There are some differences between vacuum drying oven and blast drying oven in drying principle, temperature control, drying effect and price.
Similarity: vacuum drying oven and blast drying oven both play an important role in biochemistry, chemical and pharmaceutical, medical and health, agricultural research, environmental protection and other research applications, can be used as a drying experiment, is one of the necessary laboratory equipment.
Differences:
Working principle: vacuum drying box through the vacuum pump will air out, so that the indoor air pressure is reduced, so as to achieve the purpose of drying; while the blast drying box is heated by the electric heating element, and then through the blower will be the hot air circulating again and again, so as to achieve the purpose of drying.
Temperature control: the temperature control range of the vacuum drying oven is small, generally below room temperature; while the temperature control range of the blast drying oven is larger, and can reach high temperature.
Drying effect: the drying effect of the vacuum drying oven is better, suitable for easy oxidation, easy to deteriorate materials; while the blast drying oven is suitable for some materials that are not suitable for drying under vacuum.
Price: the price of vacuum drying oven is higher, while the price of blast drying oven is lower.
In summary, the two have their own characteristics, in the choice of use need to consider the specific needs. For more information, it is recommended to consult the relevant equipment and technical personnel.
