[0002] A freeze dryer is a device used in the pharmaceutical and food industries to freeze-dry drugs and foods. It first freezes the items (products) to be freeze-dried at low temperatures, and then, under vacuum conditions, uses vacuum sublimation and analytical adsorption to reduce the moisture content of the products to a level that cannot sustain biological and chemical reactions for a long time. The tray is an essential tool for transporting and holding items to be freeze-dried. It is used to place the items to be freeze-dried on the partition of the freeze dryer for freezing.

[0003] When the existing pallet is being transported, the freeze-dried bottle is prone to collide with the bottom of the inner cavity of the groove, which can easily damage the freeze-dried bottle and reduce its service life. For this reason, we propose a freeze-drying machine pallet mechanism for biopharmaceuticals. Utility Model Content
