A pair of limiting rings are provided on the connecting tube, and the limiting rings are located on the inner and outer sides of the lower end cap. A plurality of notches are provided at the inner end of the connecting tube, and the inner end of the connecting tube acts on the sealing ball. Through a detachable and fixed concave tube, one is that when nitrogen and other gases enter the lyophilized material through the air holes thereon, the lyophilized material is stirred by passing the gas, thereby improving the lyophilization efficiency of the lyophilized material. The second is that the detachable connection method facilitates the cleaning of the tray. The provided sealing ball can prevent the lyophilized material from flowing outward through the connecting tube, and the connecting tube can lift the sealing ball, thereby facilitating the introduction of nitrogen, and in order to prevent the connecting tube from lifting the sealing ball when the lyophilized tray is placed, a corresponding lower end cap is provided, and the lower end cap can actively control the extension and withdrawal of the connecting tube.

[0006] Furthermore, the tray has a rectangular structure, which is convenient for storing freeze-dried materials.
