Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine reference material processing technology, and in particular to a freeze-drying tray for traditional Chinese medicine reference materials. Background Technology

[0002] In order to quickly obtain the effective components from the concentrate obtained by distillation during the processing of traditional Chinese medicine reference standards, chromatographic purification and corresponding drying treatment are required. The commonly used drying method is oven drying, which can easily decompose some of the effective components. For this latter part, freeze drying is used. However, when using this method, because the concentrate is in a static state in the freeze-drying pan, the moisture at the bottom is difficult to evaporate, resulting in lower drying efficiency. Utility Model Content

[0003] This invention provides a freeze-drying tray for Chinese medicine reference standards, which overcomes the shortcomings of the prior art and solves the problem of low freeze-drying efficiency during the processing of Chinese medicine reference standards, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A freeze-drying tray for traditional Chinese medicine reference standards includes a rectangular tray with a raised rim at the top and multiple triangular prisms at the bottom. Multiple vent holes are formed on the two opposite sidewalls of each prism. A circular hole runs through the length of each prism, and an air inlet pipe is installed within the circular hole. Two rows of inner holes are formed on the air inlet pipe, with a one-to-one correspondence between the inner holes and the vent holes. By setting a triangular prism at the bottom of the rectangular tray and creating vent holes on it, the axial direction of these vent holes is perpendicular to the inclined surface of the triangular prism. When the inner holes and vent holes are connected, nitrogen gas is discharged into the concentrated liquid through the air inlet pipe, causing the concentrated liquid to agitate and thus improving freeze-drying efficiency. The inclined vent holes travel a longer distance when escaping through the concentrated liquid, thereby expanding the agitation range. The rotating air inlet pipe prevents the concentrated liquid from entering the air inlet pipe when liquid is injected into the rectangular tray.

[0006] Furthermore, one end of the circular hole is connected to an inner ring via a thread, and an end cap is formed on the outer end of the inner ring. The air intake pipe is located on the inner end of the inner ring. The other end of the circular hole is connected to an end ring via a thread, and a sealing ring is formed on the outer end of the end ring. The other end of the air intake pipe is formed to form a connecting pipe. The end ring and the sealing ring are fitted onto the connecting pipe. The outer diameter of the connecting pipe is smaller than the outer diameter of the air intake pipe. The connecting pipe passes through one side of the rectangular disc and extends out of the rectangular disc. The inner ring and the sealing ring and other components seal both ends of the circular hole.

[0007] Furthermore, multiple pairs of sealing protrusions are welded to one side of the rectangular disc. These sealing protrusions are distributed on the inner and outer sides of the rectangular disc. A conical protrusion is formed on the outer wall of the sealing protrusion, with the outer end of the conical protrusion being the smaller end. A retaining ring is fitted onto the conical protrusion, and a conical groove is formed on the inner side of the retaining ring. The conical protrusion passes through the conical groove, and a nut is provided on the outer side of the retaining ring. The nut is threaded onto the connecting pipe. The retaining ring and the sealing protrusion are fitted onto the connecting pipe. The sealing protrusion and the retaining ring improve the sealing effect between the connecting pipe and the rectangular disc. The sealing protrusion is welded to the inner and outer walls of the rectangular disc in a sealed manner.

[0008] Furthermore, the outer end of the connecting pipe is connected to an end sleeve via a thread. A swinging protrusion is formed on the outer periphery of the end sleeve. An oblong hole is opened on the swinging protrusion, and an action screw passes through the oblong hole. The outer end of the action screw is connected to a movable cross plate via a thread. End sleeve seats are respectively fitted on both ends of the movable cross plate. The end sleeve seats are welded to the rectangular disc. An end pull plate is welded to one end of the movable cross plate. A push screw is connected to the end pull plate via a thread. An end cap is provided on the outer end of the push screw. The inner end of the push screw abuts against the end sleeve seat. The movable cross plate can be moved to connect the exhaust port and the inner hole, so as to quickly open and close the intake connection of multiple intake pipes.

[0009] Furthermore, an end tube is formed on the outer end of the connecting pipe, the outer diameter of the end tube is smaller than the outer diameter of the connecting pipe, and a connecting sleeve is connected to the outer end of the end tube by a thread. An air inlet connecting pipe is formed on the outer end of the connecting sleeve and is connected to the nitrogen inlet pipe.

