Electric heating freeze dryer
Vacuum freeze-drying technology, also called aerospace freeze-drying technology, refers to the use of the principle of sublimation in a low-temperature vacuum state of about minus 30-50 degrees, so that the moisture in pre-frozen food can be directly sublimated into water vapor in the ice state without melting the ice. A technique that removes and thereby dries food. It was first used to solve the nutrition problem of astronauts' food preservation boxes during their work in space.
Compared with techniques such as air drying and dehydration, the biggest feature of freeze-dried food is that it retains the color, aroma, taste, shape and nutrients of the original food.
