Description

Technical Field

[0001] This utility model relates to the field of freeze-drying chamber technology, and in particular to a compact anti-condensation freeze-drying chamber structure. Background Technology

[0002] The freeze-drying chamber is the core component of a freeze dryer, used to remove moisture from materials through sublimation in a low-temperature, vacuum environment. It is widely used in food, pharmaceuticals, and biological products. Materials typically undergo three stages within the chamber: pre-freezing, sublimation, and secondary drying. Optimizing the freeze-drying chamber's structure, upgrading the temperature control system, and improving airflow and vacuum management can effectively reduce condensation during the drying process.

[0003] Existing freeze-drying chambers typically have multiple shelves that are fixed directly inside the chamber. The gap between adjacent shelves is fixed and cannot be flexibly adjusted according to the size of the items. This results in low space utilization and limited applicability of the freeze-drying chamber. Summary of the Invention
