Hereinafter, an embodiment according to the present invention will be described in detail with reference to FIGS. 3 to 5.

The waste is waste that is crushed by the selective removal of ferrous metals in the pretreatment process, and the water content is not constant and the weight is not constant. Generally, waste is classified into heavy waste and light weight waste in a dry state. Heavy waste is food, ultra-magnetic, non-ferrous metals, plastics, etc., and non-flammable waste except food and plastics. And the like are flammable wastes. Thus, the heavy wastes, except for super magnetics and nonferrous metals, can be recycled as product materials, and the light wastes can optionally be made as waste solid raw materials (RDF) together with heavy wastes except for super magnetics and non-ferrous metals.

Therefore, the drying apparatus of the present embodiment focuses on controlling the amount of drying and sorting heavy waste and light waste according to the degree of blowing by transporting the waste of which water content is not constant by hot wind while drying by hot wind. .

In addition, heavy wastes (food, plastic, non-ferrous metals, supermagnetics, etc.) are blown by a predetermined distance by hot air in the rotating inner case 10b and transferred to the waste outflow hood part 30, and then the rotating inner case 10b. Stagnates at the bottom within Then, the waste of weight stagnated at the bottom in the rotating inner case 10b is integrally attached to the inner circumferential surface of the rotating inner case 10b as shown in FIG. 4 as the rotating inner case 10b rotates. As described above, the shovel 50 is also rotated to be guided by the shovel 50 to the upper portion of the rotating inner case 10b to naturally fall to the bottom of the rotating inner case 10b.

The waste of weight naturally falling by the shovel 50 in the rotating inner case 10b is again blown by a predetermined distance in the rotating inner case 10b by hot air. Therefore, for example, non-ferrous metals, supermagnetics, plastics, foods, etc., which are heavy wastes, are stagnated and transported several times in the rotary inner case 10b to be dried more than lighter wastes, and thus the waste outflow hood part ( 30) is guided to the side.
