Fruit dryers with bottom fan

Bottom

— the traditional and widely used location of the heater.

The widespread use of this heater arrangement is attributed to two main advantages. Firstly, the upward flow of warm air ensures a relatively uniform distribution of heat throughout the dryer's volume. Secondly, these devices have compact dimensions determined by the size of the trays, allowing for flexibility in placement. However, a drawback of the lower location is the potential for contamination on the heater, which can result in unpleasant odors and may require thorough cleaning. Manufacturers often implement measures to mitigate this issue, minimizing its impact.
