Introduction of Freeze Dryer

The vacuum freezing drying technology, which is also called sublimation drying,
is a technical method that freezes the samples in advance, and then sublimates
its moisture in the vacuum state. Materials are easier for long term preservation
after freezing drying processing.

They can be restored to the original state and maintain its chemical and biological characteristics after being watered. So the freezing drying technology is widely used
in medicine, pharmacy, food production, chemistry industry and biological products etc.

LGJ-30F Freeze Dryer with stopper

LGJ-30F Freeze Dryer is suitable for a small amount production,
 freeze-drying experiment in laboratory or pilot scale test. 

 

This series of dryers have the heating shelf and the freeze drying process are made
 in the same place. It changes the traditional complicated operation and prevent the
 product from pollution.

 

Main Features

With heating shelf and PLC control standard

Freeze and drying process are completed in the same place

With organic glass observation window, the whole process is easy to see

The temperature error of shelf is less than or equal to 1℃

Fluid fills hollow shelves, with the most uniform shelf temperature and consistent 
and repeatable drying possible

Condenser is separated from drying chamber ,so the water capture capacity is better
 and drying time is shorter 

Liquid crystal display, English interface, display of drying curves
Internal surface of rectangular chamber and product tray are of stainless steel

Air-letin valve with nitrogen is optional

Eutectic point test device is optional
