Ⅰ Summary
1, Production Information

Vacuum freeze drying technique, named Lyophilization which is the

technique for pre-freezing the watery material first, then make moisture

sublimation under the vacuum. The biological and chemistry of Lyophilized

goods is unchanged, which is easy to long term time storage. The

lyophilized goods can resume the original status when water them. So

freeze-drying technique can be applied to the fields of medicine, foodstuff,

chemistry and biological science, etc.

FDL series freeze dryer has 5 configurations, as follows: Standard type:

The samples will be dried after be pre-frozen. .

Top- press type: Pre-freezing and drying the material in the bottle, then

fasten down the bottle cap by manual under the vacuum condition after the

freeze drying, which is equivalent to the vacuum package.

Manifold type: The samples inside of special bottles are connected

with freeze drying cover by rubber valve after pre-frozen. The customer can

change different type special bottles any time during freeze drying process

through switching valve, so different kind of samples can be freeze dried

together, and 8 different capacity bottles can be hang together also, which is
