[0015] Example: Please refer to Figure 1-3A freeze-drying device for organic intermediate raw materials comprises a drying cylinder 1 and a plurality of trays 2. The drying cylinder 1 is mounted on a bracket 12. The plurality of trays 2 are arranged inside the drying cylinder 1. The raw materials are placed on the trays 2. The plurality of trays 2 are mounted on a supporting disk 3. Two supporting disks 3 are provided, and the two supporting disks 3 are respectively arranged at the two ends of the tray 2; the tray 2 and the supporting disk 3 are detachably connected. Specifically, a square connecting rod is provided at both ends of each tray 2. The supporting disk 3 is provided with a square groove corresponding to the connecting rod. The connecting rod is inserted into the square groove, so that the tray 2 is fixed on the supporting disk 3, so that the tray 2 can be quickly assembled; the plurality of trays 2 are divided into Layer distribution, preferably, the tray 2 of this embodiment is arranged in four layers, and there is a certain distance between two adjacent layers, which can facilitate the placement of raw materials on the tray 2; the first and fourth layers are each provided with a tray 2, and the second and third layers are respectively provided with two trays 2, and the trays 2 of the second and third layers are staggered with the tray 2 of the first layer, that is, at least half of the area of ​​the tray 2 of the second layer will not be blocked by the tray 2 of the first layer, on the one hand, the space utilization rate is improved, and on the other hand, it is also convenient to take and put raw materials; a take-up port 8 is provided at the end of the drying cylinder 1, and a sealing cover 9 is provided at the take-up port 8, and the sealing cover 9 is hinged to the drying cylinder 1; the supporting plate 3 is connected to the drying cylinder 1; A support rod 4 is connected to the support rod 4, and a slide bar 5 is connected to the support rod 4. The inner wall of the drying cylinder 1 is provided with a slide rail 6 adapted to the slide bar 5.
