Small lyophilizer (
Laboratory lyophilizer)
From the structure points, can be divided into: the bell jar type lyophilizer, in situ the lyophilizer.
the lyophilizer bell jar type:
advantage: most experimental lyophilizer for bell jar type, its simple structure, low cost.
Most use transparent organic glass, freeze-dried storehouse for observation materials of freeze-dried.
weakness: the bell jar type material for the lyophilizer is frozen into the drying process after the need manual operation.
In situ freeze-dry machine:
advantages: material precool, drying process without manual operation.
disadvantages: the making craft of the lyophilizer is complex, the manufacturing cost is high, but the lyophilizer is in situ lyophilizer development direction, is the ideal choice of the freeze-drying technology was groping, especially suitable for medicine, biological products and other special products of freeze-dried.
