The difference between a gravity drying oven and an air blast oven can be described as follows:
A gravity drying oven relies on natural convection for heat distribution, while an air blast oven uses forced convection.
Gravity drying ovens utilize the natural circulation of air, with heat rising from the bottom to promote drying.
Air blast ovens, on the other hand, employ a fan or blower to actively circulate heated air throughout the oven chamber, ensuring faster and more uniform drying by directing hot air directly onto the items being dried.
Therefore, the key distinction between a gravity drying oven and an air blast oven lies in the method of heat distribution, with the former utilizing natural convection and the latter utilizing forced convection.
