However, the existing ovens usually adopt a single blowing or fixed heating blowing mode to blow hot air to the surface of static stacked samples, usually first remove the water on the exposed part of the samples, then remove the water in the interior of the sample stack through continuous blowing, the drying time is long, the invalid heating is much, the energy consumption is high, and the uneven drying phenomenon is prone to occur, and for temperature-sensitive samples, the continuous hot air is prone to cause local overheating of the exposed part, which causes the samples to be ineffective or the activity to be reduced.

However, the above heat field uniform drying equipment is more suitable for most conventional materials, such as granular and blocky samples, and the tumbling effect is poor for powdery or easy-to-cake samples, which can easily lead to uneven drying and local heat concentration.
