Freeze-drying, also known as lyophilization, is a process in which water in the form of ice under low pressure is removed from a material by sublimation. This process has found many applications for the production of high quality food and pharmaceuticals
Freeze-drying equipment freezes food or medicines during the dehydration process and removes moisture through sublimation, thereby maintaining the original characteristics of the product, such as original flavor, texture, color and nutritional content.
