System and method for cooling moulds for foam polystyrene

摘要

A system and a method are described for cooling a mould, particularly for expanded polystyrene, by means of jets of water in a depressurized environment. Pumping means (6) are used to depressurize the environment and to remove therefrom the steam generated by the jets of water. The pumping means are arranged to perform the depressurization by suction directly from a steam-condensation device (2) connected (1) to the environment of the mould and having means (8-14) for cyclically discharging the water condensed in the condensation device. <IMAGE>
