[0002] Capped freeze dryers are widely used in the drying process of biological drugs. Biological drugs are generally filled in vials with rubber stoppers. Capped freeze dryers are used to freeze-dry the filled vials, evaporate the water in the mixture in the vials, and complete the stoppering and sealing of the vials, which can effectively prevent the drugs from being contaminated. When the capped freeze dryer is drying the materials inside the vials, the vials are usually placed on a tray for freeze drying.

[0010] By adopting the above technical solution, the position of the adjustment block and the rubber clamping pad is adjusted by utilizing the elastic force of the adjustment spring, so that the rubber clamping pad fits the outer wall of the vials of different sizes within a certain range, thereby ensuring the clamping effect of the clamping unit.

[0011] As a preferred technical solution of the present application, four adjustment grooves and four clamping units are distributed around the plurality of placement grooves, and the four adjustment grooves and clamping units are evenly distributed in a circular array with respect to the placement grooves.
