Description

Technical Field

[0001] This utility model relates to the field of medicinal material freezing and insecticidal technology, specifically a medicinal material rapid freezing rack. Background Technology

[0002] Traditional Chinese medicinal herbs are an important industry in many parts of my country. In recent years, the country has strongly supported the development of the traditional Chinese medicine industry, and the planting area of ​​medicinal herbs has continued to expand. Storage is a crucial link in preserving and increasing the value of medicinal herbs. However, because medicinal herbs are rich in nutrients such as sugars and proteins needed by pests, they provide a suitable living environment for pests to grow and develop, leading to pests consuming the herbs. Generally, sealed plastic film tents or cold storage are used for storage. Nitrogen gas is filled into the plastic tents or cold storage to replace the air inside the tents or cold storage, killing microorganisms and pests, reducing oxidation and deterioration of the herbs, and achieving green, safe, and long-term storage of medicinal herbs.

[0003] For cold storage, the common practice is to push carts containing Chinese medicinal herbs into the cold storage, freeze them at around -10 to -20 degrees Celsius for a period of time, then activate a vacuum system to remove air, and finally introduce nitrogen or carbon dioxide (such as liquid nitrogen or solid carbon dioxide / dry ice) to kill pests and their eggs. This method offers the advantages of low-temperature and modified atmosphere storage for pest control. However, existing carts for storing Chinese medicinal herbs typically use shelves or mesh panels. Shelves have poor air permeability, hindering heat and gas exchange and resulting in low efficiency and uneven pest control during freezing. While mesh panels offer better air permeability, they can easily damage the herbs, leading to a decline in quality. Utility Model Content

[0004] The purpose of this invention is to provide a fast-freezing rack for medicinal materials with good air permeability. This fast-freezing rack can accelerate the freezing and insecticidal efficiency and kill insects more evenly, so as to solve the problem of poor air permeability of the medicinal material rack mentioned in the background art, which leads to inconvenience in air permeability of the medicinal materials.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rapid freezing rack for medicinal materials includes a frame body and several storage structures arranged vertically at intervals within the frame body. Each storage structure includes a tray, a partition, and an air pipe. There are two trays, which are fixedly arranged at both ends of the frame body. The two ends of the partition are movably arranged on the corresponding trays. The top surface of the partition has several evenly distributed clearance grooves. The bottom of each clearance groove has a vent hole penetrating the partition. Multiple air pipes are arranged at intervals on the top surface of the partition. The wall of each air pipe has several evenly distributed air outlets.

[0007] Preferably, the top surface of the tray is provided with a guide rail protruding along its length, and the partition has guide grooves on both edges of its bottom surface that fit on the guide rail.

[0008] Preferably, the two edges of the top surface of the partition protrude from the middle of the partition to form a retaining portion.

[0009] Preferably, the top surface of the retaining part is provided with a limiting groove that extends through to the guide groove along its length direction.

[0010] Preferably, the storage structure includes a limiting stop near one end of the guide rail. The limiting stop is T-shaped and includes a screw part and a pressure rod part that is perpendicularly connected to the screw part. The screw part passes downward through the limiting groove and the guide groove and is screwed onto the guide rail. The pressure rod part presses against the top surface of the holding part.

[0011] Preferably, the width of the pressure rod portion is smaller than the width of the limiting groove.

[0012] Preferably, the frame is an open square frame structure.

[0013] Preferably, the bottom surface of the frame is equipped with symmetrically arranged casters.

[0014] Preferably, the clearance groove is semi-circular.

[0015] Preferably, one end of the trachea is connected to an interface.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The evenly distributed ventilation holes on the partition accelerate the heat exchange of the medicinal materials on the partition, and the good air permeability can accelerate the freezing and insecticidal efficiency; at the same time, cold air or nitrogen is sprayed onto the medicinal materials through the evenly distributed air outlets on the air pipe, making the insecticidal effect more uniform; the avoidance groove is semi-circular, which can reduce the contact between the medicinal materials and the ventilation holes, prevent the ventilation holes from being blocked, facilitate the ventilation of the medicinal materials, and also avoid uneven insecticidal effect.

[0018] 2. The pressure bar presses against the top surface of the holding part. When the partition slides along the guide rail of the support plate and is pulled out, the screw part of the limit stop can restrict the partition from being pulled out of the frame. At the same time, the pressure bar can prevent the partition from tilting upward and avoid the partition from falling off the frame.

[0019] 3. The width of the pressure rod is smaller than the width of the limiting groove so that the pressure rod can pass through the limiting groove. When the partition needs to be removed for cleaning, simply rotate the limiting stop 90° so that the pressure rod is parallel to the length of the limiting groove. At this time, the pressure rod no longer restricts the partition from moving upward, and the partition can be lifted upward relative to the support plate to remove the partition. The structure is simple and easy to disassemble and assemble. Attached Figure Description

[0026] 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.

