Freeze-dried strawberries. Freeze drying, also known as lyophilization or cryodesiccation, is a low temperature dehydration process [1] that involves freezing the product and lowering pressure, thereby removing the ice by sublimation. [2]
IMA Life also offers freeze-drying technology: industrial, pilot and laboratory freeze dryers. IMA Life designs, manufactures, installs and services integrated systems predominantly for the pharmaceutical primary packaging market. It has been in the market of freeze dryer manufacturing for more than 50 years.
Promession is an idea of how to dispose human remains by way of freeze drying. The concept of promession was developed by Swedish biologist Susanne Wiigh-Mäsak, who derived the name from the Italian word for "promise" (promessa).

The freeze-drying process, he says, concentrates the flavor, and when the water rehydrating the bite-size scoops comes from your own mouth, well… “Something magical happens,” Freelon said.
Freeze drying or lyophilization is a drying method where the solvent is frozen prior to drying and is then sublimed, i.e., passed to the gas phase directly from the solid phase, below the melting point of the solvent. It is increasingly applied to dry foods, beyond its already classical pharmaceutical or medical applications.
Although freeze-drying is more expensive than traditional dehydration techniques, it also mitigates the change in flavor, texture, and nutritional value. In addition, another widely used industrial method of drying of food is convective hot air drying. Industrial hot air dryers are simple and easy to design, construct and maintain.
