Work principle

The working principle of the hot air drying oven:

It is mainly to heat the air in the room through the heating element, and then use the fan to help these hot air circulate evenly in the interior, the circulating process includes convection, conduction and radiation in three ways, so that the sample surface can be evenly contacted with the hot and dry air. In this process, the hot air is in contact with the sample surface, promoting the evaporation of moisture, so as to achieve the purpose of drying.

Advantages

The advantages of the hot air drying oven mainly include the following points:
a. Uniform heating
b. Rapid heating and drying
c. High safety performance
d. Precise temperature control
e. Energy saving and high efficiency
