[0018] The present invention will be further described below with reference to the embodiments.

[0019] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention; the conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0020] Please see Figures 1-4 This utility model provides a detachable drying rack for a vacuum freeze dryer, including a vacuum freeze dryer body 1 and a side frame assembly. The upper and lower ends of the adjacent sides of the two side frame assemblies are rotatably connected to rotating frames 7. The adjacent ends of the two rotating frames 7 at the same end are rotatably connected. A plurality of placement frames 9 are slidably connected between the adjacent ends of the two side frame assemblies. The placement frame 9 includes a fixing strip 10 fixedly connected to both sides. The fixing strip 10 is slidably connected to the inside of the side frame assembly. The side frame assembly includes a locking strip 3 slidably connected to the inside of the side rail 2. The two ends of the locking strip 3 away from the corresponding side rail 2 are fixedly connected to mounting frames 4. The upper and lower ends of the two adjacent sides of the mounting frames 4 on the same side are fixedly connected to connecting rods 5. A plurality of slots 6 adapted to the fixing strip 10 are opened on the side of the mounting frame 4 away from the corresponding locking strip 3. The fixing strip 10 is slidably connected to the inside of the mounting frame 4 through the slots 6. A baffle 12 is fixedly connected to one side of the side frame assembly. One end of the fixing strip 10 is tightly fitted to the baffle 12.

[0021] Pull the two folded side frame components to the sides to allow the rotating frames 7 on both sides to rotate and unfold until the rotating frames 7 on both sides are 180 degrees apart, so that the side frame components and rotating frames 7 form a cuboid structure. Select an appropriate number of placement frames 9 and slide the fixing strips 10 of the placement frames 9 from the end away from the baffle 12 into the slots 6 on the inside of the mounting frame 4 until they abut against the baffle 12. Insert all placement frames 9 as needed and ensure the spacing between them.

[0022] When the drying rack is not needed, the operator can pull out the placement frame 9 and use the rotation function of the rotating frame 7 to fold up the side frame components on both sides. In this way, the storage volume of the drying rack is significantly reduced, thus saving more space during carrying and transportation, reducing transportation costs and carrying difficulty. This foldable design not only improves the flexibility of the drying rack, but also makes it adaptable to different usage scenarios.

[0023] The slots 6 are evenly distributed on the inner side of the mounting frame 4. This even distribution design provides a basis for the orderly arrangement and fixation of the placement frames 9. The clever cooperation between the fixing strip 10 and the slots 6 allows multiple placement frames 9 to be quickly and stably inserted and fixed between the two side frame components. This structure not only ensures the stability of the placement frames 9 during the drying process, but also allows the operator to flexibly adjust the distance between multiple placement frames 9 according to different material types, quantities and drying requirements. This allows the device to make full use of the internal space of the vacuum freeze dryer body 1, avoids space waste, and also improves drying efficiency.

[0024] Please see Figures 1-4 Both ends of the inner side of the vacuum freeze dryer body 1 are fixedly connected to the side rails 2. The side frame assembly is slidably connected to the two side rails 2 at the ends close to each other. One end of the clamping strip 3 is trapezoidal. The side rail 2 has a trapezoidal groove adapted to the clamping strip 3. The clamping grooves 6 are evenly distributed from top to bottom on the end of the mounting frame 4 away from the corresponding clamping strip 3. The rotating frame 7 includes a reinforcing rod 8 fixedly connected to the inner side, which is located at the end close to the side frame assembly. The placement frame 9 includes a bottom plate 11 fixedly connected to the bottom end. The bottom plate 11 has several holes on the inner side. A movable door 13 is hinged to one side of the vacuum freeze dryer body 1.

[0025] Place the items to be dried into the respective placement frames 9, open the movable door 13 on one side of the vacuum freeze dryer body 1, and place the assembled drying rack into the vacuum freeze dryer body 1 so that the locking strips 3 on both sides slide into the corresponding side rails 2 until they are in place. Then close the movable door 13. When the vacuum freeze dryer body 1 is working, a low-temperature vacuum environment will be generated inside it for subsequent drying. After the items are dried, open the movable door 13, slide the side rack assembly out from the side rails 2, remove the drying rack, and you can take off the dried items.

[0026] The sliding fit design between the side rail 2 and the clamping strip 3 makes it possible to quickly disassemble and assemble the side frame assembly and its inner parts. This design allows operators to easily remove the entire drying rack from the vacuum freeze dryer body 1, thus facilitating cleaning and replacement. This improvement not only saves time and labor costs, but also effectively improves the overall working efficiency of the device.

[0027] The working principle and usage process of this utility model are as follows: Pull out the two folded side frame components to both sides, so that the rotating frames 7 on both sides rotate and unfold until the rotating frames 7 on both sides are 180 degrees apart, so that the side frame components and rotating frames 7 form a cuboid structure. Select an appropriate number of placement frames 9, slide the fixing strips 10 of the placement frames 9 from the end away from the baffle 12 and insert them into the slots 6 on the inner side of the mounting frame 4 until they abut against the baffle 12. Insert all placement frames 9 as needed, ensuring the spacing between them. Place the items to be dried into each placement frame 9. Open the movable door 13 on one side of the vacuum freeze dryer body 1, and place the assembled drying rack into the vacuum freeze dryer body 1, so that the locking strips 3 on both sides slide into the inner side of the corresponding side rail 2 until they slide into place. Then close the movable door 13. When the vacuum freeze dryer body 1 is working, a low-temperature vacuum environment is generated inside it for subsequent drying. After the items are dried, open the movable door 13, slide the side frame components out from the side rail 2, take out the drying rack, and then remove the dried items.

[0028] In the above scheme, it should be noted that: the vacuum freeze dryer body 1 in this application is model YS-HFD-10, and the vacuum freeze dryer body 1 is a product of the prior art. Its vacuum freeze drying principle is a publicly disclosed technical means. At the same time, the innovation and improvement of this application do not involve the vacuum freeze drying principle, so it will not be described in detail.

[0029] 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 of the present invention, the scope of which is defined by the appended claims and their equivalents.
