To provide a heat exchange apparatus for a continuous belt-shaped packaging bag, which makes heat exchange of a content filling the packaging bag effective without allowing the packaging bag to come in direct contact with a heat treatment medium, and transfers the packaging bag while solving in advance a problem that leads to a sealing failure of the packaging bag.

According to the heat exchange treatment apparatus 2, the continuous belt-shaped packaging bag P is wounded helically around the outer surface of a rotating drum 4, which is a heat exchanging section, and a packaging bag support 16 for determining the transfer pitch of the packaging bag P is arranged underneath of the drum 4. The packaging bag support 16 comprises a plurality of guide fences 17 arranged at every a prescribed distance in the longitudinal direction of the drum 4, and guide bearing parts 18 formed to be inclined against the transfer direction of the packaging bag P between respective guide fences 17, where the helically arranged packaging bag P is supported by the guide fences 18 in a prescribed state.
