Food Freeze Dryer By Vacline Technologies

We have carved a niche amongst the most dominant names in this domain, engaged in importing, manufacturing, distributing, trading and supplying an excellent quality spectrum of Food Freeze Dryer in Chennai, Tamil Nadu, India. Freeze drying was developed during World War II to keep the vaccines for the wounded from spoiling due to lack of refrigeration system while transporting to the war zone. It has been refined and used extensively by NASA to make freeze dried food for astronauts under space program.

The outstanding advantage of the freeze dried food is its long shelf life. When properly stored, many freeze dried food can be eaten 15 to 25 years after they have been prepared. The fooda s flavor and nutritional value is almost as good as it was the day it was dried.
During the freeze drying process, the food is frozen at -45A C to -50A C. Once the food is frozen, a powerful vacuum should be created around the food. Then the food is gradually warmed, even though it continuous to stay frozen.

That is why vacuum environment is very important. In that environment, water sublimates (evaporates) out of the food at just -20A C. Water cannot exist as liquid in vacuum and, as it warms, is drawn out of the solid frozen food as gas. When done properly, freeze drying virtually removes 100% of the water from the food.
