Improvements in freeze-drying processes and equipment have been an ongoing challenge. The design of devices for efficient drying in as sterile conditions as possible has led to the development of specific equipment solutions for laboratory and industrial applications.
Vacuum freeze drying technology, referred to as freeze drying, also known as sublimation drying. Widely used in pharmaceuticals, biological products, chemical and food industries.
requires the freeze dryer chamber to be a certified pressure vessel, rated at 2 atmospheres at 131oC. Another method of disinfection is to use hydrogen peroxide. Pressurized steam sterilization adds significant complexity and cost to freeze dryers. On the other hand, the hydrogen peroxide method generally reduces costs.
