

[0002] As a high-value traditional Chinese medicine, the bamboo joint ginseng is difficult to store due to its multi-segmented and brittle morphology and the photothermal sensitivity of its saponin active ingredients. Currently, the industry generally uses traditional drying boxes or cold storage for preservation.

[0003] In the field of ginseng storage, light-induced degradation of active ingredients is a core problem that has long remained unresolved. Existing technologies generally rely on low temperature and low humidity control, but seriously underestimate the destructive effects of visible light and ultraviolet light on saponins. Utility Model Content

[0004] This utility model addresses the problems existing in the prior art by proposing the following technical solution:

[0005] A storage and preservation device for ginseng includes a sealed box, the inner wall of which is fixedly fitted with a light-shielding layer, and the box is divided into multiple inner cavities by at least one dividing layer; each inner cavity has a drawer unit that is slidably installed, and the bottom of the drawer unit is provided with a wavy hollow structure elastic silicone mesh tray; the light-shielding layer is connected to the bottom of the dividing layer by a disassembly and assembly mechanism.

[0006] As a preferred embodiment of the above technical solution, the disassembly and assembly mechanism includes: a connecting block fixed to the bottom of the light-shielding layer, a mounting plate fixedly connected to the connecting block, a limiting block vertically set at the bottom of the mounting plate, a Y-shaped insertion groove that is inserted into the limiting block, a fixed seat that supports the insertion groove, insertion rods symmetrically inserted into the side wall of the fixed seat, a side pull plate fixedly connected to the outer end of the insertion rod, and an elastic element connecting the side pull plate and the side plate of the sealing box; a gas replacement mixing valve is installed on the top of the sealing box, and a humidity regulating box is embedded in the side wall.

[0007] As a preferred embodiment of the above technical solution, the wavy perforated mesh of the elastic silicone mesh support plate has a hole diameter of 5-15mm and a height difference between the crest and trough of the wave of 10±2mm.

[0008] As a preferred embodiment of the above technical solution, the light-shielding layer is a composite layered structure, comprising a 0.05-0.1 μm thick nano-silver coating and a 0.8-1.2 mm thick polyester substrate.

[0009] The beneficial effects of this utility model are as follows:

[0010] In this application, physical protection is upgraded: the hollow structure of the wavy elastic silicone mesh support plate disperses the stress of the bamboo joint joints of the ginseng, and the fracture rate of the ginseng body decreases when the actual load is 500g.

[0011] Efficient installation and removal of the light-shielding layer: The Y-shaped insertion groove and the inclined guide design of the limiting block shorten the replacement time of the light-shielding layer, and the elastic element automatically locks to prevent loosening;

[0012] Environmental control optimization: The nano-silver coating of the light-shielding layer increases the UV reflectivity, and works in conjunction with the gas replacement mixing valve to maintain the O2 concentration ≤3%, enabling the saponin retention rate to reach 91.5% after 180 days;

[0013] Enhanced structural reliability: The interference fit between the plug rod and the fixed seat can withstand thermal expansion and contraction from -20℃ to 60℃, ensuring no displacement under high and low temperature environments. Attached Figure Description

Elastic silicone mesh support plate. Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0019] like Figure 1 and Figure 2 As shown in the embodiment of this utility model, the bamboo joint ginseng storage and preservation device includes a sealed box 1, which is welded from 304 stainless steel. Its inner wall is seamlessly bonded with a light-shielding layer 7 through food-grade polyurethane adhesive, wherein the nano silver coating is 0.08μm thick and the polyester base fabric is 1.0m thick.

[0020] The interior of the box is divided into three inner cavities 6 by a horizontal dividing layer 2. Each inner cavity 6 has a drawer unit 5 that is slidably installed. A wavy elastic silicone mesh support plate 18 is fixed on the bottom plate 17 of the drawer unit 5. The mesh has a hole diameter of 8mm and a wave peak spacing of 12mm, which is used to support the nodule part of the bamboo joint.

[0021] The light-shielding layer 7 is connected via a disassembly and assembly mechanism: First, fix the fixing base 16 to the bottom surface of the dividing layer 2 with bolts. Pull the side pull plate 12 outward to retract the plug rod 13. Align the limiting block 14 with the Y-shaped plug groove 15 and insert it. Then, release the side pull plate 12. The elastic element 11 pushes the plug rod 13 into the side hole of the fixing base 16 to complete the locking. For disassembly, the light-shielding layer 7 can be pulled out for maintenance by reversing the operation.

[0022] Gas replacement mixing valve 3 is installed on the top of the chamber and is connected to nitrogen cylinder and carbon dioxide cylinder through a three-way pipe; humidity control box 4 is embedded in the side wall of the chamber and contains bamboo charcoal-silicone composite particles.

[0023] Working principle

[0024] Light-shielding and antibacterial: When the light source penetrates the sealed box 1, the nano-silver coating of the light-shielding layer 7 converts the light energy in the 280-780nm wavelength band into heat energy, which is diffused into the air in the inner cavity 6 through the polyester base fabric, blocking the photolysis reaction of saponins; at the same time, the nano-silver ions are released to inhibit the adhesion of mold.

[0025] Dynamic humidity control: When the humidity in the inner cavity 6 is greater than 65% RH, the bamboo charcoal in the humidity control box 4 preferentially adsorbs water molecules; when the humidity is less than 50% RH, the silica gel releases moisture to maintain a balance range of 55±5% RH.

[0026] Damage-proof loading and unloading: When the drawer unit 5 is pulled out, the wave structure of the elastic silicone mesh tray 18 absorbs vibration energy through deformation with a damping coefficient of 0.35, preventing the body from colliding with the hard base plate 17.

[0027] Quick maintenance: When removing the light-shielding layer 7, the side pull plate 12 is driven by external force to disengage the plug rod 13 from the fixed base 16, and the limit block 14 slides out along the inclined surface of the Y-shaped plug groove 15. The whole process requires no tools.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
