A device for allowing efficient drying and a method thereof are established by increasing the opportunity and area to bring a drying object into contact with air and a method for producing dry fermented feed and dry fermented manure at low costs by using the fermentation heat is proposed. The drying object is floated while shifting and stirring the drying object in the drying vessel, and air is supplied from below, and the drying object is transported by an air current repeatedly from a lower part to an upper part of the drying vessel to increase the opportunity and area to bring the drying object into contact with dry air evenly and significantly improve shortening of time spent for drying. By arranging air injection nozzles to generate an induced air current in the outside of an air current for blowing the drying object along with air to a lower inner wall and a curved inner wall of the circulation exhaust port in the circulation duct, the drying object is prevented from being damaged in the duct and smooth circulation thereof is realized, whereby an evenly dried product of good quality can be obtained. As for a drying object under a fermentation process, the opportunity and area to bring the drying object into contact with air evenly is increased in a stored place and transport by an air current so as to accelerate fermentation and drying, significantly improve shortening of time spent for drying, and produce a uniform quality product whose value is added by fermentation such as fermented feed/fermented manure of animal and plant residue, without using new thermal power. |
