Address to All Industries
Freeze drying or lyophilization is a low temeprature dehydration method, gently dry products without ruin their physical structure and biological activities. So, freeze drying works well on almost all industries, and especially, it fits heat sensitive materials and perishable products.
The unique working process: Freezing the material and then reduce the surrounding pressure to allow the solid water sublime directly from solid phase to gas. During the process, most time, materials temperature are below zero. So, freeze drying has less impact on product properties, and freeze dried products do not need to be refrigerated or preserved with chemicals. They can be reconstituted quickly and easily by adding water.
In the past, only valuable pharmaceuticals and biological products adopt this technology, because freeze drying is costly. With the technological advancements, freeze drying costs are reduced and have been introduced to lots of industries.
Nowadays, thousands of products have been proved can be success freeze dried, and more and more are on the way. Here are some typically applications of freeze drying.
