Description

Technical Field

[0001] This utility model relates to the technical field of dryers, and in particular to a pharmaceutical freeze dryer. Background Technology

[0002] Freeze-drying utilizes the principle of ice crystal sublimation. In a high vacuum environment, the moisture in frozen food materials is sublimated directly from the ice solid to vapor without melting the ice. In general, vacuum drying of materials involves converting the moisture in the liquid state to the gaseous state to dry the food. Therefore, freeze-drying is also known as freeze sublimation drying.

[0003] In the use of freeze dryers, drying racks are required as containers to hold pharmaceuticals and other substances that need to be freeze-dried. During transfer or freeze-drying, the trays and drying racks are prone to shaking, which can cause the pharmaceuticals to tip over.

[0004] To improve the stability of the drying rack, the existing structure needs to be modified to enhance its performance. Utility Model Content
