Abstract

This aims to provide an evaporating-dehydrating apparatus, which can be simplified in an ambient-air intrusion preventing mechanism, can efficiently exchange heat, can prevent an object to be dried from sticking, and can suppress the energy consumption rate at the running time, and an evaporating-dehydrating apparatus, which can evaporate and dehydrate the object to be dried sufficiently in a drying container, can perform the efficient heat exchange, and can suppress the energy consumption rate at the running time. The evaporating-dehydrating apparatus comprises a discharge mechanism (40) for discharging the contents of the drying container (1). The discharge mechanism (40) includes a cylinder (41) communicating with a steam condenser (3), a piston (42) for pushing the object to be dried, which has moved from the inside of the drying container (1) through an outlet (1o) to a cylinder inside (41i), toward a cylinder outlet (41o) side, and a check valve (43) disposed in the cylinder outlet (41o). Moreover, the steam condenser (3) is constituted of a plurality of (e.g., two in pair) hollow rotors (units (3au)) extending in parallel.
