What is the difference between drying oven and vacuum drying oven

Publish Time: 2022-11-07
Vacuum drying oven: a drying oven with a working space under negative pressure. Vacuum drying oven is widely used in biochemistry, chemical pharmacy, medical and health, agricultural scientific research, environmental protection and other research and application fields, for powder drying, baking and disinfection and sterilization of various glass containers. It is especially suitable for rapid drying of heat-sensitive, easily decomposed, easily oxidized substances and complex components.

For example: candy moisture measurement, etc

Electric blast constant temperature drying oven: equipment for dehydration drying or heat treatment of specimens. Drying oven is a commonly used instrument and equipment, mainly used to dry samples, but also to provide the temperature environment required for experiments. Drying ovens are used in various industries such as chemical, electronics, casting, automotive, food, machinery and so on

Compared with conventional drying technology, it has the following advantages:

First, the vacuum environment greatly reduces the boiling point of the liquid that needs to be expelled, so vacuum drying can be easily applied to heat-sensitive substances;

Second, for samples that are not easy to dry, such as powders or other granular samples, the use of vacuum drying method can effectively shorten the drying time;
Third, various mechanical parts with complex structure or other porous samples are cleaned using vacuum drying method, and no residual substances are left after complete drying;

Fourth, the use is safer---- under vacuum or inert conditions, completely eliminate the possibility of oxide explosion when exposed to heat;

Compared with ordinary drying that relies on air circulation, powdered samples will not be blown or moved by flowing air;
