In particular, it is pointed out that there is a concern of environmental pollution, and excessive maintenance and management costs are consumed due to these disadvantages.

In addition, the conventional hot air dryer has a structure in which agricultural products are placed on a multi-stage tray, followed by blowing hot hot air from the top or the bottom to dry it.

Therefore, there is a disadvantage that it is not possible to uniformly blow high temperature hot air evenly to the agricultural products placed on the multi-stage tray, and because of these disadvantages, there is a problem that the drying efficiency of agricultural products is different depending on the position of the tray.

On the other hand, in view of this, there is a method to change the position of the multi-stage tray to periodically supply a uniform hot air to all agricultural products. However, in this case, since the position of the multi-stage tray must be changed by hand, there is a problem that a lot of labor is required.

SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem, and an object thereof is to provide a agricultural product dryer which can dry agricultural products efficiently without any concern about environmental pollution and with low maintenance and management costs.
