The bottom of the drying chamber 1 is equipped with the base 3.

[0030] The inner wall of the freeze-drying chamber 4 is equipped with a support frame 6, the top of the support frame 6 is equipped with an electric heating tube 7, the two sides of the top of the support frame 6 are equipped with support blocks 8, the top of the support blocks 8 is equipped with a material rack 9, the material rack 9 has several storage slots 10, the inner wall of the storage slots 10 is movably connected with a storage box 11, the inner wall of the freeze-drying chamber 4 is connected to a freezer 34 through a pipe, and the bottom of the freezer 34 is installed on one side of the outer wall of the drying chamber 1.

[0031] Several fixing plates 12 are installed in the middle of both sides of the material rack 9. The top of the fixing plate 12 has a vibration component, which is used to continuously vibrate the storage box 11.

[0032] Furthermore, the drying chamber 1 is divided into a freeze-drying chamber 4 and a water-capturing chamber 5 by the partition 2, which realizes the rapid freeze-drying and effective separation of moisture from the barley. The support frame 6 and electric heating tube 7 set in the freeze-drying chamber 4 provide a uniform heating environment. The storage slots 10 and storage boxes 11 on the material rack 9 not only facilitate the placement and removal of barley, but also continuously vibrate the storage boxes 11 through the vibration component on the top of the fixed plate 12, which effectively promotes the shedding of ice crystals on the surface of the barley and the diffusion of internal moisture. At the same time, it can prevent caking during drying, thereby improving drying efficiency and drying quality.

[0033] Example 2: Please refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 According to one embodiment of the present invention, the vibration assembly includes a limiting sleeve 13, the bottom of which is installed at the front end of the top of the fixing plate 12.

[0035] Furthermore, by ensuring a stable connection between the limiting sleeve 13 and the fixing plate 12, the stable operation of the vibration assembly is ensured. The drive shaft 16 inside the fixing box 14 rotates under the drive of the servo motor 18, causing the cam 17 to periodically contact and push the push block 19, thereby causing the vibrating block 20 to reciprocate against the outer wall of the storage box 11. This effectively promotes the turning of the barley inside the storage box 11 and the shedding of surface ice crystals. The vibration pad 21 at one end of the vibrating block 20 not only enhances the vibration transmission efficiency but also protects the storage box 11 from direct impact, ensuring the durability of the equipment. At the same time, the setting of the first pressure spring 22 not only provides the restoring force for the vibrating block 20 but also increases the gentleness and uniformity of the vibration, thereby preventing the barley from being damaged by excessive vibration.

[0036] Example 3: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment of this utility model, a first limiting groove 23 is provided on both sides of the front end of the outer wall of the storage box 11. A second pressure spring 24 is movably connected inside the first limiting groove 23. One end of the second pressure spring 24 is movably connected to a first limiting block 25. The tail end of the outer wall of the first limiting block 25 is movably connected to the inside of the first limiting groove 23. The front end of the outer wall of the first limiting block 25 is movably connected to the inside of the cylindrical limiting hole 26. The cylindrical limiting hole 26 is opened at the front end of the inner wall of the storage groove 10. A sliding groove 27 is provided on both sides of one end of the storage box 11. The other end of the sliding groove 27 is opened on the inner wall of the first limiting groove 23. A slider 28 is movably connected to the inner wall of the sliding groove 27.

[0037] The storage box 11 has two second limiting grooves 29 on both sides of the outer wall. A third pressure spring 30 is movably connected inside the second limiting groove 29. One end of the third pressure spring 30 is movably connected to a second limiting block 31. The tail end of the outer wall of the second limiting block 31 is movably connected to the inside of the second limiting groove 29. The front end of the outer wall of the second limiting block 31 is movably connected to the inside of the semi-circular limiting groove 32. The semi-circular limiting groove 32 is opened at the tail end of the inner wall of the storage slot 10.

