To reduce the leak of odor from a garbage treatment equipment by limiting exhaust gas volume at the initial stage of drying treatment operation.

A first heating means 15 that heats the bottom part of a container tank 10, an agitating member 20 that rotates along the inner wall of the bottom part of the container tank 10 driven by a rotation drive device 30, a second heating means 45 that heats the inside air of the container tank 10, a hot air fan 42 that circulates the inside air that is heated by the second heating means 45, an exhaust device 50 that exhausts the inside air of the container tank 10 to the outside, an exhaust fan that is driven to rotate at the upstream of the exhaust device 50, a deodorizing device that deodorizes the exhaust that flows into the downstream of the exhaust fan and a third heating means that heats the deodorizing device are provided. The exhaust fan is driven intermittently while the temperature inside the container tank 10 is low and the exhaust fan is driven continuously when the temperature of the container tank 10 rises to higher temperature.
