摘要

Provided is a low-cost drying conveyor device with which a decrease in pH value does not occur, and with which exhaust accompanied by bad odors is not generated under high COD. This drying conveyor device is characterized by having buckets (17) in which coarse particles (2) are stored and transported, wind boxes (35) that supply heated air from the bottom of the buckets (17), a thermometer (56) that measures the device outlet temperature, and a heat exchanger (16) that adjusts the temperature of the heated air, with the temperature of the heated air being adjusted such that the device outlet temperature is 100°C or less.
