Material drying and cooling integrated machine

A material drying and cooling integrated machine, comprising a heating module, a drying module, a dust removal filter module, a temperature-lowering and dehumidifying module, and a cooling module, wherein

• dry hot air generated in the heating module can enter the drying module to dry materials in the drying module;
• the dust removal filter module can conduct dust removal on air entering an interior thereof;
• the temperature-lowering and dehumidifying module can conduct temperature lowering and dehumidification on air entering the interior thereof so as to form dry cold air, and the dry cold air can enter the cooling module to cool materials in the cooling module;
• the dry hot air enters the drying module to dry the materials in the drying module, then damp hot air is formed, the damp hot air can enter the heating module, and part of the damp hot air can be heated by the heating module again and then enter the drying module;
• and an other part of the damp hot air can sequentially pass through the dust removal filter module and the temperature-lowering and dehumidifying module, dry cold air can be formed, and the dry cold air can enter the cooling module.
