Main applications:

vacuum freeze drying equipment is the most advanced dehydration technology used in the food industry to produce superier quality LD food products.

The LD food products have been widely used in the poducts such as LD fruits for leisure food, LD vegetables for high end convenient food, ingredients, high grade instant coffee, milk powder, convenient soap, high nutrition healthy food, herbs, military and aerospace food products and etc.

Working principle of vacuum freeze dryer:

Instead of traditional vaporization dehydration method, the vacuum freeze drying technology is dehydrate products by sublimation directly from ice to vapor. During the Freeze drying process, the materials will be frozen to -18°c, then move into the vacuum drying tank for dehydration, automatic control system will set the vacuum and heating temperature according to the freeze drying cirve of each products to maintain the proper circumstances for LD processing. The materials stay in frozen status during the drying process and water vapor will be condensed on the surface of cold trap coils to absort the water out from the materials.

Advantages of vacuum freeze dryer:

Comparing with traditional hot air dehydrated products, the Freeze Dry products have unique characters and advantages. The most clear difference is the appearance of the final products, the LD products will keep the same shape and color as they were frozen, it won't become shrink or darken after drying. Further inside quality of the products, due to low temperature drying technology, the nutritons within the products have been preserved at the highest level. And due to the sublimation process had minimum damage for the material structure and cellular tissues, the rehydration rate is extremely high. After the rehydration, the products will be with very close charaters with the fresh materials. And many other advantages due to the low moisture content after freeze drying. The products can be stored for a very long period. Comparing with frozen products, it is much easier and cost efficient for transportation and storage.

Basic working principle of High quality vegetable lyophilization / fruit vacuum freeze drying machine / meat freeze dryer is to use steam or hot water or thermal oil as heat sources,use radiator to generate heat.Water vaporizes very fast when it's boiled.Under ordinary pressure,water starts to boil at about 100℃,but under vacuum condition, vaporization tends to occur when partial pressure is much higher,and boiling point is blow 100℃.For example,water starts to boil at only 70℃ when its surface pressure is -0.07Mpa.FZG series drying machine is highly efficient even under low temperature condition.It is suitable for drying materials like pharmaceuticals,chemicals,foods,heavy and light industry products,thermally sensitive material too.
AAA1
Vacuum drying of high quality vegetable lyophilization / fruit vacuum freeze drying machine / meat freeze dryer is a process in which materials are dried in a reduced pressure environment, which lowers the heat needed for rapid drying. It does not take place in a true vacuum, despite the name. Devices used for this process are known as vacuum driers, and can vary in size from small units designed to fit on kitchen counters to massive rooms which are used to handle things like timber products.
AAA2
Drying involves reducing the moisture in an object, and is done in environments where the air is drier than the object being dried, which encourages moisture to evaporate out. This is often accomplished with heat to reduce the humidity of the air, but in a vacuum drier, the temperature does not need to be as high, and the drying is often faster. It's also possible to achieve a very high level of dryness, which may be desirable in some cases.
