Freeze Dry Technology

Freeze drying is the drying of frozen products in a vacuum below the triple point. The vacuum allows for a sublimation process facilitating the direct conversion of ice into vapor without any intermediate liquid stage.This results in an extremely gentle drying process preserving the product's active ingredient.Widely applied in the parmaceutical industry and food industry.

There are various drying methods, such as sun drying, boiling drying, drying, spray drying and vacuum drying, but common drying methods are usually carried out at temperatures above 0 ℃ or higher. The dried products generally have the problems of shrinking in size and hardening in texture. Most volatile components will be lost, some heat sensitive substances will be denatured and deactivated, and some substances will even be oxidized. Therefore, there is a great difference in properties between the dried products and those before drying.
