Types of Drying Ovens

There are various drying ovens. In terms of their performance, the drying ovens can be classified into the vacuum drying ovens, blast drying ovens, programmable drying ovens, explosion-proof drying ovens and hot air circulating drying ovens. Our company mainly deals in vacuum drying ovens and blast drying ovens, which will be introduced in detail as follows.

Whether vacuum drying ovens or blast drying ovens, both of them can be used for experiments of materials drying and play an important role in biochemistry, chemical, pharmaceutical, medical and health, agricultural scientific research, environmental protection and other research and application fields.

But they have completely different working principles.

How does a Vacuum Drying Oven Work?

The vacuum drying ovens make use of the principle of vacuum pumping to dry materials. Specifically speaking, it can make the space, where the material is, be under the negative pressure or vacuum condition. Under such circumstances, the boiling points of moisture, solvents or other volatile components will decrease so that they can be separated from the surface of the material particles and pumped away by the vacuum pump.

How does a Blast Drying Oven Work?

The blast drying ovens take advantage of the blast circulation in the box to drive air flows in order to achieve the purpose of drying. By extension, it can heat the moisture, solvents and volatile components to make the molecules move rapidly so that they can be separated from the material and the material can be dried. It has a fast drying speed and high drying temperature. Under the action of the fan, the volatile particles of the material evaporated from the material surface can be quickly taken away through the air exchange so as to achieve the purpose of drying materials rapidly.
