To provide a heat exchanger of a garbage treatment apparatus that is capable of reducing the pressure loss at the back and forth of the folded part and that is capable of further enhancing the efficiency of the heat exchange.
The heat exchanger 9 which heats the garbage by performing the heat exchange of the garbage within the garbage treatment tank 2 is provided with a hollow heat exchanger body 10 fitted to the garbage treatment tank 2 in a state of being face-contacted with the outer peripheral surface of the garbage treatment tank 2. The inside of the heat exchanger body 10 is divided by a diaphragm 10e to form a passage 10f. Further, a turning-back part 10g to approximately reverse the flowing direction is formed at the proximity of the end of the diaphragm 10e, and a flow-straightening mechanism 16 to straighten the flow is arranged at the turning-back part 10g. The flow-straightening mechanism 16 is arranged at the turning-back part 16 so that each of both the ends is located at the two spaces divided by the extended line 10i of the diaphragm 10e to form the line symmetrical shape to the extended line 10i of the diaphragm 10e.
