Introduce
Vacuum freeze drying refers to the process of removing water or other solvents from frozen samples. During the whole drying process, sublimation prevents the sample from passing through the liquid state, and the sample is in a vacuum state, and the temperature is generally lower than -10°C. 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 temperatures, it can be used for some materials that are easily denatured at high temperatures, such as proteins, and can ensure that the properties of other compounds will not change.
After vacuum freeze-drying, most biological products such as tissues, tissue extracts, bacteria, vaccines and serum will become dry samples, and no enzyme changes and other biochemical reactions will occur during this process. Vacuum freeze drying is the gentlest process for preserving the biochemical properties of sensitive tissues or other tissues; it is also the best way to dry inorganic substances, such as nano-sized particles, because the surface area of the particles is almost unchanged.
Application
Gardening
A freeze dryer allows you to keep your home-grown fruits and vegetables fresh for years and years. Freeze drying at home is the very best way to preserve your garden harvest. It truly is the gardener’s best friend.
Emergency Preparedness
Freeze-dried food is perfect for emergency food supplies, bug out bags, 72-hour kits, and other survival packs. With a home freeze dryer, you will be prepared for any kind of emergency.
Outdoors
HFD-4 lets you freeze dry your own food at home to be used on your next hike, backpacking adventure, hunting trip, or camp out. It is lightweight, has less salt, and tastes better than anything else that will fit in your backpack.
Healthy Living
Buying freeze-dried food from a store is expensive. The food is full of salt and other preservatives and the limited choice means you buy meals you may not even enjoy eating. Freeze drying your own meals and produce is a great way to save when building your emergency food supply.
Pet Food
Everyone, even your pet, benefits from having a freeze dryer. You can easily feed your pets the healthy, preservative-free, home-prepared food they deserve and crave.
