Description

Technical Field

[0001] The utility model relates to the field of vacuum drying chambers, in particular to freeze-drying equipment for preparing freeze-dried cypress bark powder. Background Art

[0002] The processing of concentrated cypress bark powder involves 1. Raw material collection and pretreatment: High-quality, mature cypress bark is selected as the raw material. The bark is cleaned to remove impurities and surface dirt. 2. Pulverization: The pretreated cypress bark is pulverized into smaller particles to increase the efficiency of subsequent extraction. 3. Extraction: The pulverized cypress bark is extracted using an appropriate solvent (such as ethanol or water). This process is typically carried out under specific temperature and time conditions to fully dissolve the active ingredients. 4. Filtration and separation: The extract is filtered to remove solid impurities. The active ingredients are then separated from other components in the extract by centrifugation or other separation methods. 5. Concentration: The separated extract is concentrated to increase the concentration of the active ingredients. 6. Freeze-drying: The concentrated liquid is placed in a freeze-drying machine. It is first rapidly frozen to a low temperature and then heated under vacuum to cause the water in it to sublime directly from the solid state to the gas phase, resulting in a dry powder, namely cypress bark freeze-dried powder.

[0003] In the prior art, multiple trays containing frozen aqueous concentrate need to be placed in a vacuum tank. Since the vacuum tank is relatively long, a pull rod needs to be used to assist in removing the trays, which makes the removal process inconvenient. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 5 The utility model discloses a freeze-drying device for preparing freeze-dried powder of cypress shell, comprising a vacuum tank 1, an inner wall of the vacuum tank 1 is provided with a heating support plate 6 through a vertical rod 5, and the heating support plate 6 is in an inclined state, and the lower end edge of the heating support plate 6 is located at the opening position of the vacuum tank 1, the inner cavity of the heating support plate 6 is a hollow structure, and the interior of the heating support plate 6 is connected to a blocking mechanism for sliding up and down near the lower end, and a lever mechanism connected to the blocking mechanism is installed on the outer side of the heating support plate 6; the blocking mechanism comprises a limit plate 7 located inside the vacuum tank 1 and passing through the upper part of the heating support plate 6, and the limit plate 7 has a pressure inclined surface 8 at one end above the heating support plate 6, and the pressure inclined surface 8 is a low point edge close to the opening edge of the vacuum tank 1, and the bottom end of the limit plate 7 is integrally formed with a protrusion, the width of the protrusion is greater than the width of the limit plate 7, and a spring 15 is installed at the bottom end of the protrusion, and the bottom end of the spring 15 is fixedly connected to the bottom end of the inner wall of the heating support plate 6.

[0022] In this embodiment, the frozen cypress bark concentrate is placed in a vacuum tank 1 and positioned above a heating support plate 6. The tank lid is then closed and the vacuum pump is activated to extract the gas from the vacuum tank 1. As the gas pressure decreases, the boiling point of the solid water decreases. After vacuuming, the solid water in the concentrate is directly sublimated and vaporized by heating.

[0023] When the tray containing the solidified concentrated liquid is added to the heating support plate 6, the tray is placed above the heating support plate 6 and pushed to move along the top surface of the heating support plate 6. When the tray contacts and squeezes the pressure inclined surface 8, the limit plate 7 is forced to move downward. When the tray and the limit plate 7 are misaligned, the limit plate 7 is reset and the vertical surface of the limit plate 7 contacts. At this time, the tray containing the solidified concentrated liquid is limited.

[0024] After the vacuum drying is completed, the limit plate 7 is retracted by lifting the lever mechanism. At this time, the tray at the front end can slide down smoothly, making it easy to take out the tray containing the concentrated liquid.

[0025] Please refer to Figure 3 and Figure 5 The lever mechanism includes a rotating shaft 12 rotatably connected to the outside of the heating support plate 6, and a lever 11 is fixedly connected to the outer wall of the rotating shaft 12. The lever 11 is divided into a long arm and a short arm with the rotating shaft 12 as the center. One end of the limit plate 7 is fixedly connected to a synchronization rod 16 that passes through the outside of the heating support plate 6. A vertical groove 9 is provided on the side plate of the heating support plate 6 for the synchronization rod 16 to slide up and down. One end of the synchronization rod 16 is fixedly connected to a force rod 10, and the force rod 10 is located below the short arm.

[0026] In this embodiment: after the vacuum drying is completed, when taking out the tray containing the concentrated liquid, the long arm part of the lever 11 is lifted up, and the lever 11 rotates around the rotating shaft 12 as the axis. At this time, the short arm of the lever 11 rotates downward, pressing down the force-bearing rod 10. At this time, the force-bearing rod 10 drives the synchronization rod 16 to slide downward, and the synchronization rod 16 slides downward along the vertical slot 9. At the same time, the limit plate 7 slides downward, and the limit on the front tray is cancelled.

[0027] Please refer to Figure 3 The top of the inner wall of the heating support plate 6 is installed with a serpentine electric heating tube 13 through a fixing member 14. The electric heating tube 13 is electrically connected to an external power supply through a wire. Wire holes are opened on the heating support plate 6 and the vacuum tank 1 for the wires to pass through, and the inner wall of the wire hole is provided with a rubber seal to improve the sealing performance.

[0028] In this embodiment, the electric heating tube 13 is activated by a switch to heat the tank body. At this time, the solid water body is directly converted from solid to gaseous under vacuum state, thereby achieving a vacuum drying effect.

[0029] Please refer to Figure 1 The interior of the vacuum tank 1 is connected to the input end of the vacuum pump through a vacuum tube 2. The outer wall of the vacuum tube 2 is connected to a steam pipe 3. The steam pipe 3 is connected to the input end of the vacuum pump. A one-way valve 4 is installed on the output end of the vacuum tube 2 and the steam pipe 3.

[0030] In this embodiment: after the tank lid is closed, the vacuum pump is started, and the vacuum pump extracts the gas in the vacuum tank 1 through the vacuum tube 2 to form a vacuum state. The one-way valve 4 on the vacuum tube 2 is used to prevent external gas from entering the vacuum tank 1. After the solid water body sublimates, the vacuum pump is started. Under the action of negative pressure, the one-way valve 4 on the steam pipe 3 is opened, and the gaseous water is sucked in and discharged.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
