摘要： A heated trough mangle comprises a frame, at least one mangle unit situated inside the frame and including a mangle cylinder with a perforated mangle surface and at least one heated mangle trough partially surrounding the mangle cylinder, an exhaust device with an exhaust air channel to withdraw exhaust air from inside the mangle cylinder to outside through the exhaust air channel, an air supply device to supply fresh air and having an air providing device, and an apparatus to transfer heat from one air stream to another air stream. The improvement comprises a heat exchanger with first and second flow chambers situated in each mangle unit, the first flow chamber of the heat exchanger being connected at one end to the mangle cylinder and connected at the other end to the exhaust device through the exhaust air channel, the second flow chamber being connected to the air supply device and forming a continuous fresh air supply channel. The air providing device of the air supply device terminates adjacent to the mangle cylinder so that the fresh air is continuously heated and supplied to the mangle unit to dry laundry pieces.
