Similarities:
Both vacuum oven and drying oven can be used for articles drying, baking wax,
sterilization, they all play an important role in biochemistry, chemical
pharmaceutical, medical and health, environmental protection and other research
and application fields, is one of the laboratories commonly used experimental
equipment.
Difference:
A vacuum oven is to use the principle of vacuum pumping to achieve the drying
of articles. The air blasting oven uses the air circulation cycle in the oven
to drive the hot airflow to achieve drying purposes.
How
to choose vacuum drying or blast drying?
The
vacuum environment of vacuum heating oven greatly reduces the boiling point of
the liquid that needs to be expelled, so vacuum drying can be easily applied to
thermosensitive substances; for samples that are not easy to dry, such as
powder or other granular samples, vacuum drying can effectively shorten the
drying time. Under vacuum or inert conditions, the possibility of thermal
explosion of oxides is completely eliminated; powder samples will not be blown
or moved by flowing air. If your samples are the above, you can choose a vacuum
drying oven. In addition, ordinary samples can choose a forced convection oven.
