Vacuum freeze drying is the removal of water or other solvents from the frozen samples. During the whole drying process, the sample is in liquid state and the temperature is generally lower than -10. The purpose of vacuum freeze drying is to restore the original characteristics of the sample after rehydration.
Because the drying process is carried out at low temperature, it can be used for some materials such as proteins, which are easy to be denatured at high temperature, and can ensure that the properties of other compounds will not change.
A freeze dryer machine is simply an appliance that removes nearly all the moisture from foods.
There are several important benefits to removing moisture from food, the primary benefit being an incredibly long shelf life.
And when it comes to food preservation, and reduced food waste, it's all about improved shelf life.
Home freeze dryer is a small vacuum freeze dryer.It is suitable for small scale freeze drying at home and online stores.Home freeze dryer is widely adapted to the freeze drying of fruits, meats, vegetables, Chinese medicinal materials, health products and other products.
One that involves 3 main steps:
* Freezing
* Lowering pressure
* Removing the moisture through sublimation