[0027] Please see Figure 1-3 A rapid freezing rack for medicinal materials includes a frame body 1 and several storage structures 2 arranged vertically at intervals within the frame body 1. The frame body 1 is an open square frame structure. Each storage structure 2 includes a tray 21, a partition 22, and an air pipe 23. There are two trays 21, which are fixedly installed at both ends of the frame body 1. The two ends of the partition 22 are movably mounted on the corresponding trays 21, and the partitions 22 can be partially pulled out relative to the trays 21. The top surface of the partition 22 has several evenly distributed clearance grooves 221, and the bottom of each clearance groove 221 has a vent hole 222 penetrating the partition 22. In this embodiment, multiple air pipes 23 are provided, laid at intervals on the top surface of the partitions 22, and the wall of each air pipe 23 has several evenly distributed air outlet holes 231.

[0028] One end of the air pipe 23 is connected to an interface 232, which is used to connect to an external air supply device. The external air supply device supplies cold air or nitrogen to the air pipe 23 through the interface 232.

[0029] In this embodiment, the heat exchange of the medicinal materials on the partition 22 is accelerated by the evenly distributed ventilation holes 222 on the partition 22, which has good air permeability and can accelerate the freezing and insecticidal efficiency. At the same time, cold air or nitrogen is sprayed onto the medicinal materials through the evenly distributed air outlet holes 231 on the air pipe 23, making the insecticidal effect more uniform. The avoidance groove 221 is semi-circular, which can reduce the contact between the medicinal materials and the ventilation holes 222, prevent the ventilation holes 222 from being blocked, facilitate the ventilation of the medicinal materials, and also avoid uneven insecticidal effect.

[0030] Please see Figure 1-2 as well as Figure 4 The top surface of the pallet 21 has a guide rail 211 protruding along its length. The partition 22 has guide grooves 223 on its bottom surface at both edges that fit onto the guide rails 211. The partition 22 slides out of the frame 1 through the guide grooves 223. Please refer to Figure 2-3 The two edges of the top surface of the partition 22 protrude from the middle of the partition 22 to form a retaining part 224, which can be used to prevent the medicinal materials from falling off the partition 22.

[0031] Please see Figure 2-4 The top surface of the holding part 224 is provided with a limiting groove 225 that extends through the guide groove 223 along its length. The storage structure 2 includes a limiting stop 24 disposed near one end of the guide rail 211. In this embodiment, the limiting stop 24 is T-shaped and includes a screw part 241 and a pressure rod part 242 that is perpendicularly connected to the screw part 241. The screw part 241 passes downward through the limiting groove 225 and the guide groove 223 in sequence and is screwed onto the guide rail 211. The pressure rod part 242 presses against the top surface of the holding part 224. When the partition 22 slides along the guide rail 211 of the support plate 21 and is pulled out, the screw part 241 of the limiting stop 24 can restrict the partition 22 from being pulled out of the frame 1. At the same time, the pressure rod part 242 can prevent the partition 22 from tilting upward and avoid the partition 22 from falling off the frame 1. At this time, the pressure rod part 242 is perpendicular to the groove length direction of the limiting groove 225.

[0032] Please see Figure 5 In this embodiment, the width of the pressure rod 242 is smaller than the width of the limiting groove 225, so that the pressure rod 242 can pass through the limiting groove 225. When the partition 22 needs to be removed for cleaning, it is only necessary to rotate the limiting stop 24 by 90° so that the pressure rod 242 is parallel to the groove length direction of the limiting groove 225. At this time, the pressure rod 242 no longer restricts the upward movement of the partition 22, and the partition 22 can be lifted upward relative to the support plate 21 to complete the removal of the partition 22. The structure is simple and the disassembly and assembly are convenient.

[0033] In this embodiment, a handle (not shown) is provided on the partition 22 to facilitate the removal of the partition 22 from the frame.

[0034] Please see Figure 1 The frame 1 is equipped with symmetrically arranged casters 3 on its bottom surface to facilitate pushing or pushing the frame 1 into or out of the cold storage.

[0035] The working principle of this novel rapid freezing shelf for medicinal materials is as follows: When performing insecticidal operations, the shelf 1 is first pushed into the cold storage and the cold storage is sealed using the casters 3. The shelf is then frozen at approximately -10 to -20 degrees Celsius for a period of time, followed by vacuuming to remove air. Then, cold air or nitrogen is supplied to the air pipe 23 via an external air supply device. The cold air or nitrogen is sprayed onto the medicinal materials through the air outlet 231 on the air pipe 23. The cold air or nitrogen can also come into contact with the medicinal materials through the vent 222, improving heat exchange between the medicinal materials and the gas, thereby accelerating the freezing and insecticidal efficiency. When it is necessary to collect the medicinal materials, the partition 22 can be slid along the guide rail 211 of the tray 21 and pulled out until the partition 22 is stopped by the screw part 241 of the limiting stop 24. It is not necessary to pull out the partition 22 completely. At this point, the medicinal materials on the partition 22 can be poured into a medicinal material bag or box, and then the partition 22 can be reset. The operation is simple and convenient.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
