A storage tray 3 is provided on one side of the fixed tray 1, and the storage tray 3 is fixedly connected to the inside of the fixed tray 1, and the storage tray 3 extends to the outside of the fixed tray 1 through the reserved hole 2;

[0029] On both sides inside the storage tray 3, a plurality of equally spaced positioning strips 6 are fixedly connected, and the plurality of equally spaced positioning strips 6 are symmetrically distributed inside the storage tray 3. A plurality of equally spaced partition plates 7 are arranged inside the storage tray 3, and positioning grooves 8 are symmetrically arranged on both sides of the partition plate 7, and the inside of the positioning groove 8 is slidably connected to the outside of the positioning strip 6. The partition plate 7 is fixed inside the storage tray 3 through the connection between the positioning groove 8 and the positioning strip 6.

[0031] The partition plate 7 is set as a hollow structure, and a plurality of evenly distributed openings are arranged inside the partition plate 7, and a handle 9 is fixedly connected to the middle of the top of the partition plate 7.

[0032] A plurality of equally spaced second ventilation holes 10 are arranged on the outside of the fixed tray 1, and the plurality of equally spaced second ventilation holes 10 correspond to the first ventilation holes 4 on the outside of the storage tray 3 one by one, and the plurality of equally spaced second ventilation holes 10 make the fixed tray 1 form a hollow structure.

[0033] Heightening plates 11 extending upward are arranged at the four corners of the fixed tray 1, and a reinforcing connecting rod 12 distributed in a ring shape is fixedly connected to the outside of the four fixed trays 1, and an opening that can be grasped is formed between the reinforcing connecting rod 12 and the side of the fixed tray 1.

[0034] An extension plate 13 is fixedly connected to the outside of the top of the reinforcing connecting rod 12, and the top of the extension plate 13 is higher than the top of the heightening plate 11, and an installation groove is formed between the inner side of the extension plate 13 and the top of the heightening plate 11.

[0035] The installation grooves formed between the inner side of the extension plate 13 and the top of the reinforcement connecting rod 12 are distributed on the tops of the four heightening plates 11, and the slots on the tops of the four heightening plates 11 cooperate with each other to form an annular structure.

[0036] Embodiment 2: On the basis of Embodiment 1, the specific working principle is as follows:

[0037] The freeze-drying tray with a positioning structure divides the inside of the storage tray 3 through the partition plate 7 to form compartments of different sizes, so as to place freeze-dried samples in the compartments inside the multiple storage trays 3. By pulling the handle 9, the partition plate 7 is driven to move inside the storage tray 3. During the movement, the partition plate 7 slides stably along the positioning strip 6 through the positioning grooves 8 on both sides thereof, enabling the quick installation and disassembly of the partition plate 7 inside the storage tray 3, and further enabling the quick adjustment of the position of the partition plate 7 inside the storage tray 3, so that the interval space inside the storage tray 3 can be flexibly adjusted to adapt to freeze-dried samples of different sizes. According to the actual size of the freeze-dried samples, the position of the partition plate 7 inside the storage tray 3 is adjusted, and then the size of the interval space inside the storage tray 3 is adjusted to ensure that freeze-dried samples of various sizes can be placed in the compartments matching their sizes, preventing the freeze-dried samples from moving inside the storage tray 3, thereby realizing the precise positioning of the freeze-dried samples inside the storage tray 3;

[0038] During the processing of the freeze-dried samples, the storage tray 3 forms a drawer structure inside the fixed tray 1 through a sliding mechanism. Before the start of freeze-drying processing, the storage tray 3 is driven to slide inside the fixed tray 1 by operating the handle 5 until the storage tray 3 completely moves out of the fixed tray 1. Subsequently, the samples to be freeze-dried are placed inside the storage tray 3, and then it is slid back into the fixed tray 1. When the freeze-drying process is completed, the storage tray 3 is pulled out of the fixed tray 1 again by pulling the handle 5, so as to facilitate the taking out and collection of the freeze-dried samples that have been completed, realizing the convenient addition and efficient collection of the freeze-dried samples inside the freeze-dryer;

[0039] Multiple fixed trays 1 can be stacked on top of each other. The installation grooves formed between the top of the heightening plate 11 and the inner side of the extension plate 13 can coordinate with each other. When the fixed trays 1 are stacked, the bottom edge of the fixed tray 1 at the top will be precisely engaged with the inside of the installation groove of the fixed tray 1 at the bottom, ensuring that the two stacked fixed trays 1 can form a stable structure. By this way of mutual stacking, the integration degree of the fixed trays 1 inside the freeze-dryer can be effectively improved, thereby reducing its floor area and realizing the optimized utilization of the internal space of the freeze-dryer;

[0040] The reinforced connecting rod 12 and the edge of the fixed tray 1 are designed with apertures for grasping, allowing the user to lift the fixed tray 1 as a whole by holding the reinforced connecting rods 12 on both sides of the fixed tray 1, thereby realizing the handling operation of multiple stacked fixed trays 1. This not only improves the handling convenience of the fixed tray 1, ensures the stability and safety of the internal freeze-dried samples during handling, but also enables multiple fixed trays 1 to be stacked on top of each other to achieve batch storage of the freeze-dried samples, reducing the handling steps and preventing the freeze-dried samples from being broken during the handling and movement process.
