Applications and advantages of vacuum freeze drying
1. Freeze-drying is at low temperature, so suitable for many kind of heat-sensitive materials, such as proteins, microorganisms etc. It won’t change their biological activity. Therefore it has been widely used in medicine.
2. It has little losses of volatile components dried at low temperature, very suitable for some chemical products, pharmaceuticals and food drying.
3. In the freeze-drying process, the microbial growth and the role of the enzyme stop, so they can maintain the original characters
4. It won’t shrink and keep original structures in freeze drying.
5. After drying, materials are spongy and porous, easy to dissolve and get the original shape.
6. Under vacuum condition with little oxygen, it will protect materials which is easy to get oxidized.
7. It can remove 95 to 99% of the water by freeze drying, so dried product can be stored for a long time without deterioration

Basic working principle of 50m2 500kg per batch vacuum freeze dryer lyophilizer for food 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 50m2 500kg per batch vacuum freeze dryer lyophilizer for food 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.
