Comparison of the advantages and disadvantages of the bell-type freeze dryer and the in-situ freeze dryer
The small freeze dryer (laboratory freeze dryer) can be divided into two types: bell-type freeze dryer and in-situ freeze dryer.
Bell-type freeze dryer:
Advantages: Most of the experimental freeze dryers are bell-type, which has a simple structure and low cost. Most of the freeze-drying bins use a transparent plexiglass cover to facilitate the observation of the lyophilization of the material.
Disadvantages: The bell-type lyophilizer requires manual operation when it is transferred to the drying process after the material has been pre-frozen.
In situ freeze dryer:
Advantages: The pre-freezing and drying process of the material does not require manual operation.
Disadvantages: The manufacturing process of the freeze dryer is complicated and the manufacturing cost is high. However, the in-situ freeze dryer is the development direction of the freeze dryer, and is an ideal choice for the freeze-drying process. It is especially suitable for the freezing of medicines, biological products and other special products. dry.
