How to choose the freeze drying chamber of freeze dryer

The freeze dryer is an equipment that freezes water-containing items in advance and then sublimates the water in a vacuum state to obtain dry items. Freeze-dried items are easy to store for a long time, and can be restored to their pre-freeze-dried state and maintain their original properties after adding water.

How to choose the freeze drying chamber of vacuum freeze dryer:

1. Capping tray freeze drying chamber: used for various vials, batch samples or freeze drying vials, pneumatic capping, adjustable sample heating and cooling;

2. Common freeze drying chamber: used for flask freeze drying, some vials and ampoules, small or large volume containers;

3. Multi-channel freeze drying chamber: used for small freeze drying flasks, vials and ampoules, most suitable for small volume containers;

4. Heating freeze drying chamber; used for batch samples or vials, most suitable for freeze drying of large volume samples;

5. Transparent capping freeze drying chamber: used for batch samples or vials, manual capping, heated freeze drying tray can accelerate sample freeze drying.

Freeze dryers can be divided into laboratory freeze dryers, pilot freeze dryers and production freeze dryers according to their uses. Vacuum freeze drying technology is widely used in pharmaceutical industry, food industry, material science and deep processing of agricultural and sideline products.
