ABSTRACT:
A device is provided for shrinking shrinkable packages by heating by utilizing a liquid and/or gaseous heating medium, which reduces the amount of energy required. The novel device and method achieves its advantages by recovering heat by a recirculation apparatus (8, 9) for recovering heating medium which has evaporated from the liquid heating medium. The method relates to an operational process utilizing such a device.