[0038] Furthermore, through the combined use of the first limiting groove 23 with the second pressure spring 24 and the first limiting block 25, as well as the limiting effect of the cylindrical limiting hole 26, the storage box 11 is stably installed and easily disassembled in the storage groove 10, ensuring the stability of the barley during the drying process. The sliding groove 27 and the slider 28 facilitate the user to quickly replace or clean the storage box 11 as needed. In addition, the setting of the second limiting groove 29 with the third pressure spring 30, the second limiting block 31 and the semi-circular limiting groove 32 helps to provide additional stability and safety for the storage box 11.

The vacuum pumps 35 are installed inside the water-catching chamber 5 through a pipe penetrating the outer wall of the drying box 1.

[0040] A water-catching pipe 36 is installed through the middle of one side of the partition 2, and a solenoid valve 37 is installed at one end of the water-catching pipe 36.

[0041] Furthermore, the arrangement of the placement rack 33, vacuum pump 35, and water-collecting chamber 5 enhances the vacuum level of the water-collecting chamber 5, thereby accelerating the sublimation and collection of moisture during the freeze-drying process of highland barley, significantly improving drying efficiency and the thoroughness of moisture removal. At the same time, the design of the water-collecting pipe 36 installed through the middle of the partition 2 and the solenoid valve 37 at one end not only facilitates the timely discharge of water accumulated in the water-collecting chamber 5, but also enables flexible adjustment and precise management of the moisture discharge process through the precise control of the solenoid valve 37, further ensuring the quality and stability of highland barley drying.

[0042] The working principle involves dividing the drying chamber 1 into a freeze-drying chamber 4 and a water-collecting chamber 5 via a partition 2, achieving rapid freeze-drying and effective moisture separation of the barley. The support frame 6 and electric heating tube 7 within the freeze-drying chamber 4 provide a uniform heating environment. The storage slots 10 and storage boxes 11 on the material rack 9 not only facilitate the placement and removal of the barley but also, through the continuous vibration of the storage boxes 11 via the vibration component on the top of the fixed plate 12, effectively promote the shedding of ice crystals from the barley surface and the diffusion of internal moisture. This also prevents caking during drying, thereby improving drying efficiency and quality. The secure connection between the sleeve 13 and the fixed plate 12 ensures the stable operation of the vibration assembly. The drive shaft 16 inside the fixed box 14 rotates under the drive of the servo motor 18, causing the cam 17 to periodically contact and push the push block 19. This causes the vibrating block 20 to reciprocate against the outer wall of the storage box 11, effectively promoting the turning of the barley inside the storage box 11 and the shedding of surface ice crystals. The vibration pad 21 at one end of the vibrating block 20 not only enhances the vibration transmission efficiency but also protects the storage box 11 from direct impact, ensuring the durability of the equipment. Simultaneously, the first pressure spring 22 provides not only a return force for the vibrating block 20 but also... The combined force also increases the gentleness and uniformity of vibration, thus preventing damage to the barley due to excessive vibration. Through the coordinated use of the first limiting groove 23, the second pressure spring 24, the first limiting block 25, and the limiting effect of the cylindrical limiting hole 26, the storage box 11 is stably installed and easily disassembled within the storage groove 10, ensuring the stability of the barley during the drying process. Furthermore, the sliding groove 27 and the slider 28 allow users to quickly replace or clean the storage box 11 as needed. In addition, the second limiting groove 29, the third pressure spring 30, the second limiting block 31, and the semi-circular limiting groove 32... The storage box 11 provides additional stability and safety. The placement of the rack 33, vacuum pump 35, and water-collecting chamber 5 enhances the vacuum level of the water-collecting chamber 5, thereby accelerating the sublimation and collection of moisture during the freeze-drying process of highland barley. This significantly improves drying efficiency and the thoroughness of moisture removal. At the same time, the design of the water-collecting pipe 36 installed through the middle of the partition 2 and the solenoid valve 37 at one end not only facilitates the timely discharge of water accumulated in the water-collecting chamber 5, but also enables flexible adjustment and precise management of the moisture discharge process through the precise control of the solenoid valve 37, further ensuring the quality and stability of highland barley drying.
