In a freeze dryer, the drying chamber have 2 shape: rectangular and cylindrical. Here are the main differences between:
- Rectangular drying chamber have a higher space using rate than cylindrical drying chamber.
- Rectangular chamber have a better temperature uniformity than cylindrical drying chamber.
- Rectangular chamber mostly apply in pharmaceutical, biological area, where precise temperature control is needed.
- Cylindrical drying chamber mostly apply in food area.
- Rectangular drying chamber have a complex technical process and need longer time to remove internal stress. Cylindrical drying chamber is easy to form.
- Rectangular drying chamber cost higher than cylindrical drying chamber.