[0010] The advantages of the above technical solution are:

[0011] This invention improves freeze-drying efficiency by injecting gas to agitate the concentrated liquid during the freeze-drying of traditional Chinese medicine reference standards. Attached Figure Description

[0017] like Figures 1-4 As shown, a freeze-drying tray for Chinese medicine reference standards includes a rectangular tray body 1. The upper end of the rectangular tray body 1 is formed with a raised edge 10. The bottom of the rectangular tray body 1 is provided with a plurality of triangular prisms 2. A plurality of exhaust holes 21 are opened on the two opposite side walls of the triangular prisms 2. A circular hole is opened through the length of the triangular prism 2. An air inlet pipe 24 is provided in the circular hole. Two rows of inner holes 25 are opened on the air inlet pipe 24. The inner holes 25 and the exhaust holes 21 are in a one-to-one correspondence.

[0018] One end of the round hole is connected to an inner ring 22 by a thread. An end cap 23 is formed on the outer end of the inner ring 22. An air intake pipe 24 is located on the inner end of the inner ring 22. The other end of the round hole is connected to an end ring 27 by a thread. A sealing ring 28 is formed on the outer end of the end ring 27. A connecting pipe 26 is formed on the other end of the air intake pipe 24. The end ring 27 and the sealing ring 28 are fitted onto the connecting pipe 26. The outer diameter of the connecting pipe 26 is smaller than the outer diameter of the air intake pipe 24. The connecting pipe 26 passes through one side of the rectangular disc 1 and extends out of the rectangular disc 1. Multiple pairs of sealing protrusions 31 are welded to one side of the rectangular disc 1. The sealing protrusions 31 are distributed on the inner and outer sides of the rectangular disc 1. A conical protrusion is formed on the outer wall of the sealing protrusion 31. The outer end of the conical protrusion is the small end. A retaining ring 30 is fitted on the conical protrusion. A conical groove is formed on the inner side of the retaining ring 30. The conical protrusion passes through the conical groove. A nut 29 is provided on the outer side of the retaining ring 30. The nut 29 is threaded to the connecting pipe 26. The retaining ring 30 and the sealing protrusion 31 are fitted on the connecting pipe 26. The outer end of the connecting pipe 26 is threadedly connected to an end sleeve 32. A swinging protrusion 37 is formed on the outer periphery of the end sleeve 32. An oblong hole 38 is formed on the swinging protrusion 37, and an acting screw 39 passes through the oblong hole 38. A movable horizontal plate 40 is threadedly connected to the outer end of the acting screw 39. End sleeve seats 41 are fitted onto both ends of the movable horizontal plate 40. The end sleeve seats 41 are welded to the rectangular disc 1. An end pull plate 42 is welded to one end of the movable horizontal plate 40. A push screw 43 is threadedly connected to the end pull plate 42. An end cap 44 is provided on the outer end of the push screw 43, and the inner end of the push screw 43 abuts against the end sleeve seat 41. An end pipe 36 is formed on the outer end of the connecting pipe 26. The outer diameter of the end pipe 36 is smaller than the outer diameter of the connecting pipe 26. A connecting sleeve 34 is threadedly connected to the outer end of the end pipe 36. An air inlet connecting pipe 35 is formed on the outer end of the connecting sleeve 34.

[0019] In this embodiment, when injecting the concentrate, the moving horizontal plate 40 needs to be moved first. When the moving horizontal plate 40 moves, the acting screw 39 on it will act on the inner wall of the waist-shaped hole 38, thereby causing the swinging convex plate 37 to rotate. The rotation of the swinging convex plate 37 will drive the rotation of the air inlet pipe 24, thereby causing the inner hole 25 and its corresponding exhaust hole 21 to be misaligned. Then, the concentrate is injected into the rectangular plate 1, and the rectangular plates 1 are transferred one by one to the freeze-drying device. The inner end of the nitrogen connecting pipe is connected to the air inlet connecting pipe 35, and then nitrogen is introduced into the air inlet pipe 24.

[0020] The operator then moves the movable horizontal plate 40 again to make the swinging convex plate 37 swing vertically. At the same time, the extension length of the movable horizontal plate 40 is locked by turning the push screw 43. As the swinging convex plate 37 rotates, the inner hole 25 will connect with the exhaust hole 21. After the connection, nitrogen gas will pass through the connecting pipe 26, the air inlet pipe 24, the inner hole 25, and finally be discharged from the exhaust hole 21. The discharged gas will escape upward, carrying a large amount of moisture in the process, thereby improving the freeze-drying efficiency.

Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
